Futuristic Sustainable Energy Management in Smart Environments: A Review of Peak Load Shaving and Demand Response Strategies, Challenges, and Opportunities
Authors: Silva Bhagya Nathali , Khan Murad , Han Kijun
Published: July 2020

The emergence of the Internet of Things (IoT) notion pioneered the implementation of various smart environments. Smart environments intelligibly accommodate inhabitants’ requirements. With rapid resource shrinkage, energy management has recently become an essential concern for all smart environments. Energy management aims to assure ecosystem sustainability, while benefiting both consumers and utility providers. Although energy management emerged as a solution that addresses challenges that arise with increasing energy demand and resource deterioration, further evolution and expansion are hindered due to technological, economical, and social barriers. This review aggregates energy management approaches in smart environments and extensively reviews a variety of recent literature reports on peak load shaving and demand response. Significant benefits and challenges of these energy management strategies were identified through the literature survey. Finally, a critical discussion summarizing trends and opportunities is given as a thread for future research.

Authors: Lee Hyosun , Kim Dong-Uk , Son Jigwan , Kim Seong-Bo , Ka Jong-Ok
Published: July 2020

Recent advance of biotechnology enabled development of various living modified microorganisms (LMMs) uses in the field of environmental remediation, food industry, biopesticide, and so on. Consequently, such LMMs have the potential to be released into the natural environment, either intentionally or unintentionally, or exposed to the natural ecosystem during the applications. To investigate the unintended effects of LMMs on soil microorganism populations and communities, microcosm study was conducted using the recombinant microorganism, Corynebacterium glutamicum SEM002 carrying the D-psicose-3-epimerase from Agrobacterium tumefaciens as a model LMM. In addition, potential gene transfer from the LMMs into the soil environment in the microcosm was examined. As a result, small differences in LMMs were observed in populations of soil microorganism such as total bacteria, kanamycin-resistant bacteria, total fungi and total actinomycete. Also, more than 93% of the kanamycin resistance gene from the LMMs was degraded in the microcosm during the 90 days. On the basis of the experimental results, the LMMs showed no distinct impact on soil microorganism populations and communities.
Cruise Ship Safety Management in Asian Regions: Trends and Future Outlook
Authors: Jiao Yue , Dulebenets Maxim A. , Lau Yui-yip
Published: July 2020

The sinking of the Titanic has brought cruise ship safety onto the international agenda. However, different shipwrecks have been occurring in the cruise industry with relatively high frequency for more than one century due to human errors. In order to improve cruise ship safety, the International Maritime Organization and the Cruise Lines International Association introduced a set of safety enhancement policies and measurements. However, the expansion of ships and fairly weak safety regulations continue to pose risks of human life loss during cruise ship accidents, particularly in Asian regions. Asian countries have been constantly implementing various safety measures, but serious cruise ship accidents still occur from time to time, even after significant past experiences. Are the cruise ship accidents predominantly the result of human failures and organizational factors? This paper undertakes a detailed historical review of cruise ship accidents since 1972 through an intensive overview of the documents published by the Safety of Life at Sea (SOLAS) Convention and the Maritime Safety Committee. Furthermore, a set of case studies of representative cruise ship accidents are conducted as a part of this study. The outcomes of this study will help cruise shipping companies to better understand the factors influencing cruise ship accident occurrence and to construct appropriate safety policy measures, aiming to prevent cruise ship accidents in Asian regions.
Optimization of Flight Rescheduling Problem under Carbon Tax
Authors: Kammoun Mohamed Ali , Turki Sadok , Rezg Nidhal
Published: July 2020

