The anodic oxidn. of 4-chlorophenoxyacetic acid (CPA) on synthetic B-doped diamond thin film electrodes in acid media was studied, using cyclic voltammetry and bulk electrolysis. The results showed that in the potential region where the supporting electrol ...
Solid epoxy resins are produced at Vantico SA by catalyzed reactions of a low-mol. wt. liq. resin (RBL) with bisphenol A (BPA). These reactions lead to solid epoxy resins, which are used in surface coatings or adhesives. The chain lengthening step (advance ...
This article presents recent work investigating the unimolecular dissociation rates of quantum state-selected molecules. Such studies provide the most stringent test for quantitative models of unimolecular reactions and their assumptions. After briefly rev ...
The reaction of 1-bromo-3-halo-2-iodobenzene (I; X = Cl) with butyllithium gives 62% (II; X = Cl) similarly reaction of [I; X = F(III)] gave 64% II (X = F). These reactions involve the immediate intermediacy of the halolithiobiphenyl (IV) and the penultima ...
A stepwise approach to the development of artificial O6-alkylguanine-DNA alkyltransferases (AGTs) and its application to the in vitro selection of antibodies with highly reactive cysteine residues are described. As a result of low reactivity of O6-alkylate ...
We have investigated different possible mechanisms for the cis-trans isomerization in triply bonded ditungsten complexes with stoichiometry W2Cl4(NHEt)2(PMe3)2 using static d. functional calcns. as well as Car-Parrinello simulations. Our studies reveal an ...
In mobile ad-hoc networks, nodes do not rely on any routing infrastructure but relay packets for each other. Thus communication in mobile ad-hoc networks functions properly only if the participating nodes cooperate in routing and forwarding. However, it ma ...
The electrochem. oxidn. of benzoic acid (BA) was studied on boron-doped diamond electrodes on acid medium by cyclic voltammetry and bulk electrolysis. In the potential region where the supporting electrolyte is stable, reactions occur, resulting in the los ...
A method for encapsulating a core material within a capsule having a permeable or semipermeable membrane is disclosed using a complex formation reaction between oppositely charged polymers, wherein one of the polymers is an oligosaccharide such as chitosan ...
The reactivity of sulfur dioxide toward variously substituted butadienes was explored in an effort to define the factors affecting the competition between the hetero-Diels-Alder and cheletropic additions. At low temperature (< -70degrees), 1-alkyl-substitu ...
