| 1 | The role and significance of Magnesium in modern day research-A review显示文摘Magnesium is one of the largely available elements in the earth’s crust. It has a low structural density with high specific strength. This unique material property has forced an increase in the use of magnesium and its alloys in various applications pertaining to industrial sector,automobiles, aerospace and biomedical. Since magnesium is a highly reactive metal, it is prone to higher rate of corrosion as compared to its counterparts. Thus, it is essential to analyze the corrosion behavior of magnesium and its alloys in its applications. An appropriate process is to be followed in the design and development of magnesium alloys which overcome the limitations of magnesium and enhance the desired material properties in accordance to their applications. This review paper summarizes the importance of magnesium and its material properties. The influence of various alloying elements on the mechanical properties of magnesium is reviewed. The broad classification of Mg alloys and their behavioral trends are detailed. The corrosion behavior of magnesium and the influence of corrosion products on the material characteristics of magnesium, in aqueous medium, are discussed. The manufacturing techniques of magnesium alloys along with the secondary techniques are also covered. The various applications and the limitations of magnesium in these applications are covered. A complete section is dedicated towards detailing the recent trends of magnesium(Mg) alloys, i.e., the biodegradable nature and applications of Mg alloys. The influence of biocorrosion on Mg alloys and techniques to overcome it have been deliberated. This paper provides a thorough review on recent developments of magnesium with respect to engineering applications. | S V Satya Prasad S B Prasad Kartikey Verma Raghvendra Kumar Mishra Vikas Kumar Subhash Singh | 2022 | Journal of Magnesium and Alloys2022，10，1： | 11 |
| 2 | Spectral absorption control of femtosecond laser-treated metals and application in solar-thermal devices显示文摘Direct femtosecond(fs)laser processing is a maskless fabrication technique that can effectively modify the optical,electrical,mechanical,and tribological properties of materials for a wide range of potential applications.However,the eventual implementation of fs-laser-treated surfaces in actual devices remains challenging because it is difficult to precisely control the surface properties.Previous studies of the morphological control of fs-laser-processed surfaces mostly focused on enhancing the uniformity of periodic microstructures.Here,guided by the plasmon hybridisation model,we control the morphology of surface nanostructures to obtain more control over spectral light absorption.We experimentally demonstrate spectral control of a variety of metals[copper(Cu),aluminium(Al),steel and tungsten(W)],resulting in the creation of broadband light absorbers and selective solar absorbers(SSAs).For the first time,we demonstrate that fs-laser-produced surfaces can be used as high-temperature SSAs.We show that a tungsten selective solar absorber(W-SSA)exhibits excellent performance as a high-temperature solar receiver.When integrated into a solar thermoelectric generation(TEG)device,W-SSA provides a 130%increase in solar TEG efficiency compared to untreated W,which is commonly used as an intrinsic selective light absorber. | Sohail A.Jalil Bo Lai Mohamed ElKabbash Jihua Zhang Erik M.Garcell Subhash Singh Chunlei Guo | 2020 | Light(Science & Applications)2020，9，1： | 4 |
| 3 | Decadal trends in precipitable water vapor over the Indus River Basin using ERA5 reanalysis data显示文摘Precipitable Water Vapor(PWV)constitutes a pivotal parameter within the domains of atmospheric science,and remote sensing due to its profound influence on Earth’s climate dynamics and weather patterns.It exerts a significant impact on atmospheric stability absorption and emission of radiation,thus engendering alterations in the Earth’s radiative equilibrium.As such,precise quantification of PWV holds the potential to enhance weather prognostication and fortify preparedness against severe meteorological phenomena.This study aimed to elucidate the spatial and temporal changes in seasonal and annual PWV across the Indus River Basin and its sub-basins using ERA5 reanalysis datasets.The present study used ERA5 PWV(entire atmospheric column),air temperature at 2 m(t2m)and 500 hPa(T_500hPa),evapotranspiration,and total cloud cover data from 1960 to 2021.Theil Sen slope estimator and Mann-Kendall test were used for trend analysis.Correlation and multiple regression methods were used to understand the association of PWV with other factors.The findings have unveiled the highest increase in mean PWV during the monsoon(0.40 mm/decade),followed by premonsoon(0.37 mm/decade),post-monsoon(0.27 mm/decade),and winter(0.19 mm/decade)throughout the study period.Additionally,the mean PWV exhibited the most pronounced positive