First results on the ion mass distribution from methane ECR plasmas were published by Amemiya et al. [89]. They qualitatively measured the composition of the ion flux for hydrogen and methane and some other gases. In hydrogen plasmas H+, H+2, and H+3 prevail, with the relative contribution...
Comparison between theory and experiment serves not only as a consistency check between them, but it can also potentially be exploited to determine physical constants such as the proton charge radius, the electron–proton mass ratio, or the Rydberg constant R∞. In this review, we want to ...
Flint, Michigan’s Mass Transportation Authority (MTA) is embarking on a significant step toward greener public transit. With an $11 million… November 22, 20240 The Art of Steel Meets Hydrogen Innovation in the Hyundai Initium SUV ByDan Holguin ...
Hydrogen is the most abundant chemical element, constituting roughly 75% of the universe's elemental mass. Stars in the main sequence are mainly composed of hydrogen in its plasma state. Elemental hydrogen is relatively rare on Earth. Industrial production is from hydrocarbons such as methane with...
In comparison, the relatively lower mass intensities of VnOH2O+ presumably correspond to the intermediates of a successive reaction of VnO+ with a second H2O molecule that ultimately may lead to the removal of the second H2. The observation of VnO3+ shows the ability of Vn+ to produce three...
Porous nanomaterials (photocatalysts) generally outperform nonporous counterparts, both in environmental and energy applications [128]. This is due to their large specific surface areas and the presence of numerous pores, which enable efficient mass capture and diffusion, leading to enhanced photocatalytic...
Hydrogen mass diffusivity in air 0.61 cm2.s−1 is also 4 times faster than CH4, CO2 or even Ar. It means that in case of hydrogen leak (fracture of the gas holder), in an outside environment hydrogen diffuse rapidly and empty the container which lead to nothing dangerous except if ...
{2}}\)at the anode is over 91.0%. Since the Faradaic efficiency of both H2and O2measured and calculated by energy and mass balances are comparable, we again confirm the overall electrolysis is a water-splitting process. After keeping the above DAE module unattended in air for 8 months, ...
of natural organic matter (NOM) based on our previously developed simple hydrogen/deuterium (H/D) exchange (electrospray ionization (ESI) ion source (Kostyukevich et al. Anal. Chem. 2013, 85, 5330) and ultra-high-resolution Fourier transform ion cyclotron resonance mass spectrometry is presented...
Formation of Low-Mass X-Ray Binaries. I. Constraints on Hydrogen-rich Donors at the Onset of the X-Ray Phase We identify and quantify the set of constraints that neutron star-normal star binaries must satisfy in order to become observable LMXBs. These constraints ... V Kalogera,RF Webbin...
