Abstract:
In this work, a facile two-step strategy is adopted to construct hierarchical polyaniline/NiCo-layered double hydroxide (PANI/NiCo-LDH) core-shell composite nanofiber networks on carbon cloth (CC). Three-dimensional (3D) porous PANI nanofiber networks are firstly uniformly anchored on CC by in-situ oxidative polymerization, followed by growth of NiCo-LDH nanoflakes on the crosslinked PANI framework via electrochemical deposition. The morphology and electrochemical properties of PANI/NiCo-LDH composites are controlled by the deposition time of LDH. Benefiting from rapid electron transport and ion diffusion, the well-defined PANI/NiCo-LDH hierarchical composite with 200 s deposition of LDH delivers a large capacitance of 1845 F g−1 at 0.5 A g−1 and excellent cycling stability of 82% capacitance retention after 5000 cycles at a very high current density of 10.0 A g−1. Furthermore, an asymmetric supercapacitor (ASC) assembled with PANI/NiCo-LDH as a positive electrode and activated carbon (AC) as a negative electrode exhibits a high capacitance of 147.2 F g−1 in a potential range from 0 to 1.5 V and superior energy density of 46.0 Wh kg−1 at a power density of 351.6 W kg−1.

Abstract:
Porous structure and surface defects are important to improve the performance of supercapacitors. In this study, a facile pathway was developed for high-performance supercapacitors, which can produce transition metal hydroxides (LDHs) with abundant porous structure and surface defects. The NiCo-SDBS-LDH was prepared by one-step hydrothermal reaction using sodium dodecylbenzene sulfonate (SDBS) as anionic surfactant. And then, three dimensional (3D) interconnected porous flower-like 3D-NiCo-SDBS-LDH microspheres were designed and synthesized using the gas-phase hydrazine hydrate reduction method. Results showed that the hydrazine hydrate reduction not only introduces a large number of pores into 3D-NiCo-SDBS-LDH microspheres and causes the formation of oxygen vacancies, but it also roughens the surface of the microspheres. All these changes contribute to the enhancement of electrochemical activity of 3D-NiCo-SDBS-LDH; the NiCo-SDBS-LDH electrode after hydrazine hydrate treatment (3D-NiCo-SDBS-LDH) exhibits a higher specific capacitance of 1148 F·g−1 at 1 A·g−1 (about 1.46 times larger than that of NiCo-SDBS-LDH) and excellent long cycle life with 94% retention after 4000 cycles. Moreover, the assembled 3D-NiCo-SDBS-LDH//AC (active carbon) asymmetric supercapacitor (ASC) achieves remarkable energy density of 73.14 W h·kg−1 at 800 W·kg−1 and long-term cycling stability of 95.5% retention for up to 10,000 cycles. The outstanding electrochemical performance can be attributed to the synergy between the rich porous structure and the roughened surface that has been created by the hydrazine hydrate treatment.

Abstract:
Layered double hydroxides (LDHs) are identified as potential material in water splitting or oxygen evolution reaction (OER). Since the water splitting potential is minimized when the use of LDH modified electrode, the application of the LDHs has been still challenged in air pollution control but the water splitting potential should be attempted to extended. Anions or cations intercalation has many applications in electrocatalysis and energy harvesting field. In this approach, the present work aimed to investigate a cyano-anion intercalation on NiCo-LDH and its application to degradation of acetaldehyde in gas phase. The NiCo-LDH was prepared using coprecipitation method under a low temperature. The prepared NiCo-LDH was intercalated with cyano-anion using KCN. After surface characterization to confirm the intercalation of cyano-anion, the NiCo-CN-LDH was coated on a 3D metal foam electrode using a 5% Nafion solution. Redox behavior of the prepared NiCo-CN-LDH electrode was observed in 1M KOH solution by cyclic voltammetry (CV) technique. Once identified the water splitting potential window, the NiCo-CN-LDH electrode was examined on the acetaldehyde (AA) reduction/oxidation in the 1M KOH solution. To evaluate the NiCo-CN-LDH electrode effect on AA, the potential truncated CV at various potential regions. After solution-phase CV analysis, the NiCo-CN-LDH electrode was fitted into Nafion membrane divided electrolytic flow through cell for the gas-phase degradation analysis either by anodic or cathodic half-cell. The NiCo-CN-LDH electrode’s redox behavior was analyzed and compared with solution phase redox behavior. Then the NiCo-CN-LDH electrode was applied on the AA degradation either by oxidation or reduction by continuous flow of AA gas. The degradation efficiency was monitored by ex-situ GC-MS. The promoted effect of cyano-anion on widening the water splitting potential window and its usage on gas phase AA degradation will be discussed in detail at the conference.

