title: Controlled synthesises of ZnO nanoparticles using gas phase reaction

description: Today, research and development on synthesis of nanoparticles becomes of interest global because of their excellent properties in catalytic, optical and magnetic functionality. Zinc Oxide (ZnO) is one of the most promising materials due to its attractive optical function based on a wide band gap of 3.37 eV. ZnO could be synthesized by various methods. Gas phase reaction route is one of potential means being utilized, providing higher purity with low operating cost and applicable at the industrial scale. In this research, the effects of synthesizing parameters on the size and the shape of ZnO nanoparticles were experimentally investigated. These parameters include evaporation temperature, oxidation temperature and gas flow rate. From the experimental results, it could be clearly observed that size and morphology of the ZnO nanoparticles are strongly dependent upon mixing ratio of zinc vapor and oxygen gas. ZnO nanoparticles were changed from a spherical shape to a tetrapod shape when the evaporation and oxidation temperatures were increased. In addition, the interaction between zinc vapor and oxygen was numerically verified by computational fluid dynamic (CFD) technique. FLUENT® was employed for calculating the concentration of zinc vapor and oxygen inside the reactor. In comparison with the experimental results, the use of a gas mixing apparatus (orifice) enhanced the interaction between zinc vapor and oxygen, resulting in uniform size and shape of ZnO nanoparticles.

title: Relationship between interpersonal problem areas and depressive disorders in Thai depressed patients : a matched case-control study

description: Objectives: To identify the interpersonal problem areas related to depressive disorders in Thai depressed patients. Four interpersonal problem areas include grief, interpersonal role disputes, role transitions, and interpersonal deficits. Setting: King Chulalongkorn Memorial Hospital Design: Analytic, matched case-control study 1:1 Subjects and method: The 90 pairs (matched by gender and age) of the depressed and the non-depressed subjects, age above 18 years old, from the Department of Psychiatry, King Chulalongkorn Memorial Hospital, were recruited into the study during July – December 2007. The inclusion criteria for the depressed subjects were new cases of depression (within 6 months) and scores of at least 8 points of Thai Hamilton Rating Scale for Depression (Thai HRSD); the non-depressed subjects: the scores of less than 8 points of Thai HRSD. All subjects completed two questionnaires; 1) Demographic data form, and 2) Thai Interpersonal Questionnaire. The association between interpersonal problem areas and depressive disorders were analyzed by McNemar’s chi-square test. A p-value of less than 0.05 was considered statistically significant. The strength of association was reported by using odds ratio (OR) with 95% confidence interval (95%CI). Conditional logistic regression was performed to identify the predictors of depressive disorders. Results: Most of subjects were young and middle-aged female, living in Bangkok and central region. All four interpersonal problem areas were associated with depressive disorders (p&lt;0.01) in the following strength of association: grief (OR = 7.25, 95%CI = 2.55-28.38), interpersonal role disputes (OR = 4.30, 95%CI = 2.13-9.60), role transitions (OR = 15.00, 95%CI = 5.56-56.84), and interpersonal deficits (OR = 9.00, 95%CI = 3.58-29.05). All four interpersonal problem areas were predictors of depressive disorders in Thai depressed patients (p&lt;0.05). Conclusion: All four interpersonal problem areas were associated with depressive disorders in Thai depressed patients.

title: Altering substrate specificity of alpha-amylase by bioimprinting with beta-cyclodextrin

description: The aim of this study was to alter the substrate specificity of ∞-amylase by the combination of bioimprinting with ®-cyclodextrin (®-CD) and immobilization method. ∞-Amylase was first derivatized with itaconic anhydride to have enough attachment points for enzyme crosslinking. It was determined that the optimum ratio (w/w) of protein to itaconic anhydride was 1:5 which resulted in derivatization degree of 60.7% and the remaining activity of the derivatized enzyme was 93%. The derivatized ∞-amylase was then bioimprinted with ®-CD and immobilized using ethylene glycol dimethacrylate (EGDMA) and 2,2’-azobis (2-methylpropionitrile) (AIBN). It was found that the optimal condition for bioimprinting process was to incubate 30 mg/ml of ∞-amylase with 25 mg/ml of ®-CD in 50 mM sodium acetate buffer pH 6.0 for 30 minutes. And the optimal condition for crosslinking procedure was to use 10 mg/ml of ∞-amylase suspended in cyclohexane with the addition of 4 mg/ml AIBN and EGDMA at the final concentration of 0.82 M under UV irradiation ([gamma] = 240 nm) for 3 hours. The CDase, cyclization and dextrinizing activity of crosslinked imprinted protein (CLIP-∞-amylase) were investigated. The results obtained suggested that the CDase and cyclization activity of CLIP-∞-amylase could not be generated by imprinting with ®-CD under the investigated conditions. Nevertheless, the dextrinizing activity of CLIP-∞-amylase could be altered. The dextrinizing activity was found to be only 42.4% in comparison with that of the crosslinked form where the enzyme was crosslinked without the imprinted molecule.

