… thanks to new microscope. A team of scientists from the Department of Energy’s Ames National Laboratory developed a new characterization tool that allowed them to gain unique insight into a possible alternative material for solar cells. Under the leadership of Jigang Wang, senior scientist from Ames Lab, the team developed a microscope that uses terahertz waves to collect data on material samples. The team then used their microscope to explore Methylammonium Lead Iodide (MAPbI3) perovskite, a material that could…
A technique that transforms the metals’ microscopic structure may enable energy-efficient 3D printing of blades for gas turbines or jet engines. A new MIT-developed heat treatment transforms the microscopic structure of 3D-printed metals, making the materials stronger and more resilient in extreme thermal environments. The technique could make it possible to 3D print high-performance blades and vanes for power-generating gas turbines and jet engines, which would enable new designs with improved fuel consumption and energy efficiency. Today’s gas turbine blades…

The University of Bayreuth, together with two Australian partner universities, the University of Melbourne and Monash University, is establishing a new International Research Training Group (IRTG) in the field of semiconductor research. The college will start in spring 2023 and will be funded by the German Research Foundation (DFG) with more than six million euros for an initial period of five years. Outstanding young talents from the fields of physics,…
A flipping action in a porous material facilitates the passage of normal water to separate it out from heavy water. A research group led by Susumu Kitagawa of Kyoto University’s Institute for Cell-Material Sciences (iCeMS), Japan and Cheng Gu of South China University of Technology, China have made a material that can effectively separate heavy water from normal water at room temperature. Until now, this process has been very difficult and energy intensive. The findings have implications for industrial –…
Direct visualization of metal atoms during shear deformation has applications from batteries to lightweight vehicles. How can studying metals manufacturing lead to longer-lasting batteries and lighter vehicles? It all comes down to physics. Researchers at Pacific Northwest National Laboratory (PNNL) are investigating the effects of physical forces on metals by taking a direct look at atomic-level changes in metals undergoing shear deformation. The forces applied during shear deformation to change a metal’s shape also rearrange its atoms, but not in…
… help us breathe cleaner air. Although much of the discourse on reducing vehicle emissions centres on electric vehicles (EV), their sales remain low – with EV vehicles accounting for a mere 1% of car purchases in Japan in 2021. Meanwhile, the European Union is expected to pass stricter emission standards in the near future. This makes improving the performance and functionality of exhaust gas purification catalysts in petrol or diesel-powered vehicles a critical component in the push towards carbon…
Floppy or not: Given a 3D piece of origami, can you flatten it without damaging it? Just by looking at the design, the answer is hard to predict, because each and every fold in the design has to be compatible with flattening. This is an example of a combinatorial problem. New research led by the UvA Institute of Physics and research institute AMOLF has demonstrated that machine learning algorithms can accurately and efficiently answer these kinds of questions. This is…
Quantum materials enable next-generation photonics and mobile networks in the terahertz regime. Terahertz light, radiation in the far-infrared part of the emission spectrum, is currently not fully exploited in technology, although it shows great potential for many applications in sensing, homeland security screening, and future (sixth generation) mobile networks. Indeed, this radiation is harmless due to its small photon energy, but it can penetrate many materials (such as skin, packaging, etc.). In the last decade, a number of research groups…
Researchers hope designers can apply techniques from origami to medical devices, architecture, robotics and aerospace. Springs, squeegees and soda straws function with a common property — they are rigid in one direction and flexible in another. Structures like these, with properties that vary across dimensions, have played critical roles in human technology from the longbow to the booster rocket. Now, researchers have drawn inspiration from the art of origami to create programmable surfaces that allow engineers to alter physical properties…
Engineering researchers have developed a new self-healing composite that allows structures to repair themselves in place, without having to be removed from service. This latest technology resolves two longstanding challenges for self-healing materials, and can significantly extend the lifespan of structural components such as wind-turbine blades and aircraft wings. “Researchers have developed a variety of self-healing materials, but previous strategies for self-healing composites have faced two practical challenges,” says Jason Patrick, corresponding author of the research paper and an assistant…
It is cheaper its analogues, easier to manufacture and to modify. A new type of material for one of the solar cells was proposed by specialists of the Ural Federal University (UrFU) and the Institute of Organic Synthesis of the Ural Branch of the Russian Academy of Sciences together with their colleagues. The compounds found will significantly reduce the cost of solar cell production. The article was published in the New Journal of Chemistry. Perovskite solar cells (PSCs) are a…
Anisoprint arrived at Jacobs University Bremen. Starting in September 2022, 3D printing solution provider Anisoprint deployed their Research and Development Team at Jacobs University Bremen.

Fostering research and development of composites manufacturing with Continuous Fiber Coextrusion (CFC) technology, and establishing a research environment for 3D printing technologies on the university campus in Bremen, Germany. Following the announcement of the cooperation between Anisoprint and Jacobs University, the startup team moved their R&D operations to Bremen…
… could enable circular home furnishings and building materials. Plastics used in home furnishings and constructions materials could be replaced with a new kind of wood-based degradable plastic with semi-structural strength. Unlike thermoplastic, the material can be broken down without harm to the environment, researchers in Sweden have reported. One of the goals of renewable wood composite development is to make materials strong enough to replace fossil-based materials used in home construction and furnishing, such as bathroom cabinets, doors, wall-boards…
A research team, affiliated with UNIST has succeeded in achieving a power conversion efficiency (PEC) of 23.50% in a perovskite-silicon tandem solar cell built with a special textured anti-reflective coating (ARC) polymeric film. According to the research team, the PCE of the device with the ARC film was sustained for 120 hours, maintaining 91% of its initial value. This breakthrough has been led by Professor Kyoung Jin Choi and his research team in the Department of Materials Science and Engineering at UNIST, in collaboration…
Scientists have developed fluorophores that are 2.4 to 20 times more intense than analogues. Scientists have developed, synthesized, and studied a series of new fluorophores, a luminous chemical compound. These are the new cyanopyrazine-based bullet systems. Studies have shown that the presence of cyanogroup substance in the composition of fluorophores significantly increases the efficiency of organic light-emitting diodes (OLED). This means that they can be used for create new materials to enhance the brightness of displays on smartphones, computers, and…
