A metal-free organic–inorganic aqueous flow battery
(Nature Publishing Group, 2014)
As the fraction of electricity generation from intermittent renewable sources—such as solar or wind—grows, the ability to store large amounts of electrical energy is of increasing importance. Solid-electrode batteries ...
The energy penalty of post-combustion CO2 capture & storage and its implications for retrofitting the U.S. installed base
(Royal Society of Chemistry (RSC), 2009)
A review of the literature has found a factor of 4 spread in the estimated values of the energy penalty for post-combustion capture and storage of CO2 from pulverized-coal (PC) fired power plants. We elucidate the cause ...
Kinetic Disordering of Intermetallic Compounds Through First- and Second-Order Transitions by Rapid Solidification
(Springer Netherlands, 1992)
During rapid solidification of intermetallic compounds, the atoms may not have time to find the lowest-energy sites in the crystal, resulting in the growth of a solid with partially or completely suppressed chemical order. ...
Point Defect Engineered Si Sub-Bandgap Light-Emitting Diode
(2007)
We extensively study the propagation features of higher-order modes in a photonic crystal fiber (PCF). Our analysis is based on a full-vector modal technique specially adapted to accurately describe light propagation in ...
Nonequilibrium Partitioning During Rapid Solidification of Si-As Alloys
(Elsevier, 1995)
The velocity dependence of the partition coefficient was measured for rapid solidification of polycrystalline Si-4.5 at% As and Si-9 at% As alloys induced by pulsed laser melting. The results constitute the first test of ...
Pressure-Enhanced Crystallization Kinetics of Amorphous Si and Ge: Implications for Point-Defect Mechanisms
(American Institute of Physics, 1991)
The effects of hydrostatic pressure on the solid phase epitaxial growth (SPEG) rate, v, of intrinsic Ge (100) and undoped and doped Si (100) into their respective
self-implanted amorphous phases are reported. Samples were ...
Measurements of To Temperatures of Supersaturated Si-As Alloys
(Materials Research Society, 2010-02-19)
Solute Trapping of Group III, IV, and V Elements in Silicon by an Aperiodic Stepwise Growth Mechanism
(American Institute of Physics, 1994)
With rapid solidification following pulsed laser melting, we have measured the dependence on
interface orientation of the amount of solute trapping of several group III, IV, and V elements (As,
Ga, Ge, In, Sb, Sn) in ...
Evolution of Nanoporosity in Dealloying
(Nature Publishing Group, 2001)
Dealloying is a common corrosion process during which an alloy is 'parted' by the selective dissolution of the most electrochemically active of its elements. This process results in the formation of a nanoporous sponge ...
The Activation Strain Tensor: Nonhydrostatic Stress Effects on Crystal-Growth Kinetics
(American Physical Society, 1991)
The solid-phase epitaxial-growth rate of crystalline Si from the amorphous Si on the tensile side is greater than on the compressive side of elastically bent wafers, in marked contrast to the behavior observed under ...
