Authors: Abdulrazzak Firas H. , Hussein Falah H. , Alkaim Ayad F. , Ivanova Irina , Emeline Alexei V. , Bahnemannd Detlef W.
Published: September 2016

Modified Pt-TiO2 NPs/decorated carbon nanotubes were synthesized utilizing sonochemical/hydration—dehydration techniques. Pt was loaded on TiO2 by a photodeposition method keeping in mind the end goal to achieve electron—hole pair separation and promote the surface reaction. The morphological and basic properties of Pt-TiO2/fCNTs were investigated by field emission scanning electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM), powder X-ray diffraction (XRD), UV—vis diffuse reflectance spectroscopy (DRS), photoluminescence (PL) and Raman spectroscopy. The selected area electron diffraction (SAED) patterns of Pt-TiO2/fCNTs were obtained utilizing TEM-based energy dispersive X-ray spectroscopy (EDXS) analysis. It was found that the TiO2 nanoparticles were uniformly distributed on the fCNTs, and the Pt particles were decorated on the surface of TiO2/fCNTs. The photocatalytic hydrogen production activity of the Pt(0.5%)-TiO2/fCNTs(0.5%) nanoparticle composites was investigated using a sacrificial agent methanol solution. Pt-loaded TiO2 demonstrated a hydrogen evolution rate around 20 times that of TiO2/fCNTs(0.5%) (fSWCNTs, fMWCNTs). When compared with platinized TiO2 in methanol, which was utilized as a control material, Pt-TiO2/fCNTs demonstrated an almost 2-fold increment in hydrogen generation.

Prepare, Do, Review: a model used to reduce the negative feelings towards laboratory classes in an introductory chemistry undergraduate unit
Authors: Spagnoli Dino , Wong Lawrence , Maisey Shannan , Clemons Tristan D.
Published: September 2016

Student feelings towards the laboratory component of an introductory chemistry unit were evaluated in an action research study, over a three-year period at the University of Western Australia. In 2013 we found that the percentage of students with negative feelings towards the laboratory increased over the duration of a semester. In 2014 we developed and introduced the use of pre-laboratory online activities, which the students found to be helpful in preparing them for the laboratory. However, there was no change in trend of negative feelings towards laboratory classes from 2013 to 2014. In 2015 we introduced the Prepare, Do, Review model and found that there was a reduction in the percentage of students with negative feelings towards laboratory classes compared with previous years. The Prepare, Do, Review model allows students more time to process the information given in the laboratory. We believe that this model could apply to laboratory programs in any discipline.

Iterative conjugate heat transfer analysis for heat transfer enhancement of an externally cooled three‐phase induction motor
Authors: Tiwari Ankit , Yavuzkurt Savas
Published: September 2016

A novel iterative conjugate heat transfer method is proposed for thermal modelling of a drill pump motor which is a constant speed three‐phase induction motor. The major advantage of this technique is that it enables computational fluid dynamics (CFD) and heat transfer analysis of the rotor and the stator in a segregated manner. The two are then coupled in a separate annulus model, which represents the air gap, via boundary conditions on the annulus walls. This greatly reduces the total number of computational cells and enables good quality mesh generation – a pre‐requisite for accurate CFD predictions. To validate this method, a baseline CFD and heat transfer analysis was done using FLUENT and the maximum temperature prediction was found to be within 1.75% of the previously done experiments on the existing design of the machine. Further, this method was applied to develop a heat transfer enhancement solution which reduced the maximum temperature in the drill motor from 203.5 °C to 172.9 °C.
Improvement of power generation performance in a doubly salient permanent magnet generator with a capacitive energy recovery converter
Authors: Qiji Ze , Liang Deliang , Kou Peng , Yu Yanan
Published: September 2016

In order to improve the power generation performance of a doubly salient permanent magnet generator (DSPMG), this study proposes a new converter called capacitive energy recovery converter (CERC), together with the corresponding control strategy. The CERC is composed of controllable devices, uncontrollable devices, and an energy storage circuit. The control strategy has been designed based on analysis of the electromagnetic characteristics of the DSPMG. With the proposed control strategy, the winding current of each phase can be controlled and increased separately, thus yielding large negative electromagnetic torque against the prime mover in a complete electric cycle. At the same time, the excitation sources are independent of the load part. As a result, power generation performance of the DSPMG with CERC is improved compared to that with a traditional three‐phase full‐bridge converter. A multi‐objective optimisation problem is formulated to find the optimal turn‐on and turn‐off angles of two systems, which are used as control parameters in this comparison. Besides the lower voltage and torque ripples, the dynamic and fault‐tolerant performance of the DSPMG with CERC is also superior. Both simulations and experiments have been conducted to verify the validity of the proposed converter and the control strategy.
Minimally Invasive Direct Lateral Corpectomy of the Thoracolumbar Spine for Metastatic Spinal Cord Compression
Authors: Tan Terence , Chu Jocelyn , Thien Christopher , Wang Yi
Published: September 2016

Objectives To evaluate the feasibility, safety, clinical, and radiologic outcomes of a minimally invasive direct lateral-approach corpectomy (MIDLaC) for decompression and stabilization of symptomatic metastatic spinal cord compression (MSCC).

