Lab reactor, liquefied catalyst, and machine learning for more efficient polymerization design
The synthesis of plastic precursors, such as polymers, involves specialized catalysts. However, the traditional batch-based method of finding and screening the right ones for a given result consumes liters of solvent, generates large quantities of chemical waste, and is an expensive, ...
Chinese researchers under the direction of Profs. LI Xianfeng and ZHANG Huamin from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences recently developed an ultrathin ion-conducting membrane with high selectivity and conductivity that can boost the power of flow ...
Chemical catalysis for an existing class of biomaterials
A tide of public momentum is swelling against the crisis of petroleum-based plastics, which are sitting in our landfills, floating in our oceans, and showing up in our air and even our food. Meanwhile, in a Colorado State University chemistry laboratory, polymer scientists are toiling toward what ...
A Dream Finally Comes True
Scientists at the Center for Advancing Electronics Dresden (cfaed) at TU Dresden have succeeded in synthesizing sheet-like 2D polymers by a bottom-up process for the first time. A novel synthetic reaction route was developed for this purpose. The 2D polymers consist of only a few single atomic ...
In the FOWINA project, the Fraunhofer Institute for Integrated Circuits IIS in Erlangen and the Fraunhofer Institute for Silicate Research ISC in Würzburg have developed novel color sensors with a special microlens arrangement. The sensors can be realized directly on the chip and combine multiple ...
Recipes for three-dimensional (3D) printing, or additive manufacturing, of parts have required as much guesswork as science. Until now. Resins and other materials that react under light to form polymers, or long chains of molecules, are attractive for 3D printing of parts ranging from ...
Efficient chain transfer for 3D-printing of tough photopolymers
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, ...
Properties of recyclable plastics can be defined by the wavelength
A research team from Berlin has developed a novel catalyst system, which enables the regulation of multiple polymerization processes to produce biodegradable plastics solely by illumination with light of different colors. The properties of a polymeric material are highly dependent on factors, ...
There's a good chance you've touched something made out of the polyolefin polymer today. It's often used in polyethylene products like plastic bags or polypropylene products like diapers. As useful as polyolefins are in society, they continue to multiply as trash in the environment. Scientists ...
The interactions of biological macromolecules such as nucleic acids, proteins, and polysaccharide–protein conjugates can be mimicked by artificial polyelectrolytes. Such synthetic polyionic complexes are expected to serve as novel platforms to stabilize and deliver drugs, proteins, or nucleic ...
