Standing benifit

Pseudocapacitance holds great promise for energy density improvement of supercapacitors, but electrode materials show practical capacity far below theoretical values due to limited ion diffusion accessibility and/or low electron transferability. Herein, inducing two kinds of straight ion-movement channels and fast charge storage/delivery for enhanced reaction kinetics is proposed. Very thick electrodes consisting of vertically aligned and ordered arrays of NiCo2S4 nanoflake covered slender nickel columns (NCs) are achieved via a scalable route...

In the year 2000, 5357 employees were interviewed on physical work environment and various co-variates. They were followed for 18 months in order to identify people receiving sickness benifits for eight weeks or more. 348 persons (7%) developed long-term sickness. 56% were women. Risk of long-term sickness absence was increased by extreme bending or twisting of the neck or back, working mainly standing or squatting, lifting or carrying loads, and pushing or pulling loads. Three significant interactions of physical and psychosocial work environment risk factors were found among women...
