In this paper, the general laws of localized plastic flow development are described for linear work hardening stages nineteen metals. The correlations established and discussed between their element position in periodic table elements parameters autowave process these elements. Patterns considered metals from 3rd, 4th, 5th, 6th periods A conditional characteristic plasticity is introduced its r...
Metallodrugs offer potential for unique mechanisms of drug action based on the choice of the metal, its oxidation state, the types and number of coordinated ligands and the coordination geometry. We discuss recent progress in identifying new target sites and elucidating the mechanisms of action of anti-cancer, anti-bacterial, anti-viral, anti-parasitic, anti-inflammatory, and anti-neurodegenera...
The ground states of the mixed 3d-metal dimers TiV, TiCr, TiMn, TiFe, TiCo, TiNi, TiCu, TiZn, VCr, VMn, VFe, VCo, VNi, VCu, VZn, CrMn, CrFe, CrCo, CrNi, CrCu, CrZn, MnFe, MnCo, MnNi, MnCu, MnZn, FeCo, FeNi, FeCu, FeZn, CoNi, CoCu, CoZn, NiCu, NiZn, and CuZn along with their singly negatively and positively charged ions are assigned based on the results of computations using density functional t...
Coiled coils are protein structure domains with two or more alpha-helices packed together via interlacing of side chains known as knob-into-hole packing. We analysed and classified a large set of coiled-coil structures using a combination of automated and manual methods. This led to a systematic classification that we termed a "periodic table of coiled coils," which we have made available at ht...
Figure 1: Periodic table in 1D. numbers of electrons have significant dipole moments and are thus reactive species [1]. Alternatively, atoms with even numbers of electrons are inert and do not have any dipole moment due to their symmetry. Based on these results, we have built the 1D version of the Mendeleev’s periodic table which only consists of two groups: alkali metals and noble gases, as sh...
Boron is the fifth element in the periodic table of elements and has a number of important functions. The borate minerals have been known for thousands of years and have varied history from the deserts of Tibet to the alchemists of the middle ages. Boron occurs in most foods produced from plants. Since 1989 its nutritional value has been debated. Boron plays several biochemical roles in animals...
