Boron carbide is a material of choice for multiple industries, e.g., aerospace, as a lightweight structural ceramic due to its high hardness, high melting temperature, and low density. However, its mechanical properties have been observed to radically degrade under shockwave compression, presumably as a consequence of stress-induced phase transitions resulting in its partial amorphization [...]

It is well established that a significant amount of heat produced in the Earth’s mantle is due to the decay of uranium. However, uranium cannot be incorporated in large amounts into the most common mantle minerals [...]

Hydrogen-free melaminate salts $M_3(C_3N_6)$ (M = Cd, Ca) were synthesized in laser-heated diamond anvil cells at 34–48 GPa and 2000–2500 K. Cd$_3$(C$_3$N$_6$) was synthesized via a direct reaction between the elements, while $(Ca_3N_6)$ was obtained following a rational chemical design approach from calcium carbodiimide, Ca(NCN), which served as a single-source precursor [...]

Electrocatalyst degradation, often caused by oxidative processes, forms a large barrier for the wide-spread application of electrolysers and fuel cells, which are crucial for a sustainable energy society. A detailed understanding of the catalyst surface structure under oxygen evolution reaction (OER) conditions is, therefore, required to design more stable catalysts [...]

This paper presents the first measurements of the azimuthal anisotropy coefficients vn, which quantify the nth-order Fourier modulation of charged-particle azimuthal distributions, for n=2−4 in $\sqrt{s_\mathrm{NN}}$ = 5.36 TeV $^{16}$O+O$^{16}$ and $^{20}$Ne + Ne$^{20}$ collisions recorded with the ATLAS detector at the CERN Large Hadron Collider in 2025. The $v_n$ coefficients are measured as a function of transverse momentum $(p_T)$, collision centrality, and event multiplicity. [...]

The functionality of ionomeric membranes is influenced by small changes of several parameters. Aqueous network formation by phase separation between the hydrophilic andhydrophobic parts of the polymer is one critical factor for water and ion transport. [...]

All-solid-state batteries (ASSBs) have gained much interest in recent yearsbecause they promise higher energy and power densities as well as improvedsafety over lithium-ion batteries (LIBs). This is achieved by using nonflammablesolid electrolytes (SEs) together with lithium metal or high-capacitysilicon anodes. [...]

In the development of sustainable Na-ion battery cathodes, the use of earth-abundant elements, such as iron, is essential to reduce costs and mitigate reliance on scarce transition metals. However, Fe-based layered oxides frequently exhibit complex redox behavior and structural instability, making it crucial to understand how Fe affects the redox properties and phase evolution during cycling. [...]

GalC8 [l-threo-d-galacto-octitol, systematic name (2S,3R,4R,5R,6R,7S)-octane-1,2,3,4,5,6,7,8-octol] crystallizes with a pseudo-tetragonal lattice featuring a long (~88 Å) c axis. The bulk of the structure possesses P43212 (Z = 1) pseudo-symmetry, whereby molecules are arranged linearly with eight molecules in a translation period, thus explaining the long c axis. [...]
