Maghemite (γ‐Fe2O3)‐poly(methyl methacrylate) (PMMA) nanocomposites were prepared by grafting 3‐(trimethoxy‐silyl) propyl methacrylate on the surface of maghemite nanoparticles, this process being followed by methyl methacrylate radical polymerization. Three different hybrids with 0.1, 0.5, and 2.5 wt% of maghemite na…
AIM: Oral and intramuscular sustained-release antiretroviral solid drug nanoparticles (SDNs) are in development but there is limited understanding of whether nanoparticles or dissolved drug predominate systemically. MATERIALS & METHODS: A flow cytometric method was developed to analyze SDNs in biological fluids such a…
Single crystals of LaMn0.5Co0.5O3 belonging to the ferromagnetic-insulator and distorted perovskite class were grown using a four-mirror optical float zone furnace. The as-grown crystal crystallizes into an orthorhombic Pbnm structure. The spatially resolved 2D Raman scan reveals a strain-induced distribution of trans…
Cholesteryl group-modified tilapia gelatins (Chol-T-Gltns) with various Chol contents from 3 to 69 mol % per amino group of Gltn were prepared for the assembly of liposomes and cells. Liposomes were physically crosslinked by anchoring Chol groups of Chol-T-Gltns into lipid membranes. The resulting liposome gels were e…
Polystyrene spheres are used to template TiO2 with a single layer of 300 nm wells which are infilled with PbS quantum dots to form a heterojunction solar cell. The porous well device has an efficiency of 5.7% while the simple planar junction is limited to 3.2%. Using a combination of optical absorption and photocurren…
In the present work, ZnO nanoparticles (ZNP) and ZNP in combination with nanoclays are reported as reinforcing agents for the preparation of ‘Green’ nanocomposites based on glutaraldehyde (GA) crosslinked starch/jute fabric. A solution-induced intercalation method has been used for the successful fabrication of the na…
Electrical treeing is an electrical aging phenomenon that severely threatens the operation safety of power equipment, in which polymer is used as primary insulation material. A type of low-density polyethylene-montmorillonite (LDPE/MMT) nanocomposite was prepared using melt method to study the impact of MMT nanopartic…
High purity Ti3SiC2 samples were prepared by infiltration sintering method. The tribological behaviours of high pure bulk Ti3SiC2 dry sliding against a GCr15 bearing steel disc were experimentally investigated on a pin on disc type tester under different sliding speeds from 5 to 50 m s−1, different electric currents f…
The results of previous work (Baldwin et al 2013 J. Nucl. Mater. 438 S967–70 and Baldwin et al 2014 Nucl. Fusion 54 073005 ) are extended to explore the influence of layer thickness on the thermal D 2 release from co-deposited Be–(0.05)D layers produced at ∼323 K. Bake desorption of layers of thickness 0.2–0.7 µ m are…
A [2.2]paracyclophane-based through-space conjugated oligomer comprising three π-electron systems was designed and synthesized. The arrangement of three π-conjugated systems in an appropriate order according to the energy band gap resulted in efficient unidirectional photoexcited energy transfer by the Förster mechani…
Metal nanoparticles have attracted considerable attention owing to their unusual physical and chemical properties from those of their molecular and bulkcounterparts and are fundamental to surface science applications such as catalysts, optics, photonics, sensors, and spectroscopy. Traditionally, the opticalabsorption…
The introduction of robust redox groups at the periphery of common amine-terminated dendrimers is of interest in the design of dendritic nanobatteries, sensors, and redox catalysts. Here we are applying the recently discovered uncatalyzed hydroamination of ethynylcobalticenium, a mild "green" reaction that quantitativ…
The homogeneous dispersion of fine graphite nanoplatelets throughout the epoxy matrix with different mass fraction is prepared. Influence of graphite nanoplatelets of varied mass fraction in the mechanical reinforcement and shape memory effect of graphite nanoplatelets/epoxy composite is investigated. The morphology a…
In this work, the influence of the substrate temperature (Ts) on the chemical composition of propanethiol plasma polymers was investigated for a given set of plasma conditions. In a first study, a decrease in the atomic sulfur content (at. %S) with the deposition time (td) was observed. This behavior is explained by t…
The orthovanadate ${\mathrm{DyVO}}_{3}$ crystal, known to exhibit multiple structural, spin-, and orbital-ordering transitions, is presently investigated on the basis of magnetization, heat capacity, resistivity, dielectric, and polarization measurements. Our main result is experimental evidence for the existence of m…
A series of Ni0·5−xZn0·3−xMn0·2+2xFe2O4 ferrites was successfully prepared by the sol–gel autocombustion method. The structure and electromagnetic properties of the powders were characterised by X-ray diffraction, SEM and vector network analysis. The pure powders were formed by heating at 1200°C for 3 h in air, and gr…
We control the pretilt angle of liquid crystals (LCs) by simultaneously doping silica nanoparticles (SNs) and reactive monomers into the LC cell. Application of AC high voltage (ACHV) to the cell compels the lifting force and the facilitation of polar groups to move the SNs and monomers toward the substrate surface. P…
This paper develops a magnetoelectric (ME) heterostructure FeCuNbSiB/Ni/Rosen-type piezoelectric transformer (RPT)/Ni/FeCuNbSiB consisting of a RPT Pb(Zr1-xTix)O3with its drive-end sandwiched between two graded-magnetostrictive layers of FeCuNbSiB/Ni. The graded-magnetostrictive layer FeCuNbSiB/Ni is made up of Fe-bas…
We propose an ansatz for the wave function of a non-interacting quantum particle in a deterministic quasicrystalline potential. It is applicable to both continuous and discrete models and includes Sutherland's hierarchical wave function as a special case. The ansatz is parameterized by a first cohomology class of the…
Optical properties of hexagonal multiferroic oxides $R\mathrm{Mn}{\mathrm{O}}_{3}$, where $R=\mathrm{Ho}$, Er, Tm, Yb, and Lu, have been studied in the far-infrared spectral range between 100 and 2000 cm${}^{\ensuremath{-}1}$ and temperatures between 1.5 and 300 K by means of several experimental techniques: Mueller m…
