Transition metal selenides are widely used in electrocatalysis on account of high electrical conductivity, good stability and low cost. In this study, using nickel-cobalt layered double hydroxide (NiCo-LDH) as precursor, a simple two-step method was to prepare three-dimensional (3D) Setaria viridis-like NiCoSe2 nanoneedles arrays nickel foam (NiCoSe2 NNA/NF). Benefiting from the abundant cataly...

milk-based espresso coffee is one of the most popular beverages. foam is an essential quality characteristic for this beverage. foam formation and stability is mainly related to the milk composition. in this study the influence of three different concentrations of xanthan gum (0.05, 0.1 and 0.2 g dm-3) and three different temperatures (50, 60 and 70 °c) on foam stability were examined and exper...

In this study, Nickel-Chrome-Molybdenum alloy is manufactured using investment casting method with centrifugal device from a polyurethane foam model in regular and open-pore form, as hard tissue implant. The samples produced have 10, 20, 30 (±3) pores per inch 0.0008, 0.0017, 0.0027 g/mm3 densities, respectively. Young’s modulus, hardness mechanical behaviors of the were investigated by SEM, ED...
