25 W of average power at 172 nm in the vacuum ultraviolet from flat, efficient lamps driven by interlaced arrays of microcavity plasmas

open access: yesAPL Photonics, 2017
More than 25 W of average power and >800 W of peak power have been generated at λ=172 nm (hν=7.2 eV) in the vacuum ultraviolet (VUV) from the Xe2 molecule in flat, 10 × 10 cm2 lamps having an active area and volume of 80 cm2 and 350 mW cm−2 in 40–60 μJ ...

Dynamic Illumination for Augmented Reality with Real-Time Interaction [PDF]

open access: yes, 2019
Current augmented and mixed reality systems suffer a lack of correct illumination modeling where the virtual objects render the same lighting condition as the real environment. While we are experiencing astonishing results from the entertainment industry

Integrase illuminated [PDF]

open access: yesEMBO reports, 2010
Antiretroviral drugs to prevent integration of the HIV viral genome into chromosomes are undergoing clinical trials, yet they have been developed with an imperfect understanding of their mechanism of action. The recent crystal structure of the major viral protein integrase from a related, little‐known retrovirus, has finally provided insight into how ...
