A Machine Learning‐Driven Pore‐Scale Network Model Coupling Reaction Kinetics and Interparticle Transport for Catalytic Process Design

Advanced Science, EarlyView.
Designing catalytic processes in porous reactors requires resolving coupled multiscale reaction–transport phenomena. We develop a machine‐learning‐accelerated pore‐scale dual‐network model with kinetics (DNMK), which captures reaction kinetics, pore‐scale transport, and reactor‐level behavior.

Warped Reheating in Multi-Throat Brane Inflation

, 2005
We investigate in some quantitative details the viability of reheating in multi-throat brane inflationary scenarios by estimating and comparing the time scales for the various processes involved.

Desirable Pore Connectivity Effects in Multiscale Interactive Cobalt Centers with Asymmetric B/N‐Coordination Carbon for Promoting Zn‐Air Batteries

Advanced Science, EarlyView.
A bicontinuous constructed cobalt active centers/asymmetric B/N‐coordination carbon catalyst is developed, which the ZAB assembled with CoBNPCF‐900 air cathode exhibits ultralong stability (1706.6 h). The permeability simulations indicate that the catalytic active site is highly exposed to the electrolyte, guaranteeing a high catalytic efficiency ...

Boron Nitride Nanomaterials Trigger Immunomodulatory Effects in Human Broncho‐Epithelial Cells by Modulating Eicosanoid Lipid Signaling

Advanced Science, EarlyView.
This study demonstrates that BNNT exposure disrupts lipid homeostasis in bronchial epithelial cell cultures and activates eicosanoid lipid biosynthesis, producing inflammatory lipid mediators like leukotrienes. These effects are more pronounced in asthmatic cell cultures compared to healthy ones.

Strong gravitational lensing by wormholes

, 2019
We study strong gravitational lensing by a class of static wormhole geometries. Analytical approaches to the same are developed, and the results differ substantially from strong lensing by black holes, first reported by Bozza.

Wormhole solutions with a polynomial equation-of-state and minimal violation of the null energy condition

, 2020
This paper discusses wormholes supported by general equation-of-state , resulting in a significant combination of the linear equation-of-state and some other models. Wormhole with a quadratic equation-of-state is studied as a particular example.
