Medical-grade poly(vinyl chloride) (PVC) was chemically modified to study how the incorporation of monovalent silver influences Pseudomonas aeruginosa adhesion and colonization. The modification investigated consisted of a radio frequency-oxygen (RF-O-2) g ...
Selective dissolution of titanium through a laser patterned oxide film has been achieved in a 3M sulfuric acid-methanol electrolyte. The 250 nm thick oxide film was formed anodically on a flat titanium surface in 0.5 M sulfuric acid. The patterning of the ...
The hetero-Diels-Alder addition of sulfur dioxide to (E)- and (Z)-4-(fluoromethylidene)-3-methylene-2,3-dihydro-naphthalene follows the endo Alder rule. The first example of a crystalline sultine has been obtained. In agreement with high level quantum calc ...
This paper presents the results of an experimental program designed to assess the durability of sisal and coconut fibres exposed to alkaline solutions of calcium and sodium hydroxide. In addition, the durability and microstructure of the cement mortar comp ...
Under appropriate conditions sulfur dioxide reacts with 1,3-dienes in the hetero-Diels-Alder fashion. In the case of 1-alkoxy-1,3-dienes the 6-alkoxy-3,6-dihydro-1,2-oxatiin-2-oxides (sultines) so-obtained can be ionized in the presence of Lewis or protic ...
N-(Fluoro-3-methoxyacryloyl)anilines [2-fluoro-3-methoxy-2-propenanilides] can be prepd. by condensation between lithium anilides and Me 2-fluoro-3-methoxy-2-propenoate. For example, the reaction of (E)- and (Z)-2-fluoro-3-methoxy-2-propenoic acid Me ester ...
The electrochem. hypochlorination of allyl chloride [107-05-1] was studied. The reaction is best effected using 1-1.5N HCl as the electrolyte, introducing allyl chloride as an emulsion and working at low c.d. (
An encapsulation device, designed on the basis of the laminar jet break-up technique, is characterized for cell immobilization with different types of alginate. The principle of operation of the completely sterilizable encapsulator, together with technique ...
At low temperature, 1-alkoxy-1,3-dienes add to sulfur dioxide activated by a Lewis or protic acid generating zwitterionic intermediates that can be quenched by enoxysilanes. The resulting beta,gamma-unsaturated silyl sulfinates can be desilylated by 1:1 Pd ...
The electrochem. prepn. of ceric sulfate [13590-82-4] was studied in concd. H2SO4 (10 mol/dm3). The current efficiency of the reaction increases considerably if a mixed catalyst (Ag2SO4 + MnSO4) is used. [on SciFinder (R)] ...
