The study of pressure induced phase transition of potassium hydride, which transforms from B1(NaCl) to B2 (CsCl) structure, has been performed using an interaction potential model (IPM) including the role of temperature. Our model consists of long range columbic force, three body interaction forces and short-range ove…
We propose and fabricate a chip containing optical antennas for single molecule Surface-Enhanced Raman Spectroscopy (SMSERS). We verify that SMSERS is achieved using experiments with Rhodamine 6G (R6G) isotopologues.
A two-mask fabrication process of a four-level Fresnel lens was used to evaluate its characteristics through investigating the effect of SU-8 photoresist on the profile of the focusing lens. A two-step deposition of ZnO films was applied to develop a feasible fabrication of a piezoelectric transducer with the structur…
We propose a simple but effective strategy for polarization manipulation holographic lithography by single refractive prism. By tuning the polarization of single laser beam, we simply obtain a pill shape interference pattern where multiple modulated beams are needed in conventional holography lithography. Fabrication…
The force model of gun drill was put forward. It was found that the torque was sensitive to wear and carried the information of the status of wear stage. Moreover, friction between wear pad and work piece was the main source of torque. The experiment applied in studying the correlation between torque and wear has been…
A stable 12-phase AC arc was successfully generated and applied in the field of glass in-flight melting, the arc behavior was characterized by image analysis. The effects of electrode configuration and sheath gas flow rate on arc and melting behavior of granulated glass raw material were investigated. Results show tha…
The stress and strain relationships for polycrystalline materials having tetragonal crystal system with [001] fibre texture, which are required for stress analysis by X-ray diffraction (XRD), were formulated within the framework of the Reuss model of elasticity. In formulating the relationships, two types of orientati…

We discuss the design of a multilayered wavelength selective reflector film using genetic algorithm. The best values of refractive indices and the thicknesses of the layers of the basic unit of the multilayer are determined.
V-doped TiO2 thin films had been fabricated on glass substrates via sol–gel method. These films were characterised by simultaneous thermogravimetry and differential scanning calorimetry (TG-DSC), X-ray diffraction (XRD) and scanning electron microscopy (SEM). It was found that the nanoparticle shape of the TiO2 films…
An original and innovative approach to assess the risks associated to engineered nanoparticles is presented. The primary observations from the literature review are discussed and point out the interdependency of most risk factors. This sole fact justifies the need for an adequate analytical model to ensure a proper ri…
It has been examined to disperse the Au nano-particles directly into liquid by replacing the solid substrate with low-vapor oil in a plasma sputtering apparatus. The dispersing particles in oil is much smaller than the conventional methods. Under low density of particles on oil, the intense absorbance peak is detected…
Considerable research has been carried out in the recent years in the development of models to simulate the inelastic responses of reinforced concrete elements. The enhancement of ductility and the post-peak behaviour are of special interest for the seismic design of structures. Polymer modified fibre concretes are fo…
We utilize narrow Fano-like resonances in gratings composed of metal films that support long range surface plasmons to provide all-optical switching with low input powers. Switching is illustrated for a grating embedded in chalcogenide glass.
A single-beam interference-lithography scheme is demonstrated for the fabrication of large-area slant gratings, which requires exposure of the photoresist thin film spin-coated on a glass plate with polished side-walls to a single laser beam in the ultraviolet and requires small coherence length of the laser. No addit…
Two-color pump-probe microscopy produces chemical contrast between melanins in skin. Increased eumelanin fraction corresponds with worse melanoma prognosis. The spatial heterogeneity of the melanin fraction, both on a cellular and sub-cellular scale, also indicates malignancy.
Mullite can be prepared as lightweight refractories for its low thermal conductivity, advanced volume stability at high temperature environment. Using industrial alumina and nature silica powders as starting materials, the mullite aggregates with microporous structure were synthesized by adding some burning-out materi…
Ultra thin graphene oxide (GO)/polyvinyl alcohol and graphene-polyvinyl alcohol/gelatin composite films were fabricated by electrostatic layer-by-layer assembly and spinning coating methods. The assembling and coating process were traced with UV-visible absorption spectroscopy and the morphology of the formed ultra th…
Back reflections from the end of a parallel-plate metal waveguide can be enhanced up to 99% at a selected frequency by patterning the output facet. This concept can be used to design resonant waveguide structures.
We demonstrate the surface plasmonic wave on the Au thin film can be scattered and manipulated by structured Au nanobumps. Experimental results show the structured gold nanobumps can deflect the surface plasmonic waves to scattering out and focusing.
