Relationships between mountain pine and climate in the French Pyrenees (Font-Romeu) studied using the radiodensitometrical method

open access: yesPirineos: Revista de Ecología de Montaña, 1994
[es] Se ha llevado a cabo un trabajo densitométrico sobre 46 Pinus uncinata (Ramond) en Font-Romeu (Cerdaña francesa). Las funciones de correlación con el clima han sido calculadas sucesivamente con el espesor de los anillos de crecimiento, la densidad ...

Biomineral‐Inspired Organic/Inorganic Colloidal Liquid‐Crystalline Hybrids for Photoresponsive Adhesion

open access: yesAdvanced Functional Materials, EarlyView.
A new class of photoresponsive liquid‐crystalline (LC) adhesives based on biomineral‐inspired organic/inorganic colloidal hybrids is reported. These colloidal LC materials are formed by hybridization of a hydroxyapatite nanorod with azobenzene‐based forklike molecules.

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

An Edible Chitosan‐Based Acoustic Sensor for Sound‐Responsive Actuation in Edible Robots

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces an edible acoustic sensor for robotic food and edible robotics. Built from a chitosan piezoelectric film between gold electrodes, the sensor enables acoustic communication through ON/OFF keying. Integrated into an edible robot with pneumatically actuated arms and neck, it responds to high‐frequency tones.

A Fourier pseudospectral method for some computational aeroacoustics problems [PDF]

open access: yes, 2006
A Fourier pseudospectral time-domain method is applied to wave propagation problems pertinent to computational aeroacoustics. The original algorithm of the Fourier pseudospectral time-domain method works for periodical problems without the interaction ...

Cyst Detection in Toxoplasma gondii Infected Mice and Rats Brain

open access: yesBio-Protocol, 2015
Toxoplasmosis caused by the intracellular parasite Toxoplasma gondii, is characterized by a life-long chronic infection. The parasite is an efficient neurotropic infectious agent that establishes its “safe” life by forming intracellular cysts in ...
