In this study,we have explored the use of water as a non-solvent for tuning the microstructure of poly-benzimidazole(PBI)membranes,which are potential separators for lithium metal batteries(LMBs).The traditional method for membrane synthesis called nonsolvent-induced phase separation(NIPS),usually relies on hazardous and costly organic *** dissolving sodium chloride(Nacl)in water,we could adjust the water ionic potency and the exchange speed of the non-solvent with the DMAC solution to change the micropore structure of the PBI *** increasing Nacl concentration,the micro-pores in the PBI membrane transitioned from finger-like to sponge-like *** to com-mercial separators like the Celgard separator,the PBI membrane with sponge-like micropores exhibited better regulation of lithium deposition and improved Li^(+) transportation capability due to its good wetta-bility with the ***,the PBI membrane-based Li/Li symmetric cell and Li/LiFePO_(4) full cell demonstrated superior performance compared to the Celgard-based *** research proposes an eco-friendly and scalable synthetic approach for fabricating commercial separators for LMBs,addressing the issue of lithium dendrite growth and improving overall battery safety and performance.

物理化学学报 2008年第7期24卷 1180-1184页

作者： KABIR-UD-DIN KHATOON Suraiya NAQVI andleeb Z Department of Chemistry Aligarh Muslim University

The effects of nonelectrolytes (ureas, amino acids, sugars) on the cloud point (CP) of nonionic surfactant Triton X-114 (TX-114) and tetra-n-butylammonium bromide (TBAB) system were studied. Ureas as well as thioureas increased the CP. Behaviors of amino acids depended upon their nature. Nonpolar and uncharged polar amino acids were less effective in changing the CP. However, tryptophan and phenylalanine increased the CP sharply. Acidic amino acid (aspartic acid) and sugars decreased the CP. The results were explained in terms of their effect on water structure. Amino acids got solubilized either in the micellar interior or in the bulk phase.

Hyperhomoysteinemia as a risk factor for coronary heart diseases in chronic hepatitis C patients

引用

World Journal of Cardiovascular Diseases 2013年第8期3卷 499-505页

作者： Ali Raza Kazmi andleeb Hanif Muhammad Ismail Javaria Qazi Department of Biotechnology Quaid-i-Azam University Islamabad Pakistan Institute of Biomedical and Genetic Engineering Islamabad Pakistan Institute of Biomedical and Genetic Engineering Islamabad Pakistan Department of Biotechnology Quaid-i-Azam University Islamabad Pakistan

Hepatitis C virus is one of the major health problems worldwide. It affects mainly the liver but several extrahepatic manifestations are also accounted. Chronic hepatitis C patients are at an increased risk of developing hepatic steatosis, which share many clinical features with the metabolic syndrome. Hepatic steatosis has also been associated with elevated levels of markers of inflammation such as homocysteine, identified as hyperhomocysteinemia (HHC). HHC due to Methylenetetrahydrofolate Reductase (MTHFR) gene, in particular the C677T polymorphism, was recently associated with coronary heart diseases (CHD) in chronic hepatitis C (CHC) patients. Homocysteine is an intermediate in methionine metabolism, which takes place mainly in the liver metabolism. Deficiencies of micronutrients (folate, vitamin B 6 and possibly vitamin B 12) along with mild hyperhomocysteinemia, perhaps, act synergistically with other classical risk factors to further increase the risk of CHD. Clinical data indicate that HHC is associated with an increased incidence of CHD as well as with the severity of the disease in CHC patients. In conclusion, HHC might be a potential aetiological factor of CHD in CHC patients. The aim of this review is to investigate the progression of coronary heart diseases in chronic hepatitis C patients and correlate with levels of homocysteine in concurrence to genetic defects and nutrient deficiencies. However, future studies need to clarify the mechanistic role of HHC in CHD and CHC as a useful paradigm with most interesting therapeutic implications.
