title: Influence of UV stabilizers on photo-degradation of PVC/wood flour and PVC/corncob composites by natural weathering test

description: Long-term exposure to sunlight of wood plastic composites (WPCs) leads to photo-degradation. Therefore, it is essential to develop the durability of products by adding UV stabilizers into WPCs. In this research, polyvinyl chloride (PVC) is a matrix and two types of fillers, which are teak wood and corncob with particle sizes 250-425 µm and a fixed content of 60 phr, were used. UV stabilizers used in this study were two types of commercial grade UV absorber. The samples were exposed to sunlight for 4 months. The color change and mechanical properties of samples were determined every week and every month, respectively by natural weathering test method. The results showed that UV stabilizers can delay the lightness change and the color change of PVC but did not significantly affect on PVC/composites. In addition, the lightness of PVC/teak wood flour (PVC/TWF) composites changed more than that of PVC/corncob (PVC/CC) composites after weathering test. Moreover, UV stabilizer can delay the loss in flexural and tensile properties of PVC and PVC composites. The type and loading of UV stabilizer had no significantly affect on the lightness change, flexural and tensile property loss.

title: Industrial ecology approach for biodiesel industry in Thailand

description: Due to the Thai government policy to promote use of biodiesel as an alternative for diesel fuel since 2005, the biodiesel production capacity has been continuously increased. Its production process largely consumes both water and energy and also generates wastes and by-product. The objectives of this research were to study waste management in the biodiesel industry and to propose waste management options based on industrial ecology concept, which includes in-plant clean technology and external waste exchange, in order to improve the environmental performance of the industry. Five biodiesel factories that represented for 1-large, 3-medium, and 1-small scale factory were selected to study their production processes, natural resources consumption, wastes generation, and environmental impacts. The waste management options were proposed and analyzed with respect to technical, economic, and environmental considerations. The results from the survey showed that 1 m3 of biodiesel consumes 900 kg of feeding oil, 160 kg of methanol, 10 kg of catalyst, and 0.47 cb.m. of water. Its production process also generates 140 kg of crude glycerin as by-product, 8 kg of spent bleaching earth, and 0.47 cb.m. of wastewater. The appropriate options are reusing the last methyl ester washing water as the first washing water, purifying crude glycerin as pharmaceutical grade, reusing crude glycerin as raw material of other industries such as biomethanol and propylene glycol, and reusing spent bleaching earth in industrial or agricultural sectors. Generated wastewater can be used to produce biogas which is alternative energy for electricity generation

title: Effect of the crystallite size of nano-titania on the characteristics of LLDPE/titania nanocomposites synthesized by in situ polymerization using metallocene catalyst

description: It is known that the linear low-density polyethylene (LLDPE) can be produced by copolymerization of ethylene and 1-olefins using metallocene catalysts. Metallocene catalyst system can be divided into two systems; homogeneous metallocene catalyst and heterogeneous metallocene catalyst. It was found that homogeneous metallocene catalyst has two major disadvantages; the lack of morphology control of the polymers produced and reactor fouling. Therefore, heterogeneous metallocene catalyst was brought to solve these problems. Polymers filled with inorganic nanoparticles as nanofillers are so-called polymer nanocomposites. It can be produced by the in situ polymerization with the presence of nanofillers added during synthesis by the application of supported metallocene catalysts. In this present study, LLDPE/TiO2 nanocomposites were synthesized by the in situ polymerization with modified methylaluminoxane (MMAO)/zirconocene catalyst. In the first part, the TiO2 nanofillers having different crystallite sizes were employed. The polymerization activities obtained from TiO2 having the highest crystallite size exhibited the highest activity due to its exhibited the weakest interaction. In the second part, the TiO2 nanofillers having different modification with metals were employed. The polymerization activities obtained from unmodified TiO2 exhibited the highest activities due to the unmodified TiO2 had weakest interaction

title: Biogeochemical and physical controls on methane fluxes from two ferruginous meromictic lakes

description: Data was collected at Brownie Lake in Minneapolis, MN, USA and at Canyon Lake in the Upper Peninsula of MI, USA. The methane flux, or the amount of methane entering the atmosphere over a given area per time, was assessed at Brownie Lake and Canyon Lake. Sampling of Brownie Lake during geochemical characterization revealed that the methane flux out of the lake was much higher than Canyon Lake, as well as other ferruginous meromictic lakes used as geochemical analogs for early Earth’s ferruginous oceans. The dataset here was used to discern why the methane flux out of Brownie Lake was high. Brownie Lake was sampled in May, July and September of 2017 and June 2018. Canyon Lake was sampled in June and September 2017 and May 2018. We used various limnological probes and sensors (LDO sensor, Hydrolab multiprobe) to collect water column profiles (temperature, dissolved oxygen, specific conductance, chlorophyll a, pH). We also analyzed water samples (cations, anions, CH4, DIC) using ion chromatography and ICP-MS and measured isotopes (CH4, DIC) utilizing isotope ratio mass spectrometry. The methane flux was constrained in two ways: taking direct samples from the surface of each lake using floating static flux chambers, which were measured by gas chromatography, and estimated from geochemical reaction-transport modeling based on the diffusional profiles of methane and other dissolved species throughout the water column.

