You can make all sorts of different types of inductors, but the most common type is cylindrical coil of wire---a solenoid. When current runs through the first loop, it creates a magnetic field that ...

Square-root-calculating circuits find wide use in instrumentation and measurement systems for such tasks as calculating the rms (root-mean-square) value of an arbitrary waveform, for example. Hence, ...

Discover how to create a simple thermal motor using an aluminum can and two small DC motors. This step-by-step tutorial demonstrates each stage of building a DIY thermal engine that transforms heat ...

We introduce a new method for the purification of recombinant proteins expressed in Escherichia coli using self-cleaving elastin-like polypeptide (ELP) fusion tags without the need for affinity ...
