Permeation of supercritical CO2 through dense polymeric membranes

, 2019
Supercritical carbon dioxide (scCO2) is used in the food industry as a water-extracting drying agent. Once saturated with water, the scCO2 needs to be regenerated. A promising way of drying scCO2 is by using H2O permeable membranes.

Advancing Upcycling and Regeneration of Spent LiFePO4: Failure Mechanisms and Recovery Strategies

Carbon Energy, EarlyView.
This review studies the failure mechanism to promote the upcycling regeneration of spent lithium iron phosphate (S‐LFP). It first summarizes the failure mechanisms of LFP batteries revealed via advanced characterization technologies and then explores the respective advantages and challenges of hydrometallurgy and direct regeneration methods.

Biomass‐Coupled HER System: A Strategy for Sustainable and Low‐Cost Hydrogen Production

Carbon Energy, EarlyView.
Pine wood is carbonized into a hierarchically porous biochar anode that undergoes carbon oxidation reaction, replacing the oxygen evolution reaction in alkaline water electrolysis. The resulting biomass‐coupled HER system converts water into hydrogen at low cell voltages, enabling low‐cost H2 production from renewable carbon resources. ABSTRACT Biomass‐

Conversion Between 2‐ and 3‐Dimensional Halogen‐Bonded Networks Formed From a Single N‐Oxide/Iodoalkyne Building Block

Chemistry – A European Journal, EarlyView.
Open halogen‐bonded networks have been prepared from building blocks that incorporate both iodoalkyne halogen bond donors and a pyridine‐N‐oxide halogen bond acceptor. An initially‐formed 3D network containing dioxane in its channels undergoes an unprecedented transition to a 2D material when crystals are exposed to diethyl ether.

A Methodology to Integrate Closed‐Cycle Heat Pumps into Batch Distillation Columns

Chemie Ingenieur Technik, EarlyView.
Batch distillation often cannot use vapor recompression due to contamination risks in food and pharma. This study proposes a design for integrating closed‐loop heat pumps using natural fluids. Results show significant energy savings, offering a sustainable alternative to traditional setups.
