Gas Sensing With Aerogels: A Critical Review on Structure‐Property Correlations and Performance Optimization

Advanced Science, Volume 13, Issue 47, 24 August 2026.
With high specific surface area, and adjustable interface, aerogel provides a multi‐functional platform for gas sensing. This review systematically links structural parameters (specific surface area, pore size, heterojunctions) to sensing metrics (sensitivity, selectivity, stability), critically evaluates optimization strategies, and outlines future ...

CFD modeling and sensitivity‐guided design of silicon filament CVD reactors

AIChE Journal, Volume 72, Issue 8, August 2026.
Abstract Filament‐based chemical vapor deposition (CVD) for silicon (Si) coatings is often treated as an adaptation of planar deposition. But this overlooks fundamental shifts in transport phenomena and reaction kinetics. In filament CVD, the filament acts as a substrate, heat source, and flow disruptor simultaneously. In this work, we ask: What really

ParamNet: A Physics‐Guided Deep Learning Framework for Intelligent Self‐Inversion of Vacuum Optical Levitation Systems

Advanced Intelligent Systems, Volume 8, Issue 8, August 2026.
A physics‐guided deep learning framework, ParamNet, is introduced for the intelligent self‐inversion of vacuum optical tweezers. By fuzing dual‐branch time–frequency features with physical dynamical constraints, it achieves high‐accuracy calibration of trap parameters from short‐window, low‐frequency trajectories, outperforming traditional methods ...

The Role of Native Binder in Controlling the Polytetrafluoroethylene Distribution in Gas Diffusion Layers for Proton Exchange Membrane Fuel Cells

Fuel Cells, Volume 26, Issue 4, August 2026.
ABSTRACT Gas diffusion layers (GDLs), a critical component in H2${\rm H}_{2}$/O2${\rm O}_{2}$ proton exchange membrane fuel cells (PEMFCs), are commonly treated with polytetrafluoroethylene (PTFE) for controlling hydrophobicity. However, the influence of the GDL's native microstructure on the final PTFE spatial distribution is still poorly understood ...

The use of activated carbon derived from spent coffee grounds as a reusable, sustainable, and effective solution for the removal of butylparaben from water

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 8, Page 1547-1558, August 2026.
Abstract BACKGROUND Parabens, including butylparaben (BP), are widely used as antimicrobial preservatives in food, cosmetics, and pharmaceuticals, yet are poorly removed by conventional water treatment processes and pose potential risks to aquatic life and human health.

Hydraulic reconstruction of catastrophic drainage from the Late Glacial, Lake Fraser, British Columbia, Canada

Journal of Quaternary Science, Volume 41, Issue 6, Page 873-887, August 2026.
ABSTRACT Glacial Lake Fraser, which formed in British Columbia against the retreating Cordilleran Ice Sheet, stored ~520 km3 of water before its near‐total drainage into the Salish Sea during an outburst flood event. Despite the impact of the outburst flood on sediment transport and landscape evolution in the Fraser River valley, its peak discharge and

Static and Dynamic Analysis of Porous Gas Bearings Lubricated With Air, Refrigerant R‐134a, Helium and Hydrogen

Lubrication Science, Volume 38, Issue 5, Page 301-326, August 2026.
ABSTRACT Porous gas bearings (PGBs) enable high‐speed, oil‐free operation in modern rotating machinery. This study develops a coupled thermo‐hydrodynamic (THD) model for a cylindrical porous gas bearing lubricated with four working fluids—air, R‐134a, helium and hydrogen.

A novel ultra-high vacuum diffusion setup to study Knudsen diffusion

Reaction Chemistry & Engineering
An ultra-high vacuum setup was conceived to study Knudsen diffusion in channels with varied geometrical characteristics that can be modified using 3D printing. This new experimental methodology aids to gain insight into diffusion in nanoporous media.

Using Thermodynamics and Microstructure to Mitigate Overfitting in Pellet Reduction Models

steel research international, Volume 97, Issue 8, Page 4097-4107, August 2026.
A in time and space discretized, thermodynamically sound model for direct reduction of iron oxide pellets is described. The number of fitting parameters is drastically reduced compared to existing models. Nevertheless, fitting kinetic parameters based on conversion degree data alone leads to overfitting, which can be mitigated by correlating the ...
