RELATIONS PLANTE/SOL/CLIMAT Connaître le sol : nouveaux enjeux pour la gestion des territoires ruraux

open access: yesOléagineux, Corps gras, Lipides, 2000
Dans son acception commune, le mot sol désigne de façon souvent indissociable l’espace d’un territoire et la terre qui le recouvre. Cet héritage culturel d’une époque encore proche où l’association territoire-espace rural-agriculture relevait de l ...

Contribution of integrated farm management (IFM) to Defra objectives [PDF]

open access: yes, 2009
A farming system comprises a complex of interrelated and interacting factors. Any study of an isolated part of the system will not provide adequate understanding of the behaviour of the entire system and interactions may be equally or more important than

Prospects of Electric Field Control in Perpendicular Magnetic Tunnel Junctions and Emerging 2D Spintronics for Ultralow Energy Memory and Logic Devices

open access: yesAdvanced Functional Materials, EarlyView.
Electric control of magnetic tunnel junctions offers a path to drastically reduce the energy requirements of the device. Electric field control of magnetization can be realized in a multitude of ways. These mechanisms can be integrated into existing spintronic devices to further reduce the operational energy.

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

open access: yesAdvanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Multicolor Optoelectronic Synapse Enabled by Photon‐Modulated Remote Doping in Solution‐Processed Van Der Waals Heterostructures

open access: yesAdvanced Functional Materials, EarlyView.
Multicolor optoelectronic synapses are realized by vertically integrating solution‐processed MoS2 thin‐film and SWCNT. The electronically disconnected but interactive MoS2 enables photon‐modulated remote doping, producing a bi‐directional photoresponse.

Mise en oeuvre de la théorie de la percolation pour modéliser le drainage des milieux poreux et la perméabilité relative au liquide non mouillant injecté Application of the Percolation Theory for the Simulation of Penetration Into Porous Media of a Non Wetting Fluid and the Prediction of the Relative Permeability Curve

open access: yesOil & Gas Science and Technology, 2006
Pour comprendre les phénomènes physiques ayant lieu au sein des milieux poreux, il est nécessaire d'arriver à un modèle géométrique qui est représentatif du milieu, et qui permet de calculer ses propriétés.

Wafer‐Scale Synthesis of Mithrene and its Application in UV Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
A controlled tarnishing step on the silver surface precedes the solid‐vapor‐phase chemical transformation into silver phenylselenolate thin films. The approach yields crystals exceeding 1 µm with improved in‐plane orientation. Integration on graphene phototransistors demonstrates high photoresponsivity, positioning mithrene as a promising material for ...
