Backbone Heterojunction Photocatalysts for Efficient Sacrificial Hydrogen Production

Advanced Functional Materials, EarlyView.
Herein, a ‘single‐component’ organic semiconductor photocatalyst is presented in which a molecular donor is bonded to a polymer acceptor. The resultant material demonstrates exceptional photocatalytic activity for hydrogen evolution in aqueous triethylamine with an outstanding external quantum efficiency of 38% at 420 nm.

Intensity mapping optical aberrations

Applied Optics, 1978
Intensity mapping aberrations for high average power laser beams are examined from the point of view of diffraction theory. For the Fresnel ripple aberrations, it was determined that indeed they behave like a circular diffraction grating where energy is diffracted into the far wings of the far-field intensity distribution without significantly ...

Aberrations of optical domes

SPIE Proceedings, 1998
Optical domes have traditionally been sections of concentric spheres or hemispheres. The concentric spherical shape facilitates the optical system design following the protective dome as well as the fabrication of the dome. Very little attention has been given to optimizing the aerodynamic performance of optical domes.
