We have fabricated a vertical type organic field effect transistor (OFET) using indenofluorenedione derivatives (IF-dione-F) as an n-type organic active material and dimethyldicyanoquinonediimine (DMDCNQI) as an n-type buffer layer. The configuration of the vertical type OFET was ITO (drain)/ IF-dione-F/Metal (gate)/I…
This work deals with the synthesis and the determination of some surface properties of a new anionic surfactant belonging to sulfonamide derivatives. The interest in this new surfactant is that its behavior in aqueous solution is interesting both from a fundamental and a practice point of view. Indeed, it is well know…
The ventilation system plays an important role in preventing the release and dispersal of radioactive materials. There are a set of radiation monitoring instruments installed in vantage points in the laboratory to monitor whether ambient radiation level is within safe limits. Novel implementation of collecting ventila…
Microscope mode imaging for secondary ion mass spectrometry is a technique with the promise of simultaneous high spatial resolution and high speed imaging of biomolecules from complex surfaces. Technological developments such as new position-sensitive detectors, in combination with polyatomic primary ion sources, are…
Process of terpolymerization of basic unsaturated components of liquid products of pyrolysis of straight-run gasoline in toluene solution has been studied as model of oligomerization of C9 fraction under the action of catalytic system TiCl4Al (C2H5)2Cl. Relative reactivity of styrene, indene and dicyclopentadiene (80-…
We have investigated of composite (1-x)Ba0.5Sr0.5Fe11.7Mn0.15Ti0.15 / xLa0.7Ba0.3MnO3 by conventional ceramic method. The sturcture of composite and complex impedance are carried out by XRD, SEM and Impedance Spectroscopy. With changing the weight ratio from x=0; 0.3; 0.5 and x=1 the phase exhibit the composite behavi…
Microstructuresand electrochemical properties of La0.73Ce0.27Ni3.25+xMn0.35Al0.15Cu0.75Fe0.25 alloys are investigated. XRD results indicate that all alloys are identified with LaNi5 phase with CaCu5 type hexagonal structure, and lattice parameter a, c and cell volume V decrease with increasing x value. Maximum dischar…

The effects of dynamic vulcanization on the thermal properties and swelling behaviour of vPE/rPE/EPDM blends were studied. The discarded polyethylene used in the study was obtained from local wire insulation industry. The thermal properties and swelling behaviour of the blends were analyzed. Results show that increasi…
The titanium dioxide (TiO2) is a semiconductor oxide photocatalys, which is chemically and biologically inert but exhibits excellent photolytic activity in the ultraviolet (UV) region. Progress in photocatalytic water disinfection requires understanding both concepts of TiO2 semiconductor as well the biochemistry of m…
Entropy drives the phase behavior of colloids ranging from dense suspensions of hard spheres or rods to dilute suspensions of hard spheres and depletants. Entropic ordering of anisotropic shapes into complex crystals, liquid crystals, and even quasicrystals has been demonstrated recently in computer simulations and ex…
Barium hexaferrite and strontium titanate are respectively well established permanent magnet and piezoelectric materials which are technologically and scientifically attractive due to their potential for various applications in the field of magnetic electronics functional materials. However, the material properties fo…
Linear low-density polyethylene (LLDPE)/soya spent powder blends with different blends ratio were prepared by using internal mixer. Soya spent powder was varied from 5 to 40 wt. The thermal degradability was assessed by subjecting the dumbbell sample to oven aging. Thermal aging was carried out for 5 weeks. The degrad…
Polymer blends are potential candidates for solar-energy conversion, due to their flexibility, ease of processing, and low costs. We report herein 2.6 cm2 active area of flexible polymer solar cells based on blends of polymeric semiconductor [poly (2-methoxy-5-(3,7-dimethyloctyloxy)-(para-phenylene vinylene)] (MDMO-PP…
Polypropylene (PP) biocomposite containing 5, 10, 15, 20 and 25wt% of sodium hydroxide treated palm fruitlet fiber (TPFF) were prepared using Z-blade at 180°C at 50rpm. The composite was introduced with 3wt % of maleated anhydride grafted polypropylene (PP-g-MAH) as compatibilizer. The composites were characterized by…
The deformation after ballistic impact loading of silicon carbide reinforced aluminium alloy composite is investigated in this research. The composite consists of 10 % volume fraction of silicon carbide particulate in a matrix of Al-7Si-Mg-Zn alloy and were produced through the squeeze casting process with a pressure…
Photon Enhanced Thermionic Emission (PETE) is a novel concept in solar energy conversion, which can efficiently harvest solar energy at elevated temperatures. However, the temperature dependence of material parameters has not been clearly stated so far. In this study, a model for carrier transport is presented based o…
The effect of thermal treatment conditions namely water pick-up, temperature and time on the morphological structure, bursting strength and wearabilities of polyester (PET) hollow staple fiber were investigated. The results show that changes in water pick-up, temperature and time may lead to an obvious change in burst…
Response function is a fundamental parameter for all detectors in order to analyze the energy distribution of gamma ray which undergoes scattering interaction with the material. The response functions of a 3 in. x 3 in. NaI(Tl) collimated detector for non axis detector-source geometry has been calculated using a Monte…
