A matrix of LiNi 0.5 Mn 0.3 Co 0.2 O 2 /graphite cells filled with 1.33 molal LiPF 6 in EC:EMC:DMC (ethylene carbonate: ethyl methyl dimethyl carbonate) (25:5:70 by volume) electrolyte and different weight percentages vinylene carbonate (VC) ethylene sulfate (DTD) additives underwent prolonged charge-discharge cycling at 20 °C 40 °C. The volume gas produced during formation cycle testing was me...

this paper is mainly focusing on the determination of mean molal activity coefficient of hcl in aqueous acidic medium. the present investigations have been carried out to determine the activity coefficients of hydrochloric acid in 2-propanol water mixture solutions under various conditions to study the ion solvent interactions in different temperatures. the standard molar potential em0 of the c...

background the non-revenue water refers to a difference between the volume of water entering the system and billed authorized consumption. objectives the main purpose of this study is to determine the volume of non-revenue water in order to recognize the factors influencing water losses so that the information gathered can used in non-revenue water reduction management. materials and methods ka...

Rapid infusion of hyperosmolar solutions into the internal carotid artery transiently disrupts the blood-brain barrier, permitting entry of substances that are ordinarily excluded from the nervous system. This study compared gentamicin concentrations in the cerebrospinal fluid (CSF) and brain tissue of rabbits receiving intracarotid infusions of 2 molal mannitol with those in three groups of co...

The heat capacity of zinc ferrite (ZnFe,O,) has been determined over the range 5 to 350°K. Molal values of C~,S’, and HO-H,O computed from the thermal data are 32,99&t-0.03 cal/deg., 36.01 f0.03 cal/deg., and 18,00&0.02 Cal, respectively, at 298,lS”K. A co-operative thermal anomaly associated with antiferromagnetic ordering occurs at 9.5” and extends toward higher temperatures probably as a con...
