Amber, a fossilised resin, became widespread during the Barremian ( ~ 122 Ma), marking the onset of the Cretaceous Resinous Interval (125–72 Ma). While common in the Northern Hemisphere, amber containing terrestrial arthropod inclusions had not previously been reported from the Mesozoic of South America [...]

Here we report the straightforward synthesis of a novel nanographene, syn-dinaphthopentacene. This new compound was prepared along with its isomer anti-dinaphthopentacene to compare how small structural differences may affect properties such as crystal packing, photostability, and device performance [...]

Carbon, nitrogen, and hydrogen are among the most abundant elements in the solar system, and our understanding of their interactions is fundamental to prebiotic chemistry. CH4 and N2 are the simplest archetypical molecules formed by these elements and are both markedly stable under extremes of pressure. [...]

Through high-pressure diamond anvil cell experiments, we report the synthesis of two novel potassium superhydrides (KH9-I and KH9-II) and investigate their structural and vibrational properties via synchrotron X-ray powder diffraction and Raman spectroscopy, complemented by density functional theory (DFT) calculations. Above 17 GPa at room temperature, KH-II and H2 react to form KH9-I; this reaction can be accelerated with temperature. [...]

We have measured the core-valence double ionization spectra of carbon suboxide above both the O 1s and C 1s edges. Following several core-valence cases known in the literature, to begin with the spectra are compared with the well-known single ionization valence photoelectron spectrum of this system, from which they surprisingly differ quite strongly [...]

Fundamental insights into complex quantum phases of many-body systems can be ob-tained by the investigation of the underlying particle interactions. The variety of compet-ing interactions between particles involved determines their behaviour in these quantumphases. [...]

As the demand for hydrogen production increases, the economic viability and stability of Ir-based catalysts are crucial in proton exchange membrane water electrolysis (PEMWE). In this study, stable low-loading Ir electrodes (0.2 mgIr cm–2) with nanometer-thick electrodeposited layers are prepared on Pt-deposited Ti felts [...]

Polar metals have attracted growing interest due to both their significance in fundamental science and their potential functionalities. Here, we report the discovery of a novel polar metal, magnesium chloride Mg$_3$Cl$_7$, in which the metallicity of the polar structure is uniquely driven by attractive halogen interactions [...]

Graphitic carbon nitride (g-C3N4), melamine, and their derivatives are of significant interest due to their diverse structural properties and potential applications in catalysis, energy storage, and materials science. In this study, two new compounds, both with the Pb3(C3N6) chemical formula, were synthesized at pressures of 40(2) to 48(2) GPa through a direct reaction between Pb, C and N2, or Pb and C6N4, in laser-heated diamond anvil cells.
