Numerical analysis of reaction-diffusion effects on species mixing rates in turbulent premixed methane-air combustion [PDF]

, 2009
The scalar mixing time scale, a key quantity in many turbulent combustion models, is investigated for reactive scalars in premixed combustion. Direct numerical simulations (DNS) of three-dimensional, turbulent Bunsen flames with reduced methane-air ...

Ionic Precursors Transformed Into Vinyl Acetate Synthesis Catalyst via Reaction‐Driven Restructuring

Advanced Functional Materials, EarlyView.
This work demonstrates that a simple physical mixture of Pd and Au ionic precursors, KOAc promoter, and SiO2 support can transform into a highly active vinyl acetate synthesis catalyst through reaction‐driven restructuring. The results highlight reaction‐induced restructuring as an innovative and sustainable catalyst design strategy.

Controlling Structure and Stability in Ultrathin Ti3C2Tx MXene Multilayers for Hydrogen Gas Barrier Applications

Advanced Functional Materials, EarlyView.
An ultrathin nanocomposite MXene‐based multilayer effectively blocks hydrogen permeation by presenting a tortuous, layered structure. When the MXene is layered with reduced graphene oxide modified with a polycation, the resulting nanocomposite retains its hydrogen gas barrier properties at temperatures as high as 400°C (permeability of 7.13 ± 0.09 × 10−
