Abstract

Die industrielle Herstellung anorganischer nanoskaliger und nanostrukturierter Partikel erfolgt vorwiegend durch den Einsatz physikalischer und chemischer Verfahren. Im Rahmen dieser Arbeit wird gezeigt, dass durch Verwendung sog. Biomineralisationsprozesse eine relativ große Anzahl qualitativ hochwertiger Partikel zu wirtschaftlich interessanten Konditionen herstellbar ist. Im Vgl. zu Partikeln aus physikalischchemischen Verfahren besitzen biogene Partikel weitere interessante Eigenschaften.

Abstract

Precious metals continue to have economic and sociocultural importance, as their usage evolves and diversifies over time. Today, the industrial application of precious metals is increasing with the development of scientific and technological innovations. Especially, the biological cycling of these metals is receiving more and more attention, as the microbiota may be key to a range of issues regarding exploration, ore-processing and metallurgy, and the processing of electron waste. In this volume, we focus on enhancing the fundamental understanding of the biological processes that drive noble metal cycling and examine how this knowledge may be turned into biotechnolical applications.

Abstract

Reactions at mineral surfaces are central to all geochemical processes. As minerals comprise the rocks of the Earth, the processes occurring at the mineral–aqueous fluid interface control the evolution of the rocks and hence the structure of the crust of the Earth during processes such as metamorphism, metasomatism, and weathering. In recent years focus has been concentrated on mineral surface reactions made possible through the development of advanced analytical methods such as atomic force microscopy (AFM), advanced electron microscopies (SEM and TEM), phase shift interferometry, confocal Raman spectroscopy, and advanced synchrotron-based applications, to enable mineral surfaces to be imaged and analyzed at the nanoscale. Experiments are increasingly complemented by molecular simulations to confirm or predict the results of these studies. This has enabled new and exciting possibilities to elucidate the mechanisms that govern mineral–fluid reactions. In this Special Issue, “Mineral Surface Reactions at the Nanoscale”, we present 12 contributions that highlight the role and importance of mineral surfaces in varying fields of research.
