A Demarcation Criterion for Hydrogen Burning of Millinovae
The Astrophysical JournalMillinovae are a new class of transient supersoft X-ray sources with no clear signature of mass ejection. They show similar triangle shapes of V / I band light curves with 1000 times fainter peaks than typical classical novae. Maccarone et al.

Optical studies of classical novae in outburst [PDF]
International Astronomical Union Colloquium, 1990 AbstractA nova is followed optically from preoutburst to postoutburst appearance. Photospheric and atmospheric observational data are explained qualitatively through the energy budget, apparent in super-Eddington, Eddington, and sub-Eddington states, and the particle fluxes, according to their role in Grotrian’s model.

Transitioning Formamide Solvothermal Syntheses of MOFs to Less Toxic Solvents
Chemistry – A European Journal, EarlyView.Metal‐organic Frameworks (MOFs) are commonly synthesized in toxic formamide solvents. This study investigates the synthetic factors required for effective removal of formamides across various classes of MOFs, providing a foundation for designing new sustainable MOF syntheses.

Chemistry – A European Journal, EarlyView.A series of structurally diverse exoglycals was synthesized using a modified Julia‐olefination approach from sugar‐derived precursors. These glycosidase transition‐state mimics were further diversified via CuAAC chemistry to yield triazole‐conjugated analogues.

Tuning Solvation Structures with KPF6 Additives for More Stable Lithium Metal Battery Cycling
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Introducing an optimal 0.1 m KPF6 additive into the conventional 1 m LiPF6‐EC/DEC electrolyte promoted small aggregate formation, enhanced Li+ transport, and facilitated a uniform SEI, thereby significantly improving the cycling stability of Li‖LiFePO4 cells. Uncontrolled dendrite growth and low Coulombic efficiency remain major challenges limiting the

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Spray‐flame synthesis enables highly flexible and scalable production of multinary and high‐entropy oxide nanoparticles due to high synthesis temperatures with subsequent quenching. Temperature‐dependent in situ diffraction of as‐synthesized materials clearly reveals entropy stabilization in rock salt lattices, while spinels—featuring tetrahedral and ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This work reports one‐pot synthesized novel zwitterionic polydopamine‐silica (ZSiPDA) nanofillers for fabricating PES hybrid ultrafiltration membranes with enhanced hydrophilicity, permeability, and antifouling performance. The optimized membrane achieved over 91% humic acid removal and showed strong potential for municipal wastewater treatment.
