description: Exact analytical solutions are derived for the Stokes flows within evaporating sessile drops of spherical and cylindrical cap shapes. The results are valid for arbitrary contact angle. Solutions are obtained for arbitrary evaporative flux distributions along the free surface as long as the flux is bounded at the contact line. The field equations, E^4(Psi)=0 and Del^4(Phi)=0, are solved for the spherical and cylindrical cap cases, respectively. Specific results and computations are presented for evaporation corresponding to uniform flux and to purely diffusive gas phase transport into an infinite ambient. Wetting and non-wetting contact angles are considered with the flow patterns in each case being illustrated. For the spherical cap with evaporation controlled by vapor phase diffusion, when the contact angle lies in the range 0

description: We report a scalable linear optical scheme for generating entangled states of multiple ququarts in which the individual single-ququart state is prepared with the biphoton polarization state of frequency-nondegenerate spontaneous parametric down-conversion. The output state is calculated with the full consideration of the higher order effect (double-pair events) of spontaneous parametric down-conversion. Scalability to multiple-ququart entanglement is demonstrated with examples: linear optical entanglement of three and four individual biphoton ququarts.

description: Developing reduced-order models for turbulent flows, which contain dynamics over a wide range of scales, is an extremely challenging problem. In statistical mechanics, the Mori-Zwanzig (MZ) formalism provides a mathematically formal procedure for constructing reduced-order representations of high-dimensional dynamical systems, where the effect due to the unresolved dynamics are captured in the memory kernel and orthogonal dynamics. Turbulence models based on MZ formalism have been scarce due to the limited knowledge of the MZ operators, which originates from the difficulty in deriving MZ kernels for complex nonlinear dynamical systems. In this work, we apply a recently developed data-driven learning algorithm, which is based on Koopman's description of dynamical systems and Mori's linear projection operator, on a set of fully-resolved isotropic turbulence datasets to extract the Mori-Zwanzig operators. With data augmentation using known turbulence symmetries, the extracted Markov term, memory kernel, and orthogonal dynamics are statistically converged and the Generalized Fluctuation-Dissipation Relation can be verified. The properties of the memory kernel and orthogonal dynamics, and their dependence on the choices of observables are investigated to address the modeling assumptions that are commonly used in MZ-based models. A series of numerical experiments are then constructed using the extracted kernels to evaluate the memory effects on predictions. Results show that the prediction errors are strongly affected by the choice of observables and can be further reduced by including the past history of the observables in the memory kernel.

description: Theoretical axion models state that axions are very weakly interacting particles. In order to experimentally detect them, the use of colorful and inspired techniques becomes mandatory. There is a wide variety of experimental approaches that were developed during the last 30 years, most of them make use of the Primakoff effect, by which axions convert into photons in the presence of an electromagnetic field. We review the experimental techniques used to search for axions and will give an outlook on experiments planned for the near future.

description: Backward angle (u-channel) scattering provides complementary information for studies of hadron spectroscopy and structure, but has been less comprehensively studied than the corresponding forward angle case. As a result, the physics of u-channel scattering poses a range of new experimental and theoretical opportunities and questions. We summarize recent progress in measuring and understanding high energy reactions with baryon charge exchange in the u-channel, as discussed in the first backward angle (u-channel) Physics Workshop. In particular, we discuss backward angle measurements and their theoretical description via both hadronic models and the collinear factorization approach, and discuss planned future measurements of u-channel physics. Finally, we propose outstanding questions and challenges for u-channel physics.

description: Most patients with cystic fibrosis have the risk of pathogenic bacteria being exchanged between their sinuses and lungs. A method for topical application of antibiotics where the antibiotics persist for a long period of time is needed. Ten patients with cystic fibrosis and bacterial sinusitis were included. Autologous platelet rich fibrin was mixed with an antibiotic solution and sprayed onto the mucosa at the end of an endoscopic sinus surgery; Colistin, a Ciprofloxacin-Colistin combination or Tobramycin was used. The antibiotic concentration was measured in the sinonasal mucus four, seven and 13 days after surgery. Nine patients had Pseudomonas aeruginosa in their nose/sinuses at the time of surgery; in eight of these P. aeruginosa was not detected by culture at the final visit. In the majority of the ten included patients the antibiotics were continuously released for more than 7 days. No severe side effects were seen. Autologous platelet rich fibrin co-delivered with antibiotics is a feasible method for topical antibiotic treatment in supplementary to sinus surgery. We expect that this treatment is successful for eradication of sinonasal bacterial infections in immunosuppressed patients suffering from recalcitrant sinus infections. The efficacy should be evaluated in randomized controlled trials.

