NanoTools Facility

The NanoTools facility comprises sophisticated characterization instrumentation, and it serves the research and teaching needs of faculty, researchers, and students in the physical and biological sciences at Brown University.  It is also available for use by outside academic and industry users.  The current state-of-the-art NanoTools instrumentation consists of:

Asylum MFP-3D Origin AFM 

The Asylum MFP-3D Origin AFM is forcharacterization of surface topology,  materials research, including magnetic force microscopy, conductive AFM, and viscoelastic mapping.

Bruker D8 Discover X-ray Diffraction System 1

The Bruker D8 Discover X-ray Diffraction System includes reflectometry, high-resolution diffraction
in-plane grazing incidence diffraction (IP-GID), as well as residual stress and texture investigations.  One of the systems has the tube configured as a point focus, with a poly-cap optic, and a Vantec-500 area detector. This system is used mostly for powder diffraction, stress, and texture measurements. 

Bruker D8 Discover X-ray Diffraction System 2

The second system is in a line focus, and can either be run in a Bragg-Brentano set-up, or as a parallel beam using a Gobel mirror. This arrangement is better for X-Ray Reflectropmetry (XRR), High resolution diffraction, as well as grazing incidence diffraction (GI-XRD) 


Bruker EMXPlus Electron Paramagnetic Resonance (EPR) Spectrometer

The  Bruker EMXPlus Electron Paramagnetic Resonance (EPR) Spectrometer is for the detection and identification of free radicals in biological systems and nanotoxicology studies. The technique specification includes 24 bit center field resolution with a precision of less than 1 mG, up to 256,000 points for field sweep, full freedom in magnetic field sweep from 100 mG up to the maximum field and dual channel, simultaneous detection of 1st and 2nd harmonics.  

Park Scientific XE-Bio AFM and ICM (Ion Conductance Microscope) 

The Park Scientific XE-Bio AFM and ICM (Ion Conductance Microscope) is for biological research. ICM is capable of imaging cells alive in liquid with minimum damage to the cells.

Witec alpha 300M+ Confocal Raman Microscope.

The Witec alpha 300M+ Confocal Raman Microscope acquires local Raman spectra and distribution of different phases within a sample. The Alpha300M+ is used in the determination of carbon structures and vibrational molecular signatures. Capable of imaging stacking and 3 D imaging and depth profiling. The depth profiling and 3D imaging capabilities of the alpha300 R provide the ability to analyze the interior of transparent samples without microtome sectioning or freeze etching.
