Controlling Chiral Self-Sorting in Truxene-Based Self-Assembled Cages

open access: yesInorganics, 2022
Coordination driven self-assembly of achiral components, i.e., hexa-alkylated truxene ligands (L) with bis-metallic complexes (M2), afforded three chiral face-rotating stereoisomer polyhedra (M6L2). By tuning the length of the alkyl chains as well as the

Carbamylation of elastic fibers is a molecular substratum of aortic stiffness

open access: yesScientific Reports, 2021
Because of their long lifespan, matrix proteins of the vascular wall, such as elastin, are subjected to molecular aging characterized by non-enzymatic post-translational modifications, like carbamylation which results from the binding of cyanate (mainly ...

Products of random matrices. [PDF]

open access: yesPhysical review. E, Statistical, nonlinear, and soft matter physics, 2002
We derive analytic expressions for infinite products of random 2 x 2 matrices. The determinant of the target matrix is log-normally distributed, whereas the remainder is a surprisingly complicated function of a parameter characterizing the norm of the ...

Quantum spin-Hall effect and topologically invariant Chern numbers. [PDF]

open access: yesPhysical Review Letters, 2006
We present a topological description of the quantum spin-Hall effect (QSHE) in a two-dimensional electron system on a honeycomb lattice with both intrinsic and Rashba spin-orbit couplings.

Human pluripotent stem cells in contemporary medicine

open access: yesИсследования и практика в медицине, 2015
Human pluripotent stem cells (hPSCs) are capable of indefinite proliferation and can be differentiated into any cell type of the human body. Therefore, they are a promising source of cells for treatment of numerous degenerative diseases and injuries ...