Fish cell DNA repair and breakage assays for assessing aquatic genotoxicity
Creators: name: Walton, Douglas G.
Publisher: name: University of British Columbia
Year: 2010

description: It is claimed that many cancers in man are causally related to chemical carcinogen exposure. Similarly epidemiological studies of fish populations have associated an elevated tumor incidence with environments contaminated with chemicals, some of which have demonstrated carcinogenic activity. Sampling and pathologically screening large numbers of fish is labour intensive, costly, time-consuming, and field studies provide only circumstantial evidence for an etiological agent. A variety of quick and inexpensive assays have been used with mammalian cells to detect probable carcinogenic activity by analyzing for DNA-damaging events. More recently fish cells and metabolizing enzymes are being used in these assays in order to provide tests with more relevance to the aquatic environment, validate mammalian test results, determine fish cell sensitivity to genotoxic agents, and, ultimately, to develop techniques to directly assess the genotoxic:carcinogenic potential of a particular environment. The present study initially compared the DNA repair response in fish and mammalian cells. Although the measured repair response of fish cells was found to be very low, in comparison to mammalian cells, the assay procedure was altered to increase the fish cell sensitivity. Despite being able to detect DNA repair in fish cells treated with 3,4-benzopyrene the repair technique was felt to lack the sensitivity necessary for in vivo monitoring. However, the low amount of repair measurable in fish cells suggested that tests for DNA breakage may be more sensitive. Subsequent comparative experimentation with the chromosome aberration and micronucleus tests confirmed this. Treatment of fish cells with 3,4-benzopyrene resulted in chromosome aberrations. Polycyclic aromatic hydrocarbons like 3,4-benzopyrene are important aquatic contaminants and have been found in elevated concentrations in sediments from Sturgeon Bank, an area near Vancouver at which a sewage treatment plant discharges. Field testing the developed genotoxicity techniques indicated cytotoxicity and chromosome aberrations, but no DNA repair, in cultured fish and mammalian cells exposed to Sturgeon Bank sediment extracts. However, in a parallel test, an in vivo increase in micronuclei frequency in starry flounder could not be demonstrated.

description: We present the first review of the current state of the literature on electronic properties and phase transitions in TlX and TlMX2 (M = Ga, In; X = Se, S, Te) compounds. These chalcogenides belong to a family of the low-dimensional semiconductors possessing chain or layered structure. They are of significant interest because of their highly anisotropic properties, semi- and photoconductivity, non-linear effects in their I-V characteristics (including a region of negative differential resistance), switching and memory effects, second harmonic optical generation, relaxor behavior and potential applications for optoelectronic devices. We review the crystal structure of TlX and TlMX2 compounds, their transport properties under ambient conditions, experimental and theoretical studies of the electronic structure, transport properties and semiconductor-metal phase transitions under high pressure, and sequences of temperature-induced structural phase transitions with intermediate incommensurate states. Electronic nature of the ferroelectric phase transitions in the above-mentioned compounds, as well as relaxor behavior, nanodomains and possible occurrence of quantum dots in doped and irradiated crystals is discussed.

description: Determination of air density and the quantitative estimates of water vapour adsorbed or desorbed by the surface of mass standard, remain the principals sources of uncertainties when weighing mass standard made from stainless steel or super alloy. The classical method, for air density determination, use the so called CIPM-1981/91 formula and the measured air parameters. An other approach is based only on the results of comparisons, realized successively in air and in vacuum, between special artefacts. The distribution and the state of water molecules inside the chamber of mass comparator influence the results of weighing. Also, the instruments used for air moisture measurement are either, not very sensitive (capacitive hygrometer) or disturbing for environment (dew-point hygrometer). To control that, a proposal method is given and observations of water vapour behaviour inside the enclosure for different conditions are reported. Keywords. mass metrology, air density, water vapour

description: We are revising the consistency of photometric metallicity formulae widely used for fundamental-mode RR Lyrae (RRab) variables, based on their V- and I-band light curves, published by Jurcsik and Kovács (1996) and Smolec (2005), respectively. 293 RRab variables belonging to 10 globular clusters, all simultaneously containing stars of both Oosterhoff types, are selected for this purpose. We find that on average, the V-band formula results in higher estimated metallicities by about 0.05 dex than the I-band formula. Moreover, we detect a dependency on the Oosterhoff class of the variables for both formulae, as well. Using the V-band formula, Oo I stars are 0.05-0.10 dex more metal rich than Oo II stars of the same cluster. Although with less significance, but the I-band results indicate a reversed trend. Therefore, we surmise that the average difference we have found between the V- and I-band formulae is the consequence of the total sample being dominated by Oo I variables.

