Humic acids are biological macromolecules. It has been 500 years since “WU-JIN-SAN” (i.e. humic acid) reported in Compendium of Materia Medica. In recent 30 years tens of medical companies and institutions have done regular clinical trials, toxicological and harmacological research on bio-humic acids. Besides, German, Polish, Swiss, Finland et al. have also done similar research, with the similar efficacy of Chinese herbal medicine like “Streagthening Vital Qi's Capacity to Resist Pathogens”, “Readjusting Yin and Yang”, “remedy defects and rectify errors” which build a scientific fundament for medical application of bio-humic acid. Although bio-humic acids was relatively weak in pharmacological studies, it was still traceable. As a drug, how to make a prescription in the pharmacopoeia? This is the key issues which affect the progress in humic medical research. The author consider: First, the use of low-carbon biodegradation reduces the complexity of bio-humic acid molecules,then acoording to the active component by bio-humic acid, Pharmacological-pharmacodynamic, and determining the scope of medical applications could gradually overcome the bottleneck of medical research in bio-humic acid, accelerat the progress of medical research of bio-humic acid.

The branched polyethylene (br-PE) was synthesized by [ArN=C(An)-C(An)=NAr]NiBr2 (An = acenaphthyl, Ar = 2,6-C6H3(iPr)2) in the presence of modified methylaluminoxane (MMAO) and methylaluminoxane (MAO). The effects of experimental conditions in which ethylene pressure, temperature and time were varied on ethylene polymerization were investigated. The structures of the obtained polyethylene were characterized by high-temperature NMR, high-temperature GPC and DSC. It was found that the activities from MMAO were higher than that from MAO about 10 times, which reaches 107(g/mol Ni·h). The branches of polyethylene prepared from MMAO were about 60/1000C, while that from MAO were about 80/1000C. The branched polyethylene with 84 branches / 1000C was used to toughen isotactic polypropylene (i-PP). The results show that the impact strength of blends improves as the content of branched PE increases. When the content of br-PE is 40%, the impact strength of the blend reaches to 50.24 KJ/m2, which is about twenty times that of PP (2.24 KJ/m2).

Constructed matrices and artificial neural network numerical simulation method are used to transform , regulate and control carbon black (CB) reactor, where nano-conductive carbon black (NCCB) of low resistivity and good dispersion can be produced on the base of coal tar-based CCB production process. This kind of high-quality CCB with corrosion resistance and low expansion is used in high power electrodes, capacitors, etc.