Abstract:
In this work, a novel three-dimensional (3D) hollow nickel-cobalt layered double hydroxide (NiCo-LDH) was synthesized using zeolitic imidazole framework-67 (ZIF-67) as a template, and then utilized to functionalize molybdenum disulfide (NiCo-LDH/MoS2) via electrostatic force. Flame retardant thermoplastic polyurethane (TPU) composites were prepared by the melt blending method. Compared to pure TPU, NiCo-LDH/MoS2 filled TPU composite was endowed with a decrease of 30.9% and 55.7% of the peak heat release rate (PHRR) and the peak smoke production rate (PSPR), respectively. Furthermore, the addition of NiCo-LDH/MoS2 can significantly improve the thermal stability and char yield of the TPU composite. The catalytic carbonization effect and dilution effect of NiCo-LDH, and the barrier effect of MoS2 nanosheets enable TPU composites with excellent flame retardancy and toxic gas suppression ability.

Abstract:
Proper control of a 3d transition metal-based catalyst with advanced structures toward oxygen evolution reaction (OER) with a more feasible synthesis strategy is of great significance for sustainable energy-related devices. Herein, carbon nanotube interconnected NiCo layered double hydroxide rhombic dodecahedral nanocages (NiCo-LDH RDC@CNTs) were developed here with the assistance of a feasible zeolitic imidazolate framework (ZIF) self-sacrificing template strategy as a highly efficient OER electrocatalyst. Profited by the well-fined rhombic dodecahedral nanocage architecture, CNTs’ interconnected characteristic and structural feature of the vertically aligned nanosheets, the as-synthesized NiCo-LDH RDC@CNTs integrated large exposed active surface areas, enhanced electron transfer capacity and multidimensional mass diffusion channels, and thereby collaboratively afforded the remarkable electrocatalytic performance of the OER. Specifically, the designed NiCo-LDH RDC@CNTs exhibited a distinguished OER activity, which only required a low overpotential of 255 mV to reach a current density of 10 mA cm−2 for the OER. For the stability, no obvious current attenuation was detected, even after continuous operation for more than 27 h. We certainly believe that the current extraordinary OER activity combined with the robust stability of NiCo-LDH RDC@CNTs enables it to be a great candidate electrocatalyst for economical and sustainable energy-related devices.

Abstract:
L’objectif de cette étude consiste à élaborer des couches d’oxydes qui seront utilisées dans des dispositifs fonctionnant à haute température. Les oxydes synthétisés répondent bien aux propriétés recherchées dans les piles à combustible à électrolyte solide et les barrières thermiques. Cet objectif a été atteint grâce à l’utilisation d’un plasma hors-équilibre généré dans un réacteur à tuyère convergente supersonique. Un aérosol contenant les précurseurs nitrés est introduit, à l’aide du système d’injection adapté, dans le réacteur plasma en vue d’obtenir les dépôts d’oxydes recherchés. La mise au point d’un nouveau système d’injection a rendu possible la réalisation des dépôts réputés difficiles à élaborer. L’étude hydrodynamique de l’écoulement des gaz et des particules dans le réacteur a été réalisée de deux façons. D’une part, le modèle développé sous FLUENT a indiqué que la vitesse des gaz plasmagènes en sortie de la tuyère peut atteindre 700 m. S-1. D’autre part, l’anémométrie laser-Doppler a montré le rôle important de la tuyère convergente qui accélère l’écoulement des particules. La spectroscopie d’émission optique a révélé l’importance de cette tuyère sur la concentration des espèces réactives dans le plasma et sa contribution sur la dissociation de l’eau par la présence des radicaux OH° et des H atomiques. Un code développé dans notre laboratoire a permis d’étudier l’évolution des fractions molaires des espèces réactives le long du réacteur en fonction de la puissance et du diamètre du col de la tuyère. La microscopie électronique à balayage a mis en évidence la morphologie des dépôts synthétisés. La spectrophotométrie infrarouge à transformée de Fourier a été employée pour quantifier l’influence des différents paramètres sur le taux de conversion des précurseurs en oxydes. La diffraction des rayons X a confirmé la pureté des dépôts et la structure cristalline correspondante<br>The objective of this study is the development of processes for the creation of oxide films to be used in devices which are designed to function at high temperature. Such synthetic oxides are well-suited toward applications in solid oxide fuel cells and thermal barriers. Non-equilibrium plasma generated in a reactor with a supersonic convergent nozzle was used for the deposition of the oxide films. A nitrated chemical precursor was introduced to the plasma reactor in aerosol form via an adapted injector system. This new aerosol injection system coupled with the plasma enabled the development of oxide layer types which are reputed to be technically difficult to obtain. Study of the fluid dynamics of the gas-particle system was done in two ways. First, a numerical simulation developed using the software FLUENT indicated that the velocity of the plasma exiting a convergent nozzle in the system may be as much as 700m/s. Second, laser-Doppler anemometry experiments showed the importance of the role of the convergent nozzle for gas/particle acceleration. Emission spectroscopic measurements showed the important effect of the convergent nozzle on the concentration of reactive species in the plasma and its contribution to the dissociation of water observed by the presence of OH radical and H bands. Software was developed permitting the study of the evolution of the molar fraction of reactive species along the reactor as a function of the plasma power and the diameter of the convergent nozzle. Scanning electron microscopy was used to study the morphology of the synthetic oxide deposits. Fourier transform infrared spectroscopy was used to quantify the influence of different parameters on the conversion yield. X-ray diffraction spectroscopy was used to measure the purity of the deposits and their corresponding crystal structures

