Nexam Chemical has been selected as a key partner in the “TAPE Extreme” project, financed by Innovate UK, targeting development of advanced temperature resistant composites for the UK aerospace sector. Nexam Chemical adds competencies within chemistry, polymers and resins to the consortium, and has been awarded a £100K grant with the objective of developing novel materials that can replace metals in jet engines. Aim to Replace Metals in Jet Engines Leading to Lighter Components: Nexam Chemical St. Andrews has, together with partners from the whole value chain, been selected as a key partner in the project, dubbed “Advanced Thermoformable Cross-linking Resin Unidirectional Tapes”, which consists of a consortium of commercial players within composites and aerospace, in partnership with the University of Sheffield. Nexam Chemical’s part of the grant is £100K, which will primarily be used for R&D activities. The project’s main objective is to drive replacement of metals like titanium a

Today's KNOWLEDGE Share Why do thick parts need more packing than thin ones ? Packing changes the parts size/volume/mass, but not the final density. Whatever is already solid at the end of fill (frozen skin) does not need any packing (shrinkage has already occurred !). So, as the picture shows (in a slightly exaggerated way) in a thin part/section one only has to pack a tiny fraction of the total volume, whereas in a thick part/section, most of the volume will need to be packed, to compensate for the shrinkage. Since thick parts are easy to fill and need more packing, it is not unusual to use a packing pressure much higher than the filling pressure. Something that might not fit the default values proposed by simulation... Always think twice before accepting a default value. Source:Vito leo Follow: http://polymerguru.blogspot.com

Today's KNOWLEDGE Share The production and use of hydrogen does not consume any water. The water that we use to produce hydrogen via water electrolysis comes back when we use the hydrogen to produce electricity and/or heat. To produce 1 kg hydrogen, we need 9 litres very clean water. But when we use 1 kg hydrogen to produce electricity and/or heat, you get 9 litres of very clean water back.   So, when using hydrogen, we produce very clean water. As an example, when we drive 100 km in a fuel cell car, we use 1 kg hydrogen and produce 9 litres very clean water. Enough drinking water for 3 days for 1 person   Hydrogen produced from water is therefore a circular energy carrier, that do not use water. In fact, with hydrogen, you do not only transport energy but also clean water over the world.   Read more about #hydrogenproduction by electrolysis of water in the book ‘Green Energy for All, how hydrogen and electricity carry our future’.  https://lnkd.in/eJ9Xxk-n Source:Ad van Wijk Foll

Offering a truly bespoke build for each owner, the world’s first online bicycle configurator offers the exact colours and materials available on Aston Martin’s ultra-luxury, high performance sportscars. Aston Martin and British titanium bicycle leader J.Laverack have united to create a road bicycle without equal; the J.Laverack Aston Martin .1R. Developed with input from high-performance automotive designers, the .1R is the most bespoke, most advanced and most engineered bicycle ever created featuring a number of world firsts. Synergising the shared values of the two high performance British brands, Aston Martin and J.Laverack have applied truly innovative design and engineering processes to produce a fully integrated ‘visually boltless’ design that possesses an aesthetic purity and obsession to detail beyond compare. The J.Laverack Aston Martin .1R uses a flawless fusion of parametrically designed, 3D printed titanium lugs and sculpted carbon fibre tubes. This ensures a frame that not

A group of DTU researchers have therefore investigated new possibilities for recycling the plastic waste in collaboration with Roskilde University and a number of industry partners. Their research project RePlastic has shown that a valuable oil can be produced from otherwise useless plastic waste through pyrolysis. Assessed the Potential of Several Plastic Materials in the Waste: “I’m surprised at the great potential of pyrolysis technology for the most impure and mixed plastic fractions. This process can handle the plastic we have no other uses for. This enables us to bring end-of-life plastic back into the cycle and make it useful again,” says Anders Egede Daugaard, associate professor at DTU Chemical Engineering and head of the RePlastic project. To fully understand Anders Egede Daugaard’s enthusiasm, you need to understand the challenges of recycling and sorting plastic waste into different categories and fractions. The current number of different plastic types with different prope

Today's KNOWLEDGE Share Chinese start-up unveils world's first gaseous-hydrogen truck with 1,000km range Guangzhou-based Hybot says its fuel cell is 20% more efficient than rivals’ tech, requiring 8kg of H2 per 100km Guangzhou-based Hybot says its H49 vehicle will only require 8kg of #H2  per 100km when travelling at high speed with a full cargo load of 49 tonnes — partly due its low weight of less than nine tonnes, and partly due to a fuel cell that it claims is 20% more efficient than rivals’ technology. Hydrogen fuel-cell trucks normally have a fuel consumption of 9-9.2kg per 100km — 12.5-15% higher than the H49 — according to the International Council on Clean Transportation. Germany’s Daimler has also unveiled a truck that can travel further than 1,000km on a single tank, but that runs on cryogenic liquid hydrogen — which contains 50% more energy by volume than gaseous hydrogen at 700 bar, and is not dispensed at any public H2 filling station. The H49 also has a secondary

Today's KNOWLEDGE Share Otto Wallach-Nobel prize 1910 In 1910 Otto Wallach (1847 to 1931) was awarded the Nobel Prize for Chemistry for his achievements in the fields of organic chemistry and the chemical industry for his pioneering work in the area of alicyclic compounds. Following studies in chemistry and natural sciences at the University of Göttingen he completed his Doctorate in 1869. After many years at the University of Bonn he was appointed professor of chemistry at the University of Göttingen in 1889, a post he held until his retirement in 1915. Wallach remained an active researcher until 1927. Wallach’s main contribution was in laying the groundwork for the identification of the terpenes – a group of natural and synthetic hydrocarbons – and in determining the characteristics of camphor. camphor is a natural substance with a sharp aromatic smell, used in medicine for its sterilizing and anesthetic capabilities, and in the cosmetics industry for its pleasant aroma. Wallach’
