Safety issues concerning the use of large lithium-ion (Li-ion) batteries in electrified vehicles are discussed based on the abuse test results of Li-ion cells together with safety devices for cells. The presented abuse tests are: overcharge, short circuit, propane fire test and external heating test (oven). It was found that in a fire, cells with higher state of charge (SOC) gave a higher heat ...

The excited-state hydride release from 10-methyl-9-phenyl-9,10-dihydroacridine (PhAcrH) was investigated using steady-state and time-resolved UV/vis absorption spectroscopy. Upon excitation, PhAcrH is oxidized to the corresponding iminium ion (PhAcr(+)), while the solvent (acetonitrile/water mixture) is reduced (52% of PhAcr(+) and 2.5% of hydrogen is formed). The hydride release occurs from th...

UNLABELLED Somatostatin increases absorption of electrolytes and inhibits diarrhea in patients with endocrine tumors and short bowel syndrome. In an attempt to develop a gut-specific somatostatin analog, each amino acid in the somatostatin molecule was replaced with L-alanine, deleted, or substituted with its D-isomer. The potency of each analog to stimulate ion transport in the rabbit ileum wa...

Ion exchange resins (IER) are cross-linked, water insoluble polymers carrying ionizable functional groups on their repeating positions. They are considered as safe materials due to their insoluble and nonabsorbable nature. This advantage made IER subject of several research in different areas of pharmaceutical technology such as oral sustained release, taste masking, rapid dissolution, stabilit...

This study aims to successfully demonstrate natural clinoptilolite based ammonia capture from real swine wastewater and simulated Anaerobic Membrane Bioreactor (AnMBR) treated permeate through extensive experimental analysis. The surface structure as well elemental chemical composition of both untreated particles were characterized using Scanning electron microscopy (SEM) - Energy dispersive X-...

A study has been carried out to determine the effect of coating two commercial glass-ionomer cements in either petroleum jelly or wax. After coating, specimens were stored in water for 24 or 168 hours, then the coating removed and the surface examined. Coating in wax was found to increase the surface hardness significantly compared with the uncoated control, whereas coating the specimens in pet...

In the brain, hundreds of intracellular processes are known to depend on calcium influx; hence any substantial fluctuation in external calcium ([Ca2+]o) is likely to engender important functional effects. Employing the known scales and parameters of mammalian neural tissue, we introduce and justify a computational approach to the hypothesis that large changes in local [Ca2+]o will be part of no...

P-type ATPases are a large family of membrane proteins that perform active ion transport across biological membranes. In these proteins, the energy-providing ATP hydrolysis is coupled to ion transport of one or two ion species across the respective membrane. The pump function of the investigated pumps is described by a so-called Post-Albers cycle. Main features of the pumping process are (1) a ...
