Stellar Evolution Through the Red Supergiant Phase

Galaxies
Massive stars less massive than ∼30 M⊙ evolve into a red supergiant after the main sequence. Given a standard IMF, this means about 80% of all single massive stars will experience this phase.

3D Printing of Functional Mesoporous Silica Monoliths with Embedded Metal and MOF Components

Advanced Functional Materials, EarlyView.
This article presents the development of silica nanocage‐based nano‐inks tailored for digital light processing 3D printing, enabling automated additive manufacturing of mesoporous monoliths. Novel strategies for incorporating metal sites and inducing in situ growth of metal‐organic frameworks are introduced.

Electrically Binary and Ternary Convertible CMOS Inverter and Logic Gate Using Complementary Field‐Effect Transistors Based on Vertically Stacked MoS2/WSe2 n‐/p‐ Field‐Effect Transistors

Advanced Functional Materials, EarlyView.
In this work, a reconfigurable T‐CMOS inverter based on vertically stacked MoS2 and WSe2 MOSFETs with a gate‐tunable MoS2 resistor, enabling stable ternary logic, is demonstrated. The T‐CMOS inverter supports electrical switching between ternary and binary modes and is further extended to implement ternary NAND (NMIN) and NOR (NMAX) logic gates ...

Exploring the History of Stellar Mergers with Chemistry: Examining the Origins of Massive α-enriched Stars Using Carbon Isotope Ratios

The Astrophysical Journal
Recently discovered massive α -enriched (MAE) stars have surface chemistry consistent with members of the older, thick-disk Milky Way population but high masses (∼1.5–3 M _⊙ ) that suggest these stars are young.

CO2 Reduction on Copper‐Nitrogen‐Doped Carbon Catalysts Tuned by Pulsed Potential Electrolysis: Effect of Pulse Potential

Advanced Functional Materials, EarlyView.
This study demonstrates that pulsed potential electrolysis significantly improves CO2 reduction performance on copper‐nitrogen doped carbon electrodes. The formation of cationic copper sites and metallic clusters as a function of applied intermittent potential leads to notable selectivity changes compared to potentiostatic reduction.

Explosions in Roche-lobe Distorted Stars: Relativistic Bullets in Binaries

The Astrophysical Journal
State-of-the-art surveys reveal that most massive stars in the Universe evolve in close binaries. Massive stars in such systems are expected to develop aspherical envelopes due to tidal interactions and/or rotational effects.
