Exploring molecule-surface interactions of urania IR spectroscopy and density functional theory.

Within the framework of surface-adsorbate interactions relevant to chemical reactions of spent nuclear fuel, the study of actinide oxide systems remains one of the most challenging tasks at both the experimental and computational levels. Consequently, our understanding of the effect of their unique electronic configurations on surface reactions lags behind that of d-block oxides. To investigate the surface properties of this system, we present the first infrared spectroscopy analysis of carbon monoxide (CO) interaction with a monocrystalline actinide oxide, UO(111).

Study of rutile TiO(110) single crystal by transient absorption spectroscopy in the presence of Cecations in aqueous environment. Implication on water splitting.

Cecations are commonly used as electron acceptors during the water oxidation to Oreaction over Ir- and Ru-based catalysts. They can also be reduced to Cecations by excited electrons from the conduction band of an oxide semiconductor with a suitable energy level.

Monitoring the Lifetime of Photoexcited Electrons in a Fresh and Bulk Reduced Rutile TiO Single Crystal. Possible Anisotropic Propagation.

Defects (oxygen vacancies and interstitial cations) in oxide semiconductors have recently been invoked as a key property behind increased photocatalytic reaction rates. In this work, we have monitored by transient absorption spectroscopy (TAS) excited electrons in the conduction band decaying into the invoked traps to extract their lifetime using a rutile single crystal instead of the more conveniently used powder homologue. This is preferred in order to rule out grain boundary, degree of crystallinity, and size effects among other parameters that would obscure the results.

Tools for measuring individual self-care capability: a scoping review.

Background: Our ability to self-care can play a crucial role in the prevention, management and rehabilitation of diverse conditions, including chronic non-communicable diseases. Various tools have been developed to support the measurement of self-care capabilities of healthy individuals, those experiencing everyday self-limiting conditions, or one or more multiple long-term conditions. We sought to characterise the various non-mono-disease specific self-care measurement tools for adults as such a review was lacking.

Exploring the photodynamic profile of laser-generated exciplex from a conjugated polymer.

In this work, we investigated the impact of the concentration on the spectral and amplified spontaneous emission spectra (ASE) of a conducting polymer of poly(2,5-di(3,7-dimethyloctyloxy) cyanoterephthalylidene) (PDDCP) in tetrahydrofuran (THF). The findings demonstrate that the absorption spectra exhibited two peaks at 330 and 445 nm across the concentration range (1-100 µg/mL). Irrespective of the optical density, altering the concentrations did not affect the absorption spectrum.

Structural Insights into Phosphorylation-Mediated Polymerase Function Loss for DNA Polymerase Bound to Gapped DNA.

DNA polymerase β is a member of the X-family of DNA polymerases, playing a critical role in the base excision repair (BER) pathway in mammalian cells by implementing the nucleotide gap-filling step. In vitro phosphorylation of DNA polymerase β with PKC on S44 causes loss in the enzyme's DNA polymerase activity but not single-strand DNA binding. Although these studies have shown that single-stranded DNA binding is not affected by phosphorylation, the structural basis behind the mechanism underlying phosphorylation-induced activity loss remains poorly understood.
