  摘要：Higher strength and higher ductility are desirable for structural materials. However, ultrastrong alloys inevitably show decreased strain-hardening capacity, limiting their uniform elongation. We present a supranano (<10 nanometers) and short-range ordering design for grain interiors and grain boundary regions, respectively, in fine-grained alloys based on vanadium, cobalt, and nickel, with additions of tungsten, copper, aluminum, and boron. The pronounced grain boundary-related strengthening ...

  摘要：The distribution of substitutional aluminum (Al) atoms in zeolites affects molecular adsorbate geometry, catalytic activity, and shape and size selectivity. Accurately determining Al positions has been challenging. We used synchrotron resonant soft x-ray diffraction (RSXRD) at multiple energies near the Al K-edge combined with molecular adsorption techniques to precisely locate single Al and Al pairs in a commercial H-ZSM-5 zeolite. This analysis depicts three distinct Al tetrahedral (T) sites...

  摘要：Maintaining genome integrity is an essential and challenging process. RAD51 recombinase, the central component of several crucial processes in repairing DNA and protecting genome integrity, forms filaments on DNA, which are tightly regulated. One of these RAD51 regulators is FIGNL1 (fidgetin-like 1), which prevents RAD51 genotoxic chromatin association in normal cells and persistent RAD51 foci upon DNA damage. The cryogenic electron microscopy-imaged structure of FIGNL1 in complex with RAD51 r...
