Photoactivity Enhancement of WO Photoanodes Using the Combined Effect of Plasmonic Au and Photoluminescent YO:Eu Nanoparticles.

The WO photoanode has great potential application for solar photoelectrochemical water oxidation due to suitable band edge positions with water oxidation potentials. However, it suffers from poor light absorbance in the visible region. Here, we use Eu-doped YO nanoparticles (NPs) in combination with plasmonic gold (Au) NPs to better utilize and adsorb photons from UV and visible regions of sunlight.

Hydrophobic and Luminescent Polydimethylsiloxane PDMS-YO:Eu Coating for Power Enhancement and UV Protection of Si Solar Cells.

Solar cells have been developed as a highly efficient source of alternative energy, collecting photons from sunlight and turning them into electricity. On the other hand, ultraviolet (UV) radiation has a substantial impact on solar cells by damaging their active layers and, as a result, lowering their efficiency. Potential solutions include the blocking of UV light (which can reduce the power output of solar cells) or converting UV photons into visible light using down-conversion optical materials.

Terbium-doped carbon dots (Tb-CDs) as a novel contrast agent for efficient X-ray attenuation.

Metal-doped carbon dots have attracted considerable attention in nanomedicine over the last decade owing to their high biocompatibility and great potential for bioimaging, photothermal therapy, and photodynamic therapy. In this study, we prepared, and for the first time, examined terbium-doped CDs (Tb-CDs) as a novel contrast agent for computed tomography. A detailed physicochemical analysis revealed that the prepared Tb-CDs have small sizes (∼2-3 nm), contain relatively high terbium concentration (∼13.

Inhibitory mechanism of O-methylated quercetins, highly potent β-secretase inhibitors isolated from Caragana balchaschensis (Kom.) Pojark.

Ethnopharmacological Relevance: Caragana has a standing history of implementation in Traditional Chinese Medicine (TCM). Most species of this genus have been explored for multi-functional purposes, such as promoting blood circulation and curing neuralgia, fatigue, migraine, arthritis, and vascular hypertension (Meng et al., 2009).

Effectiveness of cyclohexyl functionality in ugonins from Helminthostachys zeylanica to PTP1B and α-glucosidase inhibitions.

Ugonins are unique flavonoids with cyclohexyl motif from Helminthostachys zeylanica. Ugonins (1-6) from the target plant displayed significant inhibitions against both PTP1B (ICs = 0.6-7.
