In this study we have investigated the suitability of a number of different mesoporous silica nanoparticle structures for carrying a drug cargo. We have fully characterized the nanoparticles in terms of their physical parameters; size, surface area, internal pore size and structure. These data are all required if we a…
Diluted magnetic semiconductors Zn 1− x Fe x O nanoparticles with different doping concentration ( x = 0, 0.01, 0.05, 0.10, and 0.20) were successfully synthesized by hydrothermal method. The crystal structure, morphology, and optical and magnetic properties of the samples were characterized by X‐ray diffraction (XRD)…
First-principles studies of the thermodynamics and transport of intrinsic point defects provide guidelines for defect-controlled synthesis and shed light on the electronic and ionic conduction mechanisms in LiCoO 2 and LiNiO 2 .
Alkoxide-intercalated CoFe–LDHs have been successfully synthesized and characterized, showing size-dependent magnetism, supercapacitive properties and excellent water oxidation electrocatalytic behaviour.
The thermoelectric properties, including ZT , of stoichiometric and reduced phases of the orthorhombic perovskite CaMnO 3 were evaluated using DFT.
A novel synthesis of dextran coated bismuth–iron oxide nanoparticles (BION) is reported. They are found to be effective as contrast agents for both CT and MRI and to be both biodegradable and biocompatible.
RAFT-mediated polymerisation-induced self-assembly (PISA) is used to prepare six types of amphiphilic block copolymer nanoparticles which were subsequently evaluated as putative Pickering emulsifiers for the stabilisation of n-dodecane-in-water emulsions. It was found that linear poly(glycerol monomethacrylate)-poly(2…
The purpose of the present work is to demonstrate that the hexagonal Yb/Er:NaGdF4 core size has a great impact on the completeness of the NaYF4 shell covering the core. With the increase of core size, the morphology of core-shell nanocrystals evolves from nanosphere to hexagonal nanoprism and finally to hexagonal nano…
The influence of tetrabutylammonium hydroxide on the phase composition (cubic zinc blende versus hexagonal wurtzite) of ZnS nanoparticles was studied. The ZnS nanoparticles were prepared by a microwave-assisted solvothermal method, and the phase structure and optical properties along with the growth process of ZnS nan…
Reduced graphene oxide (RGO) has been employed as an electrode for a series of vertically structured photodetectors. Compared with mechanically exfoliated or chemical vapor deposited graphene, RGO possesses more oxygen containing groups and defects, which are proved to be favorable to enhance the performance of photod…
A novel approach for optimization of the thermoelectric properties of p-type Heusler compounds with a C1b structure was investigated. A successful recipe for achieving intrinsic phase separation in the n-type material based on the TiNiSn system is isoelectronic partial substitution of Ti with its heavier homologues Zr…
Amorphous cellulose and xylan structures were analyzed using high-resolution 2D-NMR, and the NMR data were obtained in a DMSO- d 6 /pyridine- d 5 (4 : 1) solvent system.
We perform a comprehensive first-principles study of the electronic properties of van der Waals (vdW) trilayers via intercalating a two-dimensional (2D) monolayer (ML = BN, MoSe2, WS2, or WSe2) between a MoS2 bilayer to form various MoS2/ML/MoS2 sandwich trilayers. We find that the BN monolayer is the most effective s…
It is well recognized that calcium carbonates (CaCO3) is one of the main components of scale that is commonly encountered in chemical and related industries. The calcium carbonate scale often grows extensively on equipment and parts, causing major operational difficulties. This paper presents experiments on calcium ca…
Superparamagnetic iron oxide nanoparticles (SPIONs) conjugated with recombinant human epidermal growth factor (SPION-EGF) were studied as a potential agent for magnetic resonance imaging contrast enhancement of malignant brain tumors. Synthesized conjugates were characterized by transmission electron microscopy, dynam…
(19)F NMR spectroscopy has been used to study the local environments of anions in supercapacitor electrodes and to quantify changes in the populations of adsorbed species during charging. In the absence of an applied potential, anionic species adsorbed within carbon micropores (in-pore) are distinguished from those in…
A novel approach was applied to synthesize silver nanoparticles using starch under sonication. Colloidal silver nanoparticles solution exhibited an increase of absorption from 420 to 440 nm with increase starch quantity. Transmission electron microscopy followed by selected area electron diffraction pattern analysis i…
Understanding the nature of the self-assembly of peptide nanostructures at the molecular level is critical for rational design of functional bio-nanomaterials. Recent experimental studies have shown that triphenylalanine(FFF)-based peptides can self-assemble into solid plate-like nanostructures and nanospheres, which…
Metal oxide nano-microstructures are applied in photocatalytic surfaces, sensors or biomedical engineering, proving the versatile utilization of nanotechnology. However, more complex or interconnected nano-microstructures are still seldomly met in practical applications, although they are of higher interest, due to en…
The utilization of microsecond dwell times allows for the detection of multiple elements within a single particle.
