A detailed atomic-scale description of the electrochemical interface is essential to the understanding of electrochemical energy transformations. In this work, we investigate the charge of solvated protons at the Pt(111) | H2O and Al(111) | H2O interfaces. Using semi-local density-functional theory...
Charge-exchange-induced perturbations of ion and atom distribution functions in the heliospheric interface Different hydrodynamic models of the heliospheric interface have been presented meanwhile, numerically simulating the interaction of the solar wind plasma ...

have demonstrated significant advantages of esomeprazole and rabeprazole compared with the older PPIs, which omeprazole is the prototype: a greater inhibition of acid secretion, a more rapid onset of action to provide reflux symptoms relief over 24 hours with lower GERD-related cost for rabeprazole, ...
Atoms are comprised of three basic components. In the nucleus, there are protons (positive charge) and neutrons (no charge). These are where the vast majority of the weight is and will determine what type of atom this is. Electrons (negatively charged) orbit relatively far away from the nuc...
In this work, we tested a setup of X-ray fluorescence (XRF) excited by proton-induced quasi-monochromatic X-rays (proton-induced XRF (PIXRF)) as a low-radiation dose analytical technique for precious cultural heritage samples. The low-dose performance of
A few studies have so far provided a clear or limited explanation for such phenomena. In this work, the response mechanisms of hydrogel ionotronics to T&RH changes were examined by combining the experimental characterization with the theoretical modeling. Silk fibroin hydrogel ionotronics (SFHIs) ...
A new substance has been found with 73 protons and an atomic mass of 192. How many neutrons does it have? The mass number of an element can be easily approximated by adding together the number of ___ in an atom of that element. A) protons and neutrons B) energy levels C) protons...
In parton-oriented models the concept of "di-quark" fragmen- tation is usually invoked which necessitates the establish- ment of fragmentation functions which have to be extracted from the hadronic measurements proper and cannot rely on independent evaluation as in the case of quark fragmenta- ...
Why don t atoms gain or lose protons?Atoms never gain protons; they become positively charge only by losing electrons. A positive ion is called a cation (pronounced: CAT-eye-on). You may have notice that the number of neutrons in each of these ions was not specified. ...
Atomic structure Grams are not used to measure mass of atoms because atoms are too small –Amu is used instead –Amu = atomic mass unit Amu – 1/12 th the mass of a carbon-12 atom, which contains 6 protons and 6 neutrons Isotopes Isotopes are atoms that have the same number of proton...
