How is it that some kinds of light can pass through things without stopping? And how can scientists use this ability to see inside things like rocks, soils, and man-made materials at a microscopic level and understand their inner workings? We're joined by Dr. Mayank Sabharwal to talk about the fascinating power of x-rays and some of the ways that scientists use this super-powered light to do much more than look at broken bones.
In this month's After School Science Hour we'll be diving into the science of polymers and learning about how plastics work on a molecular level. We'll also learn how the chemistry of polymers plays a role in recycling, and how Berkeley Lab scientists created an infinitely recyclable plastic.
What does it take to engineer a magnet smaller than any other? Berkeley Lab scientist Jie Yao will talk to us about his team's recent creation of the first-ever 2D magnet: a material that is magnetic at only one atom thick! We'll discuss what went into this remarkable achievement, hear what fields and industries it will affect, and see some magnetism demos in action.
From holiday string lights to the bright sun in the sky, light is everywhere around us - but what really is light? Get all your questions about light answered by Berkeley Lab scientists Baishakhi Bose, Mayank Sabharwal, and Yu Gao during December's After School Science Hour about the inner life of light. You'll also get to make your own sky simulator and learn the reasons behind the sky's changing colors.
How do scientists stay safe when they work with poisonous fumes and powerful acids? For November's After School Science Hour, Karla Arredondo and Ladan Khandel from Berkeley Lab's Environmental, Health, and Safety (EHS) Division will share how they help scientists carry out their research safely. Get a behind the scenes look into a lab's safety equipment from fume hoods to hazmat suits. Afterwards learn how to create a pollution catcher to test air quality.
It's almost Halloween and the zombies can't wait to get out of their tombs! Berkeley Lab scientist Dr. Nobumichi Tamura will share his research on a 2050-year-old Roman tomb, and how the crystalline structure within the tomb's concrete made it so strong that it's still standing today. Attendees will learn how to create their own 3D crystal models to design and build their own tombs. Will your tomb be strong enough to prevent a zombie apocalypse?
