Materials having excess electrons are typically conductors. However, moire patterns -- interference patterns that typically arise when one object with a repetitive pattern is placed over another with a similar pattern -- can suppress electrical conductivity.
Engineers have developed a soft, stretchy skin patch that can be worn on the neck to continuously track blood pressure and heart rate while measuring the wearer?s levels of glucose as well as lactate, alcohol or caffeine.
Nanoscientists develop adaptive microelectronics that can move independently according to sensor data and align themselves specifically for activities - possible applications in biomedicine and bioneural interfacing.
Theoretical calculations predict that the compound known as 'kagome graphene' should have completely different properties to graphene. Kagome graphene consists of a regular pattern of hexagons and equilateral triangles that surround one another.
Using an advanced technique, scientists have demonstrated that a chemical reaction powered by light takes place ten thousand times faster at the air-water interface - what we usually call the water surface - than in the bulk of the water, even when the light has equivalent energy.
Interactions between individual molecules on a metal surface extend for surprisingly large distances - up to several nanometers. A new study of the changing shape of electronic states induced by these interactions, has potential future application in the use of molecules as individually addressable units.
