Motivated by the recent experimental advances in exfoliating Egyptian blue monolayers, we have carried out extensive calculations using density functional theory to understand their geometry, stability, mechanical properties, electronic structures, and magnetism. Upon exfoliation from the bulk, XCuSi4O10 (X = Ca, Sr,…
The electron affinity of carbon is measured on a beam of ${\mathrm{C}}^{\ensuremath{-}}$ by photodetachment microscopy, with a precision increased by one order of magnitude with respect to the last measurement. Isotopes 12 and 13 are used in succession, which makes it possible to determine the isotope shift of the ele…
The design of anti-icing surfaces presents an interface with high causal density that has been challenging to quantify in terms of individual contributions of various interactions and environmental factors. In this commentary, we highlight the role of interfacial water structure as uniquely expressing the physico-chem…
The possibility of heavy hydrocarbons decomposition in the plasma of the creeping glow discharge in a magnetic field is investigated. An electron microscopic analysis of carbon deposit on the electrodes and the walls of the discharge chamber, and gas chromatographic analysis formed in the course of the experiment is c…
Results of experimental studies are presented which examined the effect of electric field on the soot formation in the combustion of hydrocarbon gases. The peculiarity of these experiments is the possibility of obtaining carbon nanostructures - fullerenes in the combustion of hydrocarbons.
LaAlO3/SrTiO3 heterostructures are known to exhibit a sharp, hysteretic metal-insulator transition (MIT) with large enhanced capacitance near depletion. To understand the physical origin of this behavior, the electromechanical response of top-gated LaAlO3/SrTiO3 heterostructures is probed using two simultaneous measur…
The aim of the investigations presented here was to understand how the stiffness of the adhesive affects the failure of ceramic tiles adhered to metallic backings. The working hypothesis was that varying the adhesive stiffness could have the same effect on the ballistic performance as a variation of the adhesive thick…
Water-soluble self-assembled nanostructures were synthesised by simple counter ion exchange of thiacyanine dyes which helps in the formation of nematic (N) and hexagonal (M) chromonic liquid-crystalline (CLCs) phases. Conjugated double bonds as central spacers connected between two benzothiazole segments affect water…
This work reports on the facile preparation of hybrid polymer vesicles with alterable armors of metal nanoparticles by using a novel hyperbranched polymer vesicle as the templates. The vesicles were prepared through the aqueous self-assembly of a hyperbranched multiarm copolymers with many tertiary amino groups on the…
Graphene deposited on various substrates has attracted the attention of the scientific and technical communities for use in a wide range of applications. Graphene on substrates is commonly produced by two types of methods, namely, methods that require a transfer step and transfer-free methods. Compared with methods th…
New research results with regard to two- and three-terminal Si-LEDs realized in a silicon MOS-like device fabricated using the CMOS process technology are presented. Since in the reverse-biased p-n junction the light intensity increases with electric field near the depletion region, the detailed characteristics of the…
The direct growth of single-layer graphene patterns via electron irradiation of aromatic self-assembled monolayers and subsequent annealing is demonstrated. In this way, a reduction in the number of necessary manufacturing steps is achieved. The formed micro- and nanostructures can be arbitrarily shaped and eventually…
Green methods are powerful tools to minimize the use of toxic chemicals which are harmful to human beings as well as environment. The present study focuses on the use of aqueous extract of Callistemon viminalis (bottlebrush) leaves for the synthesis of silver nanoparticles. The extract was used as a bioreductant and t…
Abstract This work determines the size dependent metal nanoparticle (NP) dielectric function from a ‘top-down’ approach using the bulk experimental refractive index as a starting point. Free-electron damping constant ( ) and plasma frequency ( ) parameters in the Drude model are calculated for nickel (Ni), molybdenum…
The complexation of lanthanides (Nd(3+) and Eu(3+)) with glutaroimide-dioxime (H2L), a cyclic imide dioxime ligand that has been found to form stable complexes with actinides (UO2(2+) and NpO2(+)) and transition metal ions (Fe(3+), Cu(2+), etc.), was studied by potentiometry, absorption spectrophotometry, luminescence…
The application of Candida antarctica lipase B in enzyme-catalyzed synthesis of aromatic-aliphatic oligoesters is here reported. The aim of the present study is to systematically investigate the most favorable conditions for the enzyme catalyzed synthesis of aromatic-aliphatic oligomers using commercially available mo…
Abstract Multivalent peptide nanofibers have attracted intense attention as promising platforms, but the fabrication of those nanofibers is mainly dependent on the spontaneous assembly of β‐sheet peptides. Herein we report an alternative approach to the creation of nanofibers: the polyoxometalate‐driven self‐assembly…
The oxidation of CO to CO 2 has been investigated on Pt(997) single-crystal model catalysts with a flow reactor near ambient pressure with X-ray diffraction. Depending on the temperature and gas composition, the surface may consist of monatomic steps separated by 9 atom wide terraces or diatomic steps separated by 18…
An amphiphilic glycopolymer, poly(D-gluconamidoethyl methacrylate -r-3-methacrylamido phenylboronic acid), which could self-assemble to form nanoparticles with a narrow size distribution, was synthesized. Transmission electron microscopy showed that the nanoparticles were spherical in shape with diameters of about 120…
The shape control of Pd nanoparticles is investigated using chloride (Cl(-)) ions as capping agents in an aqueous medium in the temperature range of 60-100 °C. With weakly adsorbing and strongly etching Cl(-) ions, oxygen plays a crucial role in shape control. The experimental factors considered are the concentration…
