Upcycling of waste plastics into value-added chemicals and fuels represents a promising orientation toward a more sustainable chemical industry. We present a selective process for hydrocracking waste polyolefins into a spectrum of branched gasoline-range C<sub>5-12</sub> hydrocarbons, utilizing a cerium-promoted Pt/HY as a metal-acid...

Nowadays, an increasing share of photovoltaic (PV) systems makes use of module- or submodule-level power electronics (PE). Furthermore, PE is used in stand-alone devices powered by PV-storage solutions. One way to facilitate further implementation of PE in PV applications is to integrate PE components into crystalline silicon PV cells. Herein...

A wide amount of existing building materials and consumables contains formaldehyde (HCHO) that may be released as a gas even after installation. The produced gas may concentrate in housing and offices, leading to a long-term exposure of the occupants. Living in such an environment, even at low concentrations less than 0.5 ppm, may lead to...

Energy storage is vital for the energy transition, enabling reliable power grids based on intermittent renewables. Reversible solid oxide cell (rSOC) technology is promising for seasonal energy storage. The novel finding from this work is that optimised air recirculation for rSOC in endothermic electrolyser mode leads to efficiency being...

Cobalt oxidation is a relevant deactivation pathway of titania-supported cobalt catalysts used in Fischer-Tropsch synthesis (FTS). To work towards more stable catalysts, we studied the effect of the surface area of the titania support and noble metal promotion on cobalt oxidation under simulated high conversion conditions. Mössbauer...

Boron doped MoSi<sub>2</sub> particles have been envisioned as sacrificial particles for self-healing thermal barrier coatings (TBCs) but their oxidation behaviour is yet not well understood. In this work, oxidation of MoSi<sub>2</sub> based particle is studied in the temperature range of 1050–1200 °C. The oxidation proceeds from a transient...

Constructed wetlands (CWs) have been proven to effectively immobilize plastic particles. However, little is known about the differences in the impact of varying sized plastic particles on nitrous oxide (N<sub>2</sub>O) release, as well as the intervention mechanisms in CWs. Here, we built a lab-scale wetland model and introduced plastic...

The substitution of chromate-containing structural coating systems in aviation with alternatives complying with nowadays strict environmental, health and safety regulations remains a formidable challenge. This complexity is partly due to the absence of a standardized from-test-to-market methodology, including a performance comparison between...

Phosphorous not only needs to be removed to prevent eutrophication of wastewater effluent receiving surface water bodies, but it also has to be recovered as a scarce finite reserve. Phosphorus chemical precipitation as NH<sub>4</sub>MgPO<sub>4</sub>·6H<sub>2</sub>O, Ca<sub>3</sub>(PO<sub>4</sub>)<sub>2</sub>, or Fe<sub>3</sub>(PO<sub>4</sub>)...

Increasing the electrode thickness, thereby reducing the proportion of inactive cell components, is one way to achieve higher-energy-density lithium-ion batteries. This, however, results in higher electronic and ionic overpotentials and/or mechanical failure induced by binder migration. Here, we report ethanol-induced phase inversion as an...

Rapid sand filters (RSF) are an established and widely applied technology for the removal of dissolved iron (Fe<sup>2+</sup>) and ammonium (NH<sub>4</sub><sup>+</sup>) among other contaminants in groundwater treatment. Most often, biological NH<sub>4</sub><sup>+</sup>oxidation is spatially delayed and starts only upon complete Fe<sup>2+</sup>...

Anaerobic digestion (AD) is a biochemical process in which organic matter is converted into biogas in a series of biochemical reactions. The development of high-rate anaerobic reactors (HRAR) led to the breakthrough of full-scale applications of AD for the treatment of industrial wastewater. HRARs, such as the upflow anaerobic sludge blanket ...
