Scientists have produced an oxide glass with unprecedented toughness. Under high pressures and temperatures, they succeeded in paracrystallizing an aluminosilicate glass: The resulting crystal-like structures cause the glass to withstand very high stresses and are retained under ambient conditions.
Paracrystallization thus proves to be a promising process for producing extremely break-resistant glasses.
starts with oxide glasses which have a rather disordered internal structure and are the most widely commercially utilized glass materials. Using aluminosilicate, which contains silicon, aluminum, boron, and oxygen, as an example, the research team in Germany and China has now succeeded in giving it a new structure.

Scientists invent new way to sort cells by type using lightResearchers have developed and demonstrated a new method for high-throughput single-cell sorting that uses stimulated Raman spectroscopy rather than the traditional approach of fluorescence-activated cell sorting. The new approach could offer a label-free, nondestructive way to sort cells for a variety of applications, including microbiology, cancer detection and cell therapy.
