“…Nanoparticles are said to be raw materials used in nanotechnology (1). These raw materials are found in different types, e.g., gold, copper, iron, nickel, and silver nanoparticles (2). Polysaccharide nano-silver (AgNPs) has attracted wide attention due to its high antibacterial, anti-inflammatory and anticancer activities, and is widely used in personal care products, textiles, food packaging, building materials and medical devices (3).…”

A novel polysaccharide (ZOP) was extracted from Zingiber officinale with ultrasonic assisted extraction method. ZOP monosaccharide composition and mole ratio is GlcA: GalA: Glc: Gal: Ara = 1.97:1.15:94.33:1.48:1.07. Then, the particle size of ZOP-NPs prepared by nano-precipitation method was 230.5 nm, and the polydispersity index (PDI) was 0.260. Using ZOP and ZOP-NPs as reductants and stabilizers, ZOP-AgNPs and ZOP-NPs-AgNPs were prepared. They were characterized by ultraviolet-visible spectrophotometer (UV-Vis), fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), transmission electron microscope (TEM), and X-ray diffraction (XRD). The silver chelation rate of polysaccharide silver nanoparticles (AgNPs) ranged from 68.70 to 82.12%. ZOP-AgNPs (0.5%, w/v; 1%, w/v) and ZOP-NPs-AgNPs (0.5%, w/v; 1%, w/v) exhibited a narrow particle size distribution of 31.1, 34.6, 25.1 and 27.6 nm, respectively. And the zeta potential values of them were−19.4,−21.6,−19.7,−23.8mV, respectively. The antioxidant and antibacterial activities of ZOP-NPs-AgNPs were superior to those of ZOP, ZOP-NPs and ZOP-AgNPs.

“…Since then research work in order to find out more about the properties has risen. The current stage of knowledge on the thermo-physical properties of nanofluids can be found in recent review papers [3,4,5,6,7,8,9,10,11,12,13]. Thermophysical properties and possible applications of nanofluids containing various types of carbon structures have been summarized in Refs.…”

The paper summarized results of experimental studies on thermophysical and electrical properties of ethylene glycol based nanofluids containing carbon black nanoparticles. Two types of nanoparticles differing in size and specific surface area were used to develop nanofluids. During examination the thermal conductivity, isobaric heat capacity, mass density, nanofluid-air surface tension, dynamic viscosity, refractive index and electrical conductivity were measured in strict controlled temperature 298.15 K. Obtained results indicate that the specific surface area have great influence on these fundamental properties of nanofluids developed with carbon nanoparticles.

“…In the results discussed above, the electroviscous effect observed in viscoelastic concentrated suspensions finds support in oscillatory rheology measurements (a subject for a forthcoming paper). This broadens the understanding of suspensions stability and rheology, with strong bearings in colloidal suspensions manipulation and consolidation methods, namely for nanofluids and nanoparticles electrical conductivity [31]. for the hard sphere model).…”
