Summary: Type I X-ray bursts are the result of unstable thermonuclear burning on the surface of a neutron star, resulting in the release of energetic X-ray photons. These bursts interact with the surrounding accretion disk, increasing the accretion rate. By analyzing two photospheric radius expansion bursts in 4U 1636-536, it was found that the spectral fitting can be improved by considering enhanced persistent emission or reflection from the accretion disk. Evidence suggests that both Poynting-Robertson drag and disk reflection occurred during these bursts, and the disk reflection may contribute up to 20-30% of the total burst emissions.

Summary: This study investigates the interplay between a bright photospheric radius expansion (PRE) burst and persistent emission in 4U 1608-52. The findings indicate that the burst emission can be either enhanced preburst/persistent emission or the Comptonization of the burst emission by the corona/boundary layer. The temporal evolution of the NS surface emission shows a plateau and then a rise until the photosphere touches down on the NS surface, resulting in a flux peak.

The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
