Oil shale is an important unconventional oil and gas resource, but it poorly utilized in the Dalianhe coal mining area, northeastern China. Systematic sampling test analysis were used to evaluate characteristics of quality. The research shows that between middle lower seams coal-bearing member a rich ore with high content, medium calorific value, ash volatile low moisture, ultralow sulfur conte...

Nanowires (NWs) are recently used in several sensor or actuator devices to improve their ordered characteristics. Silicon nanowire (Si NW) is one of the most attractive one-dimensional nanostructures semiconductors because of its unique electrical and optical properties. In this paper, silicon nanowire (Si NW), is synthesized and characterized for application in photovoltaic device. Si NWs are ...

with careful design, mixed microstructures consisting of fine plates of upper bainitic ferrite separated by thinfilms of stable retained austenite have exhibited impressive combinations of strength and toughness in highsiliconbainitic steels. the silicon suppresses the precipitation of brittle cementite leading to an improvement intoughness. the essential principles governing the optimisation o...

There are a many of needs for the development of SiC-based hydrogen sensor for harsh environment applications. We fabricated and investigated Pd/Ta2O5/SiC-based hydrogen sensors with MOS capacitor structure for high temperature process monitoring and leak detection applications in such automotive, chemical and petroleum industries as well as direct monitoring of combustion processes. In this wo...

The amount of used cooking oil waste is thrown into the sewer, which over time will compress sewer and can also pollute environment. Therefore, it would be good if this further processed bar soap that to wash clothes or other kitchenware. process making uses a cold process, does not use heating (stove). chemical NaOH. first stage purification crude oil. Purification done by soaking charcoal in ...
