The objective of this article is to show how experimental discoveries in atomic physics are logically connected, and we land up with the consistent theoretical explanation to the structure and stability of the atom. It is also shown that Bohr's correspondence principle and Erhenfest's adiabatic ...
[217] calculated the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) activities of 224 carbon-based single-atom catalysts (SACs, 8 carbon carrier materials including MOFs * 28 excess metal atoms). They trained seven regression models using 202 chemical descriptors as input ...
Recently, a structural modification has achieved an additional degree of freedom in TMD ML, causing out-of-plane asymmetry to form the so-called Janus ML17. This family has the general formula XMY and can be obtained by the substitution of one chalcogen atom of the single triple-layer18. Si...
of-plane conductivity forn = 1 2D materials, it is still lower than that of 3D materials22. Both in-plane and out-of-plane conductivities increase while the anisotropy in two directions decreases with increasingn22. While pure phase perovskites with n > 1 are also crystallographically ...
Ideal, resistive and kinetic MHD instabilities are described. Since the birth of steady state tokamak tokamak research in 1990, there are number of important understandings of MHD modes related to steady state tokamak. In Sect.
Physicists have created one of the heaviest elements yet, an atom with 117 protons in its nucleus. This jumbo-sized atom sits on the outer reaches of the periodic table where bloated nuclei tend to become less and less stable. Element 117’s existence gives scientists hope, however, that the...
We describe here a method to calculate the critical nuclear charge for which an atom can bind an extra electron to form a stable negative ion. The estimate of the critical nuclear charge will be used to explain and predict the stability of atomic negative ions. The method can be generalized...
The thermal stability and folding kinetics of a 15-residue β-hairpin (SESYINPDGTWTVTE) have been studied by using infrared (IR) spectroscopy coupled with laser-induced temperature-jump (T-jump) technique for rapid folding−unfolding initiation. An alternative method based on analyzing IR differen...
This work not only provides a facile entry to develop stable heterogeneous catalyst for solid–liquid catalysis, but also establishes an efficient route to synthesize various indole-derived carbonyl compounds, which have wide applications in the preparation of bioactive compounds. Fig. 2: Structure and...
The probability distribution of GS/LS-NASICONs are plotted with contour lines. The contours toward the center are of higher probability. Two groups of representative NASICONs are highlighted, i.e., A (NaHfMg(SO4)2(PO4)) (Ehull = 1.0 meV per atom), A1 (NaHfCa(SO4)2(PO4)) ...
