About This Simulation
Perform quasi-elastic neutron scattering experiments at a research facility while helping a group of scientists in the Arctic. Observe the structure of atomic layers inside a battery and see how some atoms move when it discharges.
Learning Objectives
- Distinguish the basic components of a rechargeable Li-ion battery
- Recognize in which cases neutrons as a probe might be preferred over x-rays in materials science
- Understand how and why neutrons are produced, moderated in wavelength, transported and detected in a large-scale materials research facility
- Understand neutron transmission imaging and its advantages in materials science
- Distinguish various forms of neutron interaction with a sample and the related neutron cross-sections
- Explain how slow molecular movement in a sample can be measured by quasi-elastic neutron scattering

Learn More About This Simulation
This short, targeted simulations was adapted from the full-length Materials Science with Neutrons simulation.
Are you curious to find out what happens inside a battery without any fear of breaking it? In this simulation, you will learn the basics of neutrons and how they can be used as probes in materials science. You will get to perform experiments in a modern large-scale research facility that requires special permission to enter.
Observe the principles of neutron diffraction
Neutrons are subatomic particles found in the nucleus of most atoms. Through a high-energy process neutrons can be expelled from atoms to produce a free neutron beam. You cannot see the neutron beam with the naked eye but it can penetrate through almost any material. In our experiment it interacts weakly with the sample as it passes through it before finally being recorded in a detector.
Perform a QENS experiment
When neutrons hit the sample, they sometimes change energy due to inelastic or quasi-elastic processes in the sample. Understand the principles of quasielastic neutron scattering (QENS) through an interactive animation and perform an experiment on your battery sample. Will you be able to use these results to explain why the battery doesn't work properly in the cold, and will you be able to assist the scientists on their mission in the Arctic?

For Science Programs Providing a Learning Advantage
North Dakota State College of Science
“They did the simulation at home, then completed the in-person lab within 30 minutes, no questions asked, and passed the quiz with flying colors.”
Lecturer in Human Physiology
University of Westminster
"I saw some of the students who clearly didn’t necessarily like sitting there reading a book discover they could turn on Labster and keep up with the rest of the class because it spoke to them.
Modesto City Schools
"Having something that's engaging for the students gives teachers that opportunity to breathe and get excited again. Because they're seeing the kids light up, they're seeing the kids engage with content."
Wenatchee Valley College
"The question always is, ‘Can we demonstrate that the students are meeting course outcomes?’ Check! We can do that.”
San José State University
"We surveyed over 400 students. More than 90% thought Labster was easy to navigate, and that it was fun, but more importantly, most of them felt confident that they could execute the labs in person. And that confidence is a big deal."

A Labster virtual lab is an interactive, multimedia assignment that students access right from their computers. Many Labster virtual labs prepare students for success in college by introducing foundational knowledge using multimedia visualizations that make it easier to understand complex concepts. Other Labster virtual labs prepare learners for careers in STEM labs by giving them realistic practice on lab techniques and procedures.
Labster’s virtual lab simulations are created by scientists and designed to maximize engagement and interactivity. Unlike watching a video or reading a textbook, Labster virtual labs are interactive. To make progress, students must think critically and solve a real-world problem. We believe that learning by doing makes STEM stick.
Yes, Labster is compatible with all major LMS (Learning Management Systems) including Blackboard, Canvas, D2L, Moodle, and many others. Students can access Labster like any other assignment. If your institution does not choose an LMS integration, students will log into Labster’s Course Manager once they have an account created. Your institution will decide which is the best access method.
Labster is available for purchase by instructors, faculty, and administrators at education institutions. Purchasing our starter package, Labster Explorer, can be done using a credit card if you are located in the USA, Canada, or Mexico. If you are outside of North America or are choosing a higher plan, please speak with a Labster sales representative. Compare plans.
Labster supports a wide range of STEM courses at the high school, college, and university level across fields in biology, chemistry, physics, and health sciences. You can identify topics for your courses by searching our Content Catalog.
