Platform for assessing opto-electronic materials through spray deposition of composition gradients coupled with (semi-)automatized SEM/EDS, XRD, and FTS measurements.
Thin films of BixCo2-xMnO4 (x = 0, 0.1 and 0.3) were grown on quartz, LaAlO3 (LAO) and YBa2Cu3O7 (YBCO) buffer layer coated-LAO substrates by pulsed laser deposition (PLD). X-ray diffraction (XRD) and Raman scattering measurements showed that the thin films exhibit single phase polycrystalline cubic spinel structure on all the substrates. Near edge x-ray absorption fine structure (NEXAFS) studi...
This paper evaluates the suitability of X-ray diffraction (XRD) technique to characterize phase transformation during metal forming metastable austenitic steel AISI 304L. Due plastic deformation, from γ-austenite into α′-martensite occurs. The XRD peaks at specific 2θ angles give information about amount. Analyses results with different characterization techniques such as microscopic analysis, ...
The novel heterometallic aggregates [Ag(8)Cu(2)(C(2)C(6)H(4)X)(6)(PPh(2)C(6)H(4)PPh(2))(6)][PF(6)](4) (X = H, 1; OMe, 2; NMe(2), 3) were prepared by the self-assembly reactions starting from simple precursors. These compounds consist of the central [Ag(6)Cu(2)(C(2)C(6)H(4)X)(6)](2+) clusters capped by two tripodal fragments [Ag(diphosphine)(3)](+). The solid state structures of complexes 1 and ...
Bhasmas are potent Ayurvedic medicaments, biologically active and powerful healing preparations in all aspects. Properly prepared Bhasmas have not reported any serious untoward effects in clinical practice. Vanga Bhasma is an effective Ayurvedic medicine among various Bhasmas which are classically explained and advised specially in genitourinary disorders. XRD peaks of Vanga Bhasma are identifi...
In this research nanoparticles of Ni0.55Zn0.35Cu0.1Fe2O4 were synthesized by sol–gel auto-combustion method. Changes in phase constituents, microstructure and magnetic properties as a result of Zn and Cu additions were evaluated by X-ray diffraction (XRD), Field Emission Scanning Electron Microscope (FESEM), and Vibration Sample Magnetometer (VSM) techniques. XRD results show that the doped sam...
agal2o3 nanocomposite were synthesized by solution combustion technique using ammonium carbonate as a new fuel under simultaneous combustion of alumina and silver particles condition. samples prepared with different amount of silver, were characterized by xrd, bet, sem and optical absorption measurements. xrd analysis was used to determine the change in phase and size of the synthesized nanopar...
X-Ray diffraction measurements of lattice parameter were performed for (111) and (100) oriented 3C-SiC/Si epiwafers. Strain 3C-SiC epilayer Si substrate estimated the result was compared with routine wafer deformation measurements. An unexpected discrepancy observed between XRD curvature samples.
In this research zinc oxide (ZnO) nano-crystalline powders were prepared by sol-gel method using zinc acetate. The ZnO nanoparticles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet-visible (UV-Vis), Fourier transform infra-red (FT-IR) and energy dispersive X-ray (EDX) spectroscopy. The structure of nanoparticles was studied using XRD pattern. The c...
Luminescent solar concentrators (LSCs) generally consist of transparent polymer sheets doped with luminescent species. Incident sunlight is absorbed by the luminescent species and emitted with high quantum efficiency, such that emitted light is trapped in the sheet and travels to the edges where it can be collected by solar cells. LSCs offer potentially lower cost per Wp. This paper reviews res...
