Osaka Metropolitan University scientists succeeded in directly observing how LECs—which are attracting attention as one of the post-organic LEDs—change their electronic state over time during field emission by measuring their optical absorption via lamp light irradiation for the first time. This research method can be applied to all light-emitting devices, including not only LECs but also organic LEDs. This method is expected to reveal detailed electroluminescence processes and lead to the early detection of factors that reduce the efficiency of electroluminescence.

Amide bonds are important functional groups in medicinal chemistry and account for roughly 16% of all reactions performed in drug-discovery research. Some amide bond reactions using pharmaceutically important nitrogen-containing heterocyclic compounds, such as indole, carbazole and pyrrole, rather than amines are not efficient using conventional production methods. In a recent study, a team of leading chemists developed a novel one-pot reaction to efficiently form amide bonds using low-reactivity, nitrogen-containing heterocyclic compounds and carboxylic acid without special equipment or heat.

A research group from the Graduate School of Engineering at Osaka Metropolitan University has shown that 3C-SiC exhibits high thermal conductivity equivalent to the theoretical value, based on thermal conductivity evaluation and atomic-level analysis, for the first time. They demonstrated that a 3C-SiC film on silicon substrate had a high thermal conductivity and expect that fabricating large-diameter wafers can be achieved at a low cost. The discovery should lead to improved heat dissipation in everyday electronic devices.

The research team believes that this innovative method will shed light on strategies for fabricating a powerful research tool for uncovering the mysteries of electrochemical processes in the future.

Traditional hydrogen peroxide production is energy and emission intensive, and so scientists have sought to synthesize it electrochemically. But tailoring the cobalt-nitrogen-carbon (Co-N-C) catalyst has been challenging. Using a theoretical prediction, which was then experimentally verified, an international research group has designed a Co-N-C catalyst that alleviates this problem.

Organic photovoltaics (OPVs) are a promising, economical, next-generation solar cell technology for scalable clean energy and wearable electronics. But the energy conversion loss due to the recombination of photogenerated charge carriers in OPVs has hindered further enhancement of their power conversion efficiency (PCE). Recently, researchers from City University of Hong Kong (CityU) overcame this obstacle by inventing a novel device-engineering strategy to successfully suppress the energy conversion loss, resulting in record-breaking efficiency.

Everyday electronics, such as our phones, employ surface acoustic wave devices for frequency filtering and sensing. But this consumes a lot of energy, serving as a drain on battery life.

The Kailasanatha Temple at Ellora is the largest monolithic rock-cut monument in the world. Considered to represent the victory of its patrons, the Rashtrakuta Dynasty, over the Chalukyas, the temple is widely considered remarkable for its size, standing at 32 metres high and 78 metres long.

A research group, at the Osaka Metropolitan University Graduate School of Engineering, has succeeded in measuring spin transport in a thin film of αNPD molecules—a material well-known in organic light emitting diodes—at room temperature. They found that this thin molecular film has a spin diffusion length of approximately 62 nm, a length that could have practical applications in developing spintronics technology. In addition, while electricity has been used to control spin transport in the past, the thin molecular film used in this study is photoconductive, allowing spin transport control using visible light.
