The POKAZATEL line list is currently the most complete theoretical of H2O monomer absorption lines. It contains lines up to dissociation energy ∼40 000 cm−1 (0.25 μm). atmospheric transmission ultraviolet (UV) radiation simulated with use from POKAZATEL. broadening parameters in UV region are determined more accurately different approximations. shown that contribution can attain 0.03 near 25 at...

The petroleum compounds were photocatalytically remediated from water using graphene (G)titanium oxide (TiO2) nanocomposite material in visible light radiation. The G-TiO2 nanocomposite was synthesized using sol-gel technique, and its structural & morphological properties were studied using scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), part...

In this study, free-standing expanded graphite chitosan (EG-chitosan) nanocomposite films have been prepared using a novel green and simple preparation method, starting from a commercial expandable graphite (GIC). The in situ exfoliation of GIC by a solvent-free sonication method was monitored as a function of the process parameters using X-ray diffraction (XRD), transmission electron microscop...

ZnFe2O4 nanocomposites have been prepared by a simple co‐precipitation method. The prepared samples were characterized by Scanning Electron Microscopy (SEM), Powder X‐ray Diffraction (XRD), Energy Disperse X‐ray Analysis (EDX), Transmission electron microscopy (TEM) and UV‐visible absorption spectral techniques. Conductivity measurements show a transition from ferrimagnetism to...

Samarium-doped ZnO hierarchical micro/nanospheres (Sm/ZnO) were synthesized via a facile and surfactant-free chemical solution route. The obtained products were characterized by field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX), UV–visible diffuse reflectance spectroscopy (UV-vis DRS) and photolumi...

Galctose oxidase nanoaggregates have been prepared by chemical desolvation method involving the crosslinkng agent glutaraldehyde. These enzyme nanoagregates have been characterized by transmission electron microscopy(TEM), UV visible spectroscopy, Fourier transform infrared spectroscopy (FTIR). TEM reveals the globular spherical nanostructured form upto the range of 20nm. UV visible spectroscop...

In this work, we report synthesis and characterization of Bi2O3 nanoparticles loaded on mesoporous MCM-41 nanoparticles by a simple solid-state dispersion (SSD) method. Monoclinic bismuth oxide nanoparticles were prepared by polyacrylamide gel method and used as loading materials on the prepared mesoporous MCM-41 as a supporting material. Fourier transform infrared spectroscopy (FT-IR), X-ray p...

My summer research has introduced me to the rewards and frustrations of working in a bioengineering lab. In Dr. Roeder’s lab, I studied the relationship between the physical and optical properties of a specific type of nanoparticles (NPs). Dr. Nallathamby taught me novel methods of synthesizing silica-gold core-shell NPs, and I gained experience in characterizing these nanoparticles. I learned ...
