Abstract:  Dimethylamine borane (DMAB) has been considered as one of the important hydrogen sources with a simple process by the help of the efficient catalyst. For this purpose, herein, platinum nanoparticles (Pt NPs), placed inside carbon black hybrid (Pt NPs@CBH), activated carbon (Pt NPs@AC) and Vulcan carbon (Pt NPs@VC), have been prepared as highly monodisperse catalysts for dehydrogenation reactions of DMAB at room temperature. The morphological and physical structure of the monodisperse catalysts have been identified by X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HRTEM) etc. The typical face-centered cubic (fcc) structure of the all prepared catalysts was verified from X-ray diffractogram. All prepared catalytic materials were measured as high-performance catalysts for dehyrocoupling of DMAB; but, Pt NPs@CBH catalyst indicated the better catalytic activity compared to the other prepared ones. Easy utilization at very small concentrations and temperature, monodisperse Pt NPs@CBH perform an eye-catching catalytic activity with providing one of the best TOF (70.28 h-1) and Ea (93.56 ± 2 kJ/mol) for dehydrocoupling of DMAB.

  For the model construction, the Reserpine was injected into the ventricle of the mice  Reserpine was injected into the ventricle of the mice to establish the mania mice model References would be useful here, to show that intra-ventricle injections of reserpine does indeed produce the desired state. I would also have thought that the **quantity** of reserpine required for creation of manic mice would be important information for anyone wanting to replicate or extend this research. If the authors don t know those details, one speculates whether the experiments took place. , 
  The neuroregulin1 (NRG1) in the hippocampus and the ErbB4 on the noradrenergic neurons play important roles in the development of mania.[1,2] After the binding of the NRG1 with its receptor ErbB4, it could stimulate the down-stream signaling pathway and lead to the abnormal neuronal discharge, which finally leading to the production of mania.[3] Do these references mention NRG1 or ErbB4? Or did they just come out of a cursory Google search? - [1]. Martu0001u0131nez, R. A.; Rodr u0001 u0001u0131guez, R. M. T.; Ariza, M. A.; Spuch, C.; u0001 Olivares, J. M.

Schiff base ligands are easily prepared and can react with almost all metal ions to form complexes.[8u201310] I am not sure that an asphalt steel-slag aggregate is a good example of a Schiff base ligand. - [9].

This nonsensical reference turns up dozens of times in this *oeuvre*, almost as if papers were bring mass-produced. ,
