| 1 | Anisotropic coding metamaterials and their powerful manipulation of differently polarized terahertz waves显示文摘Metamaterials based on effective media can be used to produce a number of unusual physical properties(for example,negative refraction and invisibility cloaking)because they can be tailored with effective medium parameters that do not occur in nature.Recently,the use of coding metamaterials has been suggested for the control of electromagnetic waves through the design of coding sequences using digital elements‘0’and‘1,'which possess opposite phase responses.Here we propose the concept of an anisotropic coding metamaterial in which the coding behaviors in different directions are dependent on the polarization status of the electromagnetic waves.We experimentally demonstrate an ultrathin and flexible polarization-controlled anisotropic coding metasurface that functions in the terahertz regime using specially designed coding elements.By encoding the elements with elaborately designed coding sequences(both 1-bit and 2-bit sequences),the x-and y-polarized waves can be anomalously reflected or independently diffused in three dimensions.The simulated far-field scattering patterns and near-field distributions are presented to illustrate the dual-functional performance of the encoded metasurface,and the results are consistent with the measured results.We further demonstrate the ability of the anisotropic coding metasurfaces to generate a beam splitter and realize simultaneous anomalous reflections and polarization conversions,thus providing powerful control of differently polarized electromagnetic waves.The proposed method enables versatile beam behaviors under orthogonal polarizations using a single metasurface and has the potential for use in the development of interesting terahertz devices. | Shuo Liu Tie Jun Cui Quan Xu Di Bao Liangliang Du Xiang Wan Wen Xuan Tang Chunmei Ouyang Xiao Yang Zhou Hao Yuan Hui Feng Ma Wei Xiang Jiang Jiaguang Han Weili Zhang Qiang Cheng | 2016 | Light(Science & Applications)2016,5,1: | 36 |
| 2 | Preliminary 3D printing of large inclined-shaped alumina ceramic parts by direct ink writing显示文摘Three dimensional(3D)printing technology by direct ink writing(DIW)is an innovative complex shaping technology,possessing advantages of flexibility in fabrication,high efficiency,low cost,and environmental-friendliness.Herein,3D printing of complex alumina ceramic parts via DIW using thermally induced solidification with carrageenan swelling was investigated.The rheological properties of the slurry under different thermally-induced modes were systematically studied.The solidification properties of thermally-induced pastes with varying contents of carrageenan were optimized.The experimental results showed that the optimized paste consisting of 0.4 wt%carrageenan could be rapidly solidified at about 55℃,which could print inclined-plane more than 60°in vertical without support,resulting in better homogeneity of the green body.A nearly pore-free structure was obtained after sintering at 1600℃ for 2 h. | Liangliang YANG Xiaojun ZENG Allah DITTA Bo FENG Lizhong SU Yue ZHANG | 2020 | Journal of Advanced Ceramics2020,9,3: | 9 |
| 3 | Tuning Superhydrophobic Materials with Negative Surface Energy Domains显示文摘Hydrophobic/superhydrophobic materials with intrinsic water repellence are highly desirable in engineering fields including antiicing in aerocrafts,antidrag and anticorrosion in ships,and antifog and self-cleaning in optical lenses,screen,mirrors,and windows.However,superhydrophobic material should have small surface energy(SE)and a micro/nanosurface structure which can reduce solid-liquid contact significantly.The low SE is generally found in organic materials with inferior mechanical properties that is undesirable in engineering.Intriguingly,previous theoretical calculations have predicted a negative SE forθ-alumina(θ-Al_(2)O_(3)),which inspires us to use it as a superhydrophobic material.Here,we report the experimental evidence of the small/negative SE ofθ-Al_(2)O_(3) and aθ-Al_(2)O_(3)-based superhydrophobic coating prepared by one-step scalable plasma arcing oxidation.The superhydrophobic coating has complete ceramic and desired micro/nanostructure and therefore exhibits excellent aging resistance,wear resistance,corrosion resistance,high-temperature tolerance,and burning resistance.Owing to the rarity of the small/negative SE in inorganic materials,the concept to reduce SE byθ-Al_(2)O_(3) may foster a blowout to develop robust superhydrophobicity by complete inorganic materials. | Zhongzhen Wu Liangliang Liu Shunning Li Shunping Ji Pinghu Chen Suihan Cui Zhengyong Ma Yuchang Weng Qian Huang Zhongcan Wu Hao Wu Yuan Lin Ricky KYFu Hai Lin Xiubo Tian Paul KChu Feng Pan | 2019 | Research2019,,1: | 6 |
