The anisotropic nanocrystalline magnets were produced by hot pressing and die-upsetting the mixed powders of MQU-F and MQU-G with a mass ratio of x:1−x (x = 0−1). With x increasing from 0 to 1, the intrinsic coercivity (Hci) decreased from 22.7 to 15.0 kOe, and the remanence (Br) and maximum energy product ((BH)max) a…
Heat capacities of liquids and liquid-quenched glasses (LQGs) of dicyclorohexylmethanol (DCHM) and tricyclohexylmethanol (TCHM) were measured by adiabatic calorimetry. Upon cooling the liquid compounds, they undergo glass transitions around 250 and 265 K, respectively. Temperature dependence of the FT-IR spectrum of T…
Abstract Microwave magnetoelectric (ME) effects over 8–25 GHz have been studied in bilayers of single crystal Y‐type hexagonal ferrite Ba 2 Zn 2 Fe 12 O 22 and polycrystalline lead zirconate titanate (PZT) or single crystal lead magnesium niobate–lead titanate (PMN–PT). The bilayers are made by epoxy bonding or eutect…
The antioxidant effects of sesamol films were evaluated using a food simulant (linoleic acid) and a real food (oat cereal). Sesamol was melt blended with high density polyethylene, linear low density polyethylene and ethylene‐vinyl acetate resins using co‐extrusion to produce sesamol films of multilayer structure; for…
Yali pears (Pyrus bretschneideri Rehd.) are susceptible to mechanical damage. In this study, the protective effects of chitosan treatments on the quality of bruised pears were evaluated. The fruit were treated with 1.5% chitosan before or after bruise damage, respectively. Then, the fruit were stored at 16 °C and 85-9…
This paper presents an electrical insulator pollution estimation technique based on the ultrasonic noise emitted by these insulators when connected to energized electrodes. The spectral subband centroid energy vectors (SSCEV) algorithm was employed in the signal processing. This algorithm can be understood as being a…
The efficiency of the treatments involving CNS disorders is commonly diminished by the toxicity, reduced stability and lack of targeting of the administered neuroactive compounds. In this study, we have successfully multifunctionalized CMCht/PAMAM dendrimer nanoparticles by coupling the CD11b antibody and loading MP i…
This study elucidates the underlying mechanism associated with microstructural modifications responsible for significant enhancement of wear resistance of tool steels by deep cryogenic treatment (DCT). It is demonstrated that DCT not only reduces the amount of retained austenite, but also conditions the martensite tha…
Abstract This work describes the plasma‐enhanced chemical vapor deposition of thin films at atmospheric pressure using dielectric barrier discharges fed with argon, oxygen and different methyldisiloxanes, i.e., hexamethyldisiloxane, pentamethyldisiloxane, and 1,1,3,3‐tetramethyldisiloxane. The influence of the methyld…
The supporting substrate plays a crucial role in preserving the superb electrical characteristicsof an atomically thin 2D carbon system. We explore carrier transport behavior in achemical-vapor-deposition- (CVD-) assembled graphene monolayer on hexagonal boron nitride (h-BN) substrate. Graphene-channel field-effect tr…
The electrical storage mechanism in GeSbTe phase change materials is discussed in terms of their gap states using GeTe as a model system. The lowest energy defect in crystalline rhombohedral GeTe phase is the Ge vacancy, because it reconstructs along the resonant bonding directions. The lowest energy in amorphous GeTe…
Gold nanoparticles are generally considered to be biologically inactive. However, in this study we show that the addition of 1.4 nm diameter gold nanoparticle induces the remodeling of the ring-shaped protein TRAP into a hollow, capsid-like configuration. This structural remodeling is dependent upon the presence of cy…
The bacteria Enterobacter sp. and Bacillus anthracis (avirulent strain) were isolated from a lathe workshop and industrial waste water, respectively. The ability of both isolates to synthesize lead nanoparticles was studied. The relationship between the amount of polysaccharides secreted and metal deposited was demons…
This paper describes the synthesis of Ba-doped PbZn 1/3 Nb 2/3 O 3 -PbMg 1/3 Nb 2/3 O 3 -PbNi 1/3 Nb 2/3 O 3 -PbTiO 3 multicomponent solid solutions rich in PbNi 1/3 Nb 2/3 O 3 , which include ferroelectric relaxors, ferroelectrics with a diffuse phase transition, and classic ferroelectrics, and presents the phase dia…
We report on the dependence of the converse magnetoelectric effect (CME) on the composition of Co60Fe20B20, Co43Fe43B14 and Co28Fe52B20 soft magnetic layers when coupled with PZT-micro-fiber-composites (MFC). In all cases we show strong CME responses, with squareness reduction of 60−80% when increasing the E-field fro…
Abstract With its exceptional charge transport properties, graphene has emerged as a potential replacement material in the electronics industry. For these applications, much effort has been devoted towards the synthesis of large defect‐free graphene sheets. However, recent developments have enabled the efficient produ…
The cis- and trans-azobenzenes are known as photochromic isomers with the trans- converting into the cis-form and vice versa upon irradiation with specific wavelengths. We have quantum chemically investigated the cis- and trans-forms of substituted azobenzene diradicals, with two nitronyl nitroxides, imino nitoxides,…
When a continuum approach is considered for textile reinforcements, the internal loads are described by a stress tensor. The mechanical behaviour of the textile material is very much dependent on the fiber directions, and the frames defined from warp and weft directions are preferred to write the stress components. Th…
Tensile and microstructural properties of multiwall carbon nanotube (MWCNT)/polyisoprene (PI) composites have been investigated after cross-linking achieved purely by simultaneous high-pressure high-temperature treatment. The method enables gradual increase of the cross-link density without interference of vulcanizati…
Ein H-Brücken-gebundener ionischer Cokristall mit Imidazol als molekularem Rotator und L-Weinsäure als homochiraler Komponente erweist sich als displazives ferroelektrisches Material, das bei 252 K eine Phasenumwandlung von paraelektrisch nach ferroelektrisch durchläuft (siehe Bild). Das außergewöhnliche dielektrische…
