Bismuth

KIT researchers lay the foundation for new materials and chemical processes by synthesizing an unusual molecule. Researchers at the Karlsruhe Institute of Technology (KIT) have successfully synthesized and stabilized a Bi₅⁻ ring—a molecule composed of five bismuth atoms—within a metal complex. Th

A reader recently requested a chemistry lesson about bismuth. Why?? Beats me. It takes all kinds. Some people eat sweetbreads and some like nipple clamps. What follows may or may not be worse.

China and the U.S. engaged in a trade war in 2018 when Trump raised tariffs on Chinese goods and China responded in kind.

By going vertical instead of staying flat, components can be stacked up, meaning much smaller footprints for our electronics – and we all want our devices smaller...

Scientists discovered a method to create element 116 using a titanium beam, paving the way for future synthesis of element 120, the "holy grail" of chemistry.

Researchers achieved record-breaking electron mobility with a new material, paving the way for revolutionary advances in electronic devices and technology.

The team's liquid battery uses standard water with a few added salts in place of traditional electrolytic fluid like sulfuric acid or lithium salt to enable the...

Arsenic has a well-deserved reputation as a poison; in ancient times it was known as the "Poison of Kings and the King of Poisons." But arsenic, an element found naturally in soil, air, and drinking water, also has beneficial uses. How should we think about arsenic in terms of human health?

Human activity, from burning fossil fuels and fireplaces to the contaminated dust produced by mining, alters Earth's atmosphere in countless ways. Records of these impacts over time are preserved in everlasting polar ice that serves as a sort of time capsule, allowing scientists and historians to link Earth's history with that of human societies. In a new study, ice cores from Antarctica show that lead and other…

In the relentless battle against antibiotic-resistant superbugs, science continues to unveil ingenious strategies to address their vulnerability. Like other bacteria, superbugs have a unique weakness—their dependence on iron for growth and survival. Iron serves as an essential nutrient that bacteria utilize for various cellular processes, including DNA replication, energy production, and other vital functions. In…

Photoelectrochemical (PEC) water splitting is an ideal approach for converting solar energy into green hydrogen, and the controllable preparation and easy scalability of efficient photoanodes are crucial for practical application. Monoclinic phase bismuth vanadate (BiVO4) is a promising photoanode due to wide visible light utilization and good photoelectrochemical stability.

(CNN) — There isn't a one-size-fits-all answer for how often you should poop, but when it comes to what color your stool should be, expert consensus is much narrower. And deviations from it can be a cause for concern. "The most common color is brown, shades of brown," said Dr. Mark Corkins, division chief of …

Electronic nematic order in kagome materials has thus far been entangled with charge density waves. Now it is finally observed as a stand-alone phase in a titanium-based Kagome metal, a team of researchers led by Boston College physicists reported recently in Nature Physics.

This futuristic new liquid-metal coating can make ordinary objects extraordinary.

Entropic repulsion caused by interfacial orientational fluctuations of cholesterol layers restricts protein adsorption and bacterial adhesion, providing a conceptually new physicochemical perspective on biointerfaces that may guide future material design in regulation of adhesion.

Up until 2002, we thought that the heaviest stable element was bismuth: #83 on the periodic table. That's absolutely no longer the case.

A research team led by Prof. Qin Xiaoying from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has improved the thermoelectric performance of an n-type transition metal selenide, Bi2Te2.7Se0.3 (BTS), by incorporating MnSb2Se4 (MSS) nanoinclusions. Results were published in two articles in the Chemical Engineering Journal.
