By employing mixed inorganic precursors and finely tuning the ageing conditions, crack-free surfactant-templated mesoporous titania films of thickness up to 4 mm have been obtained efficiently. Low angle XRD and TEM show that the mesostructure of the multilayered films was maintained when calcined at the developed temperature of 350 uC, but those films developed crystallinity. A novel type of m...

We were successful in synthesizing periodic layered zinc acetate nanobelts through a hydrothermal solution process. One-dimensional structured ZnO nanoparticle aggregate was obtained by simple thermal annealing of the above-mentioned layered ZnO acetate nanobelts at 300 C. The morphology, microstructure, and composition of the synthesized ZnO and its precursors were characterized by transmissio...

Angle dispersive x-ray diffraction (ADXRD) is a basic non destructive tool for the determination of crystal structure. Energy tunability and high flux are added advantages in using synchrotron radiation (SR) source for ADXRD technique. We have installed an ADXRD beamline (BL-12) on Indus-2, the Indian synchrotron source. Indus-2 is a 2.5GeV, 300mA SR source. The beamline consists of a Si (311) ...

A combination of material science techniques is used to determine the influence of the growth parameters on structure and performance of photocathode materials. In-situ x-ray diffraction (XRD) and in-situ grazing incidence small angle x-ray scattering (GiSAXS), as well as after growth xray reflectivity (XRR) and θ/2θ XRD measurements were performed at synchrotron radiation sources. K3Sb is a pr...

Tanaka et al. (J. Am. Chem. Soc., 2017, 139, 1718) recently reported the three-dimensional (3D) structure of the oxygen evolving complex (OEC) of photosystem II (PSII) by X-ray diffraction (XRD) using extremely low X-ray doses of 0.03 and 0.12 MGy. They observed two different 3D structures of the CaMn4O5 cluster with different hydrogen-bonding interactions in the S1 state of OEC keeping the sur...

The sonochemical coprecipitation reaction with moderate ultrasound irradiation in a low vacuum environment was used to obtain aqueous colloidal suspensions of iron oxide nanoparticles (IONPs). synthesized magnetite were conjugated directly by folic acid using electrohydraulic discharges as processing technique before modification the surface nanoparticles. Electrohydraulic applied two operation...

Mn-doped nanocrystalline ZnO particles have been successfully synthesized at low temperature (80 ̊C) by the coprecipitation method using zinc sulfatehepta hydrate and NaOH. The structural and magnetic properties have been characterized using X-ray diffraction (XRD), Energy dispersive x-ray, vibrating sample magnetometer and electron spin resonance. XRD measurements revealed that the sample posse...

In the present work, Iranian natural zeolite particles (NZ) as an abundant and low-cost resource were modified by chemical covalent attachments of commercially available stearic acid (SA) with tunable hydrophobic/hydrophilic properties. The versatile, simple, and green technique of mechanogriding was performed for the hydrophobic derivatisation of NZ. The NZ and as-prepared modified particles w...
