I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Researchers discover new photoactivation mechanism for polymer production” Credit: Anh Thy Bui A team of researchers from North Carolina State University has demonstrated a way to use low-energy, visible light to produce polymer gel objects from pure monomer solutions. The work not only poses a potential solution to current challenges in producing these materials, it…
“#Stable supply of electrochromic metallo-supramolecular polymer” Dimming EC glass comprising a metallo-supramolecular polymer. Credit: National Institute for Materials Science National Institute for Materials Science (NIMS) and Tokyo Chemical Industry Co., Ltd. (TCI) have jointly developed a synthetic process capable of stably supplying a metallo-supramolecular polymer electrochromic (EC) material. Popularization of this material may stimulate growth…
“#Nanomaterials— short polymers, big impact” Researchers used computer simulations to produce images of polymer nanocomposite materials. Nanoparticles are shown in pink and long polymer chains in cyan. Credit: Jan-Michael Y. Carrillo/ORNL, U.S. Dept. of Energy Oak Ridge National Laboratory scientists have discovered a cost-effective way to significantly improve the mechanical performance of common polymer nanocomposite…
“#Polymers prevent potentially hazardous mist during dentist visit” Using polyacrylic acid solution in water as irrigation fluid in dentistry reduces risk of aerosolized pathogens. Here, the polymer is shown forming snakelike threads near the tip of a vibrating cavitron scaler (top), and it forms spools near the tip of a turbine-driven dental drill. In both…
“#A way to intentionally change the curvature of bent molecules using a polymer and ultraviolet light” Scanning electron microscopy image of the colloidal bananas. Note the false coloring emphasizes the shape of the particles. The scale bar is 5 micrometers. Credit: Carla Fernandez-Rico A team of researchers from the University of Oxford and Utrecht University…
“#A new kind of plastic that is able to maintain its original qualities when recycled” Determination of topology by MALDI-TOF MS and viscosity. (A) MS spectrum and plot of mass/charge ratio (m/z) values versus the theoretical number of M repeat units for the linear PBTL produced by IMes and BnOH. (B) MS spectrum and plot…
“#Small enzyme-mimicking polymers may have helped start life” The micrograph shows uniform nanoparticles under 10nm in diameter. Credit: Tony Z. Jia, ELSI Most effort in origins of life research is focused on understanding the prebiotic formation of biological building blocks. However, it is possible early biological evolution relied on different chemical structures and processes, and…
“#’Cyborg’ technology could enable new diagnostics, merger of humans and AI” Molecular model of PEDOT with maleimide; carbon atoms are grey, oxygens red, nitrogens blue, sulfurs yellow and hydrogens white. Credit: David Martin Although true “cyborgs”—part human, part robotic beings—are science fiction, researchers are taking steps toward integrating electronics with the body. Such devices could…
“#Metal organic frameworks made to act as liquids” One challenge for the team was to make a crystalline MOF behave as a porous liquid. The team discovered how to modify the surface of relatively large MOF nanoparticles with suitable chemical groups. This “surface functionalization” allowed the nanoparticles to form stable dispersions in a liquid solvent….
“#Analyzing pros and cons of two composite manufacturing methods” Credit: Pixabay/CC0 Public Domain Airplane wings, wind turbine blades, and other large parts are typically created using bulk polymerization in composite manufacturing facilities. They are heated and cured in enormous autoclaves and heated molds as big as the finished part. Frontal polymerization is a new out-of-autoclave…
