Developmental dynamics of cone photoreceptors in the eel [PDF]

open access: yes, 2009
Background: Many fish alter their expressed visual pigments during development. The number of retinal opsins expressed and their type is normally related to the environment in which they live.

Reconfigurable Ferroelectric‐Like Two‐Dimensional Electron Gas at Room Temperature

open access: yesAdvanced Materials, EarlyView.
We demonstrate the realization of a novel ferroelectric‐like two‐dimensional electron gas (2DEG) based on the epitaxial interface between SrO‐terminate SrTiO3 and ferroeletric KNb0.5Na0.5O3${\rm KNb}_{0.5}{\rm Na}_{0.5}{\rm O}_3$ thin films. We show nonvolatile control of the transport properties enabling spatially reconfigurable devices in which ...

Establishing Atomic Coherence in Twisted Oxide Membranes Containing Volatile Elements

open access: yesAdvanced Materials, EarlyView.
Twisted oxide membranes containing volatile elements often suffer from amorphous interfacial dead layers that suppress coupling. An oxygen‐annealing strategy establishes atomically coherent and chemically bonded interfaces in twisted NaNbO3 membranes, enabling coherent oxide moiré architectures in volatile‐element‐containing systems.

Simulated effects of hydroelectric project regulation on mortality of American eels

open access: yes, 2003
American Fisheries Society Symposium 33We used six years of silver-phase American eel Anguilla rostrata catch data from a weir on a Maine river to determine if river flow and rainfall were predictive of eel migration timing and simulate operational ...

Bifunctional Catalysis Drives Efficient and Ethanol‐Producing Aqueous Zn‐CO2 Batteries

open access: yesAdvanced Materials, EarlyView.
A unified bifunctional catalyst breaks the trade‐off between CO2 reduction and O2 evolution, delivering high efficiency, ethanol production, and long‐term stability in Zn‐CO2 batteries while revealing degradation pathways for next‐generation bifunctional electrocatalysts.

Controlled Synthesis of Tri‐ and Multi‐Doped Graphene

open access: yesAdvanced Materials Interfaces, EarlyView.
This review systematically evaluates synthesis routes for tri‐ and multi‐doped graphene, from hydrothermal and pyrolysis methods to flash Joule heating, critically assessing how each governs dopant incorporation, bonding configuration, and resulting electronic properties.

Migratory pattern and habitat use of tropical eels Anguilla spp. (Teleostei : Anguilliformes : Anguillidae) in the Philippines, as revealed by otolith microchemistry

open access: yes, 2010
To determine the migratory pattern and habitat use of freshwater eels in the Philippines, we analyzed the strontium to calcium (Sr:Ca) ratio of their otoliths with the use of an electron probe microanalyzer (EPMA). The changes in the otolith Sr:Ca ratios

Advanced MXene‐Based Multifunctional Nanoarchitecture Materials Engineered for Adsorptive Cleanup of Hazardous Radioactive Pollutants: A Comprehensive Critical Review

open access: yesAdvanced Materials Interfaces, EarlyView.
This work critically reviews MXenes as highly effective multifunctional nanomaterials for the adsorption of radio‐contaminants, demonstrating a remarkable adsorption capacity of up to 1376.75 mg/g and cyclic stability of 2–8 cycles, with complexation, electrostatic interactions, and the numerical strength of MXene active sites playing a key operational

Differential timing of gene expression regulation between leptocephali of the two Anguilla eel species in the Sargasso Sea [PDF]

open access: yes, 2011
The unique life-history characteristics of North Atlantic catadromous eels have long intrigued evolutionary biologists, especially with respect to mechanisms that could explain their persistence as two ecologically very similar but reproductively and ...

Metal Ion‐Induced Fast Gelation of 2D MnO2 Nanosheets With Cationic Vacancies for Durable Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
We report Mn‐deficient aerogels by inducing the first gelation of MnO2 nanosheets in solution using divalent metal ions as crosslinking agents, thereby inhibiting nanosheet restacking and enhancing surface utilization. Benefiting from abundant Mn vacancies and 3D porous structures, the A‐MnO2 cathode exhibits improved conductivity, fast reaction ...
