The team of chemists and composite materials researchers discovered a broadly applicable method of bonding plastics and synthetic fibers at the molecular level in a procedure called cross-linking. The cross-linking takes effect when the adhesive is exposed to heat or long-wave UV light making strong connections that are both impact-resistant and corrosion-resistant. Even with a minimal amount of cross-linking, the materials are tightly bonded.
“It turns out the adhesive is particularly effective in high-density polyethylene, which is an important plastic used in bottles, piping, geomembranes, plastic lumber, and many other applications,” says Professor Abbas Milani, director of UBC’s Materials and Manufacturing Research Institute, and the lead researcher at the Okanagan node of the Composite Research Network. “In fact, commercially available glues didn’t work at all on these materials, making our discovery an impressive foundation for a wide range of important uses.”
UVic Organic Chemistry Professor Jeremy Wulff, whose team led the design of the new class of cross-linking materials, collaborated with the UBC Survive and Thrive Applied Research to explore how it performed in real-world applications.
Harder than a diamond, stronger than steel, as flexible as rubber and lighter than aluminum. These are just some of the properties attributed to graphene. Although this material has sparked great interest in the scientific community in recent years, there is still no cheap and sustainable enough method for its high-quality manufacturing on an industrial scale.
After thousands of years as a highly valuable commodity, silk continues to surprise. Now it may help usher in a whole new direction for microelectronics and computing.
While silk protein has been deployed in designer electronics, its use is currently limited in part because silk fibers are a messy tangle of spaghetti-like strands.
Imagine being able to see electrons — the tiny particles that buzz around atoms — in action, darting and swirling in their frenetic dance. This isn’t science fiction anymore.
Scientists have recently developed a state-of-the-art microscope that allows us to observe these elusive particles moving at unimaginable speeds, revealing the intricate behaviors and interactions that occur at the atomic level.
This innovative technology opens up new frontiers for research in physics and materials science, providing unprecedented insights into the fundamental building blocks of matter.
A novel type of superconductor that can operate at elevated temperatures has been found by scientists after nearly three decades of research.
The monolithic 3D integration of 2D molybdenum disulfide memtransistors and graphene chemitransistors can be used to create near-sensor computing chips with high interconnect density and a vertical separation between tiers of less than 50 nm.
Bioactive glasses, a filling material which can bond to tissue and improve the strength of bones and teeth, has been combined with gallium to create a potential treatment for bone cancer.
Tests in labs have found that bioactive glasses doped with the metal have a 99 percent success rate of eliminating cancerous cells and can even regenerate diseased bones.
The research was conducted by a team of Aston University scientists led by Professor Richard Martin who is based in its College of Engineering and Physical Sciences.
Physicists showed that photons can seem to exit a material before entering it, revealing observational evidence of negative time.
