Smoothing Out The Rough Edges Of 3D Printed Objects
Researchers have developed a surface finishing process for 3D printed objects that combines better quality with low cost and less waste.
One Material, Three Colors
Researchers have developed a material that can switch its color between yellow, red and orange in response to heating, fuming and grinding.
Soft, But Stronger Than Steel
By combining soft hydrogels with a woven glass fiber fabric, researchers have made a highly flexible composite material that is tougher than steel.
Smashing Silicon To Make Lithium Batteries
Pulverized waste silicon be recycled into a high-performance anode material for lithium-ion batteries.
Sugar-Coated Catalysts That Work In Live Mice
Carbohydrate structures called glycans could help researchers send metal catalysts to specific tissues without the need for time-consuming antibody development.
A Wearable Battery Made From Green Tea
Wearable electronics like sports bands and smart watches could be more comfortable with the help of a green tea extract.
New Material Doubles Negative Thermal Expansion Record
Most materials expand when heated; researchers have now found one that contracts by nearly 7 percent instead.
The World’s Thinnest Oxide Semiconductor
This oxide semiconductor is just one-atom thick, opening up new possibilities for flexible, wearable technologies.
How Do 2D Materials Crack?
To understand how thin two dimensional materials crack, we must go beyond existing theory, scientists say.
