We observed an enhanced atom-dimer loss due to the existence of Efimov states in a three-component mixture of 6Li atoms. We measured the magnetic-field dependence of the atom-dimer loss in the mixture of atoms in state |1> and dimers formed in states |2> and |3>, and found two peaks corresponding to the degeneracy points of the energy levels of |23> dimers and the ground and first excited Efimov trimers. We found that the locations of these peaks disagree with universal theory predictions, in a way that cannot be explained by nonuniversal two-body properties. We constructed theoretical models that characterize the nonuniversal three-body physics of three-component 6Li atoms in the low-energy domain.

High-Performance Porous Supports Based on Hydroxyl-Terminated Polysulfone and CO/CO-Selective Composite Membranes.

The scope of this work was to develop a thin-film composite (TFC) membrane for the separation of CO/CO mixtures, which are relevant for many processes of gas processing and gasification of carbon-based feedstock. Special attention was given to the development of highly permeable porous polysulfone (PSF) supports (more than 26,000 GPU for CO) since both the selective and support layers contribute significantly to the overall performance of the TFC membrane. The PSF porous support is widely used in commercial and lab-scale TFC membranes, and its porous structure and other exploitation parameters are set during the non-solvent-induced phase separation (NIPS) process.

Selected phenotypes of dried maca () hypocotyls and supercritical CO extract (USPlus) of saw palmetto () were used to determine their targeted, cytotoxic action in prostate cancer cells. Fingerprinting by HPLC-MS and PCA analysis showed compositional differences in glucosinolates, amides, macamides, and other alkaloids, which varied based on the color and the size of hypocotyls. These phytochemical differences translated into a higher antioxidant potential of red maca than black maca samples.

H and O evolutions occur simultaneously for conventional particulate photocatalytic overall water splitting (PPOWS), leading to a significant backward reaction and the formation of an explosive H/O gas mixture. This is an issue that must be addressed prior to industrialization of PPOWS. Here, a convenient, cost-effective, and scalable concept is introduced to uncouple hydrogen and oxygen production for PPOWS.

Preliminary studies suggest that creatine and guanidinoacetic acid (GAA) may function as moderate vasodilators, enhancing tissue oxygen saturation. However, the potential effects of this combination on brain oxygenation in humans remain unknown. The primary objective of this randomized controlled pilot trial was to assess cerebral blood oxygenation indices following a 7-day administration of a mixture containing creatine and GAA in healthy adults.

A series of seven new -phenyl BODIPY-pyrrolo[3,4-]pyridin-5-one conjugates were synthesized in one experimental step by using a Sc(III)-catalyzed Ugi-Zhu three-component reaction coupled to a cascade sequence ( Diels-Alder/-acylation/aromatization) as post-MCR functionalization process. Further experimental studies were performed behind understanding the fluorescence response toward viscosity. All compounds exhibited a linear response between increasing viscosity (DMSO and glycerol mixtures) and fluorescence intensity.
