The performance, reliability and longevity of machined parts often depend on the physical characteristics of their functional surfaces. However, legacy surface roughness parameters, such as R a, are ...

Lithium-ion batteries charge and discharge because their lithium ions can move in both directions between positive and negative electrodes. Lithium-ion batteries have generally been used in a compact ...

There are numerous analytical methods for establishing the surface roughness as well as the visualization of surface texture. Each of these methods has its own advantages and disadvantages. The ...

Input and modulation of many different parameters are essential for other competitive ‘single measurement mode’ methods to produce better results on various surface textures in the same field of view ...

Wetting is an everyday phenomenon that represents how well liquid spreads on a surface. When water comes into contact with an extremely water-repellent, or ‘superhydrophobic’ surface, droplets bead up ...

Scanning tunnelling microscopes (STMs) have been used for nearly three decades to study the surfaces of metals and semiconductors. But now physicists in Germany have discovered that the instruments ...

Electrical engineers have long been toying with the idea of designing biological molecules that can be directly integrated into electronic circuits. Researchers have developed a way to form these ...

A University of Texas at Dallas graduate student, his advisor and industry collaborators believe they have addressed a long-standing problem troubling scientists and engineers for more than 35 years: ...

A few months ago, I've written about the most powerful microscope in the world which was able to display images at an incredible high-resolution of just 0.05 nanometer (or 50 picometers). It seems ...

Today, a vast number of micro-manufactured sensors, actuators and components vibrate at frequencies in the high MHz range. Some examples of these high-frequency vibrating systems include surface ...
