Microplastic pollution in the Northeast Atlantic: First long-term record from deep water layers of the open ocean

The most common plastic materials were polyethylene and PVC

06-Jul-2022

Scientists from the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) for the first time analysed a long-term sample series on microplastic pollution in the Northeast Atlantic from 2000 m water depth with respect to number, size, mass, material and possible origin of the particles. ...

Built to last: New copolymer binder to extend the life of lithium ion batteries

Scientists develop a novel binder material that protects the graphite anode of Li-ion batteries from degradation even after 1700 cycles

09-Mar-2021

Anyone who has owned a smartphone for over a year is most likely aware that its built-in lithium (Li)-ion battery does not hold as much charge as when the device was new. The degradation of Li-ion batteries is a serious issue that greatly limits the useful life of portable electronic devices, ...

Lefty or righty molecules lend a hand to material structures

Effort to build bottom-up chiral polymers with unique functions

14-Feb-2019

As below, so above. That seems to be an operating principle for molecules that start with a basic chirality - or "handed-ness" -- and pass it on as they combine into larger structures. An international team that included Rice University materials scientist Edwin Thomas pried a new, fundamental ...

From wood waste to high-performance polymers

A transparent and thermally stable polyamide – 100 percent biobased

31-Aug-2018

The natural substance 3-carene is a component of turpentine oil, a waste stream of the production of cellulose from wood. Up to now, this by-product has been incinerated for the most part. Fraunhofer researchers are using new catalytic processes to convert 3-carene into building blocks for ...

An Elastic Puff of Air

Superflexible aerogels are highly efficient absorbents, thermal insulators, and pressure sensors

27-Jul-2018

Airy, Airier, Aerogel. Until now, brittleness has limited the practical application of these delicate solids, which consist almost entirely of air-filled pores. This may now change: Japanese researchers have now introduced extremely elastic aerogels that are easy to process and can be produced at ...

Tailored Polymers from a Printer

Efficient chain transfer for 3D-printing of tough photopolymers

10-Jul-2018

An ever-growing number of coatings, including varnishes and printing inks, as well as tooth fillings, are cured with light. Yet, homogenous, tailored, polymer networks cannot be produced, and the materials tend to be brittle, which limits the use of photopolymers in applications like 3D printing, ...

Customizing polymers using visible light

22-Mar-2018

Researchers from Tokyo Metropolitan University used a light-sensitive iridium-palladium catalyst to make "sequential" polymers, using visible light to change how different building blocks are combined into polymer chains. By simply switching the light on or off, they were able to realize ...

Photoreversible molecular switch changes the physical property of thermoresponsive polymer

05-Feb-2018

Researchers have developed a novel strategy to control the shapes of polymeric materials by utilizing photoresponsive molecular switches, which may evolve tractable stimuli-responsive soft materials. Ionic liquids (ILs) are liquid-state salts at room temperature and are high-potential materials ...

Technique enables printable and rewritable color images

03-Aug-2017

A chemical process that allows color images to be printed on specially coated paper and then erased so that different images can be printed on the same paper has been developed by researchers at Rice, Yonsei and Korea universities. The technique makes use of structural colors, which have ...

Polymerisation pilot facilities can accelerate the development of biobased materials

30-Jun-2017

While the polymerisation of biobased monomers is an important step in making plastics, resins and coatings from plant materials which can compete with their fossil counterparts, there are currently no pilot facilities for this process available in the Dutch R&D ecosystem. Industry, regional ...
