Engineered Interpenetrating MXene Networks in Aramid Layered Films for Antioxidant and Broadband Electromagnetic Interference Shielding

open access: yesAdvanced Science, EarlyView.
This study introduces an innovative interpenetrating layered structure, comprising alternating aramid nanofiber (ANF) layers and MXene layers, fabricated through a directional freeze–thaw intercalation–gel‐film formation strategy. Unlike traditional homogeneous layered films, this unique layered structure features mutually embedded conductive and ...

"The Dismal State of Macroeconomics and the Opportunity for a New Beginning" [PDF]

open access: yes
The Queen of England famously asked her economic advisers why none of them had seen "it" (the global financial crisis) coming. Obviously, the answer is complex, but it must include reference to the evolution of macroeconomic theory over the postwar ...

Two‐Dimensional La2CoO4 Perovskite Oxide Enabled by Phonon‐Resonance‐Driven Exfoliation for High‐Performance Gas Sensing

open access: yesAdvanced Science, EarlyView.
Few‐layer La2CoO4 nanosheets are produced via phonon‐resonance‐assisted cleavage of the rock‐salt layers in the Ruddlesden‐Popper structure under the 20 kHz resonance condition, enabling controlled exfoliation into ultrathin sheets. The nanosheets show improved gas‐sensing capability, delivering an 86.67% response to 1 ppm NO2 at room temperature ...

The Internal‐External Synergy of Self‐Reconstructed C/NiFeOOH/SeO42− for Efficient and Stable Seawater Electrolysis

open access: yesAdvanced Science, EarlyView.
This work presents an internal‐external synergy strategy where a C@FeNi2Se4 core‐shell precursor reconstructes in to a C/FeNi2Se4/SeO42− architecture during OER. The inner C stabilizes active sites while the outer SeO42− layer repels Cl−, achieving efficient and stable seawater oxidation for over 150 h at 400 mA cm−2.

Impact of Processing Environment on Anti‐Solvent Free FAPbI3 Films and Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
This work explores the dependence of 2‐step FAPbI3 films and solar cells on the atmosphere and humidity during each processing step. In‐situ and ex‐situ characterizations are used to correlate film composition, structure, morphology, and intermediate phase evolution with solar cell performance and lifetime.

A re-visit to Minsky after 2007 financial meltdown

open access: yes, 2011
The 2007 financial crises has brought to eminence and a long overdue recognition to the ideas of Hyman P. Minsky who is a post-Keynesian authority on monetary theory and financial institutions.
