Open AccessEffect of internal structure and resin deformability on drying rate and stress in convective drying of silica–latex coatings
Latex paint is an aqueous dispersion of nano-sized polymer particles that can form a thin film by itself or mixed with rigid particles. We have developed an apparatus that can simultaneously measure drying rat...

Open AccessAssessment of bone tissue cytoarchitectonics by 2D 1H NMR relaxometry maps
Bone is a complex tissue that fulfills the role of a resistance structure. This quality is most commonly assessed by bone densitometry, but bone strength may not only be related to bone mineral density but als...

Open AccessA microfluidic platform for the synthesis of polymer and polymer-protein-based protocells
In this study, we demonstrate the fabrication of polymersomes, protein-blended polymersomes, and polymeric microcapsules using droplet microfluidics. Polymersomes with uniform, single bilayers and controlled d...

Open AccessTexture identification in liquid crystal-protein droplets using evaporative drying, generalized additive modeling, and K-means Clustering
Sessile drying droplets manifest distinct morphological patterns, encompassing diverse systems, viz., DNA, proteins, blood, and protein-liquid crystal (LC) complexes. This study employs an integrated methodolo...

Open AccessDroplet motion driven by humidity gradients during evaporation and condensation
The motion of droplets on solid surfaces in response to an external gradient is a fundamental problem with a broad range of applications, including water harvesting, heat exchange, mixing and printing. Here we...

Open AccessAsymptotic analysis of particle cluster formation in the presence of anchoring sites
The aggregation or clustering of proteins and other macromolecules plays an important role in the formation of large-scale molecular assemblies within cell membranes. Examples of such assemblies include lipid ...

Open AccessA multiple-timing analysis of temporal ratcheting
We develop a two-timing perturbation analysis to provide quantitative insights on the existence of temporal ratchets in an exemplary system of a particle moving in a tank of fluid in response to an external vi...

Open AccessA hard sphere model for single-file water transport across biological membranes
We use Gürsey’s statistical mechanics of a one-dimensional fluid to find a formula for the \(P_\textrm{f}/P_\textrm{d}\) ...

Open AccessFree surface oscillation driven by rotating stirrer
To gain insights into the mechanisms of free surface oscillation in a rotating mixing container, we observe the free surface deformation and measure the torque acting on the bar. The container was half-filled ...

Open AccessModeling and correction of image drift in dynamic shadowgraphy experiments
The study of phoretic transport phenomena under non-stationary conditions presents several challenges, mostly related to the stability of the experimental apparatus. This is particularly true when investigatin...

Article
Open AccessQuantitative comparison of cell–cell detachment force in different experimental setups
We compare three different setups for measuring cell–cell adhesion. We show that the measured strength depends on the type of setup that is used. For identical cells different assays measure different detachme...

Open AccessMechanical convergence in mixed populations of mammalian epithelial cells
Tissues consist of cells with different molecular and/or mechanical properties. Measuring the forces and stresses in mixed-cell populations is essential for understanding the mechanisms by which tissue develop...

Open AccessVibrational spectrum of Granular packings with random matrices
The vibrational spectrum of granular packings can be used as a signature of the jamming transition, with the density of states at zero frequency becoming nonzero at the transition. It has been proposed previou...

Open AccessMicrorheological comparison of melanoma cells by atomic force microscopy
Melanoma is one of the most severe cancers due to its great potential to form metastasis. Recent studies showed the importance of mechanical property assessment in metastasis formation which depends on the cyt...

Open AccessMechanosensitivity of phase separation in an elastic gel
Liquid–liquid phase separation (LLPS) in binary or multi-component solutions is a well-studied subject in soft matter with extensive applications in biological systems. In recent years, several experimental st...

Open AccessMany-body interactions between contracting living cells
The organization of live cells into tissues and their subsequent biological function involves inter-cell mechanical interactions, which are mediated by their elastic environment. To model this interaction, we ...

Open AccessFrom isolated polyelectrolytes to star-like assemblies: the role of sequence heterogeneity on the statistical structure of the intrinsically disordered neurofilament-low tail domain
Intrinsically disordered proteins (IDPs) are a subset of proteins that lack stable secondary structure. Given their polymeric nature, previous mean-field approximations have been used to describe the statistic...
