Chiral‐Encoded Pt‐Ir Surfaces as Apparent Spin Filter for Enhanced Oxygen Reduction

open access: yesAdvanced Science, EarlyView.
The Chiral‐Induced Spin Selectivity (CISS) effect is employed in chiral‐encoded mesoporous Platinum‐Iridium (Pt‐Ir) electrocatalysts to enhance the oxygen reduction reaction (ORR). A break in spin symmetry leads to a substantial antagonistic difference in activity (>200%) when comparing two enantiomorphs of the same electrode.

MIGRATION ANADROME ESTUARIENNE DES GÉNITEURS DE GRANDE ALOSE ALOSA ALOSA, ALLURE DU PHÉNOMÈNE ET INFLUENCE DU RYTHME DES MARÉES.

open access: yesKnowledge and Management of Aquatic Ecosystems, 2001
Pour accéder à leurs zones de frayères les géniteurs de grande alose Alosa alosa L. 1758, traversent un estuaire où, en fonction du rythme des marées, les conditions hydrauliques sont tantôt favorables tantôt défavorables à leurs déplacements.

Synchronization‐Dissipation in the Cardiorespiratory System

open access: yesAdvanced Science, EarlyView.
By modeling central nervous coupling and viscoelastic interactions in the cardiorespiratory system we show that synchronization produces a 10% gain in cardiac efficiency in humans. It is surmised that respiratory sinus arrhythmia improves cardiac pumping efficiency by reducing dynamic stress and power dissipation in the pulmonary vasculature.

Mechanisms of light harvesting complex proteins in photoprotection of the brown tide alga

open access: yesNature Communications
The propensity of Aureococcus anophagefferens to form harmful brown tide blooms has been linked to rapid light responses, but the underlying molecular mechanisms remain elusive.

‘Turning the Tide’

open access: yesApplied Phycology
‘Turning the Tide’ (2020–present) is the most recent project in my lifelong involvement with seaweed. I write about my use of photography and drawing to capture the fleeting existence of seaweed strewn along the tideline.

A Piezo‐Mimetic Ionic Hydrogel Harnessing Joint Motion for Cartilage Repair

open access: yesAdvanced Science, EarlyView.
A piezo‐mimetic ionic hydrogel converts mechanical deformation into bioactive ionic currents via stress‐induced asymmetric ion migration. Coupled with sustained Mg2+ release, this mechano‐electrochemical platform bridges mechanical loading and cellular signaling, enabling load‐adaptive stimulation and enhanced cartilage regeneration. ABSTRACT Articular

Selective Electrolysis of Water Under Artificial Seawater Conditions Using Transition Metal Borate Anodes

open access: yesAdvanced Energy Materials, EarlyView.
The borate‐based cobalt‐iron catalyst promotes selective oxidation of water rather than chlorine evolution reaction during electrolysis of seawater. When integrated into a zero‐gap electrolyzer prototype, this catalyst supports robust splitting of artificial seawater into oxygen and hydrogen on an extended timescale.

The Tide-Predicter [PDF]

open access: yesNature, 1881
MR. EDWARD ROBERTS' letter in NATURE for April 14 contains statements giving an erroneous view of the origin of the tide predicter. Any one who feels sufficient interest in the subject to derive full information will find it in my paper on “The Tide-Gauge, Tidal Harmonic Analyser, and Tide-Predicter,” read before the Institution of Civil Engineers on ...
