INFLUENCE OF LIGHT EMITTING DIODE (LED) ON MICROALGAE
Journal of Chemical Engineering and Industrial Biotechnology, 2020 There are 150,000 microalgae species. Scientists identified and classified 30,000 species. Only 10–15 species are utilised and studied for wastewater treatment, biogas upgrading, biomass production, and lipid content. LED can raise microalgae performance to the highest.

Retinal damage induced by commercial light emitting diodes (LEDs) [PDF]
Free Radical Biology and Medicine, 2015 Spectra of "white LEDs" are characterized by an intense emission in the blue region of the visible spectrum, absent in daylight spectra. This blue component and the high intensity of emission are the main sources of concern about the health risks of LEDs with respect to their toxicity to the eye and the retina. The aim of our study was to elucidate the

Thin-film photonic crystal LEDs with enhanced directionality
, 2010 The use of photonic crystals for light extraction from light-emitting diodes (LEDs) gives the possibility to shape the farfield emission pattern. This is of particular interest for étendue-limited LED applications that require a more directional ...

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Enhanced light extraction by photonic quasi-crystals in GaN blue LEDs [PDF]
, 2009 The far-field profile of photonic quasi-crystal patterned and unpatterned LEDs, fabricated from commercial epitaxial substrates by electron beam lithography, has been measured prior to lapping and dicing. Emission enhancements reach a maximum of 62%, and

Light Emitting Diodes (LED) for Aqueous Light Bleaching of Paper [PDF]
Restaurator. International Journal for the Preservation of Library and Archival Material, 2019 Abstract High performance daylight LED lamps are compared with HID lamps for light bleaching of paper. The LED can be placed in closer proximity to the object than the HID lamps, causing a significantly increased, uniform light exposure.
