  An MIT team has engineered a composite made mostly from cellulose nanocrystals mixed with a bit of synthetic polymer. The organic crystals take up about 60 to 90 percent of the material — the highest fraction of CNCs achieved in a composite to date. The researchers found the cellulose-based composite is stronger and tougher than some types of bone, and harder than typical aluminum alloys. The material has a brick-and-mortar microstructure that resembles nacre, the hard inner shell lining of some molluscs. The Recipe for CNC-based Composite The team hit on a recipe for the CNC-based composite that they could fabricate using both 3D printing and conventional casting. They printed and cast the composite into penny-sized pieces of film that they used to test the material’s strength and hardness. They also machined the composite into the shape of a tooth to show that the material might one day be used to make cellulose-based dental implants — and for that matter, any plastic products — th

  📢Spreading the Word!📢 L M Wind Power reports it will produce zero waste blades by 2030! "LM Wind Power announced its pledge to produce zero waste blades by 2030 in order to reduce the carbon footprint of the company’s products. The commitment represents a step forward in the company’s sustainability journey after becoming what it says was the first carbon-neutral business in the wind industry back in 2018." "LM Wind Power will play a central role in supporting its customers to develop fully circular wind turbines that generate less waste during their production. In practice, LM Wind Power’s vision of zero waste blades means the company aims to send no manufacturing materials and packaging to landfill and incineration without energy recovery by 2030." "Waste from manufacturing represents one of the biggest challenges faced by many industries as they seek to reduce their carbon footprint. Nearly one-third of its operational carbon footprint comes from waste d

  DSM Engineering Materials has supported Samsung Electronics to deliver the first smartphone device to be made with Akulon® RePurposed. This high-performance polymer is produced by DSM from repurposing discarded fishing nets collected from the Indian Ocean. The new Galaxy S22 series smartphones and Tab S8 series tablets mark an important milestone in the sustainability of smartphone devices and underline DSM’s commitment to enabling a circular economy through recycled-based innovation. Launched in 2018, Akulon® RePurposed is made by partnering with the local community along India’s coastline to collect and retrieve abandoned fishing nets. These are then processed into the exceptional polymer, containing a minimum of 80% recycled polyamide 6. Akulon® RePurposed for New Galaxy Series Working with Samsung Electronics, DSM tailored Akulon® RePurposed to meet the specific high-performance requirements of the new Galaxy S22 series and Galaxy Tab S8 series. As such, the material is incorpora

  📢It's time for our segment Endless Possibilities!📢 A carbon fiber golf driver? T@aylorMade Golf Company builds on its history of groundbreaking innovation with the introduction of the Stealth™ Plus, Stealth, and Stealth HD Carbonwood™ Drivers! Titanium has been the cornerstone of driver technology for the last 20 years, but even at the beginning of the Titanium driver era, TaylorMade engineers knew that every material had its limit. The future of driver performance begins with the one-of-one 60X Carbon Twist Face – comprised of 60 layers of carbon sheets strategically arranged to optimize energy transfer. But why carbon? The goal of any new technology is to create a measurable performance improvement for TaylorMade customers. The 60 layers of carbon fiber in Stealth help do exactly that by providing more speed. The red carbon face – yes, the face is red – delivers a higher COR and more precise face geometry through a lighter, but larger face. TaylorMade engineers took advantage

  #science 📢Time to Get Technical...📢 Let's learn more about the dry-jet wet spinning process of producing aramid fibers! Aramid fiber is a generic term for a class of synthetic organic fibers called aromatic polyamide fibers. The U.S. Federal Trade Commission gives a good definition of an aramid fiber as “a manufactured fiber in which the fiber-forming substance is a long-chain synthetic polyamide in which at least 85% of the amide linkages are attached directly to two aromatic rings.” Well-known commercial names of aramid fibers include Kevlar and Nomex (DuPont) and Twaron (Teijin Aramid). The basic chemical structure of aramid fibers consists of oriented para-substituted aromatic units, which makes them rigid rodlike polymers. The rigid rodlike structure results in a high glass transition temperature and poor solubility, which makes the fabrication of these polymers, by conventional drawing techniques, difficult. Instead, they are spun from liquid crystalline polymer solution
