“…The resonant frequency and tip radius were 60 kHz and 10 nm, respectively, and the AFM cantilever was made of silicon. For comparative analysis, the scan area was kept constant at 5 × 5 μm for all the samples because the roughness parameters depend on the scan size . Scanning probe image processing software (SPIP, version 6.7.2) was applied to analyze the AFM results and to determine the root mean square roughness (R rms ) of the membranes.…”

“…Despite the aforementioned significant properties of PPSU, there have been a few numbers of studies concerning the preparation and characterization of flat‐sheet PPSU membranes for liquid filtration. The publications on liquid filtration using this kind of membrane generally focused on pervaporation, nanofiltration of solvents, ultrafiltration (UF), and adsorption‐enhanced UF …”

In the present research, the low water flux of polyphenylsulfone membranes was addressed, and a novel improvement in their water permeation and fouling resistance was achieved using polyethylene glycol (PEG) as the hydrophilic additive. Scanning electron microscopy and field emission scanning electron microscopy, atomic force microscopy, attenuated total reflection Fourier‐transform infrared spectroscopy, thermogravimetric analysis, and tensile test were applied for the investigation of membrane morphology, surface topography, surface chemical structure, thermal stability, and mechanical properties, respectively. Moreover, the relative hydrophilicity/hydrophobicity of the membranes was assessed via determination of membrane water uptake capacity and water contact angle. The membrane performance was studied and compared by determination of pure water flux and filtration of canned beans production wastewater as well as bovine serum albumin solution. The filtration results indicated a remarkable pure water flux and 100% turbidity rejection provided by the polyphenylsulfone/PEG 20 000 membrane. In addition, it was confirmed that the amount of residual PEG within the membrane was increased with increasing PEG molecular weight and concentration.

“…Silicon nanoparticles are promising and have agricultural implications, and several new applications are being investigated for plants. In the agricultural sector, Si-NPs were observed to be applied as a weapon against heavy metal toxicity (Cui et al 2017 ), UVB stress (Tripathi et al 2017 ), salinity stress (Abdel-Haliem et al 2017 ), dehydration (Jullok et al 2016 ), etc. Moreover, additional novel applications of Si-NPs include their use as fertilizers, pesticides, and herbicides.…”

The beneficial effects of silicon and its role for plants are well established; however, the advantages of silicon nanoparticles over its bulk material are an area that is less explored. Silicon nanoparticles have distinctive physiological characteristics that allow them to enter plants and influence plant metabolic activities. The mesoporous nature of silicon nanoparticles also makes them good candidates as suitable nanocarriers for different molecules that may help in agriculture. Several studies have shown the importance of silicon nanoparticles in agriculture, but an overview of the related aspects was missing. Therefore, this review brings together the literature on silicon nanoparticles and discusses the impact of silicon nanoparticles on several aspects of agricultural sciences. The review also discusses the future application of silicon nanoparticles in plant growth, plant development, and improvement of plant productivity.

“…The global demand for acetic acid has been estimated at around 6.5 million metric tons per year, with approximately 1.5 Mt/year produced by recycling. Pervaporation can be an effective alternative to distillation in the recycling processes, helping obtain more concentrated acetic acid, and has been perceived as a clean process …”

The in situ generation of silver nanoparticles in a poly(vinyl alcohol)/poly(acrylic acid) (PVA/PAA) polymer matrix in the absence of any additional reducing agent is reported and tends to the membrane fabrication using solution‐casting. Its effect on the separation of a water/acetic acid mixture by pervaporation is described. The results of UV spectroscopy, scanning electron microscopy, and scanning electron microscopy/energy‐dispersive X‐ray spectroscopy analyses showed that the silver nanoparticles were successfully prepared and well dispersed in the polymer matrix. The increased hydrophilicity of the PVA/PAA membrane due to the presence of silver nanoparticles was confirmed by Fourier transform infrared spectroscopy, contact angle measurements, and membrane absorption studies. Pervaporation data for composite membranes showed a three‐fold increase in the flux value, while the initially decreased separation factor subsequently showed a constant value. Overall, the pervaporation data suggested that the presence of silver nanoparticles benefited the dehydration process.
