Strong saturable absorption was found,the excited states effective absorption cross section was σ_(eff)=(1.47×10~(-18) cm~2,) and the corresponding nonlinear absorption coefficient was β=(-4.36×10~(-12) m/W.)
The electronic structure,ground and excited-states spectra (S0→Sn,S1→Sn,T1→Tn),excited-state molecular dynamics and micromechanism of reverse saturable absorption of C60 molecule were studied by using INDO/CI method.
At 1GHz,the initial permeability was μ′=5.3 and μ″=3.45.The optimized temperature of crystallization of the thin-film was near 600℃,at which the fabricated grain size was about 13nm,the saturate magnetization Ms was 2.29×105A/m,and the coercivity Hc was 1.24×103A/m.
It is determined that the static and dynamic saturate adsorption capacity of wet D296r resin are 27.58mg/ml and 28.02mg/ml respectively, and those of wet D261 are resin 25.28mg/ml and 26.64mg/ml respectively.
(3) with the sintering temperature increasing, the specific saturate magnetization Bs of these bulk alloys increases and coercive force Hc decreases, respectively. Fe70Cr8Mo2Si5B15 bulk alloy has the lowest Hc, 4.1kA·m-1.
The binding of 125I-labeled pentarphin to mouse peritoneal macrophages was highaffinity (Kd = 3.6 ± 0.3 nM) and saturable.
A high-voltage switch of submicrosecond range based on an assembly of reverse switch-on dynistors (RSDs) connected in series and a coaxial saturable-core choke is described.
Dynistors are triggered using a control circuit in the form of a high-voltage magnetic-compression section, in which the current-forming capacitor is charged from the power-circuit capacitor using an additional low-power saturable-core choke.
Physical processes occurring upon turning-on of the transistor in a converter stage with a saturable-core choke, placed in the clamping diode's circuit, are analyzed.
It is shown that the use of the saturable-core choke can be expected to reduce the energy loss by half or more.
