This report describes the structural and electrochemical properties of the nanocomposite polymer electrolyte (70PEO:30AgI) incorporating SiO 2 filler of different weight percentage (wt %) ranging between 1 and 10 wt %. Studies on inorganic filler in polymer matrix may be quite familiar, but the chosen polymer, the eff…
Two unsymmetric bipyridine-platinum(II)-alkynyl complexes have been synthesised by a post-click reaction. These metal complexes are found to exhibit emission enhancement properties. The photoluminescence quantum yield can be significantly increased from 0.03 in solution to 0.72 in solid-state thin films. Efficient sol…
Novel core-shell quinone-rich poly(dopamine)-magnetic nanoparticles (MNPs) were prepared by using an in situ polymerization method. Catechol groups were oxidized to quinone by using a thermal treatment. MNPs were characterized by using X-ray diffraction, X-ray photoelectron spectroscopy, atomic force microscopy, magne…
To obtain high photovoltaic performances for the emerging copper zinc tin sulfide/selenide (CZTSSe) thin film solar cells, much effort has deservedly been placed on CZTSSe phase purification and CZTSSe grain size enhancement. Another highly crucial but less explored factor for device performance is the elemental const…
Light-triggered treatments in the presence of photosensitizer and oxygen molecule are prevalent for a wide variety of diseases.The reactive oxygen species (ROS), which are produced in the vicinity of malignant tissue by the light activated sensitizers, are considered as active agents in the photodynamic therapy (PDT).…
A novel adsorbent based on Ag-loaded SBA-15 was prepared by a facile wet chemical method for the removal of elemental mercury (Hg0, the most challenging form) for the first time. The adsorbent shows excellent Hg0 removal capacity (>60 μg g−1 at 150 °C) in real flue gas and cyclic performance.
Cell membrane-derived nanoparticles (CNPs) are a novel class of materials and are superior to synthetic nanomaterials in certain aspects due to their biological origin. Although their medical applications have been actively explored, the fundamental structure of CNPs is rarely studied. For example, the membrane orient…
Hausmannite Mn3O4 nanobelts were synthesized from manganese acetate and potassium hydroxide precursors in the presence of melamine–ethanol–distill water via the reflux and solvothermal methods. X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscopes confirm the composition of the as-prepared produ…
We present a detailed experimental and theoretical characterization of the adsorption of the perylene derivative 4,9-diaminoperylene-quinone-3,10-diimine (DPDI) on Cu(111) and compare it to its threefold dehydrogenated derivative 3deh-DPDI, which forms in a surface reaction upon annealing. While DPDI itself does not g…
A small-sized graphene oxide supramolecular assembly was obtained by the inclusion complexation of hyaluronated adamantane with β-cyclodextrin and the π-stacking of graphene oxide with camptothecin, exhibiting an excellent stability in the serum environment and a higher inhibition effect toward malignant cells than a…
Ti-Al-O-N coatings were synthesized by cathodic arc and high power pulsed magnetron sputtering. The chemical composition of the coatings was determined by means of elastic recoil detection analysis and energy dispersive X-ray spectroscopy. The effect of oxygen incorporation on the stress-free lattice parameters and Yo…
Despite a growing interest in graphene nanoplatelets (GNPs)-based metal matrix composites, developing high-performance GNP/metal composites with full exploration of graphene properties remains a great challenge. Here, we propose an effective method to prepare GNP/Cu composites by an electroless plating process and fol…
Caged rhodamine dyes (Rhodamines NN) of five basic colors were synthesized and used as "hidden" markers in subdiffractional and conventional light microscopy. These masked fluorophores with a 2-diazo-1-indanone group can be irreversibly photoactivated, either by irradiation with UV- or violet light (one-photon process…
This paper presents a systematic characterization of electronic states at insulators/(Al)GaN interfaces, particularly focusing on insulator/AlGaN/GaN structures. First, we review important results reported for GaN metal–insulator–semiconductor (MIS) structures. SiO 2 is an attractive material for MIS transistor applic…
A generalized hydrothermal strategy for fabricating three-dimensional (3D) battery electrodes is presented. The hydrothermal growth deposits electrochemically active nanomaterials uniformly throughout the complex 3D mesostructure of the scaffold. Ni inverse opals coated with SnO2 nanoparticles or Co3O4 nanoplatelets,…
A new small molecule of TPA(DPP–PN) 3 was obtained with appending planar phenanthrene units in the molecular terminals, and displayed a maximum PCE of 3.67% in the OSCs.
Cost reduction and improved durability are the two major targets for accelerating the commercialization of polymer electrolyte membrane fuel cells (PEFCs). To achieve these goals, the development of a novel method to fabricate platinum (Pt)-based electrocatalysts with a high mass activity, deposited on durable conduct…
Increased levels of oxidatively damaged DNA have been documented in studies of metal, metal oxide, carbon-based and ceramic engineered nanomaterials (ENMs). In particular, 8-oxo-7,8-dihydroguanine-2'-deoxyguanosine (8-oxodG) is widely assessed as a DNA nucleobase oxidation product, measured by chromatographic assays,…
The chemical, electronic, and structural properties of surfaces are affected by the chemical termination of the surface. Two-step halogenation/alkylation of silicon provides a scalable, wet-chemical method for grafting molecules onto the silicon surface. Unlike other commonly studied wet-chemical methods of surface mo…
TiO2 films have been deposited on ITO substrates by dc reactive magnetron sputtering technique. It has been found that the sputtering pressure is a very important parameter for the structure of the deposited TiO2 films. When the pressure is lower than 1 Pa, the deposited film has a dense structure and shows a preferre…
