Adhesives for biomedical applications can be detached with light
Fri, 14 Dec 2018 12:18:08 EST
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 wound dressings, transdermal drug delivery devices, and wearable robotics.
Quantum chemical calculations on quantum computers
Fri, 14 Dec 2018 11:08:05 EST
A new quantum algorithm has been implemented for quantum chemical calculations such as Full-CI on quantum computers without exponential/combinatorial explosion, giving exact solutions of Schroedinger Equations for atoms and molecules, for the first time.
Machine learning to speed chemical discoveries, reduce waste
Thu, 13 Dec 2018 14:15:17 EST
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 to a matter of weeks, saving tons of chemical waste and energy in the process.
For a longer battery life: Pushing lithium ion batteries to the next performance level
Thu, 13 Dec 2018 10:13:05 EST
Conventional lithium ion batteries have reached performance limits. Scientists have now developed a new nanostructured anode material for lithium ion batteries, which extends the capacity and cycle life of the batteries. Based on a mesoporous mixed metal oxide in combination with graphene, the material could provide a new approach how to make better use of batteries in large devices such as electric or hybrid vehicles.
DNA study shows stethoscopes loaded with bacteria, including staphylococcus
Wed, 12 Dec 2018 13:50:44 EST
Stethoscopes carried by health care practitioners are loaded with diverse bacteria, including some that can cause healthcare-associated infections, according to a study. The research also reviewed the effectiveness of cleaning methods, finding a standardized approach to be superior for removing bacteria compared with various approaches employed by health care practitioners.
