Transcriptomic profiling sheds light on the blue-light and red-light response of oyster mushroom (Pleurotus ostreatus)

open access: yesAMB Express, 2020
Blue light is an important environmental factor that induces mushroom primordium differentiation and fruiting body development. Although blue-light treatment has been applied for the production of oyster mushroom (Pleurotus ostreatus), the blue-light ...

Photochemical colour change for traditional watercolour pigments in low oxygen levels [PDF]

open access: yes, 2014
An investigation for light exposure on pigments in low-oxygen environments (in the range 0–5% oxygen) was conducted using a purpose-built automated microfadometer for a large sample set including multiple samples of traditional watercolour pigments from ...

Subadditive responses to extremely short blue and green pulsed light on visual evoked potentials, pupillary constriction and electroretinograms

open access: yesJournal of Physiological Anthropology, 2017
Background The simultaneous exposure to blue and green light was reported to result in less melatonin suppression than monochromatic exposure to blue or green light.

Kajian Area Penyinaran Dan Nilai Intensitas Pada Peralatan Blue Light Therapy

open access: yesMajalah Ilmiah Teknologi Elektro, 2018
The case of a yellow baby (hyperbilirubinemia) is one of the most common conditions in newborns. One of the measures to reduce bilirubin levels in a baby is by phototherapy using blue light therapy.

Randomized trial of polychromatic blue-enriched light for circadian phase shifting, melatonin suppression, and alerting responses. [PDF]

open access: yes, 2019
Wavelength comparisons have indicated that circadian phase-shifting and enhancement of subjective and EEG-correlates of alertness have a higher sensitivity to short wavelength visible light.

Enhanced frequency up-conversion in Rb vapor [PDF]

open access: yes, 2010
We demonstrate highly efficient generation of coherent 420nm light via up-conversion of near-infrared lasers in a hot rubidium vapor cell. By optimizing pump polarizations and frequencies we achieve a single-pass conversion efficiency of 260% per Watt ...

Growth, Water-Use Efficiency, Stomatal Conductance, and Nitrogen Uptake of Two Lettuce Cultivars Grown under Different Percentages of Blue and Red Light

open access: yesHorticulturae, 2018
The objective of this study was to characterize growth, water-use efficiency (WUE), stomatal conductance (gs), SPAD index values, and shoot nitrogen uptake of two lettuce cultivars grown under different percentages of blue and red light.

Supplemental Blue Light Frequencies Improve Ripening and Nutritional Qualities of Tomato Fruits

open access: yesFrontiers in Plant Science, 2022
Tomatoes (Solanum lycopersicum L. Micro-Tom) were grown in a plastic greenhouse. When plants anthesis, the 100 μmol m–2 s–1 blue light-emitting diode (LED) light (430 ± 10 nm) was supplemented from 6:00 to 18:00.

Inactivation of Campylobacter jejuni by exposure to high-intensity 405-nm visible light [PDF]

open access: yes, 2010
Although considerable research has been carried out on a range of environmental factors that impact on the survival of Campylobacter jejuni, there is limited information on the effects of violet/blue light on this pathogen. This investigation was carried

Ultra Bright LED Light Injection Calibration System for MINOS [PDF]

open access: yes, 1998
We describe here a proposal for a light injection calibration system for the MINOS detectors based on ultra bright blue LEDs as the light source. We have shown that these LEDs are bright enough to span over two orders of magnitude in light intensity ...
