In a lab at Osaka University, physicist Yoshiki Nakata and his colleagues fired a pulsed laser through a stack of three ...

Water molecules replace mechanical force to exfoliate defect-free MXene nanosheets at kilogram scale, enabling record ...

Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase ...

New types of semiconductor devices that respond to light could be possible using materials called perovskites, according to a ...

Heterogeneous catalysis—in which catalysts and reactants are of different phases, e.g., solid and gas—is important to many ...

A DROP of liquid heavier than water, for example blue or red ink, submerged quietly into still water, encounters the resistance of the medium and becomes flatter in its form in the course of its ...

Researchers at the Technion-Israel Institute of Technology have measured “dark points” inside light waves that appear to ...

Abstract: This letter proposes a new method for controlling the divergence angles of multimode orbital angular momentum (OAM) vortex beams. A geometric framework is established that allows for the ...

Event brings together government, industry, and academic leaders to advance U.S. optical components manufacturing.

Abstract: In recent years, electromagnetic (EM) vortex imaging has emerged as a novel technique in the field of radar super-resolution imaging. This approach fundamentally differs from conventional ...

Researchers have developed a unique method of strengthening microscopic 3D printed lattices. The space we’re talking about here is very small, something the researchers call “nanoarchitecture”.
