| 1 | Biosorption characteristics of unicellular green alga Chlorella sorokiniana immobilized in loofa sponge for removal of Cr(Ⅲ)显示文摘Loofa sponge(LS)immobilized biomass of Chlorella sorokiniana(LSIBCS),isolated from industrial wastewater,was investigated as a new biosorbent for the removal of Cr(Ⅲ)from aqueous solution.A comparison of the biosorption of Cr(Ⅲ)by LSIBCS and free biomass of C.sorokiniana(FBCS)from 10-300 mg Cr(Ⅲ)/L aqueous solutions showed an increase in uptake of 17.79% when the rnicroalgal biomass was immobilized onto loofa sponge.Maximum biosorption capacity for LSIBCS and FBCS was found to be 69.26 and 58.80 mg Cr(Ⅲ)/g biosorbent,respectively,whereas the amount of Cr(Ⅲ)ions adsorbed onto naked LS was 4.97 mg/g.The kinetics of Cr(Ⅲ)biosorption was extremely rapid and equilibrium was established in about 15 and 20 min by LSIBCS and FBCS, respectively.The biosorption equilibrium was well defined by Langrnuir adsorption isotherm model.The biosorption kinetics followed the pseudo-second order kinetic model.The biosorption was found to be pH dependent and the maximum sorption occurred at the solution pH 4.0.Desorption studies showed that 98% of the adsorbed Cr(Ⅲ)could be desorbed with 0.1 mol/L HNO_3,while other desorbing agents were less effective in the order:EDTA>H_2SO_4>CH_3COOH>HCl.The regenerated LSIBCS retained 92.68% of the initial Cr(Ⅲ)binding capacity up to five cycles of reuse in continuous flow-fixed bed columns.The study revealed that LSIBCS could be used as an effective biosorbent for the removal of Cr(Ⅲ)from wastewater. | AKHTAR Nasreen IQBAL Muhammad ZAFAR Saeed Iqbal IQBAL Javed | 2008 | Journal of Environmental Sciences2008，20，2： | 20 |

| 3 | Enhanced photocatalytic activity of Ce-doped ZnO nanopowders synthesized by combustion method显示文摘Facile and fast combustion method was used to synthesize Zn O and Ce-doped Zn O(CZO) nanocrystalline powders photocatalysts with different cerium concentrations(0.5 wt.%–10.0 wt.%) followed by calcination at 700 oC for 3 h. The prepared samples were characterized by a variety of characterization techniques such as X-ray diffraction(XRD), scanning electron microscopy(SEM) combined with energy dispersive X-ray diffraction(EDX), transmission electron microscopy(TEM), UV-visible spectroscopy, BET surface area analyser and photoluminescence spectroscopy(PL), to study the crystal structure, surface morphology, chemical composition and optical properties. It was observed from XRD results that synthesized powders had hexagonal wurtzite structure with the smallest crystallite size about 13 nm. Absorption spectra showed that cerium doping enhanced the light absorption properties towards the visible light region. Photoluminescence spectra for Ce-doped Zn O samples exhibited relatively weak near band edge(NBE) emission peaks as compared to that of pristine Zn O. The photocatalytic activities of the prepared samples were evaluated by photocatalytic degradation of Rhodamine B(Rh B) under UV light and visible light(λ≥420 nm) irradiation. The textile mill effluent containing organic matters was also treated under sunlight using photocatalysis and the reduction in the chemical oxygen demand(COD) of the treated effluent revealed a complete destruction of the organic molecules along with colour removal. The results showed that the CZO photocatalyst doped with 3.0 wt.% cerium exhibited four times enhanced photocatalytic activity compared to pure Zn O. The enhanced photocatalytic activity could be attributed to extended visible light absorption and inhibition of the electron-hole pair's recombination. | M.Ahmad E.Ahmed Fezza Zafar N.R.Khalid N.A.Niaz Abdul Hafeez M.Ikram M.Ajmal Khan 洪樟连 | 2015 | Journal of Rare Earths2015，33，3： | 13 |
| 4 | Impact of on-range choice feeding with black soldier fly larvae(Hermetia illucens)on flock performance,egg quality,and range use of free-range laying hens显示文摘Semi-intensive free-range farm systems are common in Australia, and these systems frequently practise on-range feeding. The objective of this study was to investigate the benefit of on-range choice feeding on flock performance, egg quality, and range use of free-range laying hens using black soldier fly larvae(Hermetia illucens, BSF). A total of 160 mature ISA brown laying hens, previously determined to range daily, were allocated to a control group(control) or a treatment group(BSF) with various replicates depending on the parameter investigated. All hens were fed ad libitum indoors with a wheat-soy based diet formulated according