Flow characteristics and regime transitions in fluidization systems of Group C+ particles
Abstract Fine and ultrafine particles are attractive for fluidized bed reactors because their high surface area benefits catalytic processes, but their cohesive nature complicates regime characterization. Nanoparticle modulation improves the flowability of Group C powders, yet their bubbling to turbulent transition remains unclear.

Solid particles focusing, orienting, and de‐focusing in planar Poiseuille flow
Abstract Three‐dimensional, time‐dependent lattice‐Boltzmann simulations of neutrally buoyant particles in planar Poiseuille flow have been performed. The particles are spherical or cylindrical (the latter with a length over diameter ratios in the range 1/3 to 2) and have volume fraction ranging from virtually zero (one particle) to 0.15. The channel's

Chelation Drives Surface Substitution in Hybrid‐MXenes
We demonstrate ethylenediamine‐derived bidentate binding on Ti3C2 by controlled deprotonation of ─NH2 groups during reaction with Ti3C2Br2. XRD, XPS, ssNMR, STEM, DFT, and INS confirm the bidentate coordination and the superior stability of chelating modes, while AIMD reveals proton transfer and new surface imine–Ti bonding mode.

Abstract Nanofluids containing nanoparticles represent a promising solvent or reaction system for gas–liquid operations. Herein, the effect of nanoparticle (Al2O3 and SiO2) addition on gas–liquid slug flow pattern and mass transfer enhancement was investigated during CO2 absorption into water in microreactors.

One catalyst for two products: CO acts as a molecular trigger for adaptive alkyne hydrogenation using supported Pd nanoparticles. The catalyst reversibly switches between the formation of alkanes under H2 and Z‐alkenes under H2/CO for 37 structurally diverse alkynes.

Abstract Preferential trade agreements (PTAs) contain various non‐tariff provisions, yet identifying their trade effects remains challenging because these commitments are high‐dimensional and strongly correlated within agreements. We estimated a theory‐consistent structural gravity model with domestic flows for 26 agricultural subsectors over 1988–2017
