Researchers explore the transformation dynamics of cubic liquid crystals using direct simulation and machine learning, offering new possibilities for advanced materials development. Researchers have uncovered key insights about how liquid crystals, materials capable of forming complex ordered structures, transform between different phases. Published in PNAS, the study provides a clearer understanding of how these materials

The asteroid that led to the extinction of the dinosaurs 66 million years ago probably came from the outer solar system. Geoscientists from the University of Cologne have led an international study to determine the origin of the huge piece of rock that hit the Earth around 66 million years ago and permanently changed the
A groundbreaking technology has been unveiled that improves the efficiency of thermoelectric materials, which are key in converting waste heat into electricity, by altering their geometry to resemble an hourglass. Unlike previous research that solely depended on the material properties of thermoelectric substances, this new approach is expected to have widespread applications in thermoelectric power
A study expands understanding on how electrons move through the conductive parts of complex fluids found in electrochemical devices such as batteries. This work can help overcome existing knowledge gaps for engineers seeking to improve the performance of these devices. Thomas Edison went through thousands of materials before he finally found the right tungsten filament
Researchers have demonstrated a technique for printing thin metal oxide films at room temperature, and have used the technique to create transparent, flexible circuits that are both robust and able to function at high temperatures.

Noble gases have a reputation for being unreactive, inert elements, but more than 60 years ago Neil Bartlett demonstrated the first way to bond xenon. He created XePtF6, an orange-yellow solid. Because it's difficult to grow sufficiently large crystals that contain noble gases, some of their structures -- and therefore functions -- remain elusive. Now
Microscope images could be obtained much more quickly -- rather than one pixel at a time -- thanks to a new imaging method for neutral atomic beam microscopes. It could ultimately lead to engineers and scientists getting faster results when they are scanning samples. Microscope images could be obtained much more quickly -- rather than
Researchers have found a better method to recycle polyurethane foam from items like mattresses: They are not only able to break down PUR and separate the two main components -- they can do it in one go. This is great news for the budding industry that aims to chemically recover the original components of the
Society relies heavily on diverse fluidic technologies. The ability to precisely capture and release various chemical and biological fluids plays a fundamental role in many fields. A long-standing challenge is to design a platform that enables the switchable capture and release of liquids with precise spatial and temporal control and accurate volumes of the fluid.
The finding could help future efforts to design superconductors that work at higher temperatures. For the past century since their discovery, superconductors and their mysterious atomic properties have left researchers in awe. These special materials allow electricity to flow through them without any energy loss. They even allow trains to levitate. But superconductors typically only
Physicists have uncovered new states of matter by exploring the behavior of flatland electrons in extreme conditions, revealing insights that could impact quantum computing and advanced materials. Imagine a two-dimensional flatland, instead of our three-dimensional world, where the rules of physics are turned on their head and particles like electrons defy expectations to reveal new

A new algorithm may make robots safer by making them more aware of human inattentiveness. In computerized simulations of packaging and assembly lines where humans and robots work together, the algorithm developed to account for human carelessness improved safety by about a maximum of 80% and efficiency by about a maximum of 38% compared to
