This article presents a facile and generally applicable methodology for the morphology diversification of two-dimensional (2D) nanostructure arrays by modifying angle-resolved heterogeneous shadow mask (AR-HSM). Colloid spheres are used to prepare scalable well-organized monolayer film by self-assembly method and then…
The development of biomaterial has reached biodegradable stage. Biodegradable means it can be degraded after certain period of time after implantation and cause no harm for the system. Degradable Biomaterial has the potential to be used as Coronary Stent to minimize the risk from thrombosis issue. Thrombosis is a symp…
Abstract P2‐type NaxM O2 (M = Mn and Co) is a promising cathode material for low‐cost sodium ion secondary batteries. In this structure, there are two different crystallographic Nai (i = 1 and 2) sites with different Coulomb potential $ (\varphi _i)$ provided by M4–x and O2–. Here, we experimentally determine a differ…
In this paper, the physical characteristics and memristive behavior of TiO2 nanostructures grown at different substrate positioning by wet chemical solution were investigated. TiO2 thin film as a seed layer for TiO2 nanostructures growth was first deposited on ITO-coated substrate by RF magnetron sputtering method. Ti…
The approach for patterning 15-nm half-pitch (HP) structures using extreme ultraviolet lithography combined with self-aligned double patterning is discussed. A stack composed of a double hard mask, which allows decoupling photoresist transfer and trim, and an α-Si mandrel, which offers better mechanical properties dur…
Severe plastic deformation (SPD) using various pass number of Equal Channel Angular Pressing (ECAP) experiment and followed heating at 400°C has been done for rod brass Cu-Zn 70/30 to investigate the operation on microstructure and hardness of the alloy. Optical microscopy and SEM are used to examine the microstructur…
Modern medicinal diagnosis strongly relies on imaging techniques. Supramolecular chemistry can help radiologists by enhancing images that are acquired with the help of exogenous contrast agents. Most targeting functions such as peptides, saccharides, antibodies etc. bind to their receptors via non-covalent interaction…
Soya spent powder as an inexpensive and renewable source has been used as a filler for linear-low density polyethylene (LLDPE) in this study. Linear-low density polyethylene (LLDPE)/soya spent powder composites were prepared by using Haake internal mixer. The mixing time was 10 minutes at 150°C with rotor speed 50 rpm…
Thermal barrier coating has proven to be effective in improving the thermal efficiency and initiation of an effective cooling system of the engine. In the present work the engine piston crown was plasma coated with 150μm thicknss of catalytic ceramic material Alumina-Titanium oxide (Al2O3-TiO2) over a 60μm thickness o…
The corrosion behavior of anodized powder metallurgy Al/2wt%Mg composites reinforced with the short fibre alumina SaffilTM was studied using potentiodynamic polarization in 3.5% NaCl solutions. The materials under investigation were fabricated using powder metallurgy route. Anodising process has been done to the mater…
The oxidation of hot-dip aluminized AISI 1020 steel coated with NaCl in static air at 700°C for a duration of time 49 h was studied by employing thermogravimetry, Scanning Electron Microscopy (SEM), Electron Dispersive Spectroscopy (EDS) and X-ray Diffraction (XRD) analysis. It was found that NaCl deposits markedly ac…
Amaç: Proksimal humerus kırıklarının kilitli plak ile cerrahi tedavisinde görülen komplikasyonlar değerlendirildi.Çalışma planı: Eylül 2005 ve Nisan 2009 tarihleri arasında kliniğimizde proksimal humerus kırığı nedeniyle açık redüksiyon ve kilitli plakla tedavi edilen 103 hasta (70 kadın, 33 erkek; ort. yaş 62; dağılı…
Cadmium sulfide (CdS) nanostructures were prepared with different spin coating speed 1000 and 3000 rpm and molarities of Cd:S to be 1.2 to 0.01 mol/L using sol-gel spin coating technique. It is found that the average grain size of CdS nanostructures deposited on glass substrates at 1000 and 3000 rpm is 43 to 4 nm resp…
In this study, anodic aluminum oxide (AAO) fabricated from phosphoric acid electrolyte at ambient temperature was used as the porous template, while a sol gel procedure was used for the preparation of the TiO2 sol with the addition of 0.1, 0.3, and 0.5 g of polyethylene glycol (PEG). The addition of PEG to the TiO2 so…
Thorium has a possibility as alternative nuclear reactor fuel. Thorium has several good neutronic properties so that could provide higher capacity factor, more stable and insoluble, very resistant to weapon-material proliferation, and more cost effective. On the other hand, regarding the previous study [, neutronic pe…
Colloidal nanodiamonds (NDs) have emerged as highly versatile platforms for the controlled delivery of therapeutics, proteins, DNA, and other assorted biological agents. The most common mechanism of drug loading onto the ND surface depends mainly on electrostatic interactions. Although a few reports have been publishe…
Antibacterial materials based on calcium phosphates have wide range of biomedical applications in the prevention of microbial infections. The synthesis of inorganic mineral component of bone i.e. hydroxyapatite was done with the addition of silver (Ag) (5-15 wt %) as antibacterial agent. The wet precipitation synthesi…
Pyramidal surface is commonly used as an antireflection structure. The weighted reflectance averaged by the AM 1.5 G spectrum is about 14%. In the photovoltaic field, lowering the surface reflectivity is an important approach to improve the conversion efficiency. Black silicon surface with low reflectivity is benefit…
Bacterial cellulose-based carbon nanotube has been synthesized by catalytic graphitization method. Bacterial cellulose (BS) is a source of cellulose produced from fermentation of medium by Acetobacter xylinum. Since it contains unbranch polymer linked by β-1.4 glucopyronose with hydroxil groups, BS is able to use as p…
We studied the crystallographic of Barium Zirconium Titanate thin films with Aluminum doped (BZAT). These films were prepared by sol-gel process and followed by spin coating. The sintering temperature is taken at 800°C and 900°C. We found that the crystallographic system of BZAT thin films have tetragonal structure wi…
