Alloy nanoparticles

description: Metal nanoparticles are of significant interest because of the exceptionally high surface areas, high density of low-coordination atoms on the surface and changes of phase stability and miscibility. Due to the synergistic effects between different metal atoms, binary or ternary alloy NPs are often more likely to display superior catalytic activity, selectivity, and stability. M [subscript x] Re₁₀₀₋ [subscript x] (M= noble metals, e.g. Pt, Pd, Rh, Ir, Ru) binary NP catalysts have been reported to be effective for biomass conversion processes. However, the impregnation method used could not control the structure of the NPs. Herein, the synthesis of Pt [subscript x] Re₁₀₀₋ [subscript x] and Pd [subscript x] Re₁₀₀₋ [subscript x] NPs by colloidal methods was explored. Pt₇₂Re₂₈ alloy nanoparticles were successfully synthesized by solvothermal method at 200 ℃, while Pd [subscript x] Re₁₀₀₋ [subscript x] alloy NPs could not be obtained under the same condition. The tunability theory developed for hydrogenation activity on bimetallic alloys revealed that ternary alloy NPs have much greater tunability of H binding energy and substrate binding energy by changing compositions. Rh [subscript x] Pd [subscript y] M₁₀₀₋ [subscript x-y] (M=Au or Cu) alloy NPs of different compositions were synthesized using the μw-assisted wet-chemical method developed by our group. The catalytic performance of Rh [subscript x] Pd [subscript y] Au₁₀₀₋ [subscript x-y] NPs was tested by catalyzing the vapor phase hydrogenation of crotonaldehyde.
Locally Preferred Structure and Frustration in Glassforming Liquids: A Clue to Polyamorphism?

description: We propose that the concept of liquids characterized by a given locally preferred structure (LPS) could help in understanding the observed phenomenon of polyamorphism. ``True polyamorphism'' would involve the competition between two (or more) distinct LPS, one favored at low pressure because of its low energy and one favored at high pressure because of its small specific volume, as in tetrahedrally coordinated systems. ``Apparent polyamorphism'' could be associated with the existence of a poorly crystallized defect-ordered phase with a large unit cell and small crystallites, which may be illustrated by the metastable glacial phase of the fragile glassformer triphenylphosphite; the apparent polyamorphism might result from structural frustration, i. e., a competition between the tendency to extend the LPS and a global constraint that prevents tiling of the whole space by the LPS.

description: The complex resistivity $\hatρ(ω)$ of the vortex lattice in an untwinned crystal of 93-K $\rm YBa_2Cu_3O_7$ has been measured at frequencies $ω/2π$ from 100 kHz to 20 MHz in a 2-Tesla field $\bf H\parallel c$, using a 4-probe RF transmission technique that enables continuous measurements versus $ω$ and temperature $T$. As $T$ is increased, the inductance ${\cal L}_s(ω) ={\rm Im} \hatρ(ω)/ ω$ increases steeply to a cusp at the melting temperature $T_m$, and then undergoes a steep collapse consistent with vanishing of the shear modulus $c_{66}$. We discuss in detail the separation of the vortex-lattice inductance from the `volume' inductance, and other skin-depth effects. To analyze the spectra, we consider a weakly disordered lattice with a low pin density. Close fits are obtained to $ρ_1(ω)$ over 2 decades in $ω$. Values of the pinning parameter $κ$ and shear modulus $c_{66}$ obtained show that $c_{66}$ collapses by over 4 decades at $T_m$, whereas $κ$ remains finite.

description: Dissimilatory iron reduction and sulfate reduction are the most important processes for anaerobic mineralization of organic carbon in marine sediments. The thermodynamics and kinetics of microbial Fe(III) reduction depend on the characteristics of the Fe(III) minerals, which influence the potential of Fe(III)-reducers to compete with sulfate-reducers for common organic substrates. In the present study, we tested different methods to quantify and characterize microbially reducible Fe(III) in sediments from a transect in Kongsfjorden, Svalbard, using different standard sequential endpoint extractions and time-course extractions with either ascorbate or a Fe(III)-reducing microbial culture. Similar trends of increasing ‘reactive Fe’ content of the sediment along the fjord transect were found using the different extraction methods. However, the total amount of ‘reactive Fe’ extracted differed between the methods, due to different Fe dissolution mechanisms and different targeted Fe fractions. Time-course extractions additionally provided information on the reactivity and heterogeneity of the extracted Fe(III) minerals, which also impact the favorability for microbial reduction. Our results show which fractions of the existing Fe extraction protocols should be considered ‘reactive’ in the sense of being favorable for microbial Fe(III) reduction, which is important in studies on early diagenesis in marine sediments.

