  • the influence of expanded graphite on thermal properties for paraffin high density polyethylene chlorinated paraffin Antimony Trioxide as a flame retardant phase change material
    Energy Conversion and Management, 2010
    Co-Authors: Ping Zhang, Lei Song, Hongdian Lu, Jian Wang, Yuan Hu
    Abstract:

    The influences of expanded graphite (EG) on the thermal properties of chlorinated paraffin (CP) and Antimony Trioxide (AT) on phase change material which bases on paraffin/high density polyethylene (HDPE) are studied. Differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), thermogravimetric analysis–Fourier transform infrared spectrometry (TGA–FTIR), microscale combustion calorimeter (MCC) and cone calorimeter (CONE) were used to evaluate the influence of EG on paraffin/HDPE/CP/AT system. The DSC results indicated that the latent heat value of PCM could be increased when the mass fraction of HDPE was decreased in the PCM, and EG could confine the molecular heat movement of paraffin. EG could improve the thermal stability and increase the char residue at high temperature for paraffin/HDPE/CP/AT hybrid. The volatilized products formed on thermal degradation of paraffin/HDPE/CP/AT with EG showed the release of CO2 gas was hastened and increased, and the amount of combustible gases were decreased by TGA–FTIR analysis. The MCC and CONE results presented that the flame retardant efficiency of CP/AT could be improved by adding EG in paraffin/HDPE/CP/AT system.

  • Antimony Trioxide induced apoptosis is dependent on sek1 jnk signaling
    Toxicology Letters, 2006
    Co-Authors: Koren K. Mann, Kelly Davison, Myrian Colombo, April L. Colosimo, Zuanel Diaz, Alessandra M.s. Padovani, Qi Guo, Wenli Gao, James P Scrivens, Sylvie Mader
    Abstract:

    Abstract Very little is known concerning the toxicity of Antimony, despite its commercial use as a flame retardant and medical use as a treatment for parasitic infections. Our previous studies show that Antimony Trioxide (Sb2O3) induces growth inhibition in patient-derived acute promyelocytic leukemia (APL) cell lines, a disease in which a related metal, arsenic Trioxide (As2O3), is used clinically. However, signaling pathways initiated by Sb2O3 treatment remain undefined. Here, we show that Sb2O3 treatment of APL cells is associated with increased apoptosis as well as differentiation markers. Sb2O3-induced reactive oxygen species (ROS) correlated with increased apoptosis. In addition, when we decreased the buffering capacity of the cell by depleting glutathione, ROS production and apoptosis was enhanced. Arsenic-resistant APL cells with increased glutathione levels exhibited increased cross-resistance to Sb2O3. Based on studies implicating c-jun kinase (JNK) in the mediation of the response to As2O3, we investigated the role for JNK in Sb2O3-induced apoptosis. Sb2O3 activates JNK and its downstream target, AP-1. In fibroblasts with a genetic deletion in SEK1, an upstream regulator of JNK, Sb2O3-induced growth inhibition as well as JNK activation was decreased. These data suggest roles for ROS and the SEK1/JNK pathway in the cytotoxicity associated with Sb2O3 exposure.

  • The effect of Antimony Trioxide on poly (vinyl alcohol)-lithium perchlorate based polymer electrolytes
    Ceramics International, 2013
    Co-Authors: Chin-shen Lim, S. Ramesh, Siti Rohana Majid
    Abstract:

    Abstract A new type of inorganic filler Antimony Trioxide (Sb 2 O 3 ) is used to prepare composite polymer electrolytes based on poly (vinyl alcohol) (PVA) and lithium perchlorate (LiClO 4 ) by solution casting technique. The incorporation of Sb 2 O 3 enhances the ionic conductivity at ambient temperature and exhibits the highest ionic conductivity value of 9.51×10 −5  S cm −1 upon the addition of 6 wt% Sb 2 O 3 . Thermogravimetric analyses (TGA) reveal that the second weight loss is reduced. This shows the improvement in thermal stability of electrolyte film upon addition of Sb 2 O 3 . Differential scanning calorimetry (DSC) analyses show that the glass transition temperature ( T g ) value decreases with incorporation of Sb 2 O 3 . X-ray diffraction (XRD) studies show that the addition of Sb 2 O 3 decreases the degree of crystallinity whereas scanning electron microscope (SEM) studies reveal the surface morphology of the prepared composite polymer electrolytes.

  • Thermogravimetry Studies Concerning the Synergism of Antimony Trioxide-Tin(II)Chloride Dihydrate on the Flame-Retardancy of a Cotton Fabric
    Polymer-Plastics Technology and Engineering, 2008
    Co-Authors: S. M. Mostashari, S. Baie
    Abstract:

    The synergistic effect between Antimony Trioxide and tin(II)chloride dihydrate on the flame-retardancy of a cotton fabric (woven construction massing 150 g/m2) was studied in this investigation. The laundered bone-dried massed specimens were impregnated with appropriate concentrations of individual aqueous Antimony Trioxide suspensions or tin(II)chloride dihydrate suspensions, and some bunches were impregnated with suitable admixed solutions of both chemicals. An acceptable synergistic effect was then experienced by using an admixed bath containing 0.06 formal Antimony Trioxide and 0.06 formal tin(II)chloride dihydrate suspensions for impartation of flame-retardancy to a cotton fabric. By using a vertical flame spread test the optimum mass of the mixture needed to impart flame-retardancy was obtained to be about 10.38 g anhydrous additives per 100 g fabric. Thermogravimetry (TG/DTG) outcomes of untreated and the supported cotton fabrics at the optimum addition were put in practice and their curves were co...

  • Thermogravimetry studies of cotton fabric’s flame-retardancy by means of synergism of lithium bromide and Antimony Trioxide
    Journal of Thermal Analysis and Calorimetry, 2008
    Co-Authors: S. M. Mostashari, S. Baie
    Abstract:

    The synergism of lithium bromide and Antimony Trioxide on the flame-retardancy of a cotton fabric (woven, plain 150 g m2) has been investigated in this study. The impregnations of cotton fabric with suitable individual additives and/or their appropriate admixed formulation were carried out. The flammability test has also been fulfilled using described procedure, in the earlier published articles. Their outcomes comply with thermogravimetry’s data. Moreover the latest mentioned outcomes support the catalytic effect of this synergism. Explanation of the data could be in favor of existing flame-retardation’s theories. Ultimately this synergism is in compliance with the green chemistry and economical viewpoints.
