Effect of nano-TiO<sub>2</sub> on physical and rheological properties of asphalt cement
Abstract<p>In recent years, nano-modified asphalt has gained significant attraction from researchers in the design of asphalt pavement fields. The recently discovered Titanium dioxide nanoparticles (TiO<sub>2</sub>) are among the most exciting and promising nanomaterials. This study examines the effect of 1, 3, 5, and 7% of nano-TiO<sub>2</sub> by weight of asphalt on some of its rheological and hardened properties. The experimental study included physical and rheological properties. The asphalt penetration, softening point, ductility, and rotational viscometer tests indicate that 5% nano-TiO<sub>2</sub> is the ideal amount to be added to bitumen as a modifier. The </p>

A study of Some Electrical Properties of Te:S Thin Films Deposited at Angle Ó¨=70o
:Te S films
obliquely deposited films
In this research a study of some electrical properties Of (Te) thin films with(S) impurities of(1.2%) were deposited at( Ө=700)by thermal evaporation technique .The thicknesses of deposited films were (1050 , 1225 , 1400 , 1575 nm) on a glass substrates of different dimensions . From X-ray diffraction spectrum, the films are polycrystalline .A study of (I-V) characteristic for thin films, the measurements of electrical conductivity (σ)and electrical resistance(R )vs. temperature( T) are done. Further a measurement of thermoelectric power, see beck coefficient and activation energies ( Ea, Es) were computed

Assessment of some mechanical properties of PMMA/silica/zirconia nanocomposite as a denture base material
Abstract<p>In this research, nanocomposites of poly(methyl methacrylate) (PMMA) and a mixture of nano silica (SiO<sub>2</sub>) and nano zirconia (ZrO<sub>2</sub>) were prepared in different weight percentages of the nano fillers to improve some of the properties of PMMA resin to be used as a denture base material. The nano filles were surface modified with a coupling agent and added to the PMMA in different amounts. Impact strength, transverse strength, hardness and roughness were tested for both control and experimental groups. The results indicate that PMMA/silica/zirconia nanocomposites, prepared with 5% by weight of both types of fillers, had a slight increase in impact s</p>
