description: AbstractMOF-46 and a novel core-shell heterostructure containing ZnO@MOF-46 rods have been successfully synthesized via a simple, versatile and economic method. The products have been characterized by X-ray diffraction (XRD), FTIR spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDX). Time and solvent effects on the growth process of ZnO@MOF-46 were investigated. Luminescent properties of the activated sample showed distinct solvent-dependent photoluminescence emissions. The product also demonstrated unique sensing properties in detection of aromatic compounds via a fluorescence quenching and enhancing mechanism. Aromatic compounds with electron-withdrawing substituents such as nitro act as fluorescence quenchers for ZnO@MOF-46 and aromatic compounds with electron-donating substituents such as CH3 were found to enhance the ZnO@MOF-46 fluorescence. The ZnO@MOF-46 showed excellent photodegradation of methylene blue. The degradation rates in presence of various scavengers including benzoquinone, isopropyl alcohol and ammonium oxalate (O2 •-, OH• and h+ scavengers, respectively) were studied and the results showed all of species (O2 •-, OH• and h+) contribute to degradation but the OH• is the main active species and plays a major role in this system and hence photocatalyst degradation was supposed to have a radical mechanism. Band structure parameters of ZnO@MOF-46 were determined using cyclic voltammetry and DRUV/VIS spectroscopy and the mechanism of photodegradation was then discussed.

The Magnitude-Diameter Relation of Galaxies
Creators: name: Bergh, Sidney van den
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We investigate the dependence of the luminosity-diameter relation of galaxies on the environment. This study is based on a comparison between the 80 galaxies in the Shapley-Ames Catalog that are located within a distance of 10 Mpc, and the luminosity-diameter relation for galaxies in great clusters such as Virgo and Coma. A relatively tight linear correlation is observed between the absolute magnitudes and the logarithms of the linear diameters of galaxies located within 10 Mpc. Surprisingly this observed power-law relationship appears to be almost independent of environment and local mass density as defined by Karachentsev & Malakov. However, at a given luminosity, early-type galaxies are (on average) slightly more compact than are objects of a later type. Unexpectedly the present results appear to indicate that the luminosity-diameter relation for the galaxies within 10 Mpc is indistinguishable from what is observed in the much denser Virgo cluster. Galaxies appear to form an almost one-dimensional family in parameter space. It remains a mystery why the luminosity-diameter relation for galaxies is so insensitive to environment.

The redhaired in Japan : Dutch influence on Japanese cartography (1640-1853)
Creators: name: Jacobs, Elisabeth Maria
Publisher: name: University of British Columbia
Year: 2010

description: In examining the spread of Dutch cartographical knowledge to Japan, this thesis intends to throw some light on a neglected chapter of the history of the West-European expansion of the sixteenth to nineteenth centuries. The thesis is based on the George H. Beans collection of Japanese maps of the Tokugawa era (1603-1868) preserved in the University of British Columbia Library, Vancouver. Its appendix contains a full description of all fifty-nine Japanese world maps, on which the conclusions of the thesis are based. The hypothesis of distinctive and traceable Dutch influence on Japanese cartography in the period 1640-1853 has three major cornerstones: the exclusive position the Dutch held in Japan for more than two centuries after 1639, when the Japanese government closed the country to all Europeans but the Dutch; the dominant position in world cartography, both scientifically and commercially, the Dutch held during the seventeenth and part of the eighteenth century; the long cartographical tradition in Japan and the general interest in maps among the Japanese. However, the development of Japanese cartography after 1639 shows hardly any traces of Dutch influence. Instead, most Japanese world maps — the only kind which could have borne evidence of Dutch influence— were derivatives of the so-called Ricci-map, a Chinese version of a current sixteenth century European world map made by Matteo Ricci, Jesuit missionary in China around 1600. The explanation of this unexpected conclusion is threefold and has to be found in the limited accessibility of the Dutch maps to the Japanese: none of the goods the Dutch shipped to Japan became generally available to the Japanese, the cartographical works included; all things Western, including the maps, continued to be associated with all things Christian which were suspicious; and the lack of knowledge of the Dutch language prevented the dissemination of Western cartographical information.

