TL;DR: In this article, the effect of constituents on structure, flow, and thermal properties of nanoscale ionic materials (NIMs) is discussed, and a new class of nanohybrids consisting of a nanometer-sized core, a charged corona covalently attached to the core, and an oppositely charged canopy is introduced.
Abstract: In this article we discuss the effect of constituents on structure, flow, and thermal properties of nanoscale ionic materials (NIMs). NIMs are a new class of nanohybrids consisting of a nanometer-sized core, a charged corona covalently attached to the core, and an oppositely charged canopy. The hybrid nature of NIMs allows for their properties to be engineered by selectively varying their components. The unique properties associated with these systems can help overcome some of the issues facing the implementation of nanohybrids to various commercial applications, including carbon dioxide capture, water desalinization and as lubricants.

TL;DR: In this paper, the authors investigated the solvent vapor annealing process of a model insoluble molecular semiconductor thin film (pentacene on SiO2 exposed to acetone vapor) using a combination of optical reflectance and two-dimensional grazing incidence X-ray diffraction measurements performed in situ, during processing, and demonstrated that solvent molecules interact mainly with the surface of the film to induce a solid-solid transition without noticeable swelling, dissolving or melting of the molecular material.
Abstract: Solvent vapor annealing has been proposed as a low-cost, highly versatile, and room-temperature alternative to thermal annealing of organic semiconductors and devices. In this article, we investigate the solvent vapor annealing process of a model insoluble molecular semiconductor thin film—pentacene on SiO2 exposed to acetone vapor—using a combination of optical reflectance and two-dimensional grazing incidence X-ray diffraction measurements performed in situ, during processing. These measurements provide valuable and new insight into the solvent vapor annealing process; they demonstrate that solvent molecules interact mainly with the surface of the film to induce a solid–solid transition without noticeable swelling, dissolving or melting of the molecular material.
