Agro-industrial wastes and their utilization using solid state fermentation: a review

Abstract: Agricultural residues are rich in bioactive compounds. These residues can be used as an alternate source for the production of different products like biogas, biofuel, mushroom, and tempeh as the raw material in various researches and industries. The use of agro-industrial wastes as raw materials can help to reduce the production cost and also reduce the pollution load from the environment. Agro-industrial wastes are used for manufacturing of biofuels, enzymes, vitamins, antioxidants, animal feed, antibiotics, and other chemicals through solid state fermentation (SSF). A variety of microorganisms are used for the production of these valuable products through SSF processes. Therefore, SSF and their effect on the formation of value-added products are reviewed and discussed.

Structural and thermal studies of silver nanoparticles and electrical transport study of their thin films

Abstract: This work reports the preparation and characterization of silver nanoparticles synthesized through wet chemical solution method and of silver films deposited by dip-coating method X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), field emission transmission electron microscopy (FETEM), high-resolution transmission electron microscopy (HRTEM), selected area electron diffraction (SAED), and energy dispersive spectroscopy (EDX) have been used to characterize the prepared silver nanoparticles and thin film The morphology and crystal structure of silver nanoparticles have been determined by FESEM, HRTEM, and FETEM The average grain size of silver nanoparticles is found to be 175 nm The peaks in XRD pattern are in good agreement with that of face-centered-cubic form of metallic silver TGA/DTA results confirmed the weight loss and the exothermic reaction due to desorption of chemisorbed water The temperature dependence of resistivity of silver thin film, determined in the temperature range of 100-300 K, exhibit semiconducting behavior of the sample The sample shows the activated variable range hopping in the localized states near the Fermi level

Structural and Optical Characterization of ZnO Nanoparticles Synthesized by Microemulsion Route

Abstract: ZnO nanoparticles were synthesized by microemulsion route in W/S ratio of 5 at room temperature X-ray diffraction (XRD) pattern reveals wurtzite structure of ZnO nanoparticles Rod shape of ZnO nanoparticles of average particle size 100 to 120 nm were observed by transmission electron microscopy FT-IR spectra confirmed the adsorption of surfactant molecules at the surface of ZnO nanoparticles and presence of Zn-O bonding Thermal studies were carried out by the differential scanning calorimeter (DSC) techniques In addition, UV-Visible spectra were employed to estimate the band gap energy of ZnO nanoparticles