description: Viscous solitons are strongly non-linear surface deformations generated by blowing wind over a liquid beyond a critical viscosity. Their shape and dynamics result from a balance between wind drag, surface tension and viscous dissipation in the liquid. We investigate here the influence of the liquid viscosity in their generation and propagation. Experiments are carried out using silicon oils, covering a wide range of kinematic viscosities $ν_\ell$ between 20 and 5000~mm$^2$~s$^{-1}$. \modif{We show that, for $ν_\ell> 200$~mm$^2$~s$^{-1}$, viscous solitons are sub-critically generated from an unstable initial wave train at small fetch, where the wind shear stress is larger. The properties of this initial wave train are those expected from Miles's theory of the Kelvin-Helmholtz instability of a highly viscous fluid sheared by a turbulent wind: the critical friction velocity and critical wavelength are independent of $ν_\ell$, and the phase velocity decreases as $ν_\ell^{-1}$.} We demonstrate the subcritical nature of the transition to viscous solitons by triggering them using a wavemaker for a wind velocity below the natural threshold. Finally, we analyze the flow field induced by a viscous soliton, and show that it is well described by a two-dimensional Stokeslet singularity in the far field. The resulting viscous drag implies a propagation velocity with a logarithmic correction in liquid depth, in good agreement with our measurements.

description: Human heart rate is known to display complex fluctuations. Evidence of multifractality in heart rate fluctuations in healthy state has been reported [Ivanov et al., Nature {\bf 399}, 461 (1999)]. This multifractal character could be manifested as a dependence on scale or beat number of the probability density functions (PDFs) of the heart rate increments. On the other hand, scale invariance has been recently reported in a detrended analysis of healthy heart rate increments [Kiyono et al., Phys. Rev. Lett. {\bf 93}, 178103 (2004)]. In this paper, we resolve this paradox by clarifying that the scale invariance reported is actually exhibited by the PDFs of the sum of detrended healthy heartbeat intervals taken over different number of beats, and demonstrating that the PDFs of detrended healthy heart rate increments are scale dependent. Our work also establishes that this scale invariance is a general feature of human heartbeat dynamics, which is shared by heart rate fluctuations in both healthy and pathological states.

description: We present a cosmological solution to the electroweak hierarchy problem. After discussing general features of cosmological approaches to naturalness, we extend the Standard Model with two light scalars very weakly coupled to the Higgs and present the mechanism, which we recently introduced in a companion paper to explain jointly the electroweak hierarchy and the strong-CP problem. In this work we show that this solution can be decoupled from the strong-CP problem and discuss its possible implementations and phenomenology. The mechanism works with any standard inflationary sector, it does not require weak-scale inflation or a large number of e-folds, and does not introduce ambiguities related to eternal inflation. The cutoff of the theory can be as large as the Planck scale, both for the Cosmological Constant and for the Higgs sector. Reproducing the observed dark matter relic density fixes the couplings of the two new scalars to the Standard Model, offering a target to future axion or fifth force searches. Depending on the specific interaction of the scalars with the Standard Model, the mechanism either yields rich phenomenology at colliders or provides a novel joint solution to the strong-CP problem. We highlight what predictions are common to most realizations of cosmological selection of the weak scale and will allow to test this general framework in the near future.

New results on solar neutrino fluxes from 192 days of Borexino data
Creators: name: The Borexino Collaboration
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)

description: We report the direct measurement of the ^7Be solar neutrino signal rate performed with the Borexino detector at the Laboratori Nazionali del Gran Sasso. The interaction rate of the 0.862 MeV ^7Be neutrinos is 49+-3(stat)+-4(syst) counts/(day * 100ton). The hypothesis of no oscillation for ^7Be solar neutrinos is inconsistent with our measurement at the 4sigma level. Our result is the first direct measurement of the survival probability for solar nu_e in the transition region between matter-enhanced and vacuum-driven oscillations. The measurement improves the experimental determination of the flux of ^7Be, pp, and CNO solar nu_e, and the limit on the magnetic moment of neutrinos.

