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
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
We are innovating ATR infrared spectroscopy by making it easier, cheaper and better. Boost the performance of your ATR device with our crystals and accessories.We developed a procedure to manufacture cost-effective and high-quality ATR crystals. Our products are made of silicon, can be functionalize more
Researchers from the University of Rostock and Technion Haifa have created the first three-dimensional topological insulator for light. A judiciously placed screw dislocation allows optical signals to wind around the surface of a synthetic lattice while keeping it protected from scattering. Their di more
CO2 and methane can be turned into valuable products. But until now the catalysts required for such reactions quickly lose their effectiveness. TU Wien has now developed more stable alternatives. Wherever the production of harmful greenhouse gases cannot be prevented, they should be converted into s more
Scientists have connected two soft crystals and observed energy transfer between them—a finding that could lead to the development of sophisticated, responsive materials. The study, by scientists at Hokkaido University in Japan, was published in the journal Nature Communications. Soft crystals are f 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
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
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
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
