description: Whilst intense solar flares are almost always accompanied by a coronal mass ejection (CME), reports on stellar CMEs are rare, despite the frequent detection of stellar 'super flares'. The torus instability of magnetic flux ropes is believed to be one of the main driving mechanisms of solar CMEs. Suppression of the torus instability, due to a confining background coronal magnetic field that decreases sufficiently slowly with height, may contribute to the lack of stellar CME detection. Here we use the solar magnetic field as a template to estimate the vertical extent of this 'torus-stable zone' (TSZ) above a stellar active region. For an idealised potential field model comprising the fields of a local bipole (mimicking a pair of starspots) and a global dipole, we show that the upper bound of the TSZ increases with the bipole size, the dipole strength, and the source surface radius where the coronal field becomes radial. The boundaries of the TSZ depend on the interplay between the spots' and the dipole's magnetic fields, which provide the local- and global-scale confinement, respectively. They range from about half the bipole size to a significant fraction of the stellar radius. For smaller spots and an intermediate dipole field, a secondary TSZ arises at a higher altitude, which may increase the likelihood of 'failed eruptions'. Our results suggest that the low apparent CME occurrence rate on cool stars is, at least partially, due to the presence of extended TSZs.

The adsorption of selected antibiotics by Kaolin

description: In this investigation, the in vitro adsorption of tetracycline hydrochloride, neomycin sulfate, lincomycin hydrochloride, chloramphenicol, and ampicillin trihydrate by kaolin were studied. Adsorption studies were carried out at 37.0°C. in water and in pH 1.2, 3.0, and 5.0 solutions. The adsorption isotherms for tetracycline hydrochloride, neomycin sulfate, and lincomycin hydrochloride in aqueous solution were of the Langmuir type, with the following exceptions. (a) A Ereundlich adsorption isotherm was obtained for tetracycline hydrochloride in pH 1.2 solutions. (b) An S type adsorption isotherm, (according to the classification of isotherms by Giles and his coworkers (1960) was obtained for lincomycin hydrochloride in pH 1.2 solutions. In general, adsorption varied with the pH of the solutions. Chloramphenicol and ampicillin trihydrate are not adsorbed by kaolin. Desorption studied for the adsorbed antibiotics were carried out in. water. The results indicated that the adsorption of tetracycline hydrochloride by kaolin is a reversible process, the adsorption of neomycin sulfate by kaolin is an irreversible process, and the adsorption of lincomycin hydrochloride is a partially reversible process. On the basis of data obtained, it was found that 47.21% of 250 mg. tetracycline hydrochloride dose and, 57.98% neomycin base (220.5 mg.) would be adsorbed by six gm. of kaolin. On the basis of a 500 mg. dose of 1incornycin hydrochloride/ 11.44% would be.expected to be adsorbed by.six gm. of kaolin. This value increases to 33.94% if 17.76 gm. of kaolin are' administered to the patient. If the above two values are compared to the in vivo data reported by Wagner (1966), it becomes evident that the decrease in plasma levels (by about 90%) is much greater than that which would be predicted on the basis of in vitro adsorption studies. However, Wagner (1966) studied a commercial preparation (Kaopectate) and it-may be that other ingredients contribute to the dramatic decrease in blood levels. Therefore, in vitro data cannot be.disregarded but, at the same time > should not be extrapolated to in vivo drug effects. The final proof must come from carefully control studies in man.

description: The possibility of mining the rotational energy from black holes has far--reaching implications. Such energy extraction could occur even for isolated black holes, if hypothetical ultralight bosonic particles exist in Nature, leading to a new equilibrium state $-$ a black hole with synchronised bosonic hair $-$ whose lifetime could exceed the age of the Universe. A natural question is then: for an isolated black hole and at maximal efficiency, how large is the energy fraction $ε$ that can be extracted from a Kerr black hole by the superradiant growth of the dominant mode? In other words, how hairy can the resulting black hole become? A thermodynamical bound for the total superradiance efficiency, $ε\lesssim 0.29$ (as a fraction of the initial black hole mass), has long been known, from the area law. However, numerical simulations exhibiting the growth of the dominant mode only reached about one third of this value. We show that if the development of superradiant instabilities is approximately conservative (as suggest by the numerical evolutions), this efficiency is limited to $ε\lesssim 0.10$, regardless of the spin of the bosonic field. This is in agreement with the maximum energy extraction obtained in numerical simulations for a vector field and predicts the result of similar simulations with a scalar field, yet to be performed.

