TL;DR: This paper presents a review of the published articles for a period of approximately 120 years related to the evaporation of both sessile drops and nearly spherical droplets suspended from thin fibers.

TL;DR: The mechanisms and theories suggested in the literature to explain the impact of oil on foam stability in the bulk and porous media are reviewed and various ideas on an improvement of foam stability and longevity in the presence of oil are presented.

TL;DR: It is concluded that only the nanocluster model is capable of accounting for the experimental scattering contrast variation data and all features and trends are predicted self consistently.

TL;DR: An outline of the suite of roughness characterization parameters that are available for the comprehensive description of the surface architecture of a substratum is presented, and a set of topographical parameters is proposed as a new standard for surface Roughness characterization in bacterial adhesion studies to improve the likelihood of identifying direct relationships between substratum topography and the extent of bacterial ad cohesion.

TL;DR: Predictive curves of fundamental rheological properties (viscosity, yield stress, elastic and complex moduli) vs. particle volume fraction and shear rate were obtained from theoretical or empirical models and sound experimental data, covering ranges of practical interest.

TL;DR: An overview of recent advances in the field of nanofluids, especially the important material properties that affect the thermal properties of nan ofluids and novel approaches to achieve extremely high thermal conductivities are provided.

TL;DR: It is shown that for surfaces wet with a composite interface, the commonly used form of the Cassie-Baxter equation, cosθ(c)=f(1)cosθ-(1-f), is only correct for the case of flat topped pillar geometry without any penetration of the liquid.

TL;DR: This review is devoted to silica-noble metal core-shell nanostructures and outlines the main methods used for the preparation and surface modification ofsilica particles and presents the major strategies for the formation of metal nanoshells on the modified silica particles.

TL;DR: This review presents a comprehensive description of the F-mediated synthesis and unique properties of fluorinated semiconductor photocatalysts, in particular titanium dioxide (TiO(2).

TL;DR: The dielectric constants inside the nanopore are calculated and these values were consistent for three of the salts studied, indicating that a simplistic model based on Born theory is accurate enough for engineering calculations and that ion solvation is most likely to be the more appropriate dielectrics exclusion mechanism for true nanofiltration membranes.

TL;DR: It is concluded that microbubble shells collapse through the nucleation of microscopic folds, which then catalyze the formation and aggregation of new folds, leading to macroscopic folding events, which results in a cyclic behavior of crumple-to-smooth transitions.

TL;DR: The results indicate that the micelles of greater aggregation number have a lower degree of ionization, which can be explained with the effect of counterion binding.

TL;DR: The surface characteristics, including surface charge and wettability, of layered silicates are reviewed and the wetting characteristics of the silica tetrahedral surface are examined with different experimental techniques and results are discussed.

TL;DR: An extensive overview of the main principles and the recent progress made in the synthesis of ordered mesoporous phenolic resins and carbons using the soft-template method are given.

TL;DR: Porous silicon (pSi) has a number of unique properties that appoint it as a potential drug delivery vehicle; high loading capacity, controllable surface chemistry and structure, and controlled release properties, which allows specific drug release behaviors to be engineered to aid in the delivery of previously challenging therapeutics.

TL;DR: In this study, a consideration of the physicochemical processes accompanying the contact of hydrophobic and superhydrophobic materials with water, acid, alkaline and saline aqueous solutions is presented on the basis of experimental data on three-phase equilibrium obtained by the sessile drop method.

TL;DR: The presence of surfactant and frother in water was found to be beneficial for generating a larger number of submicron size bubbles that are more stable, having a life time of up to 24h.

TL;DR: This review clearly demonstrates that the biological route to inorganic materials synthesis is not merely an addition to the existing list of synthesis routes; biological routes using 'unusual' microorganisms might in fact provide an edge over other nanomaterials synthesis routes in terms of their eco-friendliness, low energy intensiveness, and economically-viable synthesis.

TL;DR: The very mechanism of foam generation whose product is initial foam generation, the elastic modulus of the foam bubbles is responsible for the further "life" of the already generated foam, was scrutinized.

TL;DR: Direct force measurements used to obtain a comprehensive picture of interaction forces acting between charged colloidal particles in the presence of oppositely charged polyelectrolytes conclude that bridging forces are unimportant in these systems.

TL;DR: Here, suitable modifications of the experimental procedure and the referred theoretical approach are implemented in order to calculate the values of the stability ratio and the flocculation rate corresponding to a dodecane-in-water nanoemulsion stabilized with sodium dodecyl sulfate.

TL;DR: It is confirmed that the neglecting of hydrodynamic interaction results in an accelerated growth of aggregates and the results of numerical simulations of aggregation kinetics are compared with well known analytical solutions.

TL;DR: The characterization of low-energy surfaces is discussed as these surfaces are important for electrowetting on a dielectric (EWOD) and the characterization methods reveal that both dispersion and acid-base interactions areImportant for wetting.

TL;DR: In this paper, the authors give an overview of the many opportunities that arise from approaching food structuring from the perspective of soft matter physics, such as free volume, the mean field, and effective temperatures.

TL;DR: It seems that IEP is more suitable than PZC as the unique number characterizing the pH-dependent surface charging of materials other than metal oxides.

TL;DR: Results from both experimental measurements and molecular dynamics simulations consistently indicate that structural ordering of alkyl chains in SAMs reduces their frictional response, and that SAMs formed by molecules with alkyL chains longer than 8 to 10 methylene units are well organized, exhibiting low levels of friction.
