Abstract:
Preparation of functionalized graphene by electrochemical exfoliation of graphite rod using sodium dodecyl benzene sulfonate (SDBS) is reported. SDBS solution has been used as the electrolyte as well as functional groups. SDBD is an anionic surfactant which helps to provide uniform dispersion in water and prevents the π-π π-π stacking as well. XRD result indicates the formation of graphene whereas; the functionalization of graphene was confirmed through the FT-IR spectrum, which shows presence of peaks corresponding to SO3-. UV-vis spectroscopy demonstrates the dispersibility of SDBS-functionalized graphene, and peaks of SDBS and graphene appeared at 225 nm and 260nm, respectively. Raman spectroscopy show ID/IGIDIG ratio is < 1. It means that defects of SDBS-functionalized graphene are reduced.

Abstract:
Among the surfactants used for removal of radioactive nuclides generated from nuclear decontamination, sodium dodecylbenzenesulfonate (SDBS) is frequently used. A potential environmental problem of incomplete elimination of SDBS from radioactive liquid wastes (RLWs), which contain a high concentration of SDBS and radioactive nuclides, still remains. Removal of SDBS was evaluated by adsorption using commercially available, macroporous polymer-based adsorbents, HP20 and HP2MGL, which are styrene (St)- and methyl methacrylate (MMA)-based crosslinked resin beads, respectively. The effect of the macroporosity and chemical structure of the macroporous adsorbent resins (MARs) on the adsorption behavior was investigated. HP20 did not have any functionality for adsorbing SDBS, but it showed effective adsorption toward SDBS (less than 20 min to reach 90% adsorption), because of the hydrophobic interaction between the phenyl groups in the St unit in HP20 and in the SDBS. The removal of SDBS from a mixed solution of SDBS and Cs ions was investigated to elucidate the adsorption process in an imitation of the sort of RLWs. This investigation suggests that MARs can potentially be used for the removal of SDBS not only from a SDBS solution but also from a mixed solution of SDBS and Cs ions.

Abstract:
The effect of an divalent electrolyte Ca2+ on the flocculation of two different concentrations of anionic surfactant Sodium Dodecylbenzenesulfonate (SDBS) with Al3+ has been investigated at different molar ratios Al3+ to SDBS at 298.15 K. The results showed that the flocculation characteristics of 0.01 mol•L-1 SDBS (above the critical micelle concentration CMC) and 0.001 mol•L-1 SDBS (below the CMC) were obviously different with an increase of dosages of Al3+. The z-average size of flocculate of 0.01 mol•L-1 SDBS with Al3+ decreased particularly with the pre-addition of Ca2+，It suggested the formation of the complexion Ca(SDBS)2. At optimization flocculation areas at 298.15K, pH values were all around 3.5 in the flocculation systems SDBS/Al3+ and Ca2+/SDBS/Al3+ whether the SDBS concentration above or below the CMC. The pre-addition of Ca2+ slightly affected other flocculation parameters of SDBS/Al3+ systems such as zeta potential, surface tension, conductivity and pH.

Abstract:
Four products were obtained from sodium dodecylbenzene sulfonate (SDBS) and formaldehyde (40% solution) using a simple reaction. The products were characterized by TGA, IR, UV and MS to confirm the major chemicals in each sample. The new products could reduce the interfacial tension between oil and water in the experimental temperature range further compared to SDBS. The emulsion ability was also enhanced by SDBS-1 to SDBS-4. The oil-displacement efficiencies of SDBS-1 to SDBS-4 were obviously higher than that of SDBS, and the oil-displacement efficiency of SDBS-2 was the best, with an efficiency of 25%. The experimental results all indicate that these products have an excellent ability to reduce oil–water interfacial tension and that they can be used in the oil and petrochemical industry for oil production and have certain practical uses.

Abstract:
It is of great importance to improve the proton conductivity of proton exchange membranes by easy-handling and cost-efficient approaches. In this work, we incorporated a commercially obtained surfactant, sodium dodecyl benzene sulfonate (SDBS), into sulfonated poly(ether ether ketone) (SPEEK) through solution casting to prepare SPEEK/SDBS membranes. When no more than 10 wt % SDBS was added, the SDBS was well dissolved into the SPEEK matrix, and the activation energy for the proton transfer in the SPEEK/SDBS membranes was greatly reduced, leading to significant enhancement of the membrane proton conductivity. Compared with the SPEEK control membrane, the SPEEK/SDBS membrane with 10 wt % SDBS showed a 78% increase in proton conductivity, up from 0.051 S cm−1 to 0.091 S cm−1, while the water uptake increased from 38% to 62%. Moreover, the SPEEK/SDBS membrane exhibited constant proton conductivity under a long-term water immersion test.

