Characterizing flow of pressurized CO2 through micro-orifice for atomization applications: Experiments and CFD modelling

Journal of CO2 Utilization
Improving therapeutic efficacy of newly developed drugs remains a major challenge for the pharmaceutical industry. Spray drying based on atomization using high pressure or supercritical CO2 has been shown to be effective in improving therapeutic ...

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

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.

A Continuous Extraction and Pumpless Supercritical CO2 Drying System for Laboratory-Scale Aerogel Production

Gels, 2016
Production of aerogels starts with solution chemistry and may end with supercritical carbon dioxide drying, which both require a specialized system. Here we present a complete aerogel production system that was developed and used in our laboratory over ...

Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.

Comparative Study of Microwave-Assisted and Supercritical Drying for the Synthesis of Highly Porous Silica Aerogel: A Promising Adsorbent for Phenol Removal from Wastewater [PDF]

Iranian Journal of Chemistry & Chemical Engineering
The removal of phenol from wastewater is crucial because of its harmful influences on human health, soil quality, and aquatic ecosystems. Among the different methods used for phenol removal, adsorption has gained popularity as an affordable and effective

Effect of Loops on the Vibrational Spectrum of Percolation Network

, 1993
We study the effects of adding loops to a critical percolation cluster on the diffusional, and equivalently, (scalar) elastic properties of the fractal network. From the numerical calculations of the eigenspectrum of the transition probability matrix, we
