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...

Nowadays, green chemistry and its advantages are generating interest of researchers toward ecofriendly biosynthesis of the metallic nanoparticles. In this research, a rapid, simple and green method was developed for the synthesis of silver nanoparticles using aqueous extract of Prangos ferulaceae leaves. The synthesized silver nanoparticles were characterized by UV-Vis spectroscopy, sc...

The present work deals with the synthesis and characterization of CdS nanoparticles with good thermal stability and optical properties by a novel and simple synthetic route. The nanoparticles were synthesized via chemical precipitation method in a single reaction vessel under ambient conditions. The prepared CdS nanoparticles were compared with the bulk CdS. The Optical properties were determin...

In this study, cellulose nanocrystals (CNC) was prepared and meso-tetrakis(4-nitrophenyl)porphyrin (TNPP) was immobilized on it. The product was identified by techniques of UV-Vis, fourier transform infrared (FT-IR), diffuse reflectance UV-Vis spectroscopy (DRS), energy-dispersive X-ray spectroscopy (EDX) and scanning electron microscopy (SEM). The effect of an amount of a loaded porphyrin comp...

The manuscript describes a method to obtain spectral aerosol optical thicknesses from measurements with a spectroradiometer in the UV-visible range. The direct solar light is inferred from the difference between total radiation and diffuse radiation. The latter is obtained by the use of a sun blocking disc. An error budget is presented. The results are validated against the measurements with a ...

Molecular sieves MCM-41 were synthesized from rice husk ash (RHA) as alternative sources of silica. The material was synthesized by a room temperature method from a gel with the molar composition SiO2: 1.6EA: 0.215HDTMABr: 325H2O with pH correction. The cetyltrimethylammonium bromide (CTMABr) was used as a structure template. Nanocomposite containing 5.0 and 10.0 wt.% of Cu was synthesized unde...

DNA sensing always has an open meadow of curiosity for biotechnologists and other researchers. Recently, in this field, we have introduced an emerging class of molecules containing azo and guanidine functionalities. In this study, we have synthesized three new compounds (UA1, UA6 and UA7) for potential application in DNA sensing in alcoholic medium. The synthesized materials were characterized ...

Novel mixed ligand complexes of Co(II), Cu(II) and Zn(II) of composistion [M(morphdtc)2(diamine)] were prepared where diamines en/dien/trien and morphdtc stands for morpholinedithiocarbamate. The complexes were characterised using IR, UV-Visible,Nuclear Magnetic Resonance, Electron spin resonance spectroscopic studies and Magnetic analysis using Vibrating sample magnetometer . The complexes wer...
