Automatic Reaction Rate Method for the Determination of Vicinal Glycols with a Perchlorate Ion Selective Electrode [PDF]
An automatic potentlometric reaction rate method is described and shown to be simple, rapid and accurate for the determination of ethylene-, propylene-, and butylene glycol. The vicinal glycol Is oxidized with periodate, and the reaction rate is followed

Unsaturated biobased polyesters from bicyclic α‐pinene‐based diols
We present the synthesis of four biosourced unsaturated polyesters made from chiral terpene‐based diols and esters of renewable diacids. The resulting materials harbor a bicyclic pinene ring in their backbones which leads to enhanced thermal properties while still conferring susceptibility to enzyme hydrolysis for chains having a cis alkene.

The antimicrobial properties of three glycols, - propylene glycol, hexylene glycol, and 1,3-butylene glycol - against Candida albicans, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes A, Streptococcus mitis, and E. coli were studied in vitro. Within 20 h, 10% and 30% hexylene glycol in fresh tryptic soy broth were able to kill

Microbial Production of 2,3-Butylene Glycol from Cheese Whey [PDF]
Six microorganisms that produced acetoin or diacetyl or both from glucose were tested for the production of 2,3-butylene glycol from lactose. Bacillus polymyxa and Streptococcus faecalis gave positive results and were tested in unmodified wheys. Cottage cheese whey was unsatisfactory, but

ABSTRACT N‐vinylamides, especially noncyclic N‐vinylacetamide (NVA), have been used in various applications such as biomaterials, surfactants, and hydrogels. However, their potential to copolymerize with cyclic ketene acetal (CKA) to create degradable polymers is underexplored.

ABSTRACT This article presents a review of the recent findings on the combination of electrospun nanofibers and three‐dimensional (3D)‐printed structures for extracellular matrix (ECM) scaffolds for bone tissue engineering. We explore the synergy between electrospinning (ES), which produces highly porous, fibrous structures from materials like collagen

Chemical Recycling as a Tool for Enabling a Second Life for Polyesters
This review presents the elucidation of the life cycle of main polyesters, detailing end‐of‐life methods, with focus of solvolysis technologies, then an analysis of LCA and TEA on literature data, an original data analytic, and, finally, a current industrial mapping of the main processes with a critical perspective on the plastic life‐cycle ecosystem ...

This study shows that incorporating 5–10 wt.% Posidonia oceanica, with or without micro‐talc, in PBSA preserves thermal stability, modifying crystallization behavior, and maintains good filler dispersion and interfacial adhesion. Mechanical properties are moderately stiffened.
