Rich‐Electronic Interface Promoting Hydrogen‐Bond Reversible Formation for Ultra‐Stable and Energy‐Efficient Catalytic CO2 Capture

Carbon Energy, EarlyView.
Bridging micro–macro scales, a biomass‐derived Ni@C interface creates electron‐rich sites and hydrogen‐bond proton‐relay pathways, tuning interfacial charge and reversible hydrogen bond to enhance carbon capture capacity. Verified by in situ spectroscopy, multi‐scale simulations, and long‐term industrial testing, this system enables low‐temperature and

Interfacial Electronic Coupling in the GeSe2/Volcanic‐Rock–Like Carbon Framework Activates Reversible Intermediate Conversion for High‐Rate Sodium Storage

Carbon Energy, EarlyView.
A combined sol–gel/solid‐state approach was developed to integrate GeSe2 with a “volcanic‐rock”–like carbon framework (C). C incorporation reactivates the otherwise irreversible intermediates Na2Ge2Se5 and Na2GeSe3, thereby suppressing irreversible Na+ consumption.

Challenges of Bio‐Syngas Conversion to High‐Value‐Added Liquid Chemicals and Fuels via COx Hydrogenation

Carbon Energy, EarlyView.
Converting biomass‐derived syngas into value‐added fuels and chemicals offers a promising route toward carbon neutrality, yet unfavorable H2/COx ratios, elevated CO2 levels, and trace impurities pose persistent obstacles. This review examines strategies spanning syngas conditioning, impurity‐tolerant catalyst development, and integrated process design,

Non‐Covalent Fluorine–Silica Anchoring of a Molecular Platinum(II) bis(NHC) Catalyst: Structure, Interface Control, and Hydrosilylation Activity

Chemistry – A European Journal, EarlyView.
A Pt(II) bis(NHC) complex is immobilized on mesoporous silica through directional F–Si interactions encoded in the ligand framework. Quantitative 19F{29Si} REDOR experiments and molecular dynamics simulations establish Å‐scale catalyst–support contacts and define the interfacial organization.

Development of a Mechanically Regenerating Desublimator for Freeze‐Drying Systems in the Food Industry

Chemie Ingenieur Technik, EarlyView.
Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.
