Abstract:

Molybdenum dioxide (MoO2) is known for its catalytic activity toward reforming hydrocarbons. The objective of this study was to evaluate the effect of biofield energy treatment on physical, thermal, and structural properties in MoO2. The MoO2 powder sample was divided into two parts, one part was remained as untreated, called as control, while the other part was subjected to Mr. Trivedi’s biofield energy treatment and called as treated. Both control and treated samples were investigated using X-ray diffraction (XRD), thermogravimetric analysis (TGA), and Fourier transform infrared (FT-IR

Abstract:

In this work, calcium carbonate nanoparticles-polyethylene oxide nanofibers as organic–inorganic hybrid were prepared via in-situ electrospinning. Thus, electrospinning of polyethylene oxide solution saturated with calcium hydroxide was carried out in gaseous carbon dioxide atmosphere. Transmission electron microscopy (TEM) showed that calcium carbonate (CaCO3) nanoparticles were formed on the produced nanofibers of 200–300 nm in diameter. The existence of the formed CaCO3 was also proved by thermogravimetric analysis (TGA) via loss of gaseous CO2 related to the decomposition of CaCO3 at about

Abstract The 99Mo/99mTc generator is a chromatography column system that can be eluted to obtain technetium-99m (99mTc) for nuclear medicine applications in the hospital. Mesoporous titania is developed for the Mo adsorbent of a 99Mo/99mTc generator column employing low specific activity 99Mo produced by nuclear reactor irradiation of natural molybdenum. A symmetric triblock copolymer of P123 was used as a template to create mesoporous titania using the sol-gel process..

However, there is little research on their combined use in cement. The impact of SBA and limestone on the hardening and hydration property in blended cements were examined by testing properties of fresh and hardened mortars supplemented with TGA and XRD analysis.