Abstract:
The corrosion behavior of brass in TiO2 and Al2O3 nanofluids using a simulated cooling water (SCW) as the base solution and sodium dodecyl benzene sulfonate (SDBS) as the dispersant was studied by electrochemical measurements and surface analysis in this paper. It was found that SDBS could be adsorbed on the brass surface to form a protective film and have a corrosion inhibition effect on brass in SCW. In the SCW-SDBS-TiO2 nanofluid, some negatively charged TiO2 nanoparticles were attached to the brass surface and no obvious SDBS adsorption film was found, and the SDBS in this nanofluid had almost no corrosion inhibition on brass. In the SCW-SDBS-Al2O3 nanofluid, the brass surface was covered by a uniformly distributed SDBS film containing some Al2O3 nanoparticles which were positively charged, and the corrosion inhibition of brass was significantly improved in this nanofluid. It is concluded that the adsorption of SDBS on the brass surface in nanofluids is related to the charge status of the nanoparticles, which makes brass have different corrosion resistance in various nanofluids.

Abstract:
Method validation of sodium dodecylbenzene sulfonate (SDBS) analysis in catfish by maceration and UV-Vis spectrophotometry using methylene blue active substances (MBAS) method was performed. The first stage of this research was method validation comprising correlation coefficient, sensitivity, Limit of Detection (LOD), Limit of Quantitation (LOQ), precision, and accuracy. The extraction of SDBS by maceration with methanol for 16 h and analysis by UV-Vis spectrophotometry using MBAS were performed. Then, this method was applied to analyze SDBS in catfish. The results of validation of SDBS analysis in cultivated catfish give correlation coefficient 0.9944, sensitivity 10.57 × 104 L mol-1 cm-1, LOD 0.01776 mg/L, LOQ 0.05922 mg/L, precision 0.1351-1.300 %, and accuracy 87.64-90.01 %, respectively. The SDBS concentrations in fish increase with the increase in the SDBS concentration in cultivating water. Bioconcentration Factor (BCF) values were inversely proportional to the concentration of SDBS in the cultivating water. The concentrations of SDBS on catfish, tilapia, and carp in traditional markets were 5.719-8.162; 5.180-6.548; and 2.973-5.874 mg/kg, respectively. In general, analysis method of SDBS in catfish by maceration and UV-Vis spectrophotometry with MBAS show a good result and can be used as a routine analysis in fish.

Abstract:
In order to study the effect of inorganic salt additives on the surface tension of a sodium dodecylbenzene sulfonate (SDBS) solution, the surface tension of the mixed system of six common inorganic salt additives, NaCl, CaCl2, AlCl3, Na2SO4, Na2CO3, and NaHCO3, and SDBS was measured, and the effects of the inorganic salt types, surfactant concentrations and inorganic salt concentrations on the surface tension of the SDBS solution were studied. On this basis, three inorganic salts, NaCl, CaCl2 and Na2SO4, were selected, and their effects on the critical micelle concentration (CMC) of the SDBS solution were studied. The experimental results showed that different inorganic salts had different effects on the surface tension of the SDBS solution. The order of effect of the six inorganic salts on the surface tension of the SDBS solution was CaCl2 > NaCl > Na2SO4 > NaHCO3 > Na2CO3 > AlCl3; when the mass fraction of the SDBS solution is high, the influence of the inorganic salts on the surface tension of the SDBS solution is relatively small; with an increase in the concentration of the preferred inorganic salt additives, the surface tension of the SDBS solution decreases first, then tends to be stable, and then increases; a reduction in the critical micelle concentration by the three selected inorganic salt additives shows the trend of 0.7% NaCl > 0.5% CaCl2 > 0.5% Na2SO4.