Methods A retrospective study on a prospective cohort was conducted. Nineteen patients were consecutively treated with MIDLaC and posterior pedicle screw fixation between May 2012 and July 2014. Demographic information and radiologic outcomes including sagittal deformity correction and vertebral body height were recorded. Operative variables (operative duration, blood loss) and clinical variables (Tokuhashi score, mortality, complication rate, pain visual analogue scale [VAS], opioid usage, and Frankel grade) were recorded and analyzed.

Results All nineteen patients (mean age: 67.6 ± 12.7 years) successfully underwent MIDLaC with excellent neural decompression. Operative duration was 188.4 ± 30.3 minutes for single-level MIDLaC and 327.2 ± 71.9 minutes for multilevel surgery (p < 0.0001). Mean blood loss per spinal level was 390.8 mL with a decrease to 102.3 mL excluding renal cell MSCC. A total of 47.4% of patients had a Tokuhashi score of 0 to 8. There was one approach-related complication and one perioperative mortality. The overall complication rate was 15.8% (n = 3) with no postoperative wound infections. Kaplan-Meier survival estimates at 6 months were 0.50. Overall, 31.6% of patients improved by one or more Frankel grades, and no patients demonstrated worsening neurology postoperatively. VAS was significantly improved postoperatively (p < 0.05). Vertebral body height was significantly increased (+7.6 ± 8.1 mm; p = 0.002), with improvements in lumbar lordosis (8.3 ± 7.3 degrees) and thoracic kyphosis (2.4 ± 7.1 degrees) postoperatively.

Conclusion MIDLaC is a safe and feasible palliative approach in the management of MSCC with encouraging early clinical outcomes. Further prospective studies are required to define the role of MIDLaC in the management of MSCC vis-à-vis other mini-open or minimally invasive techniques.
Leading edge reflection patterns for cylindrical converging shock waves over convex obstacles
Authors: Vignati F. , Guardone A.
Published: September 2016

The unsteady reflection of cylindrical converging shock waves over convex obstacles is investigated numerically. At the leading edge, numerical simulations show the occurrence of all types of regular and irregular reflections predicted by the pseudo-steady theory for planar shock-wave reflections over planar surfaces, although for different combinations of wedge angles and incident shock Mach number. The domain of occurrence of each reflection type and its evolution in time due to shock acceleration and to the non-planar geometry is determined and it is compared to the results of the pseudo-steady theory. The dependence of the reflection pattern on the (local) values of the wedge angle is in good agreement with the pseudo-steady theory. Less complex reflection patterns are instead observed at larger values of the leading edge shock Mach number at which the pseudo-steady theory predicts the occurrence of more complex reflection patterns.

Bulk ion toroidal velocity profiles, V||D+, peaking at 40–60 km/s are observed with Mach probes in a narrow edge region of DIII-D discharges without external momentum input. This intrinsic rotation can be well reproduced by a first principle, collisionless kinetic loss model of thermal ion loss that predicts the existence of a loss-cone distribution in velocity space resulting in a co-Ip directed velocity. We consider two kinetic models, one of which includes turbulence-enhanced momentum transport, as well as the Pfirsch-Schluter (P-S) fluid mechanism. We measure a fine structure of the boundary radial electric field, Er, insofar ignored, featuring large (10–20 kV/m) positive peaks in the scrape off layer (SOL) at, or slightly inside, the last closed flux surface of these low power L- and H-mode discharges in DIII-D. The Er structure significantly affects the ion-loss model, extended to account for a non-uniform electric field. We also find that V||D+ is reduced when the magnetic topology is changed from lower single null to upper single null. The kinetic ion loss model containing turbulence-enhanced momentum transport can explain the reduction, as we find that the potential fluctuations decay with radius, while we need to invoke a topology-enhanced collisionality on the simpler kinetic model. The P-S mechanism fails to reproduce the damping. We show a clear correlation between the near core V||C6+ velocity and the peak edge V||D+ in discharges with no external torque, further supporting the hypothesis that ion loss is the source for intrinsic torque in the present tokamaks. However, we also show that when external torque is injected in the core, it can complete with, and eventually overwhelm, the edge source, thus determining the near SOL flows. Finally, we show some additional evidence that the ion/electron distribution in the SOL is non-Maxwellian.
Predominance of short range Coulomb forces in phosphate-water interactions—a theoretical analysis
Authors: Fingerhut Benjamin P. , Costard Rene , Elsaesser Thomas
Published: September 2016

