Understanding the nature of active sites in heterogeneous catalysts and how to create them purposefully opens up the possibility of tailored catalyst design. Here we report mixed-valence subnanometre CoOx clusters, consisting of a few metallic Co⁰ atoms on top of Co²⁺, bound to a silicalite-1 support through lattice oxygen atoms as active species for non-oxidative propane dehydrogenation (PDH) to propene. [...]

Investigating materials under extreme pressure using diamond anvil cells (DACs) requires very small samples. X-ray diffraction studies of such samples therefore require beams focused to <5 μm. [...]

CK2α and CK2α’, two paralogous members of the human kinome, are catalytic subunits of protein kinase CK2. Together with the regulatory subunit CK2β, they form heterotetrameric holoenzymes. [...]

The success of mRNA lipid nanoparticles (LNPs) used in the COVID-19 vaccines has demonstrated the significance of pharmaceutical products utilizing nanoparticle-based drug delivery systems in global healthcare. For the assessment of the safety, efficacy, and quality of these complex, multicomponent systems, it is important to consider not only the properties of the individual components but also their colloidal organization. [...]

Polaritonic chemistry has been emerging as a powerful and fundamental paradigm in materials science, offering unconventional ways to manipulate molecular and material properties by engineering light–matter interactions. By hybridizing molecular excitations with confined electromagnetic fields to form polaritonic states, this approach enables direct modulation of energy landscapes, bond strengths, and transition pathways in materials without altering their chemical composition. [...]

Context. Microquasars have emerged as promising candidates to explain the cosmic-ray flux at petaelectronvolt energies. [...]
