Pathways to Aromatics in the Catalytic Pyrolysis of a Polyvinylchloride Model Compound Revealed by Operando Photoelectron Photoion Coincidence Spectroscopy

ChemSusChem, EarlyView.
How are aromatics formed during catalytic PVC pyrolysis? By utilizing photoelectron photoion coincidence spectroscopy, the cross‐linking reaction mechanism is unveiled to proceed via butadiene dimerization and trimerization, yielding 5‐ or 6‐membered ring species, which are the precursors for benzene, toluene, and xylenes.

Microplastic in Drinking Water: A Pilot Study

Microplastics
In recent years, microplastic pollution has been a hot topic as these compounds have been used in various production contexts such as health, food or technology due to their chemical and physical properties and “shelf-life,” making them almost ...

GANsemble for Small and Imbalanced Data Sets: A Baseline for Synthetic Microplastics Data [PDF]

arXiv
Microplastic particle ingestion or inhalation by humans is a problem of growing concern. Unfortunately, current research methods that use machine learning to understand their potential harms are obstructed by a lack of available data. Deep learning techniques in particular are challenged by such domains where only small or imbalanced data sets are ...

Generating Solar Steam Using Waste Cellulose Fabric: Harnessing Synthetic Yet Plentiful and Cost‐Effective Resources

ChemSusChem, EarlyView.
This study develops solar steam generators using waste fabric. Cotton fabric heat‐treated at 400 °C for 1 h exhibits 94.7% light absorbance and an evaporation rate of 2.66 kg (m−2 h−1). The method leverages artificial 3D structures to provide a cost‐effective and sustainable solution for steam generation.

Uptake and Cellular Effects of Polymethylmethacrylate on Human Cell Lines

Microplastics
The usage of plastic and its decomposition products leads to their ubiquitous distribution, resulting in their uptake by all living beings, including humans. Polymethylmethacrylate (PMMA) is known as a biocompatible polymer and is used widely in medicine

Plastic‐to‐Treasure: Innovative advances in photo/electro‐catalytic upcycling technologies for commodity chemicals and fuels

EcoEnergy, EarlyView.
A huge amount of plastic waste is generated yearly. With the aid of photo/electrocatalysis, they can be upcycled to clean fuels and green chemicals, leading to rehabilitation of the environment and sustainability. This review shines a light on the design of photo/electrocatalysts for effective plastic transformation into economically high‐valued ...

Short-Term Microplastics Exposure to the Common Mysid Shrimp, Americamysis bahia: Effects on Mortality and DNA Methylation

Microplastics
Primary consumers of microplastics are often zooplankton species such as the mysid shrimp, Americamysis bahia. Ingesting and interacting with these plastics can cause stress and lead to death.

Statistical Analysis and Stochastic Dislocation-Based Modelling of Microplasticity [PDF]

arXiv, 2015
Plastic deformation in microscale differs from the macroscopic plasticity in two respects: (i) the flow stress of small samples depends on their size (ii) the scatter of plasticity increases significantly. In this work we focus on the scatter of plasticity.
