Discovery of a New Spectral Transition in Swift J0243.6+6124 in the Sub-Eddington Regime

The Astrophysical Journal
We have conducted a detailed spectral analysis of Swift J0243.6+6124 in its sub-Eddington regime, as observed by Insight-HXMT and NICER during a series of outbursts including the giant one in 2018, and discovered a new transition at L _t  ∼ 4.5 × 10 ^37 ...

Modeling High Mass X-Ray Binaries to Double Neutron Stars through Common Envelope Evolution

The Astrophysical Journal
Abstract We present detailed evolutionary simulations of wide binary systems with high-mass (8–20 M ⊙) donor stars and a 1.4 M ⊙ neutron star. Mass transfer in such binaries is dynamically unstable, and common envelope (CE) evolution is followed. We use a recently developed prescription to deal with CE

Atomic Layer Deposition in Transistors and Monolithic 3D Integration

Advanced Functional Materials, EarlyView.
Transistors are fundamental building blocks of modern electronics. This review summarizes recent progress in atomic layer deposition (ALD) for the synthesis of two‐dimensional (2D) metal oxides and transition‐metal dichalcogenides (TMDCs), with particular emphasis on their enabling role in monolithic three‐dimensional (M3D) integration for next ...

Tidal Interaction in High Mass X-ray Binaries

, 2009
Our aim is to investigate tidal interaction in High-Mass X-ray Binary stars in order to determine in which objects the rotation of the mass donors is synchronized or pseudosynchronized with the orbital motion of the compact companion.

Solvent‐Free Manufacturing of Multifunctional Gas Diffusion Electrode Architectures for Enhanced CO2 Conversion From Low‐Concentration Streams

Advanced Functional Materials, EarlyView.
A tandem gas diffusion electrode (GDE) leveraging hierarchically engineered microgranules enables efficient CO2 electroreduction under dilute CO2 conditions. A key innovation lies in the solvent‐free precision assembly of metal–organic‐frameworks, carbon nanotubes, and copper nanoparticles.

Intermediate Mass Black Holes in Accreting Binaries: Formation, Evolution and Observational Appearance

, 2004
We study the origin of the ultraluminous X-ray source M82-X1 in the nearby starburst galaxy M82. This X-ray source is of particular interest as it is currently the best candidate intermediate mass black hole; it is associated with a 54mHz quasi periodic ...

Revealing the Hidden Role of Cd in p‐Type Mg3Sb2: Enhanced Thermoelectric Performance by Grain Boundary Segregation Engineering

Advanced Functional Materials, EarlyView.
The hidden role of Cd segregation at grain boundaries is revealed in p‐type Mg3Sb2 by atom probe tomography and other advanced characterizations. Grain boundary Cd enrichment suppresses the SbMg+ hole‐killer formation and lowers potential barriers, enhancing electrical conductivity.
