3D printing technologies have received a lot of attentions because of the high flexibility of the process as well as the capability of producing complex shaped and high detailed artifacts with ease. This study focuses on the development of acrylonitrile butadiene styrene (ABS)/graphene composite materials, which can be used as a filament for the melt extrusion 3D printing or FDM 3D printing technique. Since the dispersity of graphene in the polymer matrix is the key parameter of controlling the properties of the composites, the ABS/graphene masterbatches with high concentration of graphene were produced via three techniques: dry mixing; solvent mixing and coagulation techniques. The obtained high concentration ABS/graphene masterbatches were then mixed with pure ABS and melt extruded to produce ABS/graphene composites filament with 1 wt% of graphene. The ABS/graphene composites preparing via solvent mixing and coagulation were found successfully 3D printed. The dry mixing method brought about the aggregation of graphene particle and failed the print.
Preparation of polypyrrole coated zinc anode electrode for inhibition corrosion of secondary zinc ion batteryNuanwat, W; Pattananuwat, P

In this work, polypyrrole coated onto zinc surface anode electrode was successfully prepared via cyclic voltammetry deposition. The different PPy thickness layer on zinc electrode is controlled by the different numbers of deposited cycles at 3, 5, 7 and 10 cycles. The surface morphology development of polypyrrole nano/micro structure covering on zinc surface was examined by Scanning Electron Microscopy-Energy Dispersive X-Ray Spectroscopy. The electrochemical activity of polypyrrole coated zinc electrode is characterized by linear polarization, cyclic voltammetry and galvanic static charge-discharge, indicating that the anti-corrosion PPy surface covering on Zn electrode can yield the highest value of corrosion inhibition efficiency of 67% and serve as high redox layer to improve the charge performance.

This research aimed to enhance properties of fly ash based geopolymer through usage of three types of rice husk ash (RHA). The replacement in the content of 0%, 3%, 5% and 10% by weight was chosen. The RHA used in this study were obtained from (i) the rice drying-process (ii), (iii) in house by burning RH at 600°C and 700 °C. Liquid sodium silicate (LSS) and sodium hydroxide (SH) solution were used as activating agents. The weight ratio of LSS to SH was 1.0 and total liquid to solid was 0.6. The geopolymer prepared without RHA (the control) gave an average compressive strength of 35.91±3.30 MPa. All types of RHA replacement at 3% resulted in an improvement of compressive strength. Further increasing RHA content resulted in an adverse effect on workability and compressive strength of the final products. The highest compressive strength value of 42.52±4.86 MPa was obtained at 3% replacement using RHA burnt at 700 °C. The density results showed a decreased when incorporation of high content of RHA was beyond 5%.

PLA and PBS have more attention from many industries including textiles industry because there are biopolymer, which have eco-friendly. This research aims at fabricating biodegradable fibers from poly (lactic acid) (PLA) blended with poly (butylene succinate) (PBS). PLA and PBS were blended in a twin-screw extruder at various PBS contents 0 to 20 wt%. The blended fibers were then prepared by the melt spinning using a multifilament spinneret. The mechanical, thermal, and morphological properties were characterized by tensile testing, differential scanning calorimetry, and scanning electron microscopy. The results indicate that, at PBS content in PLA of 10 wt%, the obtained fiber has the optimal tensile properties. At this ratio, the blends also possesses the highest crystallinity among the blended fibers. Although these two biodegradable polymers are immiscible, but at the optimal ratio the PBS phase is well-dispersed in the PLA matrix phase.

In this work, we report a novel concept of photo-assisted charging supercapacitive electrode of bismuth ferrite (BFO). The thin film layer of bismuth ferrite electrode is synthesized by electrodeposition technique. The effect of bismuth (III) nitrate/iron (III) nitrate ratio on the capacitive behavior of BFO electrode is investigated. FE-SEM demonstrates the morphology development of flake nanostructure of BFO at the equivalent ratio. The photo-supercapacitive electrode can deliver the highest specific capacitance of 220.50 F g−1 at 10 mV sec−1 under LED light irradiation which is higher than that obtained from dark conditions. This photo active layer can integrate function with the capacitive layer inducing photo-charging mechanism, thus it has great potential of this material electrode for photo-assisted charging supercapacitors application.

A non-covalent nanohybrid of Ferrocene (Fc) with grapheme (Gr) via π-π interaction was proposed for amaranth detection. The synthesized Fc-Gr composite was modified on glassy carbon electrode (GCE) and characterized by cyclic voltammetry (CV) as well as differential pulse voltammetry (DPV). Cyclic voltammogram and differential pulse voltammogram demonstrated successful fabrication of Fc-Gr composite-modified GCE for amaranth detection. DPV was used to obtain a linear range of amaranth detection. The linear range of amaranth detection with a modified sensor was expressed from 10 to 250 μM of amaranth. The limit of detection was obtained at 155 nM of amaranth. Based on these results, the developed sensor provides a good alternative for the determination of amaranth. Moreover, the developed sensor can hopefully be utilized and adapted for detection of other substances.
