In this work, a Homotopy Perturbation Solution of magnetohydrodynamic (MHD) model of boundary-layer equations for an electrically conducting Nanofluid flow bounded by an infinite parallel vertical permeable plates is to be introduced. This model is applied to study the mass and heat transfer of an unsteady nanofluid, incompressible flow with suction, internal heat generation, Hall Effect and Ch...

Titanium dioxide has been widely used for photo-catalytic and self-cleaning activities. In this study, TiO2 /SiO2 /Co nanocomposite was prepared by sol-gel method in the presence of Polyvinyl Pyrrolidone (PVP), and Hydroxyl Propyl Cellulose (HPC) as additives, and characterized by IR spectra, Scanning Electron Microscopy (SEM), Energy Dispersive Analytical X-Ray (EDAX), and X-Ray Diffraction (X...

Titanium dioxide (TiO2) is one of the most widely studied photocatalysts during the past decades due to its ability to photo-oxidize harmful chemicals in both air and water to CO2 in the presence of UV light. TiO2 also shows promise for energy applications such as water splitting [1], as well as in photochemical solar cells [2]. TiO2 use has also been extended to large scale commercial producti...

Aim of Study: Bio lm of Candida albicans signify as a complex cellular congregation with major implication in pathogenicity. This kind of lifestyle of fungus as a biofilm can inhibit immune system function and antifungal therapy, thus complicates the treatment of infectious diseases, particularly in field of chronic infections associated with medical devices. In this study effects of Titanium d...

Nanosized titanium dioxide (TiO2) in its anatase form is the most frequently studied and as well as used photocatalyst. There are several syntheses procedures which enable to achieve photocatalytic TiO2. The solgel method utilizing titanium alkoxides is used most often. Alternative precursors such as titanium tetrachloride and titanyl sulphate are also frequently employed. Nowadays the environm...

We evaluated recently published articles relevant to the biological effects of titanium dioxide (TiO2) particles on local endogenous cells required for normal bone homeostasis, repair, and implant osseointegration. Structural characteristics, size, stability, and agglomeration of TiO2 particles alter the viability and behavior of multiple bone-related cell types. Resulting shifts in bone homeos...

Nanocomposites have improved aspect ratio and better mechanical properties when compared to the composites which had structures less than 100nm They are 1000 times tougher compared to conventional composites. Besides mechanical properties, nanocomposites also have improved electrical conductivity, thermal stability, chemically resistant, flame retardant and low permeability. TiO2 finds its best...

A phase change memory (PCM) cell with atomic layer deposition titanium dioxide bottom heating layer is investigated. The crystalline titanium dioxide heating layer promotes the temperature rise in the AlSb3Te layer which causes the reduction in the reset voltage compared to a conventional phase change memory cell. The improvement in thermal efficiency of the PCM cell mainly originates from the ...

Layered double hydroxide (LDH) has attracted considerable attention as a drug carrier. However, because of its poor in vivo behavior, polyethylene glycolylated (PEGylated) phospholipid must be used as a coformer to produce self-assembled core-shell nanoparticles. In the present study, we prepared a PEGylated phospholipid-coated LDH (PLDH) (PEG-PLDH) delivery system. The PEG-PLDH nanoparticles h...

A hydrothermal method for the synthesis of reduced graphene oxide/titanium dioxide filter (RGO/TiO2) and reduced graphene oxide/zinc oxide filter (RGO/ZnO) by using polypropylene (PP) porous filter is reported. Field emission scanning electron microscopy illustrated that the nanoparticles were uniformly distributed on the reduced graphene oxide nanosheets. Flexural tests showed that the physica...
