Researchers have deployed chemicals to individuals on three continents, they found that no two wristbands had identical chemical detections. But the same 14 chemicals were detected in more than 50 percent of the wristbands returned from the United States, Africa and South America.
Researchers demonstrated enzyme-like heterogeneous catalysis for the first time. They developed a highly active heterogeneous TiO2 photocatalyst incorporated with many single copper atoms. They used this catalyst for the photocatalytic hydrogen production, and found that the catalyst is as active as the most active and expensive Pt-TiO2 catalyst.
The Earth’s magnetic field experiences unpredictable, rapid, and intense anomalies that are known as geomagnetic jerks. The mechanisms behind this phenomenon had remained a mystery until the recent research. Scientists have now created a computer model for these geomagnetic jerks, and provided an explanation for their appearance.
A transition from coal-based energy to cleaner-burning gas has long been viewed as a staple of many climate action plans, despite concerns over leakage and possible harmful emissions. A recent study finds that not only is such a shift central to meeting climate targets and stabilizing global temperature rise, but that the benefits of cleaner-burning gas outweigh its possible risks.
Scientists report that they discovered spontaneous oscillations in microfluidic droplet networks. The scientists have successfully modeled network channels similar to our blood capillaries in the simplest way containing one or two loops. They also suggest that collision between blood cells and irregularity of thickness can dampen oscillations in the biological networks. This study can help us understand the emergence and corresponding behavior of the oscillations of blood flow in the microvascular networks.
Researchers have developed a new method for safely prolonging battery life by inserting a nano-coating of boron nitride (BN) to stabilize solid electrolytes in lithium metal batteries. The team focused on solid, ceramic electrolytes, which show promise in improving safety and energy density, compared with conventional, flammable electrolytes in Li-ion batteries. Rechargeable solid-state lithium batteries they are promising candidates for next-generation energy storage.
A new perspective paper establishes a framework to apply rigorous mathematical models of uncertainty originally developed for non-social situations, such as whether or not to purchase a lottery ticket, to social scenarios such as determining an interviewer’s opinion of an interviewee.