| 4 | In-situ optimizing the valence configuration of vanadium sites in NiV-LDH nanosheet arrays for enhanced hydrogen evolution reaction显示文摘Developing the highly active, cost-effective, environmental-friendly, and ultra-stable nonprecious electrocatalysts for hydrogen evolution reaction(HER) is distinctly indispensable for the large-scale practical applications of hydrolytic hydrogen production. Herein, we report the synthesis of well-integrated electrode, NiV layered double hydroxide nanosheet array grown in-situ on porous nickel foam(abbreviated as in-NiV-LDH/NF) via the facile one-step hydrothermal route. Interestingly, the valence configuration of vanadium(V) sites in such NiV-LDH are well dominated by the innovative use of NF as the reducing regulator, achieving the reassembled in-NiV-LDH/NF with a high proportion of trivalent V ions(V3+), and then an enhanced intrinsic electrocatalytic HER activity. The HER testing results show that the in-NiVLDH/NF drives the current densities of 10 and 100 mA cm-2 at extremely low overpotentials of 114 and 245 mV without iR-compensation respectively, even outperforms commercial 20 wt% Pt/C at the large current density of over 80 mA cm-2 in alkaline media, as well as gives robust catalytic durability of at least 100 h in both alkaline and neutral media. More importantly, this work provides a fresh perspective for designing bimetal(oxy) hydroxides electrocatalysts with efficient hydrogen generation. | Danyang He Liyun Cao Jianfeng Huang Koji Kajiyoshi Jianpeng Wu Changcong Wang Qianqian Liu Dan Yang Liangliang Feng | 2020 | Journal of Energy Chemistry2020,29,8: | 5 |
| 5 | Effects of L-3-n-butylphthalide on caspase-3 and nuclear factor kappa-B expression in primary basal forebrain and hippocampal cultures after beta-amyloid peptide 1-42 treatment显示文摘BACKGROUND:L-3-n-butylphthalide(L-NBP) can inhibit phosphorylation of tau protein and reduce the neurotoxicity of beta-amyloid peptide 1-42(Aβ_(1-42)). OBJECTIVE:To observe the neuroprotective effects of L-NBP on caspase-3 and nuclear factor kappa-B(NF-κB) expression in a rat model of Alzheimer's disease. DESIGN,TIME AND SETTING:A cell experiment was performed at the Central Laboratory of Provincial Hospital affiliated to Shandong University between January 2008 and August 2008. MATERIALS:L-NBP(purity>98%) was provided by Shijiazhuang Pharma Group NBP Pharmaceutical Company Limited.Aβ_(1-42),3-[4,5-dimethylthiazolo-2]-2,5 iphenyltetrazolium bromide(MTT),and rabbit anti-Caspase-3 polyclonal antibody were provided by Cell Signaling, USA;goat anti-choactase and rabbit anti-NF-κB antibodies were provided by Santa Cruz,USA. METHODS:Primary cultures were generated from rat basal forebrain and hippocampal neurons at 17 or 19 days of gestation.The cells were assigned into five groups:the control group,the Aβ_(1-42) group(2μmol/ L),the Aβ_(1-42) + 0.1μmol/L L-NBP group,the Aβ_(1-42)+ 1μmol/L L-NBP group,and the Aβ_(1-42)+ 10μmol/L L-NBP group.The neurons were treated with Aβ_(1-42)(2μmol/L) alone or in combination with L-NBP(0.1,1,10μmol/L) for 48 hours.Cells in the control group were incubated in PBS. MAIN OUTCOME MEASURES:Morphologic changes were evaluated using inverted microscopy, viability using the MTT method,and the changes in caspase-3 and NF-κB expression using Western blot. RESULTS:Induction with Aβ_(1-42) for 48 hours caused cell death and soma atrophy,and increased caspase-3 and NF-κB expression(P<0.05).L-NBP blocked these changes in cell morphology, decreased caspase-3 and NF-κB expression(P<0.05),and improved cell viability,especially at the high dose(P<0.05). CONCLUSION:Aβ_(1-42) is toxic to basal forebrain and hippocampal primary neurons;L-NBP protects against this toxicity and inhibits the induction of caspase-3 and NF-κB expression. | Ruixia Wang Yong Zhang Liangliang Jiang Guozhao Ma Qingxi Fu Jialong Li Peng Yan Lunqian Shen Yabo Feng Chunxia Li Zaiying Pang Yuanxiao Cui Chunfu Chen Yifeng Du Zhaokong Liu | 2009 | Neural Regeneration Research2009,4,4: | 3 |