Abstract:
AbstractTo enhance the gasoline octane number, low-octane linear n-alkanes should be converted into their high-octane di-branched isomers via n-alkane hydroisomerization. Therefore, hierarchical SAPO-11-based catalysts are prepared by adding different contents of sodium dodecylbenzene sulfonate (SDBS), and they are applied in n-nonane hydroisomerization. When n(SDBS)/n(SiO2) is less than or equal to 0.125, the synthesized hierarchical molecular sieves are all pure SAPO-11, and as the SDBS content increases, the submicron particle size decreases, and the external surface area (ESA) increases. Additionally, these hierarchical SAPO-11 have smaller submicron particles and higher ESA values than conventional SAPO-11. When n(SDBS)/n(SiO2) is greater than 0.125, with increasing SDBS content (n(SDBS)/n(SiO2) = 0.25), the synthesized SAPO-11 contains amorphous materials, which leads to a decline in the ESA; with the further increase in SDBS content (n(SDBS)/n(SiO2) = 0.5), the products are all amorphous materials. These results indicate that in the case of n(SDBS)/n(SiO2) = 0.125, the synthesized SAPO-11 molecular sieve (S–S3) has the most external Brønsted acid centers and the highest ESA of these SAPO-11, and these advantages favor generation of the di-branched isomers in hydrocarbon hydroisomerization. Among these Pt/SAPO-11 catalysts, Pt/S–S3 displays the highest selectivity to entire isomers (83.4%), the highest selectivity to di-branched isomers (28.1%) and the minimum hydrocracking selectivity (15.7%) in n-nonane hydroisomerization.

Abstract:
Porous structure and surface defects are important to improve the performance of supercapacitors. In this study, a facile pathway was developed for high-performance supercapacitors, which can produce transition metal hydroxides (LDHs) with abundant porous structure and surface defects. The NiCo-SDBS-LDH was prepared by one-step hydrothermal reaction using sodium dodecylbenzene sulfonate (SDBS) as anionic surfactant. And then, three dimensional (3D) interconnected porous flower-like 3D-NiCo-SDBS-LDH microspheres were designed and synthesized using the gas-phase hydrazine hydrate reduction method. Results showed that the hydrazine hydrate reduction not only introduces a large number of pores into 3D-NiCo-SDBS-LDH microspheres and causes the formation of oxygen vacancies, but it also roughens the surface of the microspheres. All these changes contribute to the enhancement of electrochemical activity of 3D-NiCo-SDBS-LDH; the NiCo-SDBS-LDH electrode after hydrazine hydrate treatment (3D-NiCo-SDBS-LDH) exhibits a higher specific capacitance of 1148 F·g−1 at 1 A·g−1 (about 1.46 times larger than that of NiCo-SDBS-LDH) and excellent long cycle life with 94% retention after 4000 cycles. Moreover, the assembled 3D-NiCo-SDBS-LDH//AC (active carbon) asymmetric supercapacitor (ASC) achieves remarkable energy density of 73.14 W h·kg−1 at 800 W·kg−1 and long-term cycling stability of 95.5% retention for up to 10,000 cycles. The outstanding electrochemical performance can be attributed to the synergy between the rich porous structure and the roughened surface that has been created by the hydrazine hydrate treatment.

Abstract:
We have investigated single-walled carbon nanotube (SWCNT) networks wrapped with the cationic surfactant sodium dodecyl-benzenesulfonate (SBDS) as promising candidates for water detection. This is the first time that the humidity behavior of endohedral Li-doped (Li@) and undoped SWCNTs/SDBS has been shown. We identified a strong and almost monotonic decrease in resistance as humidity increased from 11 to 97%. Sensitivities varied between −3 and 65% in the entire humidity range. Electrical characterization, Raman spectroscopy, and high-resolution transmission electron microscopy (HRTEM) analysis revealed that a combination of the electron donor behavior of the water molecules with Poole-Frenkel conduction accounted for the resistive humidity response in the Li@SWCNT/SDBS and undoped SWCNT/SDBS networks. We found that Li@SWCNTs boosted the semiconducting character in mixtures of metallic/semiconducting SWCNT beams. Moreover, electrical characterization of the sensor suggested that endohedral Li doping produced SWCNT beams with high concentration of semiconducting tubes. We also investigated how frequency influenced film humidity sensing behavior and how this behavior of SWCNT/SDBS films depended on temperature from 20 to 80 ∘ C. The present results will certainly aid design and optimization of SWCNT films with different dopants for humidity or gas sensing in general.

