Published: September 2017

Now a days telecommunication technology leads to a rapid growth of number of users, these number of users nothing but number of nodes in MANET.A wireless ad hoc network is a decentralized type of wireless network. The mobility of nodes effect on the performance of the network. Due to mobility of nodes the link breaks number of times which effect on the packet delivery. Therefore to analyze the performance, packet delivery fraction (PDF)can be used. This paper describe the packet delivery fraction of on demand routing protocol AODV and DSR on different terrain areas using GLOMOSIM.

Voleibol sentado: un deporte que da sentido a la vida
Authors: Muñoz Galíndez Efraín , Montes Mora Sandra
Published: September 2017

Este artículo es el resultado de una investigación que tuvo como objetivo interpretar el sentido que un grupo de deportistas de voleibol sentado le dan a este deporte. Las personas que permitieron el desarrollo de este estudio son ex-militares que en su quehacer profesional perdieron una de sus extremidades a manos de las minas antipersonas, sembradas por grupos al margen de la ley. Para ahondar en la subjetividad de los deportistas y develar sus sentires, se utilizó el enfoque cualitativo y como técnicas de recolección de datos la entrevista en profundidad y el grupo focal; los relatos fueron analizados y categorizados bajo la técnica de análisis de contenido y los lineamientos de la teoría fundada. Los resultados evidencian que la amputación es un episodio que cambió sus vidas sumergiéndolos en un mundo de incertidumbres, desafíos y retos que debieron sortear junto con sus familiares y personas allegadas. En este duelo las víctimas encontraron en el voleibol sentado un espacio para reencontrase con ellos mismos y sus pares, dándole nuevamente un sentido a sus vidas. Por ello, conciben el equipo de voleibol como una familia que les ha enseñado que los límites van más allá de la condición física.

Representation and Salary Gaps by Race-Ethnicity and Gender at Selective Public Universities
Authors: Li Diyi , Koedel Cory
Published: September 2017

We use data from 2015–2016 to document faculty representation and wage gaps by race-ethnicity and gender in six fields at selective public universities. Consistent with widely available information, Black, Hispanic, and female professors are underrepresented and White and Asian professors are overrepresented in our data. Disadvantaged minority and female underrepresentation is driven predominantly by underrepresentation in science and math intensive fields. A comparison of senior and junior faculty suggests a trend toward greater diversity, especially in science and math intensive fields, because younger faculty are more diverse. However, Black faculty are an exception. We decompose racial-ethnic and gender wage gaps and show that academic field, experience, and research productivity account for most or all of the gaps. We find no evidence of wage premiums for individuals who improve diversity, although for Black faculty we cannot rule out a modest premium.
The Design of Cluster Randomized Trials With Random Cross-Classifications
Authors: Moerbeek Mirjam , Safarkhani Maryam
Published: September 2017

Data from cluster randomized trials do not always have a pure hierarchical structure. For instance, students are nested within schools that may be crossed by neighborhoods, and soldiers are nested within army units that may be crossed by mental health–care professionals. It is important that the random cross-classification is taken into account while planning a cluster randomized trial. This article presents sample size equations, such that a desired power level is achieved for the test on treatment effect. Furthermore, it also presents optimal sample sizes given a budgetary constraint, with a special focus on conditional optimal designs where one of the sample sizes is fixed beforehand. The optimal design methodology is illustrated using a postdeployment training to reduce ill-health in armed forces personnel.

Im folgenden Beitrag wird eine Methode zur Kosten-Nutzen-Analyse beschrieben, die es erlaubt, fallspezifisch zu einer monetären Bewertung von IT-Investitionen in der Produktion zu gelangen. Ihre Realisierung in Software und Anwendung wird exemplarisch dargelegt.
Steigerung der Wettbewerbs-fähigkeit und Menschzentrierung stehen nicht im Widerspruch
Authors: Herkommer Oliver , Kleinbeck Thomas , Nitsche Jens
Published: September 2017

