MIT researchers have designed a polymer material that can change its structure in response to light, converting from a rigid substance to a softer one that can heal itself when damaged.
Twenty-five researchers from seven research institutes have put their heads together to draw up rules for designing high-efficiency organic solar cells. The research is led by Feng Gao, associate professor at Linkoping University, Sweden.
An international team of researchers, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has discovered that folding is an efficient strategy to incorporate large-area monolayer graphene films on polymer composites and that doing so improves mechanical reinforcement. Their work has been published in the prestigious journal, Advances Materials.
Kyoto University researchers have developed a new approach to control the fabrication of soft, porous materials, overcoming a primary challenge in materials science.
The survival mechanisms of polar fish have led scientists at the University of Warwick to develop of a revolutionary approach to 'freeze' bacteria.
A team of researchers at CNRS, Aix-Marseille Université and Université Paris 13 has demonstrated effective molecular labelling to unequivocally identify biomedical implants, even after a prolonged period inside the living being. These results were published in Angewandte Chemie International Edition on July 5, 2018.
Tetrapeptide Pro-Ala-Gly-Tyr (PAGY) and its analogues, namely, Pro-Ser-Gly-Tyr (PSGY), Pro-Ala-Phe-Tyr (PAFY), Pro-Phe-Phe-Tyr (PFFY) and Pro-Ala-Ile-Tyr (PAIY), were successfully synthesized via a solid phase peptide synthesis method with the Fmoc/t-Bu strategy.
Scientists at the University of Illinois at Urbana-Champaign have predicted new physics governing compression of water under a high-gradient electric field. Physics Professor Aleksei Aksimentiev and his post doctoral researcher James Wilson found that a high electric field applied to a tiny hole in a graphene membrane would compress the water molecules travelling through the pore by 3 percent. The predicted water compression may eventually prove useful in high-precision filtering of biomolecules for biomedical research.

The polymers that make up synthetic materials need time to de-stress after processing, researchers said. A new study has found that entangled, long-chain polymers in solutions relax at two different rates, marking an advancement in fundamental polymer physics. The findings will provide a better understanding of the physical properties of polymeric materials and critical new insight to how individual polymer molecules respond to high-stress processing conditions.
