Calcium carbonate (CaCO3) is widely used in pharmaceutical industries and as a supplement in probiotics. The present study was designed to evaluate the effect of biofield energy treatment on the physicochemical properties of the CaCO3. The CaCO3 powder was divided into two parts and referred as control and treated. The control part was remained untreated, whereas treated part was subjected to T...

The phenomenon of capillary condensation is studied through the weight change of condensed phase in an internally wetted porous pd catalyst pellet during the course of exothermic reacation of cyclohexane hydrogenation in a thermogravimetric analyzer (TGA). The direct measurement of condensed phase indicates that evaporation of condensed phase is confined to the macropores of catalyst pellet at ...

Agricultural residues have been traditionally used as energy resources for many years. In light of current environmental and fossil fuel supplies applications, agricultural are regarded sustainable production. However, the suitability to be renewable a co-fuel in coal combustion facilities has investigated. A thermal analysis was conducted investigate effect blending heating rate behavior Malay...

Plastic pyrolysis is widely studied and implemented at lab-scale but rarely modelled numerically. For the sake of designing efficient industrial reactors, modelling plastic process particle scale could be a prerequisite. Therefore, aim this work to model whole process, on scale, for polypropylene (PP) high density polyethylene (HDPE) inside thermogravimetric analyzer coupled with differential s...

The date palm is mainly cultivated for the production of sweet fruit. Date palm callus initiation medium (DPCIM) is used for plant tissue culture applications. The present work is intended to evaluate the impact of Mr. Trivedi’s biofield energy treatment on physical, thermal and spectral properties of the DPCIM. The control and treated DPCIM were evaluated by various analytical techniques such ...

Thermal stability studies on some metal soaps of Hura crepitans seed oil prepared by metathesis in aqueous alcohol solution were carried out. The kinetics of the decomposition was studied thermogravimetrically in the temperature range 160 – 200 C. The values of the rate constant are of the order 10min and temperature-dependent. The enthalpy of activation (∆H) of the initial stage of decompositi...

Abstract Carbon black was often used as a UV stabilizer, due to its ability absorb high-energy ultraviolet radiation. In this study, carbon added PVDF resin, and film with (PVDF/CB composite film) fabricated using precision co-extrusion casting mechanism. The properties of the films were characterized by differential scanning calorimetry (DSC), thermogravimetric analyzer (TGA), field emission e...

Poly(L-lactic acid)-co-bisphenol-A epoxy resin/vermiculite nanocomposites (PLLA–co-bis A ER/VMT) were prepared by in situ melt polycondensation of L-LA in the presence of amino-modified vermiculite. The fourier transform infrared (FTIR) spectra was used to investigate molecular interactions between the modified vermiculite and PLLA. Transmission electron microscopy (TEM) testing indicated that ...

In this study, the effect of drying temperature, from 50 °C to 90 °C, on the drying characteristics of powdered peanut shell was investigated, and an isothermal procedure was used to determine the moisture diffusivity and the activation energy. All the experiments were performed using a thermogravimetric analyzer (TGA) for rapidly achieving the isothermal condition and accurately recording the ...
