TL;DR: The recent advances in planar diffractive lenses (PDLs) are reviewed from a united theoretical account on diffraction-based focusing optics, and the underlying physics of nanofocusing via constructive or destructive interference is revealed.

TL;DR: In this paper, the effects of optical resonance and near field in the interaction of transparent particles on a substrate with laser light have been examined experimentally and theoretically, and it is found that pits can be created at the contacting point between the particle and the metallic surface by laser irradiation (KrF,λ=248 nm) with a single pulse.

TL;DR: It was found that the H2 evolution from water splitting was achieved by photocatalysis of heterostructured nanocomposites after sulfurization treatment and this synthetic methodology described herein promises to be an effective approach for fabricating variety of nanostructures for enhanced catalytic applications.

TL;DR: In this paper, the authors summarize the fundamental physical mechanisms and related applications of microspheres in two primary research directions: first, to focus light energy on the sample surface, which leads to nano-patterning and achieves a sub-100nm feature size and second, to manipulate light reflected back from the sample surfaces, which forms the foundation of super-resolution optical imaging to observe nano-structures.