Abstract:
Brachytherapy has been a popular topic for AAPM summer schools, with this marking the third time the subject has been covered (past schools on the topic were held in 1994 and 2005). This book was developed for the AAPM 2017 Summer School in Portland, Oregon, held in conjunction with the American Brachytherapy Association. From Joann Prisciandaro in Medical Physics…"Overall, this text is well written and provides a nice summary of current and developing clinical brachytherapy practice patterns. …from my perspective as a practicing brachytherapy physicist and educator, this text will make an extremely useful reference and will certainly be added to my list of required reading for residents and graduate students." This book is more than a comprehensive overview of the brachytherapy tools and techniques used in a modern clinic. The book also looks at numerous exciting approaches currently under development. Topics include HDR and LDR brachytherapy for the prostate, general planning and model-based dose calculation algorithms, intensity-modulated brachytherapy, electronic brachytherapy sources and techniques, and brachytherapy advances for treating skin, gynecological, and breast cancer. Some of the promising new techniques covered include focal therapy, the use of 3D printing to augment treatment, advances in needle tracking, in vivo dosimetry, and the use of robotics in brachytherapy.

Abstract:
A series of well crystallized Ni-Co-Zn-Al LDHs materials has been prepared by the urea hydrolysis method as precursors of mixed oxide catalysts for the Ethanol Steam Reforming (ESR) reaction. The calcination of the layered precursors gives rise to high surface area mixed oxides, mainly a mixture of rock-salt phase (NiO), wurtzite phase (ZnO) and spinel phase. Both precursors and mixed oxides have been throughtfully characterized and the steam reforming of ethanol has been investigated over the calcined catalysts in flow reactor and in-situ FT-IR experiments. The data here reported provide evidence of the good catalytic activity of Co-Zn-Al and Co-Ni-Zn-Al catalysts prepared from hydrotalcite-like LHD precursors for ethanol steam reforming. At 823 K the most active Co/Ni catalyst containains a predominant spinel phase with composition near Zn0.58Ni0.42[Al0.44Co0.56]2O4 and small amounts of NiO and ZnO. On the other side, at 873 K the selectivity to hydrogen increases with cobalt content. In particular, the presence of cobalt increases selectivity to H2 and CO2 and decreases selectivity to methane in the low temperature range 720–870 K. The most selective catalyst is the Ni-free Co-Zn-Al mixed oxide essentially constituted by a single spinel type phase Zn0.55Co0.45[Al0.45Co0.55]2O4. Cobalt catalysts appear consequently to behave better than nickel based catalysts in this temperature range. The key feature for high selectivity to hydrogen is proposed to be associated to a stability of a relatively high oxidation state at the catalyst surface, the most relevant selectivity determining step being constituted by the evolution of surface acetate species. In fact, over oxidized catalyst surface the acetate species evolve producing carbon dioxide and hydrogen while over a more reduced surface they evolve giving rise to methane and COx. Water is supposed to have the main role of allowing surface sites to stay in an unreduced state at least in the temperature range 720–870 K.

Abstract:
Abstract New developments in the field of thermal spraying systems (increased particle velocities, enhanced process stability) are leading to improved coating properties. At the same time innovations in the field of feedstock materials are supporting this trend. The combination of modern thermal spraying systems and new material concepts has led to a renaissance of Fe-based feedstocks. Using modern APS or HVOF systems, it is now possible to compete with classical materials for wear and corrosion applications like Ni basis (e.g. NiCrBSi) or metal matrix composites (MMC, e.g. WC/Co or Cr3C2/NiCr). The work described in this paper focuses on that combination and intends to give an analysis of the in-flight particle and spray jet properties achievable with two different modern thermal spraying systems (kerosene driven HVOF system K2, 3- cathodes APS system TriplexPro-200/-210) using Fe-based powders. The velocity fields are measured with the Laser Doppler Anemometry (LDA). Additionally, resulting coatings are analyzed metallographically with regard to their properties and a correlation with the particle in-flight properties is given. The experimental work is accompanied by computational fluid dynamics (CFD) simulations of spray jet and particle velocities, leading to a comprehensive analysis and characterization of the achievable particle properties with state-of-the-art HVOF and APS systems.
