By closing this loophole, the researchers hope to contribute to the development of more efficient solar cells using this iron-based solar cell. http://creativecommons.org/licenses/by-nc-sa/3.0/ New bio-inspired hydrogels can act like superglue in highly ionic environments like seawater https://phys.org/news/2019-11-bio-inspired-hydrogels-superglue-highly-ionic.html https://phys.org/news/2019-11-bio-inspired-hydrogels-superglue-highly-ionic.html Tue, 12 Nov 2019 15:16:24 UTC Chemistry News - Biochemistry, Polymers, Materials Science Scientists have been working on developing adhesives for the marine environment that are inspired by organisms that fix themselves to underwater surfaces, like mussels. These catechol-based glues are easily oxidized and so eventually lose their adhesiveness, making them less than satisfactory for their intended purpose. http://creativecommons.org/licenses/by-nc-sa/3.0/ Mechanisms of soft tissue and protein preservation in Tyrannosaurus rex https://phys.org/news/2019-11-mechanisms-soft-tissue-protein-tyrannosaurus.html https://phys.org/news/2019-11-mechanisms-soft-tissue-protein-tyrannosaurus.html Tue, 12 Nov 2019 14:31:34 UTC Chemistry News - Biochemistry, Polymers, Materials Science The existing notion that soft tissue architectures and native proteins can be preserved across geological time is controversial since methods of such preservation remain to be investigated and well-defined. In a new study, Elizabeth M. Boatman and colleagues at the departments of Engineering, Paleontology, Biological Science, Materials and Engineering and the Advanced Light Source in the U.S., tested crosslinking mechanisms for preserved tissue architecture. They used two non-enzymatic, structural protein mechanisms, Fenton chemistry and glycation to demonstrate their possible contributions to preserve blood vessel structures recovered from the cortical bone of Tyrannosaurus rex (T. rex; USNM 555 000, formerly MOR 555). They demonstrated the endogeneity (randomness) of the fossil vessel tissues and the presence of type I collagen in the outermost vessel layers using imaging, diffraction, spectroscopy and immunohistochemistry. http://creativecommons.org/licenses/by-nc-sa/3.0/ Metal industry is about to undergo one of the greatest upheavals in history, expert says https://phys.org/news/2019-11-metal-industry-greatest-upheavals-history.html https://phys.org/news/2019-11-metal-industry-greatest-upheavals-history.html Tue, 12 Nov 2019 13:50:01 UTC Chemistry News - Biochemistry, Polymers, Materials Science Metallic materials are the backbone of modern economies. However, large quantities of CO2 are produced during their production and processing. The metal industry must therefore use more climate-friendly processes in the future. The CO2 balance of alloys and their components must also be improved over their entire service life. Dierk Raabe, Director at the Max-Planck-Institut f�r Eisenforschung in D�sseldorf, explains the possibilities that industrial companies already have in this respect as well as the tasks that metallurgists must take on in order to achieve the goal of a sustainable metal industry. http://creativecommons.org/licenses/by-nc-sa/3.0/ Researchers strengthen weakest link in manufacturing strong materials https://phys.org/news/2019-11-weakest-link-strong-materials.html https://phys.org/news/2019-11-weakest-link-strong-materials.html Tue, 12 Nov 2019 13:45:25 UTC Chemistry News - Biochemistry, Polymers, Materials Science Industrial and automotive machinery, such as automotive engine parts, contain materials that are, heat-, wear-, and corrosion-resistant. They are known as "super engineering plastics," and they continue to revolutionize manufacturing processes. While they are actually plastic, they are much stronger than the typical plastics we encounter in everyday life. These materials, however, create a corrosive environment during manufacturing. http://creativecommons.org/licenses/by-nc-sa/3.0/ Scientists develop superfast-charging, high-capacity potassium batteries https://phys.org/news/2019-11-scientists-superfast-charging-high-capacity-potassium-batteries.html https://phys.org/news/2019-11-scientists-superfast-charging-high-capacity-potassium-batteries.html Tue, 12 Nov 2019 13:30:02 UTC Chemistry News - Biochemistry, Polymers, Materials Science Skoltech researchers in collaboration with scientists from the Institute for Problems of Chemical Physics of RAS and the Ural Federal University have shown that high-capacity, high-power batteries can be made from organic materials without lithium or other rare elements. In addition, they demonstrated the impressive stability of cathode materials and recorded high energy density in fast charge/discharge potassium-based batteries. The results of their studies were published in the Journal of Materials Chemistry A, the Journal of Physical Chemistry Letters and Chemical Communications. http://creativecommons.org/licenses/by-nc-sa/3.0/ High resolution cryo-EM images from Africa pave the way to bespoke nitrilases for industry https://phys.org/news/2019-11-high-resolution-cryo-em-images-africa.html https://phys.org/news/2019-11-high-resolution-cryo-em-images-africa.html Tue, 12 Nov 2019 13:24:09 UTC Chemistry News - Biochemistry, Polymers, Materials Science A team from Cape Town have recently published the first high-resolution cryo-electron microscopy (EM) paper to originate from Africa. As described in Nature Communications Biology, the team solved the structure of a nitrilases enzyme to a close-to-atomic resolution and used the structural insights to design a mutant enzyme that could be fine-tuned for applications in biotechnology. This work was made possible through an access program funded by the Synchrotron Techniques for African Research and Technology project, a collaborative grant which seeks to build partnerships between world leading scientists in Africa and the UK working together on research using synchrotron science. http://creativecommons.org/licenses/by-nc-sa/3.0/ A fast and precise look into fiber-reinforced composites https://phys.org/news/2019-11-fast-precise-fiber-reinforced-composites.html https://phys.org/news/2019-11-fast-precise-fiber-reinforced-composites.html Tue, 12 Nov 2019 13:15:54 UTC Chemistry News - Biochemistry, Polymers, Materials Science Researchers at the Paul Scherrer Institute PSI have improved a method for small angle X-ray scattering (SAXS) to such an extent that it can now be used in the development or quality control of novel fiber-reinforced composites. This means that in the future, such materials can be investigated not only with X-rays from especially powerful sources such as the Swiss Light Source SLS, but also with those from conventional X-ray tubes. The researchers have published their results in the journal Nature Communications. http://creativecommons.org/licenses/by-nc-sa/3.0/ Cardiac Biomarkers Identify High-Risk Kidney Disease Patients https://www.labmedica.com/clinical-chemistry/articles/294779940/cardiac-biomarkers-identify-high-risk-kidney-disease-patients.html https://www.labmedica.com/clinical-chemistry/articles/294779940/cardiac-biomarkers-identify-high-risk-kidney-disease-patients.html Tue, 12 Nov 2019 06:33:41 UTC Clinical Chemistry | LabMedica International Cardiovascular disease (CVD) claims more lives in people with chronic kidney disease (CKD) than complications of kidney disease and this... http://creativecommons.org/licenses/by-nc-sa/3.0/ Perovskite Quantum Dots Self-Assemble into Nanowires http://www.chemistryviews.org/details/ezine/11196828/Perovskite_Quantum_Dots_Self-Assemble_into_Nanowires.html http://www.chemistryviews.org/details/ezine/11196828/Perovskite_Quantum_Dots_Self-Assemble_into_Nanowires.html Tue, 12 Nov 2019 00:00:00 UTC ChemistryViews.org Magazine Home Surface defects enable ligand-assisted self-assembly http://creativecommons.org/licenses/by-nc-sa/3.0/
