Fig.1: (a) FESEM image of ZnO powder; (b-c) TEM images of of ZnO; (d) EDS spectrum of ZnO.
Fig. 1(a) shows the FESEM micrograph of a rubber-grade ZnO.
The particle sizes were verified from the TEM micrograph (Fig. 1(b-c)).
The EDS measurement reveals a high purity of ZnO with a higher atomic percentage of zinc (68.38%) compared to oxygen (31.62%) as illustrated in Fig. 1(d).

More than 600 DBPs have been reported [1].In order to overcome the limitations of traditional disinfection methods, research has focus on developing alternative disinfection methods.
Nanofluids are a class of fluids which consist of a base fluid with nanoparticles (1-100nm) suspended within them.
Figure 1 shows the total Coliforms number in the wastewater with the treatment of different concentrations of ZnO nanofluids.

Fig. 1 Caption of a typical figure.
In order to achieve the optimal results, a die was designed as shown in Fig. 1.
In addition, to ensure the billet heated directly in the die and to guarantee the smaller resistance of die than the billet, the geometry of the die shall be designed to follow the resistance formula, (1) Where R is the resistance of material, is the resistivity of material, l is the length of the material along the direction of current, and A is the cross sectional area normal to the current flow.

Characteristics bands of carbonate groups are shown on spectra of C-Si-HA samples: from B site (872 cm-1, 1409 cm-1, 1450 cm-1, 1466 cm-1), and A site (754 cm-1, 878 cm-1, 1545 cm-1).
More, spectra of C0.5-Si0.5-HA display the specific bands attributed to SiO4 substitution in hydroxyapatite structure: 503 cm-1 (ν2 : SiO4), 521 cm-1 (ν4 : SiO4), 750 cm-1 (ν1 : SiO4), 846 cm-1 (ν3 : SiO4), and 922 cm-1 (Si-OH) [8].
Likewise, the SiO2 specific bands (e.g. ~680 cm-1, ~792 cm-1 and ~870 cm-1 [8]) are not observed.

The spectrum of 90MoO3.10Nd2O3 glass is characterized by a strong band at 880 cm-1 and a not well resolved band near 720 cm-1.
The spectrum of 75MoO3.25Bi2O3 glass possesses a strong absorption band at 760 cm-1, shoulders at 920 cm-1 and 820 cm-1 and weak bands below 600 cm-1.
Fig. 1.
The main band at 760 cm-1 with the shoulders at 820 and 920 cm-1 are related to the vibration of distorted MoO4 units [3].
