Filters are one of the best ways to trap and remove pollution and small particles from the air. Let’s learn how spiderweb-like networks can be made from polymer into incredible filters.
There’s a new record holder for the world’s blackest material. Learn about how randomly oriented carbon nanotubes can be used to create a coating darker than anything else ever made!
Electrical circuits can be drawn, erased, and redrawn with ease on this new material that uses liquid metal particles suspended in a polymer network. Check out how it’s made and its potential uses in flexible electronics!
Switching to solar energy is one of the ways we can fight against climate change. Let’s learn how something as harmful as the greenhouse effect can be used to create better solar devices!
Nothing compares to a well-trained dog’s nose for smelling out faint odors. But a new artificial nose made with living cells may come close!
Gold is one of the most important metals since it’s used in electronics. Let’s learn from Charlie about a new material than can help recycle gold from discarded devices!
We use lithium-ion batteries in our electronics every day, but getting the materials to build them isn’t very environmentally friendly. Let’s learn about a new way to recover one of these materials from burnt plants!
Fluorescent proteins are incredibly useful for exploring the inside of living cells. Let’s learn about a new way to find better-performing proteins using machine learning!
Measuring blood sugar levels by pricking your finger is painful and inconvenient. Learn about a new wearable device that measures your glucose levels with just your sweat!
Fake medical tests are a huge problem in many poorer countries. Let’s learn about a way to print erasable codes on these devices so they can’t be counterfeited!
Making surfaces that oil can’t stick to is important for cleaning up oil spills and other pollution. Let’s find out about a new way to coat surfaces that makes them repel oil!
Graphene is a wonder-material that is nearly indestructible, conducts electricity, and flexible enough to be worn. Let’s learn how to make it with lasers on the surface of carbon-based materials!
Tailoring treatment for a specific patient is the future of medicine. Let’s learn about making tiny pills that are “smart” enough to know where to dissolve in the body!
Flexible touch screens and see-through electronics could be closer than you think! Let’s learn about a new way to make transparent conductors with silver nanowires!
Ever taken a bite of ice cream and wondered why it’s so smooth? In this paper, the chemical responsible for that is extracted from seaweed and nothing is wasted!
Tiny machines fixing disease inside the body may not be science fiction for much longer! Let’s learn about making and controlling nanomotors that could one day deliver drugs from within!
One of the most important types of chemicals in agriculture is fertilizer. This paper shows a new way to cleanly make fertilizer from a very common mineral!
