This paper aims to study effect of MQL using nano cutting oil on the hard milling process. The Box-Behnken experimental design was utilized to investigate the effects of input variables on the responses. The obtained results indicated that the concentration of nanoparticles, cutting speed and feed rate cause the strong influences on the surface roughness and cutting forces.

This paper presents a detailed experimental validation of an orthotropic laminate model to predict the vibroacoustic behavior of flat sandwich-composite plates with foam core. The accuracy of the model is investigated using a thin sandwich plate over a large frequency band. The sound transmission loss (STL) across several clamped sandwich-composite plates with polyurethane foam core is compared for different core density, different core thickness and different skin thickness.

This study presents thermodynamic approaches for selecting a hydrate former suitable for water treatment. Here, carbon dioxide (CO2) and 1,1,1,2-tetrafluoroethane (HFC-134a) were investigated as hydrate formers. Simulated studies of the hydrate formation by four formers were conducted at different NaCl concentrations (0.00, 1.75, and 3.50 wt%) to predict the phase-equilibrium conditions.
