A comprehensive review on electrospun nanohybrid membranes for wastewater treatment
Beilstein J. Nanotechnol. 2022, 13, 137–159, doi:10.3762/bjnano.13.10
- incorporated Ag NPs into the same composite of PVA, PAA, and carboxyl-functionalized GO. The resulting membrane showed a remarkable photocatalytic decomposition efficiency for MB even after eight catalytic cycles at room temperature [81]. A novel functionalized HNT-incorporated PVDF nanofiltration membrane has
- ), nanofiltration (NF), and reverse osmosis (RO), depending on the membrane pore sizes and the applied pressure. A low pressure is applied for the highly porous membranes with large pores and the applied pressure increases with the decrease of the pore size. MF membranes have pore diameters in the range of 0.1–5 μm
A review on slip boundary conditions at the nanoscale: recent development and applications
Beilstein J. Nanotechnol. 2021, 12, 1237–1251, doi:10.3762/bjnano.12.91
- superhydrophobic microstructures, and it is found to increase with the increase of the square root of the Reynolds number in the limit of high Re [121]. 3.2 Nanofiltration As shown in Figure 10, electro-osmosis can play an important role in the area of nanofiltration, where membrane fouling is the main drawback
- Beskok compared a slip-modified theoretical model with the molecular dynamics simulation results. They found that the slip enhancement in the electro-osmotic flow is independent of the channel height, which can provide a theoretical basis for membrane fabrication of electrically assisted nanofiltration
- value in many areas, including drag reduction, nanofiltration, and in the development of unconventional reservoirs. For future works, the mechanism of negative slip length variation should deserve more attention. In addition, more applications of nanofluidic systems with tunable slip length in areas
Ultrathin hydrophobic films based on the metal organic framework UiO-66-COOH(Zr)
Beilstein J. Nanotechnol. 2019, 10, 654–665, doi:10.3762/bjnano.10.65
- onto different kinds of substrates using the Langmuir–Blodgett (LB) or Langmuir–Schaefer (LS) deposition methods. Furthermore, the use of these films for CO2 sensing [21][26] or organic solvent nanofiltration [27] has been investigated. Additionally, we have also explored the fabrication of mixed LB
Nanomanipulation and environmental nanotechnology
Beilstein J. Nanotechnol. 2014, 5, 2079–2080, doi:10.3762/bjnano.5.216
- based on polyethylene oxide. The surface reactivity of minerals in contact with aqueous solutions can be investigated by laser confocal microscopy, as shown on the example of dissolution of the mineral biotite in solutions with acid and basic pH. Recent nanofiltration techniques are reviewed with
Applicability and costs of nanofiltration in combination with photocatalysis for the treatment of dye house effluents
Beilstein J. Nanotechnol. 2014, 5, 476–484, doi:10.3762/bjnano.5.55
- Nanofiltration (NF) is a capable method for the separation of dyes, which can support and even improve the applicability of photocatalysis in effluent-treatment processes. The membrane process usually will need a special pre-treatment to avoid precipitation and fouling on the membrane surface. Conceptually NF
- industry effluent; environmental; membrane; nanofiltration; photocatalysis; UV; Introduction Textile processing comprises different operations such as pre-treatment, dyeing, washing of garments, printing and finishing and produces a large amount of polluted effluent. For processing one ton of textile, 230
- combination with certain pre-treatment steps, are applied in some textile works, but those nanofiltration applications do not yet reflect the state of the art, and are not yet adopted as standard techniques in the dye industry [5]. However, the major drawback of applying membrane processes in wastewater
