Lignin has been widely used as a high-quality carbon source in the preparation of carbon electrodes. Because the skeleton of lignin molecules is an unordered three-dimensional network structure, it is difficult to obtain highperformance porous carbon electrode materials with regular structures by conventional carbonization methods. To improve the e...

The corrosion of carbon support is one of the key factors causing the deactivation of Pt-based oxygen reduction reaction (ORR) catalysts for proton exchange membrane fuel cells. In this work, a highly stable carbon support with a high graphitization degree, small diameter, and large surface area (polyaniline-based carbon nanofibers, CNF-1300-0.28Mn...

Recently, lithium-sulfur (Li-S) batteries have been demonstrated as promising next-generation energy-storage devices. However, their practical application is hindered by poor cycling performance and rate capability. In this study, we prepared a multifunctional interlayer composed of SnO2 nanowires (NWs) and conductive carbon paper (CP) to enhance t...

Although coke formation is one of the most important problems that the steam cracking process still faces, the properties of the formed coke have hardly been studied over the past decade. For some of them, orders of magnitude differences have been reported. Therefore, state-of-the-art measurement techniques have been used on industrially relevant s...

Properties of nanoparticles in contact with other surfaces are crucial for various applications. Here, we show that electrical potential of individual nanoparticles or their aggregates (sizes 5–50 nm) can be locally switched between negative and positive via work functions of surrounding materials (Si, Au, and Pt). We employed novel methodology of ...

The microstructure of carbon/carbon composites obtained by chemical vapor infiltration of carbon-fiber felts was studied comparatively by means of Raman spectroscopy, polarized light microscopy (PLM), scanning electron microscopy (SEM), and X-ray diffraction. The matrices, which are homogeneously textured according to PLM, exhibit pronounced spatia...

As part of the ongoing development at the AMS facility of the Center for Chronological Research at Nagoya University to radiocarbon (C-14) analyze samples smaller than 0.5 mg carbon (mgC), a compact graphitization manifold has been built. Tests with various reference materials show it performs well for samples as small as 0.1 mgC. Preparation with ...
