Recent Drifts in pH-Sensitive Reverse Osmosis

Recent theoretical models to designate the membrane operations were mathematically itemized, after selective characterization of the PDROMs. The pH scale response of the membrane was confirmed using static adsorption and hydraulic pervasion result estimations. The flux across the PAm-ZTS membrane decreased with the lowering pH value, with drastic decreases between pH 4 and 7, and was both reversible and durable with pH shifts between~3 and~8. At lower pH 3, the individual pores were in a closed-state due to the prolonged structure of the amide chains on the porous surfaces. In contrast, at pH 8, the higher pH value, the membrane pores were in an open-state format, because of the collapsed structures of the amide chains. This grants a clear possible approach for manufacturing some pHresponsive composite membranes and inspires further design for their stimuli-responsive actions by incorporating molecularly designed macromolecules, synthesized by controlled polymerization.

Processing and physical properties of nanomaterials based Zn-Sn-O elements at various annealing temperatures

To obtain the optimal condition, ZTO nanoparticles were synthesized as a function of annealing temperature. The X-ray powder diffraction (XRD) shows the formation of single crystalline phase in the face-centred-cubic spinel structure. High resolution transmission electron microscopy (HRTEM) of annealed sample at 1100 °C shows agglomerated particles of ZTO. The optical characterization of the ZTO by UV–vis spectroscopy, photoluminescence (PL) and Raman spectroscopy confirmed the formation of pure phase related to ZTO. We note that the increase of annealing temperature from 700 °C to 950 °C demonstrates the appearance of ZTO, SnO2 and ZnO phases. Above 950 °C there is only formation of spinel structure of Zn2SnO4. This observation consistent with vibrational modes, provided by Raman spectroscopy. PL spectra exhibit large band in the visible range further UV-violet band. The later was assigned to the near band-edge emission. The white emission was attributed to oxygen vacancies, crystal defects and Zn or Sn interstitial in the ZTO host. Such emission shows the possible application of ZTO as white LED. However, the presence of various defects with visible emissions is a good motivation for application of ZTO as active electrode in dye sensitized solar cells application.

Photocatalytic Degradation of Methylene Blue and Antibacterial Activity of Mesoporous TiO2-SBA-15 Nanocomposite Based on Rice Husk

Adsorption Science & Technology

TiO2 photocatalyst is considered as an effective photocatalyst to remove the pollutants. Herein, the mesoporous TiO2-SBA-15 was prepared using the rice husk extract as the silica source. The fabricated nanocomposites were characterized using FTIR, small and wide angle XRD, Raman spectroscopy, UV-vis, BET surface area analysis, and HRTEM. The photocatalytic efficiency of the composites for the degradation of methylene blue (MB) has been evaluated under UV irradiation. Interestingly, due to the excellent dispersion of TiO2 on the wall of SBA-15 and good hydrophilicity, the nanocomposites displayed a good catalytic activity. The higher photodegradation performance was achieved by the composite containing 10 wt% TiO2 by which the MB was fully degraded within 15-20 min of irradiation. Besides, TiO2-SBA-15 could effectively inhibit the gro...

Recent theoretical models to designate the membrane operations were mathematically itemized, after selective characterization of the PDROMs. The pH scale response of the membrane was confirmed using static adsorption and hydraulic pervasion result estimations. The flux across the PAmZTS membrane decreased with the lowering pH value, with drastic decreases between pH 4 and 7, and was both reversible and durable with pH shifts between ~3 and ~8. At lower pH 3, the individual pores were in a closed-state due to the prolonged structure of the amide chains on the porous surfaces.
