Hardmetal and tooling specialist Sandvik highlighted the company’s digital activities during an event at its headquarters in May 2019. According to Petra Sundström, head of digital business said that digital technologies we see today, such as artificial intelligence and the Internet of Things, work as a glue that connects several different areas. ‘What I mean is that before we basically could produce hardware – unique and highly skilled products – and then we could leave them with the customers,’ she said.

Researchers have demonstrated that vehicle armor based on composite metal foam (CMF) can stop ball and armor-piercing .50 caliber rounds just as well as conventional steel armor, even though it weighs less than half as much. This finding means that vehicle designers will now be able to develop lighter military vehicles without sacrificing safety, or can improve protection without making vehicles heavier. CMF is a foam that consists of hollow, metallic spheres – made of materials such as stainless steel or titanium – embedded in a metallic matrix made of steel, titanium, aluminum or other metallic alloys. In this study, the researchers used steel-steel CMF, meaning that both the spheres and the matrix were made of steel. For the study, the r.

Like fishermen, bioengineers at Rice University are angling for their daily catch. But their bait, biomolecules in a hydrogel scaffold, lures microscopic stem cells instead of fish. These, they say, will seed the growth of new tissue to heal wounds. The team, led by Brown School of Engineering bioengineer Antonios Mikos and graduate student Jason Guo, has developed modular, injectable hydrogels enhanced by bioactive molecules anchored to the chemical crosslinkers that give the gels structure. Until now, hydrogels for healing have been biologically inert, and required growth factors and other biocompatible molecules to be

Additive manufacturing (AM) company 3D Systems says that two racing car companies, Rodin Cars and Stewart-Haas Racing have made use of the company’s plastic and metal 3D printing technology to help improve speed and performance in their cars. Rodin Cars, based in New Zealand, uses 3D Systems’ direct metal printing (DMP), selective laser sintering (SLS) and stereolithography (SLA) technologies to develop open-wheel cars for racetracks. ‘The extreme conditions of track racing leave no room for error,’ said David Dicker, founder of Rodin Cars.

3D printing company EOS is running a webinar on 26 June 2019 covering how to gain production qualification for additive manufacturing (AM). The webinar, run by EOS application development consultant Michael Kowal is entitled ‘No Risk and Lots of Fun: AM Production Qualification’ to demonstrate how production qualification works for industrial 3D printing using examples from the medical sector. The webinar will also cover how to validate AM technology for production, the difference between AM and other production qualifications, examples of best practice in the medical sector and different validation methods and insights into the use of lattice structures and the reusability of metal materials, EOS says.

Strain-tolerant, triangular, monolayer crystals of tungsten disulfide were grown on silica substrates patterned with donut-shaped pillars, as shown in scanning electron microscope (bottom) and atomic force microscope (middle) images. The curvature of the pillars induced strain in the overlying crystals that locally altered their optoelectronic properties, as shown in the bright regions of photoluminescence (top). Image: Christopher Rouleau/Oak Ridge National Laboratory, US Dept. of Energy. A team led by scientists at the US Department of Energy's Oak Ridge National Laboratory (ORNL) has explored how atomically thin two-dimensional (2D) crystals can grow over three-dimensional (3D) objects, and how the curvature of those objects can stretch

Smart glass is gaining popularity as an energy-efficiency product for buildings, cars and airplanes. Photo: Steven Marquez/Colorado State University. ‘Smart glass’, an energy-efficiency product found in newer windows of cars, buildings and airplanes, slowly changes between transparent and tinted at the flick of a switch. ‘Slowly’ is the operative word, though; typical smart glass takes several minutes to reach its darkened state, and cycling repeatedly between light and dark also tends to degrade the tinting quality over time. Now, chemists at Colorado State University have devised a potentially major improvement to both the speed and durability of smart glass by providing a better understanding of how the glass works at the nanoscale. As t.

Sumika Polymer Compounds Europe, a subsidiary of Sumitomo Chemical, says that it has agreed to acquire Turkish company Emas. Ema, which was founded in 1978, is reportedly a key player in the Turkish compounding market. Sumika manufactures polypropylene (PP) short glass fiber under the Thermofil brand. With this acquisition, it will have three new compounding sites in a region of strong economic development, the company says, and can extend its sales of Thermofil into Turkey. Sumika also reports that it will invest in the production equipment of its future sites in Turkey. This story uses material from Sumika , with editorial changes made by Materials Today.

"We were able to demonstrate a hitherto undiscovered interaction. It occurs between two thin magnetic layers separated by a non-magnetic layer.". Kyujoon Lee, Johannes Gutenberg University Mainz. The more we stream videos, download audiobooks and store photos on our mobile devices, the more storage capacity we will need, and so researchers are working to develop new data storage options. One possibility is racetrack memory, where the data is stored in the form of oppositely magnetized areas, or domains, on nanowires. A research team from Johannes Gutenberg University (JGU) Mainz in Germany, together with colleagues from Eindhoven University of Technology in the Netherlands and from Daegu Gyeongbuk Institute of Science and Technology and Sogan.

VTT Technical Research Centre of Finland says that it is researching chemical recycling of plastics based on pyrolysis, which can turn nearly all plastics and their mixtures into oil. According to the organization, while mechanical recycling suits most plastic bottles, bags and wraps, 40–60% of separately collected plastic waste in Finland does not qualify for this type of recycling and ends up incinerated. ‘By chemical recycling, however, plastics and their mixtures can be broken down into separate raw materials, whose quality is equal to that of respective virgin materials,’ said Anja Oasmaa, senior principal scientist at VTT. According to VTT, chemical recycling offers an ecologically sound alternative to incineration and possibly to mec.
