| 1 | Adsorptive removal of phosphate by the bimetallic hydroxide nanocomposites embedded in pomegranate peel显示文摘This study aimed to fabricate new and effective material for the efficiency of phosphate adsorption.Two types of adsorbent materials,the zirconium hydroxides embedded in pomegranate peel(Zr/Peel)and zirconium-lanthanum hydroxides embedded in pomegranate peel(Zr-La/Peel)were developed.Scanning electronic microscopy(SEM),x-ray photoelectron spectroscopy(XPS)and x-ray diffraction(XRD)were evaluated to give insight into the physicochemical properties of these adsorbents.Zr-La/Peel exceeded the adsorption efficiency of Zr/Peel adsorbents in batch adsorption experiments at the same pH level.The peel as a host can strive to have a strong'shielding effect'to increase the steadiness of the entrenched Zr and La elements.La and Zr are hydroxide metals that emit many hydrogen ions during the hydrolysis reaction,which contribute to protonation and electrostatic attraction.The highest adsorption capacity of La-Zr/Peel for phosphate was calculated to be40.21 mg/g,and pseudo second-order equation is very well fitted for kinetic adsorption.Phosphate adsorption efficiency was reduced by an increase of pH.With the background of coexisting Cl-,little effect on adsorption efficiency was observed,while adsorption capacities were reduced by almost 20-30%with the coexistence of SO42-,NO3-and humic acid(HA). | Muhammad Akram Xing Xu Baoyu Gao Qinyan Yue Shang Yanan Rizwan Khan Muhammad Ali Inam | 2020 | Journal of Environmental Sciences2020，32，5： | 8 |
| 2 | Effects of medicinal plants on Alzheimer's disease and memory deficits显示文摘Alzheimer's disease is an age-related neurodegenerative disorder characterized by memory deficits. Various studies have been carried out to find therapeutic approaches for Alzheimer's disease. However, the proper treatment option is still not available. There is no cure for Alzheimer's disease, but symptomatic treatment may improve the memory and other dementia related problems. Traditional medicine is practiced worldwide as memory enhancer since ancient times. Natural therapy including herbs and medicinal plants has been used in the treatment of memory deficits such as dementia, amnesia, as well as Alzheimer's disease since a long time. Medicinal plants have been used in different systems of medicine, particularly Unani system of medicines and exhibited their powerful roles in the management and cure of memory disorders. Most of herbs and plants have been chemically evaluated and their efficacy has also been proven in clinical trials. However, the underlying mechanisms of actions are still on the way. In this paper, we have reviewed the role of different medicinal plants that play an important role in the treatment of Alzheimer's disease and memory deficits using conventional herbal therapy. | Muhammad Akram Allah Nawaz | 2017 | Neural Regeneration Research2017，12，4： | 7 |
| 3 | A gelatin-based artificial SEI for lithium deposition regulation and polysulfide shuttle suppression in lithium-sulfur batteries显示文摘Lithium-sulfur(Li-S) battery is one of the best candidates for the next-generation energy storage system due to its high theoretical capacity(1675 mA h-1),low cost and environment friendliness.However,lithium(Li) dendrites formation and polysulfide shuttle effect are two major challenges that limit the commercialization of Li-S batteries.Here we design a facile bifunctional interlayer of gelatin-based fibers(GFs),aiming to protect the Li anode surface from the dendrites growth and also hinder the polysulfide shuttle effect.We reveal that the 3D structural network of GFs layer with abundant polar sites helps to homogenize Li-ion flux,leading to uniform Li-ion deposition.Meanwhile,the polar moieties also immobilize the lithium polysulfides and protect the Li metal from the side-reaction.As a result,the anodeprotected batteries have shown significantly enhanced performance.A high coulombic efficiency of 96% after 160 cycles has been achieved in the Li-Cu half cells.The Li-Li symmetric cells exhibit a prolonged lifespan for 800 h with voltage hysteresis(10 mV).With the as-prepared GFs layer,the Li-S battery shows approximately 14% higher capacity retention than the pristine battery at 0.5 C after 100 cycles.Our work presents that this gelatin-based bi-functional interlayer provides a viable strategy for the manufacturing of advanced Li-S batteries. | Naseem Akhtar Xiaogang Sun Muhammad Yasir Akram Fakhar Zaman Weikun Wang Anbang Wang Long Chen Hao Zhang Yuepeng Guan Yaqin Huang | 2021 | Journal of Energy Chemistry2021，30，1： | 5 |
| 4 | An efficient method for clonal propagation and in vitro establishment of softwood shoots from epicormic buds of teak(Tectona grandis L.)显示文摘Softwood shoots were produced from 40 cm long stem segments placed horizontally in flat trays containing sterilized sand under natural light or shade conditions for subsequent rooting and micropropagation studies in teak(Tectona grandis L.) . Higher number of shoots(6.17) per log was produced under natural light as compared to shade conditions. Forcing was also better in natural light as compared to shade in terms of shoot length,number of nodes or leaves. For rooting,2-4 cm long softwood shoots were excised and treated with either indole-3-butyric acid(IBA) or α-naphthyl acetic acid(NAA) at 0,1000,2000 or 3000 μmol·L-1 each or with combinations(1000 + 1000,2000 + 2000 or 3000 + 3000 μmol·L-1) and then placed in flat trays containing autoclaved sand at 25 ± 2oC in 16 h photoperiod at 35 μmol·m-2·s-1. After 28 days,softwood cuttings treated with IBA + NAA(3000 + 3000 μmol·L-1) had highest rooting percentage(89.3%) with 5.5 mean roots. Shoot apex and nodal explants of softwood cuttings were pretreated with 0.1%(w/v) ascorbic acid,boric acid,activated charcoal,citric acid,glutamine or polyvinylpolypyrollidone(PVP) for 24 h to remove phenolic compounds before surface disinfestation. Glutamine(Gl) and PVP were equally effective resulting in 60% establishment of shoot apices on MS medium supplemented with 10 μmol·L-1 6-benzylaminopurine(BAP) + 5 μmol·L-1 NAA. Using shoot apices,highest(42.80) number of multiple shoots with 54.33 mm shoot length were obtained on MS + BAP(8.8 μmol·L-1) + IBA(2 μmol·L-1) after 45 days. Shoots were successfully rooted and acclimatized to greenhouse conditions. | Muhammad AKRAM Faheem AFTAB | 2009 | Forestry Studies in China2009，11，2： | 3 |
