Inverted Fluorescence
Discovery of chromophores that emit light in the ultraviolet region when excited with visible light
23-Dec-2020
Fluorescence usually entails the conversion of light at shorter wavelengths to light at longer wavelengths. Scientists have now discovered a chromophore system that goes the other way around. When excited by visible light, the fluorescent dyes emit light in the ultraviolet region. According to ...
Molecular twist makes one catalyst useful for three hydrogen applications
"In a way, we've created a molecule with a steering wheel on it"
12-Jun-2020
Scientists from Kyushu University and Kumamoto University in Japan have developed a new catalyst capable of assisting three key reactions for using hydrogen in energy and industry. Inspired by three types of enzymes in nature, this research can help elucidate unknown relationships among ...
Atomically precise models improve understanding of fuel cells
Computer simulations using models based on real-world atomic structures from microscope observations shed new light on the reaction pathways in fuel cells
23-Jul-2019
Simulations from researchers in Japan provide new insights into the reactions occurring in solid-oxide fuel cells by using realistic atomic-scale models of the active site at the electrode based on microscope observations as the starting point. This better understanding could give clues on ways ...
Organic laser diodes move from dream to reality
03-Jun-2019
Researchers from Japan have demonstrated that a long-elusive kind of laser diode based on organic semiconductors is indeed possible, paving the way for the further expansion of lasers in applications such as biosensing, displays, healthcare, and optical communications. Long considered a holy ...
Smart Fluorescent Dyes
Modulating photo- and electroluminescence in a stimuli-responsive molecular dye
17-Aug-2018
Controlling the excited electronic states in luminescent systems remains a challenge in the development of fluorescent and phosphorescent dyes. Now, scientists in Japan have developed a unique organic fluorophore that changes its emission color without loss of efficiency when externally ...
Multifunctional catalyst for poison-resistant hydrogen fuel cells
28-Jun-2017
Japanese collaboration develops catalyst that can oxidize both hydrogen and carbon monoxide to produce energy Demand for eco-friendly fuel sources is increasing as the goal of weaning off our reliance on fossil fuels becomes commonly recognized. Hydrogen represents a possible sustainable fuel ...
