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.

Deposition And Drying Dynamics Of Liquid Crystal Droplets [PDF]

open access: yesNature Communications, 2017
Drop drying and deposition phenomena reveal a rich interplay of fundamental science and engineering, give rise to fascinating everyday effects (coffee rings), and influence technologies ranging from printing to genotyping. Here we investigate evaporation

Droplet Deposition Distribution Prediction Method for a Six-Rotor Plant Protection UAV Based on Inverse Distance Weighting [PDF]

open access: yesSensors, 2022
The aim of this work is to establish a method for real-time calculating droplet deposition distribution of a six-rotor plant protection unmanned aerial vehicle (UAV). The numerical simulation of the airflow field was carried out using computational fluid

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 ...

Evaluation of droplet deposition parameters based on the Genetic-Otsu algorithm [PDF]

open access: yesPeerJ
Pesticide spraying is a cost-effective way to control crop pests and diseases. The effectiveness of this method relies on the deposition and distribution of the spray droplets within the targeted application area. There is a critical need for an accurate

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.

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.

Subarachnoidal fat droplet deposition and fat embolism syndrome. [PDF]

open access: yesBMJ Case Rep, 2017
A 68-year-old woman presenting with multiple rib, spine fractures, femur and ankle fractures after a fall from height was admitted. Although she responded to verbal orders appropriately at the time of admission, her consciousness drastically deteriorated after 4.5 hours of the accident.

Spherical Droplet Deposition—Mechanistic Model [PDF]

open access: yesCoatings, 2021
In the currently existing physical models of wetting a solid substrate by a liquid drop, the contact angle is determined on the basis of the equilibrium of forces acting tangentially to the wetted surface at any point in the perimeter of the wetted area, ignoring the forces (or their components) acting perpendicular to this area.
