The Gulf of Maine—home to commercial fisheries for oysters, clams and mussels—has unexpectedly avoided an increase in seawater acidity, helping to preserve the health of its fisheries. The Gulf's ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

The key to the design are the folding “wings” which allow the robot to raise and lower itself on command. This not only helps it navigate tight spaces, but also gives it considerable all-terrain ...

In a recent study published in Scientific Advances, researchers created a bioresorbable, cordless, passive sensor that monitors pH locally and detects stomach leakage early on. Study: Bioresorbable, ...

Smart home automation is the ultimate life hack, in my humble opinion. Whether for efficiency, accessibility, nerding out, or just plain laziness, all you need are smart home devices and a little ...

(Nanowerk News) Measuring the pH of substances gives us vital clues about the world around us, such as identifying contaminated water or checking the toxicity of medical or cosmetic products. Often, ...

It’s rare in 2023 for an instrument to be entirely analog, instead it’s more normal for a front-end to feed the analog-to-digital converter (ADC) in a microcontroller. Typically the front-end will do ...

Chemists at the Ural Federal University have created a sensor for determining the human saliva pH. This is a fluorophore with strong and stable emission, which picks up the smallest fluctuations in ...

The pH of the culture medium is a critical process parameter in cell culture bioprocesses. To successfully transfer processes between bioprocess systems and sites (i.e., in the course of process ...