description: The young system RX J0529.3+1210 was initially identified as a single-lined spectroscopic binary. Using high-resolution infrared spectra, acquired with NIRSPEC on Keck II, we measured radial velocities for the secondary. The method of using the infrared regime to convert single-lined spectra into double-lined spectra, and derive the mass ratio for the binary system, has been successfully used for a number of young, low-mass binaries. For RX J0529.3+1210, a long- period(462 days) and highly eccentric(0.88) binary system, we determine the mass ratio to be 0.78+/-0.05 using the infrared double-lined velocity data alone, and 0.73+/-0.23 combining visible light and infrared data in a full orbital solution. The large uncertainty in the latter is the result of the sparse sampling in the infrared and the high eccentricity: the stars do not have a large velocity separation during most of their ~1.3 year orbit. A mass ratio close to unity, consistent with the high end of the one sigma uncertainty for this mass ratio value, is inconsistent with the lack of a visible light detection of the secondary component. We outline several scenarios for a color difference in the two stars, such as one heavily spotted component, higher order multiplicity, or a unique evolutionary stage, favoring detection of only the primary star in visible light, even in a mass ratio ~1 system. However, the evidence points to a lower ratio. Although RX J0529.3+1210 exhibits no excess at near-infrared wavelengths, a small 24 micron excess is detected, consistent with circumbinary dust. The properties of this binary and its membership in Lambda Ori versus a new nearby stellar moving group at ~90 pc are discussed. We speculate on the origin of this unusual system and on the impact of such high eccentricity on the potential for planet formation.

Study of quark and gluon jet substructure in Z+jet and dijet events from pp collisions

Year: 2021
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: Measurements of jet substructure describing the composition of quark- and gluon-initiated jets are presented. Proton-proton (pp) collision data at $\sqrt{s}$ =13 TeV collected with the CMS detector are used, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. Generalized angularities are measured that characterize the jet substructure and distinguish quark- and gluon-initiated jets. These observables are sensitive to the distributions of transverse momenta and angular distances within a jet. The analysis is performed using a data sample of dijet events enriched in gluon-initiated jets, and, for the first time, a Z+jet event sample enriched in quark-initiated jets. The observables are measured in bins of jet transverse momentum, and as a function of the jet radius parameter. Each measurement is repeated applying a "soft drop" grooming procedure that removes soft and large angle radiation from the jet. Using these measurements, the ability of various models to describe jet substructure is assessed, showing a clear need for improvements in Monte Carlo generators.

title: Jung and Buddhism : a hermeneutical engagement with the Tibetan and Zen Buddhist traditions
Creators: name: Yogo, Rinako
Publisher: name: University of Kent
Year: 2021

description: This thesis examines Jung's relation to Buddhism, in particular, the Tibetan and Zen Buddhist traditions from a hermeneutic perspective. It addresses the way Jung attempted to make a dialogue between Analytical Psychology and Buddhism and the extent to which he was successful. Jung's approach to Buddhism is sometimes affected by Eurocentric prejudices, which led him to misunderstand some of the concepts of Buddhism. Moreover, from the standpoint of a psychologist, Jung had a tendency to reduce Buddhist thought to its psychological aspects, and not to pay sufficient attention to its traditional meanings. Jung was also highly selective in his use of Buddhist texts and focussed on those texts which appeared to confirm, or conform to, his psychological thinking, but dismissed other Buddhist materials which had no common base with his psychology. To contrast his approach, this thesis examines the theory of the phenomenology of religion, which emphasises the recognition of the irreducibility of religious phenomena and claims that we must understand religion within its own cultural context. From the perspective of the phenomenology of religion, Jung's methodology lacks objectivity and fails to exercise epoche, which means a suspension of one's own judgement or the exclusion of every possible presupposition. Rather, Jung seems to over-emphasise eidetic vision, which is a form of subjectivity that implies an intuitive grasp of the essentials of a situation in its wholeness.There are important achievements in Jung's engagement with Buddhism and indeed Jung should be regarded as a pioneer in this field of research. Jung's writings on Buddhism had a major influence on later studies of the various Buddhist traditions and meditation in relation to Western psychology and its therapeutic techniques. From this more positive perspective, this thesis explores in detail the strengths and shortcomings of Jung's engagement with the different Buddhist traditions, in order to assess its potential contribution to the contemporary dialogue between East and West.

description: AbstractThe [Cu(btec)0.5DMF] (H4btec= 1,2,4,5-benzenetetracarboxylate acid) was electrosynthesized on the graphite working electrode by applying catholic potential. The [Cu(btec)0.5DMF] grows on a graphite surface which results from the coordination of 1,2,4,5-benzenetetracarboxylate anions with Cu2+ cations. The electrosynthesized [Cu(btec)0.5DMF] was characterized by X-ray diffraction, scanning electron microscopy. Furthermore, POAP/Cu(btec)0.5DMF nanocomposite film electrosynthesized on the surface of the carbon paste electrode by cyclic voltammetry. Different electrochemical methods including galvanostatic charge–discharge experiments, cyclic voltammetry and electrochemical impedance spectroscopy are carried out in order to investigate the performance of the system. This work introduces new nanocomposite materials for electrochemical redox capacitors with advantages including ease synthesis, high active surface area and stability in an aqueous electrolyte.

