Abstract: This work proposes a low-cost battery-less near-field communication (NFC) tag for gas sensing based on a resistive gas sensor. A proof-of-concept tag is designed using commercially available ...

Researchers from the Cancer Science Institute of Singapore (CSI Singapore) at NUS have developed a new method that allows ...

Quantum states can be precisely controlled with the help of tiny carbon rings measuring only a few nanometers in size. This ...

In a world regulated by devices, humanity has become disconnected from the physical world—from stick-shift cars to postcards.

Much like radio operators being encouraged to use the least possible amount of power to make a contact, chemists have a ...

There are plenty of radios you can buy that pick up MW and SW bands if that’s what you’re into. Or, you can follow [mircemk]’s example, and whip one up yourself instead. The build employs an ESP32 as ...

A major breakthrough in quantum technology has turned magnons, tiny magnetic waves once considered too short-lived for ...

Over the past several decades, the semiconductor industry has experienced sustained growth. Early expansion was driven by the ...
