Li–S batteries hold great promise as the upcoming post-lithium-ion batteries owing to their notably high theoretical specific energy density of 2600 W h kg−1, nearly five-fold larger than that of current lithium-ion batteries. However, one of their major technical problems is found in the shuttling of soluble polysulfides between the electrodes, resulting in rapid capacity fading and poor cycling stability. This review spotlights the foremost findings and the recent progress in enhancing the electrochemical performance of Li–S batteries by using nanoscaled metal compounds and metals. Based on an overview of reported functional metal-based materials and their specific employment in certain parts of Li–S batteries, the underlying mechanisms of enhanced adsorption and improved reaction kinetics are critically discussed involving both experimental and computational research findings. Thus, material design principles and possible interdisciplinary research approaches providing the chance to jointly advance with related fields such as electrocatalysis are identified. Particularly, we elucidate additives, sulfur hosts, current collectors and functional interlayers/hybrid separators containing metal oxides, hydroxides and sulfides as well as metal–organic frameworks, bare metal and further metal nitrides, metal carbides and MXenes. Throughout this review article, we emphasize the close relationship between the intrinsic properties of metal-based nanostructured materials, the (electro)chemical interaction with lithium (poly)sulfides and the subsequent effect on the battery performance. Concluding the review, prospects for the future development of practical Li–S batteries with metal-based nanomaterials are discussed.}}, author = {{Balach, Juan and Linnemann, Julia and Jaumann, Tony and Giebeler, Lars}}, issn = {{2050-7488}}, journal = {{Journal of Materials Chemistry A}}, keywords = {{lithium-sulfur battery}}, number = {{46}}, pages = {{23127--23168}}, publisher = {{Royal Society of Chemistry (RSC)}}, title = {{{Metal-based nanostructured materials for advanced lithium–sulfur batteries}}}, doi = {{10.1039/c8ta07220e}}, volume = {{6}}, year = {{2018}}, } @article{62809, abstract = {{Superhierarchically rough films are rapidly synthesised on metal substrates via electrochemically triggered self-assembly of meso/macroporous-structured metal-organic framework (MOF) crystals.

Such omniphobic surfaces are highly interesting for several applications such as anti-fouling, anti-icing, and dropwise condensation, and become easily scalable with the presented bottom-up fabrication approach. As investigated by environmental scanning electron microscopy (ESEM), the presented perfluorinated oil-infused Cu-BTC coating constitutes of a flat liquid-covered surface with protruding edges of octahedral superstructured MOF crystals. Water and non-polar diiodomethane droplets form considerably high contact angles and even low-surface-tension fluids, e.g. acetone, form droplets on the infused coating.

In an ab initio context, it may be calculated within many-body perturbation theory or time-dependent density-functional theory, but the quantitative accuracy is currently limited by the available functionals for exchange and correlation in dynamically evolving systems. To circumvent this limitation, the spin susceptibility is here alternatively formulated as the solution of an initial-value problem. In this way, the challenge of accurately describing exchange and correlation in many-electron systems is shifted to the stationary initial state, which is much better understood. The proposed scheme further requires the choice of an auxiliary basis set, which determines the speed of convergence but always allows systematic convergence in practical implementations.}}, author = {{Schindlmayr, Arno}}, issn = {{1687-9139}}, journal = {{Advances in Mathematical Physics}}, publisher = {{Hindawi}}, title = {{{Exact formulation of the transverse dynamic spin susceptibility as an initial-value problem}}}, doi = {{10.1155/2018/3732892}}, volume = {{2018}}, year = {{2018}}, } @inproceedings{15952, abstract = {{Arbitrary sampling rate conversion has already received considerable attention in the past, but still lacks an equivalent representation of the effective time-dilation process in the block frequency domain. Good sampling rate converters in the time domain have been known, for instance, in terms of time-varying 'Sinc' or fixed 'Farrow' polynomial filters. The former can deliver nearly exact conversion at high complexity, while the latter has pronounced computational efficiency with limited accuracy. Only recently, it was shown that a composite 'polyphase Farrow' form with high resampling precision can be implemented with quasi-fixed filters that operate at the input sampling rate. We therefore propose to capitalize from that fixed-filter architecture in that we translate the polyphase-Farrow filters into an equivalent FFT-based overlap-save form. Experimental evaluation and comparison with other state-of-the art frequency-domain approaches then proves currently the best price-performance ratio of the proposed algorithm. It is thus an ideal candidate for the new framework of acoustic sensor networks that critically rests upon fast and accurate alignment of autonomous sampling processes.}}, author = {{Schmalenstroeer, Joerg and Chinaev, Aleksej and Enzner, Gerald}}, booktitle = {{Speech Communication; 13th ITG-Symposium}}, issn = {{null}}, pages = {{1--5}}, title = {{{Fast and Accurate Audio Resampling for Acoustic Sensor Networks by Polyphase-Farrow Filters with FFT Realization}}}, year = {{2018}}, } @inproceedings{24926, author = {{Mertens, Ulrich J. and Bergmann, Kirsten and Tolksdorf, Nils Frederik and Rohlfing, Katharina J.}}, location = {{Cape Town, South Africa}}, title = {{{Can the reduction of an iconic gesture aid long-term learning?
