The heterostructures of (zinc-blende)–CdTe/(rock-salt)–PbTe are typically found to have their common cubic axes aligned to each other, as in the case of PbTe quantum dots embedded in a CdTe matrix. In this work, we perform both theoretical and experimental studies on the CdTe/PbTe heterostructure in a different geomet…
A simple method to decorate multiwalled carbon nanotubes (MWCNTs) with Ag nanoparticles by using dialdehyde starch (DAS) as complexant and reductant was developed. The Ag–DAS@MWCNTs were characterized by transmission electron microscopy (TEM), fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), a…
A straightforward synthesis of comb-polypeptides of repeated peptide sequences was developed. These polypeptides were obtained by ROP of defined NCA without any post-polymerization grafting. The key to this strategy relies on the preparation of pure NCA bearing a peptide sequence on its side chain, by an original soli…
A versatile molecular device (lanthanide-complex molecular beacon; LCMB) was prepared by tethering ethylenediaminetetraacetic acid to the 5'-end and 1,10-phenanthroline to the 3'-end of stem-loop structured DNA as metal-capturing and sensitizer moieties, respectively. The emission from LCMB responded to the target mol…
A facile method was developed to synthesize a series of Fe-incorporated silica-pillared clays (denoted as Fe-SPCs) with various contents of Fe 2 O 3 . The synthesis was conducted under alkaline conditions using ethanol as the solvent containing the Fe source and dodecyl dimethyl benzyl ammonium chloride as the structu…
Epitaxial thin films of Ru-substituted CoFe2O4 with a cubic spinel structure were fabricated on α-Al2O3 (001) substrates using pulsed laser deposition, and their magnetic and electric properties were investigated. The films showed room temperature ferrimagnetic behavior with hard magnetic features similar to those of…
Abstract Two types of hyperbranched ferrocene‐containing polycarbosilanes were obtained by hydrosilylation of polydiallylmethylsilane (hb‐PDAMS) and polymethyldiundecenylsilane (hb‐PMDUS) with diferrocenylmethylsilane. The redox properties of both polymers have been investigated both in solution and confined onto plat…
The hysteretic properties of metal-ferroelectric-semiconductor (MFS) structures based on Pb(Zr0.2Ti0.8)O3 (PZT) and ZnO films were studied with respect of the quality of the PZT-ZnO interface. The films were grown by pulsed laser deposition (PLD) on platinized silicon (Pt/Si) substrate and on single crystal, (001) ori…
We investigated the substitutional nitrogen center in ZnO single crystals by electron paramagnetic resonance (EPR) and photo-EPR spectroscopy. Aside the three principle hyperfine lines due to the interaction of the N0 (2p5) electron spin with the nitrogen nucleus (I = 1, natural abundance 99.6%), we identify additiona…
A series of 2-phenylbenzoxazole derivatives containing an intramolecular hydrogen-bonded Schiff's base linkage have been synthesised. All are liquid crystalline, displaying only the smectic phase transition, apart from one compound which seems to be non-mesogenic. These compounds may be the first examples reported of…
Without requiring regression for parameter determination, one-dimensional (1D) analytical models are used by many research groups to extract the thermal properties in frequency-domain thermoreflectance measurements. Experimentally, this approach involves heating the sample with a pump laser and probing the temperature…
We fabricated two kinds of sandwiched magnetostrictive/piezoelectric composite and studied their magnetoelectric and electrical impedance properties. It was found that the electrical impedance resonance (fr) and anti-resonance (fanti−r) frequencies were, respectively, corresponded to the converse and direct magnetoele…
Thermal strain, magnetostriction and magnetization measurements of Ni41Co9Mn31.5Ga18.5 polycrystalline ferromagnetic shape memory alloy (FSMA) were performed across the martensitic transition temperature, TM, and the reverse martensitic transition temperature, TR, at atmospheric pressure. When cooling from the austeni…
Nature offers inspiration to new adaptive technologies that allow us to build amazing shapes and structures such as nacre using synthetic materials. Consequently, we have designed a pulsed laser ablation manufacturing process involving thin film deposition and micro-machining to create hard/soft layered “brick-bridge-…
The effect of annealing on melt spun Ni55Mn22Ga23 (at. %) ribbon has been addressed in terms of structural, thermal, thermomagnetic, and magnetic field induced strain (MFIS) behaviour. In comparison to as-spun ribbons, the samples annealed within the L21 domain at 1073 K for 30 h with subsequent furnace cooling, showe…
Using surface-enhanced Raman scattering (SERS) and Fourier transform infrared spectroscopy (FTIR) in the grazing angle incident reflection geometry, new data concerning the abnormal anti-Stokes Raman emission (AASRE) and the molecular orientation of poly( p -phenylenevinylene) (PPV) deposited on metallic supports of A…
Over the past few years, the powder charge-flipping algorithm has proved to be a useful one for structure solution from powder diffraction data, so a semi-systematic study of the effect of the different input parameters on its success has been performed. Two data sets were studied in these tests: a zirconium phosphate…
We solve the Dirac equation, which describes charge massless chiral relativistic carriers in a two-dimensional graphene. We have identified and analysed a novel pseudospin-dependent scattering effect. We compute the tunneling conductance and generalize the analytical result in the presence of the tunable atomic potent…
Conducting polymer materials have demonstrated new possibilities for low-density active material actuators. This article briefly introduces several existing conducting polymer actuator modelling approaches and identifies limitations on their sole applicability for predictive design. The main contribution of this artic…
Using a simple electrochemical depositing process, iron and cobalt‐doped diamond‐like carbon (DLC) films were deposited on Si (100) substrates. The results showed that metallic elements were inhomogeneously doped into highly cross‐linking amorphous carbon matrix, forming the typical nanocrystalline/amorphous nanocompo…
