Charge change: How electric forces vary in colloids

When calculating electrokinetic force, the convention has been to assume that there is no relative velocity of the fluid compared to the surface, which holds true for hydrophilic surfaces. However, this needs to be reconsidered ...

Carnivorous plants: No escape for mosquitoes

Physically bound to a specific location, plants have to devise special ways to secure their supply of vital nutrients. Most plants have developed a root system to the nutrients they need in order to survive out of the soil. ...

New cellulose-based material represents three sensors in one

Cellulose soaked in a carefully designed polymer mixture acts as a sensor to measure pressure, temperature and humidity at the same time. The measurements are completely independent of each other. The ability to measure pressure, ...

Quantum sensing method measures minuscule magnetic fields

A new way of measuring atomic-scale magnetic fields with great precision, not only up and down but sideways as well, has been developed by researchers at MIT. The new tool could be useful in applications as diverse as mapping ...
