Volunteerism: An Anchor for Global Change through Partnerships in Learning and Service
Authors: Salas-Provance Marlene , Marchino Margarita , Escobedo Margot
Published: September 2015

Today more than ever, people are making global connections. Socially, Facebook allows us to stay in touch with family and friends around the world, as easy as swiping the iScreen. In education, millions of learners are connected digitally through Massive Open Online Programs or MOOCs. There is a worldwide sharing of knowledge every minute of every day through online learning. In healthcare, the World Health Organization (WHO) is leading the discussion on the state of disability in the world through the WHO Report on Disabilities. In our social, education, and healthcare circles, the goal is for individuals in every part of the world to engage in behaviors that will improve lives. The idea of connectivity goes further when we think of volunteerism. Volunteerism in its best sense is a benefit to the individual and society. More often than not, volunteers have deeply held beliefs about making a positive contribution as a volunteer, and are motivated by values such as social justice, equity, and freedom. As practitioners and scholars unite in shared endeavors worldwide our bonds of trust and societal cohesion grow. This leads to a story of three professionals working from a common sense of purpose, a shared vision, a destiny.

Authors: Shade Paul A. , Blank Basil , Schuren Jay C. , Turner Todd J. , Kenesei Peter , Goetze Kurt , Suter Robert M. , Bernier Joel V. , Li Shiu Fai , Lind Jonathan , Lienert Ulrich , Almer Jonathan
Published: September 2015

High energy x-ray characterization methods hold great potential for gaining insight into the behavior of materials and providing comparison datasets for the validation and development of mesoscale modeling tools. A suite of techniques have been developed by the x-ray community for characterizing the 3D structure and micromechanical state of polycrystalline materials; however, combining these techniques with in situ mechanical testing under well characterized and controlled boundary conditions has been challenging due to experimental design requirements, which demand new high-precision hardware as well as access to high-energy x-ray beamlines. We describe the design and performance of a load frame insert with a rotational and axial motion system that has been developed to meet these requirements. An example dataset from a deforming titanium alloy demonstrates the new capability.
Fluctuation-induced forces governed by the dielectric properties of water—A contribution to the hydrophobic interaction
Authors: Berthoumieux H. , Maggs A. C.
Published: September 2015

The hydrophobic interaction between objects immersed in water is typically attractive and adds to the well-known van der Waals interaction. The former supposedly dominates the latter on nanometric distances and could be of major importance in the assembly of biologic objects. Here, we show that the fluctuation-induced attraction between two objects immersed in a correlated dielectric medium which models water is the sum of a van der Waals term and a short-range contribution that can be identified as part of the hydrophobic interaction. In this framework, we calculate analytically the fluid correlation function and the fluctuation-induced interaction between small and extended inclusions embedded in water and we characterize the hydrophobic terms.
Induced representations of tensors and spinors of any rank in the Stueckelberg-Horwitz-Piron theory
Authors: Horwitz Lawrence P. , Zeilig-Hess Meir
Published: September 2015

We show that a modification of Wigner’s induced representation for the description of a relativistic particle with spin can be used to construct spinors and tensors of arbitrary rank, with invariant decomposition over angular momentum. In particular, scalar and vector fields, as well as the representations of their transformations, are constructed. The method that is developed here admits the construction of wave packets and states of a many body relativistic system with definite total angular momentum. Furthermore, a Pauli-Lubanski operator is constructed on the orbit of the induced representation which provides a Casimir operator for the Poincaré group and which contains the physical intrinsic angular momentum of the particle covariantly.
Resonant two-photon ionization spectroscopy of jet-cooled OsSi
Authors: Johnson Eric L. , Morse Michael D.
Published: September 2015

The optical spectrum of diatomic OsSi has been investigated for the first time, with transitions observed in the range from 15 212 to 18 634 cm−1 (657-536 nm). Two electronic band systems have been identified along with a number of unclassified bands. Nine bands have been investigated at rotational resolution, allowing the ground state to be identified as X3Σ0+−, arising from the 1σ21π42σ23σ21δ2 configuration. The ground X3Σ0+− state is characterized by re = 2.1207(27) Å and ΔG1/2″ = 516.315(4) cm−1 for the most abundant isotopologue, 192Os28Si (38.63%). The A1 excited electronic state, which is thought to be primarily 3Π1 in character, is characterized by T0 = 15 727.7(7) cm−1, ωe = 397.0(7) cm−1, and re = 2.236(16) Å for 192Os28Si. The B1 excited electronic state is characterized by T0 = 18 468.71 cm−1, ΔG1/2 = 324.1 cm−1, and re = 2.1987(20) Å for 192Os28Si and is thought to be primarily 1Π1 in character. These results are placed in context through a comparison to other transition metal carbides and silicides.
Physical mechanisms underlying the strain-rate-dependent mechanical behavior of kangaroo shoulder cartilage
Authors: Thibbotuwawa Namal , Oloyede Adekunle , Li Tong , Singh Sanjleena , Senadeera Wijitha , Gu YuanTong
Published: September 2015

