Following the targeted word direction of Opto- and Nanoelectronics, the field of science and technology related to the development of new display technology and organic materials based on liquid crystals ones is meeting the task of replacing volume inorganic electro-optical matrices and devices. An important way in th…
We explore non-local effects in radially symmetric heat transport in silicon thin layers and in graphene sheets. In contrast to one-dimensional perturbations, which may be well described by means of the Fourier law with a suitable effective thermal conductivity, two-dimensional radial situations may exhibit a more com…
In this Letter, governing equations for the nanoscale plates with consideration of both surface effects and non-local elasticity are derived. The closed-form solutions for the critical buckling force of simply supported plates are obtained. Results show that the critical buckling force of the nanoplate increases with…
The rotation of the carboxylate groups in DOTA (DOTA = 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetate) complexes of several lanthanide ions and Sc(3+) was investigated with density functional theory (DFT) calculations and with variable temperature (17)O NMR studies at 4.7-18.8 T. The data obtained show that the…
Methods for the synthesis of styrylazines and styrylbenzazines are considered, their photophysical and photochemical properties are analyzed. The review covers both published data and own works of the authors. Important data on the prospects of application of arylhetarylethenes as components of electroluminescence mat…
Herein, we have shown a large-scale cell-mimetic (cytomimetic) aggregation process by using cell-sized polymer vesicles as the building blocks and intervesicular host-guest molecular recognition interactions as the driving force. We first prepared the hyperbranched polymer vesicles named branched polymersomes (BPs) ar…
Strahlend weiß: Hybrid-Halbleitermaterialien auf der Basis periodischer nanostrukturierter ZnS-Schichten emittieren helles weißes Licht. Ihre Emissionsintensität, Quanteneffizienz und Farbqualität kann systematisch über die Zusammensetzung der anorganischen wie der organischen Komponente eingestellt werden. Diese Mate…
Abstract The rapid growth and commercialization of nanotechnology are currently outpacing health and safety recommendations for engineered nanomaterials. As the production and use of nanomaterials increase, so does the possibility that there will be exposure of workers and the public to these materials. This review pr…
Porous silica microspheres were fabricated by a facile surface-protected etching strategy. Polyvinylpyrrolidone (PVP) was used as a protecting polymer absorbed on the surface of silica microspheres and NaOH was employed as an etching agent. Owing to the protective action of PVP and inhomogeneous etching, mesopores wer…
A one-pot reactions of cobalt powder with iron(II) chloride in dimethylformamide (DMF; 1) or dimethyl sulfoxide (DMSO; 2) solutions of polydentate salicylaldimine Schiff base ligands (H(2)L(1), 1; H(4)L(2), 2) based on 2-aminobenzyl alcohol (1) or tris(hydroxymethyl)aminomethane (2), formed in situ, yielded two novel…
This work reports on the experimental investigation of wide band gap compounds LiMgZ (Z = P, As, Sb), which are promising candidates for opto-electronics and anode materials for lithium batteries. The compounds crystallize in the cubic (C1(b)) MgAgAs structure (space group F (4) over bar 3m). The polycrystalline sampl…
It's hip not to be square: The oxidation of elemental palladium with SO3 leads to Pd(S2O7) in which the Pd2+ is in an octahedral coordination environment of oxygen atoms (see structure Pd red, O blue, S yellow) and not the usual square-planar environment for Pd2+ species. This unexpected geometry leads to the observed…
Using near-infrared fluorescence videomicroscopy with spectrally selective excitation and imaging, more than 400 individual (10,2) single-walled carbon nanotubes (SWCNTs) have been studied in unsorted liquid dispersions. For each nanotube, the spatially integrated emission intensity was measured under controlled excit…
In this article, we introduce fully digital selective ZnO nanowire array growth on inkjet-printed seed patterning. Through proper natural convection suppression during hydrothermal growth, successful ZnO nanowire local growth can be achieved. Without any need for photolithographic processing or stamp preparation, the…
A novel salicylideneaniline type fluorescent organogelator based on a 3,4,5-(tri-dodecyloxy)benzoyl group immobilizes aromatic solvents. The resulting gels show enhancement in emission and thermochromic/non-photochromic behaviour during sol-to-gel transition.
We report our investigation on the low temperature scaling behavior of niobium-doped barium stannate. Electrical properties of the system BaSn${}_{1\ensuremath{-}x}$Nb${}_{x}$O${}_{3}$ (with $x$ = 0.001, 0.005, 0.010, 0.050, and 0.100), prepared by the solid-state route, were studied employing impedance spectroscopy i…
The orientation of hexagonal boron nitride ( BN ) nanosheets was controlled in polymer‐based nanocomposite film using microscopic molds while applying a dc electric field. The hexagonal BN nanosheets were dispersed by sonication in a prepolymer mixture of polysiloxane followed by high speed mixing. The homogeneous sus…
The most unusual feature in the surface-enhanced Raman scattering (SERS) of 4-aminobenzenethiol (4-ABT) is the appearance of b 2 -type bands in the region of 1100–1500 cm –1, which, in recent years, has given rise to a dispute over their origin. In order to resolve this dispute, we have examined the SERS spectral patt…
Automated diffraction tomography was used to collect electron-diffraction data for solving the crystal structure of ECS-3, which is the first example of a crystalline hybrid organic–inorganic aluminosilicate with open porosity, generated by a regular arrangement of phenylene rings interconnecting aluminosilicate layer…
First-principle calculations of the structural, electronic, vibrational and mechanical properties of the primitive-centered tetragonal boron nitride (pct-BN) structure are performed. Results reveal that pct-BN is more energetically favorable than h-BN above the pressure of 8.8 GPa and dynamically stable at up to 120 G…
