AbstractThis paper summarizes the anti-corrosive and anti-erosive properties of water-ethylene glycol based commercial coolant dispersed with nanomaterials. Multiwalled carbon nanotubes (MWCNTs), silver nanoparticles (Ag) and nanosized alumina particles (Al2O3) are dispersed in 0.5% weight in automotive coolants and tested for anti-corrosive properties as per ASTM standards. Prior to dispersion, the nanomaterials are surface modified to get good stability in coolant solutions. The corrosion resistance is measured in terms of weight loss of materials that is commonly used in automotive systems. It is found that oxidized MWCNTs are suitable to automotive systems while silver and Al2O3 nanoparticles are found to be deleterious in nature.

There is a dearth of information regarding the safety of silver nanoparticles (Ag NPs) and multiwalled carbon nanotubes (MWCNTs) with respect to their impact on human/animal health and the environment. This study aimed to determine the half-maximum inhibitory concentration (IC50) of Ag NPs and MWCNTs by employing different doses and time interval combinations in buffalo bull spermatozoa. Semen samples containing 100 million spermatozoa each were incubated with 1, 10, 25, 50, 75 and 100 µg/mL of Ag NPs and MWCNTs at 37°C for 30, 60 and 120 min. Sperm viability was monitored by the MTT assay and eosin–nigrosin staining followed by estimation of IC50 values using correlation–regression analysis. Spermatozoa treated with IC50 doses of Ag NPs and MWCNTs were also assessed for different sperm functionality parameters including oxidative stress and membrane integrity. These parameters were observed to be significantly affected in treated spermatozoa compared with the controls. We concluded that both nanomaterials showed cytotoxicity, mediated principally via oxidative stress. This work has provided valuable toxicological information that will serve as a benchmark for future studies aimed at safe use of nanomaterials.
