Three-Dimensional Simulations of Magnetized Thin Accretion Disks around Black Holes: Stress in the Plunging Region

, 2008
We describe three-dimensional general relativistic magnetohydrodynamic simulations of a geometrically thin accretion disk around a non-spinning black hole. The disk has a thickness $h/r\sim0.05-0.1$ over the radial range $(2-20)GM/c^2$.

A Robust Dual‐mode Self‐Monitoring Battery Thermal Management System via Bilayer Structural Design

Advanced Functional Materials, EarlyView.
An adaptive dual‐mode material capable of both evaporative cooling and photothermal preheating is developed. It achieves a cooling efficiency of 53.9%, surpassing existing evaporative cooling counterparts, and a self‐monitoring capability, making it ideal for electric vehicles, portable electronics, and grid‐scale energy storage.

Kinematics of Cataclysmic Variables in the Solar Neighborhood in the Gaia Era

The Astronomical Journal
Using high-precision astrometric data from Gaia DR3 and updated systemic velocities from the literature, the kinematical properties of cataclysmic variables (CVs) were investigated. By constraining the data according to the total space velocity error and

The large-scale magnetic field of a thin accretion disk with outflows

, 2019
The large-scale magnetic field threading an accretion disk plays an important role in launching jets/outflows. The field may probably be advected inwards by the plasma in the accretion disk from the ambient environment (interstellar medium or a companion

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

OPEN CLUSTERS AND FIELD CEPHEIDS IN THE GALACTIC DISK – CONTRADICTIONS IN PROPERTIES

Odessa Astronomical Publications, 2013
The comparative analysis of the abundances of  α-process elements, elements of the  rapid and the slow neutron capture and iron in the open stellar clusters, field Cepheids, and also in red giants and dwarfs of the thin disk has been performed. The found

Patterning the Void: Combining L‐Systems with Archimedean Tessellations as a Perspective for Tissue Engineering Scaffolds

Advanced Functional Materials, EarlyView.
This study introduces a novel multi‐scale scaffold design using L‐fractals arranged in Archimedean tessellations for tissue regeneration. Despite similar porosity, tiles display vastly different tensile responses (1–100 MPa) and deformation modes. In vitro experiments with hMSCs show geometry‐dependent growth and activity. Over 55 000 tile combinations

Spatial hole burning in thin-disk lasers and twisted-mode operation

, 2018
Spatial hole burning prevents single-frequency operation of thin-disk lasers when the thin disk is used as a folding mirror. We present an evaluation of the saturation effects in the disk for disks acting as end-mirrors and as folding-mirrors explaining ...

Mechanically Tunable Bone Scaffolds: In Vivo Hardening of 3D‐Printed Calcium Phosphate/Polycaprolactone Inks

Advanced Functional Materials, EarlyView.
A 3D bone scaffold with osteogenic properties and capable of hardening in vivo is developed. The scaffold is implanted in a ductile state, and a phase transformation of the ceramic induces the stiffening and strengthening of the scaffold in vivo. Abstract Calcium phosphate 3D printing has revolutionized customized bone grafting.
