Tips with an exceptionally small orifice are ideal for use with low-density liquids, like PCR reagents. The extra narrow tip orifice, in combination with the extended length of the tip, means that ...

But what does that mean? The simple answer is how heavy something is for its size. If something seems very heavy for its size (like a heavy metal object), we say it is more dense. If something seems ...

A nanoporous material that holds hydrogen at twice the density of cryogenic liquid H2 could address the challenges of large-scale liquid and gas storage that have held this clean fuel back. Hydrogen ...

WeLion, a Chinese developer of solid-state batteries, is making good progress toward achieving a long-term energy density of ...
