Two novel diarylethene derivatives bearing a rhodamine unit have been successfully synthesized. Their unique multi-addressable switching characteristics as induced by chemical and optical dual inputs stimulation were observed using UV and FL measurements. The two diarylethenes showed excellent photochormism with alter…
Here, we report the synthesis of a graphene film on Cu foil by microwave assisted surface wave plasma chemical vapor deposition (MW-SWP-CVD) at a low pressure and temperature using a hydrocarbon gas. Raman spectroscopy and transmission electron microscopy (TEM) studies clearly show deposited carbon films that consist…
Poly(tetrabutylphosphonium 4-styrenesulfonate) was found to be a unique poly(ionic liquid) showing tunable lower critical solution temperatures in aqueous solution, depending on concentration and ionic strength. As this polymer also exhibits a very high stabilizing power for carbon nanostructures, one can readily synt…
A series of polycrystalline Li3Ba2La3−xEux(MoO4)8 samples were prepared by the conventional solid-state reaction. The phase formation of the samples was investigated by X-ray diffraction measurements. The luminescence spectra and decay curves were studied as a function of Eu3+ concentration and temperature. It turned…
The deactivation mechanism of AuCl3 catalyst in the reaction of acetylene hydrochlorination was studied by using AuCl3 dimer model and the density functional theory (DFT) method. Four possible paths for the acetylene hydrochlorination reaction catalyzed by AuCl3 were illustrated with corresponding transition states. T…
The goal of this paper is to overview radio-frequency (RF) electromagnetic interactions with solid and liquid materials from the macroscale to the nanoscale. The overview is geared toward the general researcher. Because this area of research is vast, this paper concentrates on currently active research areas in the me…
A high performance elastomeric flame retardant nanocomposite was prepared which was based on maleic anhydride grafted ethylene-propylene-diene terpolymer (mEPDM), a one-step synthesised organo-layered double hydroxide (LDH), and an intumescent flame retardant (FR) comprised of pentaerythritol (PER), ammonium polyphosp…
A new type of BaGdF(5):Yb/Er nanoprobe for dual-modal fluorescent and magnetic resonance imaging (MRI) is demonstrated. Water soluble and amine-functionalized BaGdF(5):Yb/Er nanoparticles (NPs) with average size of about 10 nm were synthesized by a facile one-pot hydrothermal method. The in vitro up-converted emission…
The origin of very strong antiferromagnetic exchange in N(2)(3-) bridged complex, [{[(Me(3)Si)(2)N](2)Gd(THF)}(2)(μ-η(2):η(2)-N(2))](-) (1) has been probed using density functional theory (DFT) combined with molecular orbital (MO) and natural bond orbital (NBO) analysis. The analysis helps us to propose a generic mech…
This paper describes a facile one-step approach to prepare superamphiphobic coatings with a coralline-like structure. The coatings were fabricated by spray casting nanocomposites composed of fluorinated multi-walled carbon nanotubes (MWCNTs) and fluorinated polyurethane (PU), in which MWCNTs created both microscale an…
We report a new procedure, exploiting “green” chemistry, resulting in biocompatible magnetically-driven nanocomposites with high antibacterial and antifungal activities against ten tested bacterial strains and four Candida species. The nanocomposites consist of silver nanoparticles (NPs), biogenic magnetite NPs isolat…
We demonstrate hydrothermal synthesis of coral-like CuO nanostructures by selective growth on ZnO nanorods (NRs) at low temperatures. During the hydrothermal processing the resulting hydroxylated and eroded surface of ZnO NRs becomes favorable for the CuO nanostructures growth via oriented attachments. Heterojunction…
A new borazine-linked polymer featuring chlorine-decorated cavities, BLP-10(Cl), has been prepared by the thermal decomposition of benzidine–boron trichloride in toluene under refluxing conditions. BLP-10(Cl) exhibits a moderate Langmuir surface area (1308 m2 g−1) and one of the highest CO2/CH4 selectivities (28.3) by…
Within the past a few years, transformation optics has emerged as a new research area, since it provides a general methodology and design tool for manipulating electromagnetic waves in a prescribed manner. Using transformation optics, researchers have demonstrated a host of striking phenomena and devices; many of whic…
In this paper, we have studied the supramolecular photocatalytic performance of porphyrin-based nanofibers and nanospheres in terms of photodegradation of rhodamine B (RhB) pollutant under visible light irradiation, wherein interesting morphology-dependent photocatalytic activity has been achieved. We have demonstrate…
The incorporation and presentation of cell recognition ligands on the surfaces of biodegradable blood-vessel implants to promote endothelialisation is considered to be a promising approach to prevent platelet aggregation and hence thrombogenesis. In this study, cell-adhesive collagen was covalently immobilised onto po…
In this paper, we highlight some practical aspects in the study of ferroelectric domains in lead-free (K,Na)NbO3 piezoceramics. This work presents and discusses the spatial resolved structure of the ferroelectric domain existing in (K,Na)NbO3 based ceramics studied by confocal Raman microscopy (CRM) coupled with atomi…
The Au(25)(SR)(18)/CeO(2) nanocluster catalyst showed high activity in the homocoupling of aryl iodides (e.g. up to 99.8% yield with iodobenzene) and excellent recyclability.
A novel composite was obtained by hybridizing polypyrrole (PPY) nanotubes with chemically reduced graphene sheets, which comprehensively utilizes the advantages of electric double layer (EDL) capacitor and pseudo-capacitor. Scanning electron microscopy and transmission electron microscopy images revealed that graphene…
Slide-ring (SR) gels are polymer networks with movable cross-links that are prepared by cross-linking polyrotaxane (PR) in which many cyclic molecules are threaded into a linear polymer chain. The elastic modulus E of SR gels shows a unique dependence on cross-linking density: at a high cross-linking density, E decrea…
