Introduction Polythiophenes, a very versatile class of conjugated polymers, are still of growing interest due to their potential applications in the development of new materials such as in the field of microelectronic and photovoltaic devices, electrochromic devices and energy storage[1].
Electrochromic materials are being studied extensively due to their applications in smart windows and display.
Conducting polymers, being a family of important electrochromic materials, have gained popularity due to their unique advantages, such as good processibility, high optical contrast, flexibility for large-area application and the ability to modify their structure to create multicolor electrochrome[3].

In our daily life, we will set distribution centers for those materials that are large quantities of and long distance.
Basing on distribution centers, we can develop the contact between different areas, form transportation network, arrange materials’ transportation reasonably, optimize the transportation routes and reduce the logistics cost.
But in our daily life, we will set distribution centers for those materials that are large quantities of and long distance between the supply areas and the demand areas except the direct transportation.

It is useful for the survival of Nigerian economy, as sources of basic raw materials for most industrial processes.
Materials and methods Sample collection 20 litres plastic container was used to collect the palm oil mill effluent from Nigeria Institute of oil palm research (NIFOR) NIFOR - Benin, Nigeria.
The high BOD and COD is an indication of the presence of large amount of organic and inorganic materials in the untreated POME.

Experimental procedures Raw materials PC is 42.5R grade produced by Shenzhen Haixing cement plant.
With time increasing, the amount of cementicious materials gradually used up by reacting with water, so the increase of strength rate changed slowly.

Introduction Concrete is widely used as a primary structural material in construction due to numerous advantages, such as strength, durability, ease of fabrication, and non-combustibility properties, it possesses over other construction materials.
Fire resistance and thermal behavior after exposure to a fire in the concrete structure depends on thermal and mechanical properties of concrete materials.
Materials and Methods Steel Fiber.
This is due to the steel fiber resist in concrete and there is a good bonding between materials and reinforcement that lead the crush occurred slowly.
