Lanthanide

Promethium, one of the rarest and most mysterious elements in the periodic table, has finally given up some crucial chemical secrets

While China produces the majority of the world's gallium and germanium, it is not the only producer.

The James Webb Space Telescope traced the second-brightest gamma-ray burst ever seen to a kilonova, a collision between two neutron stars — an event believed...

In 2021, lanthanide-doped nanoparticles made waves—or rather, an avalanche—when Changwan Lee, then a Ph.D. student in Jim Schuck's lab at Columbia Engineering, set off an extreme light-producing chain reaction from ultrasmall crystals developed at the Molecular Foundry at Berkeley Lab. Those same crystals are back again with a blink that can now be deliberately and indefinitely controlled.

This study was carried out under the leadership of Dr. Ming-Liang Tong (Key Laboratory of Bioinorganic and Synthetic Chemistry of Ministry of Education, School of Chemistry, Sun Yat-Sen University) and Dr. Shiping Yang (College of Chemistry and Materials Science, Shanghai Normal University).

Using the Echelle SPectrograph for Rocky Exoplanets and Stable Spectroscopic Observations (ESPRESSO), astronomers from the Chinese Academy of Sciences (CAS) have investigated the atmosphere of MASCARA-4b—a distant "ultra-hot Jupiter" exoplanet. The study, published April 11 on the arXiv pre-print server, resulted in the detection of rubidium and samarium in an exoplanet's atmosphere for the first time.

Certain species of microbes have evolved to survive in harsh environments, even those that were previously thought to be too extreme to support life. These include environments, such as mines and industrial sewage, that are rich in heavy metals. On the other hand, human exposure to toxic levels of metals, like cadmium and mercury, is known to lead to health risks, including cancer and damage to multiple organ…

Toshiba Corporation has unveiled a technology breakthrough in photoluminescence, a novel phosphor that delivers excellent solubility in polymers or organic solvents, where it is transparent and colorless under visible light, and that emits persistent red-light emissions under UV light, with excellent color purity and a luminescence six times that of current phosphors.

Strong and coherent ultraviolet light emission devices have enormous medical and industrial application potential, but generating ultraviolet light emission in an effective way has been challenging. Recently, a collaborative research team co-led by researchers from City University of Hong Kong (CityU) developed a new approach to generate deep-ultraviolet lasing through a "domino upconversion" processing of…

Scientists applied their flash Joule heating process to coal fly ash and other toxic waste to safely extract rare earth elements essential to modern electronics and green technologies.

Lanthanide-doped nanoparticles (LnNPs) can harvest the near-infrared (NIR) light to emit higher energy photons (upconversion) or lower energy photons (downshifting). In a recent study published in ACS Nano, a team led by Prof. CHANG Yulei from Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences developed a novel photoswitchable nanoparticle based on LnNPs for antitumor…

Carbon dioxide can be harvested from smokestacks and used to create commercially valuable chemicals thanks to a novel compound developed by a scientific collaboration led by an Oregon State University researcher.

Doesn't "organometallic sandwich" sound appetizing?

Samarium (Sm), a rare earth metal, is important to organic chemists because of the ability of its divalent compounds to efficiently perform single-electron transfer reductions.

Molecular compounds with heavy elements, like americium, curium and others can now be synthesized in a streamlined and efficient way thanks to a new technique developed by Lawrence Livermore National Laboratory (LLNL) researchers.

Using the James Webb Space Telescope, scientists have confirmed that neutron star mergers forge heavy elements like gold.

Researchers have developed the first fiber laser that can produce femtosecond pulses in the visible range of the electromagnetic spectrum. Fiber lasers producing ultrashort, bright visible-wavelength pulses could be useful for a variety of biomedical applications as well as other areas such as material processing.

Researchers have experimentally demonstrated a new quantum information storage protocol that can be used to create Greenberger-Horne-Zeilinger (GHZ) quantum states. There is a great deal of interest in these complex entangled states because of their potential use in quantum sensing and quantum error correction applications.

Bacteria that feed on methanol are able to grow on certain rare earth elements as well as their radioactive relatives. These findings suggest a possible role for such bacteria in the decontamination of areas where actinides are spilled, or in the separation of lanthanides and actinides for analytical or preparative purposes, according to a study published in the journal Angewandte Chemie International Edition.