Due to anatomical and biomechanical similarities to human shoulder, kangaroo was chosen as a model to study shoulder cartilage. Comprehensive enzymatic degradation and indentation tests were applied on kangaroo shoulder cartilage to study mechanisms underlying its strain-rate-dependent mechanical behavior. We report that superficial collagen plays a more significant role than proteoglycans in facilitating strain-rate-dependent behavior of the kangaroo shoulder cartilage. By comparing the mechanical properties of degraded and normal cartilages, it was noted that proteoglycan and collagen degradation significantly compromised strain-rate-dependent mechanical behavior of the cartilage. Superficial collagen contributed equally to the tissue behavior at all strain-rates. This is different to the studies reported on knee cartilage and confirms the importance of superficial collagen on shoulder cartilage mechanical behavior. A porohyperelastic numerical model also indicated that collagen disruption would lead to faster damage of the shoulder cartilage than when proteoglycans are depleted.
Semi-local scaling and turbulence modulation in variable property turbulent channel flows
Authors: Patel Ashish , Peeters Jurriaan W. R. , Boersma Bendiks J. , Pecnik Rene
Published: September 2015

We theoretically and numerically investigate the effect of temperature dependent density and viscosity on turbulence in channel flows. First, a mathematical framework is developed to support the validity of the semi-local scaling as proposed based on heuristic arguments by Huang, Coleman, and Bradshaw [“Compressible turbulent channel flows: DNS results and modelling,” J. Fluid Mech. 305, 185–218 (1995)]. Second, direct numerical simulations (DNS) of turbulent channel flows with different constitutive relations for density and viscosity are performed to assess and validate the semi-local scaling for turbulent statistics. The DNS database is obtained by solving the low-Mach number approximation of the Navier-Stokes equation. Finally, we quantify the modulation of turbulence due to changes in fluid properties. In the simulations, the fluid is internally heated and the temperature at both channel walls is fixed, such that the friction Reynolds number based on wall quantities is Reτ = 395 for all cases investigated. We show that for a case with variable density ρ and viscosity μ, but constant semi-local Reynolds number Reτ∗≡(ρ¯/ρw)/(μ¯/μw)Reτ (where bar and subscript w, denote Reynolds averaging and averaged wall quantity, respectively), across the whole channel height, the turbulent statistics exhibit quasi-similarity with constant property turbulent flows. For cases where Reτ∗≠Reτ across the channel, we found that quasi-similarity is maintained for cases with similar Reτ∗ distributions, even if their individual mean density and viscosity profiles substantially differ. With a decrease of Reτ∗ towards the channel center (Reτ∗<Reτ), we show that the anisotropy increases and the pre-multiplied stream-wise spectra reveal that this increase is associated with strengthening of the large scale streaks in the buffer layer. The opposite effect is observed when Reτ∗ increases towards the channel center. The present results provide an effective framework for categorizing turbulence modulation in wall-bounded flows with variable property effects, and can be applied to any Newtonian fluid that is heated or cooled.
A time domain based method for the accurate measurement of Q-factor and resonance frequency of microwave resonators

Published: September 2015

We present a novel method to determine the resonant frequency and quality factor of microwave resonators which is faster, more stable, and conceptually simpler than the yet existing techniques. The microwave resonator is pumped with the microwave radiation at a frequency away from its resonance. It then emits an exponentially decaying radiation at its eigen-frequency when the excitation is rapidly switched off. The emitted microwave signal is down-converted with a microwave mixer, digitized, and its Fourier transformation (FT) directly yields the resonance curve in a single shot. Being a FT based method, this technique possesses the Fellgett (multiplex) and Connes (accuracy) advantages and it conceptually mimics that of pulsed nuclear magnetic resonance. We also establish a novel benchmark to compare accuracy of the different approaches of microwave resonator measurements. This shows that the present method has similar accuracy to the existing ones, which are based on sweeping or modulating the frequency of the microwave radiation.

