Abstract:
Many experiments in scanning / transmission electron microscopy (S/TEM) collect an enormous amount of data, due to the widespread adoption of high speed direct electron detectors. These include in situ time series, tilt series for 3D tomography, spectroscopy data such as STEM-EELS, and four dimensional STEM (4D-STEM) diffraction experiments. As a result, we require fast and efficient software codes to analyze these large datasets. This workshop will provide an overview of open source python tools for analysis of atomic resolution imaging, spectroscopic, and diffraction datasets. In this workshop, we will direct participants through hands-on python tutorials and provide example datasets for analysis of 4D-STEM experiments using py4DSTEM. We will also explain the principles behind simulation of TEM and STEM experiments, and lead participants through tutorials of the abTEM and Prismatic simulation programs.

Abstract: In today's rapidly evolving research landscape, effective imaging data management is no longer just an option—it's a necessity. As cameras and imaging technologies advance, they generate increasingly large volumes of data, making robust data management systems critical. This need is particularly pronounced in large, multi-user facilities such as the Centre for Microscopy and Microanalysis (CMM) at the University of Queensland.

This workshop is designed to provide participants with a comprehensive understanding of how CMM addresses these challenges through an integrated data management approach. The workshop will explore the vision behind CMM's data strategy, which aims to empower researchers by ensuring that their data is not only stored securely but also remains easily accessible, interoperable, and reusable across various research projects.

The workshop will cover the following three key components:

1.    UQ Research Data Management (RDM) System: This system is the cornerstone of CMM's data storage strategy, offering scalable and secure data storage services that cater to the growing needs of modern research.

2.    Clowder Data Management Framework: A pivotal tool for data cataloguing, metadata extraction, and facilitating user access, Clowder ensures that researchers can efficiently manage and locate their data, significantly enhancing the productivity of multi-disciplinary research teams.

3.    Pitschi Platform: This platform plays a critical role in integrating imaging instruments with the RDM, Clowder, and the UQ Research Infrastructure Management System (RIMS). It streamlines processes such as booking validation, data capture, and seamless data transfer, ensuring that research workflows are both efficient and error-free.

This comprehensive solution adheres to the FAIR (Findable, Accessible, Interoperable, Re-usable) principles, which are increasingly being recognized as the gold standard in research data management. By aligning with these principles, the workshop aims to equip participants with the knowledge and tools necessary to make their data practices more sustainable and impactful. The workshop format includes lecture material presentations, discussions, and demonstrations.

Abstract: Transition to the carbon-free economy based on renewable energy generation and storage requires many metallic elements, including cobalt, lithium, copper, nickel, manganese, gallium, germanium, hafnium, indium, tantalum, titanium, vanadium, tungsten, platinum group metals, and rare earth elements. Reduction in the quality of ores coupled with an increased demand puts pressure on improving traditional methods of extractive metallurgy from natural minerals and stimulates development of secondary mining sources (industrial and domestic waste, manufacturing byproducts, mine tailings). Chemical analysis and mineral identification play a critical role on all the stages of metal life cycle, from the geological exploration to waste recycling. In this workshop the authors will share their views and experience in application of microscopy and microanalysis for automatic characterisation of minerals. In particular, recent developments in SEM-EDS, XRF, and LIBS based techniques will be discussed.

Abstract:
Lithium based compounds, from minerals (i.e. Spodumene [LiAlSi2O6]) to advance materials such as Aerospace Alloys [e.g. Al(Li)] and Lithium-Ion Batteries [e.g., (LiFePO4)] are certainly among the most difficult materials to detect and quantify in the electron microscope. While it is easier to detect lithium with ion beams it remains a challenge to quantify Li concentrations. This workshop aims to introduce various imaging related techniques from the detection to the quantification of Li, with emphasis on the workflow related to vacuum/argon handling and transfer of some of these air sensitive materials.

This workshop will cover these techniques:

• Windowless EDS systems in the SEM (e.g. Ultim Extreme Detector and Gather-X) the use of the Soft X-Ray Energy Spectrometer (SXES) in the EPMA

• Imaging SIMS (NanoSIMS and TOF-SIMS)

• EELS in the STEM at 30 keV and 200 keV.

All these techniques are critical for the characterisation and development of lithium-based metals for aerospace industry and materials including advance battery materials critically needed for the decarbonization of transportation vehicles together.

Abstract: Ultramicrotomy is the ultimate preparation method for polymers which shall be investigated in the TEM, SEM or in the AFM. Polymer materials have a wide variety in size, shape and physical/chemical state. Information is needed to perform successful ultramicrotomy: the polymer type, the glass transition temperature (Tg), is it a blend, a composite, the processing (injection, compression, extruded, etc), are there additives, fibres, nanoparticles, etc. Polymer samples are microtomed at room- or at cryo temperatures, according to their glass transition temperature. Less compression and hence a better structure preservation is achieved by reducing the wedge angle of the knife from 45° to 35° or even to 25° [1]. However, reducing the wedge angle leads to a more sensitive cutting edge. An alternative is to oscillate the knife [2]. This approach allows compression reduction and improved structure preservation in fairly rigid polymers [3, 4]. The oscillating knife reduces the compression almost completely without additional cutting artifacts. For achieving high quality sections the polymer samples need to be trimmed. This is best performed with diamond trimming blades.

