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]

First Experimental Observation of Isostructural Solid-Solid Transition at Single-Particle Level

First Experimental Observation of Isostructural Solid-Solid Transition at Single-Particle Level

A solid’s surface usually melts into a thin liquid layer prior to the melting point. This phenomenon of surface melting occurs in all categories of solids: for example, two ice cubes can fuse at a temperature less than 0°C as the premelted surface water is surrounded inside the bulk at the point of contact and is frozen. Premelting promotes crystal growth, and is vital in geology, metallurgy, and meteorology, such as frost heave, snowflake growth, glacier movement, and skating. As there is a lack of microscopic measurements, the causes of several premelting scenarios and the impact of dimensionality on the premelting phenomenon are poorly understood. [More]

New Crystal with Unusual Conducting and Insulating Properties Could Hold Key for Future Electronic Technologies

Researchers at Princeton University have observed a bizarre behavior in a strange new crystal that could hold the key for future electronic technologies. Unlike most materials in which electrons travel on the surface, in these new materials the electrons sink into the depths of the crystal through special conductive channels. [More]
Updated Crystalline Sponge Technique for Single-Crystal X-ray Diffraction Analysis

Updated Crystalline Sponge Technique for Single-Crystal X-ray Diffraction Analysis

X-ray crystallographic analysis is one of the only methods that provides direct information on molecular structures at the atomic level. The method, however, has the intrinsic limitation that the target molecules must be crystalline, and high-quality single crystals must be prepared before measurement. [More]

Scientists Study Magnetic and Ferroelectric Properties of Multiferroic Materials

In 1894, Pierre Curie speculated on the “the symmetry in physical phenomena, symmetry of an electric field and a magnetic field.” Since then material scientists have working to discover a unique material that displays the coexistence of ferroelectricity and magnetism in a single compound, referred to as a multiferroic compound.
