Desenvolvimento de um painel modular de LED
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Eletrotécnica, 2013-12-19)
This work consists of a modular and interactive LED (light emitting diode) panel development. Electronics circuits for power supply, infrared communication and LED matrix control were developed. Furthermore, it was also ...
Polymer light emitting devices with Langmuir Blodgett (LB) films of a polyfluorene derivative
(2005-12-01)
Polyfluorenes are promising materials for the emitting layer of polymer light emitting devices (PLEDs) with blue emission. In this work, we report on PLEDs fabricated with Langmuir-Blodgett (LB) films of a polyfluorene ...

Woven‐fiber microfiltration (Wfmf) and ultraviolet light emitting diodes (uv leds) for treating wastewater and septic tank effluent
(MDPI, 2021)
Decentralized wastewater treatment systems enable wastewater to be treated at the source for cleaner discharge into the environment, protecting public health while allowing for reuse for agricultural and other purposes. ...
Effect of phototherapy with light-emitting diodes (890 nm) on tendon repair: an experimental model in sheep
(Springer, 2015-01-01)
The effect of phototherapy with 890-nm light-emitting diodes (LEDs) on the healing of experimentally induced tendinitis in sheep was evaluated in this study. Partial tenotomies measuring 0.2 cm wide x 0.5 cm long were ...
Photoprotective effect of mycosporine-like aminoacids extracts on natamycin, saffron carotenoids and epigallocatechin gallate in acidified beverages exposed to different light sources
(2019-02-01)
Natamycin has been used as a natural food additive to control the growth of many microorganisms. However, this polyene is very sensitive to light exposure. Therefore, the objective of this study was to evaluate the ...
