Except for well-known predictions for the island of stability at Z=126 recently it was found that a similar kind of the stability region can be expected at Z=110-112. The half-life time estimation – an example of a biotic factor is Abstract: The existence of long lived superheavy nuclei (SHN) is controlled mainly by spontaneous fission and $alpha$-decay processes. According to microscopic nuclear theory, spherical shell effects at Z=114, 120, 126 and N=184 provide the extra stability to such SHN to …
Furthermore, the half-life of 2b was also found to be highly solvent dependent (Table 1, entries 2, 8–11). One obvious reason for the lower stability in CDCl 3 could be the presence of trace amounts of acid in the used CDCl 3 .
Over the last several years, data sharing has been increasingly required by funders, associations, and academic institutions in an effort to improve transparency and the ability of other scientists to reproduce, and build upon, published research.
Background: 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU), a commercial chemotherapeutic drug for treating malignant brain tumors, has poor thermal stability and a short half-life. Immobilization of BCNU on a nanocarrier might increase the thermal stability of BCNU and extend its half-life.

This high-level accumulation of GsiB can at least partially be attributed to the remarkably long half-life (∼20 min) of the gsiB mRNA. Analysis of different gsiB – lacZ fusions revealed that this stability is not determined by sequences at the 3 ′ end of the transcript but rather by sequences upstream of the translational start codon.
The half-life of nuclides is plotted as a function of proton (Z) and neutron (N) number. The continent of stable elements ends at the lead–bismuth cape, and a region of relative stability appears around the isotopes of thorium and uranium ( Z = 90 , 92 ).

While the stability increases significantly with the increase of generation pressure for foams without any additive, it, however, changes weakly with the change in generation pressure for foams with polymer additives. Consistent with the previously reported studies, it is found that the foam stability (drainage half-life) increases, primarily due to the decrease of bubble size, at higher
