Researchers at Penn State developed seven new high-entropy oxide ceramics by controlling oxygen levels during synthesis, stabilizing metals like iron and manganese in the desired structure, with potential applications in energy, electronics, and coatings.
EPFL scientists developed a novel 3D printing method using hydrogels as templates to produce ultra-dense, strong metals and ceramics, which are significantly more durable and less prone to warping than traditional methods, with potential applications in energy, sensors, and biomedicine.
A Thai ceramic artist, Trevor Foster, discovered a live frog trapped in his mold and quickly rescued it, leading to a memorable encounter and inspiring a new ceramic series.
Researchers at Duke University have developed a computational method called Disordered Enthalpy-Entropy Descriptor (DEED) to rapidly discover new ceramics that can withstand extreme heat and harsh environments, potentially revolutionizing electronics and other industries. The method has already predicted 900 new high-performance materials, with 17 successfully synthesized in the lab. These ceramics, made from transition metals carbonitrides or borides, could be used in a variety of applications, including wear-resistant coatings and thermoelectrics. The findings, which could lead to commercial production of these materials, were published in the journal Nature.
Scientists from the University of California San Diego have developed a method to make ceramics tougher and more resistant to cracking. By using a mix of metal atoms with a higher number of valence electrons, they have created high-entropy carbides that can withstand higher levels of force and stress. These ceramics exhibit a more ductile behavior, similar to metals, and can deform and stretch instead of breaking easily. The discovery opens up possibilities for applications in aerospace components, protective coatings, and extreme environments. Scaling up production for commercial use is the next challenge.
Apple is reportedly exploring new materials for future iPhone models beyond the iPhone 15, including titanium, ceramics, and plastics, to make them more resistant to drops, scuffs, and contamination. The iPhone 15 is expected to have Ceramic Shield glass front and back, with the side rail made of aluminum on the basic model and stainless steel on the iPhone 15 Pro and iPhone 15 Pro Max. It is unclear when Apple will officially incorporate these new materials into its products.
Apple is reportedly exploring new materials for future iPhone models beyond the iPhone 15, including titanium and ceramics, to make them more resistant to drops, scuffs, and contamination. The company is also considering using plastics in combination with glass and metal to strike a balance between looking good and being tough. The next expected generation of iPhones, the iPhone 15, is expected to have Ceramic Shield glass front and back, with the side rail made of aluminum on the basic model and stainless steel on the iPhone 15 Pro and iPhone 15 Pro Max.
Scientists at Jiangnan University in China have developed a new 3D printing technique for ceramics that allows them to be printed without support structures. This method enables the creation of previously impossible shapes and angles, making it easier to design and manufacture certain ceramic parts commonly used in electronics, mechanical engineering, and aerospace due to their structural integrity and resistance to wear and high temperatures.
Chinese scientists from Jiangnan University have developed a cutting-edge technique for 3D ceramic printing in the air, allowing for the creation of complex engineering parts without the need for support structures. The team created a new printing paste and improved curing technique to boost printing efficiency, overcoming the challenges posed by ceramics' brittleness and hardness.
