Only musicians can understand how grueling and challenging it is to play the violin. Violins, even mediocre ones, are worth thousands of dollars. Good news for music students and beginners, they will meet with low-cost and durable 3D-printed violins thanks to The Acoustical Society of America’s AVIVA Young Artists Program.
As stated in the release, today in Nashville, Mary-Elizabeth Brown, director of the AVIVA Young Artists Program discussed the steps taken and the lessons learned in her presentation, Old meets new: 3D printing and the art of violin-making.

Imagine having an autonomous RV.
We all love and dream of having an RV, but having an electric-powered autonomous RV could be the ultimate dream. There are many RV designs on trucks, but having an autonomous truck that drives you anywhere you wish while doing the chores could be the future of both transport and housing.
Based on the specifications Tesla revealed this week and how amazing these renderings of the electric truck as a motorhome appear, the Tesla Semi may become a fantastic electric-powered luxury RV.

Researchers around the world are on a mission to relieve a bottleneck in the clean energy revolution: batteries. From electric vehicles to renewable grid-scale energy storage, batteries are at the heart of society’s most crucial green innovations—but they need to pack more energy to make these technologies widespread and practical.
Now, a team of scientists led by chemists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and Pacific Northwest National Laboratory (PNNL) has unraveled the complex chemical mechanisms of a battery component that is crucial for boosting energy density: the interphase. Their work published today in Nature Nanotechnology.

Hydrogen fuel cell cars emerged as an alternative to both the electric and combustion engine vehicle in the early 2000s. They were widely considered an avenue toward universal green motoring.
Researchers in the CEST group have published a study demonstrating the effectiveness of machine learning methods to identify suitable perovskite solar cell materials. Perovskite solar cells are a novel technology gathering a lot of interest due to their high efficiency and potential for radically lower manufacturing costs when compared to the traditional silicon-based solar cells.
Despite their promising qualities, the commercialization of perovskite solar cells has been held back by their fast degradation under environmental stresses, such as heat and moisture. They also contain toxic substances that can negatively impact the environment. The search for new perovskite materials that do not have these problems is ongoing, but the established experimental and computational research methods have not been able to handle the high number of material candidates that need to be tried and tested.
CEST members Jarno Laakso and Patrick Rinke, with collaborators from University of Turku and China, developed new machine learning-based methodology for rapidly predicting perovskite properties. This new approach accelerates computations and can be used to study perovskite alloys. These alloy materials contain many candidates for improved solar cell materials, but studying them has been difficult with conventional computational methods.
Over the past few decades, engineers and material scientists have created increasingly advanced and efficient solar technologies. Some of these technologies are based on photovoltaics with a so-called heterojunction structure, which entails the integration of two materials with distinct optoelectronic properties.
Researchers at Technische Universität Dresden have recently realized a different type of solar cells, referred to as phase heterojunction (PHJ) solar cells. These cells, introduced in a paper published in Nature Energy, were fabricated using two polymorphs (i.e., structural forms) of the same material, the perovskite CsPbI3, instead of two entirely different semiconductors.
“The realization of a PHJ requires the ability to fabricate two different phases of the same perovskite composition on top of each other,” Yana Vaynzof, lead author of the paper, told TechXplore. “While the fabrication of CsPbI3 perovskite by solution-processing is well established in the literature, we needed to develop a method to deposit a perovskite without dissolving the underlying layer, so we decided to use thermal evaporation for this purpose.”
