1. Biogenic N-P-codoped TiO₂: Synthesis, characterization and photocatalytic properties

Author:
Han, Ting; Fan, Tongxiang; Chow, Suk-Kwun; Zhang, Di

Subject:
X-ray diffraction; X-ray photoelectron spectroscopy; absorption; anions; cations; crops; crystals; irradiation; lamps; metals; nitrogen; oxides; phosphorus; red light; seeds
Abstract:
... Four typical kinds of crop seeds are studied as non-metallic bio-precursors to synthesize biogenic N-P-codoped TiO₂ (BNP-TiO₂). The as-prepared BNP-TiO₂ samples are characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), nitrogen-adsorption measurement and UV-Vis spectroscopy. The results show that BNP-TiO₂ possesses single anatase phase with mesopore structures, and nitr ...

Subject:
absorption; acetates; anions; bromides; chlorides; colorimetry; fluorides; iodides; molecular weight; nuclear magnetic resonance spectroscopy; phosphates; polymerization; polymers; thiourea; titration
Abstract:
... A polymeric sensor (PTH) containing naphthalimide signal moiety and thiourea recognition moiety for the detection of anions was synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization, which can guarantee controllable molecular weight, narrow molecular weight distribution, and precise polymer structure. Both PTH and its corresponding monomer (TH) showed naked-eye reco ...

Subject:
absorption; anions; chemical structure; composite polymers; molecular weight; polymethylmethacrylate; polystyrenes; solvents
Abstract:
... Here we report syntheses, photophysical properties, and morphologies of a series of coil-rod-coil ABA triblock copolymers containing highly regioregular poly(3-hexylthiophene) (P3HT) as the central rod block. A new methodology, based on the coupling reaction between living polymeric anions [polystyrene, polyisoprene, and poly(methyl methacrylate)] and aldehyde terminated P3HT, was successfully dev ...

Subject:
absorption; adsorption; anions; aquatic weeds; chlorophyll; diquat; lakes; leaves; particle size; prediction; risk; surface water; total suspended solids; turbidity; water quality; weed control; New Zealand
Abstract:
... An experimentally derived prediction tool is under development which aims to assess potential deactivation of diquat caused by water and deposits on plant leaf surfaces in New Zealand water bodies, where aquatic weeds are targeted for diquat treatment. Optimising the use and success of diquat is important not only in managing public confidence in the use of aquatic herbicides, but also in minimisi ...

Subject:
Zea mays; absorption; anions; corn; pH; roots; seedlings; sodium fluoride; temperature
Abstract:
... In selenite solutions, H₂SeO₃, HSeO$ _3^- $, and SeO<$>_3^{2-}<$> are in equilibrium in proportions that vary with solution pH. The physiological characteristics of selenite uptake were studied with excised roots of maize (Zea mays L.) seedlings at pH 3.0, 5.0, and 8.0. The results showed that 0.10 mM 2,4-dinitrophenol (DNP), 1.0 mM sodium fluoride (NaF), and a temperature of 4°C inhibited selenit ...

Abstract:
... The use of a functionalized latex nanoparticle coating as a new sorbent phase for solid-phase microextraction (SPME) was examined. By means of electrostatic absorption onto ionized silanol groups, a fused-silica rod was coated with polymeric nanoparticles functionalized with quaternary ammonium groups. Optimum conditions for the preparation of the coated fibre are presented. The fibre was used for ...

Abstract:
... Secretion of saliva as well as absorptive and secretory processes across forestomach epithelia ensures an optimal environment for microbial digestion in the forestomachs. Daily salivary secretion of sodium (Na+) exceeds the amount found in plasma by a factor of 2 to 3, while the secretion of bicarbonate (HCO3−) is 6 to 8 times higher than the amount of HCO3− in the total extracellular space. This ...
