The piezoelectric potential output has been studied using a ZnO nanorods (NRs) grown atomic force microscope (AFM) tip in lieu of the normally used AFM tip. The ZnO NRs were synthesised on the AFM tip and on the fluorine‐doped tin oxide (FTO) glass substrate using the aqueous chemical growth method. The as‐grown ZnO N…
Laser brazing with Ti as an active element in silver-copper alloy braze metal has been carried out for binder-less cubic boron nitride and tungsten carbide, using silver-copper- titanium braze alloys with titanium content that varied between 0.28 mass% and 1.68 mass%. Observations of the interface using electron probe…
The stability of quasi-stationary solidification in the presence of a mushy zone is subjected to a nonlinear analysis. The oscillation amplitudes of the fundamental and side harmonics of solidification rate and impurity concentration perturbations are found, and the supercriticality parameter and the average period of…
The influence of thickness and heat treatment on the optical, magnetic and magnetoresistive properties of polycrystalline La0.7Sr0.3MnO3 (LSMO) films deposited onto Al2O3 (012) and Gd3Ga5O12 (111) crystalline substrates was investigated. It was shown that the optical properties of the annealed films are similar in the…
Gelatin–cinnamic acid conjugates (Gel–CAs) with Gel/CA molar ratio of 1:1, 1:3.8, and 1:10.7 were prepared as a UV-absorbing emulsifier. Tensiometric and fluorescence spectroscopic study indicated that Gel–CAs were less surface active than Gel. However, Gel–CAs could act as a potent emulsifier in the preparation of mi…
The far-infrared and submillimeter portions of the electromagnetic spectrum provide a unique view of the astrophysical processes present in the early universe. Our ability to fully explore this rich spectral region has been limited, however, by the size and cost of the cryogenic spectrometers required to carry out suc…
In this paper feedforward controller is designed to eliminate nonlinear hysteresis behaviors of a piezoelectric stack actuator (PSA) driven system. The control design is based on inverse Prandtl-Ishlinskii (P-I) hysteresis model identified using particle swarm optimization (PSO) technique. Based on the identified P-I…
We revisit the well-known and much studied Riesz product representation of the Thue-Morse diffraction measure, which is also the maximal spectral measure for the corresponding dynamical spectrum in the complement of the pure point part. The known scaling relations are summarised, and some new findings are explained. (…
Mathjax On | Off Abstract Combining optics and Fourier transforms is developed further. The Fourier transform property of lenses is introduced to describe coherent and monochromatic image formation.
A simulation program was developed to analyze the influence of temperature profiles of the continuous phase on the polymer properties and monomer conversion in suspension polymerization reactors of vinyl chloride. Polymerization reactions are highly exothermic and the quality of polymer products is really sensitive to…
Background: Electroporation is an electrical technique to deliver different molecules to target tissues. Application of potent electric pulses can increase permeability of the membrane for a number of molecules via creating transient pores in cell membrane. On the other hand, while significant antimicrobial properties…
Abstrak. Modulus geser perlu dijadikan pertimbangan pada produkkayu, khususnya untuk desain yang memiliki rasio tinggi/panjang bentangnya besar.Penelitian ini mendesain 6 tipe panel laminasi kayu Samama (Antocephallus macrophyllus), menganalisis modulus geser dan pengaruhnya terhadap nilai kekakuan (MOEstatis) masing-…
In this study, we investigated localized surface plasmon resonance and the related coupling phenomena with respect to various geometric parameters of Ag nanoparticles, including the size and inter-particle distance. The plasmon resonances of Ag nanoparticles were studied using three-dimensional finite difference time…
In the existent gas practice there absent the recommendations for staged control of pressure drop on a woven filter of gas regulating post, that considerably reduces safety of operation for fixed gas equipment after it. In this work there offered dependencies, allowing to define the value of permissible pressure drop…
Fe(III) ion doped Ni L-Histidine Hydrochloride monohydrate crystals (Fe(III)-NiLHICL) are grown at room temperature using slow evaporation technique. The Fe(III) doped NiLHICL crystals are characterized by spectroscopic techniques such as X-Ray diffraction studies, Electron Paramagnetic Resonance(EPR), Optical Absorpt…
We present the phase space defined by the quantum Hall effect breakdown in polymer gated epitaxial graphene on SiC (SiC/G) as a function of temperature, current, carrier density, and magnetic field. At 2 K, breakdown currents (Ic) almost 2 orders of magnitude greater than in GaAs devices are observed. We use this know…

Nickel oxide (NiO) reduction to Ni during annealing in hydrogen gas (H2) atmosphere is of practical interest for catalytical applications [1] and for production of metallic Ni [2] particles. Recent in-situ TEM study [3] using monitoring of structure changes by EELS indicated that Ni reduction proceeds by Ni nucleation…
Shielding effectiveness of material is an important research topic to meet the requirement of electromagnetic compatibility and prevention of electromagnetic radiation. The paper describes the calculation of SE from surface resistivity. Measurement procedure of shielding effectiveness to the material on flange coaxial…
