PTFE‐Activated Graphene Overcomes Dispersion Challenges for Scalable Solvent‐Free Fabrication of Ultra‐Thick, High‐Performance Cathodes in Lithium Metal Batteries

open access: yesAdvanced Functional Materials, EarlyView.
PTFE nanoparticle–anchored rGO (rGO@PTFE) for scalable solvent‐free fabrication of ultra‐thick, high‐density cathodes, achieving high conductivity (9.55 S cm−1), lithium transference (0.73), and improved wettability, is developed. The resulting cathode delivers 15.2 mAh cm−2 areal and 563 mAh cm−3 volumetric capacities, with full cells exhibiting 637 ...

Global roles of currencies [PDF]

open access: yes
This paper presents a new concept – the global roles of currencies. The concept combines the domestic and international (cross-border) use of currencies and therefore captures the overall importance of different currencies in a globalised economy.

The relationship between entrepreneurship and economic development: is it U-shaped? [PDF]

open access: yes
Following a centuries-long decline in the rate of self-employment, a discontinuity in this downward trend is observed for many advanced economies starting in the 1970s and 1980s. In some countries the rate of self-employment appears to increase.

Dual‐Atom Dopants Activated Ruthenium Single‐Atom Alloy Boosting Hydrogen Evolution Electrocatalysis in Proton Exchange Membrane Water Electrolyzer

open access: yesAdvanced Functional Materials, EarlyView.
Ni1‐Bi1 dual‐atom dopants are achieved for activating Ru lattices without blocking noble atoms. This model exhibits an ultralow overpotential of 11.4 mV and superb stability at 10 mA cm−2 toward hydrogen evolution reaction, enabling a proton exchange membrane water electrolyzer that needs only 2.233 V to reach 3.0 A cm−2 and operates stably at 1.0 A cm−
