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. 𝟖𝟒𝟑 + 𝟐. 𝟓𝟗[ 1 – е (-t/2.933) ]+ 𝒕 𝟏𝟏𝟔𝟎.𝟎𝟗𝟑 , 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 …


Fabrication Of Sno2/Reduced Graphene Oxide Nanocomposite Films For Sensing No2 Gas At Room-Temperature, Innovative Research Publications Irp India, Pi-Guey Su, Ching-Hsuan Wei A, Wei-Luen Shiu Apr 2015

Fabrication Of Sno2/Reduced Graphene Oxide Nanocomposite Films For Sensing No2 Gas At Room-Temperature, Innovative Research Publications Irp India, Pi-Guey Su, Ching-Hsuan Wei A, Wei-Luen Shiu

Innovative Research Publications IRP India

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 …


Application Of Colloidal Gas Aphron Suspensions Produced From Sapindus Mukorossi For Arsenic Removal From Contaminated Soil, Soumyadeep Mukhopadhyay Dr, Sumona Mukherjee Ms, Mohd Ali Hashim Dr, Bhaskar Sen Gupta Dr Jan 2015

Application Of Colloidal Gas Aphron Suspensions Produced From Sapindus Mukorossi For Arsenic Removal From Contaminated Soil, Soumyadeep Mukhopadhyay Dr, Sumona Mukherjee Ms, Mohd Ali Hashim Dr, Bhaskar Sen Gupta Dr

Colloidal gas aphron dispersions (CGAs) can be described as a system of microbubbles suspended homogenously in a liquid matrix. This work examines the performance of CGAs in comparison to surfactant solutions for washing low levels of arsenic from an iron rich soil. Sodium Dodecyl Sulfate (SDS) and saponin, a biodegradable surfactant, obtained from Sapindus mukorossi or soapnut fruit were used for generating CGAs and solutions for soil washing. Column washing experiments were performed in down-flow and up flow modes at a soil pH of 5 and 6 using varying concentration of SDS and soapnut solutions as well as CGAs. Soapnut …
