It was about 125 years ago that the light bulb was commercialized by Thomas Edison. No doubt a brilliant invention at the time, today its low power conversion efficiency is one of the reasons why lighting in the western world has such high energy consumpti ...
A clear signature of enhanced backscattering of excitons is observed in the directional resonant Rayleigh scattering of light from localized two-dimensional excitons in disordered quantum wells. Its spectral dependence and time dynamics are measured and th ...
OBJECTIVE: To assess the efficacy of a novel resorbable hydrogel barrier for preventing postoperative adhesions in animals. METHODS: A hydrogel barrier was formed in situ by photopolymerizing a solution of a macromolecular prepolymer in buffered saline usi ...
We examine the room-temperature dispersive and non-dispersive cathodoluminescent (CL) signals produced by an n-InP/n(+)-InP homojunction as a function of excitation beam energy. The non-intentionally doped epilayer of the homojunction is thick enough (2.5 ...
By using pyran-containing donor-acceptor dyes as doping molecules in organic light-emitting devices (OLEDs), we scrutinize the effects of charge trapping and polarization induced by the guest molecules in the electro-active host material. Laser dyes 4-(dic ...
Anidolic Daylighting Systems (ADS) typically reduce the daylight flux reaching an office room‟s window section and increase it in the rear of the room. They offer interesting possibilities for the combination of comfortable daylighting and highly energy-ef ...
Most energy saving applications of advanced fenestration systems (solar blinds, novel types of glazing and daylight redirecting devices) require a precise knowledge of their directional light transmission features. These photometric properties can be descr ...
Electric lighting is responsible for a significant fraction of electricity consumption within non-residential buildings. Making daylight more available in office and commercial buildings can lead as a consequence to important electricity savings, as well a ...
