“…This entropy-driven stabilization has been used in most hydrophobic nanomaterial ink. [90] In hydrophilic dispersions, charged polymers are often used to combine the electrostatic and the steric stabilization (electrosteric stabilization). [91] Even when the nanoparticle dispersion in the solution phase is stable, the particles can aggregate during the coating process or the thermal annealing process.…”

“…Currently, the active materials for high device performance are inorganic materials. [ 85–120 ] Because the inorganic materials have a small strain at break ( ε b ) (typically, ε b < 1%), their composites with elastomeric polymers have been used to obtain stretchability. In the inorganic–organic nanocomposites, homogeneous spatial distribution of the inorganic fillers and strong filler–matrix adhesion is important to secure the mechanical electrical stability under repeated cycles of large strains.…”

Stretchable electronics has emerged over the past decade and is now expected to bring form factor-free innovation in the next-generation electronic devices. Stretchable devices have evolved with the synthesis of new soft materials and new device architectures that require significant deformability while maintaining the high device performance of the conventional rigid devices. As the mismatch in the mechanical stiffness between materials, layers, and device units is the major challenge for stretchable electronics, interface control in varying scales determines the device characteristics and the level of stretchability. This article reviews the recent advances in interface control for stretchable electronic devices. It summarizes the design principles and covers the representative approaches for solving the technological issues related to interfaces at different scales: i) nano-and microscale interfaces between materials, ii) mesoscale interfaces between layers or microstructures, and iii) macroscale interfaces between unit devices, substrates, or electrical connections. The last section discusses the current issues and future challenges of the interfaces for stretchable devices.

“…The mechanisms of molecular transport through membranes have been widely studied on both theoretical and experimental levels by many researchers [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. Various theoretical models of molecule transport through membrane channels have been proposed [ 2 , 8 , 9 , 10 , 11 , 12 , 13 ]. These models take into account both the geometric parameters of the membrane channel [ 10 ], binding sites of transported particles inside the channel [ 3 , 7 ], and various types of channel-solute interactions [ 7 , 8 ].…”

The study of drugs diffusion through different biological membranes constitutes an essential step in the development of new pharmaceuticals. In this study, the method based on the monolayer cell culture of CHO-K1 cells has been developed in order to emulate the epithelial cells barrier in permeability studies by laser interferometry. Laser interferometry was employed for the experimental analysis of nickel(II) and cobalt(II) complexes with 1-allylimidazole or their chlorides’ diffusion through eukaryotic cell monolayers. The amount (mol) of nickel(II) and cobalt(II) chlorides transported through the monolayer was greater than that of metals complexed with 1-allylimidazole by 4.34-fold and 1.45-fold, respectively, after 60 min. Thus, laser interferometry can be used for the quantitative analysis of the transport of compounds through eukaryotic cell monolayers, and the resulting parameters can be used to formulate a mathematical description of this process.

In cell biology, the presence of different nano-sized molecular scaffolds in the extracellular matrix environment implies a vast diversity of cellular activities and responses, including uncorrelated diverging drug delivery efficiencies [ 28 ].…”

Entropy and Random Walk Trails Water Confinement and Non-Thermal Equilibrium in Photon-Induced Nanocavities

et al. 2020

View full text Add to dashboard Cite

Molecules near surfaces are regularly trapped in small cavitations. Molecular confinement, especially water confinement, shows intriguing and unexpected behavior including surface entropy adjustment; nevertheless, observations of entropic variation during molecular confinement are scarce. An experimental assessment of the correlation between surface strain and entropy during molecular confinement in tiny crevices is difficult because strain variances fall in the nanometer scale. In this work, entropic variations during water confinement in 2D nano/micro cavitations were observed. Experimental results and random walk simulations of water molecules inside different size nanocavitations show that the mean escaping time of molecular water from nanocavities largely deviates from the mean collision time of water molecules near surfaces, crafted by 157 nm vacuum ultraviolet laser light on polyacrylamide matrixes. The mean escape time distribution of a few molecules indicates a non-thermal equilibrium state inside the cavity. The time differentiation inside and outside nanocavities reveals an additional state of ordered arrangements between nanocavities and molecular water ensembles of fixed molecular length near the surface. The configured number of microstates correctly counts for the experimental surface entropy deviation during molecular water confinement. The methodology has the potential to identify confined water molecules in nanocavities with life science importance.
