Overall-Design Techniques

1999
In the previous chapters we have seen how to design input stages and output stages. The next step in the design of operational amplifiers consists of determining the required number of stages; for that we consider the main overall parameters of amplifiers. The main overall parameters of operational amplifiers are dc-gain and speed.

Rational design of Z-scheme PtS-ZnIn2S4/WO3-MnO2 for overall photo-catalytic water splitting under visible light

, 2019
ZnIn2S4/WO3 nanocomposites, with ZnIn2S4 nanosheets loaded on WO3 nanorods, were synthesized by self-assembly of hexagonal ZnIn2S4 in the presence of preformed WO3·H2O nanoplates. PtS and MnO2, the co-catalysts for H2 and O2 evolution, respectively, were

Overall Radio-HPLC Design

1986
The separation and detection of radioactive tracers by high performance liquid chromatography (radio-HPLC) incorporates many of the same design considerations of conventional (nonradio) HPLC. There are several excellent books that describe the principles of HPLC and contain additional specialized applications and considerations not covered in this ...
