It can be seen that only the characteristic broad peaks of the graphitic structure with 2θ being 26⁰ and 43⁰ were detected on the AC sample, and these diffraction peaks become weaker with the increase of the metal loadings.
The characteristic peaks of the typical graphitic structure diffraction peaks become weaker with increasing the metal loadings.
Additionally, some peaks ascribed to carbolite structure increased intensity at 60NiO/AC with 2θ being 26.7⁰ and 29.5⁰ were detected.

Although the metal catalysts have been widely employed in photocatalytic reaction,the ability of transition metal ions incorporated TiO₂ nanotubes (NTs) prepared by wet impregnation method for heavy metal removal at low concentration is less studied especially in nanotubes structure.
As is well known, the Fermi level of copper is 4.65 eV, which is between gold (5.10 eV) and silver (4.26 eV), making copper an appropriate and cheap candidate to replace noble metals in modulating the band structure of TiO₂ nanotubes [3].One of the emerging techniques in the field of heavy metal removal is using photocatalyst mechanism [4].
In addition to obtain defined anatase structure, anodized sample were annealed at 400°C for 4 hours in argon gas with heating rate of 5°C/min using Lenton Tube Furnace.

UHPFRC was created by the modification of a commonly used cement-based concrete thanks to the development of construction chemistry and also by a different composition.
The fibre segregation and its non-homogeneous distribution in a structure magnificently affect the final mechanical parameters of the construction or the construction part.
Conclusions UHPFRC is a relatively new cement-based composite material with a great potential for its using in structures.

The physical and mechanical properties of hydrogels were studied on the universal ZWICK/ ROELL Z005 testing machine by compressing samples until their structure destroying.
They, as well as polymers in general, have a wide range of properties – they can be stable or biodegradable, soft or hard, elastic or rigid depending on the structure of their structural units.

These are composed of organic modified laminar silicate structures which allow obtaining a hybrid organic–inorganic structure.
Due to nanoclay platelets like structure, high aspect ratio and propensity to accelerate polymer crystallization, nanocomposite shows enhanced mechanical properties, reduced gas permeability and high thermal stability [2].
Generally the loading level, the dispersion, the surface chemistry of fillers and the viscosity of composites have effected on the Xc [3].
