Thus, it is of great interest designing an injectable scaffolds having a proper chemistry to induce degradability while maintaining its mechanical integrity.
The results indicate that the setting and hardening process of the CPCs depend on the chemistry of the cement reactants.
Additionally, the decrease in strength can be attributed to the less entangled crystalline structure due to the non-settable β-TCP remnants in the cement [10].

Fig. 1 Schematic diagram of the electroplating system Apparatus structure In the traditional electroplating process, the deposition occurs on the whole surface which contacts the electrolyte, so the thickness distribution of the deposited layer cannot be controlled.
However, through improving the structure of the electroplating system, as shown in Fig. 2, the deposition region can be controlled and the deposition rate can be adjusted [16-17].

At 1.25 % NRL, the anatase was present in two major shapes: the 1-D nanostructures and the submicron star shape structures and their ruptured counterparts.
Overnight stirring did not alter the structure of the nanoparticles but produced some bigger particles.
In sol-gel chemistry, a higher concentration of precursor ions often leads to bigger particle [8].

Removal of chromium from aqueous solution by polymer enhanced ultrafiltration using copolymer of maleic acid and acrylic acid Lianjun Mao, Yongqian Wang, Yunren Qiu* School of Chemistry and Chemical Engineering, Central South University, Changsha, 410083, China; Key Laboratory of Resources Chemistry of Nonferrous, Ministry of education *Corresponding author, e-mail: qiu_yunren@yahoo.com.cn Keywords: Complexation; Ultrafiltration; Chromium; Wastewater treatment Abstract.
Fig.1 Structure of the PMA-100 Experimental Chemicals, membrane.
It may be explained as follows: at low P/M value, complexing sites (COO-) in the PMA-100 structure are not enough for binding all the chromium ions, causing the retention low.

Introduction The electrospinning method is simple and effective method of Preparation of fine fiber and fiber diameter by adjusting the spinning conditions (such as voltage, velocity, and distance) [1], the parameters of the solution (such as concentration, viscosity, surface tension and conductivity, etc.) as well as environmental conditions (such as temperature, humidity) control. [2] This approach has been used for the preparation of a variety of materials, fibers, fiber membrane obtained in the sensor, select high-performance filters, and tissue engineering and electronic devices with a wide range of applications.[3,4] Polyoxometalates chemistry as an important branch of inorganic chemistry in recent years has been attached great importance to the majority of scientists.
Results and discussion When the mount of PS is 2.4g, the beaded structure appeared.
The fiber was uniformly distributed, but there was still a beaded structure.

It is vital to control their crystalline structure to ensure the formation of ferroelectric β-phase which is a pre-requisite for achieving high performance in electronic devices.
The existence of four different crystalline structures in PVDF (β-, γ-, α- and d-) samples were found to be dependent on varying factors such as film thickness, sample preparation method, solvent evaporation rate, temperature and polarity of the solvent used, thermal treatment methods, etc [6,12,14-19].
