We report NPI as a flexible dielectric for transistors based on 2D atomic sheets such as graphene and MoS2, which features high mechanical flexibility, stable electrical performances and low roughness. NPI offers the realistic prospects for highly flexible electronics beyond the typical 2% limitation of high-κ or cera…
Growth of monolayer single-crystalline graphene using low pressure chemical vapor deposition (LPCVD) method is reported. Radio frequency (RF) nano switches based on coplanar waveguide double-clamped single-crystalline graphene membrane was achieved for the first time. Owing to the single crystalline nature, its life t…
In order to reduce the costs associated with Poly-β-hydroxybutyrate production, growth and Poly-β-hydroxybutyrate production of Ralstonia eutropha were studied in batch culture on different carbon sources. Experiments were designed and conducted to not only lower the cost of Poly-β-hydroxybutyrate production by using…
The first nitroxide‐mediated polymerization of butyl acrylate/methyl methacrylate and/or styrene diblock copolymers‐based nanoclay composites is reported. Polybutyl acrylate (PBA) macroinitiators synthesized in the presence of raw and modified clays are used for chain extension. All materials are characterized by prot…
Transformers have been one of the greatest inventions in the electrical industry. It helps in transferring energy between two or more circuits through electromagnetic induction. Single phase transformers find applications in domestic appliances because of its simplicity and less cost. They can be used as voltage regul…
In this paper the impact of thermal and electrical aging on AC and impulse breakdown strength of oil-impregnated paper was investigated. Sheets of paper were thermally aged at 140 °C for 30 days. A comparison between AC and impulse breakdown strength of unaged paper layers, 10, 20 and 30 days thermally aged paper was…
We investigated the absorption and luminescence spectra and the low-frequency spectra of dielectric losses of the nematic liquid crystal (NLC) suspensions with quantum dots (QDs) CdSe/ZnS with a core diameter of 3.5 nm and 5.0 nm. The changing of luminescence intensity and dielectric losses in the region below 10<sup>…
We propose a kinetic model to characterize the image sticking phenomenon under nonuniform electric field in fringe field switching (FFS) LCDs by taking material properties and device parameters into account. This model agrees well with the experimental results. We investigate the voltage and temperature effects of ima…
In this study, the hole‐electron balance of quantum dot lightemitting diodes (QDLED) was tuned in order to achieve efficiency enhancement. This hole‐electron balance optimization was realized by inserting thin barrier layer in the electron transportation layer. Although the current density was slightly sacrificed beca…
We report a polymer‐stabilized blue‐phase liquid crystal (PS‐BPLC) cured with a visible laser in an in‐plane‐switching (IPS) cell. Its electro‐optic properties are compared with those of a conventional PS‐BPLC cured by ultraviolet (UV) light. Besides, a PS‐BPLC grating is fabricated using visible‐laser holography
From the analysis of experimental X-ray absorption spectra and the calculation of atomic multiplets it is found that the grinding of powder manganites La 0.5 Ca 0.5 MnO 3 and Nd 0.5 Sr 0.5 MnO 3 in a vibration mill results in the formation of nanocrystallites and a partial transformation of trivalent manganese ions in…
The electrospinning technique was used to fabricate 1D nanofibers of Zinc Oxide (ZnO). Polyvinylpyrrolidone (PVP) ̸ zinc acetate Nano fibers electrospun using solution containing PVP dissolved in ethanol and zinc acetate in distilled water were mixed, followed by calcination at 500°C for 3hours to remove the polymer.…

Experimental results on the creation of fine-grained aluminum alloys with different scale structural components, ranging from tens of microns to tens of nanometers, by various external influences in the liquid and solid states were present.It is found that complex processing of the melt, including its heating to a tem…
(Sr 0.95 Gd 0.05 )TiO 3 (SGTO) ceramics are successfully prepared via spark plasma sintering (SPS) respectively at 1548, 1648, and 1748 K by using submicron-sized SGTO powders synthesized from a sol–gel method. The densities, microstructures, and thermoelectric properties of the SGTO ceramics are studied. Though the S…
A uniform lying helix liquid crystal device with a large flexoelastic coefficient, fast flexoelectric switching and operating at a room temperature is presented. We describe a liquid crystal (LC) mixture for flexoelecro‐optic LC mode made from constituents with smaller and larger flexoelectric coefficients with differ…
<p>O tungstato de bário (BaWO<sub>4</sub>) é um importante material cerâmico da família das <italic>scheelitas</italic>que apresenta aplicações em dispositivos fotoluminescentes como cintiladores, diodos emissores de luz, lasers do estado sólido, entre outros, destacando-se como matriz ho…
The study of immune cell migration is important for understanding the immune system network, which is associated with the response to foreign cells. Neutrophils act against foreign cells before any other immune cell, and they must be able to change shape and squeeze through narrow spaces in the extracellular matrix (E…
A polymer-inorganic nanocomposite of fibrous Na-Mg triple chain hydrosilicate and polyamidoimide based on 4-chloroformyl-( N - p -chloroformylphenyl)phthalimide and 4,4′-diaminodiphenyl ether has been developed. Morphology and dynamic mechanical properties of the nanocomposite films have been studied. Anisotropy of me…
