Teaching, Learning and Research in new and emerging technologies require state of the art laboratories equipped with expensive equipment and associated support facilities. However, such facilities also require large financial resources and time restraints to implement the requirements. Use of Web-based Simulation and Remote Access Visualization Tools enhance students’ learning and teaching of new and complex concepts without physically using required expensive equipment. In addition to cost savings, web-based simulation and remote access/online visualization approach offer several advantages:
• Allowing the user to modify system parameters and observe the outcomes without any harmful side effects
• Eliminating component or equipment faults that affect outcomes
• Supporting users progress at their own pace in discovering and understanding of concepts, outcomes and issues
• Enhancing the presentation and understanding of ‘the dry and abstract’ concepts by integrating theory and practice

Focus Areas:

• Online Visualization at the nanoscale using web-based remote access instruments
• NanoHUB Online Platform’s Simulations Tools for applications in areas of nanoelectronics and biological sciences for nanoscale modelling.
• Simulation experience with X-ray characterization using XPS and XRD

The proposed workshop will discuss application of online simulation tools and remote access visualization for teaching, research, and collaboration in the areas of nanotechnology, material science, environmental science, electrical engineering, biological sciences, physics, chemistry, photonics and much more. These tools include 26 RAIN (Remote Access Instruments in Nanotechnology) nodes for accessing visualization instruments; 500+ simulation tools at nanoHuBTM to simulate nanotechnology processes; interactive simulations at Phet Interactive Simulations for Physical Sciences and Math; and CompuCell3D & Physicell flexible modeling platforms that allow simulations for biology, tissue engineering, and viruses including COVID19. Best Practices and Simulation Experiences at PSU with X-Ray characterization using XPS and XRD are also included for presentation.


1. Remote Access Instruments in Nanotechnology (RAIN) is a network of 26 centers across continental US which allows students to access and control microscopes and analytical tools, to look at nanosized materials from the ease of classrooms, or home computers. Each center has tools of unique functionality, all with micro- and nano-capabilities. And offers the services free of charge to the Students and Instructors those would otherwise not encounter / access such resources. Students control the tools over the Internet from these centers in real-time which is achieved with the assistance of a trained staff member at the microscope facilities/centers advising over video conferencing software. RAIN has prepared a series of nano-based labs and basic science labs which can be accessed through nanoHUB.
2. nanoHUB is an open- and free-platform, located at Purdue University (Indiana, USA), which runs in the cloud and contains more than 500 simulation tools and 6500 resources. It is a shared online platform for teachers, students and researchers. This can be used to learn modelling, develop, run and share research models covering range of applications from nanoelectronics, to biological science and artificial intelligence to biological modelling. nanoHUB simulations are available to users as both stand -alone tools and part of structured teaching and learning. It is presently accessed by more than 1.5 million users worldwide.
3. CompuCell3D and PhysiCell, also available at nanoHUB platform, offer applications in multicellular simulation of viruses like infamous Covid-19. CompuCell3D is a flexible scriptable modeling environment, which allows the rapid construction of sharable virtual tissue models, accessible to users without extensive software development or programming experience. CompuCell3D models uses multi-scale approach for modelling the behavior of multi-cell biological systems and have been used to solve basic biological problems, medical therapies, and assess modes of action of toxicants and design engineered tissues. COVID-19 virtual tissue model for simulating tissue-immune system interactions—a virtual infection was added to nanoHUB in 2021.
4. PhysiCell is an open source, agent-based simulation framework for simulating complex multicellular systems. It aims to provide a scalable code for simulating at least 500,000 cells in 3-D tissue on desk top computer which move according to biomechanical forces and are not constrained by the lattice positions. This simulation based on individual cell behavior and cell to cell interaction can be applied to infection diseases such as COVID19, cancer, immunology, developmental biology, micro-ecosystems and more. A comprehensive multiscale simulation framework for SARS-CoV-2 (coronavirus) infections in lung and gut tissues was assembled by an international coalition in 2020, to understand and test interventions in the coupled dynamics of COVID19.
5. PhET Interactive Simulations platform, located at University of Colorado, provides several interactive simulations for Physics, Chemistry, Math, Environmental Sciences and Biological Sciences. PhET simulations help students to: (a) engage in scientific exploration with multiple, positive learning (b) achieve conceptual learning (c) make connections to everyday life (e.g., science to the real world), and (d) take and sense ownership of their learning. PhET simulations also help educators to: (a) create a student-centered classroom (b) foster a supportive, goal-oriented learning environment (c) bring their experience, professionalism, and knowledge of their students for designing, implementing, and improving activities, implementation, and sim designs.