The flight rescheduling problem is one of the major challenges of air traffic issue. Unforeseen bad weather conditions stimulate air traffic congestion and make the initial scheduling infeasible, resulting in significant economic losses for passengers and airlines. Furthermore, due to rigorous environmental legislations, flight rescheduling becomes a more complicated problem, as it has to deal with flight delays on the one hand, and carbon emissions on the other hand. In this paper, we address the flight rescheduling problem with an environmental requirement subject to the air capacity limitation due to bad weather conditions. A new strategy is proposed to minimize the disruption effects on planned flights, which adopted ground delay, longer route change, flight cancellation, as well speed adjustment to arrive at a scheduled time. Firstly, the objective of this study is to determine the economical flights plan in line with the new available air capacity. Secondly, by considering the environmental impact of the kerosene consumption, we illustrate the contribution of an economical decision to aircraft emissions. Experiment results are provided to show the efficiency of the proposed strategies and genetic algorithm as the used optimization method. Furthermore, the impacts of carbon tax and cost of arrival delay on the flights carbon emissions are studied.
Interregional Diversity of Social Capital in the Context of Sustainable Development—A Case Study of Polish Voivodeships
Authors: Pawlewicz Katarzyna , Pawlewicz Adam
Published: July 2020

The relationship between social capital and sustainable development challenges is of special importance. However, social capital is a complex phenomenon that is analyzed in different contexts and cannot be investigated with the use of a single variable. Social capital is difficult to define, which is why the selection of variables for measuring social capital can be problematic. The aim of this study was to analyze variations in social capital at the regional level. The study was conducted in Poland, and it covered all 16 Polish voivodeships (regions) where social capital was evaluated based on five measures: civic engagement in political and social life, degree of selfless behavior, sense of security and social confidence, formation of social structures, and the observance of social norms (external factors), and attitudes (internal factors) that foster desirable social interactions. The correlations between the above measures were also determined. Composite indicators of the analyzed measures were developed with the use of the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. The results were used to rank Polish voivodeships and group them into three classes based on the corresponding values of the adopted measures. Pearson’s correlation coefficient was used in the correlation analysis. The analysis involved a total of 26 indicators based on the data provided by Statistics Poland, the National Election Committee, Social Diagnosis project, and Moja Polis website. Polish voivodeships not only differ considerably in terms of the evaluated measures of social capital, but are also characterized by significant internal variation within each measure. The majority of Polish voivodeships were grouped in class II denoting average values of the evaluated measures, which could suggest that Poland is deficient in social capital. The Pomeranian voivodeship scored highest and the Łódź voivodeship scored lowest in the analyzed measures of social capital. A significant correlation was observed only between civic engagement in political and social life versus the formation of social structures and the observance of norms and attitudes that foster desirable social interactions.
The Exponential-Centred Skew-Normal Distribution
Authors: Martínez-Flórez Guillermo , Barrera-Causil Carlos , Marmolejo-Ramos Fernando
Published: July 2020

Data from some research fields tend to exhibit a positive skew. For example, in experimental psychology, reaction times (RTs) are characterised as being positively skewed. However, it is not unlikely that RTs can take a normal or, even, a negative shape. While the Ex-Gaussian distribution is suitable to model positively skewed data, it cannot cope with negatively skewed data. This manuscript proposes a distribution that can deal with both negative and positive skews: the exponential-centred skew-normal (ECSN) distribution. The mathematical properties of the proposed distribution are reported, and it is featured in two non-synthetic datasets.

Published: July 2020

The use of perovskite-type layered oxide K2La2Ti3O10 (Per) as a modifier of the Torlon® polyamide-imide (PAI) membrane has led to the formation of an specific structure of a dense nonsymmetrical film, namely, a thin perovskite-enriched layer (3–5 μm) combined with the polymer matrix (~30 μm). The PAI/Per membrane structure was studied by SEM in combination with energy dispersive microanalysis of the elemental composition which illustrated different compositions of top and bottom surfaces of the perovskite-containing membranes. Measurement of water and alcohol contact angles and calculation of surface tension revealed hydrophilization of the membrane surface enriched with perovskite. The transport properties of the nonsymmetrical PAI/Per membranes were studied in the pervaporation of ethanol‒ethyl acetate mixture. The inclusion of 2 wt.% Per in the PAI gives a membrane with a high separation factor and increased total flux.
Phages Needed against Resistant Bacteria
Authors: Moelling Karin
Published: July 2020