description: We show that the mass of ionized gas in the Broad Line Regions (BLRs) of luminous QSOs is at least several hundred Msun, and probably of order 10^3-10^4 M_sun. BLR mass estimates in several existing textbooks suggest lower values, but pertain to much less luminous Seyfert galaxies or include only a small fraction of the ionized/emitting volume of the BLR. The previous estimates also fail to include the large amounts of BLR gas that emit at low efficiency (in a given line), but that must be present based on reverberation and other studies. Very highly ionized gas, as well as partially ionized and neutral gas lying behind the ionization zones, are likely additional sources of mass within the BLR. The high masses found here imply that the chemical enrichment of the BLR cannot be controlled by mass ejection from one or a few stars. A significant stellar population in the host galaxies must be contributing. Simple scaling arguments based on normal galactic chemical enrichment and solar or higher BLR metallicities show that the minimum mass of the enriching stellar population is of order 10 times the BLR mass, or greater than 10^4-10^5 M_sun. More realistic models of the chemical and dynamical evolution in galactic nuclei suggest that much larger, bulge-size stellar populations are involved.

description: The dynamics of a trapped Bose-condensed gas at finite temperatures is described by a generalized Gross-Pitaevskii equation for the condensate order parameter and a semi-classical kinetic equation for the thermal cloud, solved using $N$-body simulations. The two components are coupled by mean fields as well as collisional processes that transfer atoms between the two. We use this scheme to investigate scissors modes in anisotropic traps as a function of temperature. Frequency shifts and damping rates of the condensate mode are extracted, and are found to be in good agreement with recent experiments.

description: Cobb-Douglas production function has been used to measure the effect of various factors on pond fish output. The chosen factors were stocking of fish seed, fertilizer and artificial feed, human labour, farm size, age of pond, depth of pond water, and number of pond owner. Considering the aggregate production for all locations, it was found that, except the depth of pond water, all of her factors were statistically significant in explaining the variation of pond fish output but the results varied in different locations.

description: A new formula relating the analytic continuation of the Hurwitz zeta function to the Euler gamma function and a polylogarithmic function is presented. In particular, the values of the first derivative of the real part of the analytic continuation of the Hurwitz zeta function for even negative integers and the imaginary one for odd negative integers are explicitly given. The result can be of interest both on mathematical and physical side, because we are able to apply our new formulas in the context of the Spectral Zeta Function regularization, computing the exact pair production rate per space-time unit of massive Dirac particles interacting with a purely electric background field.

description: We extract the multiple-epoch Balmer-line profiles of the heavily obscured quasar 3C 445 from the spectral curves in the literature, and analyze the emission-line profiles of the H$α$ and H$β$ lines and the profile variability in the H$α$ line in the large time interval of more than three decades. The profile comparison between the H$α$ and H$β$ lines shows that both Balmer lines share the profile with the same form, while the blue system of the H$β$ line is seriously weaker than that of the H$α$ line. Moreover, the blue system of the H$α$ line suddenly disappeared completely and then did not appear again, however the other two components did not exhibit significant variation in the velocity or the amplitude. These findings suggest that the blue system of 3C 445, as with SDSS J153636.22+044127.0 and its analogs, is probable the result of the shock-heated outflowing gases. The observation angle of almost edge-on which the previous studies suggested can easily produce the high-speed and high-temperature shock in the collision between the massive outflow and the inner surface of the dusty torus.

description: We discuss a one-dimensional model of a fluctuating interface with a dynamic exponent $z=1$. The events that occur are adsorption, which is local, and desorption which is non-local and may take place over regions of the order of the system size. In the thermodynamic limit, the time dependence of the system is given by characters of the $c=0$ conformal field theory of percolation. This implies in a rigorous way a connection between CFT and stochastic processes. The finite-size scaling behavior of the average height, interface width and other observables are obtained. The avalanches produced during desorption are analyzed and we show that the probability distribution of the avalanche sizes obeys finite-size scaling with new critical exponents.

