Coil‐Type Asymmetric Supercapacitor Electrical Cables

Cable‐shaped supercapacitors (SCs) have recently aroused significant attention due to their attractive properties such as small size, lightweight, and bendability. Current cable‐shaped SCs have symmetric device configuration. However, if an asymmetric design is used in cable‐shaped supercapacitors, they would become more attractive due to broader cell operation voltages, which results in higher energy densities. Here, a novel coil‐type asymmetric supercapacitor electrical cable (CASEC) is reported with enhanced cell operation voltage and extraordinary mechanical‐electrochemical stability. The CASECs show excellent charge–discharge profiles, extraordinary rate capability (95.4%), high energy density (0.85 mWh cm⁻³), remarkable flexibility and bendability, and superior bending cycle stability (≈93.0% after 4000 cycles at different bending states). In addition, the CASECs not only exhibit the capability to store energy but also to transmit electricity simultaneously and independently. The integrated electrical conduction and storage capability of CASECS offer many potential applications in solar energy storage and electronic gadgets.

The Pathophysiological Role of CoA

The importance of coenzyme A (CoA) as a carrier of acyl residues in cell metabolism is well understood. Coenzyme A participates in more than 100 different catabolic and anabolic reactions, including those involved in the metabolism of lipids, carbohydrates, proteins, ethanol, bile acids, and xenobiotics. However, much less is known about the importance of the concentration of this cofactor in various cell compartments and the role of altered CoA concentration in various pathologies. Despite continuous research on these issues, the molecular mechanisms in the regulation of the intracellular level of CoA under pathological conditions are still not well understood. This review summarizes the current knowledge of (a) CoA subcellular concentrations; (b) the roles of CoA synthesis and degradation processes; and (c) protein modification by reversible CoA binding to proteins (CoAlation). Particular attention is paid to (a) the roles of changes in the level of CoA under pathological conditions, such as in neurodegenerative diseases, cancer, myopathies, and infectious diseases; and (b) the beneficial effect of CoA and pantethine (which like CoA is finally converted to Pan and cysteamine), used at pharmacological doses for the treatment of hyperlipidemia.     

ENTOREL Database for electronic components under gamma radiation-adescription

The ENTOREL Database for radiation stressed electronic components and systems has been established to collate data on high doses (aiming at Mega Grays) which meet the requirements of advanced teleoperators working in hazardous or disordered nuclear environments within the frame of a European telerobotics programme for the nuclear industry. The ENTOREL Database holds data from 614 tests on total dose effects     

Immigrants and health: unemployment and health-risks of labour migrants in the Federal Republic of Germany, 1984-1992

This article presents a longitudinal study of employment, unemployment and health of migrant workers in Germany. The analyses were conducted with longitudinal samples of the waves 1-6 (1984-1989) and the waves 6-9 (1989-1992) of the German Socio-Economic Panel (GSOEP). German and migrant workers did not respect to their health satisfaction but unemployed foreign workers were quite less satisfied with their health than unemployed Germans. This corresponded with a high percentage of foreign unemployed (30-50%) who felt chronically ill. A further examination of two (dichotomously formulated) principal investigation hypotheses could not show that the data support the explanation that the poorer health of unemployed migrants was caused by the unemployment situation. The results are interpreted in the way that the unemployed migrants' poorer health can be explained with (health) selection processes in the labour market.     

The preparation and properties of coprecipitated Cu–Zr–Y and Cu–Zr–La catalysts used for the steam reforming of methanol

Several samples of exhaust diesel soot are investigated by inverse gas chromatography and linear solvation energy relationship (LSER) modelling according to their soluble organic fraction content and their time of exposure in oxidative conditions. The results demonstrate the evolution of the adsorptive properties of the studied materials towards volatile compounds during the oxidation under NO₂.
