Novel strategy for the generation of highly energetic UV light
Many photochemical processes rely on UV light from inefficient or toxic light sources that the LED technology cannot replace for technical reasons. An international team of scientists led by Professor Christoph Kerzig of Johannes Gutenberg University Mainz (JGU) in Germany and Professor Nobuhiro ...
Researchers develop an olfactory sensor using your unique chemical composition to confirm who you are
Biometric authentication like fingerprint and iris scans are a staple of any spy movie, and trying to circumvent those security measures is often a core plot point. But these days the technology is not limited to spies, as fingerprint verification and facial recognition are now common features on ...
By tweaking the emission mechanism and the molecules used, researchers improved the performance of organic glow-in-the-dark materials by tenfold
Glow-in-the-dark materials are utilized worldwide for emergency signs, watches, and paint. This useful characteristic fuels a global market worth approximately US$400 million. But the inorganic crystals that are currently needed to generate this ability to a high level of performance require ...
Discovery of chromophores that emit light in the ultraviolet region when excited with visible light
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 ...
"In a way, we've created a molecule with a steering wheel on it"
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 ...
New approach eases manufacturing constraints and improves viewing angle with little effect on performance
By combining thin organic layers with thick layers of hybrid perovskite, researchers at Kyushu University in Japan have developed micrometer-thick organic light-emitting diodes that could improve the affordability and viewing angles of high-performance displays and televisions in the near ...
Computer simulations using models based on real-world atomic structures from microscope observations shed new light on the reaction pathways in fuel cells
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 ...
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 ...
Modulating photo- and electroluminescence in a stimuli-responsive molecular dye
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 ...
Renewed investigation of a molecule that was originally synthesized with the goal of creating a unique light-absorbing pigment has led to the establishment of a novel design strategy for efficient light-emitting molecules with applications in next-generation displays and lighting. Researchers at ...