to breed requirements. Black soldier fly hens were offered dried BSF larvae ad libitum on the range. Body weight, feed intake, BSF intake, egg production, feed conversion ratio, internal and external egg quality parameters, and individual range use using radio-frequency identification(RFID)technology was evaluated. Black soldier fly hens consumed on average 15 ± 1.7 g BSF larvae/hen per day.There were no differences between BSF and control hens for any of the performance parameters obtained(P > 0.05). Egg weight, shell weight, and shell thickness of eggs from BSF hens were significantly lower(P = 0.003, P = 0.001, and P = 0.004, respectively) than those of eggs from control hens. Egg yolk colour was significantly paler in eggs from BSF hens(P < 0.001). No significant ranging differences between the BSF and control hens were observed(P > 0.05) except for BSF hens showing longer total maximum time for a single visit to the range(P = 0.011). In conclusion, the average intake of BSF larvae indicated a good level of acceptance. Feed formulation should be adjusted for the intake of the choice fed source. The impact of choice-feeding on range use was minor. | Isabelle Ruhnke Camille Normant Dana L.M.Campbell Zafar Iqbal Caroline Lee Geoff N.Hinch Julie Roberts | 2018 | Animal Nutrition2018，，4： | 12 |
| 5 | Advances in fabrication of ceramic corundum abrasives based on sol–gel process显示文摘Corundum abrasives with good chemical stability can be fabricated into various free abrasives and bonded abrasive tools that are widely used in the precision machining of various parts.However,these abrasives cannot satisfy the machining requirements of difficult-to-machine materials with high hardness,high strength,and strong wearing resistance.Although superhard abrasives can machine the above-mentioned materials,their dressing and manufacturing costs are high.By contrast,ceramic corundum abrasives fabricated by sol–gel method is a costeffective product between conventional and superhard abrasives.Ceramic corundum abrasives exhibit self-sharpening and high toughness.In this review,the optimization methods of ceramic corundum abrasive properties are introduced from three aspects:precursor synthesis,particle shaping,and sintering.Firstly,the functional mechanism of seeds and additives on the microstructural and mechanical properties of abrasives is analyzed.Specifically,seeds can reduce the phase transition temperature and improve fracture toughness.The grain size and uniformly dense structure can be controlled by applying an appropriate amount of multicomponent additives.Then,the urgent need of engineering application and machinability of special shape ceramic corundum abrasives is reviewed,and three methods of abrasive shaping are summarized.The micromold replication technique is highly advanced and can be used to prepare functional abrasives.Additionally,the influence of a new sintering method,namely,two-step sintering technique,on the microstructural and mechanical performance of ceramic corundum abrasives is summarized.Finally,the challenge and developmental trend of the optimization of ceramic corundum abrasives are prospected. | Baoteng HUANG Changhe LI Yanbin ZHANG Wenfeng DING Min YANG Yuying YANG Han ZHAI Xuefeng XU Dazhong WANG Sujan DEBNATH Muhammad JAMIL Hao Nan Li Hafiz Muhammad ALI Munish Kumar GUPTA Zafar SAID | 2021 | Chinese Journal of Aeronautics2021，34，6： | 11 |
| 6 | Somatic embryogenesis in wild relatives of cotton (Gossypium Spp.)显示文摘Wild cotton species can contribute a valuable gene pool for agronomically desirable cultivated tetraploid cultivars. In order to exploit diploid cotton a regeneration system is required to achieve transformation based goals. The present studies aimed at optimizing the conditions for regeneration of local varieties as well as wild species of cotton. Different callus induction media were tested with varying concentrations of hormones in which sucrose was used as nutritional source. Different explants (hypo-cotyls, cotyledon, root) were used to check the regeneration of both local cotton plants and wild relatives using T & G medium, BAP medium, CIM medium, EMMS medium, and cell suspension medium. Different stages of embryogenicity such as early torpedo stage, late torpedo stage, heart stage, globular stage and cotyledonary stage were observed in wild relatives of cotton. The results of this study pave the way for establishing future transformation methods. | RAO Abdul Qayyum HUSSAIN S. Sarfraz SHAHZAD M. Saqib BOKHARI S. Yassir Abbas RAZA M.

