Toughening β‐Ga2O3 via Mechanically Seeded Dislocations

open access: yesAdvanced Functional Materials, EarlyView.
β‐Ga2O3 is promising for next‐generation semiconductors but its brittleness limits flexible and high‐precision applications. Here, mechanically seeded dislocations introduced by surface deformation improved damage tolerance in (001) β‐Ga2O3. Nanoindentation and characterization show dislocations suppress cleavage cracks by enabling stable plastic ...

The Nonuniform Node Configuration of Wireless Sensor Networks for Long-Span Bridge Health Monitoring

open access: yesInternational Journal of Distributed Sensor Networks, 2013
This paper presents a nonuniform node configuration of wireless sensor networks (WSNs) for long-span bridge health monitoring. The methodology and strategy of two-phase node arrangement for nonuniform WSN configuration are firstly presented, and then ...

Multiple concentric annuli for characterizing spatially nonuniform backgrounds

open access: yes, 1998
A method is presented for estimating the background at a given location on a sky map by interpolating the estimated background from a set of concentric annuli which surround this location. If the background is nonuniform but smoothly varying, this method

SI‐bioATRP in Mesoporous Silica for Size‐Exclusion Driven Local Polymer Placement

open access: yesAdvanced Functional Materials, EarlyView.
An enzyme‐catalyzed surface‐initiated atom transfer radical polymerization (SI‐bioATRP) of an anionic monomer within mesoporous silica particles, using hemoglobin as a catalyst, allows for controlling the location of the formed polymer via size‐exclusion effects between the nanopores and the biomacromolecules, thereby opening routes to functional ...

New Family of Solvable 1D Heisenberg Models

open access: yes, 1994
Starting from a Calogero--Sutherland model with hyperbolic interaction confined by an external field with Morse potential we construct a Heisenberg spin chain with exchange interaction $\propto 1/\sinh^2 x$ on a lattice given in terms of the zeroes of ...

Toward Scalable Solutions for Silver‐Based Gas Diffusion Electrode Fabrication for the Electrochemical Conversion of CO2 – A Perspective

open access: yesAdvanced Functional Materials, EarlyView.
In this study, the preparation techniques for silver‐based gas diffusion electrodes used for the electrochemical reduction of carbon dioxide (eCO2R) are systematically reviewed and compared with respect to their scalability. In addition, physics‐based and data‐driven modeling approaches are discussed, and a perspective is given on how modeling can aid ...

Minimum emittance in storage rings with uniform or nonuniform dipoles

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2009
A simple treatment of minimum emittance theory in storage rings is presented, favoring vector and matrix forms for a more concise picture. Both conventional uniform dipoles and nonuniform dipoles with bending radius variation are treated. Simple formulas

Artificial Amorphous Interface Matters for Boosting High‐Voltage Stable LiCoO2 Cathode

open access: yesAdvanced Functional Materials, EarlyView.
The amorphization of phosphate‐based surface layer with favorable Li‐ion conducting kinetics is realized by precisely tailored atomic‐level fabrication. This amorphous coating enables the lithium cobalt oxide (LCO) cathode superior high‐voltage rate capability and cycling performance, owing to the fast interfacial ionic transport and maintained ...

Adaptive mesh based Haar wavelet approximation for a singularly perturbed integral boundary problem [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization
This research presents a nonuniform Haar wavelet approximation of a singularly perturbed convection-diffusion problem with an integral boundary. The problem is discretized by approximating the second derivative of the solution with the help of a ...