Electric forces play a key role in the interaction of negatively charged phosphate groups with the dipolar water molecules of an aqueous environment. Both fluctuation amplitudes and effective spatial range of the electric fields that fluctuate on a multitude of time scales have remained highly controversial. We employ the dimethylphosphate anion (DMP) as a fundamental building block of the phosphodiester backbone in DNA to model electric fields at the phosphate-water interface. DMP is considered to be solvated in bulk water and the fluctuating electric forces exerted on the (PO2)− moiety are calculated by combining the ab initio based effective fragment potential approach that accounts for electric fields due to static multipoles and polarization contributions due to induced dipoles, with molecular dynamics. We demonstrate that the total time-averaged electric field generated by water molecules arises to a large extent from the first water layer. The second layer contributes some 18% with noticeable contributions from induction. We further show that the solvent electric field experienced by the phosphate group is the dominant contribution to the pronounced solvatochromism of the asymmetric (PO2)− stretch vibration. Accounting for a field expansion up to quadrupoles and polarization due to induced dipoles allows us to simulate solvent induced frequency shifts and lineshapes in almost quantitative agreement to experiment. Our theoretical model strongly supports the picture of short-range electric forces that arise locally from the first and second hydration shell.
Evidence for two distinct defect related luminescence features in monolayer MoS2
Authors: Saigal Nihit , Ghosh Sandip
Published: September 2016

Apart from the defect related emission peak which lies ∼100 meV below the A exciton/trion peak and is labeled D1 here, this study shows that there is another distinct feature D2 lying ∼200 meV below A in the photoluminescence spectrum of the exfoliated monolayer MoS2 on SiO2/Si substrates. The D2 feature is explicitly resolved at low temperature only in few samples. Both D1 and D2 do not show circular polarization anisotropy for 633 nm excitation. Both decay with the increase in temperature in a seemingly activated manner with similar activation energy of ∼50 meV, but D1 decays earlier and therefore D2 dominates at high temperature in all samples. Annealing in vacuum increases both D1 and D2 emission intensities while annealing under sulfur vapour decreases them. Comparison with reported theoretical studies on defects in monolayer MoS2 suggests that these two emissions possibly involve excitons bound to single and double sulphur vacancies, the latter binding excitons more strongly.
Laser-projected photothermal thermography using thermal wave field interference for subsurface defect characterization
Authors: Thiel Erik , Kreutzbruck Marc , Ziegler Mathias
Published: September 2016

The coherent superposition of two anti-phased thermal wave fields creates a zone of destructive interference which is extremely sensitive to the presence of defects without any reference measurements. Combining a high power laser with a spatial light modulator allows modulating phase and amplitude of an illuminated surface that induces spatially and temporally controlled thermal wave fields. The position and depth of defects are reconstructed from analysis of the amplitude and phase of the resulting photothermal signal. The proposed concept is experimentally validated and supported by numerical modeling.
Predictive control of power flow between two islanded microgrids using nine-switch converter
Authors: Lee Sze Sing , Heng Yeh En
Published: September 2016

Nine-switch converter has been recently known for its higher compactness with reduced switch count as compared to the back-to-back converter. The readily available dc-link capacitor made it an appropriate alternative for ac/dc/ac conversion in microgrids. Regardless of the complicated Pulse Width Modulation control scheme, this paper proposes a novel predictive power control for the nine-switch converter which is simple and allows concurrent control of real and reactive power flow between two islanded microgrids. The proposed control scheme adopts the virtual flux vectors and a newly defined reactive power to improve the power quality under the existence of grid voltage disturbances, i.e., voltage unbalance and voltage distortion. Simulation results of the proposed predictive power control guarantee decoupled active and reactive power controls, fast response, accurate power and dc-link voltage tracking, and sinusoidal current waveforms with low harmonic distortions under the various grid conditions.
Stress relaxation in pulsed DC electromigration measurements
Authors: Ringler I. J. , Lloyd J. R.
Published: September 2016

When a high current density is applied to a conductor, it activates several driving forces for mass transport that can lead to device failure, the most prominent of which is electromigration. However, there are other driving forces operating as well that can counteract or add to the effects of electromigration. A major driving force is a stress gradient that is developed as a response to electromigration in the presence of a blocking boundary condition. When the electrical stress is interrupted by pulsing DC measurements at low frequency, relaxation of the stress is observed through longer lifetime.
Lygeum spartum L.: a review of a candidate for West Mediterranean arid rangeland rehabilitation
Authors: Nedjimi Bouzid
Published: September 2016

