Innovative Research Publications IRP India

Local variety of lime (Lemun tsami) was subjected to quasi-static compressive loading using Instron Universal Testing Machine at three levels of time after harvest; freshly harvested, one and two weeks after harvest. Creep parameters were determined by fitting the experimental data to the Burger’s Model and the obtained model equation for freshly harvested was: 𝑱 𝒕 = 𝟏. πŸ–πŸ’πŸ‘ + 𝟐. πŸ“πŸ—[ 1 – Π΅ (-t/2.933) ]+ 𝒕 πŸπŸπŸ”πŸŽ.πŸŽπŸ—πŸ‘ , R 2 = 0.98. The instantaneous creep compliance (Jo) was; 1.843, 3.137 and 4.116 1/MPa for freshly harvested, one and two weeks after harvest respectively while the corresponding instantaneous elasticity …

One-pot polyol process was combined with metal organic decomposition (MOD) method to fabricate a room-temperature NO2 gas sensor based on tin dioxide and reduced graphene oxide (SO2/RGO) nanocomposite films. X-ray diffractometry (XRD) and scanning electron microscopy (SEM) were used to analyze the structure and morphology of the fabricated films. The electrical and NO2 gas-sensing properties of SnO2 to which various amounts of RGO were added were measured in detail as a function of concentration of NO2 gas at room temperature, to elucidate the contribution of RGO to the NO2 gas-sensing capacity. The sensor that was based on a nanocomposite film …
