Conversion of plastic wastes to fatty acids is an attractive means supplement the sourcing these high-value, high-volume chemicals. We report a method for transforming polyethylene (PE) and polypropylene (PP) at ~80% conversion with number-average molar masses up ~700 670 daltons, respectively. The process applicable municipal PE PP their mixtures. Temperature-gradient thermolysis key controllably degrading into waxes inhibiting production small molecules. are upcycled by oxidation over manganese stearate subsequent processing. ꞵ-scission produces more olefin wax yields higher acid-number than does ꞵ-scission. further convert large-market-volume surfactants. Industrial-scale technoeconomic analysis suggests economic viability without need subsidies.

A state-of-the-art review focusing on the significant techniques for naturally available fibers as reinforcement in sustainable bio-composites: Extraction, processing, purification, modification, as well as characterization study

Results in Engineering, Journal Year: 2023, Volume and Issue: 20, P. 101511 - 101511

Published: Oct. 18, 2023

Eco-friendly bio-active materials designed from available natural resources have been signified a big challenge in the past few decades. Nevertheless, deficiency of most essential knowledge regarding effective processing starting which has used to fabricate targeted bio-polymeric composites framework is considered foremost encounter. However, cellulosic fibers (generally extracted different parts plants like bast/bark, leaf, steam) received more attention researchers, due their outstanding physiochemical, thermomechanical, morphological properties and eco-friendly nature/sustainability. Basically, features hinge on proper preparation modification process. Conversely, main problem fiber its hydrophilic nature while polymeric matrix are hydrophobic thus it urgent reduce by conducting various significant chemical techniques so as improve overall quality reinforcement sustainable biocomposite. Therefore, will be proposed with detailed overview focusing notable process modifications characterization methods this review. We also summarize important findings earlier literature effects treatments being emphasized.

Review and Perspectives of sustainable, biodegradable, eco-friendly and flexible electronic devices and (Bio)sensors

Biosensors and Bioelectronics X, Journal Year: 2023, Volume and Issue: 14, P. 100371 - 100371

Published: June 16, 2023

The demand for increasingly advanced bioelectronic devices with smart functions, long-term stability, and the ability to operate outdoors extended periods of time has been growing rapidly in modern society. In addition, excellent flexibility, biocompatibility, lightweight design, sustainability, biodegradability environmental friendliness are equally important considerations when choosing mobile electronics. To meet these requirements, flexible need be equipped efficient portable tasks. However, most currently manufactured using plastic substrates/supports, which is not environmentally sustainable. This review focused on research attempts shift biodegradable polymeric materials toward sustainable components. We present recent scientific achievements strategies obtain eco-friendly polymers substrates/support fabrication devices. summarize introduction techniques as components provide substrates/support. Lastly, we summarized few applications reported films commented challenges future prospects unexplored sensing biosensing.
