The Diels-Alder adduct of furan and 1-cyanovinyl (1'R)-camphanate was converted into methyl[(tert-butyl)dimethylsilyl 5-deoxy-2,3-O-isopropylidene-beta-L-ribo-hexofuranosid]uronate ((+)-4). Reduction with diisobutylaluminium hydride gave the corresponding ...
We performed high-resolution angle resolved photoelectron spectroscopy studies of quasi-one-dimensional organic materials. For TTF-TCNQ, we observe dispersive spectral features corresponding to the donor and acceptor band. For the Bechgaard salts (TMTSF)(2 ...
We performed a photoemission investigation of the electronic structure of PrNiO3 and NdNiO3 through the first order (paramagnetic) metal to (antiferromagnetic) insulator transition. Surprisingly, the data reveal a temperature-dependent loss of spectral wei ...
The gibbsian model for surfaces is reformulated in order to account for stress and strain within quasi-ideal crystals and on their surface. Tensor calculus, extensively used, leads to an invariant formalism. The symbols appearing therein are given a physic ...
Regional budgets of pollutants in the atmospheric boundary layer (ABL) provide valuable information on transport and chemical processes, especially over complex terrain where local assessments are not representative. Horizontal transport, vertical transpor ...
A review with 21 refs. on the strategy of wastewater treatment in org. chem. industry. Biodegradability tests, toxicity tests, aerobic and anaerobic treatment processes, and electrochem. oxidn. of org. substances are discussed with an example of a pilot pl ...
The most important advances in the field of biomaterials over the past few years have been in bioactive biomaterials. Materials have been developed to incorporate bioactivity through biological recognition, including incorporation of adhesion factors, poly ...
We present a study of the textural signature of terrestrial weathering and related biological activity in the Tatahouine meteorite. Scanning and transmission electron microscopy images obtained on the weathered samples of the Tatahouine meteorite and surro ...
