A Nikon Eclipse TE2000-U inverted microscope with excitation and detection hardware and electronics to perform single-particle spectroscopy and blinking measurements. In addition, this microscope has been integrated via fiber coupling and electronics with the MSF’s existing Edinburgh FLS1000 fluorometer. This integrated configuration allows users to obtain spatially resolved spectroscopic information about luminescent samples. The combination of a Xenon white light source and multiple lasers in the excitation path enables users to carry out wide-field and confocal microscopy experiments.

Nine MEM-C computing nodes have been recently acquired and added to the MSF’s offerings. This new shared facility, integrated in the UW Hyak high-performance computing (HPC) ecosystem, supports computational materials science and data science research within MEM-C and in the broader materials science research community. This resource is accessible to all UW researchers through UW Hyak’s “checkpoint” access system, where other users can identify and access idle nodes across the cluster. UW Hyak HPC also provides computer hours to the national Open Science Grid (OSG). Training is provided through the UW eScience Software Carpentry program and computational science courses including the Computational Chemistry, Materials and Device Modeling, and Nanotechnology Modeling classes.

The NanoITC is a state-of-the-art isothermal titration calorimeter (ITC) that is designed to handle large sample volumes while maintaining a small instrument footprint and allows thermodynamic measurements on systems like nanocrystal doping and surface-binding reactions. The ITC can measure reactions in organic solvents as well as under inert atmosphere. The instrument has extremely high sensitivity and can measure heat down to 0.1uJ with minimum noise. The instrument accommodates a large sample volume of 1.6mL and allows for two different volumes of titrant to be used.
Capabilities
- Designed to perform high-sensitivity analyses on nanomolar quantities of analytes
- Accurate and stable temperature control and efficient titrant control
- Vacuum-tight chamber isolates reaction cells from room temperature fluctuations
- Integrated, flexible titration assembly ensures quick, easy filling, simple cleaning and accurate titrations

Status note December 2022: The PLD is out-of-service at this time. Please check back for updates on its status or contact the superuser for more information.
Pulsed laser deposition (PLD) is a laser-based technique used to grow high-quality thin films of complex materials on substrates like Silicon wafers. The material to be deposited (target) is vaporized by short and intense laser pulses and forms a plasma plume. Then, the vaporized target material from the plasma bombards the substrate and creates a thin homogenous layer on this substrate. For each laser shot, a layer of only a few nanometers of material is ablated to form the plasma plume in a process that typically lasts a few tens of picoseconds. To enable this process, nanosecond pulses from a fully contained excimer laser with energies of tens to hundreds of mJ are necessary.
Capabilities
- Precise deposition of chalcogenide monolayers from bulk chalcogenide targets
- High vacuum sample chamber for high purity deposition conditions

The Discover SP Microwave synthesizer (CEM) allows for rapid heating of solvents up to 300 °C and pressures up to 300 psi. Reaction vessels can be prepared in a glovebox and will maintain inert environment while capped allowing for air free synthesis. Reaction conditions are monitored over time through software and can be saved for comparison between syntheses. Reactions are rapidly cooled down following synthesis by flowing compressed air around the reaction vessel. The system is also equipped with an autosampler accessory that enables automatic handling of reaction vessels allowing for different experiments to be programmed and performed automatically.
Capabilities
- Large, single-mode microwave cavity (uses glassware up to 35 mL, pressurized; 125 mL, open vessel round bottom flask) Activent® vent and re-seal technology allows for safe handling of over-pressurization
- Highly accurate infrared temperature control for reliable data
- Variable-speed magnetic stirring
- Rapid compressed air cooling for quick cool-downs

This custom XES instrument consists of two independent, integrated spectrometers simultaneously measuring phosphorus Kα and Kβ XES. While the Kα XES gives information on oxidation state distribution, the Kβ XES gives additional information about electronic structure, including sensitivities such as ligand identity, symmetry, and bonding information. This dual capability system allows measurement of both of these channels for maximum information content of each sample.
Capabilities
- Glovebox integration enables measurement of air and water sensitive samples
- Simultaneous measurement of phosphorus Kα and Kβ emission regions
- Automated sample chamber for measurement of up to 15 samples with minimal effort