description: The Cosmology Large Angular Scale Surveyor (CLASS) observes the polarized cosmic microwave background (CMB) over the angular scales of 1$^\circ \lesssim θ\leq$ 90$^\circ$ with the aim of characterizing primordial gravitational waves and cosmic reionization. We report on the on-sky performance of the CLASS Q-band (40 GHz), W-band (90 GHz), and dichroic G-band (150/220 GHz) receivers that have been operational at the CLASS site in the Atacama desert since June 2016, May 2018, and September 2019, respectively. We show that the noise-equivalent power measured by the detectors matches the expected noise model based on on-sky optical loading and lab-measured detector parameters. Using Moon, Venus, and Jupiter observations, we obtain power-to-antenna-temperature calibrations and optical efficiencies for the telescopes. From the CMB survey data, we compute instantaneous array noise-equivalent-temperature sensitivities of 22, 19, 23, and 71 $\mathrm{μK}_\mathrm{cmb}\sqrt{\mathrm{s}}$ for the 40, 90, 150, and 220 GHz frequency bands, respectively. These noise temperatures refer to white noise amplitudes, which contribute to sky maps at all angular scales. Future papers will assess additional noise sources impacting larger angular scales.

description: Global kilometre-scale resolving weather and climate models come with extreme compute requirements.Therefore, profiling, understanding and finally predicting the performance and scalability of these models is of utmost importance to efficiently leverage the compute power of today’s supercomputers on the one hand and to achieve optimal time-to-solution for the actual weather and climate predictions on the other hand. The Centre of Excellence in Simulation of Weather and Climate in Europe (ESiWACE) focuses on the development of prototypical global high-resolution models, which have recently fed into the international intercomparison project on the DYnamics of the Atmospheric general circulation Modeled On Non-hydrostatic Domains (DYAMOND). A key challenge in these developments lies - besides the scientific case of DYAMOND - in the prediction of the actual performance of models used in the communities on upcoming exascale systems.In my talk, I will present recent considerations on measuring and predicting performance of weather and climate models at the example of the ICOsahedral Non-hydrostatic (ICON) model. After introducing the context of ESiWACE and DYAMOND, I will focus on (1) scalability results of 2.5km- and 5km-resolving ICON runs and (2) on a semi-analytical performance modeling approach to predict scalability of the model on current and upcoming supercomputing architectures. Finally, I will point at the (3) capabilities of the sparse grid regression technique to predict performance from measured scalability data .

description: We consider a toy model of the interaction of a qubit with an exotic space-time containing a time-like curve. Consistency seems to require that the global evolution of the qubit be non-unitary. Given that quantum mechanics is globally unitary, this then is an example of a quantum gravity information paradox. However, we show that a careful analysis of the problem in the Heisenberg picture reveals an underlying unitarity, thus resolving the paradox.

description: We present detailed spectral and temporal characteristics both in the hard X-ray (>10 keV) and soft X-ray (<10 keV) domains, obtained using data from INTEGRAL, XMM-Newton, ASCA and RXTE. The INTEGRAL time-averaged total spectrum shows a power-law like shape with photon index Gamma = 0.93 +/- 0.06. 4U 0142+61 is detected up to 229 keV and the flux between 20 keV and 229 keV is (15.01 +/- 0.82) x 10^(-11) erg/cm^2/s. Using simultaneously collected data with the spectrometer SPI of INTEGRAL the combined total spectrum yields the first evidence for a spectral break with a peak energy of 228 +65/-41 keV. There is no evidence for significant long-term time variability of the total emission. Pulsed emission is measured with ISGRI up to 160 keV. The 20-160 keV profile shows a broad double-peaked pulse with a 6.2 sigma detection significance. The total pulsed spectrum can be described with a very hard power-law shape with a photon index Γ= 0.40 +/- 0.15. We performed phase-resolved spectroscopy over the total high-energy band (2.8-300 keV) and identify at least three genuinely different pulse components with different spectra. The high level of consistency between the detailed results from the four missions is indicative for a remarkable stable geometry underlying the emission scenario.

