A smart cloud approach to asteroid deflection

, 2011
This paper presents a novel idea for the successful deflection of asteroids. Adapted initially from the kinematic impactor approach, this new concept – Smart Cloud – combines the relative benefits of the ion beam shepard in providing a large cloud of ...

Electrode and Microstructure Dependence of Oxygen Diffusion in Ferroelectric Hafnium Zirconium Oxide Thin Films

Advanced Functional Materials, EarlyView.
Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

Simulation of structural and electronic properties of amorphous tungsten oxycarbides

, 2012
Electron beam-induced deposition with tungsten hexacarbonyl W(CO)6 as precursors leads to granular deposits with varying compositions of tungsten, carbon and oxygen. Depending on the deposition conditions, the deposits are insulating or metallic.

Enhanced Photocatalytic Wastewater Purification and Bacterial Elimination via Copper Ion Irradiation‐Induced Modification of BiOCl

Advanced Science
The BiOCl photocatalyst possesses a relatively weak inherent intrinsic electric field property, which significantly hampers the separation efficiency of photogenerated carriers and, consequently, limits the full exploitation of its application potential.

Development and characterization of a dedicated dose monitor for ultrahigh-dose-rate scanned carbon-ion beams

Scientific Reports
The current monochromatic beam mode (i.e., uHDR irradiation mode) of the scanned carbon-ion beam lacks a dedicated dose monitor, making the beam control challenging.
