Effect of atomization on surface oxide composition in 316L stainless steel powders for additive manufacturing

Surface and Interface Analysis, 2020
The initial oxide state of powder is essential to the robust additive manufacturing of metal components using powder bed fusion processes. However, the variation of the powder surface oxide composition as a function of the atomizing medium is not clear ...

Atom Interferometry with Floquet Atom Optics

Physical Review Letters, 2022
Floquet engineering offers a compelling approach for designing the time evolution of periodically driven systems. We implement a periodic atom-light coupling to realize Floquet atom optics on the strontium ${}^1\!S_0\,\text{-}\, {}^3\!P_1$ transition.

Effects of drop and film viscosity on drop impacts onto thin films [PDF]

, 2013
While drop-film impacts have been studied extensively in the past, little thought has been given towards separating the effects of the drop fluid properties from those of the film.

Breaking the Rayleigh-Plateau instability limit using thermocavitation within a droplet [PDF]

, 2013
We report on the generation of liquid columns that extend far beyond the traditional Rayleigh-Plateau instability onset. The columns are driven by the acoustic pressure wave emitted after bubble collapse.

Quantitative Expression of a Slight Deviation of the Impact Angle in a Collision Atomizer

Machines, 2022
In the processing of colliding atomizers, a small change in the inclination of each orifice will double the impact angle, seriously affecting its atomization performance.
