Novel material reduces heat released into the atmosphere
West Virginia University scientists have created a material that has the ability to decrease the amount of heat that power plants emit into the atmosphere . An oxide ceramic material developed by a team guided by Xueyan Song , Professor , and George B . Berry Chair of Engineering at the Benjamin M . Statler College of Engineering and Mineral Resources , resolves a long-standing efficiency problem plaguing thermoelectric generators . These devices can produce electricity from heat , including heat emissions from power plants , contributing to global warming . The innovative oxide ceramic Song ’ s group developed “ achieved a record-high performance that had been deemed impossible .
It demonstrated the best thermoelectric oxide ceramics reported in the field worldwide over the past 20 years , and the results open up new
research directions that could further increase performance ” she said . Cesar Octavio Romo de la Cruz , Yun Chen , Liang Liang , and Sergio A . Paredes Navia all contributed to the study , which was funded by the National Science Foundation for USD 639,784 . The findings have been published in Renewable and Sustainable Energy Reviews . Oxide ceramics are related to materials such as porcelain , pottery , clay bricks , cement , and silicon , but they contain different metallic elements . These materials are tough , resistant to heat and corrosion , are ideal for high-temperature air applications , and can be used to make thermoelectric generator components .
Nikkiso announces expansion in South Africa
Nikkiso Clean Energy & Industrial Gases Group is expanding its sales , service , and engineering capabilities for the African market by constructing a new facility . From it , the company will be providing support for all of its product offerings . The group is part of Nikkiso Company , located in Japan , which operates under Cryogenic Industries , based in the United States . Located in Waterfall , KwaZulu- Natal , South Africa , the facility was at first constructed to expand the operating range of the business in the continent of Africa and support
South Africa ’ s engineering and economic hubs in the region . By recruiting local engineers and field service support from local markets , Nikkiso will bring specific knowledge
from the local and regional markets . This enables the fabrication of more customised solutions from the site . Aside from the aforementioned technical sales support for the
Group ’ s products , contained within is a specialised air separation unit commissioning team . This enhances customer support which can be offered to the air separation market segment . From this facility , additional engineering support is expected to generate process and design optimisation solutions for operators in the region . The facility will also create LNG equipment to be used in the large natural gas expansion off the coast of Mozambique , and in the possible formation of virtual pipelines for LNG fuel to deter current electric grid reliability concerns .
