ICFO researchers report on a new method to obtain high color purity 3D objects with the use of a new class of nanoparticles.
The science behind sticky gecko's feet lets gecko adhesion materials pick up about anything. But cost-effective mass production of the materials was out of reach until now. A new method of making them could usher the spread of gecko-inspired grabbers to assembly lines and homes.
Spoiling foods, souring wine and worsening wounds have a common culprit -- a process called oxidation. Although the ill effects of these chemical reactions can be curtailed by antioxidants, creating a sturdy platform capable of providing prolonged antioxidant activity is an ongoing challenge.
Researchers at the universities of Jyvaskyla and Xiamen discovered a novel way to make functional macroscopic crystalline materials out of nanometer-size 34-atom silver-gold intermetallic clusters. The cluster material has a highly anisotropic electrical conductivity, being a semiconductor in one direction and an electrical insulator in other directions. The research was published in Nature Communications on May 6, 2020.
Modern society relies on polymers, such as polypropylene or polyethylene plastic, for a wide range of applications, from food containers to automobile parts to medical devices. However, like people, polymers age, and when they do, the materials become prone to cracking or breaking. Now, researchers reporting in ACS Central Science have developed a method to visualize variations in polymers that arise with age.
EPFL chemists have developed sponges to capture various target substances, like gold, mercury and lead, dissolved in solution. The sponges are actually porous crystals called metal organic frameworks, and now one exists for capturing toxic hexavalent chromium from water.
Researchers have developed a material that is up to 40 times faster in desalinating small batches of water than other materials available today.
Rice University researchers have integrated high-efficiency solar cells and electrode catalysts into an efficient, low-cost device that splits water to produce hydrogen fuel.
Scientists have discovered how the materials used in medical implants like artificial joints can be adapted to control the immune response to them and reduce the risk of rejection.
From snowflakes to quartz, nature's crystalline structures form with a reliable, systemic symmetry. Researchers at Drexel University, who study the formation of crystalline materials, have shown that it's now possible to control how crystals grow - including interrupting the symmetrical growth of flat crystals and inducing them to form hollow crystal spheres. The discovery is part of a broader design effort focused on the encapsulation of medicine for targeted drug treatments.