Abstract:
In this work, we aim to study some fine properties for functional stochastic differential equation. The results consist of five main parts. In the second chapter, by constructing successful couplings, the derivative formula, gradient estimates and Harnack inequalities are established for the semigroup associated with a class of degenerate functional stochastic differential equations. In the third chapter, by using Malliavin calculus, explicit derivative formulae are established for a class of semi-linear functional stochastic partial differential equations with additive or multiplicative noise. As applications, gradient estimates and Harnack inequalities are derived for the semigroup of the associated segment process. In the fourth chapter, we apply the weak convergence approach to establish a large deviation principle for a class of neutral functional stochastic differential equations with jumps. In particular, we discuss the large deviation principle for neutral stochastic differential delay equations which allow the coefficients to be highly nonlinear with respect to the delay argument. In the fifth chapter, we discuss the convergence of Euler-Maruyama scheme for a class of neutral stochastic partial differential equations driven by alpha-stable processes, where the numerical scheme is based on spatial discretization and time discretization. In the last chapter, we discuss (i) the existence and uniqueness of the stationary distribution of explicit Euler-Maruyama scheme both in time and in space for a class of stochastic partial differential equations whenever the stepsize is sufficiently small, and (ii) show that the stationary distribution of the Euler-Maruyama scheme converges weakly to the counterpart of the stochastic partial differential equation.

Abstract:
This thesis is mainly concerned with semantic data modelling related to database design. The domain of this research is restricted to general data modelling and the discussion is carried out at the conceptual level. The thesis assesses a number of serious modelling shortcomings of the conventional data models and reviews several basic principles and mechanisms developed in current semantic data modelling research. Based on these findings, the thesis identifies the inadequacy of the conceptualization of data modelling and develops the two-view conceptualization of data modelling. The basic idea behind the two-view conceptualization is that the conceptual structure of the applications being modelled should be separated from its external data representation. A new semantic database model, SDBM, is designed based on the conceptualization. The model makes a clear separation between the conceptual structure and its external data representation. It offers a data type mechanism to deal with the data representation, a window mechanism to model the conceptual structure, and a transaction mechanism to provide database operations. One of the major extensions of the current semantic data models is that with SDBM the specialization relationship is just a special case of constraints that can be specified among SDBM windows. A formal syntax and informal semantics of SDBM are given in the thesis along with comparisons between SDBM and a closely-related semantic data model, Taxis.<br>Business, Sauder School of<br>Graduate

Abstract:
AbstractA wide range of symbolic analysis and optimization problems can be formalized using polyhedra. Sub-classes of polyhedra, also known as sub-polyhedral domains, are sought for their lower space and time complexity. We introduce the Strided Difference Bound Matrix (SDBM) domain, which represents a sweet spot in the context of optimizing compilers. Its expressiveness and efficient algorithms are particularly well suited to the construction of machine learning compilers. We present decision algorithms, abstract domain operators and computational complexity proofs for SDBM. We also conduct an empirical study with the MLIR compiler framework to validate the domain’s practical applicability. We characterize a sub-class of SDBMs that frequently occurs in practice, and demonstrate even faster algorithms on this sub-class.

Abstract:
Abstract Offshore wind turbines are subjected to harsh marine environment, which can cause detrimental problems to their integrity due to corrosion. Offshore wind energy is considered to play an important role on the net zero emissions by 2050, contributing to environmental protection, hence the long-term protection from corrosion of these offshore structures is of high importance. In this work the formation of microcapsules, loaded with corrosion inhibitor liquid is presented. More specifically the microcapsules consist of polystyrene shell and 3-octanoylthio-1-propyltriethoxysilane core. The formation of the microcapsules was achieved by testing different variables such as four agitation rates and three different emulsifiers. The experiments revealed that the optimum diameter size was achieved in agitation rates between 400 and 500 rpm and with sodium dodecylbenzene sulfonate (SDBS) as emulsifier. Agitation times were also tested. Hence, this work highlights the formation of microcapsules with self-healing properties, which can offer corrosion solution to offshore wind turbines when used as part of a coating system.

Abstract:
In this paper, the influence of sodium dodecylbenzenesulfonate (SDBS) on the dispersive behavior of Al2O3 nanoparticles in water are investigated by measuring zeta potential and hydrodynamic sizes of the nanoparticles in suspension at different pHs and different concentration of SDBS. The experimental results show that at different pHs the magnitude of zeta potential has very homologous relation with particle size, the higher magnitude of zeta potential values are, the smaller of the hydrodynamic sizes are, and the better dispersive stability of the nano-suspension is, and that an optimizing pH value of the nano-suspension can induce the highest magnitude zeta potential, then result in the best dispersion stability of the nano-suspension. It is also found that concentrations of SDBS can significantly affect the values of zeta potential and hydrodynamic sizes of the nanoparticles by electrostatic repulsions. Similarity, optimizing concentrations of SDBS can also lead to the highest enhancement of the dispersive stability of the Al2O3 suspension and the optimizing concentration for SDBS is 0.09% in 0.1% Al2O3 nano-suspensions, which have the best disperse results.

