Chemical etching method opens pores for fuel cells and more

A chemical etching method for widening the pores of metal-organic frameworks (MOFs) could improve various applications of MOFs, including in fuel cells and as catalysts. Researchers at Nagoya University in Japan and East ...

2D material in three dimensions

The carbon material graphene has no well-defined thickness; it merely consists of one single layer of atoms. It is therefore often referred to as a "two-dimensional material." Trying to make a three-dimensional structure ...

Oysters produce 3-D structures organised by physical processes

Scientists from the University of Granada (UGR) have discovered that oysters are capable of producing three-dimensional structures organized by physical (colloidal) processes—the result of which resembles a solid foam—by ...

Researchers 3-D print biomedical parts with supersonic speed

Forget glue, screws, heat or other traditional bonding methods. A Cornell University-led collaboration has developed a 3-D printing technique that creates cellular metallic materials by smashing together powder particles ...
