A titanate nanowire mask that can eliminate pathogens

Filter 'paper' made from titanium oxide nanowires is capable of trapping pathogens and destroying them with light. This discovery by an EPFL laboratory could be put to use in personal protective equipment, as well as in ventilation ...

Groovy key to nanotubes in 2-D

Ultrathin carbon nanotubes crystals could have wonderous uses, like converting waste heat into electricity with near-perfect efficiency, and Rice University engineers have taken a big step toward that goal.

Paper filter from local algae could save lives in Bangladesh

The problem of access to safe drinking water in most parts of Bangladesh is a persistent challenge. Now, a team of scientists from Uppsala University, Sweden, and Dhaka University, Bangladesh, shows that a locally growing ...

Better and cheaper healthcare with dry blood samples

Dried blood on filter paper stored for future diagnostic purposes – considerably easier than the present-day, resource-consuming method using frozen blood samples in plastic tubes. In a new study, Uppsala researchers have ...

Mille-feuille-filter removes viruses from water

A simple paper sheet made by scientists at Uppsala University can improve the quality of life for millions of people by removing resistant viruses from water. The sheet, made of cellulose nanofibers, is called the mille-feuille ...

Portable device can quickly determine the extent of an eye injury

An engineer and an ophthalmologist are developing a portable sensor that can quickly and inexpensively determine whether an eye injury is mild or severe. The device, called OcuCheck, measures levels of vitamin C in the fluids ...