We study Basu-Harvey type cubic equations, fuzzy funnel configurations, and derive the M5-brane tension from the N=6 theory. We also find a limit in which the above M2-M5 system reduces to a D2-D4 system and we recover the Nahm equation from the N=6 theory. We then examine domain wall configurations in mass-deformed N=6 theory with a manifest SU(2)xSU(2)xU(1) global symmetry. We derive tensions of domain walls connecting between arbitrary M5-brane vacua of the deformed theory and observe their consistency with gravity dual expectations.

description: We use strongly coupled lattice QED with two flavors of massless staggered fermions to model the physics of pions in two-flavor massless QCD. Our model has the right chiral symmetries and can be studied efficiently with cluster algorithms. In particular we can tune the strength of the QCD anomaly and thus study its effects on the chiral phase transition. Our study confirms the widely accepted view point that the chiral phase transition is first order in the absence of the anomaly. Turning on the anomaly weakens the transition and turns it second order at a critical anomaly strength. The anomaly strength at the tricritical point is characterized using $r = (M_{η'}-M_π)/ρ_{η'}$ where $M_{η'}, M_π$ are the screening masses of the anomalous and regular pions and $ρ_{η'}$ is the mass-scale that governs the low energy fluctuations of the anomalous symmetry. We estimate that $r \sim 7 $ in our model. This suggests that a strong anomaly at the two-flavor QCD chiral phase transition is necessary to wash out the first order transition.

description: We formulate and calculate the second order quasi-normal modes (QNMs) of a Schwarzschild black hole (BH). Gravitational wave (GW) from a distorted BH, so called ringdown, is well understood as QNMs in general relativity. Since QNMs from binary BH mergers will be detected with high signal-to-noise ratio by GW detectors, it is also possible to detect the second perturbative order of QNMs, generated by nonlinear gravitational interaction near the BH. In the BH perturbation approach, we derive the master Zerilli equation for the metric perturbation to second order and explicitly regularize it at the horizon and spatial infinity. We numerically solve the second order Zerilli equation by implementing the modified Leaver's continued fraction method. The second order QNM frequencies are found to be twice the first order ones, and the GW amplitude is up to $\sim 10%$ that of the first order for the binary BH mergers. Since the second order QNMs always exist, we can use their detections (i) to test the nonlinearity of general relativity, in particular the no-hair theorem, (ii) to remove fake events in the data analysis of QNM GWs and (iii) to measure the distance to the BH.

description: We present detailed spectral and temporal characteristics over the whole X-ray band. For this purpose data have been used from INTEGRAL, RXTE and XMM-Newton. The INTEGRAL hard X-ray (>10 keV) time-averaged total spectrum, can be described by a power law with a photon index Gamma = 1.13 +/- 0.06 and extends to ~175 keV. No evidence for a spectral break is found. No significant long-term time variability has been detected above 20 keV. Pulsed emission is measured up to 270 keV (12.3 sigma; 20-270 keV). Three different pulse components can be recognized in the pulse profiles: 1) a hard pulse which contributes above ~4 keV, 2) a softer pulse not contributing in the hard X-ray domain and 3) a very soft pulse component below 2 keV. Detailed phase-resolved spectroscopy of the pulsed emission confirms long-term stability. The spectral shape gradually changes with phase from a soft single power law to a complex multi-component shape and then to a hard single power law. The spectrum switches from a very hard (Gamma = 0.99 +/- 0.05) to a very soft (Gamma = 3.58 +/- 0.34) single power-law shape within a 0.1-wide phase interval. We identify three independent components. The three shapes are a soft power law, a hard power law and a curved shape. The phase distributions of the normalizations of these spectral components form three decoupled pulse profiles. The soft component peaks around phase 0.4 while the other two components peak around phase 0.8. The width of the curved component (~0.25 in phase) is about half the width of the hard component.

description: Electrocatalytic hydrogen evolution reaction (HER) in alkaline media is a promising electrochemical energy conversion strategy. Ruthenium (Ru) is an efficient catalyst with a desirable cost for HER, however, the sluggish H2O dissociation process, due to the low H2O adsorption on its surface, currently hampers the performances of this catalyst in alkaline HER. Herein, we demonstrate that the H2O adsorption improves significantly by the construction of Ru-O-Mo sites. We prepared Ru/MoO2 catalysts with Ru-O-Mo sites through a facile thermal treatment process and assessed the creation of Ru-O-Mo interfaces by transmission electron microscope (TEM) and extended X-ray absorption fine structure (EXAFS). By using Fourier-transform infrared spectroscopy (FTIR) and H2O adsorption tests, we proved Ru-O-Mo sites have tenfold stronger H2O adsorption ability than that of Ru catalyst. The catalysts with Ru-O-Mo sites exhibited a state-of-the-art overpotential of 16 mV at 10 mA cm-2 in 1 M KOH electrolyte, demonstrating a threefold reduction than the previous bests of Ru (59 mV) and commercial Pt (31 mV) catalysts. We proved the stability of these performances over 40 hours without decline. These results could open a new path for designing efficient and stable catalysts.
The fictional image of post-Mao youth : a thematic study
Creators: name: Louis, Winnie Laifong
Publisher: name: University of British Columbia

