Over the past few years, photogenic fabrication of metal oxide nanoparticles has attracted considerable attention, owing to simple, eco-friendly, and non-toxic procedure. Herein, we fabricated NiO altered their optical properties by doping with a rare earth element (lanthanum) using Sesbania grandiflora broth for antibacterial applications. The lanthanum was systematically studied. prepared nan...

Metallic-based nanomaterials have had their characteristics significantly enhanced by the incorporation of traces strontium nanoparticles (NPs) into matrix. These elements considerably improve mechanical and biological response properties, as well tenacity, durability, drug release. They are utilized in chemosensors, electronics, medication delivery, cancer treatment, bone engineering, environm...

Three-dimensional holograms were recorded in a cerium-doped, strontium barium niobate (SBN:75) photorefractive crystal. These holograms are shown to not degrade after more than one week of continuous readout and to reconstruct reproductions of the original object with an observable field of view of approximately 35 degrees.

We present a theoretical study of the defect properties of pure and anion deficient strontium chloride. We examine intrinsic defects obtaining an anion Frenkel enthalpy in good agreement with experimental values. We show that alkali cation interstitials are important at low temperatures in monovalent doped crystals.

We report the first instance of deposition of preferentially oriented, nanocrystalline, and nanocolumnar strontium-doped lead zirconate titanate (PSZT) ferroelectric thin films directly on thermal silicon dioxide. No intermediate seed or activation layers were used between PSZT and silicon dioxide. The deposited thin films have been characterised using a combination of diffraction and microscop...

The finite-size effect on the evolution of the Griffiths phase (GP) is studied using nanoparticles of half-doped manganite Pr0.5Sr0.5MnO3 with different average particle sizes but with similar structural parameters. All the samples exhibit pronounced GP behavior. With reducing the particle size, the Griffiths temperature remains almost unchanged but the characteristic critical temperature [Form...

The electron doped manganite system, Bi0.125Ca0.875MnO3, exhibits large bulk magnetization of unknown origin. To select amongst possible magnetic ordering models, we have conducted temperature and magnetic field dependent small-angle neutron scattering measurements. Non-trivial spin structure has been revealed. Ferromagnetic spin clusters form in the antiferromagnetic background when temperatur...

We employ time-resolved resonant x-ray diffraction to study the melting of charge order and the associated insulator-to-metal transition in the doped manganite Pr_{0.5}Ca_{0.5}MnO_{3} after resonant excitation of a high-frequency infrared-active lattice mode. We find that the charge order reduces promptly and highly nonlinearly as function of excitation fluence. Density-functional theory calcul...
