Peter Bøggild
Bio: Peter Bøggild is professor and group leader at DTU Physics at the Technical University of Denmark. He obtained his PhD in low temperature solid state physics at the Copenhagen University in 1998, and became a full professor in 2013 at DTU. He has worked across numerous areas, including nanomechatronics/robotics, topology optimization, nanometrology, nanotubes/nanowires, surface science, material synthesis and microfabrication, mesoscopic physics and simulations, but is today is leading a group entirely focusing on graphene and other 2D materials, with emphasis on large scale fabrication/applications, electronics, terahertz metrology and material science. He has published nearly 200 papers, most of which are on 2D materials, and is committed to push fundamental research in two-dimensional materials towards real and viable technologies and applications. He is main organizer of the international conference Carbonhagen, which has run annually since 2010, latest in 2020 as an online meeting.
Abstract: As monolayer graphene films made by CVD growth are becoming available at competitive price point and quality, the list of attractive applications grow within electronics and photonics. There is a strong need for large-scale, non-destructive characterisation techniques as traditional field-effect device are cumbersome and ineffective in providing spatial information on the electric properties on a large scale. While lithographic processing to some extent destroys the fragile graphene film, scanning probes that rely on physical contact with the graphene film also lead to unwanted scratches and contamination. Since the terahertz absorption of graphene is directly linked to its electrical conductivity, terahertz time-domain spectroscopy allows to extract not only the conductivity, but also carrier density, carrier mobility and even Fermi velocity from a graphene film, without physical contact. In the talk, I will overview our efforts towards making THz-TDS a viable metrology technique. In early 2021 we publish an International Electrotechnical Commission (IEC) metrology standard and a comprehensive review article that overviews selected exemplary cases from our numerous collaborations on graphene on polymer substrates, silicon carbide, silicon, and sapphire, as well as encapsulated graphene. I will show how useful insights into the impact of imperfections and non-uniformity on the electrical properties and the spatial uniformity can be extracted from THz-TDS maps. The talk will highlight the strengths and weaknesses of the technique and discuss what is needed to realise high speed inline electrical characterisation in a production environment.

Abstract: The fabrication and characterization of disordered materials has recently witnessed an outstanding progress leading to materials with unprecedented properties. In particular, the possibility to synthesize wafer-scale two-dimensional amorphous carbon monolayers, structurally dominated by sp2 hybridization, has been demonstrated. This achievement has initiated a new platform of lowdimensional materials allowing to explore alternative forms of membranes with enhanced chemical reactivity which could be employed for coating. The excellent physical properties of the mentioned materials derive from the nature and degree of their disorder which, controlled at the fabrication level, represents the key ingredient to tune their physical/chemical properties for specific target applications. In this respect, new fabrication strategies to modify the degree of disorder and a systematic theoretical characterization of the impact of the material structural quality on the ultimate performance is urgent. Even more importantly, the search for new disordered materials for novel applications appears as an extremely promising way. In this talk we present a systematic analysis of the structural, vibrational and electronic properties of amorphous carbon monolayers as a function of the structural quality of the material. We hence show how disorder results in a tunable electrical conductivity and mean free path. In addition, a strong variation of thermal conductivity varying by more than one order of magnitude is found. Finally, we present the results of the newly demonstrated synthesis of a thin film of amorphous Boron Nitride showing extremely low dielectric characteristics: high breakdown voltage and likely superior metal barrier properties . The fabricated material aims at replacing current interconnect insulators in the next-generation of electronic circuits. We discuss the experimental setup and present the results of our calculations which have contributed to the understanding of the structural morphology of the amorphous material. We conclude discussing the resulting thermal and electronic properties.