Kurzfassung

Im Rahmen des vom BMBF geförderten Projekts MyCPS wurden 383 Anwendungsfälle ausgewertet, in denen der „Menschbezug“ im Fokus stand. Nach der halben Projektlaufzeit endgültige Folgerungen in den Raum zu stellen, wäre zwar leichtfertig. Dennoch deuten die bisherigen Erkenntnisse darauf hin, dass ein Ergebnis dieses Förderprojekts lauten könnte: Im Vordergrund steht die Wettbewerbsfähigkeit der Unternehmen – der Nutzen für den Menschen rückt weniger deutlich in den Mittelpunkt, als man das am Ausgangspunkt der sogenannten Vierten Industriellen Revolution wahrhaben wollte. Immerhin 39 Prozent der von der Ingenics AG untersuchten 383 „Fälle“ beschreiben eine kooperative Interaktion mit den Mitarbeitern; 19 Prozent nennen die Substituierung menschlicher Arbeitsplätze als Ziel. Für Fachleute nicht überraschend kommt die Feststellung, dass Lean-Strukturen unverzichtbare „Enabler“ für die erfolgreiche Implementierung von Industrie-4.0-Anwendungen sind.
Constructing a Database for Computable General Equilibrium Modeling of Sydney, Australia, Transport Network
Authors: Robson Edward , Dixit Vinayak V.
Published: September 2017

In the search for benefits to justify transport projects, economic appraisals have increasingly incorporated the valuation of impacts to the wider economy. Computable general equilibrium (CGE) models provide a framework to estimate these impacts by simulating the interactions of urban economies and transport networks. In CGE models, households and firms are represented by microeconomic behavioral functions, and markets adjust according to prices. As markets both inside and outside the transport network are taken into account, a wide variety of measures that can assist in economic appraisals can be extracted. However, urban CGE models are computationally burdensome and require detailed, spatially disaggregate data. This paper discusses the methodology used to develop a database, including an input–output table, for the calibration of an urban CGE model for Sydney, Australia. Official and publicly available data sources were manipulated by using a number of mathematical and statistical techniques to compile a table for 249 regions and 20 sectors across Sydney. Issues, such as determining the appropriate level of aggregation, generating incomplete data, and managing conflicting data, that other input–output table developers may encounter when constructing multiregional tables were addressed in the study. The table entries themselves were mapped and explored, as they provide a useful study of the spatial economy of Sydney. Future work will focus on streamlining the construction of input–output tables and incorporating new data sources.
Relationship between Agglomeration and Productivity in a Norwegian Context
Authors: Nilsen Øyvind Lervik , Babri Sahar , Andersen Stig Nyland , Tørset Trude
Published: September 2017

Cost–benefit analysis (CBA) is an important tool in many countries in the evaluation of transport investments. The main objective of CBA is to allocate society's shared resources by considering all costs and benefits to society as a whole. While direct costs and benefits are often straightforward to calculate, indirect costs and benefits are more challenging to include in a CBA. In relation to indirect benefits, increased attention has been paid to potential productivity benefits for firms that result from reductions in distance to other firms, workers, or customers. The literature on wider economic impacts and agglomeration economies suggests that such benefits usually exist but vary between sectors and nations. However, little consensus seems to exist on the size of the benefits. This paper analyzes the relationship between agglomeration, productivity, and transport investment in a Norwegian context. A total factor productivity approach was used to calculate productivity for 17,000 firms along the western coast of Norway in eight sectors from 2009 to 2013. For each firm, an agglomeration index was calculated, and a regression model was used to find the relationship between productivity and agglomeration. The results show that productivity varied between sectors and that no clear trend occurred across all sectors to show that increased agglomeration leads to increased productivity. The implications of these results in a CBA perspective is that care should be taken in seeing agglomeration as solely beneficial for all sectors and be more specific in relation to which sectors are affected in each transport investment project.
The Value of Travel Time and Reliability: Empirical Evidence from Katy Freeway
Authors: Abir A. K. M. , Burris Mark W. , Spiegelman Clifford
Published: September 2017