description: In this paper, we give an explicit construction of dynamical systems (defined within a solid torus) containing any knot (or link) and arbitrarily knotted chaos. The first is achieved by expressing the knots in terms of braids, defining a system containing the braids and extending periodically to obtain a system naturally defined on a torus and which contains the given knotted trajectories. To get explicit differential equations for dynamical systems containing the braids, we will use a certain function to define a tube neigbourhood of the braid. The second one, generating chaotic systems, is realized by modeling the Smale horseshoe.

We start with the ground state characterization of the superconducting flux and charge qubits. Then, by making use of a dressed state approach we describe the qubits' spectroscopy when the qubit is irradiated by a microwave field which is tuned to the gap frequency. The last section of the paper is devoted to continuous monitoring of qubit states by using a DC SQUID in the inductive mode.

A study in phenomenalism
Creators: name: Giles, James Leigh
Publisher: name: University of British Columbia
Year: 2010

description: The philosophical theory of perception called phenomenalism had its beginnings in the empirical philosophy of Locke and the subsequent criticism by Berkeley. Although Berkeley improves on Locke's account in many ways, it is not until Hume that the way is cleared for a purely empirical theory of perception. Hume, however, does not follow this through. Mill likewise encounters difficulties, though of a different sort than Hume's, in his attempt to deal with perception empirically. With Price and Ayer we have the appearance of modern phenomenalism which, in the latter's case is finally presented as a thoroughgoing empiricism. Price, however, falls into confusion when he attempts to introduce certain physical concepts. Ayer too, in the end, rejects phenomenalism. However, his argument in this regard is fallacious. The problem of translating physical object language into sense-data language relies mainly on an argument of Austin's which Coval and Todd demonstrate to be untenable. The problem of the given, as presented by Sellers, is likewise unacceptable as it is based on a misunderstanding of the analysis of perception and sense-data language. Williams' critique fairs no better as it rests upon a misconception of the concept of ineffability. It is concluded that phenomenalism has withstood the force of these attacks and that various other problems which have a bearing on phenomenalism still need inquiry.
Universal quantum computation and quantum error correction using discrete holonomies

description: Holonomic quantum computation exploits a quantum state's non-trivial, matrix-valued geometric phase (holonomy) to perform fault-tolerant computation. Holonomies arising from systems where the Hamiltonian traces a continuous path through parameter space have been well-researched. Discrete holonomies, on the other hand, where the state jumps from point to point in state space, have had little prior investigation. Using a sequence of incomplete projective measurements of the spin operator, we build an explicit approach to universal quantum computation. We show that quantum error correction codes integrate naturally in our scheme, providing a model for measurement-based quantum computation that combines the passive error resilience of holonomic quantum computation and active error correction techniques. In the limit of dense measurements we recover known continuous-path holonomies.

description: We present results for the top quark pair cross section at the Tevatron and the LHC. We use the resummed double differential cross section, employing the fully kinematics-dependent soft anomalous dimension matrices, to calculate the soft-gluon contributions at next-to-next-to-leading order (NNLO). We improve and update our previous estimates by refining our methods, including further subleading terms, and employing the most recent parton distribution function sets. The NNLO soft corrections significantly enhance the NLO cross section while considerably reducing the scale dependence. We provide a detailed discussion of all theoretical uncertainties in our calculation, including kinematics, scale, and parton distributions uncertainties and clarify the differences between our work and other approaches in the literature.

description: CuO/NiO nanoparticles were synthesized in the presence of PEG400 by depositional in alkaline environment. CuO/NiO nanoparticles were characterized by FT-IR, UV-Vis, SEM, X-ray diffraction (XRD), and EDAX. Results of XRD analysis show the crystal structure of Bunsenite (NiO) and Tenorite (CuO). The SEM photographs show granular and plate morphology of nanoparticles with high uniformity. The as-prepared nanoparticles are applied as catalyst in oxidation reaction. Effect of different parameters such as time, temperature, the kind of solvent and oxidant, and amount of oxidant on oxidation reaction were investigated in detail. The results show under the optimized reaction condition, between different substrates (cyclohexene, α-methyl styrene and styrene) using TBHP as oxidant, chloroform as solvent, and CuO/NiO as catalyst, 100% conversion of α-methyl styrene has been achieved where selectivity of acetophenone was 76%.

