Characterizing Biopolymer Electrolytes in Zinc–Air Batteries: Challenges, Best Practices, and a Robust Workflow Guiding Future Research Paths

Advanced Energy Materials, EarlyView.
Bio‐based gel polymer electrolytes promise sustainable, mechanically adaptable zinc–air batteries, yet their progress is constrained by inconsistent characterization. This review critically links formulation, structure, interfaces, and cell performance, identifies methodological gaps under alkaline operating conditions, and proposes application ...

Transverse Spurious Mode Compensation for AlN Lamb Wave Resonators

IEEE Access, 2019
Lamb wave modes with type I dispersion characteristics exhibit strong affinity toward multi transverse modes behavior above resonance frequency (fr) in the AlN Lamb wave resonators (LWRs), especially the high-transduction-efficiency modes: S0 and S1 mode.

Localized 3D acoustic streaming in microdroplets using high‐frequency micro‐beam IDTs

Droplet, EarlyView.
Miniaturized 160 MHz acoustic microbeam transducers, with a size much smaller than droplets, enable precise localized actuation, generating complex three‐dimensional streaming and tunable particle aggregation. This concept provides high‐resolution, non‐contact fluid manipulation for biosensing, lab‐on‐chip diagnostics, and targeted drug screening ...

Ionospheric Lamb Waves With Conical Phase Fronts Following the 2022 Tonga Eruption Unveiled by BeiDou GEO Observations

Geophysical Research Letters
Prior observational uncertainties have hindered the clear understanding of the link between tropospheric Lamb waves and ionospheric disturbances. In this study, we precisely extracted ionospheric Lamb waves originating from the epicenter of the 15 ...

Brexit and Its Impact on EU Financial Markets

International Journal of Finance &Economics, EarlyView.
ABSTRACT We investigate the impact of Brexit on volatility spillovers across the EU countries. We introduce a Brexit intensity measure that assigns an intensity score reflective of the financial markets' reaction to the events that occurred as Brexit negotiations began to unfold.