Travelers place value on both time savings and reliability when choosing a route for a trip. The value of travel time (VOT) has long been an integral part of the appraisal of transport projects. Recently, some transport planners have been incorporating the value of travel time reliability (VOR) as well. This research used data generated by automated vehicle identification sensors from Katy Freeway travelers in Houston, Texas, to estimate VOT and VOR based on revealed preferences of these travelers. Lane choice models were developed to examine the factors influencing travelers’ lane choice decisions in different traffic conditions and to estimate their VOT. Models with two independent variables— travel time and toll—resulted in an estimated VOT from $1.96 to $8.06/h for all trips on a monthly basis. The research could not conclude whether the VOR had any impact on travelers’ lane choice decisions. The percentage of managed-lane trips was higher for the those who traveled the whole length of the managed–general-purpose lanes than for those who traveled only a part of the managed–general-purpose lanes. This difference might be the result of easier accessibility at the end of the managed lanes compared with that for midpoints.
High-Speed Rail and Manufacturing Agglomeration
Authors: Sun Bowen , Yu Haitao , Peng Zhong-Ren , Gao Ya
Published: September 2017

In China, the roles played by high speed rail (HSR) in improving regional accessibility and promoting urban growth have recently generated significant research interest. However, the question as to how HSR could shape urban development seems rather complex. This paper aims to discuss HSR's role in shaping urban economic development by tracing links from HSR to manufacturing agglomeration with panel data from the Beijing–Guangzhou HSR network in China from 2000 to 2015. On the basis of the new economic geography model, market potential and manufacturing wages are incorporated into the analysis framework, and a treatment effect model is used to account for the endogeneity of HSR in the study. Model results provide three conclusions. First, in general, HSR significantly increases manufacturing agglomeration for HSR cities. Second, an inverted-U relationship between the agglomeration impact of HSR and market potential is confirmed. That is, while the agglomeration effect by HSR is significantly within a threshold level of market potential, HSR in fact has a negative effect, or the dispersion effect, on manufacturing agglomeration beyond the threshold level. Third, the agglomeration impact of HSR differs across regions. For example, the agglomeration impact of HSR is more significant in the second-tier HSR cities than in major HSR cities, indicating the overall trend of regional integration and economic convergence among different regions of HSR through time. Results from this study are useful for policy makers as well as for researchers for analyzing the economic implications of HSR in the future.
Vegetable Intercropping in a Small-Scale Aquaponic System
Authors: Maucieri Carmelo , Nicoletto Carlo , Schmautz Zala , Sambo Paolo , Komives Tamas , Borin Maurizio , Junge Ranka
Published: September 2017

This paper reports the results of the first study of an aquaponic system for Pangasianodon hypophthalmus production that uses Lactuca sativa L. (lettuce) and Cichorium intybus L. rubifolium group (red chicory) intercropping in the hydroponic section. The experiment was conducted in a greenhouse at the Zurich University of Applied Sciences, Wädenswil, Switzerland, using nine small-scale aquaponic systems (each approximately 400 L), with the nutrient film technique (NFT). The intercropping of vegetables did not influence the water temperature, pH, electric conductivity (EC), oxidation–reduction potential, nor O2 content. Intercropping with red chicory increased the lettuce sugar content (+16.0% and +25.3% for glucose and fructose, respectively) and reduced the lettuce caffeic acid content (−16.8%). In regards to bitter taste compounds (sesquiterpene lactones), intercropping reduced the concentrations of dihydro-lactucopicrin + lactucopicrin (−42.0%) in lettuce, and dihydro-lactucopicrin + lactucopicrin (−22.0%) and 8-deoxy–lactucin + dihydro-lactucopicrin oxalate (−18.7%) in red chicory, whereas dihydro-lactucin content increased (+40.6%) in red chicory in regards to monoculture. A significantly higher organic nitrogen content was found in the lettuce (3.9%) than in the red chicory biomass (3.4%), following the intercropping treatment. Anion and cation contents in vegetables were affected by species (Cl−, NO3−, PO43−, SO42−, and Ca2+), intercropping (K+ and Mg2+), and species × intercropping interactions (NO2− and NH4+). Experimental treatments (monoculture vs intercropping and distance from NFT inlet) did not exert significant effects on leaf SPAD (index of relative chlorophyll content) values, whereas the red coloration of the plants increased from the inlet to the outlet of the NFT channel. Intercropping of lettuce and red chicory affected the typical taste of these vegetables by increasing the sweetness of lettuce and changing the ratio among bitter taste compounds in red chicory. These results suggest intercropping as a possible solution for improving vegetable quality in aquaponics. Although the results are interesting, they have been obtained in a relatively short period, thus investigations for longer periods are necessary to confirm these findings. Further studies are also needed to corroborate the positive effect of the presence of red chicory in the system on fish production parameters.
Modulation of Nrf2 by Olive Oil and Wine Polyphenols and Neuroprotection
Authors: Martínez-Huélamo Miriam , Rodríguez-Morató Jose , Boronat Anna , De la Torre Rafael
Published: September 2017

