POLYETHYLENE GLYCOL DERIVATIVES AND THE PHASE-TRANSFER CATALYSIS [PDF]
, 1988 The phase-transfer catalyst efficiency of polyethylene glycols were proven and analysed. The stability of their sodium complexes increases with the length of chain while the lipophilicity decreases. As a result the best phase-transfer catalyst PEO-

Absorption of polyethylene glycols by plants and their effects on plant growth
, 1970 Summary A study was made of polyethylene glycols (PEG) as osmotica to decrease the water potential of culture solutions for studies of higher plant response to water stress.

Degradation of ethylene glycol and polyethylene glycols by methanogenic consortia
Applied and Environmental Microbiology, 1983 Methanogenic enrichments capable of degrading polyethylene glycol and ethylene glycol were obtained from sewage sludge. Ethanol, acetate, methane, and (in the case of polyethylene glycols) ethylene glycol were detected as products.

Intraoral Drug Delivery: Bridging the Gap Between Academic Research and Industrial Innovations
Advanced Functional Materials, EarlyView.Intraoral drug delivery offers a promising route for systemic and localized therapies, yet challenges such as enzymatic degradation, limited permeability, and microbial interactions hinder efficacy. This figure highlights innovative strategies—mucoadhesive materials, enzyme inhibitors, and permeation enhancers—to overcome these barriers.

New polymers for phase partitioning [PDF]
The synthesizing of several polyethylene glycols having crown ethers attached is reported. This work led to the identification of three new polymer types which promise to be more effective at selectively binding specific cell types. Work was completed on

Application of a mixture of glycol polyethylenes for the preparation of microcorrosion casts - an observation [PDF]
, 2002 Preparation of microcorrosion casts that can be used for observation in SEM is a laborious, time-consuming procedure. The authors paid particular attention to the process of dissection of the microcorrosion casts. This prompted the authors to reconstruct

Influence of ultrafiltration membrane characteristics on adsorptive fouling with dextrans [PDF]
, 2005 This paper presents a detailed investigation of fouling mechanisms for ultrafiltration membranes with polysaccharides obtained by studying membrane–solute (static adsorption) and membrane–solute–solute interactions (ultrafiltration (UF)).

Tunable Thermoshrinkable Hydrogels for 4D Fabrication of Cell‐Seeded Channels
Advanced Functional Materials, EarlyView.A thermoresponsive polymer with methacrylate groups for photo‐cross‐linking, based on polyethylene glycol, N‐isopropylacrylamide, and 2‐hydroxyethyl acrylate is synthetized to yield hydrogels that shrink upon temperature increase. The new polymer enables the fabrication of cell‐laden perfusable channels with diameters below 200 µm by combining ...
