We demonstrate a compact all-fiber Er-doped chirped pulse amplification (CPA) system that can produce ∼344 fs pulses with an average power of up to 1.02 W and a repetition rate of 40.6 MHz at 1.56 μm ...

For much of the flight Fossett cruised at over 8,000 meters (26,240 feet) and breathed oxygen from a liquid oxygen system. The gondola was equipped with a bench and a sleeping bag.

A gradient HPLC approach in combination with a countergradient system for online biochemical detection (BCD) to screen for inhibitors of serine proteases is described. For gradient separations, this ...

NASA’s Voyager Probes Uncover a Mysterious “Wall of Fire” Beyond Our Solar System WW1 British shipwreck a 'ticking timebomb' as mission to investigate launched ...

Developing metal-free catalysts for oxygen reduction reaction (ORR) is a great challenge in the development of fuel cells. Nitrogen and sulfur codoped carbon with remarkably high nitrogen content up ...

The Oxygen Supply System to Hospitals is a critical infrastructure designed to provide a continuous and reliable supply of medical oxygen to patients in need of respiratory support. This system ...

Mixtures of cyclohexyl acetate and cyclohexanol were used as a mixed solvent to study liquid-liquid equilibria (LLE) of the acetic acid-water-cyclohexanol-cyclohexyl acetate quaternary system. The ...

This article aims to solve two intricate problems in nonlinear control: 1) the zero-division of the control by requiring its differentiability and 2) the finite-time stabilization via adaptive ...

Bipartisan legislation aims to restore access to lightweight liquid oxygen systems and respiratory therapy support, but needs more congressional sponsors to move forward ...