title: Nanoparticles from cinnamate chitosan derivatives

description: Various chitosan derivatives were prepared by grafting of phthalimido and cinnamoyl groups onto the chitosan chain. Cinnamoyl derivatives used included cinnamic acid, 4-methoxycinnamic acid and 2,4,5-trimethoxycinnamic acid. The obtained cinnamoylphthaloylchitosan, 4-methoxycinnamoylphthaloylchitosan and 2,4,5-trimethoxycinnamoylphthaloylchitosan were induced into nanoparticles by dialysis method using DMF as solvent and water as an antisolvent. The sizes of most cinnamoylphthaloylchitosan nanoparticles were in the range of 50-150 nm. The shape of all cinnamoylphthaloyl chitosan nanoparticulates (DS of cinnamoyl of 0.01, 0.30 and 0.77) and all 4-methoxy cinnamoylphthaloylchitosan nanoparticulates (DS of 4-methoxycinnamoyl of 0.11, 0.22, 0.25 and 0.91) were spherical. The shape of nanoaprticulates from 2,4,5-trimethoxycinnamoylphthaloylchitosan with DS of 2,4,5-trimethoxycinnamoyl at 0.19 and 0.26 were spherical but with DS of 2,4,5-trimethoxycinnamoyl at 1.67 was rod-like. The particle sizes slightly increased with increasing concentrations and degrees of cinnamoyl substitution. The factors influencing the formation, size and shape of these nanoparticles are probably the relative ratio of the hydrophobic to hydrophilic (degree of substitution) segments, chemical structure of cinnamoyl moieties and the concentration to prepare nanoparticulates.

title: Development of wood-substituted composites from highly filled systems of polypropylene and Hevea brasilliensis woodflour

description: In recent years, the natural fibers as reinforcement have been increasingly used to replace the conventional inorganic filler in polymer matrix composites. Especially, natural filler reinforced thermoplastics have a good potential in the future as a substitution for wood-based material in many applications. Natural fibers render several advantages, i.e. the filler cost is usually very low. Also, the natural fillers are biodegradable (thus contributing to an improved environmental impact). In addition, this kind of filler is naturally renewable as well. Moreover, many mechanical and thermal properties can be enhanced. In this work, Hevea Brasiliensis woodflour filled polypropylene composites were prepared by twin screw extruder followed by injection molding. In the first part of this study, the aims are to determine the effect of polypropylene types (PP-HP644T, PP-HP648N and PP-HP740H), average particle sizes, filler contents and sized distributions on the mechanical, thermal and some related physical properties. The experimental results revealed that the composites based on high melt flow rate polymer matrix (PP-HP644T) had higher mechanical properties than those of wood flour composites with PP-HP648N and PP-HP740H. For the effect of particle sizes, filler contents and sizes distributions, it was found that the particle sizes and woodflour contents played a significant role in the mechanical properties of wood flour composites. Flexural and tensile modulus increased, while flexural and tensile strength decreased with increasing woodflour contents. Furthermore, the average particle size of woodflour that was suitable for improving the mechanical properties of the composite was about 200-300 µm. The appropriate bimodal particle sizes that rendered the greatest packing density of wood flour were 275 µm and 49 µm at a mass ratio of 73:27. Additionally, it was found that the thermal stability and degradation temperature (at 5% weight loss) of wood flour composites decreased with increasing woodflour mass fraction. In the second part, maleic anhydride grafted polypropylene (MAPP) was used as a coupling agent to improve the interfacial bond strength between woodflour filler and polymer matrix. The influence of the amount of MAPP on mechanical and thermal properties of woodflour composites has been investigated. This work recommends MAPP content of 5 wt% (of woodflour) to be introduced into the woodflour composites for optimization of the composite mechanical properties. It was reported that the flexural and tensile strength were 110% and 87% higher than those of the woodflour composite without MAPP, respectively. The thermal stability and degradation temperature of woodflour composites containing the coupling agent were slightly increased with increasing coupling agent content.

title: Transformation of epoxides into halohydrins and aminoalcohols by metal halides

description: This work focuses on the development of an efficient procedure for the selective ring opening of substituted epoxides under mild and rapid conditions utilized either chromium(III) chloride or chromium(III) nitrate. The ring opening of alkyl- and aryl-substituted epoxides with these chromium(III) reagents produced halohydrin and aminoalcohol in high to excellent yield. Regioselectivity for a C-O bond cleavage of epoxide via Lewis acid promoted was greatly depended on the substitution pattern of epoxides furnished halohydrins and aminoalcohols through a predominantly SN2-type mechanism. This procedure is very simple, mild, rapid, commercially available, inexpensive, insensitive to air and high selectivity of product compared to those catalyzed by other Lewis acids.

