Advanced Science, EarlyView.The study develops a H•/H– transfer strategy enabling efficient hydrocyclization/defluorination of CF3‐acrylamides to synthesize Seletracetam derivatives with gem‐difluoroalkenes. Mechanistic studies reveal distinct pathways: the NiII‐H/PhSiH3 system operates through a hydrogen atom transfer process, while the 1,4‐Michael addition of H– appears to be ...

Runaway OB Stars in the Small Magellanic Cloud III. Updated Kinematics and Insights on Dynamical vs. Supernova Ejections [PDF]
arXivWe use the kinematics of field OB stars to estimate the frequencies of runaway stars generated by the dynamical ejection scenario (DES), the binary supernova scenario (BSS), and the combined two-step mechanism. We update the proper motions for field OB and OBe stars in the Small Magellanic Cloud (SMC) using Gaia DR3.

A Novel Ti12‐Based Metal‐Organic Framework for Photocatalytic Hydrogen Evolution
Advanced Energy Materials, EarlyView.MIP‐209(Ti) is a new microporous MOF built up from Ti₁₂O₁₅ clusters and substituted terephthalate linkers, enabling isoreticular chemistry and clusters tunability for photocatalytic applications. Cr3⁺ doping (≤5 at%) on Ti‐oxoclusters drastically enhances water stability and boosts hydrogen production from water under simulated solar light irradiation.
