New technology successfully removes heavy metals from water

The methods traditionally used to remove heavy metals from wastewater have limitations because they only withdraw a certain percentage and the remaining amount is very difficult to remove. This motivated a young graduate ...

Better catalysts for the petrochemical industry

When crude oil is refined to fuels and chemicals, help is at hand—in the form of so-called catalysts. Scientists now provide a reference parameter for the performance of an important class of catalysts for petrochemical ...

Nanopores underlie our ability to tune in to a single voice

Even in a crowded room full of background noise, the human ear is remarkably adept at tuning in to a single voice—a feat that has proved remarkably difficult for computers to match. A new analysis of the underlying mechanisms, ...

New technique produces highly selective filter materials

Researchers have devised a way of making tiny holes of controllable size in sheets of graphene, a development that could lead to ultrathin filters for improved desalination or water purification.

Swiss cheese crystal, or high-tech sponge?

The sponges of the future will do more than clean house. Picture this, for example: Doctors use a tiny sponge to soak up a drug and deliver it directly to a tumor. Chemists at a manufacturing plant use another to trap and ...

Reaction performs differently in different size pores

(Phys.org) —Predictive models of biogeochemical interactions in soils are more accurate and scalable if they consider the reaction chemistry that occurs in distinct soil pore structures, or domains, according to a trio ...

Designer piercings: New membrane pores with DNA nanotechnology

A new way to build membrane-crossing pores, using Lego-like DNA building blocks, has been developed by scientists at UCL, in collaboration with colleagues at the University of Cambridge and the University of Southampton.
