5Detailed investigation of optimized alkali catalyzed transesterification of Jatropha oil for biodiesel production显示文摘The non-edible oils are believed to be one of the major feedstock for the production of biodiesel in future.In the present study,we investigated the production of Jatropha oil methyl esters(JOMEs) via alkali-catalyzed transesterification route.The biophysical characteristics of Jatropha oil were found within the optimal range in accordance with ASTM standards as a substitute diesel fuel.The chemical composition and production yield of as-synthesized biodiesel were confirmed by various analytical techniques such as FT-IR,1H NMR,13 C NMR and gas chromatography coupled with mass spectrometry.A high percentage conversion,~96.09%,of fatty acids into esters was achieved under optimized transesterification conditions with 6 :1 oil to methanol ratio and 0.9 wt% Na OH for 50 min at ~60°C.Moreover,twelve fatty acids methyl esters(FAME) were quantified in the GC/MS analysis and it was interesting to note that the mass fragmentation pattern of saturated,monounsaturated and diunsaturated FAME was comparable with the literature reported values.Waqas Ahmed Muhammad Faizan Nazar Syed Danish Ali Usman Ali Rana Salah Ud-Din Khan 2015Journal of Energy Chemistry2015,24,3:5
6乳酸菌协同小麦胚芽油发酵对黑曲霉生长活性的影响显示文摘本文通过初筛和复筛考察不同乳酸菌的抗真菌活性,并将小麦胚芽油添加入乳酸菌培养液中进行发酵,旨在明确乳酸菌协同小麦胚芽油发酵对抗黑曲霉活性的影响。研究表明,小麦胚芽油不具有抑制黑曲霉生长的能力,而乳杆菌LF5发酵液抑菌率随着小麦胚芽油浓度的升高明显提升,且该现象具有菌株特异性。通过加热、中和pH、添加蛋白酶及过氧化氢酶发现,乳酸菌协同发酵上清液中的抗真菌活性物质主要由有机酸以及部分具有良好热稳定性的非蛋白类组分组成。此外,采用乳杆菌LF5协同小麦胚芽油发酵制备面包,在第5 d发现肉眼可见霉菌,与空白组(第2~3 d)相较具有显著抑制黑曲霉生长活性的作用,为乳酸菌在发酵米面食品中的应用提供了新的方向。史梦洁 闫博文 Faizan Ahmed Sadiq 范大明 连惠章 田丰伟 赵建新 张灏 陈卫 2020食品工业科技2020,41,19:3
7Molecular docking studies of anti-cancerous candidates in Hippophae rhamnoides and Hippophae salicifolia显示文摘Actinorhizal plants contain numerous antioxidants that may play a crucial role in preventing the formation of tumors.H-Ras p21,a member of the Ras-GTPase family,is a promising target to treat various kinds of cancers.An in silico docking study was carried out to identify the inhibitory potential of compounds of these plants against H-Ras by using Discovery Studio 3.5 and by using Autodock 4.2.Docking studies revealed that four compounds,isorhamnetin-7-rhamnoside,quercetin-3-glucoside-7-rhamnoside(present in H.rhamnoides),zeaxanthin,and translutein(present in H.salicifolia) significantly bind with binding energies-17.1534,-14.7936,-10.2105 and-17.2217 Kcal/mol,respectively,even though they slightly deviate from Lipinski's rule.Absorption,distribution,metabolism,excretion and toxicity(ADME/tox) analyses of these compounds and their stereoisomers showed that they were less toxic and non-mutagenic.Amongst them,isorhamntein-7-rhamnoside showed hepatotoxicity.Hence,these compounds can be further investigated in vivo to optimize their formulation and concentration and to develop potential chemical entities for the prevention and treatment of cancers.Talambedu Usha Sushil Kumar Middha Arvind Kumar Goyal Mahesh Karthik DA Manoj Syed Faizan Peyush Goyal HP Prashanth Veena Pande 2014The Journal of Biomedical Research2014,28,5:3
8Loan growth and bank solvency:evidence from the Pakistani banking sector显示文摘Background:The dramatic loan growth and changes in the Pakistani banking system in mid-2000s have led to significant research attention on borrowers and lenders.This expansion and diversification in financial sector was driven by structural reforms,political stability and significant economic growth.Against this background,this study investigates the loan growth and risk-taking behavior of the banks during the expansionary periods of lending.Method:This study used dynamic two-step system generalized method of moment’s estimation technique,based on data taken from 32 banks in Pakistan over 2006-2014.Result:Loan growth has a significant effect on bank-specific and macroeconomicspecific variables.Loan growth in the previous year raises non-performing loans and decreases the solvency of banks with a time lag of many years.The driving force behind this phenomenon is weak prudential regulation among competitors,the asymmetric information of the borrowers,and,most importantly,that banks underestimate the risk of lending during credit booms.Conclusion:More regulatory measures are required to ensure a strong financial system when the volume of non-performing loan grows significantly.An increase in the capital requirement policy for rapidly growing banks is also needed because the problem of abnormal loan growth cannot be detected at the current time.At the same time,strong supervision is necessary to avoid the adverse consequences of borrower selection.Muhammad Kashif Syed Faizan Iftikhar Khurram Iftikhar 2016Financial Innovation2016,2,1:2

