When a biomaterial comes in contact with a biological body, biological substance denaturation will be concomitant with the physical interaction between the biomaterial surface and biological substance, such as blood protein denaturation resulting from electrical charge transfer. In this study, we investigated the relationship between the physical properties of amorphous hydrogenated carbon (a-C...

ABSTRACT Since radiocarbon accelerator mass spectrometry ( 14 C AMS) is considered a high-precision technique, reassessment of the measurement uncertainty has been topic interest. Scientists from analytical and metrological fields have developed top-down bottom-up approaches. The quoted error should approximate long-term repetitions approach in order to be realistic. novelty this paper that bot...

Abstract Petroleum pitch‐based graphite blocks (GBs) attract considerable attention owing to their low cost, high yield, and possible application as heat sink components. However, no studies have systematically investigated the particle size distribution of GBs, structures, relationship between structures thermal properties resulting from graphitization. Hence, herein, we present a novel method...

Hydrogels have emerged as promising supporting materials for wearable or implantable electronic devices, owing to their high biocompatibility. Among the many techniques patterning conductive structures on materials, laser-based graphitization allows simultaneous synthesis and of structures. Here, it has been demonstrated first time, direct hydrogels by graphitization, application this method fa...

A catalytic technique to enhance graphite formation in nongraphitizing carbons was adapted to work with three-dimensional wood-derived scaffolds. Unlike many synthetic graphite precursors, wood and other cellulosic carbons remain largely disordered after high temperature pyrolysis. Using a nickel nitrate liquid catalyst and controlled pyrolysis conditions, wood-derived scaffolds were produced s...
