Increased electromechanical sensitivity of polysiloxane elastomers by chemical modification with thioacetic groups
Chemically cross-linked polydimethylsiloxane (PDMS) elastomers have gained importance as a dielectric in elastic capacitor actuators, which elongate when electrically charged. Common PDMS elastomers have a dielectric permittivity of only about 3 and thus e ...
2020Evaluation of materials for iodine and technetium immobilization through sorption and redox-driven processes
Wendy Lee Queen, Daniel Teav Sun
Radioactive iodine-129 (I-129) and technetium-99 (Tc-9(9)) pose a risk to groundwater due to their long half-lives, toxicity, and high environmental mobility. Based on literature reviewed in Moore et al. (2019) and Pearce et aL (2019), natural and engineer ...
ELSEVIER2020Reversibly Cross-Linking Polymer Brushes Using Interchain Disulfide Bonds
The introduction of interchain cross-links in surface-grafted polymer brushes increases the robustness and mechanical properties of these thin polymer films. In most cases, cross-linked polymer brushes contain permanent interchain cross-links. The use of r ...
AMER CHEMICAL SOC2020Metal-organic frameworks as kinetic modulators for branched selectivity in hydroformylation
Berend Smit, Gerald Bauer, Daniele Ongari, Davide Tiana, Mohamed Tarik
Finding heterogeneous catalysts that are superior to homogeneous ones for selective catalytic transformations is a major challenge in catalysis. Here, we show how micropores in metal-organic frameworks (MOFs) push homogeneous catalytic reactions into kinet ...
2020Quantification and characterization of microplastics input from runoff water in Kamo and Takano Rivers, Kyoto, Japan.
Microplastic particles can be found everywhere in the world and sources, transport processes and impact on the environment and human health is yet to be well understood. The goal of this work is to quantify and characterize the impact of non-point source m ...
2020Cross-linkable polymer, hydrogel, and method of preparation thereof
Dominique Pioletti, Pierre-Etienne Bourban, Christophe Moser, Peyman Karami, Céline Samira Wyss
The invention relates to a cross-linkable polymer comprising a base polymer comprising functional groups at least some of which have been reacted with a first organic molecule comprising a cross-linkable unit and with a second organic molecule capable of b ...
2020Swelling-Induced Chain Stretching Enhances Hydrolytic Degrafting of Hydrophobic Polymer Brushes in Organic Media
Hydrophilic polymer brushes grown via surface‐initiated polymerization from silicon oxide surfaces can detach or degraft in aqueous media. Degrafting of these chain end‐tethered polymers is believed to involve hydrolysis of bonds at the polymer–substrate i ...
2019Synthesis of Loop Poly(Methyl Methacrylate) Brushes via Chain-End Postpolymerization Modification
Polymer brushes are typically densely grafted assemblies of polymer chains that are tethered via one end group to a solid substrate. Anchoring linear polymer chains via both end groups to a surface results in loop-type polymer brushes. Although loop polyme ...