description: A new formula for elastic bending modulus of monolayer graphene is derived analytically from an empirical potential for solid-state carbon-carbon bonds. Two physical origins are identified for the non-vanishing bending modulus of the atomically thin graphene sheet, one due to the bond angle effect and the other resulting from the bond order term associated with dihedral angles. The analytical prediction compares closely with ab initio energy calculations. Pure bending of graphene monolayers are simulated by a molecular mechanics approach, showing slight nonlinearity and anisotropy in the tangent bending modulus as the bending curvature increases. An intrinsic coupling between bending and in-plane strain is noted for graphene monolayers rolled into carbon nanotubes.

description: We consider a nonlocal scalar field theory inspired by the tachyon action in open string field theory. The Lorentz-covariant action is characterized by a parameter $ξ^2$ that quantifies the amount of nonlocality. Restricting to purely time-dependent configurations, we show that a field redefinition perturbative in $ξ^2$ reduces the action to a local two-derivative theory with a $ξ^2$-dependent potential. This picture is supported by evidence that the redefinition maps the wildly oscillating rolling tachyon solutions of the nonlocal theory to conventional rolling in the new scalar potential. For general field configurations we exhibit an obstruction to a local Lorentz-covariant formulation, but we can still achieve a formulation local in time, as well as a light-cone formulation. These constructions provide an initial value formulation and a Hamiltonian. Their causality is consistent with a lack of superluminal behavior in the nonlocal theory.

description: We study the correlation between the locations of galaxy-galaxy strong lensing candidates and tracers of large-scale structure from both weak lensing or X-ray emission. The COSMOS survey is a unique data set, combining deep, high resolution and contiguous imaging in which strong lenses have been discovered, plus unparalleled multiwavelength coverage. To help interpret the COSMOS data, we have also produced mock COSMOS strong and weak lensing observations, based on ray-tracing through the Millenium simulation. In agreement with the simulations, we find that strongly lensed images with the largest angular separations are found in the densest regions of the COSMOS field. This is explained by a prevalence among the lens population in dense environments of elliptical galaxies with high total-to-stellar mass ratios, which can deflect light through larger angles. However, we also find that the overall fraction of elliptical galaxies with strong gravitational lensing is independent of the local mass density; this observation is not true of the simulations, which predict an increasing fraction of strong lenses in dense environments. The discrepancy may be a real effect, but could also be explained by various limitations of our analysis. For example, our visual search of strong lens systems could be incomplete and suffer from selection bias; the luminosity function of elliptical galaxies may differ between our real and simulated data; or the simplifying assumptions and approximations used in our lensing simulations may be inadequate. Work is therefore ongoing. Automated searches for strong lens systems will be particularly important in better constraining the selection function.

description: We report \textit{Spitzer} full-orbit phase observations of the eccentric hot Jupiter XO-3b at 3.6 and 4.5 $μ$m. Our new eclipse depth measurements of $1770 \pm 180$ ppm at 3.6 $μ$m and $1610 \pm 70$ ppm at 4.5 $μ$m show no evidence of the previously reported dayside temperature inversion. We also empirically derive the mass and radius of XO-3b and its host star using Gaia DR3's parallax measurement and find a planetary mass $M_p=11.79 \pm 0.98 ~M_{\rm{Jup}}$ and radius $R_p=1.295 \pm 0.066 ~R_{\rm{Jup}}$. We compare our \textit{Spitzer} observations with multiple atmospheric models to constrain the radiative and advective properties of XO-3b. While the decorrelated 4.5 $μ$m observations are pristine, the 3.6 $μ$m phase curve remains polluted with detector systematics due to larger amplitude intrapixel sensitivity variations in this channel. We focus our analysis on the more reliable 4.5 $μ$m phase curve and fit an energy balance model with solid body rotation to estimate the zonal wind speed and the pressure of the bottom of the mixed layer. Our energy balance model fit suggests an eastward equatorial wind speed of $3.13 ^{+0.26} _{-0.83}$ km/s, an atmospheric mixed layer down to $2.40 ^{+0.92} _{-0.16}$ bar, and Bond albedo of $0.106 ^{+0.008} _{-0.106}$. We assume that the wind speed and mixed layer depth are constant throughout the orbit. We compare our observations with a 1D planet-averaged model predictions at apoapse and periapse and 3D general circulation model (GCM) predictions for XO-3b. We also investigate the inflated radius of XO-3b and find that it would require an unusually large amount of internal heating to explain the observed planetary radius.

