Improved Strength and Corrosion Resistance of Ti–50Zr Alloy Through Heat Treatment
Advanced Engineering Materials, EarlyView.This work systematically analyzes the effects of heat treatment on mechanical properties and corrosion behavior of Ti‐50Zr alloy produced via vacuum arc melting. Microstructure transforms from coarse lamellar α phase in as‐cast condition to fine and uniformly distributes acicular α′ phase in heat‐treatment state.

Modelling of W UMa-type variable stars
South African Journal of Science, 2009 W Ursae Majoris (W UMa)-type variable stars are over-contact eclipsing binary stars. To understand how these systems form and evolve requires observations spanning many years, followed by detailed models of as many of them as possible.

The Astrophysical JournalIndividual stars located near the caustics of galaxy clusters can undergo extreme magnification when crossing microcaustics, rendering them observable even at cosmological distances. Though most massive stars are likely to reside in binary systems rather

Advanced Functional Materials, EarlyView.PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

The Long-period Spectroscopic Orbit and Dust Creation in the Wolf–Rayet Binary System WR 125
The Astrophysical JournalSeveral long-period binaries with a carbon-rich Wolf–Rayet star and an OB star produce dust in their wind collisions. In eccentric binaries, this is seen most strongly near periastron passage.

Nano‐Patterned CuO Nanowire Nanogap Hydrogen Gas Sensor with Voids
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.Sub‐5‐ppb hydrogen (H2) detection and sub‐10‐s response and recovery times are achieved based on nano‐patterned polycrystalline CuO nanowires nanogap gas sensors with voids using electron‐beam lithography and unique annealing processes. Pre‐H2 annealing, void‐generating oxidation, and downscaled nanogap electrodes are key to improving the sensing ...

Binary stars are pairs of stars that are gravitationally bound, providing in some cases accurate measurements of their masses and radii. As such, they serve as excellent testbeds for the theory of stellar structure and evolution. Moreover, binary stars that orbit each other at a sufficiently small distance will interact during their lifetimes, leading ...