Strained InGaN/GaN core-shell nanowires (NWs) are promising candidates for solid state lighting applications due to their superior properties compared to planar films. NW based devices consist of multiple functional layers, which sum up to many hundred nanometers in thickness, that can uniquely be accessed in a non-destructive fashion by hard X-rays. Here, we present a detailed nanoscale strain mapping performed on a single, 400 nm thick and 2 μm long core-shell InGaN/GaN nanowire with an x-ray beam focused down to 100 nm. We observe an inhomogeneous strain distribution caused by the asymmetric strain relaxation in the shell. One side of the InGaN shell was fully strained, whereas the other side and the top part were relaxed. Additionally, tilt and strain gradients were determined at the interface with the substrate.

Published: September 2015

Two different templates (〈001〉 Ba6Ti17O40 and 〈111〉 BaTiO3) were used for synthesizing 〈111〉 textured tetragonal 0.6Pb(Mg1/3Nb2/3)O3-0.4PbTiO3(PMN-40PT) ceramics. It was found that a texture degree of 95% along 〈111〉 direction can be achieved by using only 1 vol. % 〈111〉 BaTiO3 template due to its high chemical stability in the PMN-40PT matrix. The textured PMN-40PT ceramics with tetragonal structure exhibited an excellent temperature stability of piezoelectric properties due to the absence of intermediate phase transitions between room temperature and the Curie temperature. Unlike the single crystal counterpart, the effect of 〈111〉 grain orientation in the textured PMN-40PT ceramic on enhancing the macroscopic piezoelectric response was not significant in spite of its giant local piezoresponse. We provide detailed discussions on the nature of piezoelectric response in the 〈111〉 textured tetragonal PMN-40PT ceramic with “3T” engineered domain configuration and resultant strategy to realize high performance piezoelectric ceramics.
A complete map of the ion chemistry of the naphthalene radical cation? DFT and RRKM modeling of a complex potential energy surface
Authors: Solano Eduardo A. , Mayer Paul M.
Published: September 2015

The fragmentation mechanisms of the naphthalene molecular ion to [M–C4H2]+•, [M–C2H2]+•, [M–H2]+•, and [M–H•]+ were obtained at the UB3LYP/6-311+G(3df,2p)//UB3LYP/6-31G(d) level of theory and were subsequently used to calculate the microcanonical rate constants, k(E)’s, for all the steps by the Rice-Ramsperger-Kassel-Marcus formalism. The pre-equilibrium and steady state approximations were applied on different regions of the potential energy profiles to obtain the fragmentation k(E)’s and calculate the relative abundances of the ions as a function of energy. These results reproduce acceptably well the imaging photoelectron-photoion coincidence spectra of naphthalene, in the photon-energy range 14.0–18.8 eV that was previously reported by our group. Prior to dissociation, the molecular ion rapidly equilibrates with a set of isomers that includes the Z- and E-phenylvinylacetylene (PVA) radical cations. The naphthalene ion is the predominant isomer below 10 eV internal energy, with the other isomers remaining at steady state concentrations. Later on, new steady-state intermediates are formed, such as the azulene and 1-phenyl-butatriene radical cations. The naphthalene ion does not eject an H atom directly but eliminates an H2 molecule in a two-step fragmentation. H• loss occurs instead from the 1-phenyl-butatriene ion. The PVA ions initiate the ejection of diacetylene (C4H2) to yield the benzene radical cation. Acetylene elimination yields the pentalene cation at low energies (where it can account for 45.9%–100.0% of the rate constant of this channel), in a three-step mechanism starting from the azulene ion. However, above 7.6 eV, the major [M–C2H2]+• structure is the phenylacetylene cation.
Orientational relaxation in free-standing smectic C film driven by rotating circular frame
Authors: Zakharov A. V. , Vakulenko A. A.
Published: September 2015

The pecularities in the cˆ-director reorientation in free-standing smectic C film without of defects and stretched between two circular frames, the rest outer and rotating inner, have been investigated theoretically based on the hydrodynamic theory including the cˆ-director motion and with accounting for backflow. Since the orientation of the cˆ-director is fixed at the rims of the smectic film, the shear flow induced by rotating frame winds up of the cˆ-director field. It is found that the higher shearing flow produces the greater twisting rotation of the cˆ-director around the normal to the smectic film directed in the opposite sense with respect to the direction of the angular velocity. Calculations also show that the relaxation dynamics of the cˆ-director field depends crucially on the curvature of the inner rotating frame.

