1 day ago · Nonlinear optical (NLO) coherent light sources are widely applied in many areas of science and technology. As the core medium, the NLO material is required to have a wide transparent range, a large NLO response, and a high laser damaged threshold (LDT). It is common knowledge that langasite (La3Ga5SiO14, LGS) crystal has an underdeveloped second-harmonic generation (SHG) coefficient and a small birefringence, which seriously restrict its application in the NLO field, despite that it has a ...

Tropical cyclone rainfall significantly impacts coastal communities, primarily through inland flooding. Leveraging 19 years of hourly satellite observations of ...
3 days ago · The activity of HDAC8 is negatively regulated by K202 acetylation, a reversible modification that undergoes regulation throughout the cell cycle. In response to external stress stimuli, an increased HDAC8-K202 acetylation level mediated by Tip60 causes elevated SMC3 acetylation, which may lead to cell cycle arrest.

4 days ago · Catalytic oxidation of benzyl C-H bonds and sulfides from fuel oils stands as an attractive proposition in the quest for clean energy, yet their simultaneous oxidation with a singular, economically friendly catalyst is not well established. In this work, the combination of a cobalt(II) porphyrin ligand with 2-pyridinecarboxaldehyde and ZnII yielded a Zn8L6 cage (Co cube). The three-dimensional conjugated structure effectively enhances energy transfer efficiency, enabling the Co cube to show ...
3 days ago · Dark photon is a new gauge boson beyond the Standard Model as a kind of dark matter (DM) candidate. Dark photon dark matter (DPDM) interacts with electromagnetic fields via kinetic mixing, implicating an approach to give a constraint with extragalactic very high energy (VHE) sources.
