Energy harvesting from aperiodic low-frequency motion using reverse electrowetting
Authors: Hsu Tsung-Hsing , Taylor J. A. , Krupenkin T. N.
Published: January 2017

Mechanical energy harvesting can provide a promising alternative to electrochemical batteries, which are currently widely utilized to power mobile electronics. In this work we present a theoretical analysis of a recently proposed method of mechanical energy harvesting, which combines a reverse electrowetting phenomenon with the fast self-oscillating process of bubble growth and collapse. We investigate the details of the bubble dynamics and analyze the dependence of the energy generation process on the system parameters. The results demonstrate that self-oscillation frequencies of several kHz are possible, which can lead to very high power generation densities in excess of 104 W m−2. The obtained results indicate the possibility of high-power energy harvesting from mechanical energy sources with very low frequencies, well below 1 Hz.

Teachers’ views on implementing storytelling as a way to motivate inquiry learning in high-school chemistry teaching
Authors: Peleg Ran , Yayon Malka , Katchevich Dvora , Mamlok-Naaman Rachel , Fortus David , Eilks Ingo , Hofstein Avi
Published: January 2017

Educational research and policy suggest inquiry as one of the most prominent ways of promoting effective science education. However, traditional approaches towards inquiry learning are not always sufficiently motivating for all learners. The EU-funded project, TEMI – Teaching Enquiry with Mysteries Incorporated, suggests that mysterious scientific phenomena introducedviadrama-based pedagogies and showmanship skills could have the potential to engage more students emotionally in science and to entice them to solve the mysteries through inquiry. This paper reports teachers’ views on using storytelling in connection with mysteries in the science classroom. The data stem from a case of chemistry teachers’ continuous professional development within the TEMI project in Israel. Data were collected from 14 teachers by means of a questionnaire, interviews, observations, and written reflection essays. The case discusses teachers’ views on the benefits and difficulties of using story-based science inquiry activities.

Ectopic Molar Removal from the Ramus/Condyle Unit: A Minimally Invasive Approach
Authors: Forgach Gary A. , MacLeod Stephen P.R.
Published: January 2017

Ectopic molars within the mandibular ramus/condyle unit, although rare, present a unique challenge to the surgeon. Multiple approaches have been described in the literature for their removal. A review of the English literature on the subject of mandibular ectopic molars and their epidemiology, etiology, indications for removal, and surgical techniques was completed. In addition, a case report is presented of an ectopic mandibular molar in the mid-ramus region which was removed via a minimally invasive, intraoral, technique combining the use of endoscopy and piezoelectric surgery. The authors advocate this technique as it offers the following advantages: avoidance of injury to branches of the facial nerve, unaesthetic scars, and sialocele formation; maximization of surgical field visualization with limited dissection; ability for safe sectioning of the tooth with minimal risks to adjacent structures; and precise bone removal, reducing the risk of iatrogenic or postoperative mandible fracture.
No Clamp Complete Parachute Technique for Ascending Aorta Anastomosis in Hybrid Aortic Arch Debranching Surgery
Authors: Chen I-Ming , Chen Po-Lin , Chang Hsiao-Huang
Published: January 2017

The proper proximal landing zone is a key element for success of endografting in thoracic aortic pathology. If coverage of innominate artery is unavoidable for safe proximal landing, arch debranching surgery is necessary to recruit supra-aortic blood flow before endografting. However, calcified or adhesive ascending aorta makes it difficult to clamp ascending aorta for anastomosis in the first step of arch debranching surgery. We present a novel “no clamp complete parachute technique” to complete this challenging anastomosis.
Finite-time synchronization for recurrent neural networks with discontinuous activations and time-varying delays
Authors: Duan Lian , Huang Lihong , Fang Xianwen
Published: January 2017

In this paper, we study the finite-time synchronization problem for recurrent neural networks with discontinuous activations and time-varying delays. Based on the finite-time convergence theory and by using the nonsmooth analysis technique, some finite-time synchronization criteria for the considered neural network model are established, which are new and complement some existing ones. The feasibility and effectiveness of the proposed synchronization method are supported by two examples with numerical simulations.
Continuous time of flight measurements in a Lissajous configuration
Authors: Dobos G. , Hárs G.
Published: January 2017

Short pulses used by traditional time-of-flight mass spectrometers limit their duty cycle, pose space-charge issues, and require high speed detectors and electronics. The motivation behind the invention of continuous time of flight mass spectrometers was to mitigate these problems, by increasing the number of ions reaching the detector and eliminating the need for fast data acquisition systems. The most crucial components of these spectrometers are their modulators: they determine both the maximal modulation frequency and the modulation depth. Through these parameters they limit the achievable mass resolution and signal-to-noise ratio. In this paper, a new kind of setup is presented which modulates the beam by deflecting it in two perpendicular directions and collects ions on a position sensitive detector. Such an Lissajous time of flight spectrometer achieves modulation without the use of slits or apertures, making it possible for all ions to reach the detector, thereby increasing the transmission and signal-to-noise ratio. In this paper, we provide the mathematical description of the system, discuss its properties, and present a practical demonstration of the principle.
Initial mechanisms for the unimolecular decomposition of electronically excited bisfuroxan based energetic materials
Authors: Yuan Bing , Bernstein Elliot R.
Published: January 2017

