Carbon nanotubes growth from camphoric carbon sources using transition metal catalysts / Azira Abd Aziz
No full textThis thesis covers the analysis of catalytic growth of
carbon nanotubes (CNTs) under well-defined conditions,
the optimization of the catalyst and introduces model
for the growth mechanism based on the experimental
results. Experimental investigations are presented to
obtain a comprehensive picture on the catalytic growth
of CNTs. The overall aim of this thesis is to deposit CNTs
by the seeded catalyst method and the modified fluidized
floating catalyst method by Chemical Vapour Deposition
(CVD) and to investigate the effects of starting material
and catalysts on the morphology and structure of the
deposited CNTs. Camphor (C10H16O, crystalline state) and
camphor oil (liquid state) are the precursor materials used
as the source of CNTs. Transition metal (Fe, Ni, Co, Mn,
Al, Mg) catalysts were prepared and the effect on their
catalytic behavior were studied. Metal catalysts have
been prepared by sol-gel method with or without support
catalyst. Correlation between the catalyst particle size
and CNT diameter has been the motivation to reduce the
catalyst particle size down to nanoparticle size
Determinants of saving behaviour among employees in Kelantan / Nor Azira Abd Aziz
No full textThis paper investigates the relationship of income level, credit availability and interest rate effects saving behavior among employee. The target population of this study was employees in area of Kota Bharu, Kelantan and use primary data (questionnaire) as data collection method. A convenience sampling technique use to target 75 respondents. The research design use in this is hypothesis
testing framework. There are three independent variables (income level, interest rate and credit availability) use to test either it have significant to the dependent variable (saving). For data analysis, the finding shows that income level and interest rate has significant relationship with saving behavior. Meanwhile, credit availability not has significant relationship with saving behavio
Reinforcement of multiwalled carbon nanotubes/natural rubber nanocomposite prepared by latex technology
No full textReinforcement of natural rubber was achieved using multiwalled carbon nanotubes (MWCNTs) dispersed with non-ionic, polymeric-based surfactant. MWCNTs were first dispersed in aqueous solution of INUTEC driven by sonication and then mixed with natural rubber latex. From these mixtures MWCNTs with natural rubber were prepared by casting method. The morphology of the reinforced latex films was investigated by FESEM and AFM. When applying adequate preparation conditions, MWCNTs were well dispersed and homogeneously incorporated in the natural rubber matrix. Mechanical and electrical test results showed an increase in the tensile strength and conductivity than to pure natural rubber. The nanocomposites possess the good tensile strength even without extensive purification on the nanomaterials produced and without any pretreatment on the natural rubber used. The approach presented can be adapted to other MWCNTs/polymer latex systems
Dibenzyl ferrocene-1,1′-dicarboxylate
No full textIn the title compound, [Fe(C13H11O2)2], there are markedly different orientations of the two phenylmethoxycarbonyl substituents [O—C—C—C torsion angles = 84.5 (3) and 139.6 (2)°]. These orientations are mediated by a number of intermolecular C—H...O interactions, which result in a one-dimensional hydrogen-bonded network of molecules
Direct accounting system: improving data capture system for timely annual public accounts / Wan Azmin Wan Abd. Aziz
No full textEversince i am aware of the need of proper public accounting system for public monies, I wished I had an indepth knowledge and a reference material from which I could very quickly obtain accurate and concise information regarding the tedious preparation of Annual Public Accounts of the Malaysian Government. I have no doubt that many Malaysians have experienced this need. It is obvious that the Annual Account itself communicates no messages especially to those who have not had the advantage of learning this highly specialised field previously and practical working experience. It is my hope that this research! paper will make my dream comes true and also assist those readers who were curious enough to know the system adopted by the Government in improving data capture for preparation of Annual Public Accounts. I must concede and stress that this is, in essence, only a project paper and to those who demand a detailed exposition of the finer points of the system, may I humbly suggest that they refer to more advanced works by more eminent and di st i ngui shed author s/r esear c hers. However, I am confident that the areas covered ar& comprehensive enough to aid fellow students in their studies in this particular topic
Intercalation and Adsorption of Organic Dyes on Layered Double Hydroxides
No full textNanostructured material of layered organic-inorganic hybrid nanocomposites can be
generated by encapsulation of an organic moiety into an inorganic lamellar in which
the open lamellar systems such as layered double hydroxides (LDHs) can be used as
the host for this study, synthesis of nanocomposite materials was carried out by
using Mg/Al LDH as a host of inorganic layers and naphthol blue black (NEB), fast
green (FG) and methyl orange (MO), organic dyes, as a guest It was found that the
concentrations of the organic moiety and pH are critical for the formation of the well-ordered
nanolayered hybrid materials The optimum concentration of NBB at 1 50 x
10-³ M, FG of 250 x 10⁻² M and 300 x 10² M of MO at pH 10 resulted a well-ordered
nanolayered organic-inorganic hybrid nanocomposites FTIR spectrum of
each nanocomposites resembled a mixture of each spectrum of the organic and
inorganic species, indicating the presence of both in the resulting materials Surface
morphology of Mg/AI-LDH and its nanocomposites show agglomerates of compact and non-porous structure, a typical surface morphology for LDH and Its
nanocomposites
Adapting authoritarianism: institutions and co-optation in Egypt and Syria
No full textThis PhD thesis compares Egypt and Syria’s authoritarian political systems. While the tendency in social science political research treats Egypt and Syria as similarly authoritarian, this research emphasizes differences between the two systems with special reference to institutions and co-optation. Rather than reducibly understanding Egypt and Syria as sharing similar histories, institutional arrangements, or ascribing to the oft-repeated convention that “Syria is Egypt but 10 years behind,” this thesis focuses on how events and individual histories shaped each states current institutional strengthens and weaknesses. Specifically, it explains the how varying institutional politicization or de-politicization affects each state’s capabilities for co-opting elite and non-elite individuals.
Beginning with a theoretical framework that considers the limited utility of democratization and transition theoretical approaches, the work underscores the persistence and durability of authoritarianism. Chapter two details the politicized institutional divergence between Egypt and Syria that began in the 1970s. Chapter three and four examines how institutional politicization or de-politicization affects elite and non-elite individual co-optation in Egypt and Syria. Chapter five discusses the study’s general conclusions and theoretical implications.
This thesis’s argument is that Egypt and Syria co-opt elites and non-elites differently because of the varying degrees of institutional politicization in each governance system. Rather than view one country as more politically developed than the other, this work argues that Syria’s political institutions are more politicized than their Egyptian counterparts. Syria’s political arena is, thus, described as politicized-patrimonialism. Syria’s politicized-patrimonial arena produces uneven co-optation of elites and non-elites as they are diffused through competing institutions. Conversely, the Egyptian political arena remains highly personalized as weak institutions and individuals are manipulated and molded according to the president’s ruling clique. This is referred to as personalized-patrimonialism. As a consequence, Egypt’s political establishment demonstrates more flexibility in ad hoc altering and adapting its arena depending on the emergence of crises.
This study’s theoretical implications suggest that, contrary to modernization and democratization theory’s adage that institutions lead to a political development, politicized institutions within a patrimonial order actually hinder regime adaptation because consensus is harder to achieve and maintain. It is within this context that Egypt’s de-politicized institutional framework advantages its top political elite. In this reading of Egyptian and Syrian politics, Egypt’s personalized political arena is more adaptable than Syria’s. These conclusions do not indicate that political reform is a process underway in either state