Entropic Bounds For Unitary Testers and Mutually Unbiased Unitary Bases

description: We define the entropic bounds, i.e minimal uncertainty for pairs of unitary testers in distinguishing between unitary transformations not unlike the well known entropic bounds for observables. We show that in the case of specific sets of testers which pairwise saturate the trivial zero bound, the testers are all equivalent in the sense their statistics are the same. On the other hand, when maximal bounds are saturated by such sets of testers, the unitary operators would form unitary bases which are mutually unbiased. This resembles very much the role of mutually unbiased bases in maximizing the entropic bounds for observables. We show how such a bound can be useful in certain quantum cryptographic protocols.

description: It is shown that the timelike asymptotic properties of thermal correlation functions in relativistic quantum field theory can consistently be described in terms of free fields carrying some stochastic degree of freedom which couples to the thermal background. These ``asymptotic thermal fields'' have specific algebraic properties (commutation relations) and their dynamics can be expressed in terms of asymptotic field equations. The formalism is applied to interacting theories where it yields concrete non-perturbative results for the asymptotic thermal propagators. The results are consistent with the expected features of dissipative propagation of the constitutents of thermal states, outlined in previous work, and they shed new light on the non-perturbative effects of thermal backgrounds.

Our synapse follows the rules of Spike-Timing Dependent Plasticity (STDP). We show that this plasticity of the coupling between neurons produces enlarged frequency locking zones and results in synchronization that is more rapid and much more robust against noise than classical synchronization arising from connections with constant strength. We also present a simple discrete map model that demonstrates the generality of the phenomenon.

description: We study the influence of converging cooling flow bulk motions on the Sunyaev-Zel'dovich (SZ) effect. To that purpose we derive a modified Kompaneets equation which takes into account the contribution of the accelerated electron media of the cooling flow inside the cluster frame. The additional term is different from the usual kinematic SZ-effect, which depends linearly on the velocity, whereas the contribution described here is quadratic in the macroscopic electron fluid velocity, as measured in the cluster frame. For clusters with a large cooling flow mass deposition rate and/or a small central electron density, it turns out that this effect becomes relevant.

description: Every year fish farming diseases respond to 102 billion dollars in losses worldwide, mostly due to limitations in early pathogen detection. Environmental DNA (eDNA) arrives as a tool worldwide used by its capacity to monitor and detect the organism’s presence. On Tambaqui’s farming Neoechinorhynchus buttnerae (Acanthocephala) is the bottle-neck. N. buttnerae is an endoparasite with no free life stages and requires an intermediate host in its lifecycle, the Cypridopsis vidua (Ostracoda). Tambaqui (Colossoma macropomum) is the second most farmed fish in Brazil, thrived by its qualities (high resistance and productivity, market demand and low-cost production). The study’s goal is to develop a molecular tool able to detect pathogens even in a low parasite density environment. Gene sequences for N. buttnerae aren’t available on global platforms (INSDC), which is fundamental to develop eDNA species-specific primers and probes protocol.

Calculated infrared intensities are in accord with experimental studies. There have been no ab initio attempts at determining which interactions account for the fourth-order anisotropy. We show that vibrationally induced distortions of the molecule contribute to the fourth-order anisotropy Hamiltonian and that the magnitude and sign of the effect (-6.2 K) is in good agreement with all experiments. Vibrationally induced tunnel splittings in isotopically pure and natural samples are predicted.

description: We solve the problem of a Bose or Fermi gas in $d$-dimensions trapped by $% δ\leq d$ mutually perpendicular harmonic oscillator potentials. From the grand potential we derive their thermodynamic functions (internal energy, specific heat, etc.) as well as a generalized density of states. The Bose gas exhibits Bose-Einstein condensation at a nonzero critical temperature $T_{c}$ if and only if $d+δ>2$, and a jump in the specific heat at $T_{c}$ if and only if $d+δ>4$. Specific heats for both gas types precisely coincide as functions of temperature when $d+δ=2$. The trapped system behaves like an ideal free quantum gas in $d+δ$ dimensions. For $δ=0$ we recover all known thermodynamic properties of ideal quantum gases in $d$ dimensions, while in 3D for $δ=$ 1, 2 and 3 one simulates behavior reminiscent of quantum {\it wells, wires}and{\it dots}, respectively.