Phages have been known for more than 100 years. They have been applied to numerous infectious diseases and have proved to be effective in many cases. However, they have been neglected due to the era of antibiotics. With the increase of antibiotic-resistant microorganisms, we need additional therapies. Whether or not phages can fulfill this expectation needs to be verified and tested according to the state-of-the-art of international regulations. These regulations fail, however, with respect to GMP production of phages. Phages are biologicals, not chemical compounds, which cannot be produced under GMP regulations. This needs to be urgently changed to allow progress to determine how phages can enter routine clinical settings.
EFFECT OF POROUS STRUCTURE ON SOUND ABSORPTION OF CELLULAR CONCRETE
Authors: Fedyuk R.S. , Baranov A. , Mugahed Amran Y.H.
Published: July 2020

the compositions of gas and foam concrete with improved acoustic characteristics were developed. The optimal form of porosity, which contributes to the absorption of sound waves, both in the range of audible frequencies and at infrasonic and ultrasonic frequencies, is revealed. The mathematical model for designing sound-absorbing concrete was improved, taking into account both the porosity of the composite and the influence of the porous aggregate. The laws of synthesis of aerated concrete and foam concrete are established, which consist in optimizing the processes of structure formation due to the use of a polymineral cement-ash binder and blowing agent. The composition of the composite intensifies the process of hydration of the system, which leads to the synthesis of a polymineral heterodisperse matrix with an open porosity of more than 60%. Peculiarities of the influence of the “Portland cement – aluminosilicate – complex of modifiers” system on the rheology of the concrete mixture was identified, which can significantly reduce shear stress and create easily formed cellular concrete mixtures. The increased activity and granulometry of aluminosilicates predetermine an increase in the number of contacts and mechanical adhesion between particles during compaction, strengthening the frame of inter-pore septa. The mechanism of the influence of the composition of the concrete mixture on the microstructure of the composite is established. The presence of refined aluminosilicates and a complex of additives in the system along with cement contribute to the synthesis of the matrix with open porosity, thereby increasing the sound absorption coefficient.

RESPUESTA MOLECULAR DE LAS PLANTAS ANTE EL ESTRÉS POR INUNDACIÓN: LECCIONES APRENDIDAS DEL GEN SUB1A
Authors: Peña-Castro Julián M.
Published: July 2020

La inundación de los campos de cultivo es el segundo estrés más importante que causa pérdidas agrícolas. La inundación limita la concentración de oxígeno en el entorno de la planta, lo que ocasiona un estrés energético al impedir la obtención de energía de los carbohidratos por medio del ciclo de los ácidos tricarboxílicos y la fosforilación oxidativa. De esta manera, la fermentación etílica se convierte en la principal alternativa catabólica, lo que limita el desarrollo de la planta. Una inundación prolongada puede provocar la muerte cuando se agotan las reservas energéticas. Las plantas responden al estrés por inundación mediante una respuesta molecular coordinada que permite detectar la cantidad de oxígeno disponible, inducir la expresión de los genes de respuesta y conservar las reservas de almidón mediante la modulación de su uso en la fermentación. Los pasos anteriores están dirigidos por factores de transcripción llamados Ethylene Response Factors (ERFs), entre los que se encuentra el gen SUB1A de arroz (Oryza sativa L.). En este trabajo se revisan los avances más recientes en el entendimiento de este campo de la biología molecular vegetal, así como sus aplicaciones biotecnológicas actuales y potenciales.
Designing the Emergency Online Study Bubble
Authors: Erturk Emre
Published: July 2020

In 2020, although many students around the world are studying online from home as a result of the COVID-19 global pandemic, this situation is quite different from ordinary online study. For example, in the past, most students studying online would have still had access to campus or education centre resources, face-to-face advisors, or libraries. This research has been conducted at a New Zealand institution of higher learning, which has had to adapt quickly to these special circumstances. The researchers were actively teaching courses face-to-face prior to the lockdown; although there already were well-designed course sites, they have had to go from a blended course delivery to a completely online and isolated study mode. The current literature is already resourceful in discussing the range of technologies, different levels of using learning management systems, and the variety of instructional strategies used within e-learning. However, these accounts are of a mechanical nature and tend to look at individual pieces either on their own or as a progression, rather than looking at the learning technology environment holistically. This practical research paper is informed by reflection and concrete evidence collected while working with students remotely. There are three aims: (1) To qualitatively explore how far this team has successfully pushed their learning management systems and technologies to completely online learning, (2) To note and recommend for future research some the challenges involved including technical ones, security, and teaching staff workload, and (3) To demonstrate how the different teaching and learning elements and tools complement each other to form a digital study bubble that can be sustained. During the semester, the researchers shared a Student Engagement Matrix, which documents the teaching staff and the students’ participation in the Learning Management System (Moodle) and other tools that are used alongside the online courses, including live class sessions and meetings. The matrix columns are the levels of online engagement, the description or criteria for each level, and the third column for the evidence and comments. This paper summarizes and presents these findings. Finally, it concludes with recommendations for other practitioners and researchers.

