Orthorhombic TaAs: A New Topological Phase of the Archetypical Weyl Semimetal.

We report on a new, topologically nontrivial phase of TaAs identified in thin TaAs layers grown by molecular beam epitaxy. Structural investigations clearly show a new atom arrangement, confirmed by the presence of 104 reflections in the X-ray diffraction pattern, forbidden for the well-known tetragonal phase. Density functional theory confirms the presence of a new orthorhombic phase and reveals that its formation energy is slightly higher (by ∼0.

Impact of milk fat globule replacement with emulsified canola oil droplets on the composition, structure, texture, sensory properties, and lipid oxidation of fresh soft rennet cheese.

The objective of the study was to improve the nutritional quality of fresh soft rennet cheese by replacing milk fat with canola oil. The structure matrices of soft rennet cheese with 50% and 100% milk fat replacement by canola oil were designed, resulting in an analog 50% and 100%, respectively. Before the formulation, the canola oil was encapsulated by whey protein as a lipid carrier.

Shape-Selective Separation of Model Analytes in Normal-Phase Liquid Chromatography: A Combined Simulation-Experimental Study.

In this study, we demonstrate that liquid chromatographic separation can be effectively achieved based on shape differences, even for analytes of very similar chemical characters. Using a combined experimental-theoretical approach, we investigated the retention behavior of spherical buckminsterfullerene C60 and disk-shaped coronene at a hydroxylated silica stationary phase, with a mobile phase composed of toluene and -hexane at varying compositions. High-performance liquid chromatography (HPLC) measurements revealed that increasing the -hexane content enhances the separability of the two analytes, primarily due to coronene's stronger retention.

Effect of starter culture and lipase type in probiotic yogurt and sour milk with the addition of hydrolyzed walnut oil on free fatty acid, fatty acid, and conjugated linoleic acid content during fermentation and storage.

The aim of this work was to determine how the addition of hydrolyzed walnut oil, types of lipases (from Candida rugosa and porcine pancreas), and storage time affect the composition, acidity, microbiota, free fatty acid, and fatty acid content of sour milk and yogurt plus the monocultures of Lactobacillus acidophilus LA-5 and Bifidobacterium animalis ssp. lactis BB-12. Lipases were used to release free form of linoleic acid (LA) from walnut oil to create conditions favorable for CLA synthesis by the starter culture.

Ammonia Suppresses the Antitumor Activity of Natural Killer Cells and T Cells by Decreasing Mature Perforin.

Unlabelled: Immunotherapy revolutionized cancer treatment in the last decade. Both NK cells and T cells are key components of host immunity against malignant cells that are being extensively investigated in the field of cancer immunotherapy. While approaches have been developed to improve the antitumor activity of NK and T cells, the tumor microenvironment remains an obstacle to effective NK and T-cell-based therapies.