| 7 | Effect of chromium on growth attributes in sunflower(Helianthus annuus L.)显示文摘Heavy metal soil pollution takes place when the metal concentration of soil exceeds natural background level and causes ecological destruction and deterioration of the environment.In the present study,a pot experiment was conducted to evaluate the effect of chromium-contaminated soil in sunflower(Helianthus annuus L.)growth attributes.Three different levels of chromium(Cr)i.e.,20, 40,and 60 mg/kg were applied to three varieties of sunflower(G-3,G-9,and G-59).The results of morphological,chemical,and yield parameters were recorded at crop maturity.The result showed that germination,root,and shoot lengths were decreased with increase in Cr concentrations.A gradual decrease was observed for various morphological parameters like root fresh and dry weights,shoot fresh and dry weights,and plant height with increase in Cr levels.A comparison among Cr treatments obtained a significant decrease in yield parameters as achenes/capitulum,achenes/plant,and 100 achenes weight in three varieties.Cr was significantly absorbed by roots but its transport to other parts of plants was slow,and uptake in seeds was much lower than in roots and shoots. | FOZIA Andaleeb MUHAMMAD Anjum Zia MUHAMMAD Ashraf ZAFAR Mahmood Khalid | 2008 | Journal of Environmental Sciences2008，20，12： | 9 |
| 8 | 基于USLE模型的祁连山国家公园土壤水力侵蚀评价显示文摘基于通用土壤流失方程(USLE)模型对2005、2010和2015年祁连山国家公园土壤水力侵蚀情况进行计算和分析,为本地区的土壤侵蚀防治提供决策建议。经计算方法选择、插值方法对比、同类研究类比、统计分析,获得每年及平均土壤水力侵蚀空间强度与等级分类。结果表明:2005—2015年,祁连山国家公园的土壤水力侵蚀水平有所下降,土壤侵蚀量由2005年的6314.26万t/a下降至2015年的5755.59万t/a;就土壤侵蚀等级来说,研究区范围内70%的区域属于微度侵蚀,整体上土壤侵蚀强度水平较低;土壤水力侵蚀主要发生在高程为≥3600~4600 m的区域和≥8°~15°的缓坡,而高程≥4600 m的区域贡献25.67%的侵蚀量,如果冰川积雪退缩,裸土面临暴露,可能加重土壤侵蚀。因此在国家公园未来发展与土壤侵蚀防治过程中,需要严格保护3600~4600 m的高程带,以及5°~15°缓坡地带的自然环境,同时保护冰川与永久积雪。 | 陈豪 丁文广 Tanjia Binte Zafar | 2020 | 中国水土保持科学2020，18，4： | 9 |
| 9 | Cryogenic minimum quantity lubrication machining: from mechanism to application显示文摘Cutting fluid plays a cooling-lubrication role in the cutting of metal materials.However,the substantial usage of cutting fluid in traditional flood machining seriously pollutes the environment and threatens the health of workers.Environmental machining technologies,such as dry cutting,minimum quantity lubrication(MQL),and cryogenic cooling technology,have been used as substitute for flood machining.However,the insufficient cooling capacity of MQL with normal-temperature compressed gas and the lack of lubricating performance of cryogenic cooling technology limit their industrial application.The technical bottleneck of mechanical-thermal damage of difficult-to-cut materials in aerospace and other fields can be solved by combining cryogenic medium and MQL.The latest progress of cryogenic minimum quantity lubrication(CMQL)technology is reviewed in this paper,and the key scientific issues in the research achievements of CMQL are clarified.First,the application forms and process characteristics of CMQL devices in turning,milling,and grinding are systematically summarized from traditional settings to innovative design.Second,the cooling-lubrication mechanism of CMQL and its influence mechanism on material hardness,cutting force,tool wear,and workpiece surface quality in cutting are extensively revealed.The effects of CMQL are systematically analyzed based on its mechanism and application form.Results show that the application effect of CMQL is better than that of cryogenic technology or MQL alone.Finally,the prospect,which provides basis and support for engineering application and development of CMQL technology,is introduced considering the limitations of CMQL. | Mingzheng LIU Changhe LI Yanbin ZHANG Qinglong AN Min YANG Teng GAO Cong MAO Bo LIU Huajun CAO Xuefeng XU Zafar SAID Sujan DEBNATH Muhammad JAMIL Hafz Muhammad ALI Shubham SHARMA | 2021 | Frontiers of Mechanical Engineering2021，16，4： | 8 |
