What is the difference in oils between "synthetic oil" and "two stroke/cycle oil", bearing in mind I known 2 cycle is for 2 strokes. "Synthetic oil" doesn't seem very specific and I don't know whether to use this instead of 2 cycle for any kind of engine and just for general use. And talking...
Hello, kind of focusing on the hydration of ethene/ ethylene, but how to liquid catalyst work if the reactants are gaseous? Does the acid catalyst also need to be gaseous if it is to work correctly?
Currently looking up all sorts of stuff about monopropellants(and catalysed reactions), but when anything talks about catalysts, they never say which one. Do all chemical classed as catalysts catalyse anything, could a catalyst bed H2O2 monopropellants decomposition just be a chunk of any random...
Hiya, I'm a bit of an intermediate in electronics and I am moving into oscillator territory and am thinking more about "ground" rather than "the negative side of the battery". Obviously, using -ve voltage as ground has some setbacks with dc-ac oscillators as current can only flow if there is a...
Hiya, I've been mucking around with a 2n7000 MOSFET and I can successfully turn it on and off, but to turn it off I either have to put the gate at 0v and wait a few seconds and it turns off itself or apply negative voltage to the gate and it'll stay off when I return it to 0v. Is this normal for...
Right, I know that plasma has a very high charge because of electrons doing stuff and that the plasma can be contained and controlled using an electromagnet, but can it be put the other way round? Say I have a chamber with plasma in it, generated by whatever, and I put an inductor outside the...
Hiya
Does anyone know if there's any safety or performance issues with going about the input voltage of a transformer? The spec on maplin says on just about every step down transformer that the input is (x)v-230v. As I live in the uk, mains voltages are 240v a.c. Not sure about what to do
