Exploring flatlands: characterizing 2D materials with atomic force microscopy
The atomic force microscope (AFM) has played an essential role in 2D materials research since it was used to confirm the first isolation of graphene. Today’s AFMs are even more powerful, with higher spatial resolution, faster imaging rates, greater environmental control and enhanced modes for mapping physical properties. They can image crystal lattice structure as well as nanoscale morphology, and sense local electrical, mechanical and functional response in more ways than ever before.
In this webinar we explore the latest AFM tools that enable higher resolution, sensitivity and more quantitative results for analysing 2D materials. We’ll present results from measurements of a variety of 2D materials for device manufacturing, energy storage and optoelectronics including:
• MoS2 and graphene;
• measurements of mechanical properties;
• kelvin probe imaging (KPFM) of operating transistors;
• electromechanical measurements.
Finally, we discuss how AFM can now be used to accurately determine the thickness of single or multiple layers of a 2D material. This will challenge the misconception that AFM cannot be used to precisely measure the thickness of 2D materials.

The increasing number of diagnoses of brain metastases in asymptomatic patients – as a result of screening MRIs – has created the need for both durable control and prevention of cognitive decline in patients who are expected to have increasing median survivals. Since the mainstay of their therapy is systemic management, “Radiosurgery Now” represents the idea of immediate radiosurgery with the intent of avoiding interruption of systemic management.
This webinar will discuss the impact of delay in radiosurgery on tumour growth and the benefits of repeat radiosurgery for the long-term preservation of cognitive function. The linear and robust rapid workflow of the Leksell Gamma Knife® Icon™ is ideally suited to this concept.

A new class of radiation devices is emerging, and it has the potential to transform how cancer is treated through more precise tumor targeting and adapting treatment at the time of delivery. High-field MR-linac technology integrates the power of state-of-the-art MR imaging with precision radiation technology. It can deliver precisely-targeted radiation doses while simultaneously capturing the highest-quality MR images. This will allow clinicians to visualize tumors and the surrounding healthy tissue at any time during radiation delivery, and then adapt the treatment accordingly.
High-field MR-linac devices based on diagnostic-standard MRI technology will offer many avenues for exploring improvements in radiotherapy, such as shorter treatment regimens or targeted adaption of the treatment in real time. Also, by integrating precision radiation and MRI technologies, high-field MRI capabilities can be optimally explored to help bring personalized cancer care to radiation therapy.
During this webinar, clinical experts will share their experience with Elekta Unity.
The webinar, aimed at early career researchers, will cover a range of topics including how to choose the right journal, peer-review and publication ethics, and your open access publishing options thanks to funding agreements in Austria.
Jordan Moering, Protochips and Ray Unocic, Oak Ridge National Lab
As the imaging and analytical capabilities of the modern transmission electron microscope (TEM) have improved, it has become an increasingly vital tool to characterize and study nanoscale materials. With the advent of MEMS-based sample supports, researchers are now capable of easily heating and electrically characterizing their sample in situ, directly imaging the dynamic sample reactions occurring at the atomic scale.
For semiconductor and electrical device applications, Protochips has developed focused ion beam (FIB) tools and sample preparation workflows that enable researchers to prepare FIB lamellae directly on MEMS-based sample supports, allowing pA-level electrical characterization of their sample at atomic resolution. With the growing interest surrounding graphene and other 2D materials, in situ TEM has become increasingly utilized to accelerate the discovery of these next-generation materials. At Oak Ridge National Laboratory, researchers Xiahan Sang and Ray Unocic used in situ heating to synthesize and characterize complex structural and chemical transformations of edge defects at atomic resolution. Their work pioneered new means by which 2D materials could be engineered directly in the TEM, opening new avenues for materials development and characterization. These and other novel results in the field of material science will be presented in this webinar.

English is the lingua franca for scholarly communication, and most international journals with a wide global readership are printed in English. Submitting manuscripts in poor English can put researchers at a disadvantage and delay the publication of research. This session will highlight the importance of quality English writing and the need to communicate your research effectively. This session will also focus on understanding journals and the types of manuscripts they publish, so that you can identify the best type of article for your study.
Susanna Eriksson, Head of Product Management Electron Spectroscopy
During the past decade, increased attention has been shown to hard X-rays in the photoelectron spectroscopy (HAXPES) field. This is mainly due to the increased information depth enabled by the higher photon energies. Such bulk sensitive measurements could previously only be performed at dedicated synchrotron radiation facilities. The beam lines providing this type of radiation are heavily booked, so access to the experimental setups is thus limited. Higher excitation energies also enables bulk sensitive measurements of deep core levels not accessible with standard XPS.
We will present a new system featuring a monochromized X-ray source giving out Ga Ka radiation at 9.25keV and a wide acceptance angle hemispherical electron analyzer, both combined on a simple to use vacuum system. With this system, a new set of possible experiments opens up in the home laboratory: investigations of buried interfaces, in operando devices, real world samples, etc.
Join us for this 45 minute webinar with the author of Sun Protection: A risk management approach, Professor Brian Diffey. Professor Diffey will give an overview of his book, key learning points and answer your questions in a live Q&A.
About the book
Sun Protection differentiates itself from other texts by adopting a risk-management approach to determine whether, how, and in what circumstances, harm might be caused, and to explore the feasibility of various strategies in controlling exposure to solar UV radiation. This multi-disciplinary book covers topics from climatology through human exposure to sunlight, as well as biological and clinical effects of UV radiation to physical and chemical strategies for photoprotection.
This webinar is recommended viewing for biologists and dermatologists and will be of interest to physical scientists and those working in the skin care industry.

There has been, until now, no compelling evidence for biology beyond the confines of our own planet. And yet, people who investigate this topic feel confident that – within two decades – we will trip across life forms that are not, and never have been, earthlings. Why are they so optimistic that we will soon find some cosmic confrères, and what might be the implications of such a discovery?
Robyn Pritchard, Consultant Physicist The Technology Partnership (TTP) and Andrew Young, Technical Manager COMSOL
If you are interested in using simulation to enhance the development of a microfluidic device, then tune into this webinar with Robyn Pritchard from The Technology Partnership (TTP).
Cell sorting is a staple of many cell biology labs. The current gold standard, fluorescence-activated cell sorting (FACS), is limited to processing roughly 10,000 cells per second to avoid irreparable damage. For many new advances in cell therapy (e.g., autologous T-cell therapy for cancer), throughput of up to a billion cells in a few hours is essential. TTP set out to break through the current limit by developing a novel microfluidic cell sorter.
In this webinar, Robyn will discuss how TTP used the COMSOL Multiphysics® software to design and invent the world’s smallest ultrafast microfluidic cell sorter, where the key discovery was the inertial vortex. Robyn will also show how TTP's simulations correspond to reality with their fully working microfluidic chip.
The webinar will include a live demonstration and conclude with a Q&A session.
