Experimental evidence of tetrahedral symmetry breaking in SiO2 glass under pressure
Understanding the structural origin of the anomalous properties of SiO2 liquid and glass at high pressures is fundamental in wide range of scientific fields. Here, the authors find experimental evidence of a bimodal behavior in the translational order of

Probing the local emission of CaAlSiN3:Eu2+ via X-ray nanoprobe
A synchrotron source offers the advantage of continuous and tunable x rays. Therefore, not only an X-ray nanoprobe can provide the desired spatial resolution to measure the elemental distribution of CaAlSiN3:Eu2+ via X-ray fluorescence mapping but X-ray ...

Structural insights into the bi-specific cross-over dual variable antibody architecture by cryo-EM
Multi-specific antibodies (msAbs) are being developed as next generation antibody-based therapeutics. Knowledge of the three-dimensional structures, in the full antibody context, of their fragment antigen-binding (Fab) moieties with or without bound ...

Dynamics of Human Mitochondrial Complex I Assembly: Implications for Neurodegenerative Diseases
Neurons are extremely energy demanding cells and highly dependent on the mitochondrial oxidative phosphorylation (OXPHOS) system. Mitochondria generate the energetic potential via the respiratory complexes I to IV, which constitute the electron transport
