#Desalination with nanoporous graphene membrane Less than 1 percent of Earth's water is drinkable. Removing salt and other minerals from our biggest available source of water--seawater--may help satisfy a growing global population thirsty for fresh water for drinking, farming, transportation, heating, cooling and industry.
Today reverse-osmosis filters are typically polymers. A filter is thin and resides on a support.
A porous graphene membrane could be more permeable than a polymer membrane, so separated water would drive faster through the membrane under the same conditions, the scientists reasoned."
The researchers transferred the graphene membrane to a silicon nitride support with a micrometer-sized hole.
The silicon nitride chip held the graphene membrane in place while water flowed through it from one chamber to the other.

#Chemical engineers outline new approach to materials design The findings reveal a unique model that enables fast and accurate prediction of novel alloy materials for efficient chemical conversions.
The mixture of two or more metals with very precise atomic structures and compositions has shown great promise for catalyzing many chemical and electrochemical reactions,
In the past, testing of mixed blends of metals has produced novel physical and chemical properties. However the process is very time-consuming and costly to search for highly optimized alloys using the conventional approaches, Achenie added.
So that is why Achenie and Xin decided to use existing data to train computer algorithms to make predictions of new materials,
thus allowing large scale exploration alloy materials space, according to their article. They specifically concentrated on the electrochemical reduction of carbon dioxide on metal electrodes because of the current interest in this process for sustainable production of fuels and value added chemicals,
they have identified a few promising copper multi-metallics with a higher energy conversion efficiency and possibly higher selectivity in carbon dioxide electro-reduction to ethylene, an extremely useful chemical in industry for making plastics.
