Study reveals that cobalt ions, rather than the covalent organic skeleton itself, promote catalytic activity
a) Schematic diagram of the synthesis of TpBpy-Co COF. b) PXRD patterns of TpBpy and TpBpy-Co (Cu Kα1). c) N2 adsorption (filled) and desorption (empty) isotherm profiles at 77 K. Credit: Advanced Science (2024). DOI: 10.1002/advs.202413555 Covalent organic frameworks (COFs) are less stable catalysts than previously thought, but they maintain high activity. COFs are promising designer catalysts, including in the…

WEAVE spectrometer reveals duality of galactic shock
Superimpose the WEAVE decomposition of Stephan’s Quintet gas onto the JWST image. Red highlights gas shocked by collisions, while green and blue indicate star-forming regions. Purple areas represent unexplained bubbles. The black contours indicate neutral hydrogen, and its position relative to the shocked gas (red) shows where it came from. Credit: Arnaudova et al. A team of more than 50…

Research reveals earliest evidence that humans used fire to shape Tasmania’s landscape
Emerald Swamp, Three Hammock Island. Credit: Simon Haberle Some of the first humans to arrive in Tasmania more than 41,000 years ago used fire to shape and manage the landscape, some 2,000 years earlier than previously thought. A British-Australian research team analyzed charcoal and pollen in ancient mud to uncover how Tasmanian indigenous people shaped their surroundings. This is the…

Discovery of 2,586 orphan genes in Rosa chinensis reveals stress adaptation and floral development
Steps to identify orphan genes in the R. chinensis genome. Credit: Tropical Plants (2024). DOI: 10.48130/tp-0024-0036 Orphan genes, found only in specific lineages, are important drivers of new functions and phenotypic traits. This discovery lays the foundation for understanding how roses grow under environmental challenges. Rosa chinensis, a beloved ornamental plant, is a mainstay in the horticultural world. Despite their…

High-resolution IR spectroscopy reveals new insights into hydrogen bonding in hydrogen sulfide
Far-infrared spectrum of H2S-H2S at T = 0.37 K calculated using ab initio intermolecular potentials and dipole functions. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-53444-6 At first glance, water and the foul-smelling molecule hydrogen sulfide don’t seem to have much in common. However, if you invest a little energy, some differences will disappear. At first glance, the smell of soft drink…

Ultrafast imaging technology reveals how ozone-depleting molecules react to light
A long-predicted ultrafast pathway in the UV photochemistry of bromoform has been visualized for the first time by femtosecond time-resolved electron diffraction. Credit: Melody Li, Debadarshini Mishra, Lars Hoffmann Researchers have observed for the first time how bromoform rearranges its atoms in less than a trillionth of a second after being subjected to an ultraviolet (UV) pulse. The imaging technique…
