【This paper has relatively high technical standard and experimental skill. The fabrication of TCO film with high transparency, low resistance and low chromaticity require exact control of several competing factors. This paper has resolved these problems reasonably well, thus recommended for publication. Indium tin oxi…
Uniform silica nanoparticles were synthesized via Stober method, and fluorescent europium complex with three chelate ligands (i.e. dibenzoylmethane, phenanthroline and acrylic acid) has been prepared. The hydrosoluble silica nanoparticles adsorbed liposoluble europium chelate with strong fluorescence in the aid of ult…
Nickel and antimony doped tin dioxide (NATO) coated titanium electrodes are prepared and tested for electrochemical treatment of pentachlorophenol (PCP). The effect of nickel content on the electrochemical activity is studied using PCP as target organic waste. The nickel content has an optimized value for the activity…
Abstract The research work carried out in our group can be referred to as “Colloid and Interfacial Chemistry”. We subdivide this rather broad research area into four main topics which are covered by the projects presented in this overview. The surfaces we study are surfactant-loaden water-air surfaces, the films are m…
Raman spectroscopy is a powerful tool for rapid mineralogical examination of samples that requires little or no sample preparation. Raman is a very mature technique that is commonly used in laboratory and field investigations across a broad spectrum of targets and applications. As with any technique, however, adapting…

The IR light absorption oscillations in 2D macroporous silicon structures with microporous silicon, SiO2 nanocoatings, and ZnO nanocrystals have been studied at room temperature. Oscillations with giant amplitude are observed in the spectral ranges of absorption by surface levels on "silicon – nanocoating" boundary. T…
The widely used anode for organic light emitting devices (OLED) is ITO/metal/ITO or ITO/insulated layer which could improve the performance of OLED than which only ITO as anode could, while the contribution of such multilayer anode to improve device performance is still poorly understood. A number of mechanisms were p…
As we all know poly(lactic acid), cellulose nanofibrils and poly (ethylene glycol) possess good biocompatibility. Also, PLA/cellulose nanofibrils/PEG ternary composite materials have a good developmental prospect. These composite materials in medical field have a potential application. Nanocomposites of poly(lactic ac…
Abstract Summary: The time relaxation of the optical transmission of polymer‐dispersed liquid crystal films was investigated after application of an electric rectangular pulse. These films, consisting of liquid crystalline microdomains dispersed in a polymer matrix, were obtained by polymerization induced phase separa…
This paper describes an innovative approach to achieve higher capacitance density on silicon interposers than what has been reported with trench capacitors. The approach consists of a novel silicon-compatible low-temperature sinterable metal particulate electrode and a conformal moderate K dielectric to attain the hig…
Substantial progress in the production of hydroxyl-free silica fibers (dry optical fibers) have led to transmission wavelength region from 1.2 to 1.7 µm, thus it is attractive to explore superbroadband luminescence sources for broadband near-infrared (NIR) optical amplifiers, and tunable lasers operating in this entir…
Amorphous silicon-germanium films were prepared by radio frequency plasma enhanced chemical vapor deposition (RF-PECVD) on the glass. The structural characteristics, deposition rate, optical band gap and photosensitivity of the silicon-germanium thin films had been investigated at different substrate temperatures. It…
A new photochromic diarylethene bearing hexatomic ring aryls was synthesized efficiently. Its photochromic properties were examined, it underwent reversible cyclization and cycloreversion reactions upon alternating irradiation with UV and Vis light both in solution and in PMMA film. The fluorescence property of the ph…
The aims of work were theoretical analysis of thermo-optic effects occurring inside Nd:YAG ceramic gain elements and its experimental verification under high heat loads. For theoretical analysis we have applied the semi-analytical models based on thermo-elasticity theory and compared it to results obtained applying CO…
Toward to realizing a novel drug delivery system, a simulation system is considered to be important for a future analysis of it. In this paper, a novel, miniature, and energy-efficient bio-mimetic propulsion concept was proposed. The antibody binding technique is developed and used to attach bacteria to liposome's sur…
A novel composite right/left handed transmission line (CRLH TL) on Si wafer by a green semiconductor integration nanotechnology is presented, designed by calculation, and demonstrated by experiments. First, a coplanar waveguide (CPW) and interdigital capacitance implementation of a CRLH TL is described. A simple circu…
Fourier modal methods, originally developed for modeling diffraction by relief gratings, have recently evolved into efficient tools for full-vector modeling of optical field distribution in high-contrast photonic guided-wave devices. In this paper we discuss mainly 2-D methods, with particular attention to boundary co…
A solvothermal method was used to synthesize functionalized graphene, which exhibits an ultrahigh capacitance. This solvothermal method allows a fine control of the density of functionalities on graphene surface. The structure of resulting functionalized graphene is characterized by X-ray photoelectron spectroscopy (X…
In this paper, HZSM-5 zeolites were modified by aluminium nitrate using the method of impregnation. And the catalytic performances of samples on alkylation of phenol with isopropanol were reviewed. Results show that: after modified with aluminium nitrate, selectivity to o-isopropylphenol was increased and p-isopropylp…
