The results show that NGPMs are of hierarchical structure, which are composed of a lot of nanolamellas.
Thus, they have potential applications in physical electronics, optics, biomedicine and chemistry, materials science and micro-electro-mechanical systems.
Furthermore, NiO microtubes were obtained by calcining NGPMs in air atmosphere and maintained the features of the size and structure of NGPMs.

Hence, a better understanding of gases evolve during pyrolysis is essential for better understanding the structure of the residue, consequently for the utilization of residue. 
The mass loss between 250-300°C may be attributed to the loss of a small amount of pyrolysis water as a result of the decomposition of the phenolic structures, the carbonyl groups or the peroxy radicals.
In this period the H2 was generated by the integration of hydrogen free radicals which came from the broken of the macromolecular structure.
Compared with TGA curves, the gas maximum evolution temperature was related to the maximum weight loss rate temperature, which was about 490°C, because in this temperature the decomposition rate of the coal macromolecular structure is largest, and a large number of hydrocarbon formation, release, hence C2 hydrocarbons during pyrolysis mainly came from the cracking of coal macromolecular structure, the maximum gas evolution range from 400 ~ 600°C.

Effect of Super Slag Powder on Pore Structure and Compressive Strength of RPC Ping Zhang 1,2,a, Qiuyi li 2,b, Tiejun Zhao 2,c , Xiangxin Xue 1,d 1school of material & metallurgy , northeastern university, shenyang 110004, china 2school of civil engineering, qingdao technological university ,qingdao 266033, china azhangping@qtech.edu.cn, blqyyxn@163.com, d xuexx@mail.neu.edu.cn.
Key words: RPC;superfine slag powder; pore structure; compressive strength Abstract: This paper deals with RPC produced by superfine slag powder(measured specific surface area is 1824 m2/kg) and natural sands with a low water-binder ratio(0.2 or so),which strength can achieve 100MPa after 28d standand curing.

The walls of these tubes possess a hexagonal graphite structure and are capped at both ends.
Solubility and purification are vital requirements for a solution-based chemistry [7].
The aim of the XRD analysis is to reveal the crystallographic structure of MWCNTs.
The nitric acid treatment caused defects to the surface structure as a result of functionalization but retained the crystalline structure of MWCNTs, as confirmed from XRD result.
