The electrochemical nitrogen reduction reaction (NRR), as an environmentally friendly method to convert nitrogen to ammonia at ambient temperature and pressure, has attracted the attention of numerous researchers. However, when compared with industrial production, electrochemical NRR often suffers from ...
Here we determine the 3D atomic positions of M/HEA nanoparticles using atomic electron tomography36 and quantitatively characterize the local lattice distortion, strain tensor, twin boundaries, dislocation cores and chemical short-range order (CSRO). We find that the high-entropy alloys have larger ...
Atomic Structure refers to the fundamental components of matter, namely atoms, which consist of a nucleus and orbiting electrons. The nucleus, acting as the center of an atom, is positively charged and has a much greater mass than the negatively charged electrons. Atoms are electrically neutral ...
Figure 1. Atomic structure of the H. volcanii SLP csg (A) Cryo-ET slice through the surface of an H. volcanii cell. Density (black) corresponding to the S-layer is marked, showing a tight association with the membrane. (B) The csg protein contains six domains (D1–D6), colored blue...

The control of single metal atomic sites has been extensively studied in the field of single atom catalysts. By contrast, the precise control of the mesoporous structure in the matrix material, which directly correlates with mass diffusions and may play a dominant role in delivering industrially rel...
Both water and hydrocarbons (ammonia and methane) are needed to hydrate and fertilize the Martian soil and Titanian hydrocarbon stocks are still needed for the synthetics, agriculture, and plastics industries. Amount of expenditure viable for interplanetary military assets is one-fifth of the value ...
Both techniques showed the trimeric structure of AmtB in which each monomer seems to have a pseudo-two-fold symmetry. This arrangement is likely to represent the in vivo structure. This work provides the first views of the structure of any member of the Amt family. 展开 ...