| 6 | Structural and biochemical studies of RIG-I antiviral signaling显示文摘Retinoic acid-inducible gene I(RIG-I)is an important pattern recognition receptor that detects viral RNA and triggers the production of type-I interferons through the downstream adaptor MAVS(also called IPS-1,CARDIF,or VISA).A series of structural studies have elaborated some of the mechanisms of dsRNA recognition and activation of RIG-I.Recent studies have proposed that K63-linked ubiquitination of,or unanchored K63-linked polyubiquitin binding to RIG-I positively regulates MAVS-mediated antiviral signaling.Conversely phos-phorylation of RIG-I appears to play an inhibitory role in controlling RIG-I antiviral signal transduction.Here we performed a combined structural and biochemical study to further define the regulatory features of RIG-I signaling.ATP and dsRNA binding triggered dimeriza-tion of RIG-I with conformational rearrangements of the tandem CARD domains.Full length RIG-I appeared to form a complex with dsRNA in a 2:2 molar ratio.Com-pared with the previously reported crystal structures of RIG-I in inactive state,our electron microscopic struc-ture of full length RIG-I in complex with blunt-ended dsRNA,for the first time,revealed an exposed active conformation of the CARD domains.Moreover,we found that purified recombinant RIG-I proteins could bind to the CARD domain of MAVS independently of dsRNA,while S8E and T170E phosphorylation-mimick-ing mutants of RIG-I were defective in binding E3 ligase TRIM25,unanchored K63-linked polyubiquitin,and MAVS regardless of dsRNA.These findings suggested that phosphorylation of RIG inhibited downstream signaling by impairing RIG-I binding with polyubiquitin and its interaction with MAVS. | Miao Feng Zhanyu Ding Liang Xu Liangliang Kong Wenjia Wang Shi Jiao Zhubing Shi Mark IGreene Yao Cong Zhaocai Zhou | 2013 | Protein & Cell2013,4,2: | 2 |
| 7 | The leaf extract of crofton weed(Eupatorium adenophorum)inhibits primary root growth by inducing cell death in maize root border cells显示文摘The extract of crofton weed(Eupatorium adenophorum) inhibits seed germination and weed growth;however,the physiological mechanisms underlying the effect of crofton weed extract on the modulation of seedling growth and root system development remain largely unclear.In this study,we investigated the effects of the leaf extract of crofton weed(LECW) on primary root(PR) growth in maize seedlings.Treatment with LECW markedly inhibited seed germination and seedling growth in a dose-dependent manner.Physiological analysis indicated that the LECW induced reactive oxygen species(ROS) accumulation in root tips,thereby leading to cell swelling and deformation both in the root cap and elongation zone of root tips,finally leading to cell death in root border cells(RBCs) and PR growth inhibition.The LECW also inhibited pectin methyl esterase(PME) activity,thereby decreasing the RBC number.Taken together,our results indicated that the LECW inhibited PR growth by inducing ROS accumulation and subsequent cell death in RBCs.The present study provides a better understanding of how the LECW modifies root system development and provides insight for evaluating the toxicity of crofton weed extracts in plants. | Jinhu Ma Xinxin Feng Xiaohuan Yang Yongheng Cao Weifeng Zhao Liangliang Sun | 2020 | Plant Diversity2020,42,3: | 2 |
