Metasurfaces, ultra-thin films of nanostructures, hold immense promise for manipulating light with unprecedented control. However, their full potential hinges on overcoming the challenge of crafting these intricate patterns at large scales and high resolutions. This review explores the current nanofabrication techniques, including maskless and masked lithography, exploring their strengths and limitations. By understanding these constraints, we can pave the way for advanced nanophotonic applications powered by these light-bending marvels.

Monkeypox virus (mpoxv) has re-emerged, designated on August 14 as a global emergency by the World Health Organization. Newly evolved strains of mpox viruses can efficiently spread among people. In addition to skin rashes, mpox infection can cause eye complications including inflammation of the clear tissue covering the iris and pupil called the cornea (keratitis), the tissue covering the white of the eye and the underside of the eyelid (conjunctivitis, or pink eye), and the eyelid (blepharitis).

In the agricultural and food industry, determining the chemical composition of raw materials is important for production efficiency, application, and price. Traditional laboratory testing is time-consuming, complicated, and expensive. New research from the University of Illinois Urbana-Champaign demonstrates that near-infrared (NIR) spectroscopy and machine learning can provide quick, accurate, and cost-effective product analysis.

Lawrence Livermore National Laboratory scientists and engineers have earned three R&D 100 awards from the trade journal R&D World Magazine. The LLNL awards include a spectral beam combining optic that enables a single, high-power beam with unparalleled compactness and damage resistance; an open-source memory-mapping library with increased power and flexibility; and a user-level file system for high performance computing systems. With this year’s results, the Laboratory has now collected a total of 182 R&D 100 awards since 1978.
