“…Constitutive model for densification and experimental results on cold sintering on Cu nanopowders were reported in in ref . One original approach to produce nanoparticles is by a non‐isothermal process of electrical wire explosion, where the formation of nanoparticles takes place by rapid vaporization followed by rapid condensation compared to the relatively slow evaporation–condensation process described in refs . In the electrical explosion method, very rapid heating is achieved by passing a current density of 10 6 –10 8 А сm −2 through the wire .…”

In the present paper, preparation of nanocomposite powders of mutually immiscible Fe and Cu metals with different Fe-to-Cu ratios by electric explosion of wires and their processing into bulk materials are reported. Near-fully dense nanocrystalline Fe-Cu specimens with high compressive and bending strengths are obtained by high pressure consolidation/cold sintering of the electrically exploded powders at 3 GPa. Reduction treatment in an H 2 -flow prior to consolidation results in an intimate contact between the oxide free powder surfaces and in an excellent inter-particle bonding integrity. The Cu-rich composition exhibits an attractive combination of high strength and relatively low electrical resistivity.

Abstract. In recent years, researches have paid much attention to the physical, chemical, biophysical and biochemical properties of a cell surface. It is known that most of the cells' surfaces are charged. This charge depends on the biochemical structure of the cell membranes. Therefore, measurement of a cell surface charge is a significant criterion that gives information about the cell surface. Evaluation of the cells zeta-potential is important to understand the interaction mechanisms of various drugs, antibiotics, as well as the interaction of nanoparticles with the cell surface. In this study, we use the dynamic light scattering method to detect the zeta-potential change of Neuro-2a tumor cells. It has been observed that zeta-potential shifted to negative values after exposure to metal oxide nanoparticles and inducing apoptosis.

“…Variations of the reaction conditions such as silver nitrate concentration, pH value of the mixture and the temperature of the liquid solution were known to influence the synthesis of nanoparticles [20] . Figure 5 revealed the effect of varying silver nitrate concentration on nanoparticles synthesis when the reaction was carried out at room temperature.…”

“…Silver plays an important role in drug delivery, wastewater treatment, agriculture, biosensor and textile industries [13][14][15] . The synthesis of nanoparticles by various physical and chemical methods, such as ultrasonic irradiation [16] , laser ablation [17] , evaporative cooling [18] , chemical vapor deposition [19] , explosion [20] , impregnation [21] , co-precipitation [22] , sol-gel [23] and deposition-precipitation [24] , has been reported extensively. However, there is still a need for a more economic, commercially and eco-friendly route to synthesize silver nanoparticles.…”

Abstract. In the present study, the silver nanoparticles (AgNPs) were biosynthesized using tea polyphenols in the silver nitrate solution. The tea polyphenols, which was extracted from the green tea leaves, acted as both reducing (from Ag + to Ag 0 ) and capping agent in the liquid phase. The synthesized AgNPs were characterized with UV-visible absorption spectrum, TEM, EDS spectrum and particles size distribution analysis. UV-visible absorption spectrum indicated a significant absorption peak at 425 nm related to the great synthesis of AgNPs in the aqueous solution. TEM images show the diameter of well dispersed AgNPs was around 28nm. The important parameters including pH value, silver nitrate concentration and temperature affected the synthetic reaction of AgNPs significantly. The AgNPs showed excellent catalytic activity in the degradation of Acid Violet 7 by NaBH 4 , and more than 97% Acid Violet 7 was degraded within 18 minutes.
