“…Tying the fibrous particles of soap with each other will make the structure of the grease more concentrated [8]. Nanotechnology plays a prominent role in different applications [9][10][11][12][13][14][15]. Recently, the use of NPs, as additives for enhancing the lubrication and conduction of the base grease has attracted many attentions.…”

The aim of this research is to investigate the enhancement of lubricating and sealant properties, increase of the life time, and reduce of wear traces for lubricants and sealant greases. For this purpose, carbon dot (C-dot) nanoparticles (NPs) were synthesized successfully to add to the lithium based grease in 0.1, 0.2, 0.4, 0.6, 0.8 and 1 wt%. To better understand the effect of NPs on the properties of lithium based grease, carbon nanofiber (CNF) and Nano-Fullerene (C60) were also used in the mentioned weight percentages to add to the lithium based. NPs were well dispersed in the phase of base grease by the use of ultra-sonication. Variety of tests were done on the lithium base grease and all of the fabricated nanogreases and their results were then compared with each other. Using NPs did not remain any corrosive tracks for all of the nano-greases and caused the improvement in all their properties. Prepared nanogreases were also resistant to fuel, water, and aqueous alcohol in a specific period of time. CNFs with weight percentages in the range of 0.4-0.8 showed to be the optimum NPs content to be added to the lithium based grease in terms of improved properties.

In this research article, the PVDF (polyvinylidene fluoride)-PANI (polyaniline)-titanium nanotube (TNT) based nanocomposite membranes were synthesised through phase inversion method. The composition and structural properties of nanocomposite membranes were characterised by X-ray photoelectron spectroscopy (XPS), Fouriertransform infrared spectroscopy (FTIR), X-ray diffraction (XRD), atomic force microscopy (AFM) and scanning electron microscope (SEM). The significant properties of synthesised membranes such as distribution of pore size, thermal properties, mechanical properties, and photocatalytic behaviour of membranes were also studied. The hydrophilic properties of the composite membranes increased with filler content (PANI-TNT) and results in improved pure water flux (484.8 ± 2.9 L/m 2 h −1 ) compared to that (312.0 ± 1.91 L/m 2 h −1 ) of the pure PVDF membrane. The pure PVDF and nanocomposite membrane were further analysed in terms of their filtration properties such as adsorption of dyes (methyl orange, Allura red) and UV self-cleaning properties. The newly developed nanocomposite membranes showed excellent pollutant removal efficiency (~90%). The synthesised nanocomposite membranes also showed photocatalytic activities due to the presence of TNTs, and adsorption of methyl orange (MO) reduces significantly with the UV light irradiations. The UV self-cleaning property of the composite membrane was further confirmed due to their high flux recovery ratio of about 94%. The results show that embedded PANI-TNT within nanocomposite was photo-catalytically active and degrade the dye molecules from the surface of the nano composite membrane.
