Geochemical Analysis of Calcareous Shale of Baong Formation (North Sumatera Basin) as Potential Source Rock

open access: yesAceh International Journal of Science and Technology
This research is related to calcareous shale whose samples were obtained from surface data (outcrop). This rock outcrop is characterized as a rock rich in organic material and impermeable, so it is predicted to become a source rock of oil and gas ...

A Guideline to Evaluate Sorbent Performance for Atmospheric Water Harvesting

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Reporting guidelines for atmospheric water harvesting sorbents allow benchmarking between research groups across seven key performance indicators (KPIs). Beyond simple equilibrium values (such as capacity or maximum water uptake), these KPIs validate sensitivity, reversibility, regeneration conditions, chemical stability, kinetics, and water quality ...

Emergent Chemical Reactivity and Complexity of RNA Condensates

open access: yesAngewandte Chemie, EarlyView.
RNA condensates capable of substrate enrichment and catalysis modulate their environment. Could this start a catalytic selection loop or evolution? Abstract The RNA world hypothesis posits the existence of life‐like assemblies that consisted mostly of RNA.

Current Landscape: Use of Supercritical CO2 in the Wood Industry

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The application of supercritical carbon dioxide (scCO2) to successfully dewater as well as extract resin from wood is becoming increasingly popular due to its greener and less energy‐intensive approach. With world focus shifting to developing methods with greater efficiency while decreasing harm to the environment, scCO2 applications have begun to set ...
