Acoustic Attenuation in Fans and Ducts by Vaporization of Liquid Droplets [PDF]

open access: yes, 1975
A cloud of small water droplets in saturated air attenuates acoustic disturbances by viscous drag, heat transfer, and vapor exchange with the ambient gas. The viscous and heat transfer phenomena attenuate at frequencies above 104 Hz for I-J.l droplets.

Transient Marangoni convection in hanging evaporating drops [PDF]

open access: yes, 2004
. A combined experimental and numerical analysis has been carried out to study Marangoni effects during the evaporation of droplets. The experiments are performed with pendant drops of silicone oils (with different viscosities) and hydrocarbons.

Matrigel inhibits elongation and drives endoderm differentiation in aggregates of mouse embryonic stem cells

open access: yesFEBS Open Bio, EarlyView.
Stem cell‐based embryo models (SCBEMs) are valuable to study early developmental milestones. Matrigel, a basement membrane matrix, is a critical substrate used in various SCBEM protocols, but its role in driving stem cell lineage commitment is not clearly defined.

Characteristics of droplets formed on the outer surface of the rotating packed bed [PDF]

open access: yesEPJ Web of Conferences
A rotating packed bed (RPB), as a device for mass transfer enhancement, can be divided into three main parts. An eye of a rotor, a packing, and an outer cavity.

Synthesis of Copper Oxide Nanoparticles in Droplet Flow Reactors [PDF]

open access: yes, 2017
Synthesis of metal oxide nanoparticles within droplet flow reactors is advantageous over batch synthesis due to the elimination of concentration and temperature gradients inside the reactor and prevention of reactor fouling.

Slip or not slip? A methodical examination of the interface formation model using two-dimensional droplet spreading on a horizontal planar substrate as a prototype system

open access: yes, 2012
We consider the spreading of a thin two-dimensional droplet on a planar substrate as a prototype system to compare the contemporary model for contact line motion based on interface formation of Shikhmurzaev [Int. J. Multiphas.

Iron‐dependent lysosomal LDL oxidation induces the expression of scavenger receptor A in human THP‐1 monocytes

open access: yesFEBS Open Bio, EarlyView.
In human monocytic cells THP‐1, a limited uptake of native—not oxidized—LDL/VLDL induced expression of scavenger receptor A and cellular adhesion. Induction was inhibited by lysosomotropic (WR‐1065) and lipophilic (BHT) antioxidants and by siRNAs against ferritinophagy.

Numerical Investigation of the Main Characteristics of Heat and Mass Transfer while Heating the Heterogeneous Water Droplet in the Hot Gases

open access: yesEPJ Web of Conferences, 2016
The processes of heat and evaporation of heterogeneous water droplet with solid (by the example of carbon) inclusion in hot (from 800 K to 1500 K) gases were investigated by the developed models of heat and mass transfer.

Numerical analysis of sulfur dioxide absorption in water droplets

open access: yesOpen Physics, 2020
Mass transfer between the phases is a cornerstone of many technological processes and presents a topic whose understanding and modelling is of high importance.

Mechanisms of optical angular momentum transfer to nematic liquid crystalline droplets [PDF]

open access: yes, 2004
A detailed study is presented that evaluates the relative importance of wave plate behavior, scattering processes and absorption phenomena in transferring optical torque from circularly polarized light to optically trapped nematic droplets.
