Design of high power LED-based UVA emission system and a photosensitive substance for clinical application in corneal radiation
(Spie-int Soc Optical Engineering, 2015-01-01)
This work presents an innovative cross-linking procedure to keratoconus treatment, a corneal disease. It includes the development of an ultraviolet controlled emission portable device based on LED source and a new formulation ...
Influence of irradiation sources on the efficiency of copper-modified magnetite for photo-Fenton degradation of sulfathiazole
(2020-01-01)
A comparison of the catalytic activity of the copper-modified magnetite was carried out under different conditions (dark and irradiated) and irradiation systems (460 nm Vis-LED, 370 nm UV-LED and Solar) in the degradation ...
Uso de trampas con atrayentes semioquímicos más luz LED-UV para el monitoreo de polilla del racimo de la vid (Lobesia botrana)

The Use of Genetic Algorithms in UV Disinfection of Drinking Water
In order to have drinking water, some countries
have to use chlorine. It is use cause is effective and it’s cheap. An
alternative to this process is the UV disinfection of drinking
water. Most of the devices in the ...
Eu(II)-Activated Silicates for UV Light-Emitting Diodes Tuning into Warm White Light
(2020-08-01)
White-light-emitting diodes (WLEDs) are the main white light source for general lighting due to high-luminous efficacy (>150 lm W−1), long lifespan (5 × 104 h), and environmentally friendly properties. Despite the current ...
Utilización de luces LED UV para aumentar la captura de la polilla de la manzana (Cydia pomonella) en trampas con cebos atrayentes
(Universidad de Talca (Chile). Escuela de Agronomía., 2022)
Red-Emitting Coatings for Multifunctional UV/Red Emitting LEDs Applied in Plant Circadian Rhythm Control
(2020-01-01)
Multifunctional light-emitting diodes (LEDs) formed by coating deep-UV-emitting (<300 nm) LED chips with downshifting phosphors are of great interest for applications in indoor farms as both antibacterial (UV radiation) ...
Effect of UV-B radiation on the contents of UV-B absorbing compounds and photosynthetic parameters in Parmotrema austrosinense from two contrasting habitats
(Wiley Blackwell Publishing, Inc, 2018-09)
We studied the resistance of Parmotrema austrosinense to UV-B stress. We focused on the effects of a high dose UV-B radiation on the content of chlorophylls, carotenoids and UV-B screening compounds. Photosynthetic parameters ...
Syntheses and characterization of Schiff base ligands and their Ir(III) complexes as coating for phosphor-converted LEDs
(2020-10-01)
Ir(III) complexes find several applications in light conversion molecular devices (LCMD) such as in solid-state lighting (SSL). Although, a couple of blue or green-emitting Ir(III) complexes are found so far, there is a ...