description: This study presents a comprehensive and innovative exploration of how the surface potential energy landscape influences meander formation. Using the Vicinal Cellular Automaton model, which distinguishes surface diffusion from adatom incorporation into the crystal, the research delves into various factors affecting surface pattern dynamics. By isolating the diffusion process within a defined energy potential, the study provides a detailed analysis of how changes in the potential energy well and the barrier at the top of the step contribute to meander formation. Remarkably, the results reveal that the mere presence of a potential well at the step's bottom is sufficient to induce meandering. The role of the Ehrlich-Schwoebel barrier on formed meanders is further investigated, and a mechanism for meander formation is proposed to clarify this process. The derived relation successfully reflects the wavelength of the meandered patterns observed in the simulations, emphasizing its reliability. Overall, the results illustrate the crucial influence of the surface energy potential's shape in driving surface pattern formation.

description: Systems whose underlying classical dynamics are chaotic exhibit signatures of the chaos in their quantum mechanics. We investigate the possibility of using time-dependent density functional theory (TDDFT) to study the case when chaos is induced by electron-interaction alone. Nearest-neighbour level-spacing statistics are in principle exactly and directly accessible from TDDFT. We discuss how the TDDFT linear response procedure can reveal the mechanism of chaos induced by electron-interaction alone. A simple model of a two-electron quantum dot highlights the necessity to go beyond the adiabatic approximation in TDDFT.

description: These lecture notes concern the semi-holomorphic 4d Chern-Simons theory and its applications to classical integrable field theories in 2d and in particular integrable sigma-models. After introducing the main properties of the Chern-Simons theory in 3d, we will define its 4d analogue and explain how it is naturally related to the Lax formalism of integrable 2d theories. Moreover, we will explain how varying the boundary conditions imposed on this 4d theory allows to recover various occurences of integrable sigma-models through this construction, in particular illustrating this on two simple examples: the Principal Chiral Model and its Yang-Baxter deformation. These notes were written for the lectures delivered at the school "Integrability, Dualities and Deformations", that ran from 23 to 27 August 2021 in Santiago de Compostela and virtually.

description: Recent observations by pulsar timing arrays (PTAs) indicate a potential detection of a stochastic gravitational wave (GW) background. Metastable cosmic strings have been recognized as a possible source of the observed signals. In this paper, we propose an $R$-invariant supersymmetric new inflation model. It is characterized by a two-step symmetry breaking $\mathrm{SU}(2) \to \mathrm{U}(1)_G \to \mathrm{nothing}$, incorporating metastable cosmic strings. The field responsible for the initial symmetry breaking acts as the inflaton, while the second symmetry breaking occurs post-inflation, ensuring the formation of the cosmic string network without monopole production. Our model predicts symmetry breaking scales consistent with the string tensions favored by PTA data, $G_\mathrm{N} μ_\mathrm{str} \sim 10^{-5}$, where $G_\mathrm{N}$ is the Newton constant. Notably, a low reheating temperature is required to suppress non-thermal gravitino production from the decay of inflaton sector fields. This also helps evading LIGO-Virgo-KAGRA constraints, while yielding a distinctive GW signature that future PTA and interferometer experiments can detect. Additionally, we examine the consistency of this scenario with non-thermal leptogenesis and supersymmetric dark matter.

toolbox

description: The Horizon 2020 project EOSC-Life brings together the 13 Life Science ‘ESFRI’ research infrastructures to create an open, digital and collaborative space for biological and medical research. Sharing sensitive data is a specific challenge within EOSC-Life. For that purpose, a toolbox is developed, providing information to researchers who wish to share or use sensitive data. The authors developed a categorisation system designed to support consistent labelling and categorisation of the resources stored in the toolbox in terms most relevant to data sharing tasks and activities, so that they are available to users (e.g., as on screen filters) when searching the system. The poster describes the methods and main results of a pilot study set to evaluate the proposed categorisation system for the toolbox resources with respect to applicability, reliability, sustainability and consistency. The primary objective of the pilot study was to identify the main improvements that are necessary to arrive at an inter-community, well understood and commonly approved categorisation system.

