Hydrogen sulphid bears the reputation of being a decidedly toxic compound. Aside from its occasional occurrence as an occluded gas in coal seams and in mines, it is produced by decomposition of pyrites in the presence of moisture. Although the opportunities for poisoning with hydrogen sulphid in...
Hydrogen peroxide makes a great substitute for bleach, especially in a pinch. Just make sure to test the fabrics first or only use it on whites, because it can stain dark fabrics. Hydrogen peroxide is also a more environmentally friendly product than bleach, so you can feel g...
A derivation is given of the exact form of the three-body Coulomb wavefunction in the asymptotic region where the separation of all particles tends to infi... M Brauner,JS Briggs,H Klar - 《Journal of Physics B》 被引量: 405发表: 1999年 Ionization of hydrogen by positron impact near the...
While we’re at it, you can also use hydrogen peroxide drops in your ear to take on an ear infection. Just know that you may need medical attention; you cannot cure all ear infections on your own, and they can get serious. So don’t let this stop you from going to the doctor! Cl...

Plus, it’s non-toxic and safe to use orally, so you don’t have to worry about swallowing any harmful chemicals. Shutterstock To create the solution, mix equal parts peroxide and water in a small glass and soak the retainer for 30 minutes. All of the bubbles you see are fizzing ...
Interestingly, the NiPS/NF catalyst also performed well even with alkaline seawater as the electrolyte, thus proving its potential use in the direct electrolysis of seawater. Actual performance in full-cell seawater electrolysis was also evaluated; the NiPS/NF catalyst only required 1.66 V to reach...
The CSIRO announced earlier in August that it had successfully turned hydrogen into ammonia and back again using membrane technology in a world first that will allow hydrogen to be safely shipped worldwide for use as a zero emission fuel. ...
Through an in-depth analysis of preclinical and clinical studies, we aim to provide insights into the promising use of hydrogen as an adjunct therapy in transplantation. 2. Challenges in Organ Transplantation Organ transplantation failures result from a range of immunological and non-immunological ...
The atomic density of hydrogen in many metal hydrides is greater than inliquid hydrogenor in water. Metal hydrides are efficient moderators and neutron shielding materials and are particularly suitable for minimizing the core shield volume. Examples of the use of metal hydrides as moderators include ...
