Transparent polycrystalline ZnGa 2 O 4 ceramics are synthesized, for the first time, by combining high-energy ball milling, solid-state reaction and spark plasma sintering. They appear transparent in both visible near infrared (up to 9 μm) ranges after a post-SPS annealing air converting raw semiconductor into an electrical insulator. The maximum of transmittance is reached region, at around 2....

The aim of this research is to investigate microphone array techniques based condition monitoring (CM). In this paper, a cost effective microphone array configured with 4-sensors and data acquisition systems is investigated theoretically and experimentally to evaluate its performance in characterising sound sources in different acoustic environments. Time delay estimation (TDE) is used as a bas...

Treated distillery effluent (TDE) generated through biomethanated distillery effluent was applied to arable land for augmenting agricultural production. The TDE contains considerable amount of organic matter and salt besides its high plant nutrients content. With this background, an attempt was made. Field experiments were conducted to study the long term effect of TDE and inorganic fertilizers...

In this paper, ZnO thin film is deposited on slide glass substrate using the sol-gel process. Presenting well-defined orientation of ZnO thin films Nanostructure were obtained by dip coating of zinc acetate dihydrate, monoethanolamine (MEA), de-ionized water and isopropanol alcohol. The annealed ZnO thin films were transparent ca 85-90% in visible range with an absorption edges at about 375 nm....
