Protein adsorption to solids, nanomaterials, and biological surfaces is of central interest in many fields, including biomedicine, bioanalytical chemistry, materials engineering, bio-nanotechnology, and basic biomolecular research. Although protein adsorption may sometimes occur with little consequence on molecular structure, interactions with surfaces frequently cause changes in local or global conformations and dynamics, perturbations to secondary structures or tertiary folds, eventually resulting in dramatically altered protein function. Importantly, surfaces may trigger protein misfolding and self-aggregation, or, conversely, promote protein structure formation. The use of nanoscale surfaces to remodel the conformational landscape and the aggregation pathways of amyloidogenic peptides and proteins has been proposed as a promising strategy against several severe human diseases. The rapid growth of applications and technological innovation which is based on or concerned with protein adsorption necessitates renewed efforts to provide molecular-level insights into adsorption-induced protein structural perturbations. In this Special Issue, we gathered the recent findings of experimental and computational investigations that contributed novel insights into protein adsorption with a focus on the structural and dynamic aspects of proteins.

Unit metallurgical operations processes are usually separated into three categories: 1) hydrometallurgy (leaching, mixing, neutralization, precipitation, cementation, and crystallization); 2) pyrometallurgy (roasting and smelting); and 3) electrometallurgy (aqueous electrolysis and molten salt electrolysis). In hydrometallurgy, the aimed metal is first transferred from ores and concentrates to a solution using a selective dissolution (leaching or dry digestion) under an atmospheric pressure below 100 °C and under a high pressure (40-50 bar) and high temperature (below 270°C) in an autoclave. The purification of the obtained solution was performed using neutralization agents such as sodium hydroxide and calcium carbonate or more selective precipitation agents such as sodium carbonate and oxalic acid. The separation of metals is possible using a liquid/liquid process (solvent extraction in mixer-settler) and solid–liquid (filtration in filter-press under high pressure). Crystallization is the process by which a metallic compound is converted from a liquid into a solid crystalline state via a supersaturated solution. The final step is metal production using electrochemical methods (aqueous electrolysis for basic metals such as copper, zinc, silver, and molten salt electrolysis for rare earth elements and aluminum). Advanced processes, such as ultrasonic spray pyrolysis and microwave-assisted leaching, can be combined with reduction processes in order to produce metallic powders.

Due to their unique size-dependent physicochemical properties, nanostructured thin films are used in a wide range of applications from smart coating and drug delivery to electrocatalysis and highly-sensitive sensors. Depending on the targeted application and the deposition technique, these materials have been designed and developed by tuning their atomic-molecular 2D- and/or 3D-aggregation, thickness, crystallinity, and porosity, having effects on their optical, mechanical, catalytic, and conductive properties. Several open questions remain about the impact of nanomaterial production and use on environment and health. Many efforts are currently being made not only to prevent nanotechnologies and nanomaterials from contributing to environmental pollution but also to design nanomaterials to support, control, and protect the environment. This Special Issue aims to cover the recent advances in designing nanostructured films focusing on environmental issues related to their fabrication processes (e.g., low power and low cost technologies, the use of environmentally friendly solvents), their precursors (e.g., waste-recycled, bio-based, biodegradable, and natural materials), their applications (e.g., controlled release of chemicals, mimicking of natural processes, and clean energy conversion and storage), and their use in monitoring environment pollution (e.g., sensors optically- or electrically-sensitive to pollutants)
