Before designing the next generation of soft materials, researchers must first understand how they behave during rapidly changing deformation. In a new study, researchers challenged previous assumptions regarding polymer behavior with newly developed laboratory techniques that measure polymer flow at the molecular level.
Before and after comparisons don't tell the full story of chemical reactions in flowing fluids, such as those in drug delivery systems, according to a new study from a collaboration between Tokyo University of Agriculture and Technology (TUAT) and Nihon University based in Japan.
MIT chemical engineers have devised a new way to create nanoemulsions, very tiny droplets of one liquid suspended within another. They also developed a way to easily convert nanoemulsions to a gel when they reach body temperature, which could be useful for developing materials that can deliver medication when rubbed on skin or injected into the body.
With the wearable electronic device market having firmly established itself in the 21st century, active research is being conducted on electronic textiles, which are textiles (e.g. clothing) capable of functioning like electronic devices. Fabric-based items are flexible and can be worn comfortably all day, making them the ideal platform for wearable electronic devices.
Dr. Yu Zhu and his team of graduate students in The University of Akron's College of Polymer Science and Polymer Engineering are working to improve the safety of Li-ion batteries by creating a shear-thickening electrolyte -- a substance that can become thicker under impact, set between the battery's anode and cathode that will be impact-resistant, thus not causing a fire or an explosion upon any collision.
Artificial muscles made from polymers can now be powered by energy from glucose and oxygen, just like biological muscles. This advance may be a step on the way to implantable artificial muscles or autonomous microrobots powered by biomolecules in their surroundings. Researchers at Linköping University, Sweden, have presented their results in the journal Advanced Materials.
A small amount of cheap epoxy resin replaces bulky support materials in making effective carbon capture solid sorbents, developed by scientists at the Energy Safety Research Institute of Swansea University.
Snails can anchor themselves in place using a structure known as an epiphragm. The snail's slimy secretion works its way into the pores found on even seemingly smooth surfaces, then hardens, providing strong adhesion that can be reversed when the slime softens. Penn Engineers have developed a new material that works in a similar way.
Inspired by snail biology, scientists at the University of Pennsylvania, Lehigh University and the Korea Institute of Science and Technology have created a super-glue-like material that is 'intrinsically reversible.' In other words, it can easily come unglued. They have reported their findings in a paper published today in Proceedings of the National Academy of Sciences.
Carbon fiber-enhanced thermoplastic polymer mechanical properties improve when irradiated with an electron beam, report researchers at Kanazawa University in the journal Composites Part A.
