Nearly three years after the official launch of the post-2015 agenda, which plots the path for a better world by 2030, people are still grappling with how to make the ambitious Sustainable Development…

1. Introduction The Carbon Dioxide Utilisation Summits are held twice per year, alternating between being hosted in a European location and in North America. They are organised by Active Communications International (ACI), Inc. This two-day event was held in Reykjavik, Iceland, on 18th and 19th October 2017. The main aim of this Summit series is…

An optimal platinum alloy for precision casting was developed by taking 25 possible alloying elements into consideration. In order to rank these elements an equation was designed. The ranking allowed five promising alloy compositions to be identified. From these five alloys arc melted buttons were produced and tested for homogeneity and hardness to ensure their suitability as jewellery alloys. A pyrometer was used to measure solidus temperatures. In a second iteration, the five alloys were further improved and the most promising alloys were cast and compared to a commonly used jewellery alloy: platinum-copper-gallium (PtCuGa). The comparison was based on the melting interval and on microstructural investigations, carried out by scanning electron and optical microscopy, while mechanical properties were determined by tensile testing. Additionally, optical properties such as reflectivity and colour were investigated. After the second iteration two very promising compositions were identified: PtCuFeMnCr and PtCuFePdVY.

Infant formula is perhaps one of the most highly regulated foodstuffs in the world, so checking the exact composition is a rigorous affair. ISO is developing a series of standards for verifying many of…

Industrial processes contribute significantly to global carbon dioxide emissions, with iron and steel manufacturing alone responsible for 6% of the total figure. The STEPWISE project, funded through the European Horizon 2020 (H2020) Low Carbon Energy (LCE) programme under grant agreement number 640769, is looking at reducing CO₂ emissions in the iron and steel making industries. At the heart of this project is the ECN technology called sorption-enhanced water-gas shift (SEWGS), which is a solid sorption technology for CO₂ capture from fuel gases such as blast furnace gas (BFG). This technology combines water-gas shift (WGS) in the WGS section with CO₂/H₂ separation steps in the SEWGS section. Scaling up of the SEWGS technology for CO₂ capture from BFG and demonstrating it in an industrially relevant environment are the key objectives of the STEPWISE project, which are achieved by international collaboration between the project partners towards design, construction and operation of a pilot plant at Swerea Mefos, Luleå, Sweden, next to the SSAB steel manufacturing site.
