Gas–liquid mass transfer enhancement in the presence of nanoparticles under slug flow in microreactors

AIChE Journal, EarlyView.
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.

Chelation Drives Surface Substitution in Hybrid‐MXenes

Angewandte Chemie, EarlyView.
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.

Preferential trading in agriculture: New insights from a structural gravity analysis and machine learning

American Journal of Agricultural Economics, EarlyView.
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

Adaptive Hydrogenation of Alkynes Using CO as a Molecular Trigger to Selectively Produce Alkanes or Z‐Alkenes

Angewandte Chemie, EarlyView.
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.
