Sentences with phrase «hydrogen and oxygen without»

A new robust and highly active bifunctional catalyst developed by Rice University and the University of Houston splits water into hydrogen and oxygen without the need for expensive metals such as platinum.

Not exact matches

Unlike ice sanitizing technologies that use UV light or other sources that create ozone, which can be hazardous to health, the patent - pending BPi200 uses a small electrical housing and carbon - fiber brushes to release airborne positive hydrogen and negative oxygen ions throughout the ice machine without creating ozone.

«Without a membrane, the photoanode and photocathode are close enough to each other to conduct electricity, and if you also have bubbles of highly reactive hydrogen and oxygen gases being produced in the same place at the same time, that is a recipe for disaster,» Lewis says.

Yet without a protective magnetic field to shield the surface, ionizing radiation started splitting water molecules into hydrogen and oxygen.

Tests by Bao's lab compared nickel foam and the phosphide both with and without graphene in the middle and found the conductive graphene lowered charge - transfer resistance for both hydrogen and oxygen reactions.

Some microbes merged with hydrogen - producing microbes (probably multi-functional ancestral mitochondria) to become eukaryotes that later developed into multi-cellular «animals» that survive and breed in anoxic conditions, without oxygen (phylum Loricifera, which includes Spinoloricus at left — more).

«Without a membrane, the photoanode and photocathode are close enough to each other to conduct electricity, and if you also have bubbles of highly reactive hydrogen and oxygen gases being produced in the same place at the same time, that is a recipe for disaster,» Lewis says regarding his findings published in PNAS.

If you can make them use the water environment as fuel to catalyze a chemical reaction, then can you make a version that functions to break up water to hydrogen and oxygen for green energy generation without having to add the required energy directly?

Without the mixing of the deep water and the water at the surface, oxygen can not reach a depth greater than 300 feet, leaving the waters of the deep either too high in Hydrogen Sulfide, or too low in oxygen to sustain life forms (zambiatourism).

In fact, certain of TEPCO's actions in the aftermath of the explosions have been confused and, some might opine, lacking discipline of purpose to the extent that expedient decisions have been made without proper forethought and judiciousness to avoid knock - on consequences: for example, the injection of seawater may have resulted in salt deposits sufficient to foul cooling flows in the lower regions of the RPV [reactor pressure vessel]; the liberation of hydrogen from seawater is more rampant than from freshwater and radiolysis of oxygen from the cooling water could provide stoichiometric conditions and ignition with hydrogen in the absence of air in the containments; and the latest and most recent announcement to deploy a nitrogen purge to the Unit 1 reactor seems yet another ill - explained and unjustified desperate measure».
