Gecko‐Like Multi‐Directional High‐Power Magneto–Mechano–Electric Energy Harvesters for Self‐Powered, Hundred‐Meter‐Scale LoRa Communication

open access: yesAdvanced Science, EarlyView.
Gecko like multi directional high power magneto mechano electric energy harvester (MME EH) for self powered, hundred meter scale LoRa communication. Inspired by the symmetric and flexible limb motion of geckos, the biomimetic harvester enables coordinated bending twisting responses to weak, low frequency (50/60 Hz) stray magnetic fields from power ...

Experience in ensuring the strength of the supporting structures of locomotives and electric multiple units

open access: yesВестник Научно-исследовательского института железнодорожного транспорта, 2019
To ensure fatigue strength of metal structures in mechanical engineering, various approaches are practiced. One of them allows for the appearance of cyclic stresses in details with amplitudes exceeding the fatigue limit.

The Impact of the Euro on International Stability and Volatility [PDF]

open access: yes
We investigate the impact of EMU on macroeconomic volatility. The volatilities of inflation and nominal interest rates have declined, as has, more importantly, the volatility of real consumption growth.

Highly Robust Sn‐Based MAX Anodes Constructed via Ti6C Octahedral Outer Immobilization and A‐Layer Fe Inner Anchoring for Long‐Life Lithium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
How can Sn‐based anodes achieve high capacity and long‐life cycling? This work unlocks the potential anode structure by confining Sn in the A layer of MAX phase with Ti6C octahedra as outer immobilization and Fe as inner anchors. The introduction of Fe dramatically strengthens the Ti–Sn bond to enhance structural integrity, modulate interfacial ...

Euro area exports and imports: Do determinants of intra- and extra-EMU trade differ? [PDF]

open access: yes
The attempt is to explain EMU exports and imports, treating the euro area as one single economy. EMU trade is analysed separately for intra- and extra-EMU trade.

Nominal exchange rate regimes and relative price dispersion: on the importance of nominal exchange rate volatility for the width of the border [PDF]

open access: yes, 2003
Based on a broad set of regional aggregated and disaggregated consumer price index (CPI) data from major industrialized countries in Asia, North America and Europe we are examining the role that national borders play for goods market integration. In line

The Third‐Generation Magnetic Super‐Stable Mineralizer: Complete Removal and Separation of Multiple Heavy Metal Pollutants

open access: yesAdvanced Science, EarlyView.
The 3rd‐generation magnetic super‐stable mineralizer M‐MgAl‐700 features a core‐shell structure, strong superparamagnetism, large surface area, and abundant oxygen defects. It achieves exceptional Cd(II) and As(V) mineralization capacities, reducing both pollutants in co‐contaminated water and soil to meet national standards.

The Future of EMU: What Does the History of Monetary Unions Tell Us? [PDF]

open access: yes
The creation of EMU and the ECB has triggered a discussion of the future of EMU. Independent observers have pointed to a number of shortcomings or hazard areas' in the construction of EMU, such as the absence of a central lender of last resort function ...

Adhesion‐Driven Removal of Microplastics From Aquatic Systems by Using Microgel Glues

open access: yesAdvanced Science, EarlyView.
Soft polymeric microgels function as “glues” that aggregate diverse microplastics through multivalent adhesion, promoting their interfacial deposition and co‐precipitation for efficient removal from water. Remarkably, this approach remains effective even for nanoscale plastic particles as small as 50 nm.

Data-driven Prediction Method for High-speed Railway EMU Train Front and Rear Car Wheel Tread Defects

open access: yesChengshi guidao jiaotong yanjiu
Objective Tread defects are a primary manifestation of wheel failures in high-speed railway EMU (electrical multiple unites) trains, significantly impacting both EMU train operation safety and passenger ride comfort. Wheel tread defects are predominantly
