Asphalt is most commonly used on roads, but is also used to pave playgrounds, bike paths, running tracks, tennis courts, and basketball courts. Exposure to harmful asphalt fumes, especially sun exposure [more…]
According to the instability of oxygen-28, its neutrons are not arranged properly in the shells. Maria Goeppert Mayer discovered in the late 1940s that certain nuclei—especially those with 2, 8, 20, 28, 50, and 82 protons or neutrons—were similar [more…]
Although hydrogen production is seen as a potential replacement for fossil fuels, the processes either produce too much carbon dioxide or are too expensive. Obtaining hydrogen from plastic garbage by Rice University researchers [more…]
The stability of seawater electrolysis was increased by scientists by clarifying the corrosion mechanism of the corrosive anion Br- on Ni-based anodes. The study was published in the journal Nature Communications. Hydrogen production by electrolysis of salt water, [more…]
The printing press is called the most important invention of the last thousand years. This honor has often been given to Johannes Gutenberg, a 15th-century German craftsman. However, 78 years after Gutenberg printed the first copy of the Bible. [more…]
The first biomolecules were produced through reactions catalyzed by nitrogen-doped graphite. Necessary for the survival of the first biological molecules on Earth, the sun induced critical reactions and acted as a catalyst to speed up chemical reactions. [more…]
A new study in BESSY II examines the occurrence of skyrmions in ferrimagnetic thin films of dysprosium and cobalt, using high spatial resolution and real-time analysis. This is precision with skyrmions of suitable materials in the future. [more…]
Researchers at the University of Sydney have for the first time used a quantum computer to directly monitor and design a process crucial in chemical reactions by slowing it down 100 billion times. between and within molecules [more…]
Researchers have developed a micrometer-thin battery that can power smart contact lenses and can be charged with a saline solution. Researchers from NTU Singapore have developed a smart contact that can store electricity when immersed in a saline solution. [more…]
The researchers succeeded in creating more vortex-free helium droplets, developing a device that can be used in a wide range of experiments. Superfluid helium has long occupied the imagination of scientists since its discovery in the 1930s. [more…]
Mercury poses a risk to children due to its cold appearance, as it is the only metallic element that is known to be in liquid form at normal Earth temperature and pressure and is dangerous to humans. However, mercury [more…]
Tiny gold "seed" particles, a key ingredient in one of the most popular nanoparticle formulations, were created by Rice University chemists to form 1985-atom spherical globules associated with carbon buckyballs, first described by Rice researchers in 32. [more…]
The French Center for Scientific Research (CNRS) and the National University of Singapore (NUS) Department of Biological Sciences have joined forces to create a unique protein mimic that can self-assemble into porous structures. Pores have a lipid membrane [more…]
Nucleons like protons and neutrons make up atomic nuclei, and the nuclear force or strong interaction is what holds them together. Protons and neutrons can form bound states thanks to this force, but [more…]
Researchers examine an overlooked mode of weathering that has implications for fundamental physics and the dating of some of the oldest rocks in the Earth and Solar System. Potassium-40 has a half-life of 1,25 billion years, so [more…]
Many scientists are skeptical of claims that researchers have developed a new room-temperature ambient-pressure superconductor. If rumor has wings, extraordinary scientific claims have jet engines. a South Korean [more…]
The discovery of the lithium-ion battery is attributed to John B. Goodenough, a professor at the University of Texas at Austin, who died Sunday at the age of 100. In addition to being a talented but humble inventor, Goodenough is dedicated to his work. [more…]
First developed in 2004, high entropy alloys (HEAs) are alloys composed of several major elements in nearly equal atomic ratios. Due to their special chemical composition resulting in high levels of chemical disorder or entropy [more…]
Almost all materials, whether solid, liquid or gas, expand and contract in response to changes in temperature. The phenomenon known as thermal expansion, which causes a hot air balloon to float, [more…]
The directions and rates of acoustic wave propagation in the type of iron that forms the core of the Earth may have been clarified by laboratory tests. By examining the unexplored paths in the pressure-temperature phase space, the researchers found that the structure it most likely took in the Earth's core. [more…]
Song Lin and his colleagues at Cornell University, in a study recently published in the journal Nature, show how pairs of freeing radicals can work well together to activate CH bonds on saturated carbon atoms. [more…]
Researchers have taken a step towards a new kind of quantum processing by demonstrating a phenomenon known as Rydberg blockade (the interaction between an atom and a molecule). To be able to perform quantum calculations using these states [more…]
According to recent research, asphalt is a source of toxic compounds, but scientists are trying to improve it while minimizing its carbon footprint. Millions of kilometers of asphalt material roads around the world, as well as walking paths, [more…]
In quantum computing based on superconducting circuits, selective interaction with left and right propagation modes can enable directional information flow. The concept of reciprocity is when a source emits a wave scattered from an object and [more…]
A new and exotic state of matter has been discovered by squeezing subatomic particles into an incredibly dense crystal. By passing a strong beam of light through two chemical compounds, scientists created new excitons. [more…]
An invention may clarify whether living molecules are right- or left-handed. Research shows that the first biomolecules were bent by magnetic materials. Left and right of some molecules necessary for life [more…]
It was a difficult prospect for the study of nuclear forms. But this phenomenon may have been discovered. We are talking about an unstable sodium nucleus with an excited state and a spherical wave function. Wave functions of a nucleus [more…]
The atomic number of the chemical element palladium is 46 and its symbol is the letter Pd. English chemist William Hyde Wollaston discovered this rare and shiny silvery-white metal in 1803. Named after Pallas, the Greek goddess [more…]
Researchers have detected that there are complex organic molecules in the galaxy, 12 billion light years away from Earth. This distance took its place in the records as the farthest of those detected so far. This new study [more…]
Contrary to theoretical assumptions, experiments reveal that the density of bonding structures governs the adhesive behavior of so-called relational polymers. “Pull-out” polymers – chemical structures that form easy-to-break bonds – drip-free paint and self- [more…]