Abstract:
Dispersion and stability of Cu nano-suspensions with dispersant is the important base for the study of rheology and heat transfer enhancement of the suspensions. This paper presented a procedure for preparing a nanofluid which was a suspension consisting of nanophase powders and a base liquids. By means of the procedure, Cu-H2O nanofluids with and without dispersant were prepared, whose sedimentation photographs were given to illustrate the stability and evenness of suspension with dispersant. Dispersion and stability of Cu nanoparticles in water were studied under different pH values and the concentration of sodium dodecylbenzenesulfonate (SDBS) dispersant by the method of zeta potential, absorbency and sedimentation photographs. The results show that zeta potential has very corresponding relation with absorbency, and the higher absolute value of zeta potential and absorbency are, the better dispersion and stability in system is. The absolute value of zeta potential and absorbency are higher at pH 9.5. SDBS can significantly increase the absolute value of the zeta potential of the particle surfaces by electrostatic repulsions, which leads to the enhancement of the stability of the Cu suspensions. The optimizing concentration for SDBS in the 0.1% copper nano-suspensions is 0.07%, which has the best disperse results.

Abstract:
Nanofluids have been attractive for the last few years with the enormous potential to improve the efficiency of heat transfer fluids. This work focuses on the effect of pH and sodium dodecylbenzenesulfonate (SDBS) surfactant on the thermal conductivity of nanofluids.The thermal conductivity was measured by a Hot Disk Thermal Constants Anlyser. The results showed that the thermal conductivity enhancements of Cu–H2O nanofluids are highly dependent on the weight fraction of nanoparticle, pH values and SDBS surfactant concentration of nano-suspensions. The Cu–H2O nanofluids with an ounce of Cu have noticeably higher thermal conductivity than the base fluid without nanoparticles, For Cu nanoparticles at a weight fraction of 0.001 (0.1 wt %), thermal conductivity was enhanced by up to 10.7%, with an optimal pH value and SDBS concentration for the highest thermal conductivity. Therefore, the combined treatment with both the pH and chemical surfactant is recommended to improve the thermal conductivity for practical applications of nanofluid.

Abstract:
Abstract The storage of CO2 foam in saline aquifers is an effective way of CO2 geo-sequestration. However, one of the primary concerns during storage of CO2 in underground geological reservoirs is the rapid upward migration of CO2 plume which eventually challenges the containment security. Injection of foam has been proposed as an effective solution to this problem from decades. Foams have low mobility and prevent the formation of high mobility channels. Surfactant is a crucial component in generating stable aqueous foam. The selection of surfactants as foaming agents is very important for the performance of the foam. The stability of a surfactant generated foam depends on the surfactant type, its concentration, salinity, pressure and temperature. In this study, stability of foam generated with two surfactants sodium dodecylbenzenesulphonate (anionic) and cetyl trimethylammonium bromide (cationic) are investigated at different surfactant concentrations. The effect of salinity and temperature were also investigated. The form was generated by purging air into a brine solution containing the surfactant. The foamability and the stability of the produced foam is first observed under room temperature and are then observed under elevated temperatures. The elevated temperature foam stability is observed by keeping the produced foam in an oven. The foamability was observed to increase with surfactant concentration. The salt inhibits generation of foam and the effect is prominent for CTAB than SDBS. The CTAB assisted foam has a higher stability than SDBS. However, at high temperature the foam stability was found to reduce significantly for both SDBS and CTAB; with CTAB foam has slightly higher stability than SDBS.

Abstract:
Subnational development banks (SDBs) in Latin America and the Caribbean (LAC) provide financing to regional and local governments, subnational entities, and small and medium enterprises (SMEs), but generally lack information about how they can support the transition toward net-zero greenhouse gas emissions and environmental sustainability. This document describes how SDBs can support blended financing arrangements that combine both public and private resources, leveraging their comparative advantage in mitigating the high risks that private lenders perceive of working with actors at the subnational level. The document provides illustrative cases from both regional and international contexts of how public development banks can mobilize private capital for local economic development. It concludes with strategic recommendations for SDBs to increase sustainable financing for a just urban and territorial transition and for the Alliance of Subnational Development Banks in Latin America and the Caribbean as a platform to foster a regional dialogue that can increase financial innovation across the region.
