A sodium polyacrylate-mediated strategy was employed to prepare well-defined MoS 2 ball-flower-like nanomaterials. It was found that the polyacrylate acted as a morphology-directing agent to promote MoS 2 nanosheets to self-assemble into ball-flowers with 3D hierarchical structures. Moreover, as an electrode applied in a supercapacitor, the ball-flower-like MoS 2 exhibited a remarkable pseudocapacitive performance such as a high specific capacitance and superior cycling durability.

In this work, the 3D porous hierarchical MoS2 nanostructures were prepared via a simple hydrothermal deposition method only utilizing titanium (Ti) mesh as a substrate. The as-synthesized uniform MoS2 flower-like nanostructures were assembled by nanosheets composed of several stacking layers. The curved and rough surface of cylindrical Ti wire was beneficial to assembly of MoS2 nanosheets into hierarchical architectures. Moreover, the electrochemical performance of the as-prepared MoS2 nanostructured electrodes for capacitors was also investigated. The structural advantages lead to a remarkably improved pseudocapacitive property including high capacitance and durable cycling ability.

Thermal decomposition processes taking place in solid state complex of Zn 1-x Mn x C 2 O 4 •2H 2 O have been investigated in air using TG-DTG/DTA, XRD and TEM techniques. TG-DTG/DTA curves showed that the decomposition proceeded through two well-defined steps with DTA peaks closely to correspond to the weight loss. XRD
