Activity Against Pythium insidiosum and Isolated Constituents of Cordia insignis Roots

Chemistry &Biodiversity, EarlyView.
This study investigates the roots of Cordia insignis in search of novel treatments for pythiosis, caused by the oomycete Pythium insidiosum. Seven compounds are isolated, including steroids, a saponin, a coumarin, a fatty acid, and a glycoside, the latter two are reported for the first time in the genus.

Entropy‐Controlled Exsolution of Highly Dispersed Nickel‐Based Active Metals From Spinel Oxide via Optimizing Metal‐Support Interaction for Dry Reforming of Methane

Carbon Energy, EarlyView.
The incorporation of transition‐metal elements into spinel oxides results in enhanced configurational entropy and increased metal‐support interaction, which continuously modulate the exsolution of nickel‐based active metal. The highly dispersed nickel‐based metal catalyst, formed through the entropy‐controlled strategy, demonstrates remarkable activity

Solvent‐Driven Pore Engineering in Coffee‐Derived Activated Hydrochar: Implications for Post‐Combustion CO2 Capture

Carbon Energy, EarlyView.
Solvent washing of coffee‐ground hydrochars produces activated carbons with tunable pore sizes while maintaining surface area. Removing non‐polar contaminants enhances microporosity, increasing CO2 uptake by 40%. Moderate pore sizes (9–12 Å) yield optimal CO2:N2 selectivity, whereas smaller pores reduce selectivity due to stronger interactions between ...

Integration of High‐p, Low‐T CO2 Electrolysis with Pressure Swing Adsorption Purification

Chemie Ingenieur Technik, EarlyView.
We evaluate a high‐p low‐T CO2 electrolysis (LTCE) cell with a pressure swing adsorption (PSA) to compare cascade vs. recycle operation. Although a cascade yields high CO selectivity but limited yield, a full recycle achieves near‐quantitative CO production, highlighting gas recycling as essential for LTCE/PSA systems.
