Researchers Propose Methods for Additive Manufacturing Quality Control. Additive manufacturing offers an unprecedented level of design flexibility and expanded functionality, but the quality and process can drastically differ across production machines, according to Hui Yang, a professor of industrial engineering at Penn State. With applications in aerospace, health care and automotive industries with potential for mass customization, additive manufacturing needs quality management. To address this concern, Yang and a team of researchers from Penn State, University of Nebraska—Lincoln and the National Institute of Standards and Technology (NIST) proposed ...

Computers Help Researchers Find Materials to Turn Solar Power into Hydrogen. Using solar energy to inexpensively harvest hydrogen from water could help replace carbon-based fuel sources and shrink the world’s carbon footprint. However, finding materials that could boost hydrogen production so that it could compete economically with carbon-based fuels has been, as yet, an insurmountable challenge. In a study , a Penn State-led team of researchers report they have taken a step toward overcoming the challenge of inexpensive hydrogen production by using supercomputers to find materials that could help accelerate hydrogen separation when water is exposed to light, ...

The Top 3D Printing Applications in Sports. 3D printing technologies are becoming increasingly popular. This becomes particularly clear when taking a look at the all the industries that are now using additive manufacturing. These include not only those you would expect, like aerospace, construction and medicine, but also the sports industry. The use of 3D printing in sports is not limited to only a few, isolated sports – on the contrary, ranging from surfboards and golf clubs to sports and ski boots, there is something for almost every sports fan. However, additive manufacturing is most often used for the production of various types of protective equipment due ...

New Material Removes Air-Borne Droplets. Although plexiglass barriers are seemingly everywhere these days — between grocery store lanes, around restaurant tables and towering above office cubicles — they are an imperfect solution to blocking virus transmission. Instead of capturing virus-laden respiratory droplets and aerosols, plexiglass dividers merely deflect droplets, causing them to bounce away but remain in the air. To enhance the function of these protective barriers, Northwestern University researchers have developed a new transparent material that can capture droplets and aerosols, effectively removing them from air. The material is a clear, viscous ...

Paul Scherrer Institut (PSI) researchers have developed a new tomography method with which they can measure chemical properties inside catalyst materials in 3-D extremely precisely and faster than before. In a collaborative effort, scientists from two research divisions at PSI – the Photon Science Division and the Energy and Environment Division – together with researchers at ETH Zurich and the Swiss company Clariant AG, have now investigated in detail the ageing process of vanadium phosphorus oxides (VPOs), whic are widely used as catalysts in the chemical industry. In the course of their research, they also developed a new experimental method. The application ...

Researchers at Worcester Polytechnic Institute announced on Tuesday they have developed a form of concrete that will fix its own cracks. Using an enzyme found in red blood cells, they posit the new product is four times more durable than traditional concrete, and published their work in the journal Applied Materials Today. According to the research, the enzyme used in the material automatically reacts with atmospheric carbon dioxide to create calcium carbonate crystals, which mimic concrete in structure and strength, and can fill cracks before larger problems develop. The process can reportedly heal millimeter-scale cracks within 24 hours. To find out ...

Post-Consumer Aluminium Scrap Tops 20 Million Tonnes for the First Time. The International Aluminium Institute (IAI) has released new data revealing a record 20 million tonnes of post-consumer scrap intake in 2019. This avoids 300 million tonnes of greenhouse gas emissions as the recycled metal reduces demand for primary aluminium. This new high, published in the latest IAI Material Flow Model update, represents nearly 60% of total scrap intake as post-consumer continues to outstrip pre-consumer scrap levels. The post-consumer scrap intake came from three main sources – packaging, vehicles and building and construction. #News #Recycling #WasteManagement ...

Hexagonal boron nitride (h-BN) is the iron man of 2D materials, so resistant to cracking that it defies a century-old theoretical description engineers still use to measure toughness. “What we observed in this material is remarkable,” said Rice University‘s Jun Lou, co-corresponding author of a Nature paper published recently. “Nobody expected to see this in 2D materials. That’s why it’s so exciting.” Lou explains the significance of the discovery by comparing the fracture toughness of h-BN with that of its better-known cousin graphene.

Order Up! AI Finds the Right Material. Engineers are always looking for materials with very specific properties for their projects. Unfortunately, there are way too many options for researchers to simply guess-and-check until they find what they’re looking for. Even if they were to simulate materials, instead of testing them in the lab, it would take far too long to find a suitable material. Luckily, researchers have created algorithms using artificial intelligence that will find the right material for any project. In a recently published paper , a team of Carnegie Mellon University and University of Calgary researchers have improved on one of these algorithms, ...

Innovative Process that Removes Key Hurdle for Next-Generation Solar Cells is also a Lockbox for Greenhouse Gases. Perovskite solar cells have progressed in recent years with rapid increases in power conversion efficiency (from 3% in 2006 to 25.5% today), making them more competitive with silicon-based photovoltaic cells. However, a number of challenges remain before they can become a competitive commercial technology. Now a team at the NYU Tandon School of Engineering has developed a process to solve one of them, a bottleneck in a critical step involving p-type doping of organic hole-transporting materials within the photovoltaic cells. The research appears ...

Machine Learning Aids in Materials Design. A long-held goal by chemists across many industries, including energy, pharmaceuticals, energetics, food additives and organic semiconductors, is to imagine the chemical structure of a new molecule and be able to predict how it will function for a desired application. In practice, this vision is difficult, often requiring extensive laboratory work to synthesize, isolate, purify and characterize newly designed molecules to obtain the desired information. Recently, a team of Lawrence Livermore National Laboratory (LLNL) materials and computer scientists have brought this vision to fruition for energetic molecules by ...
