ABSTRACT: The objective of this study is to improve fatigue life of T-shape arc welded joint structures which are often used in automobiles. In conventional T-shape joint, ST-joint (Standard T-joint), a vertical part is welded to a flat surface in th

Warm forming at temperatures from 200 °C to 600 °C has several advantages compared with cold forming at room temperature: better shape accuracy, better stretch flange formability and lower press load. In this study, the stretch formability of uncoa

We have constructed a sheet-type glucose/dioxygen enzymatic biofuel cell with multi-stacked structure, in which one biocathode is sandwiched with two bioanodes in parallel. The energy density of the biofuel cell reached 14.1 mWh cm−3. The cell has

A passive-type air-breathing biocathode using bilirubin oxidase as enzyme, ferricyanide as redox mediator, and poly-l-lysine as linker was investigated. Water-repellents from Scotchgard™ with dissolved in methyl isobutyl ketone were directly applie

Biofuel cell is a next-generation energy device that generates the electricity from renewable fuels such as glucose using redox enzymes as electrode catalyses. We re-constructed in vitro pentose phosphate pathway for 24-e oxidation of glucose-6-phosp

The mediated electro-enzymatic electrolysis systems based on the tricarboxylic acid (TCA) cycle reaction were examined on a micro-bulk electrolytic system. A series of the enzyme-catalyzed reactions in the TCA cycle was coupled with electrode reactio

Biofuel cells are a next-generation energy device because they use renewable fuels with high energy density and safety. We have developed passive-type biofuel cell units, which generate a power over 100 mW (80 cm3, 39.7 g). Our biofuel cell, in which

We have developed the passive-type biofuel cell having 3.0mW/cm2 power at 500 mV and 800 mV open circuit voltage. This performance has been achieved by introducing 2-amino-1,4-naphthoquinone (ANQ) as an anode electron mediator. Although the redox pot
