nano aluminium oxide

Studies on titanium porcelain interface have shown the presence of alumina mainly due to the sanding process. In this study, a study by the sand blasting effect on the microstructure and the surface roughness was cast pure titanium is carried out using three different sizes of particles of alumina powder. The analysis showed that the alumina particles are embedded in the surface layer of titanium in all cases. The use of a high alumina particle size seems to be advantageous in reducing the weight of alumina on the titanium surface and simultaneously increasing the surface roughness, thereby promoting the mechanical lock with the remaining porcelain.

What is Buckypaper

carbon nanotube paper, sometimes referred to as buckypaper, is a random arrangement of carbon nanotubes is meshed in a single robust design, which can be handled with relative ease. Multi-walled carbon nanotubes were used to make paper nanotube, and were then modified by a platinum electroless plating method using a plating, based on the substrate improvement. This includes the use of a sacrificial metal substrate of the solution on the paper nanotube via a galvanic electro-resolution displacement reaction, while the platinum metal deposits is subjected. The samples were performed using SEM / EDS, and characterized by Hall effect measurements. Analysis by SEM / EDS clearly shows the platinum deposits (Pt) distributed on the surface of nanotube paper, and qualitative elemental analysis resulted in the co-deposition of other elements of the metal substrates used. If the stainless steel as sacrificial metal of a high degree of Pt was used to contamination by various other metals was observed. So were used in pure metals victims bimetallic Pt clusters on. The co-deposition of a bimetallic system carbon nanotube is a function of the type of metal and the exposure time. Hall effect measurements revealed some interesting variations in the density of carrier sheet and the dominant carrier changed P-type N when Pt was deposited on the paper nanotube. Perspectives on the use of the nanotube paper as a substitute for conventional carbon cloth in water electrolysis systems are also discussed.

Bromoacetone

Bromoacetone is a colorless liquid with a pungent odor. He is described as a skin, eye, and respiratory irritation. Was first used Bromaceton as a chemical weapon in World War I, and can be used at present in organic synthesis, although the production data were not found. Bromoacetone was prepared by acetone treatment bromine and sodium chlorate. It occurs naturally in the essential oil of a species of algae that grow around the Hawaiian islands in the sea

What is Dihydromyricetin

disorders of alcohol consumption (AUD) is the most common form of drug abuse. The development of tolerance to repeated AUD contains lead alcohol, alcohol withdrawal syndrome (AWS), physical and psychological dependence, to control the loss of excessive alcohol consumption capacity. Currently there is no effective therapeutic agents for AUD without significant side effects. Dihydromyricetin (EHD, 1 mg / kg, ip injection), a flavonoid component of herbal medicines, counteracts acute alcohol (EtOH) noise, and withdrawal symptoms in rats, including tolerance, increased anxiety and seizure susceptibility; DHM significantly reduces the consumption of EtOH rats intermittent voluntary EtOH intake paradigm. GABA (speed) are important goals of acute and chronic EtOH actions on the brain. At the cellular level DHM (1 uM) antagonizes induced potentiation EtOH-acute BARs GABA and EtOH exposure / induced weaning GABAAR plasticity, including changes in the reactivity of the extracellular GABAARs and postsynaptic acute EtOH, and especially, increases in -unity GABAAR α4 expression in the hippocampus and neurons in culture. anti-alcohol effects DHM behavior and neurons of the central nervous system have been stymied by flumazenil (10 mg / kg in vivo, in vitro 10 uM), the benzodiazepine (BZ) antagonist. DHM competitive inhibited the site BZ [3H] flunitrazepam binding (IC50, 4.36 uM), suggesting a DHM interaction with EtOH comprises the BZ sites GABAARs. In summary, we found an anti-alcohol effect DHM animal models and determines an important molecular target and cellular mechanism of EHD counteract alcohol intoxication and dependence. We have shown the pharmacological properties of DHM are in line with expectations of a successful medical treatment AUD to reason; So DHM is a therapeutic candidate.

Human Albumin

containing a recombinant fusion protein of the long-acting human serum albumin (HSA) and human granulocyte derived colony stimulating factor (G-CSF), units derived Granulopoese having potential activity. G-CSF, a naturally occurring cytokine that stimulates the production of granulocytes and stem cells in the bone marrow and their release into the blood; it also stimulates differentiation, function and survival of neutrophil precursors and mature neutrophils. Albumin fusion, increased serum half-life and bioavailability of the G-CSF part promote this fusion protein.
