Wind turbine blade fiberglass soaked in a 2 hour salt bath came back as nylon more than three times stronger and eight times stiffer than before
4+ hour, 38+ min ago (679+ words) The blade has been sitting in a landfill outside Casper, Wyoming, for the better part of a decade. It arrived well over 100 feet long, sawn into sections so it would fit on a semitrailer. Landfill managers describe the fiberglass as…...
Applied Sciences, Vol. 16, Pages 9095: Strain-Based Quantitative Inversion of Localized Corrosion Defects in Storage Tanks Using Finite Element-Driven Machine Learning
4+ hour, 21+ min ago (409+ words) Wall thinning caused by corrosion changes the circumferential strain response of storage tanks, but nonlinear coupling among structural parameters, loading conditions, strain characteristics, and defect geometry makes direct inversion difficult. This paper develops a strain-based, finite element (FE)-based machine…...
Ceramic road harvesters pulled out of a Chinese street after 2 years were crushed and sintered back into new discs, and the rebuilt ceramic came back close to the voltage of a factory fresh part
4+ hour, 38+ min ago (786+ words) A saw cut square in a city street, traffic cones around it, a steel housing sitting in the hole. Inside the housing is a stack of pale gray discs, each about the size of a coin. A gloved hand lifts…...
Applied Sciences, Vol. 16, Pages 9080: Numerical Evaluation of Proton-Exchange Membrane Fuel Cell Degradation in Real Driving Conditions and Accelerated Stress Tests
8+ hour, 45+ min ago (421+ words) Proton-exchange membrane fuel cell degradation is one of the factors that limit the deployment of this technology in the automotive market. Accelerated Stress Tests (ASTs) are the standard tool for assessing durability during design and development phases, thanks to their…...

Discover how the Customer Services ‘Connected Scanner’ approach of Siemens Healthineers seamlessly enhances the performance…...
A 12 month project in Laramie cooked the resin out of scrap turbine blade in vegetable oil and got back an oil that softens tired road asphalt, but the commercial agent it was measured against is vegetable oil too
16+ hour, 38+ min ago (784+ words) Old asphalt is not dry. That is the first thing to get wrong about it. A road binder starts out as a suspension, with hard sticky particles carried in a lighter oily fraction that keeps them apart. Sunlight and air…...
Why Adding Eco-Friendly PLA Can Silence Piezoelectric PVDF Polymers
12+ hour, 11+ min ago (56+ words) Piezoelectric polymers have long promised a future in which the flex of a shoe sole, the flutter of a breath, or the vibration of a bridge quietly generates its own electricity, powering sensors and wearables without a single battery swap....
Tiny Metal Cages Could Transform Food Industry Enzymes Into Reusable
14+ hour, 6+ min ago (715+ words) Enzymes are the quiet workhorses of the modern food industry, quietly cleaving sugars, clarifying juices, and softening doughs in plants around the world. Yet they have always carried an awkward industrial weakness: used once, they are typically discarded along with…...
Ultra-Tough Concrete Jacket Could Rescue Corroded Bridges, Simulation Study
18+ hour, 7+ min ago (55+ words) Reinforced concrete has carried the modern world on its shoulders, from cross-sea bridges and port terminals to offshore wind platforms, but the ocean is quietly eating away at its skeleton. Chloride-laden seawater penetrates even well-made concrete, triggering rust formation inside…...
Scientists Depolymerize Commercial Polymethacrylates at Lower Temperatures
18+ hour, 38+ min ago (652+ words) A new study published in Nature Chemistry reports a chemical strategy that allows commercial polymethacrylates, a widely used family of acrylic plastics, to be broken down back into their original monomers at substantially lower temperatures than previously required....
