Can red flowers be conspicuous to bees? Bombus dahlbomii and south american temperate forest flowers as a case in point
(COMPANY OF BIOLOGISTS LTD, 2010)
It has been argued that trichromatic bees with photoreceptor spectral sensitivity peaks in the ultraviolet (UV), blue and green areas of the spectrum are blind to long wavelengths (red to humans). South American temperate ...
Computational analysis on D–π–A based perylene organic efficient sensitizer in dye-sensitized solar cells
(2020-03-01)
We designed and screened a series of metal-free organic dyes with different tunable donors (D1–D3) based on literature dye (3a). The D1–D3 organic dyes have been applied in dye-sensitized solar cells (DSSCs). Triphenylamine, ...
Pigments from UV-resistant Antarctic bacteria as photosensitizers in Dye Sensitized Solar Cells
(2016)
Here we report the use of pigments produced by UV-resistant Antarctic bacteria as photosensitizers in Dye Sensitized Solar Cells (DSSCs). Pigments were obtained from red and yellow colored psychrotolerant bacteria isolated ...
PHOTOBIOCHEMISTRY IN THE DARK - PHOTOHEMOLYSIS OF RED-CELLS SENSITIZED BY CHLORPROMAZINE-BIOENERGIZED TRIPLET ACETONE SYSTEM

Sensitized thulium blue and red upconversion emission and energy-transfer processes in Nd3+/Yb3+/Tm3+-codoped PbGeO3-based glass excited around 800 nm
(2003-01-01)
This paper reports on the generation of bright blue and red upconversion luminescence through the sensitization of thulium ions in Nd3+Yb3+Tm3+ triply-doped 70%XoPbGeO3:15%PbF2:15%CdF2-glass excited by a diode laser source ...
A Combination of Solid Mandels Medium, CMC, and Congo Red Technique for Rapid, Sensitive and Reproducible Screening of Cellulase-Producing Fungi
(Biogeneric Publishers, 2020-11)
The bioconversion of lignocellulosic biomass into monomeric sugars, by the action of cellulase enzymes, is the main economic problem hindering the profitable use of this abundant source of energy. Trichoderma genus is ...
The influence of the loop between residues 223-235 in beetle luciferase bioluminescence spectra: A solvent gate for the active site of pH-sensitive luciferases
(2008-01-01)
Beetle luciferases emit a wide range of bioluminescence colors, ranging from green to red. Firefly luciferases can shift the spectrum to red in response to pH and temperature changes, whereas click beetle and railroadworm ...
