Free rotation of nanoparticle in BEC We propose a new exiting possibility to observe free rotation of dopant particle in BEC to have a better understanding of superfluidity exhibited by BEC. We take the idea from the experiment of doped molecule in 4 He as it shows significance of superfluidity because of free rotation as …

Structural, morphological and optical properties of titanium dioxide nanomaterials prepared by sol gel technique Titanium dioxide (TiO 2 ) nanoparticles have been successfully prepared by sol-gel technique. Titanium tetrachloride and ethanol have been used as starting reagents where titanium tetrachloride dissolved in an ethanol as a precursor under acidic environment to study insight behaviour of …

Adsorption Properties of Graphene supported Gold: A DFT Study Graphene is a tri-coordinated two-dimensional (2D) honeycomb structured lattice of carbon atoms, first synthesized by Andre Geim and Konstantin Novoselov in the year 2004, for which they received the 2010 Nobel Prize in Physics. The bonding is very strong, hence it is highly stable and possesses …

Study of Structural, Electrical and Magnetic properties of Nd-Ti co-doped BiFeO_3 Nanoparticles Single-phase BFO nanoparticles with compositions Bi 0.9 Nd 0.1 FeO 3 and Bi 0.9 Nd 0.1 Fe 0.95 Ti 0.05 O 3 have been synthesized by low temperature citric acid assisted auto-combustion route. Thereafter, effect of the co-substitutions on structural, electrical and magnetic …

Fabrication and Characterization of Mach-Zehnder Interferometer on a single chip Mach-Zehnder and Michelson Interferometers are heart of many optical communication devices and components. These interferometers also find to be the key idea behind optical coherence tomography. On the other hand, miniaturization of these devices requires suitable waveguide design and integration of electro-optic or magneto-optic components …

Comparison of Protein interaction with different shaped PbS nanoparticlesand Corona formation Different shaped PbS nanoparticles are synthesized at room temperature by using reagents Lead Chloride, Sulfur powder, and Sodium borohydride in the Ethylene Diamine medium. Sodium borohydride is acted as a reducing agent, whereas Ethylene Diamine is used as a capping agent. The grown PbS …

Study of electronic and lattice dynamical properties of half-Heusler RuCrP alloy In the present study, we have explored the electronic and dynamical properties of half-Heusler compound RuCrP using density functional theory (DFT) implemented in Quantum ESPRESSO package based on the plane-wave basis and pseudopotential method. The exchange-correlation energy of the electrons was treated with the …

Growth, Structural, Optical, Thermal and Mechanical Studies of a Novel Nickel Sulphate Doped Sulphamic Acid Single Crystals for Optical Applications A novel good quality crystal of nickel sulphate doped sulphamic acid (NSSA) has been grown by slow evaporation solution growth technique at room temperature. The single crystal XRD confirm that the grown single crystal belongs …

Smartphone based colorimetric analyzer for detection of phosphate in water This paper reports a low-cost, compact, field-portable smartphone based colorimetric analyzer for detection of phosphate concentration in water medium. A 3D printed cradle housing all the optical components is integrated with the built-in camera of the smartphone using which photographs of the reagent treated test …

Review on Magnetism in nanomaterials and Superparamagnetism Nanotechnology play prominent role in the fabrication of novel materials by controlling the structure of matter at the nanodimensional scale. The particles at the nano scale change their material properties in a dramatic way showing unique properties. In many ferromagnetic materials when the size of the particle is …
