Synergetic Combination of Carbon Xerogels, Graphene Oxide and nano‐ZnO for Aqueous and Organic Supercapacitors

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.

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 ...

Bismuth‐Based Semiconductors in Photocatalytic CO2 Reduction: Catalysts, Progress, and Future Perspectives

Carbon and Hydrogen, EarlyView.
This review systematically summarizes research progress on bismuth‐based semiconductor photocatalytic materials in the field of CO2 reduction. It focuses on elucidating the mechanisms by which four modification strategies—including heteroatom doping, oxygen vacancy engineering, microstructural control, and heterostructure fabrication—regulate band ...

Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater

Chemie Ingenieur Technik, EarlyView.
This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...

Application of artificial neural network and general machine learning modelling on CO2 adsorption in moisture equilibrated South African high and medium rank coals

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the effect of moisture on CO2 adsorption in South African coals using both experimental and machine learning approaches. Three coal samples (SL, TN, and EM) with varying ranks (RoVmr: 3.49%, 1.26%, and 0.64%, respectively) were collected from different regions of South Africa.

Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers

The Canadian Journal of Chemical Engineering, EarlyView.
This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

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

Catalytic Hydrothermal Liquefaction of Polyethylene With Pt/C to Tune Product Selectivity

CleanMat, EarlyView.
Pt/C‐catalyzed hydrothermal liquefaction of polyethylene in supercritical water enables time‐dependent control of product selectivity, producing paraffin‐rich oils at shorter reaction times and aromatic‐enriched products at longer times without external hydrogen. ABSTRACT Hydrothermal liquefaction (HTL) represents a promising thermochemical pathway for
