Study on iron anchoring methods for magnetic biochar: Characterization, functional mechanism, and RBBR dye removal

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Magnetic biochar (MBC) is a novel bio‐metallic composite material with high potential in sustainable water cleaning. Iron anchoring is critical in forming iron‐based MBC and will fundamentally impact its characteristics and functionality in dye removal applications. However, the mechanism is not well‐revealed.

Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...

The Effect of Electrolyte pH and Impurities on the Stability of Electrolytic Bicarbonate Conversion

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
The performance of bicarbonate electrolysis is largely controlled by the electrolyte inlet pH, the distance between the membrane and electrode, and the impurities present in the electrolyte. By complexing trace metal ions with ethylenediaminetetraacetic acid (EDTA), stability can significantly be improved and longer term operation can be achieved ...

Biodegradation of oxidized regenerated cellulose

Carbohydrate Research, 1990
The in vitro solubilization and degradation of regenerated cellulose was studied under conditions which approximate those found in vivo, when the material is used as an adhesion barrier to assist normal wound repair. Factors affecting solubilization which were examined included the effects of serum or plasma, and the presence of hydrolytic enzymes ...

Regenerated cellulose-silk fibroin blends fibers

International Journal of Biological Macromolecules, 2008
Fibers made of cellulose and silk fibroin at different composition were wet spun from solutions by using N-methylmorpholine N-oxide hydrates (NMMO/H(2)O) as solvent and ethanol as coagulant. Different spinning conditions were used. The fibers were characterized by different techniques: FTIR-Raman, scanning electron microscopy, wide-angle x-ray ...

Oxidized Regenerated Cellulose Imitating Pelvic Abscess

Obstetrics & Gynecology, 2013
Oxidized regenerated cellulose is a topical hemostatic agent that is used commonly in abdominal and pelvic surgery. Although oxidized regenerated cellulose mimicking an abscess has been reported after different operations, little is known about its side effects after gynecologic surgery.Two women were diagnosed with postoperative abscess and intra ...

Oxidized Regenerated Cellulose for Hepatic Hemostasis

Archives of Surgery, 1963
Introduction Oxidized regenerated cellulose is a relatively recent addition to the surgeon's armamentarium for hemostasis. Its hemostatic and absorbable qualities have been attested to by several authors in recent articles. 1-5 There have also been several articles describing its chemical nature, the mechanism of solubility in human tissues, and ...