| 10 | Factors Associated with Peripheral Neuropathy in Type 2 Diabetes: Subclinical versus Confirmed Neuropathy显示文摘This study determined the prevalence of diabetic peripheral neuropathy(DPN) and subclinical DPN(s DPN) in patients with type 2 diabetes mellitus(T2DM) using nerve conduction study(NCS) as a diagnostic tool. We also investigated the factors associated with the development of s DPN and compared factors between the sD PN and confirmed DPN(cDPN). This cross-sectional study involved 240 T2DM patients who were successively admitted to the endocrinology wards of Wuhan Union Hospital over the period of January to December 2014. Data on the medical history, physical and laboratory examinations were collected. DPN was diagnosed using NCS. One-way ANOVA with least significant difference(LSD) analysis or chi-square tests was used to compare parameters among DNP-free, s DPN and c DPN patients. Independent factors associated with s DPN were determined using logistic regression. The results showed that 50.8% of the participants had DPN, and among them, 17.1% had sDPN. sDPN showed significant independent associations with age, height, HbA1c, presence of atherosclerosis and diabetic retinopathy. Patients with DPN differed significantly from those without DPN with respect to age, duration of disease(DOD), HbA1c, presence of atherosclerosis, diabetic retinopathy, nephropathy and hypertension. Patients with cDPN, relative to those with sDPN, had significantly longer DOD and higher prevalence of peripheral artery disease(PAD) and coronary artery disease(CAD). Our study suggests that a significant number of T2DM patients are affected by s DPN, and the development of this condition is associated with advanced age, tall stature, poor glycaemic control, presence of diabetic retinopathy and atherosclerosis. On the other hand, patients with cDPN tend to have a longer DOD and are more likely to suffer from PAD and CAD. | Yogendranathsing Unmar Mohammad Ishraq Zafar 高峰 | 2017 | Journal of Huazhong University of Science and Technology(Medical Sciences)2017，37，3： | 8 |
| 11 | Saline-Alkali Tolerance in Rice: Physiological Response, Molecular Mechanism, and QTL Identification and Application to Breeding显示文摘Salinity-alkalinity is incipient abiotic stress that impairs plant growth and development.Rice(Oryza sativa)is a major food crop greatly affected by soil salinity and alkalinity,requiring tolerant varieties in the saline-alkali prone areas.Understanding the molecular and physiological mechanisms of saline-alkali tolerance paves the base for improving saline-alkali tolerance in rice and leads to progress in breeding.This review illustrated the physiological consequences,and molecular mechanisms especially signaling and function of regulating genes for saline-alkali tolerance in rice plants.We also discussed QTLs regarding saline-alkali tolerance accordingly and ways of deployment for improvement.More efforts are needed to identify and utilize the identified QTLs for saline-alkali tolerance in rice. | Ratan Kumar GANAPATI Shahzad Amir NAVEED Sundus ZAFAR WANG Wensheng XU Jianlong | 2022 | Rice science2022，29，5： | 8 |