In this paper, we present a novel method to expand a graph over a finite field into a larger one over one of

the original field’s subfields. This allows a number of different graph expansions for any given graph.

These expansions can be used in various applications, and we focus specifically on the case of decoding

NB-LDPC codes. Using the novel expanded graphs, it is possible to reduce decoding complexity of NB-

LDPC codes significantly with minimal performance losses.
El posicionamiento de marca en universidades colombianas: un desafío para la educación o estrategia de mercadeo
Authors: Balanta Castilla Nevis , Paz Montes Luisa Stella , Álvarez Paz Diego Mauricio
Published: July 2020

Es indudable la importancia del tema de la marca en las culturas y especialmente para la colombiana, en la cual las marcas hacen parte de las preferencias cotidianas y se convierten en artefactos colectivos que permean diferentes ámbitos incluyendo el de la educación y la cultura. De este modo las marcas se constituyen en huellas léxico-semánticas que revelan muchos elementos de la memoria social y cultural en el mercado y contexto colombiano.

La marca está directamente relacionada con lo que se quiere dar a conocer, con  la imagen que se pretende crear y el posicionamiento buscado; esto hace diferenciar a una universidad pública o privada y sus servicios, de las demás, concebidas a veces como  competidoras directas, indirectas y de todas aquellas que necesariamente no son competidoras pero igualmente son participantes en un mercado que tiene cada vez menos estudiantes que se matriculan en educación superior, todo ello plantea desafíos en  la defensa de una marca o buen nombre y en la creación de estrategias  de mercadeo educativo utilizadas por las instituciones para promocionar y promocionarse y para sobrevivir a la crisis actual de universidades privadas y a la disminución de estudiantes  y deserción incluso en las públicas.

As estratégias táticas das equipes de futsal veem evoluindo ao longo dos anos, migrando da tática de Goleiro Linha-GL para a de Linha Goleiro-LG. Diante disso, este estudo busca elucidar estas relações. Os dados foram coletados dos vídeos das partidas da Liga Nacional de Futsal na temporada 2018. Foram feitas observações diretas extensivas de 16 equipes, mediante anotação em planilha. Das 16 equipes analisadas, 15 utilizaram o GL ou o LG em algum momento da partida. Nove equipes utilizaram o GL, destas, cinco ultrapassaram os 5 minutos do tempo de posse de bola. Dez equipes utilizaram o LG, destas, seis equipes ultrapassaram os 5 minutos do tempo de posse de bola. Em contrapartida, a equipe ES utilizou o LG durante 24,68s, ou seja, mais do dobro da soma do tempo de posse de bola de todas as equipes analisadas. As estratégias táticas do GL e do LG foram utilizadas pela maioria das equipes, principalmente quando a equipe estava em desvantagem no placar da partida. Em contrapartida, apesar de não obter êxito, a equipe ES com uma proposta tática inovadora utilizou o LG do início ao fim do 1º e 2º tempo em todas as partidas analisadas, o que justifica a necessidade de incrementar um estudo visando analisar mais este sistema tático. Portanto, conclui-se que o sistema tático do LG está sendo o mais adotado pelas equipes, porém, carece de novos estudos sobre a sua efetividade, já que a equipe que utilizou esta estratégia por mais tempo, não teve resultados satisfatórios.
Chancery English Empowering Women Against Violence
Authors: Garceau Brooke
Published: July 2020

The benefits of Chancery English extend beyond linguistics and into social justice and healing for victims of sexual violence. Chancery English resulted in clearer, more concise prose which allowed the stories of victims to be recorded effectively. Scribes recorded these stories in court petitions seeking punishment for rapists and murderers. Existing research shows that the use of narrative helps victims to heal from sexual violence. The main texts for the current analysis are Chancery-style court petitions of three women all named Isabelle. The analysis demonstrates how these petitions and the women they concern (or their surviving loved ones) benefited from Chancery prose and were, therefore, able to bring about a greater degree of healing and justice in the human fight against sexual violence.

