Contact line and contact angle dynamics in superhydrophobic channels.

Langmuir : the ACS journal of surfaces and colloids

Zhang J, Kwok DY.
PMID: 16700586
Langmuir. 2006 May 23;22(11):4998-5004. doi: 10.1021/la053375c.

The dynamics of the wetting and movement of a three-phase contact line confined between two superhydrophobic surfaces were studied using a mean-field free-energy lattice Boltzmann model. Principle features of superhydrophobic surfaces, such as trapped vapor/air between rough microstructures, high...

Hydrodynamics from statistical mechanics: combined dynamical-NEMD and conditional sampling to relax an interface between two immiscible liquids.

We present a method to study hydrodynamic phenomena from atomistic simulations. In statistical mechanics, these fields are computed as the ensemble average over the time dependent probability density function corresponding to the time evolution of an initial conditional probability...

Capitalizing on the hydrophobic bias of electrospray ionization through chemical modification in mass spectrometry-based proteomics.

Expert review of proteomics

PMID: 21679113
Expert Rev Proteomics. 2011 Jun;8(3):317-23. doi: 10.1586/epr.11.24.

Protein chemical derivatization has emerged as an invaluable bioanalytical approach in mass spectrometry-based proteomics with nearly unlimited potential. To date, derivatization strategies in proteomics have primarily focused on improving mass spectral identification and relative quantification of proteins, as well...

Polarity-based fractionation in proteomics: hydrophilic interaction vs reversed-phase liquid chromatography.

Biomedical chromatography : BMC

Jafari M, Mirzaie M, Khodabandeh M, Rezadoost H, Ghassempour A, Aboul-Enein HY.
PMID: 26555197
Biomed Chromatogr. 2016 Jul;30(7):1036-1041. doi: 10.1002/bmc.3647. Epub 2015 Dec 06.

During recent decades, hydrophilic interaction liquid chromatography (HILIC) ahs been introduced to fractionate or purify especially polar solutes such as peptides and proteins while reversed-phase liquid chromatography (RPLC) is also a common strategy. RPLC is also a common dimension...

The Structural and Dynamical Properties of the Hydration of SNase Based on a Molecular Dynamics Simulation.

Molecules (Basel, Switzerland)

PMID: 34500836
Molecules. 2021 Sep 05;26(17). doi: 10.3390/molecules26175403.

The dynamics of protein-water fluctuations are of biological significance. Molecular dynamics simulations were performed in order to explore the hydration dynamics of staphylococcal nuclease (SNase) at different temperatures and mutation levels. A dynamical transition in hydration water (at ~210...

The role of alpha-helix on the structure-targeting drug design of amyloidogenic proteins.

The most accredited hypothesis links the toxicity of amyloid proteins to their harmful effects on membrane integrity through the formation of prefibrillar-transient oligomers able to disrupt cell membranes. However, damage mechanisms necessarily assume a first step in which the...

Thermo-responsive polymeric nanoparticles (NPs) are emerging as a powerful tool in nanomedicine for the fabrication of advanced drug delivery systems. In addition to their size and biodegradation rate, phase separation of NPs upon application of a thermal stimulus provides...

[Stationary phases for hydrophilic interaction liquid chromatography and their applications in separation of traditional Chinese medicines].

Se Pu. 2009 Sep;27(5):675-81.

Hydrophilic interaction liquid chromatography (HILIC) is an alternative of reversed-phase liquid chromatography (RPLC) for the separation of polar compounds. The main characteristic of HILIC is the use of polar stationary phases and aqueous/organic (usually acetonitrile) mobile phases. In recent...

Cassie and Wenzel: were they really so wrong?.

Langmuir : the ACS journal of surfaces and colloids

McHale G.

The properties of superhydrophobic surfaces are often understood by reference to the Cassie-Baxter and Wenzel equations. Recently, in a paper deliberately entitled to be provocative, it has been suggested that these equations are wrong; a suggestion said to be...
