The residue of no-clean flux (NCF) on the printed circuit board assembly has been one major reasons for corrosion reliability failure electronic devices. source aggressive contamination is carboxylic acid activator as main cleaning agent soldering surfaces. Selecting suitable always concerns due to its conflicting properties, example, suberic a lower boiling point that will help in minimizing r...

Isodon rugosus Wall. ex Benth. is extensively used as traditional medicine for the management of various types of pain including tooth ache, gastric pain, abdominal pain, ear ache, and generalized body pain. The current study is designed to scientifically verify the purported uses of I. rugosus as analgesic agent and to figure out its possible mechanism of action. Bioactive compounds responsibl...

A main-chain, polydomain, smectic liquid crystalline elastomer (LCE) was prepared by reacting the LC epoxy monomer, diglycidyl ether of 4,4′-dihydroxy-R-methylstilbene, with the aliphatic diacid, sebacic acid. When deformed in uniaxial tension, a “polydomain-to-monodomain” transition took place leading to bulk, macroscopic orientation. With this process was associated a plateau in the nominal s...

This work examines the biocompatibility of poly(octanediol citrate)/sebacate (p(OCS)) biodegradable polyester elastomers. The growth of human MG63 osteoblast-like cells was studied on p(OCS) films. Three types of p(OCS) films were synthesised simply by varying the concentrations of 1,8-octanediol (OD), citric acid (CA), and sebacic acid (SA) monomers at initial molar ratios of 1:1:0, 1:0.75:0.2...

Biotechnologically accessible 1,4-butanediol and vegetal oil-based diethyl sebacate were copolymerized with bicyclic acetalized D-glucose derivatives (Glux) by polycondensation both in the melt at high temperature and in solution at mild temperature mediated by polymer-supported Candida antarctica lipase B (CALB). Two series of random copolyesters (PB(x)Glux(y)Seb and PBSeb(x)Glux(y)) were prep...

We have previously reported that the use of the polymer bis(p-carboxyphenoxy)propane-sebacic acid (20:80) for intratumoral delivery of cis-platinum in a mouse tumor model (RIF-1) potentiated the effects of acute and fractionated radiation. This mode of drug delivery seems particularly applicable to the administration of radiosensitizing drugs because an optimum concentration of radiosensitizer ...

Trans-10-hydroxy-2-decenoic acid (10-H2DA), 10-hydroxydecanoic acid (10-HDAA), and sebacic acid (SEA) are the three major fatty acids in royal jelly (RJ). Previous studies have revealed several pharmacological activities of 10-H2DA and 10-HDAA, although the anti-inflammatory effects and underlying mechanisms by which SEA acts are poorly understood. In the present study, we evaluated and compare...
