Sound-absorbing silk 17.05.2024

In a world where noise is becoming increasingly intrusive, the emergence of innovative materials that can reduce its impact is of great interest. MIT researchers have unveiled a new sound-absorbing silk fabric that promises to revolutionize quiet spaces. The Massachusetts Institute of Technology (MIT) has made significant breakthroughs in the field of sound absorption. Researchers have developed a special silk fabric that can effectively absorb sound and create cozy, quiet environments. The fabric, thinner than a human hair, contains a unique vibrating fiber that is activated when voltage is applied to it. This feature allows the fabric to be used to suppress sound waves in two different ways. The first method uses fabric vibrations to generate sound waves that cover and cancel out unwanted noise, similar to noise-canceling headphones. This p ... >>

High Energy Density Capacitor 17.05.2024

Energy plays a key role in many aspects of modern life, and the ever-increasing demand for efficient and fast-charging power sources is driving innovation. Researchers at the McKelvey School of Engineering at Washington University in St. Louis have taken a significant step forward with a high-energy-density capacitor that promises to revolutionize the world of energy. A team of scientists from the McKelvey School of Engineering at Washington University in St. Louis presented the results of their latest research on heterogeneous thin-film structures for capacitors. Researchers, working with ferroelectrics, inadvertently created a capacitor with an amazing energy density that is 19 times higher than that of conventional elements. This breakthrough opens up new prospects for the development of fast-charging batteries, which are so necessary in the modern world. Capacitors play a key role in various devices, providing stable ... >>

Causes of conflicts between brothers and sisters 16.05.2024

Family relationships are often complex and multi-layered, and conflicts between siblings are no exception. Research in this area can help us understand what factors underlie these conflicts and why they occur so frequently. Let's look at some of the findings from psychologists at Arizona State University. American psychologists from Arizona State University conducted a study aimed at identifying the causes of conflicts between brothers and sisters. They found that different forms of violence, whether physical or verbal, did not depend on the gender of the siblings. This means that both girls and boys can exhibit aggressive behavior towards their loved ones. Other studies have shown that conflict between siblings often persists into adulthood, even as contact decreases. This indicates that people often follow established patterns of behavior formed in childhood. It was also found that, despite ... >>
