Cathode materials should have a high specific capacity, a homogenous potential profile, and a stable phase.
Also, materials should have a high ionic and electronic conductivity, because they are related to the accepting and releasing of the electron in the electrochemical process.

Measuring the thermal conductivity of Sn-based alloys are vital since they are mainly used in soldering and temperature sensitive materials in sprinklers.
λ= Q4πd ∆Td ∆ln t (2.2) When measuring the thermal conductivity of the electrical conductivity materials such as metals and alloys, the electrical leakage from the hot wire to the sample has to be avoided.
To avoid starting convention in the oil bath, a cover made of the heat insulating material was put onto it in measurements.
In materials, both electron and lattice contribute to the thermal conduction properties.

The coal mining mode of paste-like fill shows the connotation and characteristics of green mining both in the filling materials and mining backfill technology.
Obviously, if cemented filling technology in mental mines is applied to mining in collieries, the inevitable result is that the sources of filling materials are inextricable and filling cost is too high.
Therefore, developing new cementitious materials, broadening the sources of filling materials and lowering the filling cost will be the keys.

The Ultrasonic Method is usable for metallic, non-metallic and composite materials.
The advantage: wave is propagated throught large layers in the materials, where the signals with lower frequencies are attenuated quickly.
The velocity of the wave propagation is different for various types of the materials.