Strong adherence to a Mediterranean diet is associated with improved cognitive function and a lower prevalence of mild cognitive impairment. Olive oil and red wine are rich sources of polyphenols which are responsible in part for the beneficial effects on cognitive functioning. Polyphenols induce endogenous antioxidant defense mechanisms by modulating transcription factors such as the nuclear factor (erythroid-derived 2)-like 2 (Nrf2). This review discusses the scientific data supporting the modulating effect of olive oil and red wine polyphenols on Nrf2 expression, and the potential health benefits associated with cognitive functioning.
Alpha-Lipoic Acid Downregulates IL-1β and IL-6 by DNA Hypermethylation in SK-N-BE Neuroblastoma Cells
Authors: Dinicola Simona , Proietti Sara , Cucina Alessandra , Bizzarri Mariano , Fuso Andrea
Published: September 2017

Alpha-lipoic acid (ALA) is a pleiotropic molecule with antioxidant and anti-inflammatory properties, of which the effects are exerted through the modulation of NF-kB. This nuclear factor, in fact, modulates different inflammatory cytokines, including IL-1b and IL-6, in different tissues and cell types. We recently showed that IL-1b and IL-6 DNA methylation is modulated in the brain of Alzheimer’s disease patients, and that IL-1b expression is associated to DNA methylation in the brain of patients with tuberous sclerosis complex. These results prompted us to ask whether ALA-induced repression of IL-1b and IL-6 was dependent on DNA methylation. Therefore, we profiled DNA methylation in the 5’-flanking region of the two aforementioned genes in SK-N-BE human neuroblastoma cells cultured in presence of ALA 0.5 mM. Our experimental data pointed out that the two promoters are hypermethylated in cells supplemented with ALA, both at CpG and non-CpG sites. Moreover, the observed hypermethylation is associated with decreased mRNA expression and decreased cytokine release. These results reinforce previous findings indicating that IL-1b and IL-6 undergo DNA methylation-dependent modulation in neural models and pave the road to study the epigenetic mechanisms triggered by ALA.
Residual Stress and Deformation Analysis in Butt Welding on 6 mm SUS304 Steel with Jig Constraints Using Gas Metal Arc Welding
Authors: Kung Chi-Liang , Hung Cheng-Kuang , Hsu Chao-Ming , Chen Cheng-Yi
Published: September 2017

This article proposes a novel method for analyzing residual stress and deformation in butt welding on 6 mm SUS304 stainless steel plates, using MSC.MARC, a commercial finite element method software, to find the best location for jig fixtures that will minimize welding deformation. Simulation and experimental studies show that a distance of 100 mm between the jig center and the welding bead center is best for inhibiting welding deformation when the jigs experience downward displacement at 0 mm on the steel plate; the total displacement is only about 1.1 mm in the case of a 300 × 250 × 6 mm SUS304 steel plate. In addition, a numerical model shows that four jigs with pitches of 200 mm can better reduce welding deformation than six jigs with pitches of 100 mm. The largest residual stress after welding occurs around the weld bead center, and the residual stress away from the welding bead center increases gradually when jigs have been applied on the steel plate to prevent deformation. The reaction force of the jigs on the steel plate has no further effect in reducing deformation. We conclude that commercially available jigs can inhibit deformation during the welding process.
Production of Aerated Foamed Concrete with Industrial Waste from the Gems and Jewels Sector of Rio Grande do Sul-Brazil
Authors: Pedro Rudimar , Tubino Rejane , Anversa Jonas , De Col Denisar , Lermen Richard , Silva Rodrigo
Published: September 2017

