Optimizing surface active sites via burying single atom into subsurface lattice for boosted methanol electrooxidation.

The precise fabrication and regulation of the stable catalysts with desired performance still challengeable for single atom catalysts. Here, the Ru single atoms with different coordination environment in NiFeN lattice are synthesized and studied as a typical case over alkaline methanol electrooxidation. The NiFeN with buried Ru atoms in subsurface lattice (NiFeN-Ru) exhibits high selectivity and Faradaic efficiency of methanol to formate conversion.

[The observe of clinical effect of treating lumbar intervertebral disc herniation by bone setting manipulation of different directions].

Objective: To compare the effect between lumbar backwards flexion manipulation and rotating manipulation for treating lumbar intervertebral disc herniation.

Methods: Two hundred and nine patients of lumbar intervertebral disc herniation, male 131, female 78, the age from 20 to 79 years old, 58 cases of all these patients age above 50. According to diagnosis the ladder of the 92 cases bulging type, 69 hernia type, 48 cases free type.
