TL;DR: The feasibility of using two important and common clay minerals, kaolinite and montmorillonite, as adsorbents for removal of toxic heavy metals has been reviewed.

TL;DR: Much research in emulsions can be applied to foam systems, however evidence would suggest foam systems are under a number of additional constraints, and the stability 'window' for particles is smaller, in terms of size and contact angle ranges.

TL;DR: It is evident from the review that low-cost adsorbents have demonstrated high removal capabilities for certain phenolic compounds and industrial waste might be a promising adsorbent for environmental and purification purposes.

TL;DR: In this review two general types of nanoparticle-polymer PV cells are considered and compared in detail, and two sets of assembly conditions that are suggested are suggested for constructing PCBM-P3HT (P3 HT is poly(3-hexylthiophene)) or CdSe-P 3HT PV cells with reasonable power conversion efficiency.

TL;DR: An overview of the recent developments in the area of surfactant enhanced soil and groundwater remediation processes, focusing on micellar solubilization of organic hydrocarbons, and some laboratory and field studies on removal of organics from contaminated soil are reviewed to show the applicability of this technology.

TL;DR: This review introduces and summarizes the fundamentals and various technical approaches developed for the template-based synthesis of nanorod, nanowire and nanotube arrays, and focuses mainly on the most widely used and well established techniques.

TL;DR: The theoretical approach is suggested, which makes it possible to model and characterize the electrochemical properties of heterogeneous membranes using several transport-structural parameters that are extracted from the experimental dependences of specific electroconductivity and diffusion permeability on concentration.

TL;DR: The effect that nanoparticles play in the spreading of nanofluids dynamically wetting and dewetting solid substrates is investigated experimentally, using 'drop shape' analysis technique to analyse aluminium-ethanol contact lines advancing and receding over hydrophobic Teflon-AF coated substrates.

TL;DR: In this paper, the analysis of physico-chemical properties of emulsifier films at fluid interfaces in relation to foaming is presented, and a close relationship is observed between foaming capacity and the rate of diffusion of the foaming agent to the air-water interface.

TL;DR: Differences and similarities between processes taking place in aqueous and organic solvents are highlighted, and the main models currently employed to interpret the results are briefly discussed.

TL;DR: The aim of this contribution is to give a literature overview of interfacial shear rheological studies of pure protein and protein/surfactant mixtures at liquid interfaces measured with different techniques.

TL;DR: Though aimed primarily at confocal microscopy studies of colloidal systems, the methods outlined here should transfer readily to many other feature extraction problems, especially where features may overlap one another.

TL;DR: An overview on some dynamic wetting and spreading phenomena in the presence of surfactants in the case of smooth or porous substrates, which can be either moderately or highly hydrophobic surfaces based on the literature data and the authors own investigations.

TL;DR: An overview on the research on pH-responsive microgel particles in the last 10 years is presented, whose properties display extreme pH sensitivity in water is considered in detail in terms of swelling behavior and rheological properties.

TL;DR: It is shown that the formation of DBL induced by electric current is quasi-stationary, which allows the empirical expression found earlier and linking delta with Delta c under steady-state conditions to be used in transient regimes.

TL;DR: The most important and promising models proposed recently as well as some older theoretical models inspired by the pioneering ideas proposed in the papers of Dubinin, Serpinsky, Barton, D'Arcy, Watt, Do and Do and others are discussed.

TL;DR: This article reviews known approaches to generating viscoelastic and gel-like surfactant systems focusing on how the formation of these viscous phases are often sensitive to a variety of chemical and physio-chemical factors.

TL;DR: The predictions of this generalized free-volume theory of Lekkerkerker et al. are in excellent agreement with experiment and with computer simulations, not only for the colloid limit but also for the protein limit (and the crossover between these limits).

TL;DR: Ormosil-based materials can be used as efficient protective coatings and can be utilized in designing wave guides that can carry out excellent photonic transmission of information.

TL;DR: The effect that the hydrophobic counterion microenvironment has on the phase behavior, rheological behavior and the micellar microstructure is discussed.

TL;DR: It is concluded that the studies of negative rejections could be a valuable membrane characterization tool but they need to be more systematic and targeted to fulfil this role.

TL;DR: This review article presents an overview of relevant microfluidic devices and focuses on their performance with respect to concentrated suspensions, as one finds in food industry, and concludes that deterministic ratchets seem most promising.

TL;DR: It is demonstrated that valuable structural information can be obtained from X-ray and neutron scattering characterisation of complex systems containing periodic phases with d-spacing values up to 30 nm, and that both techniques are powerful means for in situ monitoring of the formation of nanostructured materials.

TL;DR: The "titanium oxide/electrolyte solution" interface is studied by taking in advantage the recent developments in the field of Surface and Interface Chemistry relevant to this oxide by derived the three most probable surface ionization models.

TL;DR: The aim of this paper is to give a perspective and critical overview of studies carried out to date on the mass transfer of gas through foam films, and to highlight the gaps and challenges and sketch possible directions for future research.

TL;DR: The present review surveys and generalizes the previous investigations and proposes a new theory of asymmetry of diffusion permeability of bi-layer membranes, which has been deduced explicit algebraic formulas for the degree of asymmetrical permeability in the model of "homogeneous porous membrane".

TL;DR: Interestingly, a "skin-like" folded film of pure protein or phospholipid/protein complex layers can be observed at curved surfaces at the water/oil interfaces.

TL;DR: The paper gives a review of publications on polymers with conjugated matrices which incorporate metallocene complexes with two cyclopentadienyl ligands and their derivatives, as well as hemi-metallocenecomplex complexes, as pendant groups or inside the principal chain.

TL;DR: The present article reviews the results obtained so far and covers the aspects of their synthesis, properties in bulk (solutions and solid state) and applications, with special emphasis on the Langmuir monolayer properties and self-organization of SFAs on solid substrates.

TL;DR: By far the most promising systems, from the point of view of constructing polyelectrolyte multilayers onliposome cores without disruption of liposome integrity, involve small, liquid, anionic liposomes coated initially with polycations carrying pendant alkyl groups.