The use of solid waste for the development of new building materials has been an alternative to reduce environmental impacts through the preservation of natural resources. In this context, this paper evaluates the possibility of using agate gemstone waste, called rolled powder, which basically consists of silica (SiO2), in the manufacture of aerated foamed concrete blocks completely replacing the natural sand. Preformed foam was used as the air entrained by mechanical stirring with a mixture of natural foaming agents derived from coconut. To produce test specimens, the water/cement ratio and foam concentrations were varied, with three and four levels, respectively. The specimens were left for 28 days at room temperature to be cured, and then underwent analysis to determine their compressive strength, density, and the distribution of air-voids. The experiments demonstrated that the best water/cement ratio was 1.28 for 18% (of total solid mass) addition of foam, which generated a sample with a density of 430 kg/m3, and a compressive strength of 1.07 MPa. The result for compressive strength is 11% smaller than the requirements of the Brazilian standard (NBR 13438) for autoclaved aerated concrete blocks, but the results are promising.

Published: September 2017

The grid nudging technique is often used in regional climate dynamical downscaling to make the simulated large-scale fields consistent with the driving fields. In this study, we focused on two specific questions about grid nudging: (1) which nudged variable has a larger impact on the downscaling results; and (2) what is the “optimal” grid nudging strategy for each nudged variable to achieve better downscaling result during summer over the mainland China. To solve these queries, 41 three-month-long simulations for the summer of 2009 and 2010 were performed using the Weather Research and Forecasting model (WRF) to downscale National Centers for Environmental Prediction (NCEP) Final Operational Global Analysis (FNL) data to a 30-km horizontal resolution. The results showed that nudging horizontal wind or temperature had significant influence on the simulation of almost all conventional meteorological elements, while nudging water vapor mainly affected the precipitation, humidity, and 500 hPa temperature. As a whole, the optimal nudging time was one hour or three hours for nudging wind, three hours for nudging temperature, and one hour for nudging water vapor. The optimal nudged level was above the planetary boundary layer for almost every nudged variable. Despite these findings, it should be noted that the optimum nudging scheme varied with simulated regions and layers, and dedicated research for different regions, seasons, and model configuration is advisable.

Ambient concentrations of both fine particulate matter (PM2.5) and particulate matter with an aerodynamic diameter less than 10 micron (PM10) were measured from 10 June 2015 to 13 July 2015 at three locations surrounding the Cheswick Power Plant, which is located between the boroughs of Springdale and Cheswick, Pennsylvania. The average concentrations of PM10 observed during the periods were 20.5 ± 10.2 μg m−3 (Station 1), 16.1 ± 4.9 μg m−3 (Station 2) and 16.5 ± 7.1 μg m−3 (Station 3). The average concentrations of PM2.5 observed at the stations were 9.1 ± 5.1 μg m−3 (Station 1), 0.2 ± 0.4 μg m−3 (Station 2) and 11.6 ± 4.8 μg m−3 (Station 3). In addition, concentrations of PM2.5 measured by four Pennsylvania Department of Environmental Protection air quality monitors (all within a radius of 40 miles) were also analyzed. The observed average concentrations at these sites were 12.7 ± 6.9 μg m−3 (Beaver Falls), 11.2 ± 4.7 μg m−3 (Florence), 12.2 ± 5.3 μg m−3 (Greensburg) and 12.2 ± 5.5 μg m−3 (Washington). Elemental analysis for samples (blank – corrected) revealed the presence of metals that are present in coal (i.e., antimony, arsenic, beryllium, cadmium, chromium, cobalt, lead, manganese, mercury, nickel and selenium).
The Variability of Ozone Sensitivity to Anthropogenic Emissions with Biogenic Emissions Modeled by MEGAN and BEIS3
Authors: Kim Eunhye , Kim Byeong-Uk , Kim Hyun , Kim Soontae
Published: September 2017

