20 Times More Hydrogen Produced With New Catalyst
December 18, 2019 | Leave a Comment
Eindhoven University of Technology (TU/e) researchers have now developed a pure platinum alternative with a 20x higher activity. It is a catalyst with hollow nanocages of an alloy of nickel and platinum. Working together with Chinese, Singaporean and Japanese researchers, TU/e researcher Emiel Hensen wants to use this new catalyst to develop a refrigerator-size electrolyzer […]

New World Record Set For Making Electricity From Heat
December 17, 2019 | 1 Comment
Vienna University of Technology (TU Wien,Vienna) scientists have now developed a completely new material with a ZT value of 5 to 6. It is so effective that it could be used to provide energy for sensors or even small computer processors. Thermoelectric materials convert heat into electrical energy. The amount of energy that can be […]

The Hunt For Perovskite Solar Cell Efficiency Gets Results
December 12, 2019 | 1 Comment
A Helmholtz-Zentrum Berlin (HBZ) für Materialien und Energie team has demonstrated that hybrid halide perovskites crystallize without an inversion center. Interactions between the organic molecules and adjacent iodine atoms can lead to the formation of ferroelectric domains, which, indirectly, can result in higher solar-cell efficiencies. The formation of these ferroelectric domains cannot occur in purely […]

New Method Makes Natural Gas From Sewage and Food Grease
December 11, 2019 | Leave a Comment
North Carolina State University researchers have developed what is, to date, the most efficient means of converting sewage sludge and restaurant grease into natural gas. The team’s research paper has been published in the journal Water Research. After treating sewage, wastewater treatment plants are left with solid sludge, called biosolids. For years, utilities have treated […]

A New Method To Find Geothermal Heat Sources
December 10, 2019 | Leave a Comment
A GFZ GeoForschungsZentrum Potsdam, Helmholtz Centre research team presented a new method for locating potential drilling sites that are covered by water. The new approach combines bathymetry measurements with geochemical profiles. The research offers in part an answer to: Where to drill? This is the basic question in the exploration of underground energy resources, such […]
