Flood Pulse Design Principles—A Time-Based Approach to Urban Flooding

open access: yes, 2020
This chapter explores the potential of a time-based, nature-inspired approach to urban flood resilient design in the context of SeaCities. As a vast majority of existing coastal cities develop along continental shorelines and are in the proximity of rivers (accounting for freshwater supply, anchorage, etc.), coastal urban development is exposed to ...

Static Drainage H2/O2 PEM Fuel Cells Enabled by Water Transport Plates: Pore‐Scale Design and Transport Mechanisms

open access: yesAdvanced Science, EarlyView.
The WTP is a key component of static drainage PEMFCs, enabling cathode water removal and gas sealing through capillary forces. This work investigates the mechanisms governing WTP drainage and sealing performance and develops predictive approaches for WTP design optimization.

Unraveling the Effects of Depolarization in Ultrathin Barium Titanate

open access: yesAdvanced Science, EarlyView.
This article employs synchrotron‐based spectroscopy, time‐resolved electrical measurements, and phase‐field simulations to establish reverse‐domain formation as the mechanism of polarization loss in ultrathin BaTiO3${\rm BaTiO}_3$ films as a critical obstacle to low‐voltage ferroelectric devices.

Activation‐Induced Turbostratic Ordering in pDCPD‐Derived Hard Carbon Enables Stable Carbonate‐Based Sodium‐Ion Storage

open access: yesAdvanced Science, EarlyView.
Hard carbon derived from templated poly(dicyclopentadiene) as anode for sodium–ion batteries was engineered through carbonization and second‐step CO2${\rm CO}_2$ activation. High‐temperature carbonization and activation increased local ordering while reducing defects without inducing structural fracture.

Mississippi River-floodplain connectivity level mediates fish assemblage dynamics

open access: yesJournal of Limnology
The life histories of many Louisiana fishes are tied to the timing, magnitude, and duration of the Mississippi River flood pulse. Anthropogenic modifications designed to control and restrict flood waters have decoupled Louisiana’s floodplains from the ...

Oxygen‐Scavenging‐Driven Interlayer Engineering for Balancing Linearity and Retention in IGZO Synaptic Memristors

open access: yesAdvanced Electronic Materials, EarlyView.
Oxygen‐scavenging‐induced self‐formed interlayers regulate Schottky‐barrier modulation in IGZO memristors, producing a fundamental trade‐off between synaptic update linearity and retention. A preserved AlOx interlayer moderates voltage distribution and enables gradual, nearly linear conductance updates, whereas a soft‐broken SiO2 interlayer provides a ...

The floristic heterogeneity of the Pantanal and the occurrence of species with different adaptive strategies to water stress

open access: yesBrazilian Journal of Biology
The Pantanal is characterised by a diversity of environments with areas ranging from periodic or permanent heavy flooding to areas with low flood levels, and even environments that never flood.

Modulation of Local Environment for Selective Bicarbonate Conversion to Multi‐Carbon Products

open access: yesAdvanced Energy Materials, EarlyView.
Highly porous Cu electrode partially coated with an ionomer/carbon composite enables efficient conversion of bicarbonate to multi‐carbon products. By regulating the local reaction microenvironment, this strategy overcomes selectivity and reaction‐rate limitations, achieving Faradaic efficiencies of 43% for ethylene and 60% for total multi‐carbon ...
