Modeling of Masked Droplet Deposition for Site-Controlled Ga Droplets. [PDF]

open access: yesNanomaterials (Basel), 2023
Site-controlled Ga droplets on AlGaAs substrates are fabricated using area-selective deposition of Ga through apertures in a mask during molecular beam epitaxy (MBE). The Ga droplets can be crystallized into GaAs quantum dots using a crystallization step under As flux.

Distribution characteristics on droplet deposition of wind field vortex formed by multi-rotor UAV. [PDF]

open access: yesPLoS ONE, 2019
When the unmanned aerial vehicle (UAV) is used for aerial spraying, the downwash airflow generated by the UAV rotor will interact with the crop canopy and form a conical vortex shape in the crop plant.

Enhancing droplet deposition through in-situ precipitation. [PDF]

open access: yesNat Commun, 2016
AbstractRetention of agricultural sprays on plant surfaces is an important challenge. Bouncing of sprayed pesticide droplets from leaves is a major source of soil and groundwater pollution and pesticide overuse. Here we report a method to increase droplet deposition through in-situ formation of hydrophilic surface defects that can arrest droplets ...

Effect of formulations and adjuvants on the properties of acetamiprid solution and droplet deposition characteristics sprayed by UAV [PDF]

open access: yesFrontiers in Plant Science
While the pesticide formulations are widely used for pest control, the combined effects of these formulations with adjuvants on droplet behavior, spraying characteristics, and pest control still need to be studied.