| 12 | Milling Force Model for Aviation Aluminum Alloy: Academic Insight and Perspective Analysis显示文摘Aluminum alloy is the main structural material of aircraft,launch vehicle,spaceship,and space station and is processed by milling.However,tool wear and vibration are the bottlenecks in the milling process of aviation aluminum alloy.The machining accuracy and surface quality of aluminum alloy milling depend on the cutting parameters,material mechanical properties,machine tools,and other parameters.In particular,milling force is the crucial factor to determine material removal and workpiece surface integrity.However,establishing the prediction model of milling force is important and difficult because milling force is the result of multiparameter coupling of process system.The research progress of cutting force model is reviewed from three modeling methods:empirical model,finite element simulation,and instantaneous milling force model.The problems of cutting force modeling are also determined.In view of these problems,the future work direction is proposed in the following four aspects:(1)high-speed milling is adopted for the thin-walled structure of large aviation with large cutting depth,which easily produces high residual stress.The residual stress should be analyzed under this particular condition.(2)Multiple factors(e.g.,eccentric swing milling parameters,lubrication conditions,tools,tool and workpiece deformation,and size effect)should be considered comprehensively when modeling instantaneous milling forces,especially for micro milling and complex surface machining.(3)The database of milling force model,including the corresponding workpiece materials,working condition,cutting tools(geometric figures and coatings),and other parameters,should be established.(4)The effect of chatter on the prediction accuracy of milling force cannot be ignored in thin-walled workpiece milling.(5)The cutting force of aviation aluminum alloy milling under the condition of minimum quantity lubrication(mql)and nanofluid mql should be predicted. | Zhenjing Duan Changhe Li Wenfeng Ding Yanbin Zhang Min Yang Teng Gao Huajun Cao Xuefeng Xu Dazhong Wang Cong Mao Hao Nan Li Gupta Munish Kumar Zafar Said Sujan Debnath Muhammad Jamil Hafiz Muhammad Ali | 2021 | Chinese Journal of Mechanical Engineering2021，34，1： | 7 |

| 14 | Laboratory scale studies on removal of chromium from industrial wastes显示文摘Chromium being one of the major toxic pollutants is discharged from electroplating and chrome tanning processes and is also found in the effluents of dyes, paint pigments, manufacturing units etc. Chromium exists in aqueous systems in both trivalent (Cr 3+) and hexavalent (Cr 6+) forms. The hexavalent form is carcinogenic and toxic to aquatic life, whereas Cr 3+ is however comparatively less toxic. This study was undertaken to investigate the total chromium removal from industrial effluents by chemical means in order to achieve the Pakistan NEQS level of 1 mg/L by the methods of reduction and precipitation. The study was conducted in four phases. In phase Ⅰ, the optimum pH and cost effective reducing agent among the four popular commercial chemicals was selected. As a result, pH of 2 was found to be most suitable and sodium meta bisulfate was found to be the most cost effective reducing agent respectively. Phase Ⅱ showed that lower dose of sodium meta bisulfate was sufficient to obtain 100 % efficiency in reducing Cr 6+ to Cr 3+, and it was noted that reaction time had no significance in the whole process. A design curve for reduction process was established which can act as a tool for treatment of industrial effluents. Phase Ⅲ studies indicated the best pH was 8.5 for precipitation of Cr 3+ to chromium hydroxide by using lime. An efficiency of 100 % was achievable and a settling time of 30 minutes produced clear effluent. Finally in Phase Ⅳ actual waste samples from chrome tanning and electroplating industries, when precipitated at pH of 12 gave 100 % efficiency at a settling time of 30 minutes and confirmed that chemical means of reduction and precipitation is a feasible and viable solution for treating chromium wastes from industries. | M.A.Baig Mohsin Mir Shazad Murtaza Zafar I.

