Determining whether the metals components are clean or are adequately lubricated with oil is often important in a manufacturing process. Infrared analysis of tiny, flat pieces can be readily performed ...

Figure 1: Colloidal crystals on curved oil–glycerol interfaces. The topology of surfaces 21 places a constraint on the total defect charge—for example the net charge on a sphere must be 4π, as ...

Inefficient fluid machinery used in the energy and transportation sector are responsible for greenhouse gas emissions and the resulting global warming. To improve efficiency, it is necessary to ...

The impact of liquid drops on solid surfaces is ubiquitous in nature, and of practical importance in many industrial processes. A drop hitting a flat surface retains a circular symmetry throughout the ...

A project at NIST has developed a new way to monitor and assess 3D printing of metals. Finding and correcting defects inadvertently created inside a 3D printed part is one of the biggest challenges ...

The twisted spirals made in this work exhibit interesting, tuneable superconductive properties. Courtesy: S Jin Researchers have found a way to grow layers of two-dimensional (2D) materials with ...