Abstract: Graphene and graphene-related materials display a combination of properties that make them very attractive for a broad variety of applications, among them biomedical and medtech applications. During the last years we have witnessed an increasing amount of evidence demonstrating that prototype devices based on these materials can surpass the performance and technical specifications of the state-of-the-art technology. However, the demonstration of an improved technical performance does not guarantee a successful translation to a clinical product; in the field of medtech, regulatory hurdles, for instance, are particularly penalizing for novel materials. In this presentation I will discuss on the opportunities and challenges of graphene technology for biomedical and medical applications, with a particular focus on devices that are intended to interface with the nervous system, such as implantable devices to monitor and modulate brain activity for diagnosis or therapy purposes. Clinical applications of these devices are, for instance, the treatment of brain disorders such as Parkinson´s disease or epilepsy, or the development of brain-machine interfaces to help patients with sensory or motor disabilities. I will review recent developments in the field, with a particular attention to the technical and scientific grounds of these developments. Further, I will also discuss other non-technical challenges that these technologies will have to overcome to be eventually translated into medtech products.
Lucia Gemma Delogu
Bio: Lucia Gemma Delogu, Ph.D., is the head of the ImmuneNano-Lab at the Department of Biomedical Sciences of the University of Padua (UNIPD, Padua, Italy) www.delogulab.eu. After acquiring her experience in Immunology and Material Science at the University of Southern California (Los Angeles, USA) and at Sanford-Burnham Institute (San Diego, USA), she served as Assistant Professor at the University of Sassari (Italy) and as Visiting Professor at the Technische Universität Dresden (TUD; Dresden, Germany). Dr. Delogu has been the Scientific Coordinator of two interdisciplinary EU projects, under HORIZON2020, on nanomedicine and immune interactions of nanomaterials. In this field, she has received several awards, including the “Marie S. Curie Individual Fellow”, the “200 Young Best Talents of Italy 2011” from the Italian Ministry of Youth, and “Bedside to Bench & Back Award” from the National Institutes of Health, USA. Since 2020, Dr. Delogu is in charge of the Italian chapter and a member of the road map working group of the Advanced Material Global Pandemic & Future Preparedness Taskforce (AMPT) www.amptnetwork.com.
She introduced the “NanoImmunity-by-design” concept for the design of nanomaterials based not solely on their physicochemical characteristics but also on their immunomodulatory properties. She pioneered the use of systems immunology approach by high-dimensional single-cell strategies in the context of nanomaterial applications.
Abstract: Two dimensional materials such as graphene and Mxenes are destined to leave an indelible mark in many application areas including biomedicine. In particular, due to a multitude of exceptional intrinsic properties, these materials offer new perspectives for the development of advanced tools for therapeutic delivery approaches, imaging, cancer theranostics, and tissue regeneration or engineering. For any biomedical applications, the immune system plays a fundamental role. Understanding whether and how immune cells respond to nanomaterials by immune activation or immunosuppression might allow taking advantage of both of those selected intrinsic immune properties. For example, immuneactivation could be useful to stimulate the immune system against malignant cells in cancer immunotherapy or as vaccine adjuvants. On the other hand, immunosuppression may find applications for overactive inflammation in allergic reactions, chronic inflammation, autoimmune disorders, and organ transplantation. Here we present our “Nanoimmunity-by-design concepts”as well as published and unpublished data on the immune-based applications of graphene, Mxenes and other advanced 2D materials.

Abstract: 2D materials, including graphene, display unique physicochemical properties and have generated a high interest for biological applications. They have been exploited for photothermal therapy, in drug delivery, tissue engineering, and biosensing. Functionalization enables to impart novel properties and also to modulate their interactions with biological molecules. In this talk, I will show the impact of the functionalization of graphene family nanomaterials on their interactions with nucleic acids for gene therapy, with immune cells allowing to increase their biocompatibility, and with enzymes to enhance their biodegradability. I will also give an overview of the literature on the interactions of 2D materials, mainly graphene family nanomaterials, with viruses, focusing on the main factors governing these interactions. An emphasize will be given on how functionalization can endow the materials with selectivity. Different strategies for the development of 2D-material biosensors for the detection of viral infections will be presented, including the sensing of viruses, viral nucleic acids, and antibodies. I will critically detail the advantages and drawbacks of 2D materials, and provide insights for the development of future biosensors for virus detection. Some suggestions will be given to stimulate research that could help in designing advanced systems for preventing virus-related pandemics.
In the next issue of this newsletter I will have the possibility to offer you the first of a series of interviews with young researchers. Don't hesitate to subscribe if you haven't already done so.
