Engineers Image Nanostructure Of A Solid Acid Catalyst And Boost Its Catalytic Activity (redOrbit)
A new view of an old problemThe Lehigh-Rice team attributes much of its success to the use, for the first time on tungstated zirconia catalysts, of aberration-corrected scanning transmission electron microscopy (STEM) and its integration with three optical spectroscopic techniques—Raman, infrared and ultraviolet-visible. Only by combining the microscopy and spectroscopy studies, says Wachs, was... »
Fuel Cells Get A Boost (redOrbit)
Image Caption: At left, a high-resolution Transmission Electron Microscopy image of platinum nanoparticles on a fuel cell’s electrode reveals surface steps that researchers say are responsible for dramatically improving efficiency. These steps are shown in greater detail in the diagram at the right. Image: Journal of American Chemical Society (get the story…) Related items Technology Could Speed... »