title: resilience,CIRR,SBV,depression

description: Studies have documented that school bullying victimization (SBV) aroused by negative interpersonal relationships can lead victims to show more depressive symptoms than those who are not bullied, but few studies have explored the relationship among the three variables from a cumulative interpersonal relationship risk (CIRR) perspective and examined how to reduce the negative chain reactions aroused by CIRR from a positive psychological perspective. The present research explored the protective mechanisms of resilience in the relations among CIRR, SBV and depression and tested 2 serial mediation models for the relationships. Self-report data were collected from 742 middle school students (48.38% male) in grades 7-11 (mean age = 14.32 years, SD =1.54 years). The results supported both models. CIRR could increase SBV by decreasing resilience and, therefore, improve a victim’s depressive level. Alternatively, CIRR could also directly increase SBV and further improve depressive level by decreasing resilience. Our results shed light on the idea that it is a good suggestion to decrease SBV and depression that follow multiple interpersonal relationship risk exposures by cultivating adolescence resilience if we cannot reach the goal by decreasing multiple interpersonal relationship risk at the same time.

title: Parkes observations for project P958 semester 2019APRS_84

description: Fast radio bursts (FRBs) continue to raise more questions than they answer. Until a few months ago, only one burst – the only one known to repeat - had been localized to a bright radio nebula (either a young supernova remnant or pulsar wind nebulae) in a distant dwarf galaxy. Over the last year searches with the Australian Square Kilometre Array Pathfinder (ASKAP) have detected 28 bursts, two of which have been localised to host galaxies at redshifts &gt; 0.3. These bursts and their hosts are very unlike the repeater, suggesting there may be a dichotomy in the population. Over the next six months we expect to detect another 12 FRBs, which will also have sub-arcsecond localisations. Here we propose to search this population for repeats. Our comprehensive sample and a dense monitoring campaign of well localised bursts, at a fluence limit more than 60 times lower than that of their detections, will either confirm the presence of additional repeating FRBs or the uniqueness of FRB 121102 amongst the population.

title: Design of energy integrated and control structures of acetone plant

description: At present, the chemical processes have very complex owsheet with recycle stream, energy integration and different unit operations. Generally, a chemical plant consists of reaction sections and separation section. Both sections need to control system for the safety and economical in plant. This work presents the new heat exchanger 3 networks and 3 alternatives of control structure for acetone plant. Heat exchanger network (HEN) are modified in traditional process for energy saving. The plantwide control structures are designed by using the disturbance load propagation method (Wongsri, M., 1990) and heat pathway heuristics (Wongsri, M. and Hermawan Y.D., 2005) to achieve dynamic maximum energy recovery (DMER). In this work, HYSYS is evaluated performances of the heat exchanger networks and control structures. The result shows that alternative 2 can save energy 81.49% and CS2 is the best control structure for controlling disturbance

title: Improvement of catalytic performance of Pd/α-Al₂O₃ in selective acetylene hydrogenation using mixed phases and nanocrystalline α-Al₂O₃

description: The performance in selective acetylene hydrogenation over Pd/α-Al₂O₃ catalysts has been improved using mixed phases and nanocrystalline α-Al₂O₃. The use of mixed phases Al₂O₃ with approximately 64% of α-phase resulted in significant improvement for both acetylene conversion and ethylene selectivity. The presence of small amount of transition-phase in the alumina supports brought about higher BET surface area and Pd dispersion as well as improvement of reduction ability of the Pd/Al₂O₃ catalysts. On the other hand, significant amount of α-Al₂O₃ is necessary for high ethylene selectivity due to the lower amount of ethylene adsorbed. The improvement of ethylene selectivity can also obtained after reduction at 500°C on the solvothermal-derived nanocrystalline α-Al₂O₃ supported Pd. Moreover, the nanocrystalline α-Al₂O₃ powder with average crystallite size 34-68 nm have been synthesized by three different methods, namely, solvothermal, sol-gel, and precipitation. Nanocrystalline porosity of α-Al₂O₃ powder was varied by changing the preparation methods. Although smallest crystallite size of α-Al₂O₃ was obtained via the sol-gel synthesis, the α-Al₂O₃ sol-gel possessed the least amount of specific surface area and pore volume. A narrow pore size distribution with average pore diameter 15 nm can be obtained via solvothermal method while precipitation method yielded α-Al₂O₃ with larger pore size and wider pore size distribution. When employed as a support for Pd catalysts, the α-Al₂O₃ solvothermal provided the highest Pd dispersion and the best catalyst performance for selective hydrogenation of acetylene. The catalytic properties of Pd/α-Al₂O₃ solvothermal were improved in terms of both acetylene conversion and ethylene selectivity. As shown by temperature program studies, the use of solvothermal-derived α-Al₂O₃ facilitated H2 reduction at low temperature and desorption of ethylene and CO

