ZrO2 Aerogel‐Supported Pd Nanoparticles for Photothermal CO2 Reduction

Advanced Science, EarlyView.
Nanoparticle‐based aerogels are promising catalysts for photothermal reactions due to optical transparency, high surface area, and low thermal conductivity. Here, we present deposition of Pd nanoparticles on ZrO2 aerogel granules by a wet‐impregnation approach.

Ion-Pair-Supercritical Fluid Extraction of Clenbuterol from Food Samples [PDF]

, 1995
Simultaneous ion-pair/supercritical fluid extraction (SFE) was investigated as an alternative to liquid solvent extraction for clenbuterol determination. Clenbuterol was extracted from diatomaceous earth and food matrices (feedstuff, lyophilized milk and

Supercritical fluid extraction of phenol compounds from olive leaves [PDF]

, 1998
A clean, highly selective supercritical fluid extraction (SFE) method for the isolation of phenols from olive leaf samples was examined. Total phenol extracts were determined using the Folin-Ciocalteu reagent. Dried, ground, sieved olive leaf samples (30

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 ...

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.
