We show, for the first time, a redox-active electrolyte in combination with a polyaniline-coated curved graphene active material to achieve significant enhancement in the capacitance (36-92% increase) compared to supercapacitors that lack the redox-active contribution from the electrolyte. The supercapacitors based on the redox-active electrolyte also exhibit excellent rate capability and very ...

INTRODUCTION Month of Ramadan bring many changes in life style, especially the diet of Muslims all over the world among both fasting and nonfasting individuals. Hemodialysis patients are kept on restricted diet because of fluid and electrolytes imbalance. The aim of this study was to compare changes in the clinical and biochemical parameters in fasting and nonfasting hemodialysis patients durin...

Hollow carbon nanospheres/silicon/alumina (CNS/Si/Al₂O₃) core-shell films obtained by the deposition of Si and Al₂O₃ on hollow CNS interconnected films are used as the anode materials for lithium-ion batteries. The hollow CNS film acts as a three dimensional conductive substrate and provides void space for silicon volume expansion during electrochemical cycling. The Al2O3 thin layer is benefici...

The pH of TEMPOL electrolyte greatly affects the reversibility of its redox reaction. Reaction of TEMPOL with OH ion causes the decrease of electrolyte pH. TEMPOL in an acidic electrolyte leads to a decrease in its concentration. a r t i c l e i n f o

OBJECTIVES Longitudinal studies have linked stress at work with a higher incidence of musculoskeletal pain. We aimed to explore the extent to which musculoskeletal pain is a cause as opposed to a consequence of perceived occupational stress. METHODS As part of the international cultural and psychosocial influences on disability study, we collected information from 305 Italian nurses, at basel...

OBJECTIVES The study has aimed to identify the relations between the supplementary person-organization fit (P-O fit) and the perceived stress among managerial staff, with special regard to the mediating role of the effort-reward balance. MATERIAL AND METHODS The study sample consisted of 715 middle-level managers, aged 25-64 years old, employed in large companies. To measure the selected vari...
