Polysilazane coatings have a broad need in real-life applications, which require low processing or working temperature. In this work, five commercially available polysilazanes been spin-coated on polycarbonate substrates and cured ambient environment temperature to obtain transparent, crack-free, dense films. The degree of crosslinking is found significant impact the hardness Young's modulus po...

in this assay, the evaluation of lipophilicity of four ace-inhibitors and hydrochlorothiazide (hctz) with rp-tlc on cellulose layers was described using three binary solvent systems. the selected ace inhibitors had sufficiently different structures which can indicate the method suitability for their lipophilicity evaluation as the model substances in comparison with hctz. in addition, the linea...

Soil water repellency (hydrophobicity) prevents from wetting or infiltrating soils, triggering changes in the ecosystems. This physical property is directly correlated to erodibility grade of a soil. Wildfire events may develop, enhance, destroy soil hydrophobicity, modifying and increasing loss its most reactive layer (organic matter). To assess main organic family compounds (biomarkers) surro...

The adhesion of Lactobacillus rhamnosus GG to human enterocyte-like Caco-2 cells was not inhibited by eight carbohydrates tested, namely N-acetyl-glucosamine, galactose, glucose, fructose, fucose, mannose, methyl-alpha-D-mannopyranoside and sucrose. The degree of hydrophobicity predicted the adhesion of L. rhamnosus GG to Caco-2 cells. L. rhamnosus GG, however, was able to compete with Escheric...

The influence of microwave treatment on the surface roughness, hydrophobicity, and chemical composition of galena was studied. The pure galena specimens and purified galena concentrate were used in this work. A conventional multi-modal oven (with a frequency of 2.45 GHz and a maximum power of 900 W) was used to conduct the experiments. The results obtained from the atomic-force microscopy analy...

In this assay, the evaluation of lipophilicity of four ACE-inhibitors and hydrochlorothiazide (HCTZ) with RP-TLC on cellulose layers was described using three binary solvent systems. The selected ACE inhibitors had sufficiently different structures which can indicate the method suitability for their lipophilicity evaluation as the model substances in comparison with HCTZ. In addition, the linea...

Pressure-sensitive adhesives (PSAs) are the major source of stickies in paper recycling. It is desirable that the PSA not break down into very small pieces during repulping so that it can be screened out. However, it is not clear in the literature what mechanical properties of PSAs are required to make PSAs screenable. In this study, the screenability of a range of PSAs was evaluated. The hydro...
