(Phys.org)—As electrical pulses travel through the body's nervous system, they are passed from neuron to neuron by synapses. A synapse, which consists of a gap junction and the cell membranes of the transmitting and receiving ...
European scientists developed a novel foundry process using moulds formed by 'binding' metallic particles with application of a magnetic field. The process produced high-quality, complex parts at a very competitive cost.
