“…Copper cobalt oxides are a family of metal oxides which have found important applications in electro-catalytic reactions and as thermoelectric material [1][2][3][4][5][6][7][8][9][10][11][12][13]. To enable improved designs for optimal performance in these applications, their physicochemical, electrochemical, magnetic, conductivity as well as thermal properties have been intensely studied, in conjunction with their structural characteristics [6,8,[13][14][15][16].…”

A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT2 Abstract Sol-gel dip-coated optical coatings, copper-cobalt oxides on aluminium substrates, were thermally treated at different annealing temperatures in the range 500 -650 °C. The resulting films were characterized using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), UV-Vis-NIR spectrophotometry and nanoindentation techniques. The crystallinity of CoCu 2 O 3 enhanced significantly, with increasing annealing temperature from 500 to 650 °C, while the electronic structure and bonding states of the copper-cobalt oxides matrix remained unchanged. UV-Vis-NIR analysis showed that the solar absorptance (α) of the coatings changed with increasing of annealing temperature and an optimum α (84.4%) was achieved at 550 °C, which also coincides to the maximum tensile residual stress of the coating.Nanoindentation tests exhibited an increasing trend in both the hardness (H) and elastic modulus (E) of the coatings with increase in annealing temperature, although a slight decrease in the H/E ratio was also observed. The experimental studies were complemented by Finite Element Modelling (FEM). The results showed that, under mechanical loading, the stress and plastic deformation were concentrated within the coating layers. As such, the likelihood of delamination of the coating layer upon unloading would be reduced.

“…The combinatorial approach differs from other systematic experimental methods [11][12][13][14][15] in one particularly important respect: combinatorial analysis relies on parallel or rapid serial testing of many catalyst samples, in such a way that the figure of merit (reaction rate, selectivity, stability, etc.) is determined without bias for all members of the library.…”

“…Additionally, an Al-containing phase of thehydrotalcite-type M 6 Al 2 (OH) 16 CO 3 was assigned by its characteristic reflections at 2theta = 11°(003), 24°(006) and 35°(009), [24,25]which became more prominent with increasing Cu/Co ratio. The X-ray amorphous character of the samples was retained even after calcination ( Fig.…”
