The quantity of hydrogen absorbed is expressed in terms of alloy composition, either as an atomic ratio of hydrogen atoms to the number of atoms in the base metal alloy, or as the capacity of hydrogen in the alloy on a weight percent basis. ...
A sample compound, sulfamethoxazole, was chosen for illustration of the method because its elemental composition, C10H11N3O3S, contains the elements carbon, hydrogen, nitrogen, oxygen, and sulfur; all replaceable by a stable isotope. While multiple atoms of carbon, hydrogen, nitrogen, and oxygen ...
Molecular dynamics is applied to explore the deformation mechanism and crystal structure development of the AlCoCrFeNi high-entropy alloys under nanoimprinting. The influences of crystal structure, alloy composition, grain size, and twin boundary distanc
In the Cantor alloy, the distribution of the five constituent elements is relatively random and uniform. By contrast, in the CrFeCoNiPd alloy, in which the palladium atoms have a markedly different atomic size and electronegativity from the other elements, the homogeneity decreases considerably; all...
Total numbers of carbon, nitrogen, sulfur, and phosphorous atoms were derived for each sample by summing the number of each of these elements of all detected formula. A C : N ratio was then calculated for each sample by dividing the total number of C by the total number of N. Functional...
combining orbiter and lander elements, are aimed at studying the formation history of the Moon, the structure and dynamics of its tenuous exosphere, and the interaction of the Moon’s surface and exosphere with the different sources of plasma and radiation of its environment, including the solar ...
When modern DP steels with 0.08–0.12% C are heated to obtain the 30–50% austenite or more, almost double decrease in Cγ versus 0.5%) can alter the quantitative effect of a particular alloying element on hardenability of austenite. Considering detailed effects of individual elements, carbon ...
The Laves phase shows up in the high-entropy equiatomic alloys at a mean electron density of 6-7 e/a in the presence of atoms differing by more than 12% in size and having mixing enthalpy lower than -30 kJ/mol. It is revealed that the lattice parameter in bcc high-entropy equiatomic ...
These plasmas have much higher temperatures than industrial plasmas and are composed of light atoms, particularly hydrogen or its isotopes, and are designed to produce energy by means of a thermonuclear reaction. Figure 1 indicates some general groupings of industrial plasmas according to their applica...
A catalyst composition comprising molecular sieve particles in a matrix, at least 75% of the pore volume of the composition, as measured by mercury porosimetry, having a