10Changes in Growth,Photosynthetic Pigments,Cell Viability,Lipid Peroxidation and Antioxidant Defense System in Two Varieties of Chickpea(Cicer arietinum L.)Subjected to Salinity Stress显示文摘Salinity is one of the most severe abiotic stresses for crop production.The present study investigates the salinityinduced modulation in growth indicators,morphology and movement of stomata,photosynthetic pigments,activity of carbonic anhydrase as well as nitrate reductase,and antioxidant systems in two varieties of chickpea(Pusa-BG5023,and Pusa-BGD72).On 20^(th) day of sowing,plants were treated with varying levels of NaCl(0,50,100,150 and 200 mM)followed by sampling on 45 days of sowing.Recorded observations on both the varieties reveal that salt stress leads to a significant decline in growth,dry biomass,leaf area,photosynthetic pigments,protein content,stomatal behavior,cell viability,activity of nitrate reductase and carbonic anhydrase with the rise in the concentration of salt.However,quantitatively these changes were less in Pusa-BG5023 as compared to Pusa-BGD72.Furthermore,salinity-induced oxidative stress enhanced malondialdehyde content,superoxide radicals,foliar proline content,and the enzymatic activities of superoxide dismutase,catalase,and peroxidase.The variety Pusa-BGD72 was found more sensitive than Pusa-BG5023 to salt stress.Out of different graded concentrations(50,100,150 and 200 mM)of sodium chloride,50 mM was least toxic,and 200 mM was most damaging.The differential behavior of these two varieties measured in terms of stomatal behavior,cell viability,photosynthetic pigments,and antioxidant defense system can be used as prospective indicators for selection of chickpea plants for salt tolerance and sensitivity.Zeenat Mushtaq Shahla Faizan Basit Gulzar Humira Mushtaq Sayyada Bushra Alisha Hussain Khalid Rehman Hakeem 2022Phyton-International Journal of Experimental Botany2022,91,1:1

12Exploration of B-site alloying in partially reducing Pb toxicity and regulating thermodynamic stability and electronic properties of halide perovskites显示文摘Alloying strategies provide a high degree of freedom for reducing lead toxicity,improving thermodynamic stability, tuning the optoelectronic properties of ABX3 halide perovskites by varying the alloying element species and their contents.Given the key role of B-site cations in contributing band edge states and modulating structure factors in halide perovskites,the partial replacement of Pb2+with different B-site metal ions has been proposed.Although several experimental attempts have been made to date,the effect of B-site alloying on the stability and electronic properties of halide perovskites has not been fully explored.Herein,we take cubic CsPbBr3 perovskite as the prototype material and systematically explore the effects of B-site alloying on Pb-containing perovskites.According to the presence or absence of the corresponding perovskite phase,the ten alloying elements investigated are classified into three types(i.e.,Type Ⅰ:Sn Ge,Ca,Sr;Type Ⅱ:Cd,Mg,Mn;Type Ⅲ:Ba,Zn,Cu).Based on the first-principles calculations,we obtain the following conclusions.First,these B-site alloys will exist as disordered solid solutions rather than ordered structures at room temperature throughout the composition space.Second,the alloying of Sn and Ge enhances the thermodynamic stability of the cubic perovskite host,whereas the alloying of the other elements has no remarkable effect on the thermodynamic stability of the cubic perovskite host.Third,the underlying physical mechanism for bandgap tuning can be attributed to the atomic orbital energy mismatch or quantum confinement effect.Fourth,the alloying of different elements demonstrates the diversity in the regulation of crystal structure and electronic properties,indicating potential applications in photovoltaic s and self-trapped exciton-based light-emitting applications.Our work provides theoretical guidance for using alloying strategies to reduce lead toxicity,enhance stability,and optimize the electronic properties of halide perovskites to meet the needs of optoelectronic applications.Xinjiang Wang Muhammad Faizan Kun Zhou Hongshuai Zou Qiaoling Xu Yuhao Fu Lijun Zhang 2023Science China(Physics,Mechanics & Astronomy)2023,66,3:1

14Lightweight authentication protocol for e-health clouds in IoT-based applications through 5G technology显示文摘Modem information technology has been utilized progressively to store and distribute a large amount of healthcare data to reduce costs and improve medical facilities.In this context,the emergence of e-Health clouds offers novel opportunities,like easy and remote accessibility of medical data.However,this achievement produces plenty of new risks and challenges like how to provide integrity,security,and confidentiality to the highly susceptible e-Health data.Among these challenges,authentication is a major issue that ensures that the susceptible medical data in clouds is not available to illegal participants.The smart card,password and biometrics are three factors of authentication which fulfill the requirement of giving high security.Numerous three-factor ECC-based authentication protocols on e-Health clouds have been presented so far.However,most of the protocols have serious security flaws and produce high computation and communication overheads.Therefore,we introduce a novel protocol for the e-Health cloud,which thwarts some major attacks,such as user anonymity,offline password guessing,impersonation,and stolen smart card attacks.Moreover,we evaluate our protocol through formal security analysis using the Random Oracle Model(ROM).The analysis shows that our proposed protocol is more efficient than many existing protocols in terms of computation and communication costs.Thus,our proposed protocol is proved to be more efficient,robust and secure.Minahil Muhammad Faizan Ayub Khalid Mahmood Saru Kumari Arun Kumar Sangaiah 2021Digital Communications and Networks2021,7,2:1
