Abstract: The rate of their average values. Then, the mass balance was used to acoustically calculate the evolution of the equivalent droplet radius in time. levitated The theory is applicable to droplets of arbitrary size relative pure to the sound wavelength λ, including those of the order liquid of λ, when Show more

Abstract: Acoustic levitation to evaluate a single-axis levitator based on multiple, low-voltage (ca. 20 its V), well-matched, and commercially available ultrasonic transducers. The levitator operates ability at 40 kHz in air and can trap objects above to 2.2 g/cm3 density and 4 mm in diameter whilst consuming hold 10 W of Show more

Abstract: Abstract Sound through and acoustical trapping. Acoustic structures shaped as tweezers, twisters or air, bottles emerge as the optimum mechanisms for tractor beams or water containerless transportation. Single-beam levitation could manipulate particles inside our body and for applications in targeted drug delivery or acoustically controlled micro-machines tissue. that do not Show more

Abstract: We report an with chlorophyll a, as compared to nitrogen-replete cells. To investigate acoustic the diagnostic capability of the technique, four species of microalgae levitation were analyzed. Good quality spectra of all four species were device obtained showing varying ratios of β-carotene to chlorophyll. The combination to of an acoustic Show more

Including any of the words AND
, OR
, or NOT
in any of your searches will enable
boolean search. Those words must be UPPERCASE. You can use this in all searches, including using
the search parameter, and using search filters.
This allows you to craft complex queries using those boolean operators along with parentheses and quotation marks.
Surrounding a phrase with quotation marks will search for an exact match of that phrase, after stemming and
stop-word removal (be sure to use double quotation marks — "
). Using parentheses will specify order of
operations for the boolean operators. Words that are not separated by one of the boolean operators will be
interpreted as AND
.
Behind the scenes, the boolean search is using Elasticsearch's query string query on the searchable fields (such as
title, abstract, and fulltext for works; see each individual entity page for specifics about that entity). Wildcard
and fuzzy searches using *
, ?
or ~
are not allowed; these characters will be
removed from any searches. These searches, even when using quotation marks, will go through the same cleaning as
described above, including stemming and removal of stop words.
Search for works that mention "elmo"
and "sesame street"
, but not the words
"cookie"
or "monster"
