Poly-Systemic Analysis of Military Students’ Discipline

open access: yesОбразование и наука, 2018
Introduction. The concept of “discipline” has not been thoroughly investigated in psychology yet. In addition, a system of military higher education needs for new psychological knowledge on discipline structure and its formation.The aim of the research ...

Using the Photostationary State of Arylazopyrazoles to Control Phase Transitions of Liquid Crystals

open access: yesAdvanced Functional Materials, EarlyView.
A series of new arylazopyrazole photoswitches is designed as dopants for liquid crystalline materials. Unprecedented, the distribution of photoisomers at the photostationary state upon irradiation with light of specific wavelengths (365, 460, 520 nm) is used to control the liquid crystalline phase transitions under isothermal conditions, including ...

Solid state physicochemical properties and applications of organic and metallo-organic fullerene derivatives [PDF]

open access: yes, 2016
We review the fundamental properties and main applications of organic derivatives and complexes of fullerenes in the solid-state form. We address in particular the structural properties, in terms of crystal structure, polymorphism, orientational ...

Engineering Relative Spatial Structure of Dual Atomic Sites with Asymmetric Coordination for High‐Performance Hydrogen Evolution Activity

open access: yesAdvanced Functional Materials, EarlyView.
Dual‐atom catalysts featuring varying spatial configurations of metal sites (Pt1Fe1 DACs) are employed to systematically investigate the influence of spatial arrangements on the electronic structure and catalytic activity of active sites. Notably, the 3D asymmetric Pt1Fe1‐TAC dimer, featuring strong interatomic interactions, demonstrates superior ...

Nuclear Tetrahedral Symmetry

open access: yes, 2003
We recall the main features of the Td (tetrahedral) symmetry in atomic nuclei and present realistic mean-field calculations supporting the existence such a symmetry all over the nuclear chart.

Aza[6]helicene Platinum Complexes: Chirality Control of cis-trans Isomerism [PDF]

open access: yes, 2014
International audienceIt was serendipitously observed that cis-[PtCl2(NCEt)PPh3] reacted differently with either racemic or enantiopure 4-aza[6]helicene, giving respectively cis (racemic) and trans (enantiopure) [(PtCl2)-Cl-II(4-aza[6]helicene)PPh3 ...

Enhanced Nitric Oxide Electroreduction to Ammonia via Modulating Spin‐Polarization of Fe Single‐Atom Catalysts

open access: yesAdvanced Functional Materials, EarlyView.
A strategic spin‐polarization suppression in Fe single‐atom catalysts is proposed to enhance electrocatalytic reduction of NO to NH3. Employing a top‐down electrospinning strategy, self‐supported FeSAC with Fe‐N3S1 coordination structure and spin‐state transition is engineered from high‐spin to low‐spin.

A novel DNAH11 variant segregating in a sibship with heterotaxy and implications for genetic counseling

open access: yesMolecular Genetics & Genomic Medicine, 2020
Background Isomerism or heterotaxy syndrome is the loss of normal asymmetry of the internal thoraco‐abdominal organs in the left‐right axis and is associated with cardiovascular malformations.
