Application of lattice Boltzmann method to solution of viscous incompressible fluid dynamics problems

open access: yesНаучно-технический вестник информационных технологий, механики и оптики
The possibilities of simulation of viscous incompressible fluid flows with lattice Boltzmann method are considered. Unlike the traditional discretization approach based on the use of Navier–Stokes equations, the lattice Boltzmann method uses a mesoscopic

Interfacial Synergy in a Band‐Aligned Low‐Dimensional Heterojunction Toward Broadband Photodetection

open access: yesAdvanced Science, EarlyView.
Monolithically integrating sensing and communication, a Ta2NiSe5/Sb2Te3 heterojunction achieves visible‐to‐near‐infrared photovoltaics with high‐speed terahertz photo‐thermoelectric detection at room temperature. By engineering a Type‐II van der Waals heterojunction, we overcome the intrinsic spectral limitations and disparate physical requirements of ...

Pt Single‐Atom Activates Surface Lattice Oxygen for Enhanced Acetone Detection Mediated by the MvK Mechanism

open access: yesAdvanced Science, EarlyView.
A Pt single‐atom‐loaded CuO sensing material is developed for acetone detection, demonstrating remarkably enhanced sensing performance. The introduction of Pt single atoms effectively activates the lattice oxygen of the CuO support. A new sensing mechanism based on the Mars‐van Krevelen catalytic mechanism is proposed, offering new insights into the ...

In Situ Quantization with Memory‐Transistor Transfer Unit Based on Electrochemical Random‐Access Memory for Edge Applications

open access: yesAdvanced Science, EarlyView.
By combining ionic nonvolatile memories and transistors, this work proposes a compact synaptic unit to enable low‐precision neural network training. The design supports in situ weight quantization without extra programming and achieves accuracy comparable to ideal methods. This work obtains energy consumption advantage of 25.51× (ECRAM) and 4.84× (RRAM)

Sustainable KCl‐Assisted PbI2 Recycling for High‐Performance Quantum Dot Solar Cells

open access: yesAdvanced Science, EarlyView.
An additive‐assisted lead recycling strategy is developed by introducing trace KCl during PbI2 recrystallization from spent lead‐acid batteries. KCl regulates crystallization and impurity removal, yielding high‐purity PbI2 and enabling the formation of colloidally stable PbS and CsPbI3 quantum dots.

Regularized fluctuating lattice Boltzmann model

open access: yesThe Journal of Chemical Physics
We introduce a regularized fluctuating lattice Boltzmann model (Reg-FLBM) for the D3Q27 lattice, which incorporates thermal fluctuations through Hermite-based projections to ensure compliance with the fluctuation–dissipation theorem. By leveraging the recursive regularization framework, the model achieves thermodynamic consistency for both hydrodynamic

Outstanding 1200 °C Oxidation Resistance in a Novel Multi‐Principal Element Alloy via Lattice Distortion‐Induced Diffusion Suppression

open access: yesAdvanced Science, EarlyView.
The unique lamellar structure of the eutectic alloy promotes selective oxidation of Al initially, while lattice distortion‐induced diffusion suppression slows oxide growth during steady state. Combining these strategies, a Multi‐Principal Element Alloy with excellent oxidation resistance at 1200℃ was designed.

Vacancy‐Suppressed Garnet Electrolytes for Durable Solid‐State Batteries

open access: yesAdvanced Science, EarlyView.
A Li/O‐rich sintering strategy effectively suppresses intrinsic lithium and oxygen vacancies in cubic garnet electrolytes, yielding a dense and stable microstructure. The vacancy‐controlled electrolyte exhibits enhanced interfacial and air stability, enabling long‐term solid‐state battery cycling and providing a general design principle for defect ...