trend in the sub-basin Lower Indus(LI),followed by Panjnad(P),Kabul(K),and Upper Indus(UI)across all seasons,except winter.Annual PWV has also risen in the Indus basin and its sub-basins over the last six decades.PWV exhibits a consistent upward trend up to an elevation of 3500 m within the basin which is most pronounced during the monsoon season,followed by the pre-monsoon.The escalating PWV within the basin is reasonably ascribed to increasing air temperatures,augmented evapotranspiration,and heightened cloud cover.These findings hold potential utility for pertinent authorities engaged in water resource management and planning. | Seema RANI Jyotsna SINGH Subhash SINGH Purushottam TIWARI Suraj MAL | 2023 | Journal of Mountain Science2023，20，10： | 1 |

| 5 | Thickness Dependent Physical Properties of Thermally Evaporated Nanocrystalline CdSe Thin Films显示文摘This paper presents a study on thickness dependent physical properties of cadmium selenide thin films. The films of thickness 445, 631 and 810 nm were deposited employing thermal evaporation technique on glass and ITO-coated glass substrates followed by thermal annealing in air atmosphere at 200 °C. These films were subjected to X-ray diffractometer, UV–Vis spectrophotometer, scanning electron microscopy(SEM) and electrometer for structural, optical,surface morphological and electrical analysis respectively. The structural analysis reveals that the films are nanocrystalline in nature with cubic phase and preferred orientation(111). The crystallographic parameters such as lattice constant, interplanar spacing, grain size, internal strain, dislocation density, number of crystallites per unit area and texture coefficient are calculated and discussed. The optical band gap is found in the range 1.75–1.92 e V and observed to increase with thickness.The SEM study shows that the annealed films are uniform, fully covered and well defined. The electrical analysis shows that the conductivity is varied with film thickness and found within the order of semiconductor behavior. | Anuradha Purohit Subhash Chander Satya Pal Nehra Mahendra Singh Dhaka | 2015 | Acta Metallurgica Sinica(English Letters)2015，28，10： | 1 |

| 13 | Chemical characteristics of trace metals in PM10 and their concentrated weighted trajectory analysis at Central Delhi,India显示文摘Trace metals associated with PM_(10) aerosols and their variation during day and nighttime as well as during different seasons have been studied for the year 2012. PCA analysis suggested5 PCs,which accounted for 86.8% cumulative variance. PC1 accounted for 30% with a significant loading of metals of anthropogenic origin,while PC2 showed 28% variance with the loading of metals of crustal origin. These trace metals showed seasonal distinct day and night time characteristics. The concentrations of Cu,Pb,and Cd were found to be higher during nighttime in all the seasons. Only Fe was observed with significantly higher mean concentrations during daytime of all seasons except monsoon. The highest mean values of Cu,Cd,Zn,and Pb during post-monsoon might be attributed to winds advection over the regions of waste/biomass burning and industrial activities in Punjab and Haryana regions.Furthermore,concentration weighted trajectory analysis suggested that metals of crustal origin were contributed by long-range transport while metals of anthropogenic and industrial activities were contributed by regional/local source regions. | Subhash Chandra Monika J.Kulshrestha Ruchi Singh Nahar Singh | 2017 | Journal of Environmental Sciences2017，29，5： | 1 |

| 16 | Degradation of platinum electrocatalysts for methanol oxidation by lead contamination显示文摘Platinum exhibits high electrocatalytic activity toward various reactions but might be poisoned by some species. This communication reports a new finding that the electrocatalytic activity of platinum for methanol oxidation will be largely lost in a lead-contaminated environment. This activity loss is demonstrated in an electrochemical cell using a lead counter electrode for measuring the activity of platinum electrode towards methanol oxidation. The recorded methanol oxidation current in this cell is significantly decreased compared with that using a platinum counter electrode. The possible mechanism is related to the adsorption of trace lead ions from the lead counter electrode, as confirmed by comparing the calculated binding energies of platinum and lead ions with oxygen ion. This report is of great importance for reliably designing and efficiently managing direct methanol fuel cells, because trace lead might be present in various components in the fuel cell systems or in air and attention should be paid to its negative effect. | Zihao Li Xianggui Zhou Subhash Singh Xiaoming Wei Chunlei Guo Weishan Li | 2023 | Chinese Chemical Letters2023，34，2： | 0 |
