Compared to traditional lead-acid batteries with an energy density ofaround 50-100 Watt-hour per kg (Wh/kg), lithium-ion batteries have atypical energy density of about 260-270 Wh/kg. This makes lithium-ion batteries the preferred choice for any compact appliances that need a long battery li...
As described in REACH guidance R.11, the aim of these simulation tests is to provide a definitive degradation half-life that can be compared directly to the persistence criteria of Annex XIII of REACH and thus permit a con- clusion of the assessment to be reached. It is envisaged that ...
Liq. to be automatically reduced by evapn. to a specific vol., measured by wt., is held in an open-topped container (8) fitting into the cavity of a surrounding heater (1), and resting on an internal or external load cell (2). Evapn. is caused by a stream of inert gas ...
worldwide are implementing policies to reduce greenhouse gas emissions leading to a focus on lightweighting as a key strategy.As lightweight vehicles consume less fuel and emit fewer pollutants compared to heavier counterparts making them increasingly attractive in markets with stringent environmental ...
Lightweight structures comprise of actual pieces or segments that give the crucial ability to function while weighing less than other possibilities as well
Intestinal epithelial CNDP2+ cells, not macrophages, are the principal in vivo source of basal and metformin-inducible Lac-Phe. Genetic ablation of Lac-Phe biosynthesis in male mice renders animals resistant to the effects of metformin on food intake and body weight. Lastly, mediation analyses ...
35. Gas permeation studies have shown that water permeation in PEI, which occurs almost instantaneously, is governed by osmotic pressure gradients33,36,37. Indeed, studies of free-standing polymeric membranes show that mechanical stresses generated ahead of the diffusion front modify the polymer chain...
The molecular weight changes in abiotically and biotically degraded LDPE and LDPE modified with starch and/or prooxidant were compared with the formation of degradation products. The samples were thermooxidized for 6 days at 100C to initiate degradation and then either inoculated with Arthobacter pa...
ultra-lightweight frame for a flatbed trailer, optimized the thicknesses of the member plates and the boundary shapes with the Taguchi method through computer aided engineering (CAE) software, improved frame bending and torsional stiffness, and reduced its mass by 24.5% compared to the original ...
