Forget glue, screws, heat or other traditional bonding methods. A Cornell University-led collaboration has developed a 3D printing technique that creates cellular metallic materials by smashing together powder particles at supersonic speed.
This form of technology, known as "cold spray,"...
Pressure treating—which involves putting lumber inside a pressurized watertight tank and forcing chemicals into the boards—has been used for more than a century to help stave off the fungus that causes wood rot in wet environments.
Now researchers at the...
Many natural products and drugs feature a so-called dicarbonyl motif— in certain cases, however, their preparation poses a challenge to organic chemists. In their most recent work, Nuno Maulide and his coworkers from the University of Vienna present a...
Methanol is a versatile and efficient chemical used as fuel in the production of countless products. Carbon dioxide (CO2), on the other hand, is a greenhouse gas that is the unwanted byproduct of many industrial processes.
Converting CO2 to methanol...
This reusable, multi-layered and microfluidic device incorporates a porous growth substrate, with a physiological fluid flow, and the passive filtration of the capillaries around the end of a kidney, called the glomerulus, where waste is filtered from blood. Credit:...
Materials are widely used to help heal wounds: Collagen sponges help treat burns and pressure sores, and scaffold-like implants are used to repair bones. However, the process of tissue repair changes over time, so scientists are developing biomaterials that...
A joint research group including Ryo Yoshida (Professor and Director of the Data Science Center for Creative Design and Manufacturing at the Institute of Statistical Mathematics , Research Organization of Information and Systems), Junko Morikawa (Professor at the School...
Rutgers engineers have created a highly effective way to paint complex 3-D-printed objects, such as lightweight frames for aircraft and biomedical stents, that could save manufacturers time and money and provide new opportunities to create "smart skins" for printed...
Some materials are like people. Let them relax in the sun for a little while and they perform a lot better.
A collaboration led by Rice University and Los Alamos National Laboratory found that to be the case with a...
In a September 2020 essay in Nature Energy, three scientists posed several "grand challenges"—one of which was to find suitable materials for thermal energy storage devices that could be used in concert with solar energy systems. Fortuitously, Mingda Li—the Norman...
Antibiotic-resistant bacteria are an increasing health threat, making new antibiotics essential. German researchers have recently had a breakthrough: they discovered lugdunin in the human nose—a new kind of cyclic peptide that comes from the bacterium Staphylococcus lugdunensis and has...