Synthesis and Biomedical Applications of Gamma Peptide Nucleic Acid

Subjects: subject: 39999 Chemical Sciences not elsewhere classified
subject: FOS: Chemical sciences

description: Nucleic acid is a promising material for biomedical applications due to its programmability and predictability of sequence binding. However, native nucleic acid itself could not be widely exploited in in vivo applications because of enzymatic degradation, weak and off-targeting binding and cellular delivery. Such issues could be potentially addressed by a novel synthetic nucleic acid analogue called Gamma Peptide Nucleic Acid (γPNA), in which backbone is replaced with a gamma modified N-(2- aminoethyl)-glycine. Nonetheless, the biomedical applications of γPNA will impede until the synthesis and binding properties are better investigated. The presented work in this Dissertation first offers a robust synthetic strategy for preparing optically pure γPNA monomers. The strategy utilizes a bulky temporary
protecting group to shield the alpha proton of the aminoaldehyde intermediate and performs reductive amination to build the γPNA backbone. As a result, the final monomers have enantiomeric excess more than 99.5% confirmed by HPLC and 19F NMR. This methodology will facilitate the production of γPNA for a wider range of applications. Earlier, γPNA is demonstrated to be preorganized into either right-handed (RH) or left-handed (LH) motifs by simply inverting the stereochemistry at γ position. The RH motif can bind to RH-γPNA, unmodified PNA and native nucleic acid with exquisite binding affinity and sequence specificity, while the LH motif can only bind to LH-γPNA and unmodified PNA. The second work presented in this Dissertation demonstrates that the sequence information embedded in conformationally orthogonal γPNA can be interconverted by toehold-mediated strand displacement reaction. This work opens up the opportunities for developing orthogonal molecular circuits to rapidly and sensitively detect genetic materials. Designing a tight binding hybridization probe with high sequence specificity is
challenging in that the probes are too stable to be sensitive to a base mispairing. Inspired by Nature’s template-directed assembly, the third work presented in this Dissertation
demonstrates a relatively weak binding MPγPNA probe can be concatenated in the presence of disease-relevant RNA repeated expansions and becomes a tight binding and
potentially selective hybridization probe. This work may benefit the development of future nucleic acid therapeutics.
Together, this Dissertation offers a robust synthetic strategy for preparing optically pure γPNA monomers, systematically understands the binding relationships of γPNA and
provides a novel strategy to in-situ assemble tight binding probe with high sequence selectivity. This work envisions γPNA as a versatile biomolecular self-assembly platform
with control over sequence and helical sense and will hopefully facilitate the potential applications of γPNA in diagnostics and therapeutics.

description: While cadmium telluride (CdTe) thin films are being used in solar cell prototyping for decades, the recent advent of two-dimensional (2D) materials challenges the fundamental limit for thickness of conventional CdTe layers. Here, we report our theoretical predictions on photocarrier dynamics in an ultimately thin (about 1 nm) CdTe slab. It corresponds to a layer that is just a single unit cell thick, when the bulk parent crystal in the zinc blende phase is cleaved along the [110] facet. Using an \textit{ab-initio} method based on density functional theory (DFT) and the Boltzmann equation in the relaxation time approximation (RTA), we determine the thermalization time for charge carriers excited to a certain energy for instance through laser irradiation. Our calculations include contributions arising from all phonon branches in the first Brillouin zone (BZ), thus capturing all relevant inter- and intraband carrier transitions due to electron-phonon scattering. We find that the photocarrier thermalization time is strongly reduced, by one order of magnitude for holes and by three orders of magnitude for electrons, once the CdTe crystal is thinned down from the bulk to a monolayer. Most surprisingly, the electron thermalization time becomes independent of the electron excess energy up to about 0.5~eV, when counted from the conduction band minimum (CBM). We relate this peculiar behavior to the degenerate and nearly parabolic lowest conduction band that yields a constant density of states (DOS) in the 2D limit. Our findings may be useful for designing novel CdTe-based optoelectronic devices, which employ nonequilibrium photoexcited carriers to improve the performance.

