A Simple Regeneration Process Using a CO2‐Switchable‐Polarity Solvent for Cellulose Hydrogels

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The effect of transformation of the anion chemical structure on cellulose solubility by flowing CO2 gas into aqueous pyrrolidinium hydroxide solutions was investigated. The changes in anion structure allowed for the modulation of cellulose solubility in aqueous pyrrolidinium hydroxide solutions, thus establishing a simple and safe cellulose ...

Detection of Nitazenes in the Illicit Drug Supply Utilizing Precursor Ion Scan Methods With Paper Spray Mass Spectrometry

Drug Testing and Analysis, EarlyView.
Nitazenes are increasingly present in the illicit drug supply, complicating harm reduction efforts. We have developed a rapid, nontargeted precursor ion scan method to detect emerging nitazenes in real‐world opioid samples. The method identified multiple nitazenes, often replacing pharmaceutical opioids or mixed with fentanyl and benzodiazepines ...

Extraction of Cellulose and Microcrystalline Cellulose from Kenaf

Jurnal Kejuruteraan, 2020
Bast and core of kenaf which categorized as agriculture residues were used in the extraction of cellulose due to its lignocellulosic nature. In this study, cellulose was extracted from the raw kenaf by using 10% alkaline peroxide pre-treatment followed by extraction process at 85 °C using the combination of 20% (v/v) formic acid and 10% (v/v) hydrogen ...
