Advanced Functional Materials, EarlyView.Potassium–sulfur batteries are investigated using UV–vis spectroscopy to track the evolution of potassium polysulfide species at elevated temperature. The study reveals sulfur radical anions as key intermediates and shows how solvent composition and cell design influence polysulfide stability, redox behavior, and cycling performance, providing insights

Spectroscopic binary frequency among CNO stars
The Astrophysical Journal Supplement Series, 1988 Les observations spectroscopiques de 35 etoiles de type OB ayant des anomalies de carbone, azote et oxygene sont presentees. Les vitesses radiales sont mesurees raie par raie pour chacune des etoiles. L'analyse statistique des resultats confirme que la frequence des binaires spectroscopiques de courte periode est plus grande chez les etoiles de type ...

Advanced Functional Materials, EarlyView.Mesoblends consist of a nanostructured polymer into which a second polymer is imbibed with a selective solvent. In this work, a solvent‐templatable pentablock terpolymer possessing a sulfonated midblock is modified with a hydrophilic polymer that is photocrosslinked in situ, yielding a hierarchical binetwork.

The period distribution of close binary systems
, 1979 The analysis of the period distribution of eclipsing and spectroscopic binary systems shows the presence of some secondary maxima, which cannot depend on selection effects. These secondary maxima are mainly due to late type stars, as can be seen from the

Chiral Phase Change Nanomaterials
Advanced Functional Materials, EarlyView.This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

THREE SPECTROSCOPIC BINARIES IN THE BRIGHT STAR CATALOG SUPPLEMENT
Revista Mexicana de Astronomía y Astrofísica, 2019 This paper presents spectroscopic orbits of three binaries, HD 121212, HD 148434 and HD 148912, with evolved primaries and periods of order a year, found in a survey of late-type stars listed in the Supplement to the Yale Bright Star Catalog. All the orbits were determined from observations made with the DAO 1.2-m telescope and coudé spectrograph ...

Microlensing search for extra solar planets
, 2015 Gravitational microlensing may be used to probe distant stars for planetary companions. The presence of a planet in the vicinity of a star acting as the lens may cause a short lived anomaly in the observed lightcurve of the lensing event.

A Holistic Stabilization of the Anode in Lithium‐Sulfur Batteries Through a Ternary Alloy Fusion
Advanced Functional Materials, EarlyView.LiTeAl anodes fabricated through a scalable thermal fusion technique holistically addresses the stability issues faced by lithium‐metal anodes in lithium–sulfur batteries. Aluminum forming a skeletal network with lithium suppresses dendrite growth and enhances energy density, while tellurium forming a robust SEI facilitates Li+‐ion flow.