description: We present S82-20, an unusual redshift $\approx$3 object identified in SDSS-Stripe 82 broad-band images. The rest-frame ultraviolet spectrum of S82-20 shows emission lines from highly ionized species, including HeII $λ$1640, and the CIV $λλ$1548, 1550 and OVI $λλ$1032, 1038 doublets. The high Ly$α$ luminosity ($3.5\times 10^{44}$ erg s$^{-1}$), the high emission line equivalent widths ($>200$Å for Ly$α$), the FWHM of the emission lines ($<800$km s$^{-1}$), and the high ionization OVI line strongly support the interpretation that S82-20 is a Type~II QSO. However, photoionization models using Type~II QSO do not fully explain the measured CIV/HeII line ratio, which requires either some contribution from star-formation or high velocity shocks. Additionally, S82-20 is not detected at wavelengths longer than 2$μ$m, in tension with the expectation of isotropically IR emission of a luminous QSO. We consider the possibility that S82-20 is a rare example of a changing-look QSO, observed in a temporarily low state, where the broad line region has faded, while the narrow line region still emits emission line. Otherwise, it may be a rare case of the short phase of the life of a massive galaxy, in which active star formation and accretion onto a supermassive black hole coexist.

Milton’s better fortitude : a study of the nature of heroism in Paradise lost
Creators: name: Jones, Paul Arthur
Publisher: name: University of British Columbia
Year: 2010

description: Because critics have continued to discuss Paradise Lost according to classical standards of heroism, the question of the poem's hero has been needlessly vitiated. Not until Milton's concept of heroism is clearly understood can any scholarly discussion of the epic's hero, or heroes, proceed. Our endeavour in this present study will be not to discover the poem's "hero" so much as to understand clearly that form of heroism, those qualities of character and action, which the poem espouses. Milton found that the classical heroic ideal was sharply at odds with his understanding of Christian heroism. He rejected the destructive, self-glorifying, self-reliant hero, epitomized by Achilles, in favour of one who would embody the Christian ethic of love, humility, and faith. In attempting to define artistically "the better fortitude/Of Patience and Heroic Martyrdom" in Paradise Lost Milton begins by painting in Books I to III an impressive picture of false heroism in Satan and by presenting the alternative of true heroism in the Son. By undermining the classical heroism of Satan while exalting at the same time the nobility of the Son, Milton orients the reader to the standards of heroism upon which the epic is founded. The first main movement within Paradise Lost dealing with the heroic nature of Adam and Eve consists largely of a process of education instituted by the Father through the Archangel Raphael intended to clarify for man the issues involved in maintaining his original heroic standing. The War in Heaven serves to emphasize for both unfallen man and the reader the heroism of obedience by displaying a showpiece of Christian fortitude, Abdiel, and by revealing the terrible results of disobedience which befall Satan and his followers. The first movement concerning the heroism of Adam and Eve in Paradise Lost ends in the trial of their obedience, the heroic contest between man and Satan. The fall is significant for Milton as a negation of those qualities which are involved in his concept of heroism, and he implies that if noble acts of Christian heroes are more glorious than those of other heroes, acts of villainy by the former are more heinous than the sins of the latter. Doubt, revealed first in Adam by his questioning of divine providence in his talk with Raphael, prevents Adam from exercising the heroic faith which would have sought a solution to his dilemma in an appeal to the love and wisdom of God. The second main movement within Paradise Lost dealing with the heroism of man is complementary to the first, consisting largely of a process of education instituted by the Father through the Archangel Michael by means of which Adam and Eve's heroic stature is restored. Milton stresses here the importance of God's grace for the existence of true heroism. The patient submission of Adam and Eve to their expulsion from Eden is an act of Christian heroism which signifies their restoration as heroes.

