A team of researchers has reported the first laboratory synthesis and recovery of bulk hexagonal diamond, a crystal form long predicted to be harder than the conventional gems used in cutting tools ...

Imaging-based single-cell physiological profiling holds great potential for uncovering fundamental bacterial cold shock response (CSR) mechanisms, but its application is impeded by severe focus drift ...

Diamonds are famous for their strength, but scientists have long suspected that another form of diamond might be even harder. Evidence of this was gathered over the past sixty years in meteorite ...

Scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a new way to determine atomic structures from nanocrystals previously considered unusable, ...

Quantum physics overturned classical ideas by showing that matter behaves very differently at the smallest scales. One of its most surprising discoveries was wave-particle duality, the idea that ...

Optical dispersion occurs when the refractive index of a material changes with the wavelength of incoming light. This variation causes different colors to move at different speeds in transparent media ...

Abstract: The concept of metagratings has been proposed as an efficient method of controlling the diffraction field of electromagnetic waves. In this paper, a reflective metagrating with ...

Ptychography is an area-by-area scanning method that uses constant, coherent illumination to scan a region of a sample in several adjacent and overlapping locations. The dispersed radiation is ...

Crystallography is the science of analyzing the pattern produced by shining an X-ray beam through a material sample. A powder sample produces a different pattern than solid crystal. One longstanding ...
