Materials science is a highly interdisciplinary field. It is devoted to the understanding of the relationship between (a) fundamental physical and chemical properties governing processes at the atomistic scale with (b) typically macroscopic properties required of materials in engineering applications. For many materials, this relationship is not only determined by chemical composition, but stro...

Binuclear complexes of Ni(i) have been prepared from a 4-terphenyldithiophenol ligand. Steric effects were found to determine the formation of coordination isomeric structures that differ in the nature of metal-to-ligand bonding. Coordination of spatially demanding phosphine ligands PR3, R = C6H6, C6H11, at nickel sites results in a butterfly shaped thiolate-bridged Ni2(μ-S)2 motif. For smaller...

Proteins play diverse and vital roles in biology, which are dominated by their three-dimensional structures. The three-dimensional structure of a protein determines its functions and chemical properties. Protein secondary structures, including α-helices and β-sheets, are key components of the protein architecture. Molecular interactions, in particular hydrogen bonds, play significant roles in t...

1. Methods for the concentration of Type I pneumococcus antibody have been outlined. 2. The physical and chemical properties of the purified antibody have been described. 3. The chemical basis of serological specificity has been discussed.

Leptolstatin, a product from Streptomyces sp. SAM1595, is a gap phase-specific inhibitor of the mammalian cell cycle. Physico-chemical properties and spectrometric analyses showed that the structure of leptolstatin is (2Z,6E,8Z,12E,14E,22E)-19,24-dihydro xy-8,10,14,16,18,20,22-heptamethyl-17-oxo-2 , 6,8,12,14,22-tetracosahexaen-5-olide.

A novel solvent-free solid-state synthesis was used to prepare a non-crystalline polysilsesquioxane sample, with a peculiar viscous form. The material was synthesized through direct self-condensation of a partially condensed polyhedral oligomeric silsesquioxane (POSS) and its physico-chemical properties, in terms of composition/structure, thermal stability and hydrophobicity, were investigated.

The present study explored the possibility of generating a novel sensory evaluation instrument for describing comprehensive food palatability via its subdomains (rewarding, cultural, and informational) while keeping physiological factors constant. Seventy-five Japanese participants were asked to taste cheese samples and to respond to a questionnaire that was developed to dissect the distinct su...

Understanding the removal mechanisms and kinetics of trace tetracycline by activated sludge is critical to both evaluation of tetracycline elimination in sewage treatment plants and risk assessment/management of tetracycline released to soil environment due to the application of biosolids as fertilizer. Adsorption is found to be the primary removal mechanism while biodegradation, volatilization...

The arrangement of molecules in molecular networks determines their physical and chemical properties. Addressing this fundamental issue requires proper structural characterization tools. Due to an overlap, interdigitation, tilting or stacking of molecules revealing the structure of the networks is challenging. Tebi et al (2015 Nanotechnology 27 025704) developed a clever approach that enables a...

Biological tests are necessary for studying the toxicity and biochemical effects of pesticides to individual species in the animal and plant kingdoms as well as for indirect determination of biologically important physical and chemical properties of pesticides. Some of the more important requisites for meaningful application of biological tests are careful method standardization; use of sensiti...
