Alfa Aesar, now part of Thermo Fisher Scientific is a leading manufacturer and supplier of chemicals, metals, and life science products for research and development. For more than 50 years, scientists have relied on Alfa Aesar to supply high purity raw materials for a variety of research and dev more
For over 60 years we have grown crystals and used them to manufacture highly precise optical components for the Infrared, Ultraviolet and Visible regions of the spectrum.For Crystal Growth we are mainly using the Bridman-Stockbarger and Nacken-Kyropoulos techniques-on request we also offer doped cry more
Augsburg Diamond Technology GmbH specializes in the synthesis of large-scale diamond single crystals. The preparation is based on the method of heteroepitaxy, in which diamond is grown in an oriented form on a foreign substrate. The fundamentals of this technology have been developed in the last 20 more
Very narrow gaps make liquids crystallise partially. X-ray investigations at DESY show that in gaps just a few molecule diameters wide both, liquid and crystal properties of a material can exist at the same time. The observation of this coexistence is important for all liquids in very small cavities more
People are not the only ones to be occasionally frustrated. Some crystals also show frustrations. They do so whenever their elementary magnets, the magnetic spins, cannot align properly. Cesium copper chloride (Cs2CuCl4) – or CCC for short – is a prime example of frustrated materials. In this crysta more
Physicists have discovered a new effect, which makes it possible to create excellent thermal insulators which conduct electricity. Such materials can be used to convert waste heat into electrical energy. Every day we lose valuable energy in the form of waste heat - in technical devices at home, but more
How can you determine the structure of a complex molecule from a single crystal? Professor Elspeth Garman take us on a journey into the world of crystallography - from protein production and purification to growing the right type of crystals.In her laboratory at the University of Oxford Elspeth ... more
How do X-rays help us uncover the molecular basis of life?In the second part of this mini-series, Professor Stephen Curry takes us on a journey into the Diamond Light Source, one of the UK's most expensive and sophisticated scientific facilities.Generating light brighter than the sun, and hostin ... more
Researchers slowly pull apart tiny bits of a titanium oxide mineral called rutile. The red dots near the top show the starting point. As the bottom half is pulled down, the top half stays attached by van der Waals forces -- until, that is, the pull becomes too great. The tips are about a thousan ... more
In the Northern Hemisphere at least, the idealised vision of Christmas involves snow. Whilst no one snowflake is exactly the same as another, at least on a molecular level, scientists have none-the-less devised a system of classification for the many types of crystals that snow can form. This graphi more
Kicking off an occasional new series of graphics with today’s post, which’ll be looking at common chemical reactions encountered in schools. Today kicks off with one of my favourite reactions, the ‘Golden Rain’ demonstration, which involves the synthesis and recrystallisation of lead (II) iodide, an more
Homogeneous KSc2F7 microcrystals with controlled and abundant morphologies were prepared by a one-step hydrothermal route without employing any templates or surfactants. Particularly, uniform and well-defined KSc2F7 crystals with rod, sheet, flower-like, thin rectangular, xylitol-like and thin plate more
In this study, we report a deep red emissive organic crystal that displays high contrast fluorescence switching under mechanical- and thermal stimulation. Upon mechanical grinding, the pristine red emissive crystals of 1R (λem = 667 nm) transformed to green emissive crystalline powder (λem = 550 nm) more
Crystalline solid solutions are a long known class of materials that enables the fine tuning of a material structure and properties. Some of them like metal alloys have been employed in everyday life for thousands of years. As result, these phases represent an important part of materials science. On more
Colloidal crystals Definition Colloidal crystals are ordered arrangements of particles between 100nm to 1μm. more