| 8 | A versatile ligand-assisted cooperative template method to synthesize multi-shelled mesoporous hollow metal hydroxide and oxide nanospheres as catalytic reactors显示文摘Nowadays,multi-shelled mesoporous hollow metal oxide nanospheres have drawn a lot of attention due to their large internal space,nanometer scaled shell thickness,high specific surface area and well-defined mesopores,of which unique nanostructure endows metallic oxides with enhanced properties.In this thesis,we have studied and proposed a versatile ligand-assisted cooperative template method to synthesize multi-shelled mesoporous hollow metal hydroxides and oxides nanospheres,in which silica nanospheres act as sacrificial templates and the coordination interaction between metal ions and surfactant can be cooperatively amplified by using chelating ligand(ascorbic acid)as a co-template.The synthesized metal hydroxides and oxides nanospheres possess stable hollow structure,uniform spherical morphology and tunable diameter from 270 to 690 nm.All the multi-shelled mesoporous hollow metal hydroxide and metal oxide nanospheres exhibit high surface areas(up to 640 m^(2)/g).The obtained Au nanoparticles loaded composited nanospheres exhibit excellent reactivity for solvent-free aerobic oxidation of ethylbenzene with high activity(28.2%)and selectivity(87%). | Jingwei Liu Yali Ma Liangliang Zhang Yuenan Zheng Rui Zhang Ling Zhang Feng Wei Zhen-An Qiao | 2021 | Nano Research2021,14,9: | 2 |

| 15 | Activation of urchin-like Ni-doped W_(18)O_(49)/NF by electrochemical tuning for efficient water splitting显示文摘The electrochemical conversion is closely correlated with the electrocatalytic activities of the electrocatalyst.Herein,the urchin-like Ni-doped W_(18)O_(49)/NF with enriched active sites was prepared by solvothermal method followed by a low-temperature pyrolysis treatment was reported.Results demonstrate that the incorporation of Ni-doping triggers the lattice distortion of W_(18)O_(49) for the increasement of oxygen defects.Further,high-valent W^(6+)are partially reduced to low-valent W^(4+),wherein the electrons originate from the oxidation process of Ni^(2+)to Ni^(3+).The Ni^(3+)ions show an enhanced orbital overlap with the OER reaction intermediates.The generated W^(4+)ions contribute to release oxygen vacancies,eventually reorganizing Ni-doped W_(18)O_(49)/NF to unique electrochemical active species with a special amorphous-crystalline interface(AM/NiWO_x/NiOOH/NF).Simultaneously,the reconstruction results in an optimized valence band and conduction band.Eventually,the resultant AM/NiWO_x/NiOOH/NF with abundant active sites and improved oxidation/reduction capability exhibits more superior catalytic performance compared with the Ni-doped W_(18)O_(49)/NF counterpart.This study gives more insights in the electrochemical evolution of the tungsten-based oxide and provides effective strategies for optimizing the catalytic activity of materials with inherent hydrogen evolution reaction limitations. | Guojuan Hai Jianfeng Huang Liyun Cao Koji Kajiyoshi Long Wang Liangliang Feng Jun Chen | 2021 | Journal of Energy Chemistry2021,30,12: | 1 |

| 17 | Inhibition mechanisms of ammonia and sulfate in high-solids anaerobic digesters for food waste treatment: Microbial community and element distributions responses显示文摘The horizontal flow anaerobic digester indicated that high ammonia (2923 mg/L) and SO42-(3653 mg/L)would influence the performance of methane production with food waste as substrates.Therefore,bottle anaerobic digestion reactors were carried out to investigate the effect of ammonia/sulfate concentrations on the methane production.Experimental results manifested that the anaerobic digesters with an ammonia concentration of 3500 mg/L or sulfate of 1600 mg/L showed the best performance of methane production,with an average methane yield of 0.32 and 0.33 L (g VS)^(-1)d^(-1),respectively.Specifically,a higher ammonia (6500 mg/L) or sulfate (1600-3500 mg/L) level hindered the bioconversion of C from liquid to gas phase (2.68%or 1.73%CH_(4)-Gas,respectively),while insignificantly for the hydrolyzation of C and N from solid to liquid phase.Similar to sulfate,high ammonia nitrogen seriously inhibited the methanation process,leading to a significant carbon accumulation in the anaerobic reactor,especially for propionic acid.The predominant archaea Methanosarcina at genus level indicated that aceticlastic methanogenesis was the major methanogenic pathway.Meanwhile,high ammonia level suppressed the activity of Methanosarcina,while modest sulfate improved H_(2)-consuming methanogens activity.A large fraction of unclassified bacteria within the Firmicutes (43.78%-63.17%) and Bacteroidetes (24.20%-33.30%) phylum played an important role in substrates hydrolysis. | Likui Feng Weixin Zhao Yu Liu Yan Chen Shufei He Jing Ding Qingliang Zhao Liangliang Wei | 2023 | Chinese Chemical Letters2023,34,2: | 0 |
