Multi‐Scale Bionic Structure Constructs Biomass Flame‐Retardant Thermal Insulation Foam Material

Advanced Science, EarlyView.
Inspired by mussel adhesion and hierarchical brick‐and‐mortar architectures, a cellulose‐based biomimetic foam is constructed by anchoring bentonite nanosheets onto a polydopamine‐decorated cellulose nanofiber network. The resulting foam combines low thermal conductivity with intrinsic flame retardancy and full biodegradability, presenting a ...

Decellularised tissues obtained by a CO2-philic detergent and supercritical CO2

European Cells and Materials, 2018
Tissue decellularisation has gained much attention in regenerative medicine as an alternative to synthetic materials. In decellularised tissues, biological cues can be maintained and provide cellular environments still unmet by synthetic materials. Supercritical CO2 (scCO2 ) has recently emerged as a promising alternative decellularisation technique to

Advancements in CO2 Capture Technologies: A Review of Amine Absorption and Alternative Methods for Post‐Combustion Integration

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Carbon capture technologies are poised to become one of the primary focuses regarding the achievement of net‐zero emissions by the year 2050. In these technologies, particular attention is given to post‐combustion CO2 capture, which is more easily implemented at existing power stations and other industries.

Carrying Gold in Supercritical CO2 [PDF]

Gold Bulletin, 1999
A series of fluorinated calixarene derivatives, with lower rim sulfur-donor atoms, were synthesized and studied for the sequestration of gold using supercritical fluid extraction. Following temperature and pressure optimization and using extracts collected in methyliso-butyl ketone, analysis by flame atomic absorption spectrometry reveals that Au(III ...

Fabrication of Polypropylene/CNF Composite Foam by Foam Extrusion With Chemical Blowing Agent

Journal of Applied Polymer Science, EarlyView.
Polypropylene/CNF composite foams were fabricated by a foam extrusion process using a chemical foaming method. The addition of CNFs resulted in finer and higher‐density cell structures, even at low chemical blowing agent concentrations. Furthermore, X‐ray CT and SEM observations revealed a unique spike‐like cell structure generated by the penetration ...