Lygeum spartum L. (Poaceae) is a perennial native grass grown throughout arid and semi-arid regions around the West Mediterranean basin. In terms of pastoral use, its associations with other annual species and small chamaephytes constitute a valuable source of livestock forage. L. spartum, which has an extensive root system, reduces soil erosion and enhances soil stabilisation. The leaves contain many fibres, producing a material suitable for basket manufacture. This plant species can also be used in the phytoremediation of contaminated soils. Published work on the research and development of this species is meagre. This article represents an effort to compile the literature on L. spartum and to review the current understanding of this plant and its potential as an alternative source of fodder during periods of forage scarcity, for traditional craftsmen, for phytoremediation and for rangeland rehabilitation purposes.
Recovery and adaptation after wildfire on the Colorado Front Range (2010–12)
Authors: Mockrin Miranda H. , Stewart Susan I. , Radeloff Volker C. , Hammer Roger B.
Published: September 2016

Following the loss of homes to wildfire, when risk has been made apparent, homeowners must decide whether to rebuild, and choose materials and vegetation, while local governments guide recovery and rebuilding. As wildfires are smaller and more localised than other disasters, it is unclear if recovery after wildfire results in policy change and adaptation, decreasing assets at risk, or if recovery encourages reinvestment in hazard-prone areas. We studied three wildfires on the Colorado Front Range from 2010 to 2012 that each destroyed over 150 homes, describing policy response and characterising the built environment after wildfire. In each location, we found some adaptation, through better-mitigated homes and stronger building and vegetation mitigation standards, but also extensive reinvestment in hazard-prone environments, with governmental support. Despite suggestions that disaster can lead to substantial policy change and elevate the role of land-use planning, we saw only modest reforms: local governments did not revise land-use regulations; a statewide task force considered but did not require standards for building and vegetation mitigation; and only one jurisdiction strengthened its building and vegetation mitigation standards. Experiences in Colorado suggest that time after wildfire either does not provide extensive opportunities for adaptation in the built environment, or that these opportunities are easily missed.

Significance

Plants detect conserved molecular patterns of pathogens via cell surface-localized receptors, such as the flagellin receptor kinase FLS2, that initiate effective plant immunity. Activated FLS2 is endocytosed, but the degree to which other receptor kinases exhibit similar spatiotemporal dynamics remains unclear. We show that internalization into a common endosomal pathway after ligand perception is a general phenomenon of the tested receptor kinases, including the danger peptide receptor PEPR1. FLS2 endocytosis is mediated by clathrin and is uncoupled from the regulation of acute pathogen-induced responses, but is involved in steady defenses and contributes to plant immunity against bacterial infection. We propose that clathrin-dependent internalization of ligand-activated receptor kinases into a common endosomal pathway facilitates the responses required for full plant immunity.
Single-cell dynamics and variability of MAPK activity in a yeast differentiation pathway
Authors: Conlon Patrick , Gelin-Licht Rita , Ganesan Ambhighainath , Zhang Jin , Levchenko Andre
Published: September 2016

Significance

The yeast mating pathway has long served as a prototypical signal transduction system, but key questions regarding intracellular signaling dynamics remain, including how signaling takes place and is used over time during the differentiation response. Utilizing a single-cell FRET reporter approach, this study indicates that signaling dynamics is governed by complex feedback interactions and that distinct MAPK activity patterns promote early and late phases of mating differently. Whereas submaximal activity is maintained through cell-cycle arrest and mating partner engagement, activity intensification and rapid loss coincide with cell polarization and fusion of prezygote cells. These findings provide new insights into the signaling mechanisms underlying how yeast cells sense and then commit to a nearby mating partner.
Key role for neutrophils in radiation-induced antitumor immune responses: Potentiation with G-CSF

Published: September 2016

Significance

The role of tumor-associated neutrophils (TANs) in cancer progression versus regression remains controversial. TANs are known to have dichotomous antitumor (N1) and protumor (N2) phenotypes depending on the tumor microenvironment. Past studies have demonstrated that TANs are polarized from an N2 to an N1 phenotype in the absence of TGF-β; N1 TANs are not induced in the absence of IFN-β. Our study demonstrates that radiation therapy (RT) and, especially, the combination of RT and granulocyte colony-stimulating factor (G-CSF) induces the polarization of N1 TANs [RT-recruited TANs (RT-Ns)]. Reactive oxygen species produced by RT-Ns damage tumor tissues in a manner analogous to the manner in which neutrophils affect damaged normal tissues. Our studies suggest that enhancing the activity of TANs during RT improves its antitumor activity.
