Wearable healthcare devices, such as glucose monitors and heart monitors, are popular due to their ability to gather real-time data that supports users’ health and safety. Despite their benefits, these devices must often be worn on the arms or chest for a long period of time. They can irritate the skin, cause allergic reactions, and […]
Zaps of static electricity might be a wintertime annoyance, but to certain scientists, they represent an untapped source of energy. Using a device called a triboelectric nanogenerator (TENG), mechanical energy can be converted into electrical energy using triboelectric effect static. Many TENGs contain expensive, specially fabricated materials, but one team has instead used inexpensive store-bought […]
Polymers derived from alpha-lipoic acid (αLA), a small molecule that aids in cell metabolism, have the potential to provide versatile and environmentally friendly adhesives, but their instability has long been a barrier to their use in practical settings. Now, engineers at UC Berkeley have discovered a new chemical strategy that overcomes this impediment, opening the […]
Folding cartons are considered sustainable packaging solutions for numerous everyday products – whether breakfast cereals, electronic goods, medicines, or perfume. Made of paper and cardboard, folding boxes save resources when produced and are biodegradable and easy to recycle. However, there remain challenges in producing environmentally friendly adhesives. Researchers at the Fraunhofer Institute for Applied Polymer […]
The search for stronger, more adaptable adhesives is ongoing. According to recent research, that search may come down to adding a dash of salt to two special polymer ingredients known as polyzwitterions, or PZIs. New research from a Florida A&M University-Florida State University (FAMU-FSU) College of Engineering team led by Hoyong Chung, an associate professor […]
Two researchers at the University of Pittsburgh are using their expertise in hydrogels and liquid crystal elastomers – as well as inspiration from Mother Nature – to design a more effective and powerful adhesive for gluing structures underwater. The proposal for META GLUE – Molecularly Engineered Toughness to Augment Grip Likelihood in Underwater Environments – […]
Traditional medical adhesives used in surgical applications often have limited bio-absorbability, high toxicity, and a lack of customizability, leading to suboptimal surgical outcomes. Recent advances in synthetic biology offer an alternative — tailored biocompatible and biodegradable adhesives designed for specific internal biomedical applications, such as in tissue repair and for surgical glues. Researchers working with […]
