Abstract Highly porous nanocomposite films were produced at room temperature from SiO 2 or TiO –SiO solutions synthesized by a sol–gel route in the presence of oxide nanoparticles. The photocatalytic behavior titania-based was controlled sol synthesis step, through three parameters: relative molar concentration between polymeric and condensed silica, reactivity hydrolysis active component. repo...

In this study, the oxidized cellulose nanofibrils from pineapple peel (PP-TOCNF) were prepared by TEMPO-mediated oxidation followed ball milling. The influence of degree on structure and properties PP-TOCNF investigated, including Fourier transform infrared spectroscopy , X-ray diffraction, atomic force microscope (AFM), photoelectron thermogravimetry, as well potential application in aerogels....

Washing processes cannot fully remove interfering species that remain on biosensing surfaces when a sample solution contains a high concentration of interfering species. This study reports an immunosensing scheme employing electroreduction-based electrochemical-chemical (EC) redox cycling that allows sensitive detection of vaccinia virus (VV) in a solution containing a high concentration of L-a...

Abstract: Hydroxyapatite, Ca10(PO4)6(OH)2, has been widely investigated for medical purposes because it is suitable for either direct clinical use as implants or tissue-engineering applications. In this work materials were successfully produced via hydrothermal transformation of aragonite, obtained from fresh cuttlefish bones, at 200°C and high pressures. Beyond low production cost, worldwide a...

An efficient plant regeneration system for Pinellia ternata (Thunb) Breit, an important wild Chinese herb, was established. The investigated factors influencing callus induction and plant regeneration included sterilizing agents, explant type, culture medium, and combinations of plant growth regulators in the medium. Ten min treatment of explants with 0.1% HgCl2 was more suitable for sterilizat...

Complexation of NpO(2)(+) with dipicolinic acid (DPA) has been investigated in 1 M NaClO(4) at 25 degrees C. Two complexes, NpO(2)(DPA)(-) and NpO(2)(DPA)(2)(3-), were identified, and the stability constants (log beta(1) and log beta(2)) were determined to be 8.68 and 12.31, respectively, by spectrophotometry. The enthalpies of the complexation (DeltaH(1) and DeltaH(2)) were measured to be -25....

OBJECTIVE In this study, a pilot-scale investigation was conducted to examine and compare the biotoxicity of the organic compounds in effluents from five treatment processes (P1-P5) where each process was combination of preoxidation (O3), coagulation, sedimentation, sand filtration, ozonation, granular activated carbon, biological activated carbon and chlorination (NaClO). METHODS Organic com...

Fusarium circinatum is one of the many threats to forests and Pinus nurseries all over world, being classified as a quarantine organism by several organizations governing bodies, such European Mediterranean Plant Protection Organization (EPPO) Union (EU), with associated phytosanitary measures in place prevent its spread through various means dispersal. One dispersal water used for irrigation n...
