Supercritical CO2 Sorption Within Polymers Used in Medical Devices and Their Packaging

open access: yesJournal of Applied Polymer Science, EarlyView.
In situ CO2 sorption monitoring ensured the establishment of thermodynamic equilibrium in polymers used for medical devices and their packaging. All the studied polymers, except PETG, exhibited similar kinetic profiles, allowing the quantification of CO2 sorption and the resulting polymer swelling under thermodynamic equilibrium conditions. For PETG, a

Studies on the use of supercritical ammonia for ceramic nitride synthesis and fabrication [PDF]

open access: yes
The extractability of ammonia halides (including ammonium thiocyanate) formed as byproducts from the synthesis of Si(NH)2 via ammonolysis of the corresponding silicon tetrahalides using supercritical NH3 as the extraction medium was investigated.

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

open access: yesBatteries &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.

Regeneration of Modified Bentonite Loaded with Phenol Using Supercritical Fluids

open access: yesAdsorption Science & Technology, 2004
The desorption of phenol from organically modified bentonite (ODTMA–bentonite) using supercritical fluids was studied. Parameters such as pressure, temperature, supercritical fluid flow rate and co-solvent (entrainer) concentration were investigated. The

Ultrarelativistic black hole formation

open access: yes, 2013
We study the ultrarelativistic head-on collision of equal mass particles, modeled as self-gravitating fluid spheres, by numerically solving the coupled Einstein-hydrodynamic equations.

Strategic techniques for upgrading bio‐oil from fast pyrolysis: a critical review

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Pyrolysis has been the subject of extensive scientific research due to its potential application to various waste streams and byproducts from different production systems. One of its main products is the liquid fraction known as bio‐oil – a complex material composed of a wide variety of organic molecules and a significant water content.
