Photodegradation of biodegradable plastics in aquatic environments: Current understanding and challenges

Florian Frédéric Vincent Breider, Vinhteang Kaing

Direct photolysis and indirect photolysis are important abiotic processes in aquatic environments through which plastics can be transformed physically and chemically. Transport of biodegradable plastics in water is influenced by vertical mixing and turbule ...

Acetal-Stabilized Carbohydrates as Novel Platform Molecules for Renewable Polymer Production

Lorenz Perry Manker

To address the rising demand for plastics, it is essential to create new types of polymers that are both highly recyclable and emit minimal amounts of greenhouse gases. These plastics should be derived from readily available, renewable feedstocks. Such eff ...

Quantified Effects of Multiple Parameters on Inputs and Potential Sources of Microplastics from a Typical River Flowing into the Sea

Florian Frédéric Vincent Breider, Yang Liu, Wenxin Liu

As an important connection of terrestrial and marine ecosystems, rivers input multitudinous (micro)plastics into the oceans. However, comparisons of field and estimated riverine inputs of (micro)plastics and contributions of multiple parameters are limited ...

Physically Based Modeling of Shear Modulus-Temperature Relationship for Thermosets

Thomas Keller, Anastasios Vassilopoulos, Wei Sun

A new physically based model for the simulation of the imaginary part of the shear modulus-temperature (G ''-T) curve of thermosets is introduced in this paper. The model is based on the modification of the G ''-T equation used for thermoplastic polymers v ...
