Study of corrosion inhibition properties of Schinus molle essential oil on carbon steel in HCl

The inhibitory action of Schinus molle L. essential oil was investigated for the corrosion of carbon steel in 1 M hydrochloric acid solution using weight loss, polarization curves, and electrochemical impedance spectroscopy. The inhibition efficiency has increased with the increase of the inhibitor concentration, reaching a value of up to 70% at 2 g/L.

Lipid Emulsions Differentially Affect LPS-Induced Acute Monocytes Inflammation: In Vitro Effects on Membrane Remodeling and Cell Viability

The aim of this study was to assess how lipid emulsions for parenteral nutrition affect lipopolysaccharide (LPS)‐induced acute monocyte inflammation in vitro. An 18 h long LPS induced human monocyte leukemia cell stimulation was performed and the cell‐growth medium was supplemented with three different industrial lipid emulsions: Intralipid^®, containing long‐chain triglycerides (LCT—soybean oil); Medialipid^®, containing LCT (soybean oil) and medium‐chain triglycerides (MCT—coconut oil); and SMOFlipid^®, containing LCT, MCT, omega‐9 and ‐3 (soybean, coconut, olive and fish oils). Cell viability and apoptosis were assessed by Trypan blue exclusion and flow cytometry respectively. Monocyte composition and membrane remodeling were studied using gas chromatography and NR12S staining. Microparticles released in supernatant were measured by prothrombinase assay. After LPS challenge, both cellular necrosis and apoptosis were increased (threefold and twofold respectively) and microparticle release was enhanced (sevenfold) after supplementation with Medialipid^® compared to Intralipid^®, SMOFlipid^® and monocytes in the standard medium. The monocytes differentially incorporated fatty acids after lipid emulsion challenge. Finally, lipid‐treated cells displayed microparticles characterized by disrupted membrane lipid order, reflecting lipid remodeling of the parental cell plasma membrane. Our data suggest that lipid emulsions differentially alter cell viability, monocyte composition and thereby microparticle release. While MCT have deleterious effects, we have shown that parenteral nutrition emulsion containing LCT or LCT and MCT associated to n‐3 and n‐9 fatty acids have no effect on endotoxin‐induced cell death and inflammation.     

Bisphenol S and bisphenol A cyanate ester/barium metaborate composites

The aim of this study was to improve thermal stability and surface properties of bisphenol A dicyanate ester (BADCy) by adding bisphenol S dicyanate ester (BSDCy) and Ba(BO₂)₂. Bisphenol S and bisphenol A cyanate ester/barium metaborate composites having various ratios of BADCy, BSDCy, and Ba(BO₂)₂ were prepared. Thermal stability of the samples was evaluated by thermogravimetric analysis and differential scanning calorimetry. Hydrophobicity of the samples was determined by the contact angle measurements. The samples were characterized with the following analysis; gel content, water absorption capacity. Moreover, the surface morphology of the samples was investigated by a scanning electron microscopy. The obtained results prove that the cyanate ester containing sulfonyl/Ba(BO₂)₂ composites have good thermal and surface properties and they can be used in many applications such as electronic devices, materials engineering, and other emergent.

Correlation between high pressure effect and alloying in GaAs and Ga1-xAlx As

The empirical pseudopotential method coupled with the virtual crystal approximation has been used to compute the electronic band gaps and pseudocharge densities for the compound semiconductor GaAs and the alloy Ga_1−xAl_xAs. The variation of the compositional fraction of AlAs in GaAs has been correlated to the high pressure effect on GaAs.
