17.2). In an effort to reach a stable state, the unstable atoms in these radioactive particles radiate energy. Some particles radiate energy for millions of years with slow radiation, while some do so in a very short time but with intense radiation. Because of the longevity of the nuclear ...
This was quite unexpected as this molecule is highly unstable at ambient conditions26. Its synthesis requires the use of high-energy radiation or strong acids and the resulting compound can only be isolated under high vacuum or in argon matrix and at very low temperatures27,28. Indeed, the ...
Amine-functionalized adsorbents offer substantial potential for CO2 capture owing to their selectivity and diverse application scenarios. However, their effectiveness is hindered by low efficiency and unstable cyclic performance. Here we introduce an amine-support system designed to achieve efficient and stab...
Appendix IV: Masses in Atomic Mass Units for Neutral Atoms of Stable Nuclides and a Few Unstable NuclidesB.C. . Only with the experiment of Torricelli in 1644, however, did it become possible to distinguish questions of empty space clearly from implications of air pressure. The natural ...
In principle, the reaction of IaH with a given A could proceed by an initial ET,(Equation 3)N-DMBI-H + A → N-DMBI-H⋅+ + A⋅−followed by further reaction of IaH⋅+ (clearly unstable from the irreversible cyclic voltammogram of IaH29) to form Ia+. E0/⋅−(A) values ...
Figure S4 shows that the states in O atoms of DIT are highly unstable near the Fermi level before adsorbing Li2S6. After the adsorption of Li2S6, the interaction between O and Li atoms leads to a downward shift of the energy levels and stabilizes the system [42]. Furthermore, the ...
High-valent iron ( þ 4, þ 5, þ 6) compounds are not formed spontaneously at ambient conditions, and the ones obtained synthetically appear to be unstable in polar organic solvents, especially aqueous solutions, and this is what limits their studies and use. Here we describe ...
(forSchNet) in our re-implementations. We find, thatSO3kratesenables reliable MD simulations and high accuracies without sacrificing computational performance. Gray shaded area indicates the regime of sub-millisecond step time.cMD step time vs. the number of atoms in the system. The smaller pre...
Despite their high solvent levels, these compositions typically performed poorly and tended to be unstable at lower temperatures, i.e., at about 40° F. (about 4° C.) to about 65° F. (about 18° C.), thickening, solidifying, or forming precipitates or gels. However, recently, ...
As used herein, the term “substituted aliphatic” refers to an alkane possessing less than 10 carbons where at least one of the aliphatic hydrogen atoms has been replaced by a halogen, an amino, a hydroxy, a nitro, a thio, a ketone, an aldehyde, an ester, an amide, a lower aliphatic...
