In this study, apoptosis and related signaling induced by WC-Co nanoparticles were investigated in JB6 cells and rat lung macrophages. Electron spin resonance (ESR) and fluorescent staining indicated that both WC-Co nanoparticles and fine particles stimulated reactive oxygen species (ROS) generation. Catalase exhibited an inhibitory effect on WC-Co nanoparticle-induced ROS as well as mitochondr...

Three antimicrobial nanoparticle types (AMNP0, AMNP1, and AMNP2) produced using the TesimaTM thermal plasma technology were investigated and their compositions were determined using a combination of analytical methods. Scanning electron micrographs provided the morphology of these particles with observed sizes ranging from 10 to 50 nm, whilst FTIR spectra confirmed the absence of polar bonds an...

in this study, the elemental powders of aluminum and copper were initially subjected to mechanical alloying using an attrition ball mill under argon atmosphere to produce an al-4.5 wt% cu powder alloy. the wc nanoparticles were then added to the powder alloy and milled in a planetary ball mill to explore the role of the wc nanoparticles on the mechanical properties of the fabricated composite p...

BACKGROUND Tungsten carbide nanoparticles are being explored for their use in the manufacture of hard metals. To develop nanoparticles for broad applications, potential risks to human health and the environment should be evaluated and taken into consideration. OBJECTIVE We aimed to assess the toxicity of well-characterized tungsten carbide (WC) and cobalt-doped tungsten carbide (WC-Co) nanopa...

Exposure to hard metal tungsten carbide cobalt (WC-Co) "dusts" in enclosed industrial environments is known to contribute to the development of hard metal lung disease and an increased risk for lung cancer. Currently, the influence of local and systemic inflammation on disease progression following WC-Co exposure remains unclear. To better understand the relationship between WC-Co nanoparticle ...

Present research expresses an experimental investigation on nanoparticle use to enhance Solar still (SS) yield. Manganese Oxide (MNO2) is selected as a material and used in SS. The nanomaterial added with the black chrome paint of SS walls increase weight concentrations (WC) MNO2 have been from 20% 50 see its effect It has observed that heat transfer water temperature enhanced by paint. improve...

In this study, the synergistic effect of particle size dispersed phase and interface thermal resistance (R$_{int}$) between phases on phonon conductivity ($\kappa_{ph}$) (1-x)La$_{0.95}$Sr$_{0.05}$Co$_{0.95}$Mn$_{0.05}$O$_3$/(x)WC thermoelectric composite, is demonstrated. Further, correlation R$_{int}$ Kapitza radius discussed using Bruggeman's asymmetrical model. particular, polycrystalline L...
