Journal of Applied Polymer Science, EarlyView.ABSTRACT The aim of the research was to find a fast and reliable measurement method for the prediction of functional properties such as compression set (CS) of rubber profiles. Research shows that the best method for testing network density and crosslinks structure for a finished product, such as complex car seals, is equilibrium swelling. Measurements

Ecology and Evolution of Soil Nematode Chemotaxis [PDF]
, 2018 Plants influence the behavior of and modify community composition of soil-dwelling organisms through the exudation of organic molecules. Given the chemical complexity of the soil matrix, soil-dwelling organisms have evolved the ability to detect and ...

Biotechnology and Applied Biochemistry, EarlyView.ABSTRACT Macrocyclic calix[n]arenes have many applications, with diverse structures that can easily be functionalized either on upper or lower rims, mostly to impart solubility and improve biological activities. In this study, triazole‐based p‐tert‐butylcalix[4]arene conjugates (AT10a and AT10b) and their p‐tert‐butylphenol analogs (AT10b and AT11b ...

Chemistry – A European Journal, EarlyView.A polydentate ligand with multiple coordination patterns (bidentate N*N‐mode for Pt(II) and Re(I) centers, tridentate C^N*N‐motive for Pt(II)‐based complexes) is herein presented. The attained coordination‐chemical versatility in combination with different co‐ligands was employed to achieve sophisticated structural features and tunable photophysical ...