| 5 | Establishment of Embryogenic Cultures and Efficient Plant Regeneration System from Explants of Forced Softwood Shoots of Teak (Tectona grandis L.)显示文摘The present study highlights an efficient plant regeneration system in teak(Tectona grandis L.) using forced softwood shoots as an initial plant material. Forced softwood shoots of teak were cut to prepare shoot tip, nodal and internodal explants and cultured on Murashige and Skoog(MS) medium + NAA(1, 3, 6, 10, and 15 μmol · L-1) or TDZ(0.001, 0.01, 0.1, 1, 4, 8, 10, 12 μmol · L-1) for callus induction. Such calluses were further grown on the same levels of TDZ or 0.4, 1, 4, 8, 10 μmol · L-1 BA + 1 μmol · L-1 IBA or GA3. Callus induction was the highest with4.55 cm3 callus volume and 5.75 g dry weight at 0.1 μmol · L-1 TDZ from shoot tips after 35 days. Embryogenic calluses were then shifted to 6, 8 or12 μmol · L-1 TDZ + 2 μmol · L-1 BA or IBA along with 5 mmol · L-1 ascorbic acid(AA) for shoot regeneration from embryogenic cultures. The highest embryogenesis(100%) with 36.4 globular and 5.5 heart-shaped embryo-like structures was obtained at 8 μmol · L-1 TDZ + 2 μmol · L-1 BA after 63 days. Such cultures when further maintained on the same medium up to 150 days resulted in 100% shoot regeneration with 16.4 mean shoots.Shoots were elongated up to 50 mm on agar medium + 8 μmol · L-1 BA + 1 μmol · L-1 GA3. An efficient rooting response(70%) was achieved having4.50 mean number and 49.10 mm root length at 8 μmol · L-1 IBA + 8 μmol · L-1 NAA + 0.1% activated charcoal after 36 days. Rooted shoots were acclimatized in glasshouse, achieving 56.6% plantlet survival. | Muhammad Akram Faheem Aftab | 2016 | Horticultural Plant Journal2016，2，5： | 3 |

| 7 | High Refractive Index Ti3O5 Films for Dielectric Metasurfaces显示文摘Ti_3 O_5 films are deposited with the help of an electron beam evaporator for their applications in metasurfaces.The film of subwavelength(632 nm) thickness is deposited on a silicon substrate and annealed at 400°C. The ellipsometr.y result shows a high refractive index above 2.5 with the minimum absorption coefficient in the visible region, which is necessary for high efficiency of transparent metasurfaces. Atomic force microscopy analysis is employed to measure the roughness of the as-deposited films. It is seen from micrographs that the deposited films are very smooth with the minimum roughness to prevent scattering and absorption losses for metasurface devices. The absence of grains and cracks can be seen by scanning electron microscope analysis, which is favorable for electron beam lithography. Fourier transform infrared spectroscopy reveals the transmission and reflection obtained from the film deposited on glass substrates. The as-deposited film shows high transmission above 60%,whieh is in good agreement with metasurfaces. | Sohail Abdul Jalil Mahreen Akram Gwanho Yoon Ayesha Khalid Dasol Lee Niloufar Raeis-Hosseini Sunae So Inki Kim Qazi Salman Ahmed Junsuk Rho Muhammad Qasim Mehmoo | 2017 | Chinese Physics Letters2017，34，8： | 2 |

| 19 | Breeding for pre-harvest sprouting resistance in bread wheat under rainfed conditions显示文摘Pre-harvest sprouting in wheat is the germination of seeds within the spikes when rains occur after or during grain ripening, which occurs commonly in the barani tract of Pakistan. Therefore, 10 cultivars and five advanced lines of spring bread wheat were evaluated for pre-harvest sprouting resistance. After natural rainfall,seeds were immediately collected from the wet spikes and tested for germinating ability. Three different germination tests were applied to hand-threshed seed:(1) spikes threshed on the day of sampling and germination tested immediately,(2) spikes threshed on the day of sampling and germination tested 1 week later, and(3) spikes threshed 1 week after sampling and germination test immediately after threshing. Seeds and spikes kept for 1 week were place on blotting paper at room temperature.Cultivars BARS-09, 09 FJ17, Doukkala-12, NARC-09 and Ouassou-20 exhibited higher sprouting resistance while other genotypes were susceptible to pre-harvest sprouting in each of the three tests. A diallel crossing was conducted with six susceptible and two resistant genotypes to assess the genetic behavior of pre-harvest sprouting resistance.The combining ability(CA) demonstrated a higher proportion of additive genetic effects for sprouting resistance, because of higher variance of general and specific CA for both parameters under study. Doukkala-12 and BARS-09 showed increased pre-harvest sprouting resistance in their F1 descendants. | Muhammad ZEESHAN Waheed ARSHAD Muhammad Imran KHAN Shiraz ALI Ali NAWAZ Amina BATOOL Muhammad TARIQ Muhammad Imran AKRAM Muhammad Amjad ALI | 2018 | Frontiers of Agricultural Science and Engineering2018，5，2： | 1 |
