Modulation of Local Environment for Selective Bicarbonate Conversion to Multi‐Carbon Products

open access: yesAdvanced Energy Materials, EarlyView.
Highly porous Cu electrode partially coated with an ionomer/carbon composite enables efficient conversion of bicarbonate to multi‐carbon products. By regulating the local reaction microenvironment, this strategy overcomes selectivity and reaction‐rate limitations, achieving Faradaic efficiencies of 43% for ethylene and 60% for total multi‐carbon ...

Synthesis of functionalized polyolefins in a new continuous bench‐scale reactor apparatus

open access: yesAIChE Journal, EarlyView.
Abstract In‐reactor functionalized polyolefins (FPOs), produced by molecular catalysts, are a new class of polymer materials with applications ranging from high performance adhesives to bitumen compatibilization. In this work, we disclose a procedure for the synthesis of FPOs in a new Continuous Bench‐scale Reactor Apparatus (COBRA).

The Role of Zn–Hf Site Proximity and Oxygen Vacancies for Methanol Formation Over ZnHfOx Catalysts Under CO2 Hydrogenation Conditions

open access: yesAngewandte Chemie, EarlyView.
ZnHfOx catalysts enable highly selective hydrogenation of CO2 to methanol over a wide range of Zn contents, as the Zn‐VO‐Hf active motif (VO = oxygen vacancy) exists not only in solid solution‐type ZnHfOx for low Zn contents (≤ 35 mol%), but also as HfOx cluster/single atom decorated ZnO surfaces for Zn contents > 95 mol%.

Embedding Chemistry and Pharmacy Into Sustainability

open access: yesAngewandte Chemie International Edition, EarlyView.
Chemistry and pharmacy provide products and processes that are indispensable for our high living standard. To understand their relationship with sustainability is important to allow them to contribute to sustainability in a sustainable manner. An integrated overview of green, circular, and sustainable chemistry and pharmacy is given and how they have t

Heat Transfer Fluids as Co‐Diluents in Localized High‐Concentration Electrolytes for High‐Rate Lithium Metal Batteries With Enhanced Safety

open access: yesAngewandte Chemie International Edition, EarlyView.
Two fluorinated ethers, commonly used as heat‐transfer fluids, are explored as co‐diluents in localized high‐concentration electrolytes (LHCEs) for lithium metal‐based batteries. The best‐performing ternary diluent blend boosts ion mobility and cuts overvoltages, thereby improving Coulombic efficiency and cycle life at ≥1 mA cm−2 in zero‐excess pouch ...

Exploring the Application of Waxes and Their Mixtures Oleogels in Ice Cream

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT The objective of this work was to produce ice cream using waxes oleogels, aiming to improve its nutritional value while maintaining its physical‐chemistry characteristics. Five ice cream formulations were manufactured using (1) milk fat, (2) canola oil, and (3–5) canola oil‐oleogels. The oleogels were produced with beeswax (BEW), carnauba wax (
