Alam et al deposited TiO2 thin films on silicon and glass substrates via the sol-gel process using titanium iso-propoxide [12], and reported that the cristallized TiO2 with an anatase structure is obtained after annealing at above 400°C.
The refractive index of TiO2 layers were measured with a DRE (EL X-02C) ellipsometer.
The refractive index of the prepared TiO2 thin films was measured with DRE (EL X-02C) ellipsometer.
R.Mechiakh et al [17] correlated this result to the densification of the film and pore destruction during different temperatures treatment.

Mounir and al [4] have studied the thermal characterization of the composite clay-cork for the different volume fraction of cork using the methods hot plate in the transient, and steady-state regime and Flash.
Mounir and al.[5] have studied the composite clay-wool which presents important characteristics in terms of thermal properties especially thermal conductivity which is 0.19 W.m-1.K-1 for the highest volume fraction of wool (y=0.124).
Afshin afshiari and al [7] revealed that a consensus was forming among experts to achieve emissions reductions at a lower cost by integrating the energy efficiency concepts.

In order to assess the effect of curing method on performance of AAS concrete, El-Hassan et al. [4] activated slag using grade N soldium silicate, also known as water glass (GW), combined with sodium hydroxide (NaOH) solution.
Shi et al. [6] investigated alkali-silica reaction (ASR) of AAS mortars activated used NaOH.
El-Hassan and Shehab [4] noted that intermitted curing of AAS concrete produced higher compressive strength after 28-days of curing compared to air curing and continuous curing under water.

Agostini et al. [2] proposed a solution of two-phase thermosyphon loop for the cooling of power-electronic semiconductor modules.
The heat transfer characteristics of two-phase flow inside minichannels were done using the latest correlations available in literature like for example: the El-Hajal et al. [15] correlation for void fraction, the Zhang-Webb [32] correlation for the friction pressure drop of two-phase flow in adiabatic regions, the Tran et al. [30] correlation for the friction pressure drop of two-phase flow in heated regions, the Cavallini et al. [12] correlation for the friction pressure drop of two-phase flow in cooled regions.
In addition, the following correlations were also used in calculations: the Mikielewicz et al. [23], Saitoh et al. [27] and Owhaib [26] correlations for the flow boiling heat transfer coefficient in minichannels and Mikielewicz et al. [23], the Shah [28] and the Tang et al. [29] correlation for the flow condensation heat transfer coefficient in minichannels.
The El-Hajal‘s [15] empirical correlation for the void fraction in two-phase separate flow model was applied in calculations.

The effect of a trace amount of Al on these
synthesis processes was examined.
The purity of the sintered Ti3SiC2 bulk was remarkably increased by addition of a small amount of Al.
Addition of 0.1mol Al remarkably decreased the strength of TiC peak.
However, further increasing Al to 0.3mol resulted in an increase in TiC content.
