Polymers for KrF 248 nm Nanosecond Laser Micromachining
… of eleven different kinds of commercial plastic films with different chemical structures and thermal properties. Chapters 3 and 4 discuss the synthesis and characterisation of chromophore functionalised poly(methyl methacrylate) and polyurethanes. The hypothesis for this section is based …

Characterisation and plastic-degrading potential of plastisphere-associated microorganisms
The versatility and affordability of plastics have contributed to their largely unrestricted production, increasing from two million tons (Mt) in 1950 to roughly 400 Mt per annum in 2022. Consequently, plastic waste is accumulating in the environment, where its degradation is slow, impacting …

Investigations of the destructive behavior, and method for control of the lesser mealworm, Alphitobius diaperinus (Panzer), (Coleoptera: Tenebrionidae)
… pits into the insulation. Insecticide sprays, plastic films, paint barriers applied to the surface of extruded polystyrene, and different types of insulation were evaluated for lesser mealworm resistance. In a laboratory study, tetrachlorvinphos and pirimiphos-methyl sprayed on extruded …

Design, Manufacturing, and Control of Soft and Soft/Rigid Hybrid Pneumatic Robotic Systems
… fabric as the primary structural material, but plastic films can be used instead of textiles as well. We introduce two different methods to create layered bellows actuators, which can be made with a heat press machine or in an oven. We also describe origami-like actuators with possible corner …

Nanocomposites: Incorporation of Cellulose Nanocrystals into Polymers and Addition of Zwitterionic Functionality
… rise to properties suitable for applications in plastic films and bags among other end uses. Catalyst 1 functionalized CNCs were added to a reaction vessel with both ethylene and 1-hexene to afford LLDPE CNC composites. Different loading of catalyst 1 on CNC aerogels afforded the same amount of …
