RADIATION SHIELD, POLYMER MAY REPLACE LEAD
13 مه 2020

PolymPart: The bismuth trioxide compound is lightweight, effective at shielding against ionizing radiation such as gamma rays, and can be manufactured quickly. Those qualities make it a promising material for use in applications such as space exploration, medical imaging, and radiation therapy. “Traditional radiation shielding materials, like lead, are often expensive, heavy, and toxic to […]

Machine Learning Helps Discover New Polymers Which Can Be Used For 5G Connectivity
29 جولای 2019

Over the last few years, the chances of creating new conducting polymers with the help of machine learning have caught the attention of many researchers in the field of chemistry. Now, a team of researchers has discovered a new kind of polymer which contains high thermal conductivity and can be beneficial to the 5G mobile communication technologies. […]

new polymer tackles PFAS pollution
06 ژوئن 2019

PolymPart: A new low-cost, safe and environmentally friendly polymer presents global solution for cleaning up toxic polyfluorinated alkyl substances (PFAS) pollution. The problem of cleaning up toxic polyfluorinated alkyl substances (PFAS) pollution – commonly used in non-stick and protective coatings, lubricants and aviation fire-fighting foams – has been solved through the discovery of a new […]

A high-spin ground-state donor-acceptor conjugated polymer
26 مه 2019

PolymPart: Interest in high-spin organic materials is driven by opportunities to enable far-reaching fundamental science and develop technologies that integrate light element spin, magnetic, and quantum functionalities. Although extensively studied, the intrinsic instability of these materials complicates synthesis and precludes an understanding of how fundamental properties associated with the nature of the chemical bond and […]

Polymer, Not Metal Or Glass Could Be The Future Of Smartphone Material
07 مه 2019

MIT researchers have come up with a potential dealbreaker that could solve heating issues on flagship, gaming and high-powered phones. Forget glass, metal or plastic- the newer mobile phone material may be made of custom polymer. This polymer can solve heating problems inherent with smartphones by allowing dissipation instead of containment. With this mechanism, future […]

Polymer reversibly glows white when stretched
25 آوریل 2019

Researchers at the University of Fribourg’s Adolphe Merkle Institute (AMI) and Hokkaido University in Japan have developed a method to tailor the properties of stress-indicating molecules that can be integrated into polymers and signal damages or excessive mechanical loads with an optical signal. As part of their research activities within the National Center of Competence […]

Polymer dots image deep into the brain
24 مارس 2019

Multiphoton fluorescence microscopy, in which a fluorophore absorbs more than one photon and emits light at a shorter wavelength than the excitation source, can be used to create 3D tissue images at depths of 1 mm or more. Recently, studies have shown that in vivo two- and three-photon microscopy can image neurons and vascular structures […]

Polymer power potential
05 فوریه 2019

The mantra ‘reduce, reuse, recycle’ is increasingly pertinent. Every year, vast amounts of energy that could be captured and reused are lost through waste heat. Now, A*STAR scientists have demonstrated, through theoretical calculations, that it may be possible to fabricate thermoelectric organic polymers that can convert heat into electrical energy with high efficiency. Thermoelectric (TE) […]

Conductive polymer sheet could shrink car and grid storage batteries
31 ژانویه 2019

PolymPart: Researchers at Fraunhofer Umsicht (Fraunhofer institute for environmental, safety and energy technology) have developed a ‘bipolar plate’ (explained below) for bipolar construction batteries (ditto) that is flexible and can be made on a roll-to-roll process. “We manufacture bipolar plates from polymers that have been made electrically conductive,” said Fraunhofer researcher Dr Anna Grevé. “In this way, […]

Using an X-Ray Diffractometer to Determine the Crystallinity in Polymer Samples
22 دسامبر 2018

PolymPart: Polymer materials are utilized for a diverse number of modern societal processes, ranging from packaging to aerospace engineering. Naturally, different types of processes necessitate different material characteristics, which are conditioned by the structural properties of the polymer product. Important observables for polymer materials range from the category of polymer (e.g., Polyethylene PE or Polypropylene […]