description: The present dissertation attempts to examine fictional works written by and about contemporary Chinese youth in the post-Mao era (1976-1984). Among the several thousand stories that flooded the Chinese literary scene since the death of Mao Zedong and the fall of the "Gang of Four", Zhiqing Fiction, or fiction about urban educated youth, has played an important role in terms of its large quantity, its daring social criticism, and its comprehensive revelation of the physical and spiritual journey of contemporary Chinese urban youth since 1966. Zhiqing Fiction enables us to trace that journey from the Red Guard Movement to the rustication program and life from after returning to their city homes. In this thesis, a thematic study of Zhiqing Fiction, the existence of a cyclical pattern is demonstrated. An examination of this thematically circular pattern shows how under the influence of socio-political, literary and personal factors, an important part of Chinese literature was transformed from the affirmation of official (revolutionary) values to the negation of them and finally back to a reaffirmation of similar values in a new historical context. It further shows that, despite the relaxation of literary policy, Chinese literature has not yet escaped political influence. A political exploration of this fact is also seen to be the Chinese writers' inherent desire to influence society through literature. In this thesis portraits of post-Mao youth are discussed under five thematic categories: the Red Guard Movement, rusticated life, rediscovery of love, re-assertion of the self, and the search for new outlets. Besides supporting the cyclical model, these portraits are seen to also provide a window for understanding the loves and hates, aspirations and frustrations, ideals and disillusionments, and above all, the spirit, of contemporary Chinese youth.
The Black Hole Mass - Spheroid Luminosity relation

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The differing M_bh-Luminosity relations presented in McLure & Dunlop, Marconi & Hunt and Erwin et al. have been investigated. A number of issues have been identified and addressed in each of these studies, including but not limited to: the removal of a dependency on the Hubble constant; a correction for dust attenuation in the bulges of disc galaxies; the identification of lenticular galaxies previously treated as elliptical galaxies; and application of the same (Y|X) regression analysis. These adjustments result in relations which now predict similar black hole masses. The optimal K-band relation is log(M_bh/M_sun) = -0.37(+/-0.04)[M_K +24] + 8.29(+/-0.08), with a total (not intrinsic) scatter in log M_bh equal to 0.33 dex. This level of scatter is similar to the value of 0.34 dex from the M_bh-sigma relation of Tremaine et al. and compares favourably with the value of 0.31 dex from the M_bh-n relation of Graham & Driver. Using different photometric data, consistent relations in the B- and R-band are also provided, although we do note that the small (N=13) R-band sample used by Erwin et al. is found here to have a slope of -0.30(+/-0.06) and a total scatter of 0.31 dex. Performing a symmetrical regression on the larger K-band sample gives a slope of -0.40, implying M_bh ~ L^{1.00}. Implications for galaxy-black hole coevolution, in terms of dry mergers, are briefly discussed, as are predictions for intermediate mass black holes. Finally, as previously noted by Tundo et al., a potential bias in the galaxy sample used to define the M_bh-L relations is shown and a corrective formula provided.

description: We study s-wave superconductivity in the two-dimensional square lattice attractive Hubbard Hamiltonian for various inhomogeneous patterns of interacting sites. Using the Bogoliubov-de Gennes (BdG) mean field approximation, we obtain the phase diagram for inhomogeneous patterns in which the on-site attractive interaction U_i between the electrons takes on two values, U_i=0 and -U/(1-f) (with f the concentration of non-interacting sites) as a function of average electron occupation per site n, and study the evolution of the phase diagram as f varies. In certain regions of the phase diagram, inhomogeneity results in a larger zero temperature average pairing amplitude (order parameter) and also a higher superconducting (SC) critical temperature T_c, relative to a uniform system with the same mean interaction strength (U_i=-U on all sites). These effects are observed for stripes, checkerboard, and even random patterns of the attractive centers, suggesting that the pattern of inhomogeneity is unimportant. The phase diagrams also include regions where superconductivity is obliterated due to the formation of various charge ordered phases. The enhancement of T_{c} due to inhomogeneity is robust as long as the electron doping per site n is less than twice the fraction of interacting sites [2(1-f)] regardless of the pattern. We also show that for certain inhomogeneous patterns, when n = 2(1-f), increasing temperature can work against the stability of existing charge ordered phases for large f and as a result, enhance T_{c}.