Published: September 2015

In this study, we present a theoretical investigation of structural, electronic, and mechanical properties of pentagonal monolayers of carbon (p-graphene), boron nitride (p-B2N4 and p-B4N2), and silver azide (p-AgN3) by performing state-of-the-art first principles calculations. Our total energy calculations suggest feasible formation of monolayer crystal structures composed entirely of pentagons. In addition, electronic band dispersion calculations indicate that while p-graphene and p-AgN3 are semiconductors with indirect bandgaps, p-BN structures display metallic behavior. We also investigate the mechanical properties (in-plane stiffness and the Poisson's ratio) of four different pentagonal structures under uniaxial strain. p-graphene is found to have the highest stiffness value and the corresponding Poisson's ratio is found to be negative. Similarly, p-B2N4 and p-B4N2 have negative Poisson's ratio values. On the other hand, the p-AgN3 has a large and positive Poisson's ratio. In dynamical stability tests based on calculated phonon spectra of these pentagonal monolayers, we find that only p-graphene and p-B2N4 are stable, but p-AgN3 and p-B4N2 are vulnerable against vibrational excitations.
The radiation reaction effects in the ultra-intense and ultra-short laser foil interaction regime

Published: September 2015

The extreme laser intensity, IL>1023 W/cm2, will be made possible by Extreme Light Infrastructure. Such an ultra-intense and ultra-short laser pulse promises to promote laser-matter interaction into the exotic quantum-electro-dynamical regime. Electrons quivering in such a strong laser pulse experience a radiation reaction (RR) friction force by radiating high frequency photons. These extreme intensities will also make possible acceleration of heavy ions in new regimes. In this paper, the heavy ion beam generation based on ultra-intense and ultra-short laser foil interaction is systematically studied. Three-dimensional particle-in-cell simulations which include an energy conserving electrodynamics model for RR force and the corresponding γ-photons emission have been used. The energy partition into electrons, ions, and photons has been investigated in relation to efficient generation of heavy ion beams by linearly and circularly polarized (LP and CP) laser and for different foil thicknesses. It is found that the CP and LP cases each have an optimal foil thickness for efficient ion beam generation; the RR force has a stronger effect upon laser coupling to an opaque foil target for an LP laser than a CP laser; and the emitted photons are proven to be an efficient source of γ-ray emission with the peak frequency as high as 106∼108 times the laser frequency.
Chemical accuracy from quantum Monte Carlo for the benzene dimer
Authors: Azadi Sam , Cohen R. E.
Published: September 2015

We report an accurate study of interactions between benzene molecules using variational quantum Monte Carlo (VMC) and diffusion quantum Monte Carlo (DMC) methods. We compare these results with density functional theory using different van der Waals functionals. In our quantum Monte Carlo (QMC) calculations, we use accurate correlated trial wave functions including three-body Jastrow factors and backflow transformations. We consider two benzene molecules in the parallel displaced geometry, and find that by highly optimizing the wave function and introducing more dynamical correlation into the wave function, we compute the weak chemical binding energy between aromatic rings accurately. We find optimal VMC and DMC binding energies of −2.3(4) and −2.7(3) kcal/mol, respectively. The best estimate of the coupled-cluster theory through perturbative triplets/complete basis set limit is −2.65(2) kcal/mol [Miliordos et al., J. Phys. Chem. A 118, 7568 (2014)]. Our results indicate that QMC methods give chemical accuracy for weakly bound van der Waals molecular interactions, comparable to results from the best quantum chemistry methods.

We report on high-accuracy measurements of quantized current, sourced by a tunable-barrier single-electron pump at frequencies f up to 1 GHz. The measurements were performed with an ultrastable picoammeter instrument, traceable to the Josephson and quantum Hall effects. Current quantization according to I = ef with e being the elementary charge was confirmed at f = 545 MHz with a total relative uncertainty of 0.2 ppm, improving the state of the art by about a factor of 5. The accuracy of a possible future quantum current standard based on single-electron transport was experimentally validated to be better than the best (indirect) realization of the ampere within the present SI.

We report observation of strong light-matter coupling in an AlGaAs microcavity (MC) with an embedded single parabolic quantum well. The parabolic potential is achieved by varying aluminum concentration along the growth direction providing equally spaced energy levels, as confirmed by Brewster angle reflectivity from a reference sample without MC. It acts as an active region of the structure which potentially allows cascaded emission of terahertz (THz) light. Spectrally and time resolved pump-probe spectroscopy reveals characteristic quantum beats whose frequencies range from 0.9 to 4.5 THz, corresponding to energy separation between relevant excitonic levels. The structure exhibits strong stimulated nonlinear emission with simultaneous transition to weak coupling regime. The present study highlights the potential of such devices for creating cascaded relaxation of bosons, which could be utilized for THz emission.
