Controllable Formation and Real-Time Characterization of Single Microdroplets Using Optical Tweezers

open access: yesMicromachines, 2022
Existing preparation methods for microdroplets usually require offline measurements to characterize single microdroplets. Here, we report an optical method used to facilitate the controllable formation and real-time characterization of single ...

Threshold magnetic field as a universal criterion for the selective transport of magnetized particles in microdroplets

open access: yesScientific Reports, 2023
Transportation of magnetized particles (MPs) against gravity is possible by applying a magnetic field to the particles. This transport phenomenon of MPs in microdroplets can be quantitatively assessed by determining the contribution of individual forces ...

Electrochemical Formation Mechanism of Microdroplets on Pure Iron

open access: yesFrontiers in Chemistry, 2021
The electrochemical formation mechanism of microdroplets formed around a primary droplet of 3.5% NaCl solution on an iron-plated film was investigated by quartz crystal microbalance (QCM) and concentric three-electrode array (CTEA) measurements.

Structure and composition of thin GaAs1-x-yNxBiy films produced by pulsed laser deposition

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2022
Uniaxial cold pressing was used to fabricate GaAs0,9Bi0,1 targets with 10% Bi content. Thin films of GaAs1-x-yNxBiy onto a GaAs (100) substrate were obtained from the formed GaAs0,9Bi0,1 target by pulsed laser deposition in an argon-nitrogen gas ...

Kinetic Study of the Maillard Reaction in Thin Film Generated by Microdroplets Deposition

open access: yesMolecules, 2022
The Maillard reaction kinetics in the confined volume of the thin film produced by ESI microdroplet deposition was studied by mass spectrometry. The almost exclusive formation of the Amadori product from the reaction of D-xylose and D-glucose toward L ...

Enhancement of solute diffusion in microdroplets using microrotors under rotational magnetic field

open access: yesScientific Reports, 2023
In vertical contact control (VCC), a microdroplet array selectively contacts with an opposite microdroplet array. Generally, VCC is useful for the dispenser mechanism based on solute diffusion between microdroplet pairs.

Hammett Correlation in the Accelerated Formation of 2,3-Diphenylquinoxalines in Nebulizer Microdroplets

open access: yesMolecules, 2021
The accelerated formation of 2,3-diphenylquinoxalines in microdroplets generated in a nebulizer has been investigated by competition experiments in which equimolar quantities of 1,2-phenylenediamine, C6H4(NH2)2, and a 4-substituted homologue, XC6H3(NH2)2

Distinguishing between Isobaric Ions Using Microdroplet Hydrogen–Deuterium Exchange Mass Spectrometry

open access: yesMetabolites, 2021
Isobaric ions having the same mass-to-charge ratio cannot be separately identified by mass spectrometry (MS) alone, but this limitation can be overcome by using hydrogen–deuterium exchange (HDX) in microdroplets.

Spontaneous Oxidation and Hydration of Aromatic Aldehydes in Microdroplets and its Atmospheric Implications [PDF]

open access: yesZhipu Xuebao, 2023
Microdroplets have many unique features derived from the large surface-volume ratio and the ultrahigh electric field at the air-water interface, therefore they can remarkably accelerate various slow reactions and trigger reactions that won’t occur in ...