| 18 | 3-75 Radiosensitizing Effects of miR-185 on Melanoma Cells显示文摘Melanoma is an aggressive malignancy with high metastasis and low survival rate, of which the incidence rate keeps increasing year by year worldwide while the therapeutic options are still limited up to now[1;2]. Melanoma is considered to be a relatively radioresistant tumor, and radiotherapy has an important role in its treatment, especially in patients with central nervous system metastases[3], so enhancement of cellular radiosensitivity by radiosensitizer is an efficient strategy to improve the outcome of radiotherapy. | He Jinpeng Tian Ning Yang Yanli Jin Liangliang Feng Xiu Hua Junrui Lin Sulan Wang Bing Li He Wang Jufang | 2015 | IMP & HIRFL Annual Report2015,,1: | 0 |
| 19 | Extracellular polymeric substances-antibiotics interaction in activated sludge:A review显示文摘Antibiotics,the most frequently prescribed drugs,have been widely applied to prevent or cure human and veterinary diseases and have undoubtedly led to massive releases into sewer networks and wastewater treatment systems,a hotspot where the occurrence and transformation of antibiotic resistance take place.Extracellular polymeric substances(EPS),biopolymers secreted via microbial activity,play an important role in cell adhesion,nutrient retention,and toxicity resistance.However,the potential roles of sludge EPS related to the resistance and removal of antibiotics are still unclear.This work summarizes the composition and physicochemical characteristics of state-of-the-art microbial EPS,highlights the critical role of EPS in antibiotics removal,evaluates their defense performances under different antibiotics exposures,and analyzes the typical factors that could affect the sorption and biotransformation behavior of antibiotics.Next,interactions between microbial EPS and antibiotic resistance genes are analyzed.Future perspectives,especially the engineering application of microbial EPS for antibiotics toxicity detection and defense,are also emphatically stressed. | Weixin Zhao Jia You Shilei Yin Haizhou Yang Shufei He Likui Feng Jianju Li Qingliang Zhao Liangliang Wei | 2023 | Environmental Science and Ecotechnology2023,,1: | 0 |
| 20 | The cotton mitochondrial chimeric gene orf610a causes male sterility by disturbing the dynamic balance of ATP synthesis and ROS burst显示文摘Plant cytoplasmic male sterility(CMS)is maternally inherited and often manifested as aborted pollen development,but the molecular basis of abortion remains to be identified.To facilitate an investigation of CMS in cotton,the complete sequence of cotton mitochondrial(mt)genome for CMS-D2 line ZBA was determined.The mt genome was assembled as a single circular molecule with 634,036 bp in length.A total of 194 ORFs,36 protein-coding genes,six r RNAs,and 24 t RNAs were identified.Several chimeric genes encoding hypothetical proteins with transmembrane domains were identified.Among them,a previously unknown chimeric gene,orf610a,which is composed of atp1 and a 485-bp downstream sequence of unknown nature,was identified.RT-PCR and q RT-PCR validation indicated that orf610a was expressed specifically in a sterile line.Ectopic expression of orf610a in yeast resulted in excessive accumulation of reactive oxygen species and reduction in ATP content,in addition to inhibition of cellular growth.Transgenic A.thaliana overexpressing orf610a fused with a mitochondrial targeting peptide displayed partial male sterility.Interaction between ORF610a and the nuclear-encoded protein RD22 indicated an association between ORF610a and pollen abortion.Positive feedback during transcriptional regulation between nuclear regulatory factors and the mt CMS gene may account for the male sterility of ZBA. | Yongjie Zhang Yang Han Meng Zhang Xuexian Zhang Liping Guo Tingxiang Qi Yongqi Li Juanjuan Feng Hailin Wang Huini Tang Xiuqin Qiao Liangliang Chen Xiatong Song Chaozhu Xing Jianyong Wu | 2022 | The Crop Journal2022,10,6: | 0 |
