We propose a new fully aqueous electrochemical method for the preparation of high resolution alpha sources. Thin films of polypyrrole (PPy) are prepared by anodic electropolymerization, starting from aqueous solutions of the pyrrole monomer and an anionic polyelectrolyte which is able to complex actinide and play the role of PPy doping agent: polyacrylamidoglycolic acid (PAGA). These thin films can be prepared on various electrodes: stainless steel, platinum, glassy carbon and polyethylene doped by carbon-black. Peeling tests revealed their strong adhesion on stainless steel electrode. Alpha sources were prepared by simple immersion in actinide containing solutions. This easy process results in alpha sources with outstanding energy resolution (FWHM: around 9 keV for various isotopes). [less ▲]

Summary The electrochemical reduction of uranium and neptunium ions is achieved in aprotic solvents in presence of acrylonitrile. The cathodic deposit on a usual metal consists of a grafted poly- acrylonitrile layer in which actinide oxide or actinide metal has been inserted as a consequence of the overall cathodic reaction. As polyacrylonitrile is an insulating material, the electrochemi- cal polymerization reaction is stopped when the polymer layer thickness reaches 1000 A at maximum. The material we thus produced may be used as an alpha spectroscopy source and we report here the results originating from the preparation of more than hundred samples. [less ▲]

Rennet was immobilized on porous glass beads (50-100 mesh) using diazotization [Paquot et al., DSA 38, 5851], TiCl4 [Barker et al., Process Biochemistry (1971) 5, 11], glutaraldehyde [Stanley & Olson, Journal of Food Science (1974) 39, 660] or glutaraldehyde followed by reduction of aldehyde groups by NaBH4 [Cheryan et al., DSA 38, 6728]. Residual enzyme activity was low using all 4 methods, being highest using TiCl4 (24.4%). After 13 days storage, loss of enzyme activity using diazotization and TiCl4 was resp. 82 and 58%. Activity of rennet immobilized using TiCl4 decreased with time during the passage of milk through the column, this being due to release of enzyme rather than denaturation. Ca2+ ions were responsible for the release; loss of enzyme activity during four 15-min passages of whey, casein solution (pH 7) and casein solution + EDTA was resp. 87, 57 and 4.5%. Precoating the glass beads with serum albumin resulted in significant increases in residual activity of rennet, particularly when immobilized using glutaraldehyde/NaBH4. This improvement diminished on storage. [less ▲]

Thin films of polypyrrole doped by polyanions have been deposited onto stainless steel and carbon fibers by anodic electropolymerization of pyrrole in the presence of an anionic polyelectrolyte in water. Films with a thickness smaller than 600 nm have been formed, which strongly adhere to the solid supports. The polymeric dopant has been selected for its ability to complex silver ions. Scanning electron microscopy, Rutherford backscattering analyses, and IR spectroscopy have confirmed that silver is actually immobilized in the films and provides them with an antibacterial activity against the Gram-negative bacteria Escherichia coli and Gram-positive bacteria Staphylococcus aureus.

Lipases are able to catalyse the hydrolysis of glyceridic esters in aqueous media and the synthesis of esters in non-aqueous media. They are thus able to catalyse numerous reactions of industrial interest. Whether it is by inclusion, by adsorption or by covalent link, the immobilisation of lipases aims at conferring them a good stability that enables a reuse of the enzymes after a reaction and the development of continuous processes. The reactions of triglycerides hydrolysis constitute main applications for immobilised lipases, however their use in different types of esterification reactions has also arose: there exist processes involving reactions of transesterification, of interesterification or of esters synthesis. The production of structured lipids by interesterification is one example. Although the reaction conditions dissent from those of hydrolysis, the same lipases have been used in both cases. A lipase specifically adapted for esterification though would be a highly capable tool: a series of strategies is in progress in order to reach this goal. [less ▲]
