@nsaspook Thanks for introducing me to the RTL-SDR. That's a really cool product. Here's an idea for signal throughput in 'detect mode':
RF damped sine wive inductively detected with loop -> LNA -> fixed-frequency transmitter (crystal oscillator?) -> RTL-SDR -> computer
@analogdesign I agree...
Hi Physics Forums,
I'm a biochemist whose electronics experience is limited to resonant RLC circuits. I have been tasked with building a device that essentially acts as an RF antenna. In transmit mode, this device must create a sine wave of specific frequency (current plan is 40.05 MHz)...
Remember that the molecular masses you listed are in units of g/mol (grams per mole), where one mole is one Avogadro's number of molecules (1 mol = 6.022 x 10^23 molecules). So 100 molecules is a small fraction of a mole while 100 g could be a multiple or fraction (depending on the molecular...
First, some terminology: the amino acid is "cysteine." "Cystine" is two cysteines held together by a disulfide linkage via their side chains.
If I remember correctly, HCl is utilized to hydrolyze the peptide bonds during primary structure characterization. This operates through a standard...
All look incorrect to me.
a.) O3+ should be O2-; in addition, two positive ions do not form an ionic bond.
b.) Ionic compound should be CrI3 (one Cr3+ per three I-).
c.) Ionic compound should be CuO (one Cu2+ per one O2-).
d.) Ionic compound should be Sn3N4 (three Sn4+ per four N3-).
Given the...
