| 1 | Neural-fuzzy control system application for monitoring process response and control of anaerobic hybrid reactor in wastewater treatment and biogas production显示文摘Based on the developed neural-fuzzy control system for anaerobic hybrid reactor (AHR) in wastewater treatment and biogas production,the neural network with backpropagation algorithm for prediction of the variables pH,alkalinity (Alk) and total volatile acids (TVA) at present day time t was used as input data for the fuzzy logic to calculate the influent feed flow rate that was applied to control and monitor the process response at different operations in the initial,overload influent feeding and the recovery phases.In all three phases,this neural-fuzzy control system showed great potential to control AHR in high stability and performance and quick response.Although in the overloading operation phase II with two fold calculating influent flow rate together with a two fold organic loading rate (OLR),this control system had rapid response and was sensitive to the intended overload.When the influent feeding rate was followed by the calculation of control system in the initial operation phase I and the recovery operation phase III,it was found that the neural-fuzzy control system application was capable of controlling the AHR in a good manner with the pH close to 7,TVA/Alk < 0.4 and COD removal > 80% with biogas and methane yields at 0.45 and 0.30 m3 /kg COD removed. | Chaiwat Waewsak Annop Nopharatana Pawinee Chaiprasert | 2010 | Journal of Environmental Sciences2010，22，12： | 8 |
| 2 | Combination eect of pH and acetate on enzymatic cellulose hydrolysis显示文摘The productivity and eciency of cellulase are significant in cellulose hydrolysis. With the accumulation of volatile fatty acids (VFAs), the pH value in anaerobic digestion system is reduced. Therefore, this study will find out how the pH and the amount of acetate inuence the enzymatic hydrolysis of cellulose. The eects of pH and acetate on cellulase produced from Bacillus coagulans were studied at various pH 5-8, and acetate concentrations (0-60 mmol/L). A batch kinetic model for enzymatic cellulose hydrolysis was constructed from experimental data and performed. The base hypothesis was as follows: the rates of enzymatic cellulose hydrolysis rely on pH and acetate concentration. The results showed that the suitable pH range for cellulase production and cellulose hydrolysis (represents eciency of cellulase) was 2.6-7.5, and 5.3-8.3, respectively. Moreover, acetate in the culture medium had an eect on cellulase production (KI = 49.50 mmol/L, n = 1.7) less than cellulose hydrolysis (KI = 37.85 mmol/L, n = 2.0). The results indicated that both the pH of suspension and acidogenic products inuence the enzymatic hydrolysis of cellulose in an anaerobic environment. To enhance the cellulose hydrolysis rate, the accumulated acetate concentration should be lower than 25 mmol/L, and pH should be maintained at 7. | ROMSAIYUD Angsana SONGKASIRI Warinthorn NOPHARATANA Annop CHAIPRASERT Pawinee | 2009 | Journal of Environmental Sciences2009，21，7： | 8 |

| 13 | Enhancement of output power density in a modified polytetrafluoroethylene surface using a sequential O_(2)/Ar plasma etching for triboelectric nanogenerator applications显示文摘In this work,the surface modification using a two-steps plasma etching has been developed for enhancing energy conversion performance in polytetrafluoroethylene(PTFE)triboelectric nanogenerator(TENG).Enhancing surface area by a powerful O_(2) and Ar bipolar pulse plasma etching without the use of CF_(4) gas has been demonstrated for the first time.TENG with modified surface PTFE using a sequential two-step O_(2)/Ar plasma has a superior power density of 9.9 W·m^(-2),which is almost thirty times higher than that of a pristine PTFE TENG.The synergistic combination of high surface area and charge trapping sites due to chemical bond defects achieved from the use of a sequential O_(2)/Ar plasma gives rise to the intensified triboelectric charge density and the enhancement of power output of PTFE-based TENG.The effects of plasma species and plasma etching sequence on surface morphologies and surface chemical species were investigated by a field emission scanning electron microscopy(FESEM),atomic force microscopy(AFM),and X-ray photoelectron spectroscopy(XPS).The correlation of surface morphology,chemical structure,and TENG performance was elucidated.In addition,the applications of mechanical energy harvesting for lighting,charging capacitors,keyboard sensing and operating a portable calculator were demonstrated. | Teerayut Prada Viyada Harnchana Anthika Lakhonchai Artit Chingsungnoen Phitsanu Poolcharuansin Narong Chanlek Annop Klamchuen Prasit Thongbai Vittaya Amornkitbamrung | 2022 | Nano Research2022，15，1： | 0 |
