Lifetime of the Gas Evolution Electrode of the Zn–H2 Storage System
Fuel Cells, EarlyView.ABSTRACT A novel electrically chargeable galvanic system is presented that efficiently stores energy in the form of zinc and releases hydrogen and electricity upon discharge. In this concept, oxygen is released at the gas electrode during charging, and zinc oxide is reduced to metallic zinc at the counter electrode.

A tunable microwave absorption metamaterial inspired by moths evading bat detection
InfoMat, EarlyView.Electromagnetic radiation in the current environment has become complex and uncontrollable due to the advancement of wireless technology. Inspired by the moth surface cilia to bend and evade bat sonar detection, our work introduces a metamaterial incorporating broadband and tunable microwave absorption properties combined with deep learning algorithms.

Quantitative Mapping of Fibrotic Tissue Mechanics via Brillouin Spectroscopy
Journal of Biophotonics, EarlyView.Brillouin spectroscopy distinguishes fibrotic from healthy tissue based on localized stiffness changes and enables real‐time monitoring of dynamic alterations in viscoelastic properties during fibrogenesis. ABSTRACT Fibrosis is a pathological scarring process that disrupts tissue architecture, and is characterized by excessive extracellular matrix (ECM)

Effects of temporal and spatial variability in energy fluxes on phytoplankton
Limnology and Oceanography, EarlyView.Abstract Climate change has significantly altered the energy dynamics of lakes; however, little is known of how the temporal and spatial variation in energy fluxes impacts the structure and function of lake ecosystems. This study combined long‐term (2011–2018) measurements of lake energy fluxes with environmental, nutrient, and phytoplankton data at ...

Extreme wildfire conditions shift coastal phytoplankton community structure in California
Limnology and Oceanography, EarlyView.Abstract Extreme wildfires have increased in frequency and intensity globally, particularly in the Western United States. Here we examine how the 2020 Lightning Complex Fires in California influenced coastal phytoplankton communities using monitoring network data products in the Monterey Bay, the ocean region closest to this large fire.

Topological Engineering of High‐Order Exceptional Points Through Transformation Optics
Laser &Photonics Reviews, EarlyView.A novel framework leveraging transformation optics is introduced for engineering high‐order exceptional points (EPs) in nanophotonic systems. By linking these spectral singularities to physically accessible parameters, this approach enables the design of complex EPs, including third and fourth‐order EPs in coupled nanowire systems.

Customizing 3D Polarization Structures at Second Harmonic Frequency
Laser &Photonics Reviews, EarlyView.The nonlinear optical metasurfaces that can generate second harmonic waves (SHWs) and manipulate 3D polarization structures are designed and fabricated. Based on the concept of nonlinear geometric phase, the desired phase distributions of the SHWs are encoded onto the metasurfaces by using gold C3 meta‐atoms.
