Release of Encapsulated Content in Microdroplets

open access: yesAnalytical Sciences, 2011
A method for releasing the content of microdroplets by changing the channel wall wettability is proposed. The contents of aqueous droplets were released to the continuous phase by inverting 10-µm-sized W/O droplets into O/W ones in a 2-µm-deep hydrophilic channel. The combination of "encapsulation" and "release" in microdroplets facilitates micromixing

Evaporation of Microdroplets of Azeotropic Liquids [PDF]

open access: yesThe Journal of Physical Chemistry B, 2000
This work reports data showing the evolution of contact angle with time for mixtures of water and 1-propanol at room temperature on poly(methyl methacrylate) (PMMA). The composition range investigated spans the azeotropic composition, thus encompassing systems containing excess water and excess 1-propanol.

Microdroplet-Mediated Radical Polymerization

open access: yesACS Central Science, 2022
Micrometer-sized aqueous droplets serve as a unique reactor that drives various chemical reactions not seen in bulk solutions. However, their utilization has been limited to the synthesis of low molecular weight products at low reactant concentrations (nM to μM).

Interfacial thermal conductance of 7075 aluminum alloy microdroplets in contact with a solid at fast melting and crystallization

open access: yesMaterials Research Express, 2022
Ultrafast nanocalorimetry, in combination with high-speed IR thermography, is used to measure the interfacial thermal conductance (ITC) of the thermal contact of metal microdroplets with a solid during fast melting (including laser heating).

Investigation of the Phase‐Separation Point During CO2 Absorption in the DETA–Sulfolane–Water System

open access: yesCarbon and Hydrogen, EarlyView.
Optical scattering diagnostics combined with generalized solubility product modeling enables quantitative prediction of phase separation in DETA–sulfolane–water biphasic CO2 absorbents. ABSTRACT The phase‐separation behavior of liquid–liquid biphasic amine absorbents is typically identified using bubbling reactors, where visual observation is employed ...
