Tie-layer and polyurethane formulations with embedded enzymes for on-demand degradable adhesives

Angela Romano, Antonella Rosato, Laura Sisti, Giulio Zanaroli et autres

Plastic waste management is based on recycling or the use of biodegradable alternatives to recalcitrant petroleum-based plastics. Although both approaches have progressed in response to pressing environmental concerns, the wide variety of plastic materials requires specialized recycling technologies. Multilayer packaging, for instance, …

1616 High-performance hydraulic fluidshydraulic fluid from vegetable oils

Svajus Asadauskas, Asta Grigucevičienė, Rolf Luther

Hydraulic fluids (HFs) are the second largest lubricant group behind engine oils. Alkali-refined rapeseed, canola and other vegetable oils can be used as their basestocks, but the performance is often inferior. Typically, oxidative stability, low-temperature fluidity and ester linkage hydrolysis are the …

Viscometry, volatility and stability of deep eutectic solvents from betaine

Dalia Bražinskienė, Tadas Matijošius, Svajus Asadauskas

Deep eutectic solvents can be formed from solids without any reaction or ionic exchange. Recently, natural deep eutectic solvents (NADES) are gaining popularity in extraction, lubrication or cooling, in particular betaine-based ones. A series of betaine formulations with xylitol and glycerol as …

Antifrictional Effects of Group IVB Elements Deposited as Nanolayers on Anodic Coatings

Tadas Matijošius, Giedrius Stalnionis, G. Bikulčius, Sigitas Jankauskas et autres

The utilization of anodized aluminum (Al) components would contribute greatly to combat against dry friction if good tribological properties could be attained. Despite its hardness, the wear rate of anodic coatings presents a major problem in many applications, including automotive, aerospace and …

Time–temperature superposition for kinetic mapping of solventless autocatalytic addition of diisocyanates and macrodiols

Svajus Asadauskas, Paulina Nemaniutė, Dalia Bražinskienė, Olegas Eicher‐Lorka et autres

The migration of chemicals from polyurethane (PUR) is a concern in many applications, such as adhesives for food packaging. Low molecular weight catalysts, which are prone to migration, need to be eliminated from PUR, in particular those containing Sn or other metals. …
