Turning a porous material's color on and off with acid

A research team led by Hokkaido University in Japan has constructed a porous material that is very stable and changes color when exposed to acid vapor. This is believed to be the first reported instance of a hydrogen-bonded ...

Nanotubes change the shape of water

First, according to Rice University engineers, get a nanotube hole. Then insert water. If the nanotube is just the right width, the water molecules will align into a square rod.

Transforming gas into fuels with better alloys

Technological advances in oil and gas well stimulation over the past decade now allow for the production of natural gas from shale gas trapped in rock formations underground. With the sudden increase in the availability of ...

Computing power solves molecular mystery

Chemical reactions take place around us all the time—in the air we breathe, the water we drink, and in the factories that make products we use in everyday life. And those reactions are unexpectedly fast. Given optimal conditions, ...