In this study, we examined how modeled ozone concentrations respond to changes in anthropogenic emissions when different modeled emissions of biogenic volatile organic compounds (BVOCs) are used. With biogenic emissions estimated by the Model of Emissions of Gases and Aerosols from Nature (MEGAN) and the Biogenic Emissions Inventory System Version 3 (BEIS3), the Community Multi-scale Air Quality with the High-order Direct Decouple Method (CMAQ-HDDM) simulations were conducted to acquire sensitivity coefficients. For the case study, we chose 17–26 August 2007, when the Southern Korean peninsula experienced region-wide ozone standard exceedances. The results show that modeled local sensitivities of ozone to anthropogenic emissions in certain NOx-saturated places can differ significantly depending on the method used to estimate BVOC emission, with an opposite trend of ozone changes alongside NOx reductions often shown in model runs using MEGAN and BEIS3. Findings of increased ozone concentrations with one model and decreased ozone concentrations with the other model implies that estimating BVOCs emissions is an important element in predicting variability in ozone concentration and determining the responses of ozone concentrations to emission changes, a discovery that may lead to different policy decisions related to air quality improvement. Quantitatively, areas in the 3-km modeling domain that experienced daily maximum one-hour ozone concentrations greater than 120 ppb (MDA1O3) showed differences of over 20 ppb in MDA1O3 values between model runs with MEGAN and BEIS3. For selected monitoring sites, the maximum difference in relative daily maximum eight-hour ozone concentrations (MDA8O3) response between the methods to model BVOCs was 4.2 ppb in MDA8O3 when we adopted a method similar to the Relative Reduction Factor used by the US Environmental Protection Agency (EPA).
Assimilating Conventional and Doppler Radar Data with a Hybrid Approach to Improve Forecasting of a Convective System
Authors: Gao Shibo , Huang Danlian
Published: September 2017

A hybrid ensemble adjustment Kalman filter—three-dimensional ensemble—variational (EAKF-En3DVar) system is developed to assimilate conventional and radar data, and is applied to a convective case in Colorado and Kansas, USA. The system is based on the framework of the Weather Research and Forecasting model’s three-dimensional variational (3DVar) and Data Assimilation Research Testbed. A two-step assimilation procedure with a shorter length scale and analysis cycle is used to reduce analysis noise in radar data assimilation. Results show that the hybrid experiment assimilating only conventional data improves the quantitative precipitation forecast (QPF) and quantitative reflectivity forecast over those of a 3DVar experiment, and the improvements are also evident after assimilating radar data. The assimilation of radar data substantially improves the QPF up to seven hours, with either the 3DVar or hybrid method. The hybrid experiment assimilating both conventional and radar data forecasts a more accurate convective system in terms of structure, spatial extent and intensity and produces increased low-level cooling and mid-level warming in the convective region. These improvements are attributable to an improved forecast background field of wind, temperature and water vapor mixing ratio, with maximum root mean square error reduction at the tropopause and near the surface.

Published: September 2017

This paper focuses on an integrated multi-methodological evaluation process; it aimed at supporting public administrators in developing alternative strategies for intervention in urban planning and urban regeneration processes that focus on abandoned urban areas located in a central position. In order to transform crisis areas into areas with new opportunities, starting with their redevelopment and enhancement, the article proposes a selection of evaluation tools that can support and steer the decision maker’s choice of alternative scenarios for intervention. For this purpose, the contribution develops an integrated system of evaluation methodologies for decision-making support, which includes different components and a plurality of points of view, even of conflicting types, providing a more transparent description of the decision-making process. The methodological approach was applied to a pilot case study that concerned the choice of priority intervention between two abandoned and blighted areas located in the central area of the city of Reggio Calabria.

Published: September 2017

Bismuth complex oxides, in particular, bismuth tungstate, have recently attracted attention as promising photocatalytic materials for water treatment processes. In the present work, photocatalytic bismuth tungstate films were prepared by pulsed direct current (DC) reactive magnetron sputtering of Bi and W targets in an Ar/O2 atmosphere onto spherically-shaped glass beads. The uniform coverage of the substrate was enabled by the use of oscillating bowl placed underneath the magnetrons. The atomic ratio of Bi/W was varied through the variation of the power applied to the magnetrons. The deposited coatings were analyzed by the scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), X-ray photoelectron spectroscopy and atomic force microscopy. The photocatalytic properties of the films were studied via the methylene blue (MB) degradation process under artificial (fluorescent light) and natural (sunlight) irradiation, and compared to the photocatalytic performance of titanium dioxide coatings deposited onto identical substrates. The results showed that the photocatalytic performance of bismuth tungstate and bismuth oxide-coated beads was superior to that exhibited by TiO2-coated beads. Overall, reactive magnetron co-sputtering has been shown to be a promising technique for deposition of narrow band gap bismuth-based semiconducting oxides onto irregularly-shaped substrates for potential use in water treatment applications.
A Guide to and Review of the Use of Multiwavelength Raman Spectroscopy for Characterizing Defective Aromatic Carbon Solids: from Graphene to Amorphous Carbons
Authors: Merlen Alexandre , Buijnsters Josephus , Pardanaud Cedric
Published: September 2017

