Molecular dynamics analysis of lattice site dependent oxygen ion diffusion in YBa2Cu3O7-delta: Exposing the origin of anisotropic oxygen diffusivity

, 2013
The oxygen diffusion in YBa2Cu3O7−δ (YBCO) at different temperatures and oxygen contents is explored by molecular dynamics simulations. At low temperatures, the diffusivity of oxygen ions in YBCO is found to be strongly dependent on the ...

Monolithic Oxidation Enables Ultrathin Vertically Graded Tantalum Oxide for Low‐Voltage, Low‐Variability Memristive Switching

Advanced Functional Materials, EarlyView.
Monolithic UV‐ozone oxidation of Ta forms an ultrathin Ta2O5/TaOx bilayer enabling resistive switching with a vertical defect gradient. A stoichiometric surface layer over an oxygen‐deficient sublayer promotes localized filament nucleation near the top interface, enabling low‐voltage operation, and reduced cycle‐to‐cycle variability.

Current Indiana Oxygen Headquarters, Indianapolis

, 1990
As Indiana Oxygen grew, it began to open satellite branch stores, the first in Muncie in 1978. The increased demand for gas products required Indiana Oxygen to move again in 1991 to a new state-of-the-industry palletized cylinder fill plant on ...

The unique allosteric property of crocodilian haemoglobin elucidated by cryo-EM

Nature Communications
The principal effect controlling the oxygen affinity of vertebrate haemoglobins (Hbs) is the allosteric switch between R and T forms with relatively high and low oxygen affinity respectively. Uniquely among jawed vertebrates, crocodilians possess Hb that

Matrix effects in the neutralization of He ions at a metal surface containing oxygen

, 2013
Charge exchange between He ions and a Ni(111) surface containing oxygen was studied by Low-Energy Ion Scattering, using 1.25 key He+ as primary ions. The energy resolved yield of positive ions was detected after backscattering from Ni or O for different ...

Spatially Regulated Lithium Plating via Li2O‐Rich Interphase Enables Durable Fast‐Charging Hybrid Lithium Batteries

Advanced Functional Materials, EarlyView.
A Li2O‐rich solid electrolyte interphase (SEI) is engineered on graphite through a propylene carbonate‐based electrolyte to spatially regulate Li plating. The homogeneous interphase lowers Li nucleation barriers, promotes conformal Li deposition around graphite particles, and suppresses dendritic accumulation, enabling durable hybrid Li‐ion/Li‐metal ...

Disentangling Bulk and Surface Contributions to Charge and Discharge Fading in High‐Voltage LiCoO2

Advanced Functional Materials, EarlyView.
High‐voltage operation of LiCoO2 accelerates capacity fading through bulk and surface degradation. By introducing a LiTaO3 coating to selectively suppress surface degradation, bulk and surface contributions to charge and discharge fading are decoupled.
