1Highly Efficient Adsorption of Copper Ions by a PVP-Reduced Graphene Oxide Based On a New Adsorptions Mechanism显示文摘Polyvinylpyrrolidone-reduced graphene oxide was prepared by modified hummers method and was used as adsorbent for removing Cu ions from wastewater. The effects of contact time and ions concentration on adsorption capacity were examined. The maximum adsorption capacity of 1689 mg/g was observed at an initial p H value of 3.5 after agitating for 10 min. It was demonstrated that polyvinylpyrrolidone-reduced graphene oxide had a huge adsorption capacity for Cu ions, which was 10 times higher than maximal value reported in previous works. The adsorption mechanism was also discussed by density functional theory. It demonstrates that Cu ions are attracted to surface of reduced graphene oxide by C atoms in reduced graphene oxide modified by polyvinylpyrrolidone through physisorption processes, which may be responsible for the higher adsorption capacity. Our results suggest that polyvinylpyrrolidone-reduced graphene oxide is an effective adsorbent for removing Cu ions in wastewater. It also provides a new way to improve the adsorption capacity of reduced graphene oxide for dealing with the heavy metal ion in wastewater.Yongji Zhang HuiJuan Chi WenHui Zhang Youyi Sun Qing Liang Yu Gu Riya Jing 2014Nano-Micro Letters2014,6,1:9
2Short-Term Responses of Nitrous Oxide Emissions and Concentration Profiles to Fertilization and Irrigation in Greenhouse Vegetable Cultivation显示文摘In vegetable cultivation, the majority of N2O emissions occur after fertilization; it is therefore important to understand any factors contributing to this process. An experiment was conducted to investigate short-term N2O dynamics following topdressing in a greenhouse vegetable field in South China. During two topdressing processes, three different urea-N treatments with irrigation were conducted in May and June in a tomato (Lycopersicum esculentum) cultivation. The N2O fluxes, soil concentration profiles and soil environments at the 0-60 cm depths at 10 cm intervals were measured both immediately prior to and 5 days after topdressing. The N2O fluxes before topdressing ranged from 6.7±2.1 to 55.0±28.8 μ g N m 2 h 1 ; even higher numbers were recorded in highly fertilized plots. The NO3-N accumulation in the soil caused by vegetable cultivation during the 5 years prior to the start of the experiment, resulted in high background N2O fluxes. One day after topdressing (1 DAT) in May and June, N2O fluxes increased, which coincided with sharp increases in soil N2O concentrations at depths of 2.5 and 15 cm and in NO3-N and NH+4 -N contents at depths of 0-20 cm. From 1 to 5 DAT, fluctuations in the N2O fluxes did not harmonize with the N2O concentrations at a depth of 2.5 cm, which was attributed to different gas diffusion rates at depths of 0-10 cm. These results suggested that surface soil N and environmental conditions were crucial for determining the short-term N2O ebullitions during topdressing in greenhouse vegetable cultivation.S.

3Virtual preoperative planning and 3D printing are valuable for the management of complex orthopaedic trauma显示文摘Purpose:The technology of 3D printing(3DP)exists for quite some time,but it is still not utilized to its full potential in the field of orthopaedics and traumatology,such as underestimating its worth in virtual preoperative planning(VPP)and designing various models,templates,and jigs.It can be a significant tool in the reduction of surgical morbidity and better surgical outcome avoiding various associated complications.Methods:An observational study was done including 91 cases of complex trauma presented in our institution requiring operative fixation.Virtual preoperative planning and 3DP were used in the management of these fractures.Surgeons managing these cases were given a set of questionnaire and responses were recorded and assessed as a quantitative data.Results:In all the 91 cases,where VPP and 3DP were used,the surgeons were satisfied with the outcome which they got intraoperatively and postoperatively.Surgical time was reduced,with a better outcome.Three dimensional models of complex fracture were helpful in understanding the anatomy and sketching out the plans for optimum reduction and fixation.The average score of the questionnaire was 4.5,out of a maximum of 6,suggesting a positive role of 3DP in orthopaedics.Conclusion:3DP is useful in complex trauma management by accurate reduction and placement of implants,reduction of surgical time and with a better outcome.Although there is an initial learning curve to understand and execute the VPP and 3DP,these become easier with practice and experience.Abhishek Mishra Tarun Verma Abhishek Vaish Riya Vaish Raju Vaishya Lalit Maini 2019Chinese Journal of Traumatology2019,22,6:7

10Correlation of human immunodeficiency virus and antiretroviral therapy with cardiac disorders显示文摘The occurrence of cardiovascular illness in the human immunodeficiency virus(HIV)community is increasing,with a particular focus on coronary heart disease.Patients infected with HIV have a higher risk of myocardial infarction compared to the general population in modern countries due to the development of effective antiretroviral medications and increased life expectancy.Those not receiving highly active antiretroviral therapy(ART)may experience common cardiac consequences,including myocarditis,dilated cardiomyopathy,endocarditis,pulmonary hypertension,pericardial effusion,and cardiotoxicity associated with non-antiretroviral drugs.After the use of highly active ART,continuing immune activation and systemic inflammation seem to play a central role in this process.Recent studies suggest that protease inhibitors might negatively impact the progression of HIV-related heart failure(HF),which complicates the determination of the best therapy strategy for HIVassociated cardiomyopathy.The objective of this review is to examine the pathophysiology and correlation of various antiretroviral drugs leading to HIV-associated HF.Additionally,we explore the causes of HIV-associated atherosclerotic cardiovascular disease,including the high frequency of classic cardiovascular risk factors in HIVinfected patients,as well as HIV-related factors like the use of ART and chronic inflammation despite successful treatment of HIV infection.Numerous studies have revealed that individuals living with HIV/acquired immune deficiency syndrome frequently experience HF.In conclusion,despite advancements in HIV care,HIV-infected individuals continue to face an increased risk of HIV-associated cardiomyopathy and atherosclerosis.Further research is necessary to comprehend the underlying causes and develop effective treatments for cardiovascular disease in this population.We also discuss the currently available therapeutic options and ongoing research to mitigate the risk of cardiovascular disease and inflammation in HIV-infected individuals.Riya Sharma Mandeep kaur 2023Global Health Journal2023,7,3:1

13Laser-induced thermal lens study of the role of morphology and hydroxyl group in the evolution of thermal diffusivity of copper oxide显示文摘The paper explores the evolution of thermal behavior of the material by studying the variations in thermal diffusivity using the single beam thermal lens(TL) technique. For this purpose, the decomposition of Cu(OH)_(2) into CuO is studied in a time range up to 120 h, by subjecting the sample to morphological, structural, and spectroscopic characterizations. The time evolution of thermal diffusivity can be divided into three regions for demonstrating the dynamics of the reaction. When the reaction is complete, the thermal diffusivity is also found to be saturated. In addition to the morphological modifications,from rods to flakes, the variations in the amount of hydroxyl group are attributed to be responsible for the enhancement of base fluid's thermal diffusivity by 165%. Thus the study unveils the role of hydroxyl groups in the thermal behavior of CuO.Riya Sebastian M S Swapna Vimal Raj S Sankararaman 2021Chinese Physics B2021,30,6:1
