Iron oxide-based adsorbents showed potential to reach ultra-low phosphorus (P) concentrations to prevent eutrophication and recover P. High affinity, high capacity at low P concentrations (&lt;1 mg L<sup>−1</sup>), good stability, and reusability of the adsorbent are key factors for economic viability. In this study, nanoparticles of goethite...

Porous biodegradable Mg and its alloys are considered to have a great potential to serve as ideal bone substitutes. The recent progress in additive manufacturing (AM) has prompted its application to fabricate Mg scaffolds with geometrically ordered porous structures. Extrusion-based AM, followed by debinding and sintering, has been recently...

First, porous asphalt (PA) pavement possesses a lower strength and lifetime compared to typical dense-grade asphalt mixtures due to its large empty space structure. Second, PA pavements' fatigue life and durability are affected significantly by climate factors; the two most critical factors being aging conditions and moisture actions. Third,...

HIsarna reactor is characterized by a high raw materials versatility and is therefore attractive for processing secondary iron sources. Among the materials that can be recycled through HIsarna, zinc-bearing material has drawn a special attention. Based on the plant data, once dust-containing Zinc was injected into the main reactor, a final...

We performed advanced opto-electrical simulations on thin-film BaSi<sub>2</sub> solar cells. First, absorption spectra of BaSi<sub>2</sub>-pn homojunction solar cells on Si substrate were calculated based on flat and/or pyramidally-textured surfaces, wherein 20-nm-thick n<sup>+</sup>-BaSi<sub>2</sub> was the topmost electron transport layer....

During the production of steel, a dust waste stream is created that contains a significant amount of zinc which makes it difficult to treat and to recycle. Various furnaces have been developed that can deal with those dusts like rotary hearth furnaces and the DK process but none are fully optimal yet. HIsarna, a furnace in development by Tata...

The increasing availability of complex multivariate data yielded by sensor technologies permits qualitative and quantitative data analysis for material characterization. Multivariate data are hard to understand by visual inspection and intuition. Thus, data-driven models are required to derive study-specific insights from large datasets. In the...

Background. The past four decades, the problem of resistant bacteria has emerged. As a result of biofilm formation of (resistant) bacteria on the implant, more implant-associated infections (IAI) occurred. This has caused an increase in orthopaedic implant revisions, causing a high burden of disease. To overcome the rising problem of resistance,...