Unimolecular decomposition of energetic molecules, 3,3′-diamino-4,4′-bisfuroxan (labeled as A) and 4,4′-diamino-3,3′-bisfuroxan (labeled as B), has been explored via 226/236 nm single photon laser excitation/decomposition. These two energetic molecules, subsequent to UV excitation, create NO as an initial decomposition product at the nanosecond excitation energies (5.0–5.5 eV) with warm vibrational temperature (1170 ± 50 K for A, 1400 ± 50 K for B) and cold rotational temperature (<55 K). Initial decomposition mechanisms for these two electronically excited, isolated molecules are explored at the complete active space self-consistent field (CASSCF(12,12)/6-31G(d)) level with and without MP2 correction. Potential energy surface calculations illustrate that conical intersections play an essential role in the calculated decomposition mechanisms. Based on experimental observations and theoretical calculations, NO product is released through opening of the furoxan ring: ring opening can occur either on the S1 excited or S0 ground electronic state. The reaction path with the lowest energetic barrier is that for which the furoxan ring opens on the S1 state via the breaking of the N1—O1 bond. Subsequently, the molecule moves to the ground S0 state through related ring-opening conical intersections, and an NO product is formed on the ground state surface with little rotational excitation at the last NO dissociation step. For the ground state ring opening decomposition mechanism, the N—O bond and C—N bond break together in order to generate dissociated NO. With the MP2 correction for the CASSCF(12,12) surface, the potential energies of molecules with dissociated NO product are in the range from 2.04 to 3.14 eV, close to the theoretical result for the density functional theory (B3LYP) and MP2 methods. The CASMP2(12,12) corrected approach is essential in order to obtain a reasonable potential energy surface that corresponds to the observed decomposition behavior of these molecules. Apparently, highly excited states are essential for an accurate representation of the kinetics and dynamics of excited state decomposition of both of these bisfuroxan energetic molecules. The experimental vibrational temperatures of NO products of A and B are about 800–1000 K lower than previously studied energetic molecules with NO as a decomposition product.
Tutorial: Physics and modeling of Hall thrusters
Authors: Boeuf Jean-Pierre
Published: January 2017

Hall thrusters are very efficient and competitive electric propulsion devices for satellites and are currently in use in a number of telecommunications and government spacecraft. Their power spans from 100 W to 20 kW, with thrust between a few mN and 1 N and specific impulse values between 1000 and 3000 s. The basic idea of Hall thrusters consists in generating a large local electric field in a plasma by using a transverse magnetic field to reduce the electron conductivity. This electric field can extract positive ions from the plasma and accelerate them to high velocity without extracting grids, providing the thrust. These principles are simple in appearance but the physics of Hall thrusters is very intricate and non-linear because of the complex electron transport across the magnetic field and its coupling with the electric field and the neutral atom density. This paper describes the basic physics of Hall thrusters and gives a (non-exhaustive) summary of the research efforts that have been devoted to the modelling and understanding of these devices in the last 20 years. Although the predictive capabilities of the models are still not sufficient for a full computer aided design of Hall thrusters, significant progress has been made in the qualitative and quantitative understanding of these devices.
Macroscopic motion of sheath-connected blobs in magnetic fields with arbitrary topology
Authors: Stepanenko A. A. , Lee W. , Krasheninnikov S. I.
Published: January 2017

In this study, macroscopic motion of sheath-connected blobs in magnetic fields, having arbitrary topology of the field lines and unfrozen in plasma, is analyzed within the electrostatic limit. Two distinct cases of magnetic configurations, with small and large curvature of the field lines, are considered and the criterion to discern them is deduced. For magnetic configurations with small curvature of the field lines, it is demonstrated that asymmetry of plasma distribution at the blob ends can drive macroscopic motion of a filament due to formation of unequal sheath potentials and establishing the effective Boltzmann potential. For a specific case of magnetic fields with small curvature of the field lines and identical metrics at the sheaths, we show that macroscopic motion of a plasma filament is determined by an effective electrostatic potential, which remains constant in time. For magnetic configurations with large curvature of the field lines, it is shown that motion of sufficiently large blobs is governed by integral distribution of plasma and magnetic field parameters along the field lines leading to blob adjusting its shape and position to the lead of the magnetic field lines in the course of its motion, whereas propagation of small and medium sized blobs can be represented as mutually independent motion of filament transverse cross-sections across the magnetic field lines. The qualitative conclusions on regularities of filament motion are supplied with numerical simulations of blob dynamics in two cases of tokamak-like magnetic fields with sheared and non-sheared field lines.
