Metal Matrix composites (MMCs) are light weight, high-strength materials with potential application in areas such as automobile, aerospace, defence and other industries. MMCs are projected to significantly reduce the overall weight of the vehicle and aircraft while maintaining satisfactory structural strength. Micron and Nano-sized ceramic particle reinforced aluminum matrix composites fabricat...

Progress in the past year has occurred in the following areas: 1) understanding the role of pH and rheology on Al/water combustion, 2) encapsulation of nanoparticles in crystals for propellants, 3) disrupting ignition of aluminum with fluorocarbon inclusions, 4) the combustion of micron aluminum with hydrogen peroxide, and high speed PLIF applied to composite propellants, 5) the thermochemical ...

In this study, high energy conversion efficient dye-sensitized solar cells (DSSCs) were successfully fabricated by attaching a double anti-reflection (AR) layer, which is composed of a subwavelength moth-eye structured polymethyl methacrylate (PMMA) film and a polydimethylsiloxane (PDMS) film. An efficiency of up to 6.79% was achieved. The moth-eye structured PMMA film was fabricated by using a...

The nanoparticle technologies consisting of multiple layers of mixtures of activated carbon and ruthenium (IV) oxide for super capacitors are reported. The mono-particulate layer process described here is a modified Langmuir-Blodgett trough. We report the processes for a spray-coated zinc nanopowder electrode used as a counter-electrode forming a galvanic cell of extremely high charge storage c...

An experimental investigation of the combustion behavior of nano-aluminum (n-Al) and nano-aluminum oxide (n-Al2O3) particles stably suspended in biofuel (ethanol) as a secondary energy carrier was conducted. The heat of combustion (HoC) was studied using a modified static bomb calorimeter system. Combustion element composition and surface morphology were evaluated using a SEM/EDS system. N-Al a...

In this research, a practical study and appraisal of the thermal performance for solar collector with vacuum tube has conducted Two types nanomaterials (aluminum aluminum oxide) have added to distilled water nanoparticles diameters 30 nm 50 respectively. The were used in three several concentrations flow rates which as working fluid evacuated (ETSC) order increase efficiency beneficial gain. An...

nano-sized drugs have better distribution than their identical forms. magnesium is the cofactor of various enzymes in lipid and glucose metabolism. in this study the effect of nano-magnesium oxide (nano-mgo) on glucose concentration and lipid profile in diabetes induced mice was evaluated in 21 laboratory mice. mice were divided randomly into three equal groups (control, treatment and placebo)....