| 15 | Nano-enhanced biolubricant in sustainable manufacturing:From processability to mechanisms显示文摘To eliminate the negative effect of traditional metal-working fluids and achieve sustainable manufacturing,the usage of nano-enhanced biolubricant(NEBL)is widely researched in minimum quantify lubrication(MQL)machining.It's improved tool wear and surface integrity have been preliminarily verified by experimental studies.The previous review papers also concluded the major influencing factors of processability including nano-enhancer and lubricant types,NEBL concentration,micro droplet size,and so on.Nevertheless,the complex action of NEBL,from preparation,atomization,infiltration to heat transfer and anti-friction,is indistinct which limits preparation of process specifications and popularity in factories.Especially in the complex machining process,in-depth understanding is difficult and meaningful.To fll this gap,this paper concentrates on the comprehensive quantitative assessment of processability based on tribological,thermal,and machined surface quality aspects for NEBL application in turning,milling,and grinding.Then it attempts to answer mechanisms systematically considering multi-factor influence of molecular structure,physicochemical properties,concentration,and dispersion.Firstly,this paper reveals advanced lubrication and heat transfer mechanisms of NEBL by quantitative comparison with biolubricant-based MQL machining.Secondly,the distinctive filmformation,atomization,and infiltration mechanisms of NEBL,as distinguished from metal-working fluid,are clarified combining with its unique molecular structure and physical properties.Furtherly,the process optimization strategy is concluded based on the synergistic relationship analysis among process variables,physicochemical properties,machining mechanisms,and performance of NEBL.Finally,the future development directions are put forward aiming at current performance limitations of NEBL,which requires improvement on preparation and jet methods respects.This paper will help scientists deeply understand effective mechanism,formulate process specifications,and find future development trend of this technology. | Yanbin ZHANG Hao Nan LI Changhe LI Chuanzhen HUANG Hafiz Muhammad ALI Xuefeng XU Cong MAO Wenfeng DING Xin CUI Min YANG Tianbiao YU Muhammad JAMIL Munish Kumar GUPTA Dongzhou JIA Zafar SAID | 2022 | Friction2022，10，6： | 5 |
| 16 | Analysis of grinding mechanics and improved grinding force model based on randomized grain geometric characteristics显示文摘Too high grinding force will lead to a large increase in specific grinding energy, resulting in high temperature in grinding zone, especially for the aerospace difficult cutting metal materials,seriously affecting the surface quality and accuracy. At present, the theoretical models of grinding force are mostly based on the assumption of uniform or simplified morphological characteristics of grains, which is inconsistent with the actual grains. Especially for non-engineering grinding wheel,most geometric characteristics of grains are ignored, resulting in the calculation accuracy that cannot guide practical production. Based on this, an improved grinding force model based on random grain geometric characteristics is proposed in this paper. Firstly, the surface topography model of CBN grinding wheel is established, and the effective grain determination mechanism in grinding zone is revealed. Based on the known grinding force model and mechanical behavior of interaction between grains and workpiece in different stages, the concept of grain effective action area is proposed. The variation mechanism of effective action area under the influence of grain geometric and spatial characteristics is deeply analyzed, and the calculation method under random combination of five influencing parameters is obtained. The numerical simulation is carried out to reveal the dynamic variation process of grinding force in grinding zone. In order to verify the theoretical model, the experiments of dry grinding Ti-6Al-4 V are designed. The experimental results show that under different machining parameters, the results of numerical calculation and experimental measurement are in good agreement, and the minimum error value is only 2.1 %, which indicates that the calculation accuracy of grinding force model meets the requirements and is feasible. This study will provide a theoretical basis for optimizing the wheel structure, effectively controlling the grinding force range, adjusting the grinding zone temperature and improving the workpiece machining quality in the industrial grinding process. | Mingzheng LIU Changhe LI Yanbin ZHANG Min YANG Teng GAO Xin CUI Xiaoming WANG Wenhao XU Zongming ZHOU Bo LIU Zafar SAID Runze LI Shubham SHARMA | 2023 | Chinese Journal of Aeronautics2023，36，7： | 5 |
