Flexible Leaf‐Like Fuel Cell From Plasmonic Janus Nanosheet

open access: yesAdvanced Functional Materials, EarlyView.
A flexible leaf‐like fuel cell is fabricated by conductive gold nanowire sponge‐supported plasmonic Janus nanosheet, which can generate a power of 8.93 mW cm⁻2 with less than 10% performance deterioration even being bent or twisted. Further assembly in a tree‐like layout demonstrates omnidirectional light harvesting capability and wind resistance ...

Discovery of an Intrinsic Antiferromagnetic Semiconductor EuSc2Te4 With Magnetism‐Driven Nonlinear Transport

open access: yesAdvanced Functional Materials, EarlyView.
EuSc₂Te₄, an antiferromagnetic semiconductor, exhibits a nonlinear Hall effect (NLHE) characterized by quadratic current–voltage behavior. Combined experimental and theoretical studies reveal that this NLHE is linked to its antiferromagnetism and involves contributions from the quantum metric.

Financial fragility and the exchange rate regime [PDF]

open access: yes
We study financial fragility, exchange rate crises, and monetary policy in an open economy version of a Diamond-Dybvig model. The banking system, the exchange rate regime, and central bank credit policy are seen as parts of a mechanism intended to ...

Hyperbranched Interpenetrating Hydrogen Bond Network (HIHBN) Proton Exchange Membrane for Fuel Cells Above 220 °C

open access: yesAdvanced Functional Materials, EarlyView.
A novel polymer electrolyte membrane with a hyperbranched interpenetrating hydrogen bond network structure is developed. The unique structure of the hyperbranched polymer contributes to a high glass transition temperature exceeding 400 °C, enabling its operation at elevated temperatures for fuel cell applications.

Turning on Selective H2S Gas Sensing Activity in Ternary Nickel Tungstate Strongly Correlated Electron System Through Sub‐Gap Band Manipulation

open access: yesAdvanced Functional Materials, EarlyView.
A strongly correlated electron system (SCES) exhibits pronounced insulating behavior due to Coulombic repulsion between cations, which generates a charge gap. This study investigates the tuning of the band structure in NiWO4‐based SCES via Cu doping at substitutional sites and Li doping at interstitial sites.

A Role Model for China? Exchange Rate Flexibility and Monetary Policy in Japan [PDF]

open access: yes
Few papers have tried to project how Chinese monetary policy will behave under flexible exchange rates. As Japan provides an important role model for China, this paper studies the role of the yen/dollar exchange rate for Japanese monetary policy after ...

Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

A Framework for Exchange Rate Policy in Korea [PDF]

open access: yes
The monetary policy and exchange rate regime that served Korea well for many years ended in crisis in 1997. The regime that collapsed was characterized by a tightly managed nominal exchange rate and domestic financial markets that were controlled by the ...
