“…It is worth noting that a band associated with glycosidic bonds in α-chitin standard is shifted in the spectrum of chitin/Fe 2 O 3 from 896 cm -1 to 891 cm -1 . This shift is a clear example of hydrogen bond formation between chitin and Fe 2 O 3 ; and is similar to that seen previously for chitin-silica [54][55] and chitin zirconia composites [5]. Additionally, the observed shifts of amide II bands is probably are the result of the degradation of hydrogen bonds responsible for the macromolecular organization of chitin which are presumably disrupted upon hematite incorporation (Figures 4 and 6).…”

“…The thermal stability of chitin under hydrothermal conditions and the presence of various functional groups (-OH and C=O and -NH) in the chitin molecule permit the utilization of this biopolymer in hydrothermal synthesis reactions. Our previously published experimental results showed strong evidence [5][6][7][8][9] that this is a key way to use chitinous matrices of sponge origin as a nanostructured biological scaffold [26][27][28]. A broad variety of reactions related to hydrothermal synthesis can be performed in vitro.…”

range of uses. Here, chitin-based scaffolds isolated from the skeleton of marine demosponge Aplysina aerophoba were used as a template for the in vitro formation of iron oxide from a saturated iron(III) chloride solution, under hydrothermal conditions (pH~1.5, 90 °C). The resultant chitin-Fe 2 O 3 three dimensional composites, prepared for the first time via hydrothermal synthesis route, were thoroughly characterized using light, fluorescence and scanning electron microscopy; as well as with analytical methods like Raman spectroscopy, electron diffraction and HR-TEM. The results show that this versatile method allows for efficient chitin mineralization with respect to hematite. Additionally, we demonstrate that chitin nanofibers template the nucleation of uniform Fe 2 O 3 nanocrystals.

Abstract:In this mini-review, we shall first cover a short history of the discovery of chitin isolated from sponges; as well as its evolutionarily ancient roots. Next, we will delve into the unique structural, mechanical, and thermal properties of this naturally occurring polymer to illuminate how its physicochemical properties may find uses in diverse areas of the material sciences. We show how the unique properties and morphology of sponge chitin renders it quite useful for the new route of "Extreme Biomimetics"; where high temperatures and pressures allow a range of interesting bioinorganic composite materials to be made. These new biomaterials have electrical, chemical, and material properties that have applications in water filtration, medicine, catalysis, and biosensing. OPEN ACCESSPolymers 2015, 7 236

“…Especially sponges of the Verongida Order possess unique nanostructured chitinous skeletons, whose porosity, huge surface area, mechanical properties and thermostability up to 360°C can be attractive for the development of porous separator membranes. First experiments have shown successful functionalization of the chitin scaffolds of poriferan origin utilizing nanophase-ZrO 2 precursors at 150°C [76,77] as well as ZnO at 70°C [78]. Moreover, in vitro silicification of these scaffolds under hydrothermal synthesis conditions (120°C) lead to the development of novel nanostructured composite materials [79,80].…”

Abstract. Besides a continuous increase of the worldwide use of electricity, the electric energy storage technology market is a growing sector. At the latest since the German energy transition ("Energiewende") was announced, technological solutions for the storage of renewable energy have been intensively studied. Storage technologies in various forms are commercially available. A widespread technology is the electrochemical cell. Here the cost per kWh, e. g. determined by energy density, production process and cycle life, is of main interest. Commonly, an electrochemical cell consists of an anode and a cathode that are separated by an ion permeable or ion conductive membranethe separator -as one of the main components. Many applications use polymeric separators whose pores are filled with liquid electrolyte, providing high power densities. However, problems arise from different failure mechanisms during cell operation, which can affect the integrity and functionality of these separators. In the case of excessive heating or mechanical damage, the polymeric separators become an incalculable security risk. Furthermore, the growth of metallic dendrites between the electrodes leads to unwanted short circuits. In order to minimize these risks, temperature stable and non-flammable ceramic particles can be added, forming so-called composite separators. Full ceramic separators, in turn, are currently commercially used only for high-temperature operation systems, due to their comparably low ion conductivity at room temperature. However, as security and lifetime demands increase, these materials turn into focus also for future room temperature applications. Hence, growing research effort is being spent on the improvement of the ion conductivity of these ceramic solid electrolyte materials, acting as separator and electrolyte at the same time. Starting with a short overview of available separator technologies and the separator market, this review focuses on ceramic-based separators. Two prominent examples, the lithium-ion and sodium-sulfur battery, are described to show the current stage of development. New routes are presented as promising technologies for safe and long-life electrochemical storage cells.