Ultramicrotomy of polymers may be performed on a dry diamond knife, or with a liquid such as a dimethyl-sulfoxide/water mixture (50/50%). The temperature of the is kept at -40°C, the temperature for the sample remains below the glass transition temperature. 

Polymers show no or little contrast in the TEM and therefore need to be stained. Common staining agents are OsO4 or RuO4. Staining is performed on the sections or on the sample block after trimming. Blends may need double staining for expressing the different phases. In this case one starts with the weaker staining agent which is OsO4. For investigating nanoparticles, nanotubes or other inclusions no staining is needed.

For achieving a smooth surface for AFM investigation, the section thickness must be kept as thin as possible (<100nm). Sections in the micron range would not result in a smooth surface. It is crucial to distinguish a true structure and a sectioning artifact.  

For the ultrathin sectioning of metals very small sample blocks (width <50µm) are trimmed. Trimming is performed with diamond trimming blades, trimming machines, polishing, etc. Trimming is crucial for not causing damage to the rather soft metals.

The section thickness for metals is 20-40nm. Some metals such as iron, cobalt, nickel and others affect diamond chemically. This leads to a fast worn out of the cutting edge portion and hence to dislocations in the metal structure. For these metals one needs to change to a fresh knife portion after each section. Metals do not need embedding, unless they are thin foils or powders. Metallic coatings on brittle substrates may be processed without embedding [5]. Ultramicrotomy serves for generating high quality metal surfaces for SEM/EBSD investigation [6].

Ultramicrotomy of brittle Materials Research samples is an alternative to the established preparation technique such as polishing, focused ion beam cutting (FIB), ion thinning, cleavage or others. Advantages of ultramicrotomy are: fast, clean, no smearing (as from polishing), no beam damage (as from ion beam techniques). Disadvantages of ultramicrotomy: brittle materials break into small fragments during the cutting. On big samples finding the location of interest may be difficult. Precise target trimming may be performed by using a special target trimming machine. These machines allow first cutting the sample with a diamond saw, then grinding and polishing to size of a few microns, suitable for ultramicrotomy (Reference Ranner?).

Brittle material samples are embedded prior to ultramicrotomy in a rigid epoxi resin [7, 8, 9, 10). If a sample is resin embedded, sections with a thickness of 35nm may be achieved.  For sectioning hard samples such as ceramics, semiconductors, oxides, crystals, etc, a cross section must be small.(<20µm). Instead of embedding brittle samples may be glued on a support with cyanacrylate glue, or clamped in an AFM sample holder. Non embedded brittle samples may be sectioned as thin as 15nm.

For achieving a smooth surface for AFM investigation, the section thickness must be thin (<30nm). Cutting thicker results in a surface pattern. For brittle samples it is crucial to image a smooth surface, rather than a pattern caused by the cutting process.

Most brittle materials may be sectioned with 35° diamond knives. However, for some hard materials such as hydroxyapatite, olivin and some ceramics it was found that 45° diamond knives perform best.

Experience Level: CryoEM users looking to expand into advanced workflows

Abstract: This 2-day workshop will introduce an advanced cryoEM workflow starting from correlative cryogenic-focused ion beam (cryo-FIB) lamella specimen preparation all the way to cryo-tomography of the prepared lamella. The workshop is aimed at users with some cryogenic electron microscopy background who are looking into understanding the main concepts of cryo-FIB and cryo-tomography and would like to expand their capabilities into these two cryo-EM techniques.

The first day will include a demonstration of work on the Enzel system. The Enzel allows the preparation of cryo-FIB lamellae, while monitoring the fluorescent signal in an ROI, thus, allowing for a more accurate milling in the Z-axis. We will demonstrate the abilities of Enzel on a cellular sample, while targeting specific fluorescently labelled ROIs.

The milled lamellae prepared on the Enzel, will be transferred and loaded onto UQ’s newly arrived Thermo-Fisher Glacios. Utilizing its dedicated tomography software we will collect tilt-series tomograms in batch mode. In this cryo-tomography demonstration we will also apply a correlative approach, targeting the specific locations that were identified during the specimen preparation stage with the Enzel.

The workshop will be accompanied with introductory presentations about cryoFIB, Enzel and cryo-Tomography.

As space in both labs is quite limited, the number of participants in the workshop will be limited to 5 only.

Techniques:

• Correlative Cryo-FIBSEM sample preparation

• Correlative Cryo-Tomography
