UW Researchers Measure Dynamics of Microscale Granular Crystals

Materials that react to dynamic loading can provide better protection to military convoys, reduce vibrations in vehicles, and can make buildings relatively safer during earthquakes. [More]

Materials Researchers Develop New Technique to Deposit Diamond on Cubic Boron Nitride Surface

Materials researchers at North Carolina State University have developed a new technique to deposit diamond on the surface of cubic boron nitride (c-BN), integrating the two materials into a single crystalline structure. [More]
Researchers Tune Hardness in Pure Calcite Using Amino Acids

Researchers Tune Hardness in Pure Calcite Using Amino Acids

Pure calcite is a weak, fragile mineral that is generally present in chalk. As such, construction engineers do not prefer to use this mineral as a building material. However, if calcite is reinforced by a factor of two or more, similar to the way a mollusk has done to protect itself from predators through an evolutionary process, it could be a suitable building material.

UC San Diego Chemists Create Adaptive Protein Crystal

UC San Diego Chemists Create Adaptive Protein Crystal

UC San Diego chemists have produced an ‘adaptive protein crystal’ that possesses a unique counterintuitive property, which could be useful in designing body armors and soles of running shoes. When the material is stretched in a single direction, it thickens in the perpendicular direction instead of thinning, as seen in common materials, and when the material is compressed in one dimension, it reduces in the other dimension instead of expanding and becomes thicker during the process.

Researchers Obtain Deeper Insight into Self-Healing Nature of Colloidal Crystals

Researchers Obtain Deeper Insight into Self-Healing Nature of Colloidal Crystals

When an assembly of microgel particles includes one particle that's significantly larger than the rest, that oversized particle spontaneously shrinks to match the size of its smaller neighbors. This self-healing nature of the system allows the microparticles to form defect-free colloidal crystals, an unusual property not seen in systems made up of “hard” particles. [More]

Researchers Provide First Definitive Evidence for Twist-Bend Phase of Liquid Crystals

Discovered more than 125 years ago, liquid crystals play a significant role in screens of computer monitors and TV, watches, clocks and a variety of other electronics displays. Scientists are still attempting to improve the molecular makeup of these liquid crystals. [More]

UCSB Researchers Identify Specific Defects that Hinder LED Performance

UCSB researchers have used modern theoretical methods to detect particular defects that hinder the performance of a light-emitting diode (LED). The characterization of such defects present in the LED’s atomic structure could result in the development of longer lasting and more efficient LED lighting. [More]
Researchers Develop Low-Noise Hybrid Pixel Array Detectors

Researchers Develop Low-Noise Hybrid Pixel Array Detectors

The detector group at the Swiss Light Source at PSI has been one of the pioneers in the development of custom-made hybrid pixel array detectors (HPADs) for synchrotron applications. In a paper published recently [Jungmann-Smith et al. (2016). J. Synchrotron Rad. 23, 385-394; doi:10.1107/S1600577515023541], this group shows that it is now possible to develop HPADs with sufficient low noise to allow single-photon detection below 1 keV as well as to perform spectroscopic imaging. A commentary has also been written about the work [Graafsma (2016). J. Synchrotron Rad. 23, 383-384; doi:10.1107/S1600577516002721]. [More]