The Role of Education in Shaping Parental Language Choices in a Multilingual Society
Authors: Low Hui Min
Published: July 2020

In a multilingual society, the parents are faced with the need to make language choices when they interactwith their young children. Even though language choices in bi-or multilingual families have been vastly reported in the literature on childhood multilingualism, most of these reports reflected the situations involving immigrant or mixedmarriage families who live in a largely monolingual society. In this paper, I argued that the factors that influenced the making the language choices in parents living in a multilingual society are slightly different to those reported in the general literature. From the qualitative investigation with three Malaysian-Chinese families, it was found that the parent language choices were influenced by multiple factors, including the parents’ own educational experiences and language repertoires, their language attitudes, the language repertoires of the other family members, the family tradition, and most prominently, the educational choices made by the parents for the child. The findings from this investigation added perspectives to understand the extent of complexity involved in the making of language choices by parents in a multilingual society.
Retinometry : a Literature Review
Authors: Febrina Art  , Amin Ramzi , Ansyori AK
Published: July 2020

Sharp vision is a major concern in cataract cases. Sharp improvement in vision is the expected outcome of the management of cataract cases, namely by operative measures. Before surgery, there are several ophthalmological examinations that must be performed. Quantitative instruments have been developed to determine the visual potential of eyes that experience turbidity of refractive media. One examination that can be done is a retinometry examination that is the examination of the sharp potential of vision with a retinometer.

Retinometry is a process of measuring sharp eyes using a retinometer to determine the potential for sharp eyesight.  Retinometer is one tool that uses the principle of interference fringes to assess the patient's sharp vision through a cloudy lens. On a retinometer, a light source is split into two rays which then enter the least turbid lens area so that interference grating is formed on the retina. The lattice can have a vertical, horizontal or oblique meridian orientation
INFLUENCE OF THE “PUSH & FLICK” METHODOLOGY ON THE ACCURACY OF THE INDOOR HOCKEY PENALTY CORNER SHOOTING
Authors: Antonov Antonio , Zoteva Dafina , Roeva Olympia
Published: July 2020

The penalty corner (PC) is one of the most important game situations in hockey (both outdoors and indoors), which results in 30 – 40% of all goals. The aim of this paper is to study the influence of the quasi-experimental methodology on the dynamics in the development of indicators characterizing the accuracy of shooting when performing PC in the potentially effective goal zones. Through the application of InterCriteria Analysis (ICrA), the research team sought to establish relationships and directions of dependencies between indicators reflecting the accuracy of zone shooting. Four elite female indoor hockey players from the team of the National Sports Academy in Bulgaria, participants in the European Indoor Hockey Clubs Challenge, were involved in the examination sessions. According to the requirements of the quasi-experimental “Push & Flick” methodology, the duration of the specialized training was set to 16 weeks. Each player performed 4,800 shootings, or approximately 300 shootings each week. Tests were carried out at the beginning (the first week) and at the end (the sixteenth week) of the experiment in order to determine the accuracy of the shooting – push/flick from a penalty corner spot (9 meters, central from the goal line). We used InterCriteria Analysis and Variance Analysis to analyze the results. The results of the study provide valuable information related to the training and specialization of elite hockey players profiled in the execution of a penalty corner.
De novo transcriptome analysis of high growth rate Pyropia yezoensis (Bangiales, Rhodophyta) mutant with high utilization of nitrogen
Authors: Park Seo-jeong , Choi Jong-il
Published: July 2020

