Metal doped TiO2 catalysts were synthesized by sol-gel method and their activities were determined for degradation of methyl orang as a pollutant. Nd-doped TiO2 showed the maximum activity comparing with others. Colloidal SiO2 was used as a support to increase the surface area and also the activity. Nano-TiO2/SiO2/Nd was synthesized by sol-gel method and it was characterized using XRD, XRF, SEM...

A novel binder system for cement-based composites depending upon the strength and durability characteristics is introduced in this study. The possibility of calcined red mud cement pastes with without colloidal nano-silica (CNS) over Ordinary Portland Cement paste (OPC) at three W/B ratios (0.3, 0.4, 0.5) evaluated. optimum percentage replacement by (15%) was selected from compressive values di...

Deposition of colloidal- and nano-scale particles on surfaces is critical to numerous natural and engineered environmental, health, and industrial applications ranging from drinking water treatment to semi-conductor manufacturing. Nano-scale surface roughness-induced hydrodynamic impacts on particle deposition were evaluated in the absence of an energy barrier to deposition in a parallel plate ...

Nanomaterials are known as chemically or biologically engineered materials having nanodimension of 1-100nm. These have been shown to exhibit various novel properties e.g. enhanced reactivity, greater sensing capability and improved mechanical strength. Various improved procedures are still under innovative considerations to enhance the potency, safety, and efficiency of chosen plasmid DNA vecto...

Development of delivery systems for new drug for its safe and effective delivery it into the body is an integral part of drug research program. This is particularly true due to increased incidence of adverse pharmacokinetic behavior of new drugs developed recently. Alternative delivery systems have been researched extensively not only to modulate their kinetic behavior in the body but also to a...

Passive method is a new procedure in stabilizing loose soils. This methodology is a type of interlocking soil particles structures. In order to optimum improve in this method, it is necessary to achieve proper penetration length and increase the shear strength of parameters. Researches have shown an increased resistance to liquefaction and decreased permeability due to colloidal Nano silica inj...

Transition metal dichalcogenides (TMDs) like molybdenum disulfide (MoS2) have unique optical properties such as strong luminescence and a tunable bandgap. However, the small interaction distance due to atomically thin nature of these materials is limitation for applications. In this study, significant enhancement A- B-exciton emission in MoS2 flakes through coupling with plasmonic Au nano-pyram...

The high infrared quantum yield, continuous absorption spectrum, and band edge tunability of colloidal quantum dots (QD) has opened up new opportunities to use luminescent down shifting for multispectral imaging in the infrared. We demonstrate a QD sensitized short wavelength infrared (SWIR) camera which is capable of UV-SWIR multispectral imaging. The application of multispectral cameras for U...
