Évolution des stocks de carbone en fonction des trajectoires de gestion en zone humide

open access: yesSciences, Eaux & Territoires, 2018
Plans de gestion et études d'impact devraient dorénavant inclure les services écosystémiques (SE). Face au changement climatique, la régulation du climat global par le stockage de carbone par les écosystèmes est un SE au cœur des préoccupations. C'est un

Thermally Induced Fluctuations Below the Onset of Rayleigh-B\'enard Convection

open access: yes, 1995
We report quantitative experimental results for the intensity of noise-induced fluctuations below the critical temperature difference $\Delta T_c$ for Rayleigh-B\'enard convection.

In Situ 3D Bioprinting: Impact of Cross‐Linking on the Adhesive Properties of Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
In situ 3D bioprinting enables the direct deposition of cell‐laden, adhesive biomaterials for on‐site tissue regeneration. This review provides a comprehensive overview of how cross‐linking influences the bioadhesive properties of hydrogels used in 3D bioprinting, highlighting cross‐linking triggers, bioadhesion mechanisms, polymer interpenetration ...

Le changement climatique, un défi pour la recherche : l’exemple de l’initiative « 4 ‰ »

open access: yesOilseeds and fats, crops and lipids, 2017
L’agriculture, l’activité humaine probablement la plus dépendante du climat, est à la fois victime et responsable du changement climatique mais elle peut aussi être une solution à la crise du changement climatique.

Les sols de jardins, supports d’une agriculture urbaine intensive

open access: yesVertigO, 2012
Vegetable gardens are localised in human impacted environments, at the interface between agriculture, city and industry. Therefore, garden soils are highly fertile and show very contrasted characteristics resulting from various gardening practices. These

Solitons in anharmonic chains with ultra-long-range interatomic interactions

open access: yes, 1999
We study the influence of long-range interatomic interactions on the properties of supersonic pulse solitons in anharmonic chains. We show that in the case of ultra-long-range (e.g., screened Coulomb) interactions three different types of pulse solitons ...

Trifluoromethoxylated Electron Acceptor Enabling Ternary Organic Solar Cells with over 20% Power Conversion Efficiency

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT In this work, we introduce a trifluoromethoxy (OCF3) group as a pseudo‐halogen terminal group design for non‐fullerene acceptors, which combines strong inductive electron‐withdrawing ability with moderate resonance donation. The as‐synthesized BTP‐OCF3, when benchmarked against its methoxy analogue BTP‐OCH3, demonstrates narrowed bandgap ...

Scenarios of domain pattern formation in a reaction-diffusion system

open access: yes, 1996
We performed an extensive numerical study of a two-dimensional reaction-diffusion system of the activator-inhibitor type in which domain patterns can form.

Synergistic All‐in‐One Electroceutical Platform Utilizing a Plasma–Photodynamic Hybrid Approach for Enhanced Wound Healing

open access: yesAdvanced Functional Materials, EarlyView.
A flexible hybrid patch integrating a robust cold atmospheric plasma (CAP) system with a high‐power, ultrathin bio‐OLED was developed to enable synergistic wound healing. This multimodal therapy, combining plasma and photodynamic treatment, enhanced angiogenesis, cell proliferation, and collagen deposition, demonstrating superior in vivo efficacy and ...