Pyropia yezoensis (Ueda) M.S.Hwang et H.G.Choi (Bangiales, Rhodophyta) has potentially high economic value. P. yezoensis has been used as food in East Asian countries for a long time, and, in addition to that its consumption is increasing worldwide owing to the growing interest in healthy seaweed food. A mutant (Py2K) with a high growth rate was developed using gamma rays to increase the production of P. yezoensis. De novo transcriptome analysis was performed to determine the mechanism underlying the high growth rate of this mutant. The transcriptomes from wild-type (PyWT) and mutant (Py2K) strains were assembled, and 167,165 genes were analyzed. A total of 15,979 genes were differentially expressed. Transcriptome analysis of nitrogen pathway revealed the increase in nitrogen availability through the upregulation of nitrate transporter gene (nrt) expression. Activation of nitrogen assimilation and re-assimilation and upregulation in alternative oxidase (aox) gene contributed to the increase in cellular nitrogen availability, thereby affecting the synthesis of phycobiliprotein. As a consequence, the efficiency of photosynthesis and the subsequent growth rate increased, which contributed to the color differences in thalli between PyWT and Py2K.

Locating Red Supergiants in the Galaxy IC10
Authors: Dimitrova Tzvetelina A. , Neugent Kathryn F. , Levesque Emily M. , Massey Philip
Published: July 2020

We use archival near-IR photometry to identify red supergiants (RSGs) in the starburst galaxy IC10. RSGs are the coolest of the evolved massive stars and have K and M spectral types and temperatures below 4100 K. Typically, they can be up to a thousand times the radius of the Sun, and are therefore highly luminous. Using archival 2MASS and UKIRT photometry we transformed J and K colors to effective temperatures and luminosities, which allowed us to identify the RSGs. After applying temperature and luminosity constraints and eliminating foreground stars using Gaia, we arrived at our finalized list of 138 RSGs. Of this list, 26 were confirmed RSGs based on Gaia parallaxes, with the remaining 112 being unconfirmed proposed IC10 RSGs.

The world’s forests have never been more threatened by invasions of exotic pests and pathogens, whose causes and impacts are reinforced by global change. However, forest entomologists and pathologists have, for too long, worked independently, used different concepts and proposed specific management methods without recognising parallels and synergies between their respective fields. Instead, we advocate increased collaboration between these two scientific communities to improve the long-term health of forests.

Our arguments are that the pathways of entry of exotic pests and pathogens are often the same and that insects and fungi often coexist in the same affected trees. Innovative methods for preventing invasions, early detection and identification of non-native species, modelling of their impact and spread and prevention of damage by increasing the resistance of ecosystems can be shared for the management of both pests and diseases.

We, therefore, make recommendations to foster this convergence, proposing in particular the development of interdisciplinary research programmes, the development of generic tools or methods for pest and pathogen management and capacity building for the education and training of students, managers, decision-makers and citizens concerned with forest health.

Co-creation of value between the consumer and services providers is an idea that has been receiving much attention. The purpose of this study was to investigate the influence of consumer motivation on attitudes and adoption intention of co-creational banking activities. By means of a quantitative        method, 339 surveys were collected. The research instrument was compiled from existing scales that were adopted for the purpose of this study. The proposed conceptual model and hypotheses were tested using Structural Equation Mod-eling (SEM), while scale reliability and validity was confirmed using SPSS 23. Further, AMOS 23 was used to test the model fit. The findings indicated that all seven proposed hypotheses are significant. Therefore indicating that consumer motives have a positive influence on a consumer’s attitudes       toward participating in co-creation activities, which in turn has an impact on rela-tive advantage, complexity and compatibility. Lastly, the results indicate that relationships exist between relative advantage, complexity and compatibility, respectively and adoption intention. This study adds to contextual knowledge of cocreational adoption within digital banking, and provides managers with significant insight into the potential success of digital customization and how banks can benefit from digital co-creation.

Traditional silicon-based photodetectors are limited by the band gap of silicon, which results in a limited working wavelength range. In this report, due to the excellent properties of Indium Antimonide, the InSb/Si heterojunction photodetectors are fabricated. Under ambient temperature of 280K, as-prepared photodetectors show a specific detectivity of 9.31011 cm Hz1/2/W, responsivity of 54 mA/W, on/off ratio of 5104 under the laser irradiation of 635 nm. In order to explore the influence of working temperature on device performance, the photoresponse at different temperatures was tested. This report proved that as the working temperature increases, the responsivity and specific detectivity of the device decrease, and the performance of the device becomes worse.

