Ion channels are pores in the membrane of cells or cell organelles. They allow positively or negatively charged particles, so-called ions, to be transported across the membrane. Biochemists at ...

Carbon nanotubes can open and close in response to acidity, guiding water and ions one by one and mimicking how natural cell channels work. (Nanowerk News) When water and ions move together through ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American I remember learning about acids and bases (or ...

The pH meters are electronic devices designed to measure the acidity or alkalinity by detecting the voltage produced by a ...

In addition to pH, ion, voltage and temperature measurement, the combined 781 pH/Ion Meter also offers an automatic stirrer control, a multi-point calibration with up to nine buffers (pH mode), a ...

In literature, the terms “ion exchange chromatography” and “ion chromatography” (IC) are often used interchangeably, thanks to the wide use of IEX, and refer to the separation of polar or ionic ...

The pH scale measures the acidity or alkalinity of a substance, ranging from 0 to 14, with values below 7 representing acidity, above 7 representing alkalinity, and 7 representing neutrality.
