Hydrogen Gas Cutting System
Recently, the introduction of advanced “Hydrogen Gas Cutting” was investigated but finally abandoned due to the problems of several accidents occurred, cost merit and safety. The facility is called “Hydrogen-Oxygen Mixture Gas Generation System” and stores the hydrogen detonating gas (when hydrogen and oxygen are mixed to 2:1 in volume ratio, the mixture gas violently explodes if ignited), so t...
متن کاملAcoustic Wave Hydrogen Gas Sensors
Amorphous titanium dioxide (TiO2) and gold (Au) doped TiO2-based surface acoustic wave (SAW) sensors have been investigated as hydrogen gas detectors. The nanocrystal-doped TiO2 films were synthesized through a sol-gel route, mixing a Ti-butoxide-based solution with diluted colloidal gold nanoparticles. The films were deposited via spin coating onto 64◦ YX LiNbO3 SAW transducers in a helium atm...
متن کاملProtective Effects of Hydrogen Gas on Experimental Acute Pancreatitis
Acute pancreatitis (AP) is an inflammatory disease mediated by damage to acinar cells and pancreatic inflammation. In patients with AP, subsequent systemic inflammatory responses and multiple organs dysfunction commonly occur. Interactions between cytokines and oxidative stress greatly contribute to the amplification of uncontrolled inflammatory responses. Molecular hydrogen (H2) is a potent fr...

متن کاملGas diffusion electrodes improve hydrogen gas mass transfer for a hydrogen oxidizing bioanode
Background Bioelectrochemical systems (BESs) are capable of recovery of metals at a cathode through oxidation of organic substrate at an anode. Recently, also hydrogen gas was used as an electron donor for recovery of copper in BESs. Oxidation of hydrogen gas produced a current density of 0.8 A m-2 and combined with Cu2+ reduction at the cathode, produced 0.25 W m-2. The main factor limiting cu...
