Abstract—Magnetic field shielding at low frequencies is a problem of high importance that is known for a long time. Metamaterials, which are known from fancy applications such as the so-called perfect lens and cloaking, also offer a new way to create efficient magnetic shielding by means of anisotropic metamaterials w…
To enhance the photocatalytic property of coordination polymers (CPs) in the visible light region, Ag loaded coordination polymer composite materials (Ag/CPs) were synthesized successfully through a photoreduction reaction of Ag(+) on the surface of CPs. Photoluminescence (PL) was used to investigate the separation of…

Periodic arrays of compositionally graded Cu–Ni alloy nanopillars (100 or 200 nm in diameter and 450 nm in height) have been fabricated by means of potentiostatic electrodeposition into patterned Au/Ti/Si(111) substrates using a single electrolytic solution. The pillars do not bend after the template removal but remai…
A series of lanthanide sulfates coordination complexes, Ln2(SO4)3(H2O)8 (Ln = Pr (1), Nd (2), Tb (3), Sm (4), Dy (5), Gd (7), Ho (8)), and EuK(SO4)2 (6), were constructed by the reaction in situ of lanthanide ions (Ln3+) with flexible dodecanedioic acid and rigid aromatic 5-sulfosalicylic acid under hydrothermal condi…
The thermal decomposition in thf solution of [H2Ni22Co6C6(CO)36](4-) results in the new [HNi36Co8C8(CO)48](5-) bimetallic Ni-Co octa-carbide, which can be converted into the closely related [H6-nNi36Co8C8(CO)48](n-) (n = 3-6) polyhydrides by means of acid-base reactions. The structure of the [Ni36Co8C8(CO)48](6-) hexa…
Delivery systems that facilitate non-invasive, real-time control of drug release have enormous potential in a wide range of therapeutic applications. This study investigates the potential of a new type of core–shell particle for ultrasound-mediated drug delivery. The capsules were prepared using coaxial electrohydrody…
Here we report a simple bottom-up technology for scalably fabricating gold nanodimple arrays with tunable nanostructures for surface-enhanced Raman scattering (SERS). Double-layer silica colloidal crystal-polymer nanocomposites with an unusual non-close-packed structure created using a spin-coating technique are utili…
The structure and properties of nanocomposite structures based on porous matrix with a triglycine sulfate inclusions have been investigated. Interrelation between the behavior of the dielectric parameters (dielectric susceptibility, the Curie temperature) and structural features of the composite has been established.…
Perovskite-related oxides exhibiting fascinating electric and magnetic properties are important functional materials. We report, for the first time, that pre-perovskite (PP) PbTiO3, characterized by one-dimensional (1D) TiO6 octahedron columns, has a direct-band structure with a gap of 3.20 eV. The faceted single-crys…
We describe a simple and robust technique for fabricating monodisperse Janus hydrogel beads with magnetic anisotropy smaller than the microchannel used to produce them.
Enhancement in coercivity values of precursor powders of cobalt ferrite embedded in silica xerogel as well as polyaniline was observed using vibrating sample magnetometry. We compared the magnetic properties of pure precursor powders of ferrite cobalt prepared by coprecipitation method and those embedded in xerogel an…
Applying high resolution synchrotron-induced photoelectron spectroscopy (SXPS), the electronic properties of a bulk heterojunction (BHJ) model solar cell consisting of phenyl-C61-butyric-acid-methyl-ester (PCBM) as an acceptor and α,ω-dihexylsexithiophene (DH6T) as a donor are investigated. This donor material can be…
Electrochemical and corrosion response of commercially pure aluminum alloyed with binary additions of strontium
Most commercial aluminum alloys, when heat treated in air at 600°C, become activated anodically in chloride solution as a result of segregation of a nanometer size Pb-rich film between the aluminum matrix and thermally-formed γAl 2 O 3 . However, certain recycled alloys, such as AA8006, can be activated at lower annea…
Nanosized Ag3PO4 loaded hydroxyapatite which was prepared by a novel low temperature phosphorization of 3D printed calcium sulfate dihydrate at the nominal silver concentration of 0.001 M and 0.005 M was impregnated by two antibiotics including gentamicin and vancomycin. Phase composition, microstructure, antibiotics…
The Dual Membrane Cell (DM-Cell) is an innovative concept for solid state fuel cells operating in the temperature range 600–700°C. It is based on a junction between the cathode/electrolyte part of a Solid Oxide Fuel Cell (SOFC) and the anode/electrolyte part of a protonic SOFC (PCFC) via a mixed H + and O 2− conductin…
Density functional theory (DFT) calculations using the B3LYP and ωB97XD functionals and Møller-Plesset (MP2) calculations have been used to determine the energy of insertion of seven molecules (CO2, N2, O2, CO, CH4, He and H2O) into two sizes of polyhedral oligomeric silsesquioxane (POSS) cages, T10 and T12. Geometry…
A key factor in determining the economic viability of fusion power is the minimization of the recirculating power required to operate the plant. Neutral beam systems for heating and current drive contribute significantly to this recirculating power. The use of energy recovery is one method of reducing the neutral beam…
1,6-Bis(1-imidazolyl)-2,4-hexadiyne (1) and 1,6-bis(1-benzimidazolyl)-2,4-hexadiyne (5) have been prepared by a novel method that consists in refluxing excess imidazole and benzimidazole with 2,4-hexadiyne-1,6-diol bis(p-toluenesulfonate), pTS (3). This procedure is a viable alternative to the widely used Hay coupling…