description: La tesi studia l’intermediazione attuata da agenti costituenti il campo letterario, nel processo di ammissione di autori esordienti. E’ il processo che inizia con un aspirante autore, con un dattiloscritto inedito, e termina con una casa editrice che accetta il dattiloscritto per la pubblicazione. Il risultato è duplice: da un lato permette una comprensione nuova e profonda del campo letterario italiano, che non ha ricevuto sufficiente attenzione. Dall’altro, lo studio dei processi di intermediazione ha ricadute teoriche più generali. 
Il campo letterario, così come definito da Bourdieu, comprende tutti gli agenti e le istituzioni che, da posizioni diverse, contribuiscono alla produzione simbolica e materiale dei libri, in quanto oggetti culturali. In questo ambito, teorie sull’intermediazione che ci sono utili sono la definizione bourdesiana di intermediario culturale, il concetto di gate-keeper, utilizzato come metafora dei filtri che si frappongono al flusso della produzione di oggetti culturali, quello di knowledge broker, figura in grado di generare innovazione, svolgendo un ruolo di intermediazione della conoscenza fra domini in cui esiste ma non è fruttuosa ed altri in cui non esiste e, infine, quella di intermediari studiati dall’economia della qualità, che non fanno scelte di produzione o consumo, ma influenzano le scelte fatte dai consumatori. 
Coerentemente con la sua natura esplorativa e l’approccio induttivo, la ricerca è condotta attraverso 64 interviste semistrutturate ad agenti del campo letterario italiano: editor, editori, agenti letterari, scrittori ed altri agenti, che svolgano un ruolo di intermediazione. Il primo risultato è una descrizione ricca del campo letterario italiano e degli agenti ed istituzioni che lo costituiscono. Si analizzano i criteri di selezione di autori ed opere inedite ed i canali che permettono l’accesso al campo letterario, insieme agli intermediari che li attivano. Degli intermediari si analizzano aspetti soggettivi ed oggettivi, per capire chi siano, cosa fanno e perché.

description: We present the first results of a deep $Chandra$ observation of the galaxy cluster RBS 797, whose previous X-ray studies revealed two pronounced X-ray cavities in the east-west (E-W) direction. Follow-up VLA radio observations of the central active galactic nucleus (AGN) uncovered different jet and lobe orientations, with radio lobes filling the E-W cavities and perpendicular jets showing emission in the north-south (N-S) direction over the same scale ($\approx$30 kpc). With the new $\sim$427 ks total exposure, we report the detection of two additional, symmetric X-ray cavities in the N-S direction at nearly the same radial distance as the E-W ones. The newly discovered N-S cavities are associated with the radio emission detected at 1.4 GHz and 4.8 GHz in archival VLA data, making RBS 797 the first galaxy cluster found to have four equidistant, centrally-symmetric, radio-filled cavities. We derive the dynamical and radiative ages of the four cavities from X-ray and radio data, respectively, finding that the two outbursts are approximately coeval, with an age difference of $\lessapprox$10 Myr between the E-W and N-S cavities. We discuss two scenarios for the origin of the two perpendicular, equidistant cavity systems: either the presence of a binary AGN which is excavating coeval pairs of cavities in perpendicular directions, or a fast ($

description: Carbonyl compounds are very important volatil organic compounds receiving increasing attention due to their critical role in tropospheric organic chemistry and to their effects on human health. They are first photo-oxidation stage of almost all organic compounds and originators of free radicals (OH, O3...). Therfore, continuous determination of their atmospheric concentrations is essential. Currently, field measurements are very limited mainly because of the analytical challenges posed by trace concentrations and interferences arising from atmospheric co-pollutants. Additionally, hydroxyl radical (OH) plays a central role in atmospheric chemistry processes. The measurement of atmospheric OH concentrations is essential for the comprehension of atmospheric chemical and photochemical processes. 
In this context, objectives of this work were:
To perform a continuous survey of atmospheric concentrations of carbonyl compounds on different sites around the area of Bologna. For this purpose, an automatic instrument for the continuous measurement (one hour of time resolution) was developed and used. Additionally, the development of a complete and original analytical method was realised.
To develop an original OH generation system in order to evaluate the effect of OH and the reactivity of solid and/or liquid materials of interest. This included the validation of an analytical method for the quantification of OH concentrations generated. Effect of OH on ceramic materials and reactivity of snow surface samples, involved as sink of OH in atmospheric chemistry, were evaluated.

