The original theoretical model of polyelectrolyte adsorption onto water-dispersed colloid particles is extended to the system of polydisperse droplets of sunflower oil. Polycation (poly(allylamine hydrochloride)) and polyanion (poly(sodium 4-styrenesulfonate)) are taken in the theoretically projected concentrations to…
A facile and effective method to synthesize dendrite-shaped calcium carbonate (CaCO3) nanocrystals in aqueous solutions of dodecyltrimethylammonium bromide (DTAB) and β-cyclodextrin (β-CD) is reported. It has been demonstrated that the supramolecular host–guest complexes formed by DTAB and β-CD play a key role in the…
In order to know how much iron loss of an actual stator core increase in each manufacturing process, we are developing the magnetic property evaluation method of a rotating machine. In this research, we prepared two kinds of specimens, including piled up five punched electrical steel sheets that are the shape of the a…
Abstract Zn(OH)F microbesoms have been synthesized on a large scale by a facile solution‐based method using polymer as crystal growth modifier. The obtained products were characterized by X‐ray powder diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). The effects of modi…
A cylindrical wave expansion method is used to obtain the scattering fleld for a two dimensional cylindrical invisibility cloak incorporating perfect electromagnetic conductor (PEMC) at perturbed void region. A near-ideal model of the invisibility cloak is set up to solve the boundary-value problem at the inner bounda…
We report the synthesis, structures and magnetic properties of a series of chromium(III) metal-centered triangle (or "star") clusters, [Cr(4){RC(CH(2)O)(3)}(2)(4,4'-R'(2)-bipy)(3)Cl(6)] [R = Et, R' = H (2); R = HOCH(2), R' = H (3); R = Et, R' = (t)Bu (4)], prepared by two-step solvothermal reactions starting from [CrC…
Single-walled carbon nanotubes (SWNTs) have been used successfully to fabricate highly transparent and flexible field emission displays (FEDs). Field emission measurements indicated that SWNTs films have great potential to work as building blocks for next generation transparent and flexible FEDs.
We have developed a centrifugal heating apparatus to fabricate layered TiS2-based thermoelectric elements, and evaluated their thermoelectric properties. We found that layered (SnS)1.2(TiS2)2 bulk elements with preferred crystallographic orientation can be produced within a quartz tube under a centrifugal acceleration…
Liesegang rings, periodical bands or ring patterns formed by inorganic precipitation in polymer gel medium, have attracted lots of interest of researchers aiming to construct ordered structures. Inspired by the Liesegang ring phenomena, chitosan, instead of inorganic species, was used as building block to construct a…
A novel and simple approach for fabricating polymeric nanofibers has been established, and gelatin nanofibers have been successfully fabricated. Specifically, gelatin aqueous solution was evenly dispersed in ethyl acetate solution of cellulose acetate butyrate (CAB) to form an immiscible polymer solution blend, and th…
Binding to colloidal structures such as gold nanoparticles (Aunps) is known to affect protein conformation, potentially altering the function and bioinvasiveness of the biopolymer. As the use of protein–Aunp constructs is widespread and increasing, an improved understanding of the invasiveness of nanomaterials is of f…
In a present paper results of the process of synthesis and study of a perovskite-type solid solution of the chemical composition (1-x)BiFeO 3 -xBaTiO 3 for x=0.3 are reported. Synthesis of 0.7BiFeO 3 -0.3BaTiO 3 (BF-BT) ceramics was carried out according to the solid-phase reaction from the mixture of powders. Simulta…

In this work, ZnO microrod arrays were successfully synthesized on a curved sphere surface through thermal evaporation of a mixture of ZnS and Zn powders and using Zn foil as the substrate. Results indicated the as-grown ZnO microrod has a smooth top with an average diameter of 500 nm and a length of 1 μm. The formati…
A highly luminescent compound, stilbene-2,4-dimethyl-6-(1,2,2,4-tetramethyl-1,2-dihydroquinolin-6-yl)-1,3,5-s-triazine (MQT), exhibits solvent polarity-induced emission enhancement. A fluorescent sensor array was fabricated with MQT and porous polymer substrates. The colorimetric changes of the array exposed to VOCs c…
High level waste (HLW) originating from aqueous reprocessing of fast reactor fuels consists mainly of fission products, minor actinides and noble metals which are higher in concentration compared to that from thermal reactors. Borosilicate glass may not be an efficient matrix to fix this waste. Similarly, chloride HLW…
The Center for Aircraft Structural Life Extension (CAStLE) at the United States Air Force (USAF) Academy has undertaken work to produce a standardized test method for determining the effect of a corrosion inhibitor containing chromate on small scale fatigue damage. CAStLE is specifically focusing their research on the…
Patterned biohybrid films show great potential for application in biosensing, bioconversion, and biochips. Their preparation generally involves a multistep procedure including patterned film fabrication and biomolecule immobilization. Here, we report a one-step approach to well-ordered protein-containing films by the…
It is well known that the supramolecular assembly of block copolymers with associated low-molecular-weight additives leads to rich phase behaviors in both bulk and thin films. In this study, we demonstrate that the supramolecular assembly is also an efficient approach to control the microdomain orientation in block co…
