A new microscale gas chromatography system integrates all fluidic components into a single chip for the first time. The design leverages three Knudsen pumps that move gas molecules using heat ...

The workings of electricity are often introduced to students by way of a comparison to water, with voltage analogous to ...

We describe electricity as a flow, but that’s not what happens in a typical wire. Physicists have begun to induce electrons to act like fluids, an effort that could illuminate new ways of thinking ...

Scientists have developed a powerful new way to trace the journey of water across the planet by reading tiny atomic clues hidden inside it. Slightly heavier versions of hydrogen and oxygen, called ...

Abstract: Multiple water quality sensors are required to construct a network for continuous and precise monitoring of water quality in natural environments. Therefore, low-cost sensors are necessary ...

Abstract: This article proposes a scale-independent adaptive control strategy that allows a quadrotor to rely solely on optic flow output to achieve a soft vertical landing on stationary surfaces.
