You may have noticed that the rock formations are very different colors. The rock formations on the left are from Red Rock State Park in Texas, and on the right is El Capitan Mountain in Yosemite ...

Selenium-based compounds play vital roles in human and animal health; however, accurately detecting their various forms has long been a challenge. Researchers from Chiba University have developed a ...

Scientists have found the first case of an ionic crystal consisting of just one chemical element -- boron. This is the densest and hardest known phase of this element. The new phase turned out to be a ...

Chemists have developed a method to furnish a range of molecules with a trifluoromethyl group attached to a sulfur, nitrogen or oxygen atom. Their procedure avoids the use of PFAS reagents. It thus ...

Helium — the recluse of the periodic table — is reluctant to react with other elements. But squeeze the element hard enough, and it will form a chemical compound with sodium, scientists report. Helium ...

Students will learn how to categorize matter as either pure substances or mixtures. Students will apply tests, based on physical properties of matter samples, to determine whether a mixture is ...

Each atom and molecule has its own fingerprint that, like yours, is unique. But unlike yours, this fingerprint is made of light. Elements and compounds emit identifying sets of “colors,” or ...

Scripps Research chemist Matthew Disney, PhD, and colleagues have created drug-like compounds that, in human cell studies, bind and destroy the pandemic coronavirus' so-called "frameshifting element" ...

Versatile Bonding: Sulfur is highly versatile in its bonding behavior, forming compounds with a wide range of elements. This is due to its ability to adopt different oxidation states and form various ...

The catchphrase "bazinga" — a zinger commonly uttered by Dr. Sheldon Cooper, a fictional theoretical physicist on the TV show "The Big Bang Theory" — has inspired the creation of a novel compound, ...

Although present in very small amounts, selenium (Se)-based compounds play important roles in protecting the body from ...
