In this work, polytetrafluoroethylene (PTFE) conducting polymer bindered hematite nanostructure was prepared by using drop cast method. Ferric oxide (Fe2O3) powder mixed with PTFE was used in the initial solution. The gas sensing performance was studied towards NH3 gas for the prepared samples. Synthesized films were characterized using SEM, XRD, F...

Heterogeneous photocatalysis is an attractive alternative route to enhance the degradation of environmental pollutants. In this work, we have fabricated Fe2TiO5/TiO2 binary nanocomposites using natural ilmenite via bottom up approach. Synthesized nanocomposites were characterized by X-ray diffractometry, X-ray fluorescence, transmission electron mi...

In this paper, the feasibility of combining the optical mouse sensor and an encoder sensor for accurate odometry was presented. The system provides a good sensing capability rather than calculating distance using one kind of sensor. The weighted mean approach provided low uncertainty values as observed, +0.39 and -0.76 cm, respectively. The propose...

This proposal is about how to get filtered out ground water by using an economically beneficial filter system

Thin films of ferric oxide (Fe2O3) were synthesized by the doctor blade method starting from a solution of iron acetate and PEG binder. The samples were subsequently annealed at 500 0 C in air for one hour. The surface morphology of the samples was determined by SEM. The samples are consists of closely packed spherical particles in the size of a...

The present invention relates to a visible light sensitive p-n photodiode using earth abundant and non-toxic materials. The device consists of a Cu substrate as negative electrode and Cu2O n-type layer/CuI p-type layer to form p-n junction and a transparent conductive layer to collect electrons from active area of the photodiode. Hydrothermal and d...

Ferric oxide (α−Fe 2 O 3) thin films were fabricated on amorphous nonconductive and FTO conductive glass substrates starting from iron acetate nanoparticles by the doctor blade and the spin coating techniques. Thin films of α−Fe 2 O 3 with and without the PEG binder were investigated. Films were subsequently annealed at 500 0 C in air for 1 hour to...

Gesture Recognition is one of the most interesting topics in consumer electronics and wearable computing. It has been researched vastly due to its potential to produce enormous interaction capability to day-to-day life. Despite of the many different kind of gesture recognition techniques, still the field lacks a simple, efficient and real-time reco...