| 17 | Algal biomass as a global source of transport fuels:Overview and development perspectives显示文摘As a result of the global fuel crisis of the early 1970 s,coupled with concerns for the environment,the use of biofuel has been on the increase in many regions throughout the world.At present,a total of approximately 30 billion(30×109) liters of biofuel are utilized worldwide annually,although most countries rely hugely on the first generation biofuel.The limitations of the first and second generation biofuel gave rise to current interest in algae as a promising alternative to these conventional biofuel sources.Algal biomass could provide a lion's share of the global transport fuel requirements in future.The present review highlights some important developments in,and potentials of algaculture as a major biomass resource of the future.However,the major constraint to commercial-scale algae farming for energy production is the cost factor,which must be addressed adequately before its potentials can be harnessed. | Kifayat Ullah Mushtaq Ahmad Sofia Vinod Kumar Sharma Pengmei Lu Adam Harvey Muhammad Zafar Shazia Sultana C.N.Anyanwu | 2014 | Progress in Natural Science:Materials International2014，24，4： | 5 |

| 19 | Electrostatic atomization minimum quantity lubrication machining:from mechanism to application显示文摘Metal cutting fluids(MCFs)under flood conditions do not meet the urgent needs of reducing carbon emission.Biolubricant-based minimum quantity lubrication(MQL)is an effective alternative to flood lubrication.However,pneumatic atomization MQL has poor atomization properties,which is detrimental to occupational health.Therefore,electrostatic atomization MQL requires preliminary exploratory studies.However,systematic reviews are lacking in terms of capturing the current research status and development direction of this technology.This study aims to provide a comprehensive review and critical assessment of the existing understanding of electrostatic atomization MQL.This research can be used by scientists to gain insights into the action mechanism,theoretical basis,machining performance,and development direction of this technology.First,the critical equipment,eco-friendly atomization media(biolubricants),and empowering mechanisms of electrostatic atomization MQL are presented.Second,the advanced lubrication and heat transfer mechanisms of biolubricants are revealed by quantitatively comparing MQL with MCF-based wet machining.Third,the distinctive wetting and infiltration mechanisms of electrostatic atomization MQL,combined with its unique empowering mechanism and atomization method,are compared with those of pneumatic atomization MQL.Previous experiments have shown that electrostatic atomization MQL can reduce tool wear by 42.4%in metal cutting and improve the machined surface Ra by 47%compared with pneumatic atomization MQL.Finally,future development directions,including the improvement of the coordination parameters and equipment integration aspects,are proposed. | Wenhao Xu Changhe Li Yanbin Zhang Hafiz Muhammad Ali Shubham Sharma Runze Li Min Yang Teng Gao Mingzheng Liu Xiaoming Wang Zafar Said Xin Liu Zongming Zhou | 2022 | International Journal of Extreme Manufacturing2022，4，4： | 4 |
| 20 | Overexpression of the phytochrome B gene from Arabidopsis thaliana increases plant growth and yield of cotton (Gossypium hirsutum)显示文摘The phytochrome B (PHYB) gene of Arabidopsis thaliana was introduced into cotton through Agrobacterium tumefaciens.Integration and expression of PHYB gene in cotton plants were confirmed by molecular evidence.Messenger RNA (mRNA) expression in one of the transgenic lines,QCC11,was much higher than those of control and other transgenic lines.Transgenic cotton plants showed more than a two-fold increase in photosynthetic rate and more than a four-fold increase in transpiration rate and stomatal conductance.The increase in photosynthetic rate led to a 46% increase in relative growth rate and an 18% increase in net assimilation rate.Data recorded up to two generations,both in the greenhouse and in the field,revealed that overexpression of Arabidopsis thaliana PHYB gene in transgenic cotton plants resulted in an increase in the production of cotton by improving the cotton plant growth,with 35% more yield.Moreover,the presence of the Arabidopsis thaliana PHYB gene caused pleiotropic effects like semi-dwarfism,decrease in apical dominance,and increase in boll size. | Abdul Qayyum RAO Muhammad IRFAN Zafar SALEEM Idrees Ahmad NASIR Sheikh RIAZUDDIN Tayyab HUSNAIN | 2011 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2011，12，4： | 4 |