| 17 | Enhancement of Urinary Elimination of 3-Bromobenzanthrone Metabolites by Oral Supplementation of Ascorbic Acid in Guinea Pigs显示文摘Objective 3-Bromobenzanthrone (3-BBA), an anthraquinone intermediate dye, is extensively used in textile industry. Since, our prior studies have shown that 3-BBA caused significant depletion of ascorbic acid (AsA) levels, the effect of exogenous supplementation of AsA on the urinary elimination of 3-BBA metabolites was investigated. Method Guinea pigs were treated with single oral dose of 3-BBA (50 mg/kg b. wt.) in groundnut oil while another group was treated with single oral dose of 3-BBA (50 mg/kg b. wt.) along with 3 day prior and post oral supplementation of AsA. Control groups were either treated with groundnut oil or AsA alone. Urine from individual animals was collected, extracted and analysed on HPTLC. Results The highest elimination of 3-BBA (75 mg) was found to be in 0-24 h urine fraction which decreased to 18 mg and 5 mg in the two subsequent 24 hourly fractions of urine. Exogenous supplementation of AsA increased the total urinary elimination of 3-BBA by almost 77%. A total of 10 fluorescent metabolites excluding the parent compound were eliminated in the urine of guinea pigs treated with 3-BBA. Densitometric scanning of chromatogram showed different peaks at Rf 0.18, 0.22, 0.27, 0.34, 0.40, 0.48, 0.56, 0.66, 0.72, 0.80, and 0.95 which were eliminated and marked as urinary metabolite 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 11 respectively. AsA not only significantly enhanced the elimination of 3-BBA metabolites but also modified the pattern of metabolites drastically in 0-6 h, 6-24 h and 24-48 h urine fractions. Conclusion These results indicate that AsA may be useful in protecting the toxicity of 3-BBA by fascilitating the urinary metabolite(s) excretion of 3-BBA. | RAVINDRA P. SINGH RAJ KHANNA SUBHASH K.

| 18 | Radiation dose analysis of computed tomography coronary angiography in Children with Kawasaki disease显示文摘BACKGROUND There is evolving role of computed tomography coronary angiography(CTCA)in non-invasive evaluation of coronary artery abnormalities in children with Kawasaki disease(KD).Despite this,there is lack of data on radiation dose in this group of children undergoing CTCA.AIM To audit the radiation dose of CTCA in children with KD.METHODS Study(December 2013-February 2018)was performed on dual source CT scanner using adaptive prospective electrocardiography-triggering.The dose length product(DLP in milligray-centimeters-mGy.cm)was recorded.Effective radiation dose(millisieverts-mSv)was calculated by applying appropriate age adjusted conversion factors as per recommendations of International Commission on Radiological Protection.Radiation dose was compared across the groups(0-1,1-5,5-10,and>10 years).RESULTS Eighty-five children(71 boys,14 girls)with KD underwent CTCA.The median age was 5 years(range,2 mo-11 years).Median DLP and effective dose was 21 mGy.cm,interquartile ranges(IQR)=15(13,28)and 0.83 mSv,IQR=0.33(0.68,1.01)respectively.Mean DLP increased significantly across the age groups.Mean effective dose in infants(0.63 mSv)was significantly lower than the other age groups(1-5 years 0.85 mSv,5-10 years 1.04 mSv,and>10 years 1.38 mSv)(P<0.05).There was no significant difference in the effective dose between the other groups of children.All the CTCA studies were of diagnostic quality.No child required a repeat examination.CONCLUSION CTCA is feasible with submillisievert radiation dose in most children with KD.Thus,CTCA has the potential to be an important adjunctive imaging modality in children with KD. | Mahesh Chandra Bhatt Manphool Singhal Rakesh Kumar Pilania Subhash Chand Bansal Niranjan Khandelwal Pankaj Gupta Surjit Singh | 2023 | World Journal of Clinical Pediatrics2023，12，4： | 0 |
| 19 | Critical Update on the Diagnosis and Management of COVID-19 in Advanced Cirrhosis and Liver Transplant Recipients显示文摘The novel coronavirus disease 2019(COVID-19)pandemic has impacted health care worldwide,with specific patient populations,such as those with diabetes,cardiovascular disease,and chronic lung disease,at higher risk of infection and others at higher risk of disease progression.Patients with decompensated cirrhosis fall into the latter category and are a unique group that require specific treatment and management decisions because they can develop acute-on-chronic liver failure.In liver transplant recipients,the atypical immunity profile due to immunosuppression protects against downstream inflammatory responses triggered by COVID-19.This exhaustive review discusses the outcomes associated with COVID-19 in patients with advanced cirrhosis and in liver transplant recipients.We focus on the immunopathogenesis of COVID-19,its correlation with the pathogenesis of advanced liver disease,and the effect of immunosuppression in liver transplant recipients to provide insight into the outcomes of this unique patient population. | Cyriac Abby Philips Mohamed Rela Arvinder Singh Soin Subhash Gupta Sudhindran Surendran Philip Augustine | 2021 | Journal of Clinical and Translational Hepatology2021，9，6： | 0 |