An interpretation of Peruzzi’s frieze in the Sala Del Fregio, Villa Farnesina, Rome
Creators: name: Jensen, Josephine
Publisher: name: University of British Columbia
Year: 2010

description: Although the fresco decoration of Agostino Chigi's Villa Farnesina in Rome has received much scholarly attention, the precise meaning of the decoration in several of the rooms is still not known. This thesis is concerned with one of these rooms, the Sala del Fregio, on the ground floor, which contains a continuous frieze running around the top of the four walls. This frieze was painted by Baldessare Peruzzi in 1512. While ten of the mythological stories represented in the frieze have been identified, there is a large segment of it for which no satisfactory explanation has been given. Furthermore, to date, only one scholar has tentatively suggested a theme for the entire decoration of this room, which interpretation, however, is not totally convincing. In this thesis, a literary source for the unidentified part of the frieze is proposed, and a new interpretation of the meaning of the entire decoration is given. It is suggested that not one literary text, i.e., Ovid's Metamorphoses was used in the formulation of this frieze, but several, very specific texts. These texts are all post-classical, where the authors concerned have interpreted the myths allegorically. An analysis of these texts has made it possible to come to a more definite conclusion regarding the meaning of the frieze. The recurrent theme that emerges from this analysis of sources centres on the Neo-Platonic doctrine of the immortality of the soul. The second part of the thesis examines this Neo-Platonic doctrine of immortality as it may relate to the patron, Agostino Chigi, and it attempts to answer the question: What special significance could this subject have had for the patron himself? At almost exactly the same date when Peruzzi painted the frieze in the Sala del Fregio, i.e., 1512, Agostino Chigi commissioned Raphael to design and decorate his mortuary chapel in the Church of S. Maria del Popolo. In the mosaic decoration of the cupola of the mausoleum, as has already been established by Shearman, the same Neo-Platonic doctrine of the immortality of the soul is expressed. A relationship of theme, therefore, exists between the idea stated in the cupola of the mausoleum and the frieze in the Sala del Fregio. This thesis explores the connection between the two programs and, as part of this exploration, proposes a leading Augustinian scholar and Platonist, Egidio da Viterbo, as the most likely humanist adviser for both programs. In conclusion, the thesis considers, but only briefly, the themes of the classical subjects depicted in the other major rooms of the ground floor of the Villa Farnesina, to see whether these also contain allusions to immortality. It is suggested that they do, and this raises the possibility which is, however, another full subject for research not broached in this thesis, that there may be, in fact, a unified program for the whole villa, one centered on the doctrine of the immortality of the soul.

description: We perform a three-dimensional nested-grid radiation magneto-hydrodynamics (RMHD) simulation with self-gravity to study the early phase of the low-mass star formation process from a rotating molecular cloud core to a first adiabatic core just before the second collapse begins. Radiation transfer is handled with the flux-limited diffusion approximation, operator-splitting and implicit time-integrator. In the RMHD simulation, the outer region of the first core attains a higher entropy and the size of first core is larger than that in the magnetohydrodynamics simulations with the barotropic approximation. Bipolar molecular outflow consisting of two components is driven by magnetic Lorentz force via different mechanisms, and shock heating by the outflow is observed. Using the RMHD simulation we can predict and interpret the observed properties of star-forming clouds, first cores and outflows with millimeter/submillimeter radio interferometers, especially the Atacama Large Millimeter/submillimeter Array (ALMA).

description: This paper reports on detailed measurements of the performance of Resistive Plate Chambers in a proton beam with variable intensity. Short term effects, such as dead time, are studied using consecutive events. On larger time scales, for various beam intensities the chamber.s efficiency is studied as a function of time within a spill of particles. The correlation between the efficiency of chambers placed in the same beam provides an indication of the lateral size of the observed effects. The measurements are compared to the predictions of a simple model based on the assumption that the resistive plates behave as pure resistors.

description: In this paper, we argue that AI ethics must move beyond the concepts of race-based representation and bias, and towards those that probe the deeper relations that impact how these systems are designed, developed, and deployed. Many recent discussions on ethical considerations of bias in AI systems have centered on racial bias. We contend that antiblackness in AI requires more of an examination of the ontological space that provides a foundation for the design, development, and deployment of AI systems. We examine what this contention means from the perspective of the sociocultural context in which AI systems are designed, developed, and deployed and focus on intersections with anti-Black racism (antiblackness). To bring these multiple perspectives together and show an example of antiblackness in the face of attempts at de-biasing, we discuss results from auditing an existing open-source semantic network (ConceptNet). We use this discussion to further contextualize antiblackness in design, development, and deployment of AI systems and suggest questions one may ask when attempting to combat antiblackness in AI systems.

description: Interacting populations often create complicated spatiotemporal behavior, and understanding it is a basic problem in the dynamics of spatial systems. We study the two-species case by simulations of a host--parasitoid model. In the case of co-existence, there are spatial patterns leading to noise-sustained oscillations. We introduce a new measure for the patterns, and explain the oscillations as a consequence of a timescale separation and noise. They are linked together with the patterns by letting the spreading rates depend on instantaneous population densities. Applications are discussed.

