In the framework of continuum thermodynamics a new approach to phase transition and separation phenomena is developed by emphasizing their nonlocal character. The phase-field is regarded as an internal variable and the kinetic or evolution equation is viewed as a constitutive equation of rate type. The second law of t…
Bacterial cellulose has long been manufactured and used for industrial purposes and health. Bacterial cellulose more profitable than the cellulose plants because during the manufacturing process, they do not harm the environment. The purpose of this study was to identify differences of cellulose produced by Acetobacte…
Collagen and cyclodextrins are well known as triple helical protein and oligosaccharides. Cyclodextrins are the simplest organic compounds, which exhibit complex formation with other organic molecules and hence are excellent models of enzymes. This property of cyclodextrins to form inclusion complexes is being exploit…
In the present work, nano scaled zero valent silver were synthesized from the plant extract of Vitis vinifera under atmospheric conditions through green synthesis. A systematic characterization of silver nanoparticles was performed using UV, SEM,TEM and antimicrobial studies. The diameter of silver nanoparticles was p…
Unsatisfactory corrosion resistance is one of the major disadvantages of magnesium alloys that impede their wide application. Microstructural changes, especially grain sizes, of Mg alloys have significant influence on their corrosion resistance. Cryogenic machining was reported to effectively induce grain refinement o…
Abstract: In this work, The adsorption of methane onto multi-walled carbon nanotubes (MWCNTs) was studied, in which the influences of temperatureand pressure were investigated. The physical properties of the MWCNT were systematically characterised by Scanning Electron Microscopy (SEM) and Brunauere-Emmette-Teller (BET…
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…
