  • Insight into a hidden order

    A specific uranium compound has puzzled researchers for thirty years. Although the crystal structure is simple, no one understands exactly what is happening once it is cooled below a certain temperature. Apparently, a “hidden order” emerges,  whose nature is completely unknown.Now physicists have ch more

  • A little tension yields enormous solar crystals

    In the race to replace silicon in low-cost solar cells, semiconductors known as metal halide perovskites are favored because they can be solution-processed into thin films with excellent photovoltaic efficiency. A collaboration between KAUST and Oxford University researchers has now uncovered a stra more

  • Study pinpoints role of proteins that produce pearls

    Pearls are among nature's most beautiful creations, and have been treasured for countless centuries. Beneath one's iridescent surface lies a tough and resilient structure made of intricately arranged tiles of calcium carbonate organized by a crew of proteins that guide its formation and repair. Whil more

Understanding Crystallography - Part 1: From Proteins to Crystals

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

Understanding Crystallography - Part 2: From Crystals to Diamond

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

Pulling Apart Titanium Oxide Surfaces

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

The Shapes of Snowflakes

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

Lead Iodide & ‘Golden Rain’

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

Batch Crystallization Control

Batch cooling crystallization is widely applied to isolate high-purity chemicals and pharmaceuticals. Control over the size of crystals produced by such operations can be critical for efficient downstream operations. Daniel Griffin of Amgen describes a new model-based, closed-loop approach for contr
