Coke corresponds to 2/3–3/4 of the reducing agents in BF, and by partial replacement coking coals with 5–10% bio-coal, fossil CO2 emissions from BF can be lowered ~4–8%. Coking coal blends 5% 10% additions bio-coals (pre-treated biomass) different origins pre-treatment degrees were carbonized at laboratory scale a bio-coal addition technical scale, aiming understand impact on properties (ash am...

Peptone and Malmgren modified terrestrial orchid (MMTO) has been used as a growth medium for tissue culture applications. This research study was conducted to explore the influence of Mr. Trivedi’s biofield energy treatment on physicochemical properties of peptone and MMTO. The study was performed in two groups i.e. control and treated. The control group was kept aside as untreated, and the tre...

In this study, in-situ bulk polymerization was investigated for obtaining flame retardant polystyrene (PS). The halogenated and phosphoric compounds were used as flame retardant additives and Perkadox 30 was used as a synergist. The flammability of the PS was evaluated by thermogravimetric analyzer (TGA), limiting oxygen index (LOI) and UL-94 tests. The results show that polymerization process ...

The thermal decomposition behavior of the Fe(II), Co(II), Ni(II) and Zn(II) complexes of polydithiooxamide has been investigated by thermogravimetric analysis (TGA) at a heating rate of 20°C min-1 under nitrogen. The Coats-Redfern integral method is used to evaluate the kinetic parameters for the successive steps in the decomposition sequence observed in the TGA curves. The processes of thermal...

In this study, the effects of chemical modifications of oil palm mesocarp fiber (OPMF) via bleaching, silane coupling agents, and combinations of the two on the composition and morphology of OPMF were investigated. The chemically modified OPMF was characterized by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). The FTIR s...

Article history: Received on: 29/05/2014 Revised on: 12/06/2014 Accepted on: 30/06/2014 Available online: 28/07/2014 In this study effect of gamma irradiation sterilization and storage conditions on thermal properties of phase sensitive granisetron in situ forming implant (ISFI) was investigated. ISFI was prepared by mixing Poly (DLlactide-co-glycolide) (PLGA) with dimethylsulfoxide (DMSO) : pr...

Waste-printed circuit boards (WPCBs) account for approximately 3–6 wt% of total electronic waste. Due to their content thermosetting materials and added brominated fire retardants, recycling disposal is difficult not eco-friendly. Pyrolysis as a thermal degradation process may assist in the solution this problem. In addition, using biomass an additive can upgrade bio-oil fix bromines char. stud...

Abstract The function of a membrane in the fuel cell is critical to its success. major component direct methanol (DMFC) proton exchange (PEM) which must have conductivity, thermal stability, mechanical qualities, and low permeability. In this study case, film-forming structural properties Polyvinyl chloride (PVC) impelled us employ them for developing polyelectrolyte membranes (PEMs). To functi...
