Borate complexation-assisted capillary electrophoretic determination of ethylene glycol and propylene glycol using capacitively coupled contactless conductivity detection

Journal of Chromatography Open
A novel, fast, and reliable analytical method for determining ethylene glycol (EG) and propylene glycol (PG) using capillary electrophoresis (CE) with capacitively coupled contactless conductivity detection (C4D) is proposed.

One‐Component Carbon Dot Photoinitiator Enables High‐Fidelity Digital Light Processing 3D Printing With Improved Mechanical Resistance

Advanced Functional Materials, EarlyView.
Furfural carbon dots functionalized with acylphosphine oxide photosensitive groups (CD‐PO PI) demonstrate potential as one‐component photoinitiators for digital light processing (DLP) 3D printing. Compared to conventional diphenyl(2,4,6‐trimethylbenzoyl)phosphine oxide (TPO), CD‐PO PI offers improved printing resolution, resin toughness, and biological

Efficient synthesis and hydrolysis of cyclic oxalate esters of glycols [PDF]

Based on the mechanism postulated for the formation of the cyclic carbonates 3 in the reactions of glycols 1 with oxalyl chloride in the presence of triethylamine, we present here three efficient syntheses of the cyclic oxalates 2 of various glycols 1 by

A Selective Gas Chromatography–Tandem Mass Spectrometry Method for Quantitation of Ethylene and Diethylene Glycol in Paediatric Syrups

Heliyon
Ethylene Glycol (EG) and diethylene Glycol (DEG) are two contaminants known to cause various human health problems. These glycols might be present in drug syrups that are based on glycerol, sorbitol, or polyethylene glycol.

Spatially Controlled Embedded Bioprinting of Prevascularized Spheroids‐Containing Biopatch Enables Functional Skin Regeneration

Advanced Healthcare Materials, EarlyView.
A spatially controlled embedded bioprinting strategy enables precise engineering of prevascularized multicellular spheroids within skin‐derived dECM bioinks. Optimized spheroid size, composition, and spacing promote vascular maturation, paracrine signaling, and tissue integration, resulting in enhanced angiogenesis, blood perfusion, and functional skin

Oxidation of Ethylene Glycol and Glycolic Acid by Glycerol Oxidase

Bioscience, Biotechnology, and Biochemistry, 1995
A glycerol oxidase from Aspergillus japonicus oxidized ethylene glycol to glyoxal by the same reaction pathway as alcohol oxidases from methanol yeast. The optimum pH and temperature for the oxidation of ethylene glycol were around 7.0 and 40 degrees C, respectively. Those of glycolaldehyde were similar to those of ethylene glycol. The apparent Kms for

Facile Hydrogenolysis of Sugars to 1,2-Glycols by Ru@PPh₃/OPPh₃ Confined Large-Pore Mesoporous Silica

Tandem hydrogenation vis-à-vis hydrogenolysis of xylose to 1,2-glycols remains a major challenge. Although one-pot conversion of xylose to 1,2-glycols requires stringent conditions, a sustainable approach would be quite noteworthy.

Engineering Antigen Density on M13 Bacteriophage for Personalized Nanovaccine

Advanced Healthcare Materials, EarlyView.
Increasing antigen density on the phage capsid impacts phage uptake and antigen cross‐presentation by antigen‐presenting cells, leading to enhanced activation of antitumor CD8+ T cells in the draining lymph nodes. These activated CD8+ T cells subsequently recognize the antigen‐expressing tumors and mediate their specific cytotoxic killing, thereby ...