The nutritive value of barley for broilers
Creators: name: Chan, Robert D. Y.
Publisher: name: University of British Columbia
Year: 2010

description: Availability of Ca, P, Mg, Mn, Cu and Zn were determined from six barley samples using broiler chicks. Each of the barley samples was compared with corn in respect to growth performance and feed conversion. Metabolizable energy of barley and corn samples were evaluated by using a recently developed method. The results of this study indicate that six minerals were highly available from barley sampies with values of 93.9%, 85.2%, 81.4%, 70.4%, 71.3% and 76.5% for Ca, P, Mg, Mn, Zn and Cu, respectively. Variations in availability of minerals among some of the barley samples were observed. Supplying each barley sample in the control diet at approximately 20% or 40% of the total cereal grains at the expense of corn resulted in no alteration in growth performance, feed consumption and feed conversion to the control except for one barley sample which differed only in feed conversion at 40% composition of cereal grains. Metabolizable energy of barley and corn samples were comparable. These values correlate with the performance of the broiler chicks. The results of this study suggest that the availability values from feedstuffs should be considered in formulating diets and that the values from N.R.C. publications may not accurately represent the nutritive quality of a feedstuff.

description: According to Witten [1], the conformal boundary condition of gravity, which specifies the conformal geometry of the boundary and the trace of the extrinsic curvature, is elliptic and leads to well-defined perturbation theory of gravity about any classical solution. The conformal boundary condition was previously considered in [2, 3] in the context of AdS/BCFT, wherein the equation of motion of the end-of-the-world was derived and emphasized. In this paper, we investigate further other consequences of the conformal boundary condition in AdS/BCFT. We derive the boundary central charges of the holographic Weyl anomaly and show that they are exactly the same for conformal boundary condition and Dirichlet boundary condition. We analysis the metric perturbation with conformal boundary condition (CBC), Dirichlet boundary condition (DBC) and Neumann boundary condition (NBC) imposed on the end-of-the-world brane and show that they admit an interpretation as the fluctuation of the extrinsic curvature (case of CBC and DBC) and the induced metric (case of NBC) of Q respectively. In all cases, the fluctuation modes are massive, which are closely relevant to the massive island formation in the literature. Our results reveal that there are non-trivial gravitational dynamics from extrinsic curvatures on the conformal and Dirichlet branes, which may have interesting applications to the island. We also discuss, in passing, the localization of gravitons in brane world theory. We find that, contrary to NBC, the graviton for CBC/DBC is located on the brane with non-positive tension instead of non-negative tension.

description: We study exclusive $J/ψ$ and $Υ$ photoproduction for proton and Pb targets in the high-energy limit, with the energy dependence computed using the linear Balitsky-Fadin-Kuraev-Lipatov and the nonlinear Balitsky-Kovchegov evolution equations. The difference between these two evolution equations can be directly attributed to gluon saturation physics. We find that for proton targets there is no difference between the two approaches at the energies of the currently available data, while for Pb targets in $J/ψ$ production the data shows a clear preference for the evolution with gluon saturation.

description: AbstractPhotocatalyst has been of considerable interest due to its new technology for environmental pollution. Among the photocatalyst semiconductors, titanium dioxide is known as a photo-catalyst for the removal of environmental contaminants. In this research, we first designed anew self-made laboratory photocatalytic reactor and then photocatalytic properties of TiO2nanoparticles are studied by using UV-A light and photodegradation of methylene blue as a water pollutant evaluated until the photocatalytic process optimizes with the process parameters. The parameters that were examined include: initial dye concentration, the mass of TiO2nanoparticle, pH value, and TiO2nano-sized particles. Absorbance spectra were measured using a spectrophotometer and the concentration of the test solution was calculated by using the Beer-Lambert Law. Our test results showed that the photocatalytic UV-A/TiO2nanoparticle is a promising method for treating wastewater. The most important part is that with reduction of TiO2particles from nano to micro scale, photodegradation time becomes very slowly and even did not reach to zero after 5 h. Also, photocatalyst reaction efficiency for 10 nm TiO2nanoparticles improves to 90% within one hour and photodegradation completed after two hours, it means that the photocatalyst activity increases with increasing surface area.
