Economist Letter to NTIA on 700 MHz Spectrum Auction [PDF]
As the 700 MHz auction approaches, we are writing to clear up a common misconception about the nature of spectrum auctions and the impact of various rules on auction revenues.Auctions, spectrum auctions, market ...

Mass Bounds for Flavour Mixing Bileptons
, 1999 Mass bounds for doubly-charged bilepton gauge bosons are derived from constraints on fermion pair production at LEP and lepton-flavour violating charged lepton decays.

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions
Advanced Functional Materials, EarlyView.DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Advanced Functional Materials, EarlyView.This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...

The response of cobalt-free Udimet 700 type alloy to modified heat treatments [PDF]
A superalloy based on Udimet 700, in which all of the cobalt was replaced by nickel, was prepared from hot isostatically pressed prealloyed powders. This material was given various heat treatments consisting of partial solutioning and aging in a sequence

Atomic Size Misfit for Electrocatalytic Small Molecule Activation
Advanced Functional Materials, EarlyView.This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

Essential Entry: Revenues in the 700 MHz Spectrum Auction [PDF]
A common misconception is that an open access provision on a sliver of the 700 MHz spectrum would reduce auction revenues. In fact, the open access, wholesale, and bidding credit provisions put forth by Frontline Wireless, will motivate new entry ...
