AFM : Atomic Force Microscopy (6h) – Christophe Tromas

Monday March 28, 9 a.m.-12 p.m. and 2 p.m.-5 p.m.

This seminary aims at presenting the Scanning Probe Microscopy (SPM) techniques, and more specifically the Atomic Force Microscopy (AFM). AFM is a surface microscopy technique which consists in scanning a surface with a nanometer size tip while monitoring the interactions between the tip and the surface. The signal is then processed to reconstruct a 3D image of the surface topography, at scales ranging from 100 µm down to atomic resolution.

Contenu pédagogique / teaching content :

• Introduction et historique / Introduction and history of SPM
• Microscopie à effet tunnel / Scanning Tunneling Microscopy
• Le mode contact / Microscopie Atomic Force microscopy in contact mode
• Le mode dynamique / Atomic Force Microscopy in dynamic mode
• Pointes et scanner / AFM probes and scanners
• Image et analyse / AFM image processing and analysis
• Au-delà de l’imagerie topographie / AFM – beyond topographic imaging
• Applications/ Applications of AFM (academic lab, industry)
• Le microscope / Practicals: Atomic resolution in STM, AFM settings

WFTMT : Wall and Fluid Temperature Measurement Techniques (6h.) – Gildas Lazilel

29th March, 9 a.m.-12 p.m. and 2 p.m.-5 p.m.

This seminary consists to study different existing or in development techniques to precisely measure temperature in fluids (laminar or turbulent flow) or in solid (wall or inside). Intrusive (thermocouples, cold wire, …) and non-intrusive techniques will be presented (Pyrometry, Infrared camera, Laser Induced Fluorescence or Phosphorescence). Physical concepts associated to each metrology will be presented / Ce séminaire consiste à étudier différentes techniques existantes ou en développement pour mesurer précisément la température dans les fluides (écoulement laminaire ou turbulent) ou dans le solide (mur ou intérieur). Des techniques intrusives (thermocouples, fil froid, …) et non intrusives seront présentées (Pyrométrie, Caméra Infrarouge, Laser Induced Fluorescence ou Phosphorescence). Les concepts physiques associés à chaque métrologie seront présentés.

Contenu pédagogique / teaching content :

• Introduction au transfert de chaleur : conduction, convection et rayonnement thermique / Introduction to heat transfer : Conductive, convective and Radiative heat.
