Electrochemical properties of all-solid-state lithium batteries using lithium borohydride (LiBH4) as a solid electrolyte are presented for the first time. Despite its high conductivity and good compatibility with a lithium electrode, LiBH4 has not been considered suitable for practical applications partly due to its high reducing capability when used with metal oxides. In our investigation, it was confirmed that contact between this hydride solid lithium ion conductor and LiCoO2 results in a large ...

A pathogenic role of intraglomerular plasmin bound to nephritogenic antigen (nephritis-associated plasmin receptor, NAPlr) and resistant to physiologic inhibitors such as alpha(2)-antiplasmin (alpha(2)-AP) has recently been proposed in acute poststreptococcal glomerulonephritis (APSGN). To confirm this concept, we analysed the urinary profile of plasmin cascade in APSGN patients.Urine samples from 10 patients with APSGN, 12 patients with IgA nephropathy (IgAN), 10 patients with streptococcal infection ...

Turbulence characteristics of a natural-convection boundary layer in air along a vertical plate heated at high temperatures are experimentally investigated. Two-dimensional velocity vectors and instantaneous temperature in the boundary layer at a wall temperature up to 300 °C are measured using a particle image velocimetry and a cold wire. From the correlation between the local Nusselt number Nux and the local Grashof number Grx, it was found that heat transfer rates even for a wall temperature of ...

Fluid flow and heat transfer characteristics in a turbulent combined-convection boundary layer in air along a vertical heated plate have been investigated with normal hot and cold wires. The measured heat transfer rates and turbulent quantities show that the turbulent transition moves downstream with a slight increase in freestream velocity. Then, the heat transfer rate rapidly decreases to about 40% of that obtained in the turbulent natural-convection boundary layer, and velocity and temperature ...

Abstract After peripheral nerve injury, minimizing axonal misdirection has been a matter of importance to obtain good functional outcomes. In general, it becomes more challenging as the nerve defect length is longer. As previous works suggested that a conduit repair leaving a short gap could induce some target‐specific reinnervation, we expected that a distally placed conduit combined with nerve graft would enhance the specificity of reinnervation, especially in dealing with a long gap. To test ...

This paper describes a three-dimensional (3-D) system integration of a full-fledged processor chip and two memory chips using inductive coupling. To attain a 3-D communication link with a smaller area and lower power-consumption, shortening the link distance and preventing signal degradation due to unused inductors are important challenges. Therefore, we developed a new 3D-integrated wire-penetrated multi-layer structure for a shorter link distance and an open-skipped-inductor scheme for suppressing ...

Hierarchical power distribution with a power tree has been developed. The key features are a power-tree structure with three power-tree management rules and a distributed common power domain implementation. The hierarchical power distribution supports a fine-grained power gating with dozens of power domains, which is analogous to a fine-grained clock gating. Leakage currents of a 1 000 000-gate power domain were effectively reduced to 1/4000 in multi-CPU SoCs with minimal area overhead

Abstract Four different biofilter packing materials (two porous ceramics, perlite, and open pore polyurethane foam) were compared for the removal of toluene vapors. The focus was on evaluating performance at relatively short gas retention time (13.5 and 27 sec). The reactors were initially operated as biotrickling filters with continuous feeding and trickling of a nutrient solution. After significant plugging of the biotrickling filter beds with biomass was observed, the operation mode was switched ...
