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.
Thermal conductivity of 3C-SiC compared to other semiconductor materials
13 Feb 2023
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.

Schematic illustration of the spin transport demonstration of αNPD molecular thin film
24 Jan 2023
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.
