The precursors (iron sources and oxidants) were pulsed alternately into the reactor, separated by N2 gas purge (purity > 99.999%) to realize the ALD deposition.
Revlon Customeyes mascara has a convertible flexible brush, designed to alternately volumize and separate lashes.
The parts of a lock, disassembled so that the bolt is separated from the snib, appear alternately hostile when opposed at either end of a wooden block, or humorous when one is hidden round a corner from the other.

The products were separated by centrifugation and washed with deionized water and ethanol alternately for three times.
Alternately, you can just separate the bananas from the bunch and then wrap the step of each one individually.
Fura-Red was alternately excited with the 405 and 488 nm lasers, and fluorescence signals were separated from excitation wavelengths using a quad-band dichroic mirror and emission filter set (405/488/561/640, Semrock Inc., Rochester, NY, USA).
Amino group-modified Fe3O4 nanoparticles were separated by a NdFeB magnet and washed several times with methanol and Milli-Q water alternately and then dried at 50°C in a vacuum oven.
The reaction solution was then cooled down to room temperature and the solid product was separated from the reaction mixture by centrifugation (4000 rpm), and was washed with ethanol and water alternately, each for three times.