description: Theoretical calculations, computer simulations and experiments indicate the possible existence of a ferromagnetic liquid state. Should such a state exist, demagnetization effects would force a nontrivial magnetization texture governed by the shape of the liquid droplet. Since liquid droplets are deformable, the droplet shape couples to the magnetization texture. This paper solves the joint shape/texture problem subject to the assumption of cylindrical droplet symmetry. The shape undergoes a change in topology from spherical to toroidal as exchange energy grows or surface tension decreases.

description: Relative moduli spaces of periodic monopoles provide novel examples of Asymptotically Locally Flat hyperkahler manifolds. By considering the interactions between well-separated periodic monopoles, we infer the asymptotic behavior of their metrics. When the monopole moduli space is four-dimensional, this construction yields interesting examples of metrics with self-dual curvature (gravitational instantons). We discuss their topology and complex geometry. An alternative construction of these gravitational instantons using moduli spaces of Hitchin equations is also described.

description: In the strongly damped regime, the convective gain rate for stimulated scatter varies inversely with the plasma wave damping rate. Electron trapping effects reduce the damping but also lead to loss of resonance for large enough amplitude waves. This leads to a gain rate bound and corresponding optimum scattered light frequency and plasma wave amplitude.

description: This multiple-methods study used extant surveys and semi-structured interviews to look at the experiences of first-generation students who participated in a concurrent enrollment program in high school and later enrolled at the University of Texas at Austin as full-time college students. A qualitative analysis of 4,264 beginning- and end-of-course surveys and 21 semi-structured interviews (of both first- and continuing-generation students) found that first-generation students had strong ideas about postsecondary success concepts, which were enhanced through rigorous coursework and positive support networks. The combination of surveys and interviews allowed for the examination of the transition from high school to college, and a better understanding of how talents, strengths, motivations, and goals continue to develop, evolve, or change in college. By participating in concurrent enrollment during high school, students were given the opportunity to experience a college-level class, learn what behaviors were expected of them as college students, and negotiate various higher education idiosyncrasies. First-generation college students are often pre-judged on their ability to successfully complete a college degree, with some educators negatively categorizing them as coming from a deficit. These assumptions can discount the unique experiences, motivations, goals, and strengths of each student. This research contributes to the field of higher education by reframing the deficit mindset ingrained in the narrative around first-generation students. First-generation students are strong and capable of success in college, and it is critical to create programs that highlight their strengths rather than weaknesses. This is particularly important as concurrent enrollment programs continue to grow in Texas and at the national level.

description: We report on the successful sounding rocket flight of the high resolution (R=3000-4000) J-PEX EUV spectrometer. J-PEX is a novel normal incidence instrument, which combines the focusing and dispersive elements of the spectrometer into a single optical element, a multilayer-coated grating. The high spectral resolution achieved has had to be matched by unprecedented high spatial resolution in the imaging microchannel plate detector used to record the data. We illustrate the performance of the complete instrument through an analysis of the 220-245A spectrum of the white dwarf G191-B2B obtained with a 300 second exposure. The high resolution allows us to detect a low-density ionized helium component along the line of sight to the star and individual absorption lines from heavier elements in the photosphere.

description: We propose a new radion stabilization mechanism in the Randall-Sundrum spacetime, introducing a bulk ${SU(N_H)}$ gauge field which confines at a TeV scale. It turns out that the radion is stabilized by the balance between a brane tension and a pressure due to the Casimir energy of the strong ${SU(N_H)}$ gauge field. We investigate the phase transition between the Randall-Sundrum (compactified) spacetime and a de-compactified spacetime and determine the parameter regime in which eternal (old) inflation is avoided and the phase transition can be completed. In comparison to the Goldberger-Wise mechanism, the 5D Planck mass can be larger than the AdS curvature and a classical description of the gravity is reliable in our stabilization mechanism. We also discuss the effect of the phase transition in cosmology such as an entropy dilution and a production of gravitational waves.

description: A method to identify the parity of unconventional superconductors is proposed based on tunneling spectroscopy. For a model of calculation, we adopt a ferromagnet/superconductor (F/S) junction of which tunneling current is spin polarized. The tunneling conductance spectra are shown to be quite sensitive to the direction of the magnetization axis in the ferromagnet only when the superconductor has odd parity. Therefore, it is possible to distinguish the parity of the superconductor by measuring the tunneling spectroscopy in F/S junctions.
