The anisotropic superconducting properties of the LaRu 2 P 2 single crystal have been systematically investigated by magnetic and transport measurements. Both the upper critical field ( H c2 ) and the lower critical field ( H c1 ) show isotropic behavior, indicating the three-dimensional nature of its Fermi surface to…
The dynamics of bulk toluene and toluene confined in the 1,2-O-(1-ethylpropylidene)-α-D-glucofuranose gel was studied using (1)H field-cycling nuclear magnetic resonance relaxometry. The proton spin-lattice relaxation time T(1) was measured as a function of the magnetic field strength and temperature. The observed dis…
The reactions of NiSO 4 ·6H 2 O or Mn(CH 3 COO) 2 ·4H 2 O with the planar ligands of indane-1,2,3-trione trioxime (H 3 Itto) or indane-1,2,3-trione-1,2-dioxime (H 2 Itdo) gave two planar pentanuclear clusters [Et 3 NH] 2 [Ni 5 (HItto) 4 (MeOH) 2 (H 2 O) 6 (SO 4 ) 2 ]·2H 2 O ( 1 ) and [Ni 5 (HItdo) 2 (Itdo) 2 (DMF) 4 (…
Nanoparticles of iron boride (Fe2B, Fe2B coated in SiO2, FexCo2−xB coated in SiO2) were synthesized using the reduction of metal ions by sodium borohydride. X-ray diffraction confirms the amorphicity of the coated compounds and scanning electron microscope imaging revealed the nanoparticulated structure of all compoun…
Abstract A series of novel phosphorus‐containing polyesterimides were prepared from diols—a mixture of a new aromatic phosphorus‐containing bisphenol, namely 1,4‐bis[ N ‐(4‐hydroxyphenyl)phthalimidyl‐5‐carboxylate]‐2‐(6‐oxido‐6H‐dibenz<c,e><1,2>oxaphosphorin‐6‐yl)‐naphtalene, with aliphatic diols such as 1…
Dopants are non-native atoms commonly used to modify the properties of bulk semiconductors. In this paper we demonstrate that by controlling the addition of cobalt(II) to growing zinc oxide nanocrystals (ZnO NCs) it is possible to modulate the resulting properties. We show that the environment of cobalt may be control…
Various hybrid functionals (B3LYP, B97-2, PBE0, BMK, BH&HLYP, CAM-B3LYP, and LC-ωPBE) implemented in density functional theory were applied to give estimate of static first hyperpolarizabilty (β(0)) of (E)-benzaldehyde phenylhydrazone designated as (E)-BPH. Against those of MP2 computations as a function of the underl…
Manufacturing of leucite glass-ceramics often leads to materials with inhomogeneous microstructures. Crystal-glass thermal mismatches which produce microcracking around larger crystals-agglomerates are associated with reduced mechanical properties. The hypotheses were that fine (< 1 µm) crystal size and uniform micros…
The transport of liquid droplets on surfaces carrying reactants offers advantages in the creation of fluidic devices crucial for life science applications. In a majority of situations, a selection of these droplets on a surface, rather than all of them, will need to be moved at any one time. It is a formidable challen…
Biocompatible surfaces: Cationic, anionic, and neutral nanoparticles (NPs) were immobilized via dithiocarbamate formation onto polyethylenimine (PEI) films to create biofouling resistant surfaces. These surfaces are designed to bind proteins without denaturation, hence preventing biofouling. Extended incubation of the…
We study the evolution of orbital patterns in ferromagnetic layered ruthenates due to the competition of Coulomb interactions, compressive $c$ axis and orthorhombic distortions in the presence of a polarizing orbital field coupled to the angular momentum. By means of the exact diagonalization on a $2\ifmmode\times\els…
Abstract Nonmodified multiwalled carbon nanotubes (MWCNTs)/sulfonated polyoxadiazole (sPOD) nanocomposites are successfully prepared by a facile solution route. The pristine MWCNTs are dispersed in a sPOD solution, and the mixtures are fabricated into thin films by solution casting. The homogeneous dispersion of nanot…
To reveal dynamical property of a guest ion in type-I clathrate compound, $n$- and $p$-type clathrates ${\text{Ba}}_{8}{\text{Ga}}_{16}{\text{Ge}}_{30}$ have been investigated by Raman scattering. It is found that the guest ion in a 6d-site cage (6d-cage) rotationally moves for both $n$- and $p$-type since the additio…
A series of novel long-chain hyperbranched poly(ethylene glycol)s (LHPEGs) with biodegradable connections were designed and synthesized in one pot through proton-transfer polymerization using PEG and commercial glycidyl methacrylate as monomers and potassium hydride as catalyst. The LHPEGs were hydrolyzed at neutral p…
Abstract Solubilization of reduced graphene is simply attempted through in situ reduction of graphene oxide (GO) solution in the presence of poly(propylene imine) dendrimers G4 or G5 with terminal amine groups through noncovalent interaction. Interestingly, porous graphene film was formed by filtration of these dendri…
We demonstrate that the electronic spectrum of graphene in a one-dimensional periodic potential will develop a Landau level spectrum when the potential magnitude varies slowly in space. The effect is related to extra Dirac points generated by the potential whose positions are sensitive to its magnitude. We exploit a c…
Dispersion of ultranarrow PbS nanorods of 1.8 nm diameter, encapsulated by a fluidlike soft trioctylamine layer, in the nematic liquid crystal (LC ZLI-4792) results in a novel soft matter type blend with enhanced electro-optic properties. Despite having a cubic rock-salt structure, the ultranarrow rods possess a finit…
Based on in situ scanning probe microscopy/spectroscopy, this study investigates the stabilization of Zn-terminated ZnO polar plane using surface defects. O-terminated surface defects on a nanometer scale, which have two morphologies, i.e., hexagonal cavities and small pits, are observed at the submonolayer depth on t…
Abstract Massive quantities of marine seaweed, Ulva armoricana are washed onto shores of many European countries and accumulates as waste. Attempts were made to utilize this renewable resource in hybrid composites by blending the algal biomass with biodegradable polymers such as poly(hydroxy‐butyrate) and poly‐(ε‐capr…
A novel wide-field approach for the real-time Surface Enhanced Raman Scattering (SERS) imaging of multiple silver nanoparticle clusters suspended in solution is described. This method enables direct correlation of the SERS activity of a single nanoparticle aggregate and its size through measurement of the cluster diff…
