Heavy metal metals are non-biodegradable, have a remarkable ability to transfer through food chains and are potentially toxic for organisms.They are introduced tomarine environment via different anthropogenic sources. In this study, the ability of titanium dioxide nano-particle in transfer of Cr, Cu, Pb and Se metal through an aquatic food chain involving Ceratium tripos as the phytoplankton Da...

Olive leaves were used as biotemplates to synthesize diverse TiO2-CuO solids. A successful replication of trichomes and internal channels was evidenced by SEM, whereas a good dispersion Cu Ti atoms observed EDX. The systems consisted in pure anatase titania, with monoclinic CuO detected XRD Raman for large copper contents (over 15 wt%). XPS the existence strong interaction. Incorporation result...

Silicic, mafic and alkali intra-seam tonsteins have been known from SW China for a number of years. This paper reports on the geochemical compositions of coals and tonsteins from three seam sections of the Songzao Coalfield, SW China, and evaluates the geological factors responsible for the chemical characteristics of the coal seams, with emphasis on the influence from different types of volcan...

A unique molecular junction design is described, consisting of a molecular mono- or multilayer oriented between a conducting carbon substrate and a metallic top contact. The sp2 hybridized graphitic carbon substrate (pyrolyzed photoresist film, PPF) is flat on the scale of the molecular dimensions, and the molecular layer is bonded to the substrate via diazonium ion reduction to yield a strong,...

The development of novel and active photocatalysts to industrialize photocatalysis technology is still a challenging task. In this work, method presented prepare TiO2/SiO2 NSs by covering SiO2 nanospheres (NSs) with titanate-nanodiscs (TNDs) followed calcination. regard, are first synthesized then TNDs deposited on the using layer-by-layer deposition technique. morphology prepared samples analy...

A simple, robust and versatile hydrothermal synthesis route to in situ functionalized TiO2 nanoparticles was developed using titanium(IV) isopropoxide as Ti-precursor and selected silane coupling agents (3-aminopropyltriethoxysilane (APTES), 3-(2-aminoethylamino)propyldimethoxymethylsilane (AEAPS), and n-decyltriethoxysilane (DTES)). Spherical nanoparticles (ca. 9 nm) with narrow size distribut...

TiO2 composites with zeolite templated carbon (TiO2-ZTC) and activated carbon (TiO2-AC) were prepared and used as the photocatalysts for comparative studies with pure TiO2. TiO2-ZTC exhibited the highest rate of methylene blue degradation with a rate approximately 4 and 400 times higher than those of TiO2-AC and pure TiO2, respectively. Moreover, the highest catalytic performance of TiO2-ZTC in...

Use of indigestible markers such as Cr2O3, Fe2O3, and TiO2 are commonly used in animal studies to evaluate digesta rate of passage and nutrient digestibility. Yet, the potential impact of indigestible markers on fecal microbial ecology and subsequent VFA generation is not known. Two experiments utilizing a total of 72 individually fed finishing pigs were conducted to describe the impact of diet...
