  • Adhesives for biomedical applications can be detached with light December 14, 2018
    Pulling off a little plastic bandage may soon get a lot less painful. Researchers have developed a new type of adhesive that can strongly adhere wet materials -- such as hydrogel and living tissue -- and be easily detached with a specific frequency of light. The adhesives could be used to attach and painlessly detach […]
  • Collagen nanofibrils in mammalian tissues get stronger with exercise December 13, 2018
    A recent experimental study on nanoscale collagen fibrils sheds light on reasons why collagen is such a resilient material.
  • Peeling off slimy biofilms like old stickers December 13, 2018
    Slimy, hard-to-clean bacterial mats called biofilms cause problems ranging from medical infections to clogged drains and fouled industrial equipment. Now, researchers have found a way to cleanly and completely peel off these notorious sludges.
  • Machine learning to speed chemical discoveries, reduce waste December 13, 2018
    Researchers have combined artificial neural networks with infrared thermal imaging to control and interpret chemical reactions with new precision and speed. Novel microreactors allow chemical discoveries to take place quickly and with far less environmental waste than standard large-scale reactions. The system can reduce the decision-making process about certain chemical manufacturing processes from one year […]
  • Crashes increase when speed limits dip far below engineering recommendation December 12, 2018
    Speed limits set only five miles per hour below engineering recommendations produce a statistically significant decrease in total, fatal and injury crashes, and property-damage-only crashes, according to a group of researchers.
  • How plants can generate electricity to power LED light bulbs December 12, 2018
    Researchers have discovered that living plants are literally 'green' power source: they can generate, by a single leaf, more than 150 Volts, enough to simultaneously power 100 LED light bulbs. Researchers also showed that an 'hybrid tree' made of natural and artificial leaves can act as an innovative 'green' electrical generator converting wind into electricity.
  • Chemical engineers develop new theory to build improved nanomaterials December 11, 2018
    Researchers have developed a new theory to better predict how nanoclusters will behave when a given metal is introduced to their structure.
  • Shape-shifting origami could help antenna systems adapt on the fly December 10, 2018
    Researchers have devised a method for using an origami-based structure to create radio frequency filters that have adjustable dimensions, enabling the devices to change which signals they block throughout a large range of frequencies.
  • Antenna evaluation method could help boost 5G network capacity and cut costs December 10, 2018
    Researchers have developed a method for evaluating and selecting optimal antenna designs for future fifth-generation (5G) cellphones, other wireless devices and base stations.
  • Predicting leaky heart valves with 3D printing December 10, 2018
    Researchers have created a novel 3D printing workflow that allows cardiologists to evaluate how different valve sizes will interact with each patient's unique anatomy, before the medical procedure is actually performed. This protocol uses CT scan data to produce physical models of individual patients' aortic valves, in addition to a 'sizer' device to determine the […]
