Hydrophilic multi-walled carbon nanotubes decorated with magnetite nanoparticles were readily taken up into lymph vessels and delivered gemcitabine to lymph nodes with high efficiency under the guidance of a magnetic field.
Thermally stable, ordered mesoporous CeO2/TiO2 (Ce/Ti molar ratio=0.05) visible-light photocatalysts have been fabricated by the evaporation-induced self-assembly method. Introducing highly dispersed CeO2 species into the mesoporous TiO2 framework can effectively extend the response of TiO2 to the visible-light region…
Current methods of synthesizing single-walled carbon nanotubes (SWNTs) result in racemic mixtures that have impeded the study of left- and right-handed SWNTs. Here we present a method of isolating different SWNT enantiomers using density gradient ultracentrifugation. Enantiomer separation is enabled by the chiral surf…
We report an extensive numerical study of a charged colloidal system with competing short-range depletion attraction and long-range electrostatic repulsion. By analyzing the cluster properties, we identify two distinct regions in the phase diagram: a state composed of stable finite-size clusters, whose relative intera…
Density functional calculations have been performed on a [Gd(iii)Cu(ii)] complex [L(1)CuGd(O(2)CCF(3))(3)(C(2)H(5)OH)(2)] () (where L(1) is N,N'-bis(3-ethoxy-salicylidene)-1,2-diamino-2-methylpropanato) with an aim of assessing a suitable functional within the DFT formalism to understand the mechanism of magnetic coup…
Er 3 + :Ag-antimony glass nanocomposites are synthesized in a new reducing glass (dielectric) matrix K2O–B2O3–Sb2O3 by a single-step melt-quench technique involving selective thermochemical reduction. The UV-vis-near-infrared absorption spectra show typical surface plasmon resonance (SPR) band of Ag0 nanoparticles (NP…
Ratiometric methods of analysis have been developed for the selective determination of lactate or citrate in microlitre samples of human serum, urine or prostate fluids following comparison of anion binding affinities for a family of nine luminescent europium(III) complexes.
Aluminum 7075‐T651 and 7075‐T6 are characterized at quasi‐static and high strain rates to determine Johnson‐Cook (J‐C) strength and fracture model constants. Constitutive model constants are required as input to computer codes to simulate projectile (fragment) impact or similar impact events on structural components m…
Micro-combined heat and power (CHP) holds great potential for lowering energy cost and CO2 emissions in the residential housing sector. Of the various micro-CHP technologies, fuel cells, and in particular solid oxide fuel cells, show great promise due to their high electrical efficiency and resulting low heat-to-power…
The discovery of a new family of high-T(C) materials, the iron arsenides (FeAs), has led to a resurgence of interest in superconductivity. Several important traits of these materials are now apparent: for example, layers of iron tetrahedrally coordinated by arsenic are crucial structural ingredients. It is also now we…
Excellent area-specific-resistance (ASR) values have been exhibited by cathode materials with a Sr-doped layer perovskite type structure and therefore show themselves to be possible candidates for intermediate-temperature-operating solid oxide fuel cell (IT-SOFC, 600–800°C) applications. (SBSCO) electrode was sintered…
A facile one-pot microwave irradiation reduction route has been developed for the synthesis of highly luminescent CdTe quantum dots using Na 2 TeO 3 as the Te source in an aqueous environment. The synthesis parameters of this simple and rapid approach, including the reaction temperature and time, the pH of the reactio…
Supercapacitors have emerged as attractive energy storage devices for systems requiring rapid charge-discharge cycles and high power densities. Progress in conducting polymer research for this application has shown tremendous promise due to the polymers' tendency to form highly porous films and exhibit reversible redo…
A simple trinuclear dysprosium complex shows complex slow relaxation of the magnetisation.
This tutorial review gives a brief introduction to impedance spectroscopy and discusses how it has been used to provide insight into charge transport through conducting polymers, particularly when the polymers are used as electrodes for solution studies or the design of electrodes for biomedical applications. As such…
A simple but elegant way to obtain linked donor-acceptor entities involving metallomacrocycle complexes with fixed distance and orientation is the use of coordination of axial ligands to metallomacrocycle complexes. A series of electron acceptor-bearing silicon phthalocyanine (SiPc) triads have been readily synthesize…
The development and use of functional tissue-engineered products is currently limited by the challenge of incorporating microvasculature. To this end, we have investigated strategies to facilitate vascularization in scaffold materials, in this case poly(ethylene glycol) (PEG) hydrogels. These hydrogels are hydrophilic…
Super-hydrophilicity and super-hydrophobicity are fundamentally opposite properties of special wettability, which are governed by surface chemical composition and surface roughness. Smart responsive surfaces switching reversibly between super-hydrophobicity and super-hydrophilicity can be effectively fabricated by mod…
Experimental studies of thin-film Nb- and Ta-doped TiO2 have reported that doped anatase is highly conductive, yet doped rutile is semiconducting. Standard DFT functionals (LDA, GGA) predict that for doped anatase TiO2 the excess charge occupies the bottom of the conduction band, and is delocalised over all the Ti ato…
Pulsed spray evaporation chemical vapor deposition (PSE-CVD) was employed for the synthesis of cobalt-based spinel oxide thin films, Co(3-x)Fe(x)O4 with x = 0-1.56. XRD, Raman scattering and FTIR emission spectroscopy show that the normal spinel structure was retained for 0 < or = x < or = 0.65 by the selective insert…
