In addition to having a higher biodegradability and lower toxicity, those bio ILs could be synthesized by using renewable materials [23].
These reactions are quenched at the end of process caused by the sudden decompression of treat materials.

Another 2% CaF2 was added in the raw materials in order to boost the separation of iron and slag.
According to the ratio calculated before, all the raw materials was mixed and dried.
Secondly 12~15% water or sodium silicate was added to wetting the raw materials.

The fundamental process behind dye-semiconductor devices is charge transfer through the interfacial contact of different materials.
Although electronic charges can move from a donor material to an acceptor material, the state of both materials needs to be in alignment [7].
The surface of the two materials strongly influences transition energy, driving force energy, strong coupling, and potential.
Firstly, we estimated the radii of N719, D149, and TiO2 by inserting the molecular weight M and the mass density ρ of the materials from Tables 1 and 2 in Equation 11 with Avogadro's constant of N=6.02 ×1023 Moleculemol.

In this context, architects are typically less concerned with questions of materials, details, structure and construction, or drawings at a scale of 1:20 or more detailed [6, p. 54].
Designing a bridge, for example, is understood by most structural engineers as carefully considering structural efficiency, material and cost implications of known structural assemblies in relation to the specified design task.
Engineering departments are addressing such criticism with increasingly popular initiatives such as CIDO [7] to get engineers to "Conceive - Design - Implement - Operate" by moving students away from the numerical, technical engineering science approach.
