Magnetic nanoparticles (mNPs) ranging from the nanometre and micrometre scale have been widely applied in recent years in the area of biomedicine. They contain unique magnetic properties and due to their size can function at a cellular level, making them attractive candidates for cell labelling, imaging, tracking and…
In this review article, new systems being investigated for application in solid oxide fuel cells are discussed. For the electrode materials, materials with the perovskite or related structures continue to dominate the field, due to the need for high electronic conductivity. Research in this field is being directed tow…
Metal copper mesh with superhydrophobic and superoleophilic surface had been successfully fabricated via a facile solution-immersion process. The hierarchical structure was prepared on the commercial copper mesh surface by etching with the nitric acid. After being modified by 1-hexadecanethiol (HDT), the as-prepared m…
This review summarizes recent advances in synthesis routes for quickly and reliably making and functionalizing magnetic nanoparticles for applications in biomedicine. We put special emphasis on describing synthetic strategies that result in the production of nanosized materials with well-defined physical and crystallo…
Cellulose is the most abundant biorenewable and biodegradable resource on the earth. However, the extent of its application is limited due to its inefficient dissolution in solvents. Thus, the development of new cellulose solvents continues to be an active area of investigation. In this work, a series of ionic liquids…
In pursuit of efficient quantum dot (QD)-sensitized solar cells based on mesoporous TiO(2) photoanodes, a new procedure for preparing selenide (Se(2-)) was developed and used for depositing CdSe QDs in situ over TiO(2) mesopores by the successive ionic layer adsorption and reaction (SILAR) process in ethanol. The size…
Elucidating the impact of nanoparticle size and shape on biological systems is of fundamental importance to nanotoxicology and biomedicine. Currently, the ability to determine this is limited by the lack of a model nanoparticle system having a narrow size and shape distribution over the relevant size range (2-200 nm).…
Here for the first time, we demonstrate novel nanodome solar cells, which have periodic nanoscale modulation for all layers from the bottom substrate, through the active absorber to the top transparent contact. These devices combine many nanophotonic effects to both efficiently reduce reflection and enhance absorption…
A simple aqueous solution route has been developed for the preparation of luminescent carbogenic dots from carbohydrates. The optical properties of the carbogenic dots can be tuned by differing the starting materials or the duration of nitric acid treatment. The multicolor emission capability and potential nontoxic na…
A progress report is presented on a selection of scientific, technological and commercial advances in the biomedical applications of magnetic nanoparticles since 2003. Particular attention is paid to (i) magnetic actuation for in vitro non-viral transfection and tissue engineering and in vivo drug delivery and gene th…
Gyrotropic, magnetically-hard hexaferrite materials, are very promising candidates to operate as quasi-optical nonreciprocal devices at high frequencies (> 90GHz), with the consequent advantage of obviating the need for requiring extra biasing magnets and avoiding low temperature demagnetization. In this paper, a T…
Abstract The reaction of copper(II) acetate with the tetradentate Schiff base like ligand H 4 L {( E , E )‐[{diethyl 2,2′‐[4,5‐dihydroxy‐1,2‐phenylenebis(iminomethylidyne)]bis(3‐oxobutanoate)}] leads to the formation of the square planar N 2 O 2 coordinated complex [H 2 CuL]. Reaction of two equivalents of this comple…
Abstract The transformation of low‐density amorphous (LDA) ice produced from high‐density amorphous (HDA) ice was studied up to 400 MPa as a function of temperature by in situ Raman spectroscopy and optical microscopy. Changes in these amorphous states of H 2 O were directly tracked without using emulsions to just abo…
We report on a novel optical thin film material, erbium-doped deuterated amorphous carbon, fabricated directly on silicon substrate at room-temperature via controlled thermal evaporation of a Metal-Organic compound in a Plasma-Enhanced Chemical Vapour Deposition (MO-PECVD) system. High erbium concentrations (up to 2.3…
Abstract Chlorosulfonated polyethylene (CSPE)/organomontmorillonite (OMMT) nanocomposites were prepared by a melt intercalation method. The microstructure of the nanocomposites was characterized by transmission electron microscopy and X‐ray diffraction. The effects of the OMMT content on the mechanical properties and…
Abstract Diacrylate compounds derived from α‐pinene and limonene (TDAs: TDA‐1 and TDA‐2) were photocured with methacryl‐substituted polysilsesquioxane (ME‐PSQ) prepared from 3‐(trimethoxysilyl)propyl methacrylate and tetramethylammonium hydroxide (TMAOH) in the TDA/ME‐PSQ weight ratio of 20 : 0, 20 : 1, 20 : 2, 20 : 3…
In this paper, we present a study of the structural and self-assembling properties of a new family of bolaamphiphiles. These bolaamphiphiles are unsymmetrical, having one sugar polar head at one side and one glycine betaine polar head at the other side. The variations that we introduced concern the length of the main…
Abstract The submicrostructure of dynamically fatigued unfilled natural rubber vulcanizates was investigated by using scanning electron microscope (SEM) and atomic force microscope (AFM). AFM photographs showed the sample surface roughness became worse after tensile fatigue and the largest surface undulation was as tw…
Abstract In this study a procedure for the preparation of compatibilized nanoclays was used to produce effective nanocomposites based on unsatured polyester (UP) resin. A compatibilization procedure of the filler with a selected surfactant has been developed and optimized, the effect of organic modifiers on the synthe…
Abstract The spectra of 2,5‐dihydroxybenzoic acid (DHBA) have been recorded using Fourier transform‐infrared spectroscopy (FT‐IR) and FT‐Raman measurements. The total energy calculations of DHBA were evaluated for various possible conformers. The spectra were interpreted with the help of normal coordinate analysis bas…
