Sharpening the X-ray view of the nanocosm

A novel lens offers scientists the sharpest X-ray images yet from the nano world. The device is made from alternating layers of tungsten carbide and silicon carbide and can focus hard X-rays into a spot of less than ten nanometers ...

Noninvasive skull optical clearing window for cortical imaging

Researchers have demonstrated a noninvasive approach for creating an optical window in the skulls of mice to image their brains. Prof. Dan Zhu and coworkers from Huazhong University of Science and Technology, China, tested ...

New optical size spectrometer for probing atmospheric particulates

The global environment is suffering from air pollution due to excess particulate matters, resulting in huge societal and economic costs. Air quality is usually characterized by the mass concentration of fine particulate matters ...

Giant intrinsic chirality from planar dielectric nanostructures

Harvard researchers have developed a metasurface comprising a single planar layer of nanostructures exhibiting strong optical chirality in transmission. This means it can let circularly polarized light of one polarization ...

UV laser photolyses to enhance diamond growth

Energy influences the rates of chemical reactions dramatically. Simply heating a gas-phase reaction system deposits energy indiscriminately in internal and translational motions of precursor and intermediate molecules.

Novel lenses enable X-ray microscopy with record resolution

Scientists at DESY have developed novel lenses that enable X-ray microscopy with record resolution in the nanometre regime. Using new materials, the research team led by DESY scientist Sasa Bajt from the Center for Free-Electron ...

Ultrasound imaging needle to transform heart surgery

Heart tissue can be imaged in real-time during keyhole procedures using a new optical ultrasound needle developed by researchers at UCL and Queen Mary University of London (QMUL).

Researchers tunnel to a new light source

With concerns over moving to a clean energy platform worldwide with electric vehicles and renewables, wasted energy is a factor as important as the amount of green energy produced. Thus, solid-state lighting based upon light-emitting ...

Micro-spectroscopy opens new routes for diagnostics

Just as mechanical properties and chemical compositions of materials are of fundamental importance in buildings, the cells that comprise every living organism have different properties and shapes depending on their function ...