Variations of body composition, growth and efficiency of nutrient utilization among wild and domesticated strains of rainbow trout, Salmo gairdneri
Creators: name: Ming, Frederick Warren
Publisher: name: University of British Columbia
Year: 2010

description: Strain differences in efficiency of utilization of dietary protein and energy were investigated using rainbow trout (Salmo gairdneri) from Pennask and Premier Lakes (wild strains) and a trout farm (Sun Valley strain). Endogenous losses of protein and energy varied among the strains. Sun Valley fish were concluded to have a higher basal metabolic rate and maintenance requirement, based on slopes of regression (g or kcal loss / fish/ day versus initial dry weight) for endogenous losses of protein and energy. Efficiency of protein and energy utilization were examined in two feeding trials conducted a year apart using a non-replicated factorial design comprising three strains (st), two feeding levels (fl), two dietary protein sources (pr) and two protein concentrations (co). Feed consumption (appetite) at ages 0 and 1 showed significant strain-related variation as did relative growth (R), and a number of efficiency traits: Feed Conversion Efficiency (FCE), Protein Efficiency Ratio (PER), Productive Protein Value (PPV), Net Protein Efficiency (NPE), Energy Conversion (EC), and Net Conversion of Energy (NCE). Age 0 strain ranking was consistently Sun Valley > Premier > Pennask for appetite, R and all efficiency traits except NCE . FCE and PER indicated a similar relationship among yearlings. Maintenance-corrected traits (NPE and NCE) in yearlings varied little among strains. Strain X diet interactions were significant (p<0.05) or near significant for several traits, indicating variable strain response to changes in levels of protein concentration or source. Statistically significant or near significant interactions for efficiency traits at age 0 were: st x fl (PPV, and NCE); st x pr (FCE, PER, PPV, and NCE); and st x co (FCE, NPE, and EC). Age 1 significant interactions were: st x fl (PPV), st x pr (NCE), st x co (FCE, PER and NPE). Significant or near significant st x pr and st x co interactions were observed for appetite (both years) and dry tissue growth (st x pr, age 0). Ammonia excretion, resulting from oxidation of amino acids, was evaluated for indirect comparison of strains for efficiency of protein utilization in a four-day assay at age 1. Ammonia-N excretion rate (mg NH₃/ kg BW / g diet) following consumption of one high-protein meal daily correlated inversely in rank with FCE and PER, having values of 0.30, 0.31 and 0.44 for Sun Valley, Premier and Pennask, respectively.

title: Studies of methods to restrict the grain growth of nanocrystalline metal oxides
Creators: name: Al-Angari, Yasser
Publisher: name: University of Kent
Year: 2002

description: There is considerable interest in nanocrystalline materials. This thesis is concerned with nanocrystalline oxides and the development of methods to prevent their grain growth on heating. This growth, which is evident at temperatures as low as 400°C, presents a serious problem in the study and applications of nanocrystalline oxides. The systems that were studied were nanocrystalline magnesium oxide, zirconium oxide, cerium oxide and tin oxide. The methods of preventing grain growth included the encapsulation of the oxide in the pores of porous silica, mixing with nanocrystals of alumina and treating the surface with a silanising agent, hexamethyldisilazane. All the methods employed showed some effect on reducing the grain growth. Encapsulation in the pores of silica was effective, however it proved difficult to get large amounts of the oxides into the pores. A more efficient method of preparing large samples was the incorporation of alumina, which was achieved by a sol-gel process. An alkoxide of the target oxide and an aluminium alkoxide were mixed and then hydrolsed and calcined. This proved very effective for magnesium oxide, zirconium oxide and tin oxide. For example, heating zirconium oxide at 1000°C for 60 minutes causes the nanocrystals to grow to about 50nm. Treatment with alumina restricts the growth to 12nm. Similar effects were found for the other oxides, although magnesium oxide showed a reaction with alumina at the highest temperatures. Silanising the surface was only studied for tin oxide and it restricted growth at 1000°C to 27nm, compared to 88nm for an untreated sample. A full description is given of the preparative methods and structural studies of the systems using X-ray diffraction and X-ray absorption spectroscopy.
