Vor 4 Tagen · Low voltage increases image contrast which is especially important for biological specimens. This increase in contrast significantly reduces, or even eliminates the need to stain. Resolutions of a few nm are possible in TEM, SEM and STEM modes. The low energy of the electron beam means that permanent magnets can be used as lenses and ...

Vor 4 Tagen · Overview. Developmental bioelectricity is a sub-discipline of biology, related to, but distinct from, neurophysiology and bioelectromagnetics. Developmental bioelectricity refers to the endogenous ion fluxes, transmembrane and transepithelial voltage gradients, and electric currents and fields produced and sustained in living cells and tissues.
Vor 5 Tagen · [This is a follow-up to Monday’s post, going more into depth.]. Among the known elementary particles are three cousins: the electron, the muon and the tau.The three are identical in all known experiments — they have all the same electromagnetic and weak nuclear interactions, and no strong nuclear interactions — except for effects that arise from the fact that they have different rest masses:
Vor 2 Tagen · July Thomas , Derik K , a b , and. 1 other. contributed. Resonance occurs in a circuit when the reactances within a circuit cancel one another out. As a result, the impedance is at a minimum and the current is at a maximum. Mathematically, the condition for resonance is. X_L = X_C. X L = X C. Resonance allows for the maximum power output of an ...
Vor 5 Tagen · Ohm’s law is the name of a relationship between current, 𝐼 (in units of amperes); resistance, 𝑅 (in units of ohms); and potential difference, 𝑉 (in units of volts) in many conductors: 𝑉 = 𝐼 × 𝑅. Ohm’s law may be rearranged so that the current or the resistance is the subject: 𝐼 = 𝑉 𝑅 and 𝑅 = 𝑉 𝐼.
Vor 4 Tagen · Our family of gallium nitride (GaN) FETs with integrated gate drivers and GaN power devices offers the most efficient GaN solution with lifetime reliability and cost advantages. GaN transistors switch much faster than silicon MOSFETs, offering the potential to achieve lower-switching losses. Our GaN power stages can be used in a wide range of ...