The influence of different acidic medium, including hydrochloric acid, nitric acid and perchloric acid on the absorbance of sodium by flame atomic absorption spectrometry was studied. The results showed that the effects of acidic medium and water on the determination of sodium were as follows: hydrochloric acid > perchloric acid > nitric acid > water. Acid effect changed with the increase of acid concentration, however, the absorbance value of sodium element decreased when the concentration of acid was higher than 1%~2%. This effect was more obvious for high content of sodium. The detection limits, repeatability and recovery of the samples under the three acidic medium were compared. The optimum acid conditions were determined and the sensitivity of the method was improved.

Chain extender plays a significant role in enhancing the final mechanical properties of thermoplastic polyurethane (TPUs) derived from polytetra methylene etherglycol (PTMG) and 4,4-diphenylmethane diisocyanate (MDI). In this research we focused on the effect that mixed chain extender of ethylene glycol (EG) and 1,4-butanediol (BDO) used has on the phase behavior and morphology of high hard block content TPUs. DSC, FTIR, and mechanical testing were mainly used to characterize the morphology and properties of the TPUs materials. Through this work we were able to show that mixed ratio of different chain extenders had dramatic effects on the properties of the TPUs. After mixing EG and BDO, the degree of hydrogen bonding, melting temperature, tensile strength, tear strength, and hardness of TPUs are all reduced, the glass transition temperature is increased. when the mixing ratio is 1: 1 , the elongation at break is increased to 672% . However, when the mixing ratio is n (EG): n (BDO) = 1: 2, the tensile strength is increased to 29.2 MPa, and the elongation at break is reduced to 353%.

The friction and wear experiment employed M-2000 friction and wear tester which friction pair made up of Q235//GCr15 steel, and lubricating oil which contains 3% new N-B-Mo ceramic anti-wear agent was adopted as the medium. The effect of content of new ceramic anti-wear agent on friction and wear property was investigated by using X-Ray diffraction (XRD), optical microscope (OM), et al, and the mechanism of ceramic anti-wear agent was also analyzed. The results showed that in the range of 50-300N load, the friction coefficient is basically related to the size of the load, and the greater the load, the greater the coefficient of friction, the size of the wear rate is not simply increased as the load increases. The wear rate was lowest when the load was 200N. Under this load, the new N-B-Mo ceramic anti-wear agent was generated BN phase which has self-lubricating property at worn surface, reduce the friction coefficient of Q235//GCr15 friction pair and the wear rate of Q235 steel, plays an anti-friction and anti-wear role.

Authors: Si Yi , Kevluzov D.S.
Published: July 2020

The cast Al-Mg2Si metal matrix composite was prepared by metal model casting process with rare earth element Nd as the modificator. The effects of modification duration and remelting times on microstructure and mechanical properties of the composite were investicated by optical microscope (OM) and electronic universal testing machine. The results show that, after introducing a proper amount of Nd, both primary and eutectic Mg2Si in the Al-18 wt.%Mg2Si composite were well modified. The morphology of primary Mg2Si is changed from irregular or dendritic to polyhedral shape and the morphology of the eutectic Mg2Si phase is altered from flake-like to very short fibrous or dot-like. Moreover, the effect is of long-lasting and remelting properties. After the composite is modified for 300 min and remelted by 6 times, its primary and eutectic Mg2Si structures are still in modification state of small block and slices, and the tensile properties of the composite are not significantly affected.

The Adsorption of NH3 on the FeS2 (100) Surface: A First-Principles Investigation
Authors: Liang Chong , Liu Xin Lu , Che Li , Yang Kun
Published: July 2020

Using first-principles calculations, we have investigated the adsorption of NHx (x =1, 2 or 3) on the FeS2 (100) surface. The adsorption configurations and adsorption energies were determined. Our calculations showed that the NHx prefers to adsorb on the surface Fe site via N atom. The NH molecule displays the strongest interaction with the FeS2 (100) surface among the three adsorbates, while NH3 is bound relatively weak to the surface. The analysis of the density of states (DOS) showed a strong hybridization between N 2p and Fe 3d states, especially for NH and NH2 adsorption. The NH3 adsorption at full coverage was found to be less favoured than at partial coverage because of the steric repulsion among the adsorbates, in agreement with the experiment.
