Domain Wall Rebounds Driven by Competing Entropic and Spin‐Transfer Torques in Cylindrical Nanowires

open access: yesAdvanced Functional Materials, EarlyView.
Domain‐wall motion in cylindrical magnetic nanowires driven by nanosecond current pulses. Low current densities efficiently displace domain walls, whereas higher currents cause rebound at the wire ends. The effect results from the interplay between spin‐transfer torque and thermally induced processes, highlighting the role of thermal gradients in ...

Price stability, inflation convergence and diversity in EMU : does one size fit all? [PDF]

open access: yes, 2005
Using a unique data set of regional inflation rates we are examining the extent and dynamics of inflation dispersion in major EMU countries before and after the introduction of the euro.

Drug‐Free Thrombolysis Mediated by Physically Activated Micro/Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
Overview of particle‐mediated thrombolytic effects (thermal, mechanical, and chemical) and their activating physical stimuli (light, ultrasound, and magnetic field) in drug‐free thrombolysis. ABSTRACT Thrombus‐associated disorders rank among the world's leading causes of death, with ischemic heart disease and stroke as the main contributors.

Study on the technologies development trend of high speed EMUs

open access: yesHigh-speed Railway, 2023
High speed railway technologies are rapidly development in the world. The total distance of the high speed railway is more than 40,000 kilometers in China, and many types of high speed Electrical Multi-Units (EMUs) are operated. The top operation velocity of the train reaches 350 km/h. New science and technologies are developing rapidly. New generation

How wide are European borders? New evidence on the integration effects of monetary unions [PDF]

open access: yes, 2001
We use consumer price data for 81 European cities (in Germany, Austria, Switzerland, Italy, Spain and Portugal) to study deviations from the law-of-one-price before and during the European Economic and Monetary Union (EMU) by analysing both aggregate and

Nucleation‐Controlled Reconstruction of CuOx for Selective CO2 Electroreduction

open access: yesAdvanced Functional Materials, EarlyView.
The ratio of oxygen vacancies (Ov) and exposed Cu2O (111)/(200) of CuOx precatalyst is modulated by nucleation control of Cu(OH)2 precursor. Low Ov ratio and high ratio of Cu2O (111)/(200) in slow‐nucleated CuOx reconstructs to high‐coordinated oxide‐derived copper (OD‐Cu) during electrochemical CO2 reduction reaction (CO2RR) and exhibits enhanced ...
