The confluence of high-temperature (~1600–3200 K) flameless combustion chambers and vertical-junction (VJ) photovoltaics creates the possibility of ultra-compact high-efficiency thermophotovoltaic (TPV) generators. The actively-cooled cells can be

Thin liquid sheet jet flows in vacuum provide a new platform for performing experiments in the liquid phase, for example X-ray spectroscopy. Micrometer thickness, high stability, and optical flatness are the key characteristics required for successfu

Recently two emerging areas of research, attosecond and nanoscale physics, have started to come together. Attosecond physics deals with phenomena occurring when ultrashort laser pulses, with duration on the femto- and sub-femtosecond time scales, int

A challenge for design, testing, and fabrication of nanostructured chemical sensors is the fabrication of mm2 size arrays of nanostructures in a reasonable time. Herein, we introduce and show how direct laser writing (DLW) in positive-tone photoresis

We show that the radiation-hardness of space solar cells can be significantly improved by employing nanophotonic light trapping. Two light-trapping structures are investigated in this work. In the first, an array of Al nanoparticles is embedded withi
