The cooling condition has a significant effect on the morphology and optical properties of ZnO nanostructures. In this study, four types of nail-shaped nanostructures were prepared by thermal evaporation of Zn powders under different cooling conditions, including natural cooling, vacuum cooling, rapid cooling and vacu…
Sapphire – the single crystal of aluminum oxide (Al2O3) – is one of the most important artificially produced materials. The sapphire fibres studied were grown in Crytur using the “edge-defined film-fed growth” (EFG) technique. Their unique physical and chemical properties can be employed in various applications. Due t…
In this study, heparinized multifunctional mesoporous silica nanoparticles were successfully synthesized and characterized. The new material not only maintains intrinsic functions of bare magnetic and fluorescent mesoporous silica materials such as targeting, imaging, and sustained release of drugs, but also generates…
In this study, the fatigue crack growth rate (FCGR) of a Ti–15V–3Cr–3Al–3Sn (Ti-15-3) alloy, which was aged at a temperature range of 371 to 593°C, was measured in air at room temperature. The specimen aged at 371°C showed clear serrations in the crack growth curve at a stress ratio (R) of 0.1, and it also exhibited a…
Development and fabrication of single‐walled carbon nanotube (SWNT) based pH sensor were reported. The precise alignment of individual SWNT using dielectrophoresis method between the two microgap electrodes was conducted, and the effects of precise alignment of individual SWNT on impedance, long term stability, and ca…
In this mini-review, we report the recent research results in the molecular assemblies composed of nanoscale carbon materials such as fullerenes, carbon nanotubes (CNT) and graphenes for photoinduced electron transfer and light energy conversion. First, we state fullerene-encapsulated porphyrin nanorods for efficient…
An on-line method to detect radial mechanical deforma- tions of power transformer winding turns is presented. First-order perturbation theory is applied to a transformer winding surrounded by the transformer tank wall and the iron core. The transformer wind- ing is modeled as thin conducting cylindrical rings (winding…
The structure, topography and morphology of Pd–C films were studied by AFM (atomic force microscopy), SEM (scanning electron microscopy), Raman and FTIR (Fourier transform infrared spectroscopy) methods. It was found that an increasing content of palladium in films causes a decrease in their roughness and size of nano…
Magnetization hysteresis loops are measured on FeMn/FeCo bilayers. The existence of the exchange bias effect up to room temperature is guaranteed by the presence of copper as a seed layer. We demonstrate that the choice of the growth parameters for Cu allows the control of the magnetic response of the structure, tunin…

This paper presents a study on the mechanical and morphology properties of low density polyethylene (LDPE) blown film modified with crude palm oil (CPO). The effect of the crude palm oil as plasticiser on LDPE matrix has been studied. The LDPE were compounded with 1%, 3% and 5% of crude palm oil in a co-rotating twin…
Graphene is a newly discovered material that possesses unique electronic properties. It is a two-dimensional singlelayered sheet in which the electrons are free and quasi-relativistic. These properties may open a door for many new electronic applications. In this paper we proposed a flat 2-dimensional circular graphen…
The effects of the pre-treatment of commercially available powder by high energy ball milling on the densification of highly refractory ZrB2 were investigated. The pristine powder could be crushed into 10 nm in size by high energy ball milling. The resultant powder was densified, using spark plasma sintering apparatus…
Polyvinyl chloride (PVC) was mixed with natural rubbers which are liquid natural rubber (LNR), liquid epoxidised natural rubber (LENR) and liquid epoxidised natural rubber acrylate (LENRA) for a preparation of a fine nonwoven fiber's mat. PVC and each natural rubbers(PVC:LENR, PVC:LNR and PVC:LENRA) were mixed based o…
A novel intrauterine devices material, polyurethane/nano‐copper (PU/NC) nanocomposite, was prepared. The structure, morphology, copper ion (Cu 2+ ) release rate, and water absorption of PU/NC nanocomposites were investigated. The results indicated that the nanocoppers were uniformly dispersed in the matrix. The releas…
In this study, we examined the ordering of 2D colloidal particle monolayer structures formed atop polyelectrolyte multilayers (PEM) constructed by layer-by-layer deposition. We focused on the interactions between the particles and the substrate surface by changing the top layer of PEMs, along with the fabrication proc…
This paper reports results of a detailed study of the effects of the crystallographic orientation on the performance of the 2–2 parallel-connected composites based on relaxor-ferroelectric single crystals of 0.72Pb(Mg1/3Nb2/3)O3-0.28PbTiO3. These single crystals are poled along one of the following directions in the p…
The final outcome of an impact event (crater size, penetration depth) can be affected greatly by damage accumulation at early stages of the impact event when non-tensile stress states dominate. We have conducted hypervelocity impact experiments on bonded basalt/pyrex specimens utilizing high speed imaging to investiga…
The purpose of this study is to develop a new method for designing compression sportswear from the viewpoint of force by simulation. Applied simulation techniques are 1) skin strain simulation, 2) fabric strain simulation using the anisotropic hyperelastic model, and 3) musculoskeletal simulation. For skin strain simu…
The coalescence process of two gold nanoparticles was observed in situ by High Resolution Transmission Electron Microscopy (HRTEM). The observations reveal that the gold nanoparticles coalesced into one at room temperature. The HRTEM images show the relative rotation of the gold nanoparticles in order to align their c…
