A new method in electron microscopy enables sub-20-picometer targeting of individual atoms without prior exposure, opening ...

A 3-octave spectral comb is generated in a hydrogen-filled hollow-core photonic-crystal-fiber. The spectrum consists of up to 45 high-order Stokes and anti-Stokes lines generated by coherent ...

A team of researchers has developed a novel method for using cholesteric liquid crystals in optical microcavities. The ...

Lead-halide perovskite nanocrystals (NCs) are promising for fabricating deep-blue (<460 nm) light-emitting diodes (LEDs), but their development is plagued by low electroluminescent performance and ...

A hidden box-lattice suggests groundwater sculpted Mars long after surface water fled; Curiosity’s drills aim to confirm the ...

Requiring catalysts to be both active yet stable over long periods of time under variable reaction conditions including high and low temperatures is a daunting challenge due to the almost mutual ...