description: The origin of individual differences in infant social attention is not yet well understood. Previous research suggests two different possibilities: One explains these differences with varying experiences in parent-child interaction styles (Dunphy-Lelii et al., 2014), while the other points at differences in infant temperament as a central factor (LaBounty et al., 2018). There is a lack of published research combining these two approaches in a single study. The goal of this study is to test whether parent-child interaction as well as temperament are able to predict later infant social attention. We further wish to compare the predictive power of these two constructs with each other and investigate whether shy temperament in early toddlerhood is related to social attention as well. Data from a longitudinal sample of mother-child dyads from a mid-sized city in Germany are being investigated. A total of 165 dyads took part in this study, though only a subset of the complete sample will be relevant for our work. Mother-child interaction was measured via video-taped observations of a free play session using the Emotional Availability Scales (Biringen, 2008) at 6 months. Infant temperament was assessed with the Infant Behavior Questionnaire Revised (Gartstein & Rothbart, 2003) at 6 months, while shy temperament was assessed with the Early Childhood Behavior Questionnaire (Putnam et al., 2006) at 18 months. A habituation paradigm was employed to measure infant social attention at 12 months.

description: The dry reforming of methane (DRM) has been proposed as an efficient way to convert two greenhouse gases, namely CO2 and CH4 to syngas. However, most catalysts reported in the literature suffer from strong deactivation during the reforming reaction. The deactivation is caused by strong sintering of catalytically active nanoparticles and the formation of filamentous carbon. Herein a new synthesis procedure based on molecular layer deposition (MLD) is established to stabilize DRM catalysts under reaction conditions. Deactivation of a Ni/SiO2 reference catalyst was prevented by forming a defined porous net-like over-layer, which prevents the sintering and detachment of Ni nanoparticles by filamentous carbon. The MLD approach was further compared to the formation of an overlayer by atomic layer deposition (ALD), demonstrating the advantages of MLD forming hybrid organic-inorganic alucone layers over classical alumina ALD.

description: Let $a, b$ and $n > 1$ be three positive integers such that $a$ and $\sum_{j=0}^{n-1} b^j$ are relatively prime. In this paper, we prove that the toric ideal $I$ associated to the submonoid of $\mathbb{N}$ generated by $\{\sum_{j=0}^{n-1} b^j\} \cup \{\sum_{j=0}^{n-1} b^j + a\, \sum_{j=0}^{i-2} b^j \mid i = 2, \ldots, n\}$ is determinantal. Moreover, we prove that for $n > 3$, the ideal $I$ has a unique minimal system of generators if and only if $a < b-1$.

description: The physics and applications of fiber-based supercontinuum (SC) sources have been a subject of intense interest over the last decade, with significant impact on both basic science and industry. New uses for SC sources are also constantly emerging due to their unique properties that combine high brightness, multi-octave frequency bandwidth, fiber delivery, and single-mode output. The last few years have seen significant research efforts focused on extending the wavelength coverage of SC sources towards the 2 to 20 $μ$m molecular fingerprint mid-infrared (MIR) region and in the ultraviolet (UV) down to 100 nm, while also improving stability, noise and coherence, output power, and polarization properties. Here we review a selection of recent advances in SC generation in a range of specialty optical fibers, including fluoride, chalcogenide, telluride, and silicon-core fibers for the MIR; UV-grade silica fibers and gas-filled hollow-core fibers for the UV range; and all-normal dispersion fibers for ultralow-noise coherent SC generation.

description: ZnO is a remarkable material with many applications in electronics and catalysis. Atomic layer deposition (ALD) of ZnO on flat substrates is an industrially applied and well-known process. Various studies describe the growth of ZnO layers on flat substrates. However, the growth characteristics and reaction mechanisms of atomic layer deposition of ZnO on mesoporous powders have not been well studied. This study investigates the ZnO ALD process based on diethylzinc (DEZn) and water with silica powder as substrate. In-situ thermogravimetric analysis gives direct access to the growth rates and reaction mechanisms of this process. Ex-situ analytics, e.g., N2 sorption analysis, XRD, XRF, HRTEM, and STEM-EDX mapping, confirm deposition of homogenous and thin films of ZnO on SiO2. In summary, this study offers new insights into the fundamentals of an ALD process on high surface area powders.
