Experimental Procedure Ten specimens of each of Aluminum (Al), Brass (Cu) and Steel (St) were machined at the same conditions.
Typical measurement results for Al sample with different cutting speeds (a, b, c and d) 4.
Increasing the feed rate, particularly, when cutting Al or Cu (Fig.2c & 2d) causes greater errors.

The structure of a TiO2/CdTe was already considered by Minnaert et. al. [6].
We consider an ETA solar cell based on Cu2ZnSnS4 thin film structure and TiO2 n-type nanoparticles which were recently proposed by Kurokawa et. al. [12].
Nanu et al. reported efficiencies up to 4% for TiO2/CuInS2 solar cells, without buffer layer [16].
Comparing with Experimental Reports The TiO2/CZTS as dye structure was also considered experimentally by Wang et. al [21].
This article considers numerically the characteristics of such a device in SCAPS-1D device modelling.

A series of tests were carried out on the concrete in both fresh and hardened states to evaluate the variation in concrete performance due to the varying percentages of WSF added to the different concrete mixtures. 2.1 UHPC Constituents Properties 2.1.1 Cement: Ordinary Portland cement (OPC) CEM I 42.5 N which was manufactured by EL-Suez company for Cement in Egypt, was used to prepare all concrete mixtures in this research.

Lungenschmied et.al. [9] resulted power efficiency of 0.035%.
After drying the substrates in N2, a paste of PEDOT:PSS (Orgacon EL-P3145) was screen printed onto the freshly prepared substrates using a nylon screen.
Lungenschmied et.al. [9] reported that the polymer solar cells with MDMO-PPV/PCBM active layer resulting Voc of 1.1 Volt and FF of 0.26.
However, this value is quite similar to the result reported by Lungenschmied et.al. [9].
