Ultrathin aluminum oxide layer boosts performance of garnet ceramic solid-state batteries

By April Gocha / January 17, 2017

Researchers at the University of Maryland have designed a way to insert an ultrathin layer of aluminum oxide in between a garnet ceramic electrolyte and electrodes of solid-state batteries, decreasing impedance by 300-fold and allowing the energy to flow.

MIT researchers improve efficiency of quantum-dot photovoltaic system by adding a forest of nanowires Photovoltaics based on tiny colloidal quantum dots have several potential advantages over other approaches to making solar cells. But there’s a tradeoff in designing such devices because of two contradictory needs for an effective PV: A solar cell’s absorbing layer needs…

Video: Wachsman on ‘Role of solid oxide fuel cells in a balanced energy strategy’

By / March 15, 2013

[flash http://ceramictechweekly.org/wp-content/video/wachsman_sofc_policy.flv mode=1 f={image=http://ceramictechweekly.org/wp-content/video/wachsman_sofc_policy.jpg}] Eric Wachsman been working with solid oxide fuel cells for nearly three decades and not just on the science and technology side. Wachsman also closely follows and writes on governmental policies insofar as these policies affect the development and deployment of SOFCs. In this video—an invited talk at the recent ICACC’13…

DOE supporting seven SOFC projects aimed at better coal conversion

By / September 4, 2012

Credit: NETL. I flinch when I hear the term “clean coal” because there is more than a little hyperbole imbedded in it. But, cleaner coal seems to me to be a more reasonable goal and I have heard a lot of reasonable presentations on how major strides in that direction could be made, especially ones based…
