In combination with additive manufacturing, which facilitates great flexibility of the implant design, it is possible to selectively adjust the microstructure of the material in the process, thereby control the corrosion and fatigue behavior. In the present study, conventional hot-rolled (HR) pure iron is compared to pure iron manufactured by electron beam melting (EBM). The microstructure, the corrosion behavior and the fatigue properties were studied comprehensively. The investigated sample conditions showed significant differences in the microstructures that led to changes in corrosion and fatigue properties. The EBM iron showed significantly lower fatigue strength compared to the HR iron. These different fatigue responses were observed under purely mechanical loading as well as with superimposed corrosion influence and are summarized in a model that describes the underlying failure mechanisms.}}, author = {{Wackenrohr, Steffen and Torrent, Christof Johannes Jaime and Herbst, Sebastian and Nürnberger, Florian and Krooss, Philipp and Ebbert, Christoph and Voigt, Markus and Grundmeier, Guido and Niendorf, Thomas and Maier, Hans Jürgen}}, issn = {{2397-2106}}, journal = {{npj Materials Degradation}}, keywords = {{Materials Chemistry, Materials Science (miscellaneous), Chemistry (miscellaneous), Ceramics and Composites}}, number = {{1}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Corrosion fatigue behavior of electron beam melted iron in simulated body fluid}}}, doi = {{10.1038/s41529-022-00226-4}}, volume = {{6}}, year = {{2022}}, } @article{34214, abstract = {{This article presents the application and evaluation of a cantilever with integrated sensing and actuation as part of an atomic force microscope (AFM) with an adjustable probe direction, which is integrated into a nano measuring machine (NMM-1). The AFM, which is operated in closed-loop intermittent contact mode, is based on two rotational axes that enable the adjustment of the probe direction to cover a complete hemisphere. The axes greatly enlarge the metrology frame of the measuring system by materials with a comparatively high coefficient of thermal expansion, which ultimately limits the achievable measurement uncertainty of the measuring system. Thus, to reduce the thermal sensitivity of the system, the redesign of the rotational kinematics is mandatory. However, in this article, some preliminary investigations on the application of a self-sensing cantilever with an integrated micro heater for its stimulation will be presented. In previous investigations, a piezoelectric actuator has been applied to stimulate the cantilever. However, the removal of the piezoelectric actuator, which is enabled by the application of a cantilever with an integrated micro heater, promises an essential simplification of the sensor holder. Thus, in the future it might be possible to use materials with a low coefficient of thermal expansion, which are often difficult to machine and therefore only allow for rather simple geometries. Furthermore, because of the creepage of piezoelectric actuators, their removal from the metrology frame might lead to improved metrological characteristics. As will be shown, there are no significant differences between the two modes of actuation. Therefore, the redesigned rotational system will be based on the cantilever with integrated sensing and actuation.}}, author = {{Schaude, Janik and Hausotte, Tino}}, issn = {{2520-811X}}, journal = {{Nanomanufacturing and Metrology}}, keywords = {{Industrial and Manufacturing Engineering, Mechanical Engineering, Materials Science (miscellaneous)}}, number = {{2}}, pages = {{139--148}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Atomic Force Microscope with an Adjustable Probe Direction and Integrated Sensing and Actuation}}}, doi = {{10.1007/s41871-022-00143-9}}, volume = {{5}}, year = {{2022}}, } @article{40554, author = {{Rodríguez-Gómez, Alberto and Lepre, Enrico and Dorado, Fernando and Sanchez-Silva, Luz and Lopez Salas, Nieves and de la Osa, Ana Raquel}}, issn = {{2468-6069}}, journal = {{Materials Today Energy}}, keywords = {{Energy Engineering and Power Technology, Fuel Technology, Nuclear Energy and Engineering, Materials Science (miscellaneous), Renewable Energy, Sustainability and the Environment}}, publisher = {{Elsevier BV}}, title = {{{Efficient ethanol electro-reforming on bimetallic anodes supported on adenine-based noble carbons: hydrogen production and value-added chemicals}}}, doi = {{10.1016/j.mtener.2022.101231}}, volume = {{32}}, year = {{2022}}, } @article{40568, abstract = {{The search for metal-free and visible light-responsive materials for photocatalytic applications has attracted the interest of not only academics but also the industry in the last decades. Since graphitic carbon nitride (g-C3N4) was first reported as a metal-free photocatalyst, this has been widely investigated in different light-driven reactions. However, the high recombination rate, low electrical conductivity, and lack of photoresponse in most of the visible range have elicited the search for alternatives. In this regard, a broad family of carbon nitride (CxNy) materials was anticipated several decades ago. However, the attention of the researchers in these materials has just been awakened in the last years due to the recent success in the syntheses of some of these materials (i.e., C3N3, C2N, C3N, and C3N5, among others), together with theoretical simulations pointing at the excellent physico-chemical properties (i.e., crystalline structure and chemical morphology, electronic configuration and semiconducting nature, or high refractive index and hardness, among others) and optoelectronic applications of these materials. The performance of CxNy, beyond C3N4, has been barely evaluated in real applications, including energy conversion, storage, and adsorption technologies, and further work must be carried out, especially experimentally, in order to confirm the high expectations raised by simulations and theoretical calculations. Herein, we have summarized the scarce literature related to recent results reporting the synthetic routes, structures, and performance of these materials as photocatalysts. Moreover, the challenges and perspectives at the forefront of this field using CxNy materials are disclosed. We aim to stimulate the research of this new generation of CxNy-based photocatalysts, beyond C3N4, with improved photocatalytic efficiencies by harnessing the striking structural, electronic, and optical properties of this new family of materials.}}, author = {{Lopez Salas, Nieves and Albero, Josep}}, issn = {{2296-8016}}, journal = {{Frontiers in Materials}}, keywords = {{Materials Science (miscellaneous)}}, publisher = {{Frontiers Media SA}}, title = {{{CxNy: New Carbon Nitride Organic Photocatalysts}}}, doi = {{10.3389/fmats.2021.772200}}, volume = {{8}}, year = {{2021}}, } @article{46007, author = {{Zhai, Qingfeng and Pan, Ying and Dai, Liming}}, issn = {{2643-6728}}, journal = {{Accounts of Materials Research}}, keywords = {{Materials Chemistry, Polymers and Plastics, Materials Science (miscellaneous), Chemical Engineering (miscellaneous)}}, number = {{12}}, pages = {{1239--1250}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Carbon-Based Metal-Free Electrocatalysts: Past, Present, and Future}}}, doi = {{10.1021/accountsmr.1c00190}}, volume = {{2}}, year = {{2021}}, } @article{40381, abstract = {{Abstract The phenomenon of entanglement is the basis of quantum information and quantum communication processes.

The presented device allows to maximize the degree of spatial entanglement and generate the highly entangled four-dimensional Bell states. Furthermore, the use of the interferometer in different regimes leads to fast interference fringes in the coincidence probability with period of oscillations twice smaller than the pump wavelength.
