The increasing demand for the high energy density of lithium-ion batteries gives rise to the development of larger particle sizes of the active electrode materials. 20μm-sized Li(Co1−xLix)O2−δ agglomerates are synthesized via solid-state reactions with different nominal compositions (Li/Co=1.00, 1.02, and 1.05) at 1000°C for 5h in ambient air while suppressing the lithium vaporization. Careful inductively...
To obtain high performance in nMOSFETs, the introduction of high-mobility channel material such as InGaAs is a promising approach. However, the required source doping concentration for a high driving current cannot be obtained by ion implantation in InGaAs. One method of achieving a heavily doped source in III–V semiconductor MOSFETs is by growing an epitaxial source/drain structure.1 For realizing...
"Bot", automatic robot software, has been one of most serious problems in Massively Multiplayer Online Role Playing Game (MMORPG). Bots earn much more money in a virtual world than human players, and finally collapse balance and fairness of the MMORPG. At present, many techniques have been applied to detect and exterminate bots. However, they have a common problem that the technique effective...
Human neutrophil antigens (HNAs) play an important role in a variety of clinical conditions including immune‐mediated neutropenia, non‐hemolytic transfusion reactions, and transfusion‐related acute lung injury. The aim of this study was to investigate the frequency distribution of HNAs‐1 to ‐5 among the Japanese population. We analyzed samples from 570 healthy Japanese by molecular and serologic techniques...
A Langevin-type broadband transducer was developed using a multilayer piezoelectric actuator (hereafter referred to as a multilayer piezoelectric element). The frequency range of the broadband transducer was aimed to cover the frequency range from 38 to 120 kHz typically used for sensing fish and zooplankton. The 10-mm long multilayer piezoelectric elements whose resonance frequency is 138 kHz were...
