Published A theory linking ignition with flame provides roadmap to better combustion engines
(via sciencedaily.com) Original source Researchers have theoretically linked ignition and deflagration in a combustion system, unlocking new configurations for stable, efficient combustion engines due to the possible existence of any number of steady-state solutions.
Published A new world of 2D material is opening up
(via sciencedaily.com) Original source Materials that are incredibly thin, only a few atoms thick, exhibit unique properties that make them appealing for energy storage, catalysis and water purification. Researchers have now developed a method that enables the synthesis of hundreds of new 2D materials.
Published Perovskite solar cells: Vacuum process may offer a short track to commercialization
(via sciencedaily.com) Original source Which process is best suited for mass production of perovskite solar cells? While solvent-based manufacturing processes are used in laboratories around the world, vacuum vapor-phase deposition processes are still the standard for the production of thin films for photovoltaics or organic light-emitting diodes. A new study that reveals major differences in the scientific discussion of these production processes.
Published Advanced army robots more likely to be blamed for deaths
(via sciencedaily.com) Original source Advanced killer robots are more likely to blamed for civilian deaths than military machines, new research has revealed. The study shows that high-tech bots will be held more responsible for fatalities in identical incidents.
Published How to upcycle low-energy light
(via sciencedaily.com) Original source To combine two low-energy photons into one high-energy photon efficiently, the energy must be able to hop freely, but not too quickly, between randomly oriented molecules of a solid. The discovery provides a much-needed design guideline for developing materials for more efficient PV cells, displays, or even anti-cancer therapies.
Published Robot ANYmal can do parkour and walk across rubble
(via sciencedaily.com) Original source The quadrupedal robot ANYmal went back to school and has learned a lot. Researchers used machine learning to teach it new skills: the robot can now climb over obstacles and successfully negotiate pitfalls.
Published New high-speed microscale 3D printing technique
(via sciencedaily.com) Original source A new process for microscale 3D printing creates particles of nearly any shape for applications in medicine, manufacturing, research and more -- at the pace of up to 1 million particles a day.
Published New AI technology enables 3D capture and editing of real-life objects
(via sciencedaily.com) Original source Imagine performing a sweep around an object with your smartphone and getting a realistic, fully editable 3D model that you can view from any angle -- this is fast becoming reality, thanks to advances in AI. Researchers have unveiled new AI technology for doing exactly this. Soon, rather than merely taking 2D photos, everyday consumers will be able to take 3D captures of real-life objects and edit their shapes and appearance as they wish, just as easily as they would with regular 2D photos today.
Published You don't need glue to hold these materials together -- just electricity
(via sciencedaily.com) Original source Is there a way to stick hard and soft materials together without any tape, glue or epoxy? A new study shows that applying a small voltage to certain objects forms chemical bonds that securely link the objects together. Reversing the direction of electron flow easily separates the two materials. This electro-adhesion effect could help create biohybrid robots, improve biomedical implants and enable new battery technologies.
Published Scientists reveal the first unconventional superconductor that can be found in mineral form in nature
(via sciencedaily.com) Original source Scientists have identified the first unconventional superconductor with a chemical composition also found in nature.
Published Spiral wrappers switch nanotubes from conductors to semiconductors and back
(via sciencedaily.com) Original source By wrapping a carbon nanotube with a ribbon-like polymer, researchers were able to create nanotubes that conduct electricity when struck with low-energy light that our eyes cannot see. In the future, the approach could make it possible to optimize semiconductors for applications ranging from night vision to new forms of computing.
Published Cicadas' unique urination unlocks new understanding of fluid dynamics
(via sciencedaily.com) Original source While most small insects and mammals urinate in droplets, cicadas urinate in jets. Researchers say the finding could be used to create better robots and small nozzles.
Published Design rules and synthesis of quantum memory candidates
(via sciencedaily.com) Original source In the quest to develop quantum computers and networks, there are many components that are fundamentally different than those used today. Like a modern computer, each of these components has different constraints. However, it is currently unclear what materials can be used to construct those components for the transmission and storage of quantum information.
Published Breakthrough in nanostructure technology for real-time color display
(via sciencedaily.com) Original source New groundbreaking technology enables the real-time display of colors and shapes through changes in nanostructures.
Published AI-generated food images look tastier than real ones
(via sciencedaily.com) Original source Researchers have announced an intriguing discovery -- consumers generally prefer AI-generated images of food over real food images, especially when they are unaware of their true nature.
Published Combined microscopy technique catches light-driven polymers in the act
(via sciencedaily.com) Original source Researchers have used tip-scan high-speed atomic force microscopy combined with an optical microscope to observe light-induced deformation of azo-polymer films. The process could be followed in real time, and the film patterns were found to change with the polarization of the light source. The observations will contribute to the use of azo-polymers in applications such as optical data storage, and the approach is expected to be useful across materials science and physical chemistry.
Published How surface roughness influences the adhesion of soft materials
(via sciencedaily.com) Original source A research team discovers universal mechanism that leads to adhesion hysteresis in soft materials. Through a combination of experimental observations and simulations, the team demonstrated that roughness interferes with the separation process, causing the materials to detach in minute, abrupt movements, which release parts of the adhesive bond incrementally. The findings will make it possible to specifically control the adhesion properties of soft materials through surface roughness and will allow new and improved applications to be developed in soft robotics or production technology in the future.
