The AFM “sees” the sample surface with a special part known as the AFM tip. The AFM tip is brought close to the sample surface until it is, for most intents and purposes, touching the sample surface. Then, the AFM tip is scanned over the sample surface to produce a...

A group of researchers from China, led by Professor Han Zhang from Shenzhen University, Professor Xue-Feng Yu from the Chinese Academy of Science, and Professor Lei Liao from Wuhan University, reported a breakthrough in metal-ion-modified black phosphorus with...

A group of scientists at #Nagoya University have developed a simple and powerful method to construct perfectly unidirectional molecular assembly structures on graphene. Interestingly, the method was discovered accidentally during other research. In order to apply the...

Atomic force microscopy (AFM) was conducted to examine the surface structure of the prepared PVA films. Fascinatingly, the new micro-level developed surface, twisted by electro-spraying is very promising for humidity sensors. The resistivity of the humidity sensors...

Piezoelectricity is the conversion of mechanical energy into electricity which was discovered by Jacques and Pierre Curie in 1880. The principle of piezoelectricity nowadays is commonly applied in things such as voice recognition software, microphones, and etc....