title: Admicelles and adsolubilization using linker molecules and extended surfactants onto aluminum oxide surface

description: Surfactant-modified adsorbents have been widely used for industrial and environmental applications. Surfactant aggregates adsorbed at the solid/liquid interface are capable of solubilizing organic solutes due to the partition of organic solute from the aqueous phase known as adsolubilization. The surfactants used in this study were linker-based surfactant system and extended surfactant which has propylene oxide group of intermediate polarity, inserted between head and tail of the surfactant molecule. The impact of linker-based and extended surfactant properties on admicelle formation and organic solute adsolubilization were evaluated through adsorption and adsolubilization and solubilization studies on positively charged aluminum oxide surface. While linker-based systems achieved a higher maximum adsorption than extended surfactants, the extended surfactants reached maximum adsorption at a lower aqueous surfactant concentration. The three organic solutes with varying the degree of polarity from high to low value including phenylethanol, styrene, and ethylcyclohexane were evaluated in solubilization and adsolubilization studies. The results are summarized by the extent of solute solubilization into micelle and admicelle, as captured through micellar partition coefficient, (Kmic) and admicellar partition coefficient (Kadm). The extended-surfactant-based micelle and admicelle system showed greater solubilization capacity than the linker-based system. For the high polarity solute (phenylethanol), the presence of propylene oxide group (PO) has a greater effect than the number of PO groups or the tail length, while for the low polarity solute (ethylcyclohexane) as the number of POs groups and the tail length increased, the adsolubilization capacity also increased. These results thus provide insights into linker-based and extended-surfactant-based admicellar systems and highlight the differences observed from admicelles based on conventional surfactant system. The comparison of adsolubilization capacity (Kadm) was lower than solubilization capacity (Kmic) due to the tighter packing density observed in the surface admicelles may have squeezed out the area where enhanced solubilization was experienced in micelles. The extended-based surfactant system demonstrated solubilization and adsolubilization enhancement and significantly lower desorption potential compared to the linker-based surfactant and conventional surfactant system. Thus, the surface modification by extended surfactants shows particular promise for treatment of groundwater and wastewater contaminated with organic solutes

title: Synthesis of 6-hydroxy-2,3,9-trimethoxy-[1]-benzopyrano [3,4-b] [1] benzopyran-12(6H)-one

description: The total synthesis of dehydrorotenoid (1), was successfully achieved in three steps through an intramolecular aldol reaction of the corresponding 1,2-diaryl diketone (19) as a key intermediate. The corresponding 1,2-diaryl diketone was easily accessed via the ruthenium-catalyzed oxidation of diarylacetylene which was obtained from Sonogashira coupling between monoaryl substituted acetylene and aryl iodide. Treatment of 1,2-diaryl diketone with L-proline induced a selective intramolecular aldol reaction, forming the desired benzopyranone without a byproduct benzofuran. Finally, the target dehydrorotenoid was accomplished in 45% overall yield by deprotection and dehydration reactions, respectively. The synthesized dehydrorotenoid (1) and intermediate compounds were evaluated for their biological activities. The results illustrate that compound 1 is inactive, while compound 154 shows activity inhibition of NCI-H187, KB and MCF7 cancer cell lines. However this compound is toxicant to normal cells. Moreover, compound 169, 176a, 176d, 177b, and 177e have been found to potently inhibit the SW620, BT474, KATO-III, Hep-G2, CHAGA, and CH-LIVER cancer cell lines. Even the synthesized dehydrorotenoid (1), target molecule, does not show the expected biological activity but this synthetic methodology provides a very useful procedure for synthesis of the most isoflavanoid, rotenoid and dehydrorotenoid core structure. Therefore, this methodology is valuable for the further study of structure-activity relationship
