A light-programmable, dynamic ultrasound wavefront

The notion of a phased array was initially articulated by Nobel Prize recipient K. F. Braun. Phased arrays have subsequently evolved into a formidable mechanism for wave manipulation. This assertion holds particularly true ...

Polaritons enable tunable and efficient molecular charge transfer across broader spectrum of light

Polaritons are quasiparticles emerging from strong interactions between light particles (i.e., photons) and matter excitations (e.g., excitons). Over the past few years, researchers have found that these quasiparticles can ...

X-ray flashes reveal how electron-hole pairs tug at atoms inside quantum dots

When light hits solar cells, so-called electron-hole pairs are created: the electrons are excited and can move almost freely in the material—i.e. to generate electricity. The electrons will leave 'positive gaps," so-called ...

New co-assembly strategy unlocks robust circularly polarized luminescence across the color spectrum

Researchers at the College of Design and Engineering (CDE) at the National University of Singapore (NUS) have developed a supramolecular co-assembly platform that produces chiral soft materials with strong and stable full-color ...
