An astonishingly broad application potential in biotechnology, biomimetics, and nanotechnology is revealed by studies on the structure, chemistry, biosynthesis, genetics, self-assembly, and function of supramolecular surface layers (S layers). These are monomolecular, crystalline assemblies of protein or glycoprotein subunits and represent one of the most commonly observed surface structures of...

Most highly derived olfactory systems, such as the insect antennal lobe, discriminate among a wide array of monomolecular odourants and blends of odourants. Given the relatively limited number of neurons used to code these odours, this ability implies that neural representations for odours overlap in a cross-fiber coding scheme. Here we use the generalization of a conditioned feeding response i...

A model of postphotodissociative monomolecular (geminate) recombination of heme proteins with small ligands (NO, O2 or CO) is represented. The non-exponential decay with time for the probability to find a heme in unbound state is interpreted in terms of diffusion-like migration of ligand between protein cavities. The temporal behavior for the probability is obtained from numerical simulation an...

Formation of a monomolecular layer (the Langmuir monolayer) at the air/water interface is a self-organized process. On the basis of measurements of A isotherms, mechanical and thermodynamic properties of 2D molecular systems can be evaluated. The concept is applied to the study of molecular interactions in a binary system in biological membranes: L-dimyristoyl phosphatidylcholine (DMPC) and gra...

The calixarene derivative used in this study (tetra-p-guanidinoethylcalix[4]arene) shows vitro activity against different Gram-positive and Gram-negative bacteria. interaction between bacterial cell membranes the water-soluble was investigated using model lipids spread as monomolecular films at air–water interface. Compression adsorption experiments, well Brewster angle microscopy, polarization...

Monomolecular films of 9-cis, 11-c/5, 13-cis and all-trans retinal were formed at an air-water interface. Area/molecule and surface potential were measured before, during and after illumina­ tion. The initial quantum yield of the photoisomerization o f 9-cis retinal was 0.25. Irradiation of a retinal monolayer resulted in 30 to 60 m Volt changes in surface potential. Complexation of retinals wi...

The effects of reaction conditions on the yield ethylene and propylene from pentene cracking were investigated in a fixed-bed reactor at 500–750 °C for weight hourly space velocity (WHSV) 15–83 h−1. total reached maximum (67.8 wt%) 700 57 In order to explore mechanism high temperatures, thermal/catalytic proportion model was established. It found that feed chemically adsorbed with acid sites cr...
