A SnO2-doped dicalcium phosphate coating was prepared on AZ31 alloy by means of hydrothermal deposition. The results showed that the coating possessed a globular morphology with a long lamellar crystalline structure and a thickness of approximately 40 μm. The surface of the coating became smoot...

The effect of long-chain fatty acid adsorption on the wetting states of calcite and mica powders is investigated. The selected long-chain fatty acids are saturated or unsaturated aliphatic acids (stearic acid and oleic acid, respectively) and naphthenic acids with saturated or unsaturated aromat...

Herein, an amphiphilic hexadecyl gellan copolymer was synthesized and characterized by FTIR, elemental analysis and its degree of substitution. The copolymer self-assembled in water and formed spherical nanostructures. Simvastatin was loaded into micelles by solvent evaporation method. The criti...

A visible-light Z-scheme g-C3N4/Fe0/TiO2 anodic catalyst was tested with cathodic WO3 in photocatalytic Fuel Cell (PFC) that efficiently degrades berberine chloride and simultaneously generate electricity at pH 2,5,7 and 13. The Stainless-steel mesh electrodes loaded with prepared catalyst were ...

A series of Cu2O/Cu/AgBr/Ag photocatalysts were synthesized by a redox procedure followed by photo-assisted deposition. X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS) were utilized to characterize the...

EN 14103:2003 and EN 14103:2011 were developed in order to determine fatty acid methyl ester (FAME) content of biodiesel. The internal standards (IS) of biodiesel include methyl heptadecanoate (MHD) and methyl nonadecanoate (MND), respectively. However, since these ISs are also present in bovine...

A novel polyvinylpyrrolidone [email protected]2O4/BiOBr heterojunction photocatalyst was successfully prepared by solvothermal method using ethylene glycol as solvent and characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, ultraviolet–visible diff...

A three-component plasmonic Z-scheme g-C3N4/Ag/LaFeO3 photocatalyst was prepared via facile photo-reduction deposition and hydrothermal process. The photocatalytic activity of g-C3N4/Ag/LaFeO3 composite was examined by conducting degradation experiments of RhB and phenol under visible light. The...

High efficiency, high stability and easy recovery are three key factors for practical photocatalysts. Z-scheme heterostructure is one of the most promising photocatalytic systems to meet all above requirements. However, efficient Z-scheme photocatalysts which could absorb visible light are still...

2D/2D materials have attracted extensive attention in the field of photocatalysis due to their large contact surfaces and short charge transfer distances. However, 2D/2D heterojunction materials, especially those that connect different materials together using strong chemical bonds, are still ch...

The development of visible-light-driven photocatalysts with high photocatalytic performance is a desired research direction of scholars for energy crisis mitigation and environment restoration. In this study, a series of highly active mediator-free direct dual-Z-scheme Bi2S3/BiVO4/MgIn2S4 hybrid...

Platelet thromboxane synthesis in response to supplemental linoleate in the diet has been very inconsistent. The objective of this study was to investigate potential confounding factors known to affect platelet thromboxane synthesis. Citrated whole blood was recalcified with varying Ca2+ concent...

In healthy pancreatic islets, glucose-stimulated changes in intracellular calcium ([Ca2+]i) provide a reasonable reflection of the patterns and relative amounts of insulin secretion. We report that [Ca2+]i in islets under stress, however, dissociates with insulin release in different ways for di...

The ability of hematin (4·9 μm) to catalyze oxidation of a linoleate emulsion in dimethyl arsenic acid buffer, pH 7·4, was tested as a function of calcium (20 mm), β-casein (250 μm) and temperature (7°–25°C). A polarographic oxygen sensor was used to monitor reaction rates. In all sample...

Epithelial Ovarian cancer (EOC) is the deadliest gynecologic malignancy and represents the fifth leading cause of all cancer-related deaths in women. The majority of patients are diagnosed at an advanced stage of the disease that has spread beyond the ovaries to the peritoneum or to distant orga...

The separation between calcium minerals such as apatite and calcite by flotation relies on the use of long chain fatty acid collectors. Oleic acid, and its salt, is the main fatty acid collector and many studies have reported on the mechanisms of its interaction with calcium at the mineral surfa...

Warburg hypothesized that the energy consumption of cancer cells is different than the normal cells. When compared to normal conditions, cancer cells do not undergo tricarboxylic acid (TCA) cycle therefore resulting in more lactate in the cells. Glycolysis pathway is a way of cancer cells to pro...

Ursolic acid derivatives containing oxadiazole, triazolone, and piperazine moieties were synthesized in an attempt to develop potent anti-inflammatory agents. Structures of the synthesized compounds were elucidated by 1H NMR, 13C NMR, and HRMS. Most of the synthesized compounds showed pronounced...

We recently presented that compounds 4a–b moderately inhibited leukotriene (LT) formation in human neutrophils. For structural derivatization of 4a–b, novel thirty-six title compounds were synthesized and led to more potent inhibition of LT biosynthesis in activated human neutrophils exemplifi...