title: Algorithm development for optimal cleaning of heat exchanger network using time discretisation approach

description: In all chemical plants using heat exchangers, fouling of heat transfer surfaces is a major problem because it increase energy consumption resulting in economic losses. Thus, the regular cleaning of fouled units is implemented to reduce this losses. In this work, the simulations of heat exchanger in a case of single unit and also in network are performed based on linear and asymptotic fouling models. The effect of various model parameters on a variations with time of outlet temperature of hot and cold stream, heat transfer coefficient and heat transfer rate is investigated. In addition, the problem of optimal cleaning schedule of heat exchangers based on time discretisation approach is formulated. The formulated optimization problem minimizes the summation of operating cost with subject to various operating conditions constraints. The optimized variables are logical variables decided whether a heat exchanger should be cleaned in each time period specified. Moreover, we also develop a new technique to handle a very large number of logical variables occurred in the problem formulated. Our technique can efficiently solve the problem while obtain a better solution compared with the traditional method.

title: DSCR1 gene silencing by siRNA in lymphoblast cells from patient with down syndrome

description: DSCR1 (Down Syndrome Critical Region 1) gene directly affect to the learning and memory process in human expecially in fetal Down Syndrome (DS) brain. DSCR1 belongs to a highly conserved calcineurin inhibitor family called calcipressin. DSCR1 can bind to and inhibit calcineurin, a protein important for learning and memory. RNAi technique which is a naturally occurring cellular mechanism that induces post transcriptional gene silencing .Small interfering RNA (siRNA) molecules are the key intermediaries in post transcriptional gene silencing which when exogenously administered can inhibit the expression of any given target gene. Since DSCR1 is overexpressed in DS fetal brain, it is possible that normalizing DSCR1 expression may restore normal brain function in DS individual. The goal of this study is to inhibit DSCR1 gene in lymphoblast cells by siRNA. In this research we studied DSCR1 gene expression level in both mRNA and protein by real time PCR and western blot consequently.The comparison result of mRNA level between untreated and treated with 3 concentrations of siRNAs ( 0.4 ,0.8 and 1 μg) in control and case samples indicated that siRNAs did not affect to mRNA level of DSCR1 gene in both of samples at 14th day (Pr=0.7878, 0.7099 and 0.4103) From above result it might be the long period of post-transfection. The DsRed2 gene was cloned into siRNA plasmid vector to indicate the transfection efficiency. RFP signal was shown that siRNAs were effectively within 8 days of post transfection .From this result , I decide to make an additional experiment by decrease time period and sample quantity, harvest lymphoblast cell lines 5 samples from normal and measure mRNA at 5th day of post-transfection at appropriate siRNA concentration (0.8 μg) for test DSCR1 suppression . After changing the time, I found siRNA cannot knockdown DSCR1 gene (t test, Pr=0.3431), Moreover we tested transfection efficiency in both of fibroblast and lymphoblast cells from same case sample. We demonstrate that the percentage of transfection efficiency and period of signal in both of cell types are not different .

title: Development of amperometric immunosensor using boron-doped diamond with poly (o-amiobenzoic acid)

description: This thesis studied the electrochemical properties of the products of seven substrates for the enzyme label, alkaline phosphatase, which is commonly used in electrochemical immunosensors. Cyclic voltammetry and amperometry of these products were carried out at glassy carbon disk, gold disk, and screen-printed carbon electrodes. Among the products, L-ascorbic acid showed the most sensitive and well-defined amperometric response, obtaining from 2-phospho-L-ascorbic acid substrate for the electrochemical detection with an alkaline phosphatase label. Using MIgG as a model analyte, the alkaline phosphatase-amplified sandwich-type amperometric immunosensor was constructed. The immunosensor was fabricated by electropolymerization of o-aminobenzoic acid (o-ABA) on the electrode surfaces. Covalently immobilized onto the poly-o-ABA modified electrodes, the anti-MIgG was bound with the target MIgG that was caught with the alkaline phosphatase conjugated anti-MIgG to form a sandwich-type immunosensor. The alkaline phosphatase is capable of changing 2-phospho-L-ascorbic acid to electroactive L-ascorbic acid, which can be determined by the amperometric detection with the signal directly proportional to the quantity of MIgG. The best performance for the poly-o-ABA modified Au disk immunosensor was 297-to-1 current density response ratio for 1000 and 0 ng mL¯¹ MIgG and detected MIgG down to the concentration of 1 ng mL¯¹ with the linear range of 3-200 ng mL¯¹. Boron-doped diamond, the new electrode material was developed for the MIgG immunosensor. The poly-o-ABA modified boron-doped diamond was characterized by scanning electron microscopy and X-ray photoelectron spectroscopy. X-ray photoelectron spectroscopic results revealed the presence of carboxyl groups at the modified electrode surface. These carboxyl groups were used to covalently attach to the anti-MIgG. The amperometric sensing of MIgG from poly-o-ABA modified glassy carbon plate immunosensor was compared. The LODs of 0.30 and 3.50 ng mL¯¹for MIgG at boron-doped diamond and glassy carbon plate electrodes were obtained. Three orders of magnitude of the wide linear range (1-1000 ng mL¯¹) was obtained from the boron-doped diamond whereas the narrower linear range (10-500 ng mL¯¹) was found at the glassy carbon plate. In addition, the proposed method was successfully applied to a real mouse serum sample containing MIgG.
