Earth Abundant Element Type I Clathrate Phases

Earth abundant element clathrate phases are of interest for a number of applications ranging from photovoltaics to thermoelectrics. Silicon-containing type I clathrate is a framework structure with the stoichiometry A8-xSi46 (A = guest atom such as alkali metal) that can be tuned by alloying and doping with other elements. The type I clathrate framework can be described as being composed of two...

High energy density rechargeable magnesium battery using earth-abundant and non-toxic elements

Rechargeable magnesium batteries are poised to be viable candidates for large-scale energy storage devices in smart grid communities and electric vehicles. However, the energy density of previously proposed rechargeable magnesium batteries is low, limited mainly by the cathode materials. Here, we present new design approaches for the cathode in order to realize a high-energy-density rechargeabl...

Photo-production of lactate from glyoxylate: how minerals can facilitate energy storage in a prebiotic world.

The reaction of glyoxylate with carbon dioxide to produce lactate is promoted when zinc sulfide is irradiated by ultraviolet light. These results, representing a model for the action of colloidal mineral semiconductors on early Earth, complete a consecutive series that culminates in entry-point molecules of the reductive tricarboxylic acid cycle.