sp2 hybridized carbons constitute a broad class of solid phases composed primarily of elemental carbon and can be either synthetic or naturally occurring. Some examples are graphite, chars, soot, graphene, carbon nanotubes, pyrolytic carbon, and diamond-like carbon. They vary from highly ordered to completely disordered solids and detailed knowledge of their internal structure and composition is of utmost importance for the scientific and engineering communities working with these materials. Multiwavelength Raman spectroscopy has proven to be a very powerful and non-destructive tool for the characterization of carbons containing both aromatic domains and defects and has been widely used since the 1980s. Depending on the material studied, some specific spectroscopic parameters (e.g., band position, full width at half maximum, relative intensity ratio between two bands) are used to characterize defects. This paper is addressed first to (but not limited to) the newcomer in the field, who needs to be guided due to the vast literature on the subject, in order to understand the physics at play when dealing with Raman spectroscopy of graphene-based solids. We also give historical aspects on the development of the Raman spectroscopy technique and on its application to sp2 hybridized carbons, which are generally not presented in the literature. We review the way Raman spectroscopy is used for sp2 based carbon samples containing defects. As graphene is the building block for all these materials, we try to bridge these two worlds by also reviewing the use of Raman spectroscopy in the characterization of graphene and nanographenes (e.g., nanotubes, nanoribbons, nanocones, bombarded graphene). Counterintuitively, because of the Dirac cones in the electronic structure of graphene, Raman spectra are driven by electronic properties: Phonons and electrons being coupled by the double resonance mechanism. This justifies the use of multiwavelength Raman spectroscopy to better characterize these materials. We conclude with the possible influence of both phonon confinement and curvature of aromatic planes on the shape of Raman spectra, and discuss samples to be studied in the future with some complementary technique (e.g., high resolution transmission electron microscopy) in order to disentangle the influence of structure and defects.

Published: September 2017

The HEA-CoCrFeNiAl0.3 thin film in this study has been successfully developed by radio frequency (RF) magnetron sputtering to meet the increasing demand in engineering applications. Its microstructure and surface profile were investigated accordingly. The as-synthesized HEA film was found to have a homogeneous element distribution and ultra-smooth surface, exhibiting a typical face-centered cubic (FCC) solid solution. The film showed better mechanical properties than its bulk counterpart, with a Young’s modulus and hardness of ~201.4 GPa and ~11.5 GPa, respectively. Furthermore, corrosion tests demonstrated decreased sensitivity to localized corrosion in comparison to the commercial 304 stainless steel in NaCl solution.
In Silico Prediction of Growth and Dissolution Rates for Organic Molecular Crystals: A Multiscale Approach
Authors: Elts Ekaterina , Greiner Maximilian , Briesen Heiko
Published: September 2017

Solution crystallization and dissolution are of fundamental importance to science and industry alike and are key processes in the production of many pharmaceutical products, special chemicals, and so forth. The ability to predict crystal growth and dissolution rates from theory and simulation alone would be of a great benefit to science and industry but is greatly hindered by the molecular nature of the phenomenon. To study crystal growth or dissolution one needs a multiscale simulation approach, in which molecular-level behavior is used to parametrize methods capable of simulating up to the microscale and beyond, where the theoretical results would be industrially relevant and easily comparable to experimental results. Here, we review the recent progress made by our group in the elaboration of such multiscale approach for the prediction of growth and dissolution rates for organic crystals on the basis of molecular structure only and highlight the challenges and future directions of methodic development.
