Organic photovoltaics (OPVs) are compliant with inexpensive, scalable, and environmentally benign manufacturing technologies. While substantial attention has been focused on optimization of active layer chemistry, morphology, and processing, far less research has been directed to understanding charge transport at the…
The nanogold-modified hemin aptamer and HAuCl4–citrate particle reactions can be monitored by the resonance Rayleigh scattering (RRS) technique. Combining the two reactions, a new and highly sensitive nanocatalytic RRS method was developed to detect 0.2 nmol L−1 hemin.
The new novel material Bi-TiO2/SBA-15 was synthesized by an easy wet impregnation method. A combination of XRD, XPS, Raman, N2adsorption-desorption isotherm measurement, TEM, and solid state UV-Vis spectroscopy has been used to characterize the Bi-TiO2/SBA-15 material. It was found that SBA-15 retained the ordered hex…
A new concept of designing nanocomposite coatings is proposed. The concept consists in microstructural self-organization through simultaneous nucleation of islands of different mutually insoluble or slightly soluble phases at the stage of coating formation. Physical principles on which to select compositions of the co…
The influence of carbon nanostructures of chemical company “Arkema” and ultradisperse metallurgical dust on the properties and structure of gypsum matrix has been studied with the help of mechanical tests, X-ray phase and microstructural analyses. The additives are introduced into the gypsum binder both separately and…
It is shown that the sequence obtained by reducing modulo coefficient and exponent of each Fibonacci polynomials term is periodic. Also if is prime, then sequences of Fibonacci polynomial are compared with Wall numbers of Fibonacci sequences according to modulo . It is found that order of cyclic group generated with m…
Incineration has become a significant treatment method for municipal sewage sludge because of the rising difficulty to find suitable sites for traditional landfill. However, a large amount of sludge incineration ash containing high levels of heavy metals is remained. In order to achieve resource utilization, glass–cer…
The amphiphilic block codendrimer self-assembled into supramolecular vesicles with a bilayer membrane in both hydrophilic and hydrophobic solvents. Surface-modified quantum dots (QDs) were successfully entrapped within the wall of vesicles through a simple self-assembly process without any structural disruption.
The first example of monooxygenation by a high-valent Mn(IV) complex with a peroxide is described. A key Mn(IV) acylperoxo intermediate, which uses m-chloroperoxybenzoic acid as the oxygen donor, is directly observed by electro-spray ionization mass spectrometry and resonance Raman spectroscopy.
A dual-band microstrip patch antenna is designed and analyzed using metamaterial artificial substrate. Metamaterial based substrate is designed using Square Split Ring Resonator (SSRR) and Wire Strip. The antenna is tuned to work at two resonating frequencies in the frequency range from 1 GHz to 4 GHz depending on the…
A novel 3D TiO2 nanomesh with a high specific surface area was successfully synthesized via a simple hydrothermal method using NaOH and P25 as the reactive agents. The as-prepared and calcined 3D TiO2 nanomesh samples were characterized by transmission electron microscopy, scanning electron microscopy and X-ray powder…
When 2-propanol is added to a chloroform solution containing a mixture of CdSe quantum dots (QDs) plus a polystyrene-block-poly(4-vinylpyridine) diblock copolymer (PS404-b-P4VP76, the subscripts refer to the degree of polymerization), the block copolymer assembles into uniform 40 nm diameter spherical micelles with a…
Presented here are two three-dimensional metal–organic frameworks [H2N(CH3)2]2[Cd5(bdt)3(btc)2(H2O)2]·3(H2O) (1) (H2bdt = 1,4-benzeneditetrazol-5-yl; H3btc = 1,3,5-benzenetricarboxylic acid) and [Cd5(Hbdt)2(bdt)(btc)2(H2O)2]·4H2O (2) with integrated topological nets, where the trinuclear cadmium units act as 10-connec…
Molecular dynamics simulation was used to investigate the permeation properties of a virtual condensable vapor through micropores. A permeation model was proposed to simulate the movement of condensable vapor through a micropore. The model is called “micropore filling phase permeation (MFP),” and the effect of feed ga…
In this paper, a simple solution route was developed for the controllable synthesis of coordination polymer Mn2Mo(CN)8·xH2O micro/nano-crystals with unique and multiform morphologies. The syntheses involve the precipitation of Mn2+ and Mo(CN)84− in aqueous solution with polyvinylpyrrolidone (PVP) as a capping agent. B…
The effects of a diamond-like carbon (DLC) coating on a silicon monoxide–graphite composite electrode are studied in order to improve the electrochemical characteristics of silicon monoxide anodes. The DLC is applied through plasma-enhanced chemical vapor deposition and identified by high-resolution transmission elect…
Oriented MIL-110 nanorod arrays on porous anodic aluminum oxide membrane were successfully prepared through a hetero-metal hydroxide nanostrand-assisted growth process in H3BTC aqueous solution. This process provides an environmentally friendly method for synthesis of MIL-110 nanorod arrays without using toxic metal i…
Abstract This paper presents the results of investigations concerning input-output systems of an electromagnetic wave in the visible and near visible spectrum for their application in structures of integrated optics. The input-output structures used in described planar optical waveguides are in a form of prism and gra…
An electrochemiluminescent sensing scheme is presented for remote detection of Hg²⁺ through an ITO-coated nanostructured optical fibre bundle. It is based on the electropolymerisation of CPDT-linked ruthenium phenanthroline complexes carrying azacrown ethers as the receptor units (CPDT = 4H-cyclopenta[2,1-b:3,4-b']dit…
In situ FTIR spectroscopy was employed to investigate some aspects of the ambient temperature (actually, IR-beam temperature) adsorption of acetone on various pure and sulfate-doped zirconia specimens. Acetone uptake yields, on all examined systems and to a variable extent, different types of specific molecular adsorp…
