The covalent incorporation of inorganic building blocks into a polymer matrix to obtain stable and robust materials is a widely used concept in the field of organic-inorganic hybrid materials, and encompasses the use of different inorganic systems including (but not limited to) nanoparticles, mono- and polynuclear metal complexes and clusters, polyhedral oligomeric silsesquioxanes (POSS), polyo...

raphanus sativus l. (radish) plants were grown in waste water irrigated area of dinapur, a suburban area in the north east of varanasi, india. soil and plant characteristics were compared between fertilized (farmyard manure (fym), npk, and fym+n) and non-amended control treatments. compared to the control, plants grown in fym and fym+n amended soil showed a decrease in concentrations of heavy m...

in this article, hybrid organic-inorganic materials were prepared by free radical copolymerization of 2-hydroxyethyl methacrylate (hema) and 3-methacryloxy-propyltrimethoxysilane (mptms) via sol-gel process. the methoxysilane-containing copolymer precursors were synthesized at different compositions. these copolymer precursors were then hydrolyzed and condensed to produce phema-sio2 nanocomposi...

The properties of mineralogical and covalent inorganic polymers are brieffy described in the introductory part. Glass is an important polymer made up of rings and chains of silicate units which contain negatively charged oxygen atoms neutralized by positive metal ions. Glass and few other mineralogical types of inorganic polymers, like aluminum oxyde, could be fabricated into fibers and used as...

Combining multiple inorganic components is an effective approach to improve the mechanical properties of inorganic–organic hybrid materials. The can form interactions with organic polymer matrix, and there thus a need understand reinforcement mechanism under optimal combination particles. In this work, we prepared series dual particle–based titania/silica–poly(tetrahydrofuran)–poly( ? -caprolac...

a simple method has been employed to synthesize copper and copper oxide nanoparticles from copper (ii) succinate precursor by thermal decomposition method using oleylamine as a capping agent. the particles synthesized with oleylamine and triphenylphosphine were well dispersed nanoparticles obtained from x-ray diffraction (xrd). the synthesized copper nanoparticles were characterized by uv-visib...

The state of the art of modeling fluid flow in shale reservoirs is dominated by dual porosity models which divide the reservoirs into matrix blocks that significantly contribute to fluid storage and fracture networks which principally control flow capacity. However, recent extensive microscopic studies reveal that there exist massive microand nanopore systems in shale matrices. Because of this,...

Inorganic arsenic is a chronic exposure carcinogen. Analysis of UK baby rice revealed a median inorganic arsenic content (n=17) of 0.11 mg/kg. By plotting inorganic arsenic against total arsenic, it was found that inorganic concentrations increased linearly up to 0.25 mg/kg total arsenic, then plateaued at 0.16 mg/kg at higher total arsenic concentrations. Inorganic arsenic intake by babies (4-...
