Preparation of Pectin Aerogels From Flaxseed and Evaluation of Their Potential as Hemostatic Agents: Water Absorption Characteristics

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Flaxseed has been used extensively to extract flaxseed oil and drugs used for breast cancer treatment. Flaxseed contains a considerable amount of pectin in addition. We extracted pectin from flaxseed and prepared pectin aerogels by the steps of de‐esterification, gelation, solvent exchange and supercritical CO2 drying.

Characterization of Non-Equilibrium Condensation of Supercritical Carbon Dioxide in a de Laval Nozzle

, 2017
On a ten-year timescale, Carbon Capture and Storage could significantly reduce carbon dioxide (CO 2 ) emissions. One of the major limitations of this technology is the energy penalty for the compression of CO 2 to supercritical conditions, which can ...

Combined Foaming and Surface Structuring of Polymers With Supercritical Carbon Dioxide (scCO2) Applying an Incomplete Saturation Strategy

Journal of Applied Polymer Science, EarlyView.
Combined foaming and structuring of polymer samples by processing with supercritical CO2 leads to nano‐ and microstructured surfaces on top of perfectly white polymer sheets. ABSTRACT Supercritical carbon dioxide (scCO2) is a widely applied solvent utilized in many physical–chemical processes, including the foaming or structuring of polymers.

Design of a silica-aerogel-based cosmic dust collector for the Tanpopo mission aboard the International Space Station

, 2014
We are developing a silica-aerogel-based cosmic dust collector for use in the Tanpopo experiment to be conducted on the International Space Station. The mass production of simple two-layer hydrophobic aerogels was undertaken in a contamination-controlled

Unlocking the Potential of Electrolyte Recovery from Battery Waste: A Promising Path to Sustainable and Safe Li‐Ion Batteries

Batteries &Supercaps, EarlyView.
Due to several challenges, electrolyte recovery from spent battery waste has been less explored compared to electrode materials. This study presents various strategies for recovering electrolytes from spent battery waste. Electrolyte recovery can prevent hazardous chemicals from being released into the environment.
