superabsorbent polymer with high Swelling Ratio and temperature sensitive and magnetic properties employed as an efficient dewatering medium of fine coal
Energy & Fuels, 2017Co-Authors: Suhong Zhang, Hangchao Chen, Shengyu Liu, Jianying GuoAbstract:One novel superabsorbent polymer with temperature-sensitive and magnetic properties was prepared by the designed route. As a comparison, the other superabsorbent polymer was prepared by changing the above route. The obtained samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), transmission electron microscopy (TEM), superconducting quantum interference device magnetometer (SQUID), and gel permeation chromatography (GPC). The temperature-sensitive properties of the obtained polymers were investigated by measuring Swelling Ratios at given temperatures. The superabsorbent polymer exhibiting the preferable temperature-sensitive, magnetic properties and Swelling Ratio was employed in the dewatering process of the fine coal. The moisture mass content in the fine coal was decreased to less than 10% within the mixing time 60 min. In addition, it can be found that the polymer with relatively stab...

synthesis characterization and evaluation of Swelling Ratio on magnetic p53 poly maa co egdma go fe3o4 mip go fe3o4 based p53 protein and graphene oxide from kusambi wood schleichera oleosa
Journal of materials research and technology, 2020Co-Authors: Apris A. Adu, Yantus A.b. Neolaka, Arsel A. Pau Riwu, Munawar Iqbal, Handoko Darmokoesoemo, Heri Septya KusumaAbstract:Abstract The p53 protein plays an important role by acting as a transcription factor to regulate gene expression and its genetic mutation has been reported as the most common genetic alteRations in human cancer diseases. This opens possibilities for the development of early identification of cancer by utilizing p53 protein as tumor biomarkers. In this work we report the synthesis, characterization and evaluation of p53-poly(MAA-co-EGDMA)@GO-Fe3O4 as SPE materials for selective extraction of wild p53 protein. The magnetic material p53-poly(MAA-co-EGDMA)@GO-Fe3O4 (MIP@GO-Fe3O4) is successfully prepared with GO-Fe3O4 from kusambi wood (Schleichera oleosa) as the host material, p53 as a template molecule, methacrylic acid (MAA) as a monomer, ethylene glycol dimethacrylate (EGDMA) as a crosslinker, benzoyl peroxide (BPO) as an initiator and acetone/ethanol as a porogen. Synthesis is carried out using a bulk polymerization method. To find out the best Ratio that produces the highest MIP@GO-Fe3O4 mass, the five variations of the volume Ratio of template, monomer and crosslinker (P1–P5) are investigated. It was found that the volume Ratio of template, monomer and crosslinker that produced the highest MIP@GO-Fe3O4 mass is obtained at P3 volume Ratio (1:4:8 mL, which is further polymerized with GO-Fe3O4 as much as 0.6239 g). Swelling Ratio studies using 3 (three) solvents namely chloroform, acetone and methanol show that the Swelling Ratio values obtained are 1.46, 1.24 and 1.23 g/g, respectively. These results indicate that methanol is the best solvent for use in the rebinding process of MIP@GO-Fe3O4 material. Based on the analysis by FTIR, XRD, SEM-EDX and BET-BJH, the resulting MIP@GO-Fe3O4 material is expected to be used later for wild p53 preconcentRation from various biological samples.

Cell attachment/detachment behavior on poly(N-isopropylacrylamide)-based microgel films: the effect of microgel structure and Swelling Ratio
Journal of Materials Science, 2018Co-Authors: Yongqing Xia, Dachao Tang, Xiaojuan Wang, Meiwen Cao, Shengjie WangAbstract:Microgels are cross-linked soft particles with a three-dimensional network structure that are swollen in a good solvent. Poly(N-isopropylacrylamide) (pNIPAAm)-based microgels have attracted great attentions for their temperature responsive property, particularly in recent years, pNIPAAm-based microgel films were utilized as a new kind of thermoresponsive surface to tune cell attachment/detachment behavior via temperature stimuli. However, some results are not consistent, for example, different polymerization conditions may bring out different results even for pure pNIPAAm microgel. This work aims to find out which factor plays the critical role for successful cell detachment on the pNIPAAm-based microgel films. The results unraveled that the structure and Swelling Ratio of the microgel rather than the film thickness plays a key role on the successful cells detachment, unlike linear pNIPAAm films in which the cells’ attach/detach property is only determined by the film thickness. For poly(N-isopropylacrylamide–styrene) microgel film, NIH3T3 cells could only detach when the microgel has a uniform structure and the volume dilatation of the microgel (20/38 °C) is larger than 4.
