Collagen is constituted of three polypeptides forming a triple helix maintained by numerous weak chemical interactions, such as hydrogen bonds. In connective tissue it further packs into very long cylinders of few nanometers of diameter, called fibrils. On ...
The stabilizing role of permanent Ir modifier deposited on W-treated (WTP) and Zr-treated (ZrTP) platforms of transversely heated graphite atomizer (THGA) was studied in detail by electrothermal at. absorption spectrometry (ETAAS) and different surface tec ...
A review and discussion with 59 refs. Schrodinger stated in his landmark book, What is Life, that life feeds on neg. entropy. In this contribution, the validity of this statement is discussed through a careful thermodn. anal. of microbial growth processes. ...
An understanding of the behaviour of saturated/unsaturated soils is important for the design and analysis of geostructures. In this paper a continuum approach based on a structured thermodynamic theory of mixtures developed by Svendsen & Hutter (1995), in ...
The thermodn. and kinetics of ligand binding to the purified serotonin 5HT3 receptor and the local environment of the bound ligand were studied by fluorescence spectroscopy using a novel fluorescein-labeled ligand GR-flu [1,2,3,9-tetrahydro-3-[(5-methyl-1H ...
We have investigated the kinetics of germinate carbon monoxide binding to the monomeric component III of Chironomus thummi-thummi erythrocruorin, a protein that undergoes pH-induced conformational changes linked to a pronounced Bohr effect. Measurements we ...
An efficient synthesis of cycloisodityrosine was developed based on an intramol. nucleophilic arom. substitution reaction for the selective ring formation of a key biaryl ether intermediate. Cycloetherification of dipeptide I gave exclusively the (meta,par ...
A review, with over 209 refs., is given on the prepn. and structures of all known salts of the known homopolyat. cations of the chalcogens and halogens. The structures of these cations, many of which are nonclassical and cluster-like, arise from pos. charg ...
Poly-quasicrystalline samples of an icosahedral Al-Cu-Fe alloy have been deformed in compression tests under constant-strain-rate conditions at temperatures ranging from room temperature up to 1020 K (m approximate to 1150 K, where T-m is the melting tempe ...
Simplified vibrational densities of states for five different carbonates are constructed using measured IR and Raman spectra. From the spectroscopic models we calculate thermodynamic and thermoelastic properties of magnesite, calcite, aragonite, dolomite, ...
