Additive-free synthesis of Li4Ti5O12 nanowire arrays on freestanding ultrathin graphite as a hybrid anode for flexible lithium ion batteries

Interest in high-power, lightweight, and flexible lithium-ion batteries (FLIBs) to fulfill the energy requirements of future flexible electronic devices is increasing. To fabricate a thin FLIB, which consists of flexible components, we herein describe, as a model study, a hybrid electrode structure that includes no binders, conductive agents or metal current collectors. A freestanding ultrathin graphite (FSG) film was used as both the current collector and the anode, over which vertically aligned Li4Ti5O12 (LTO) nanowire (NW) arrays were grown. For comparison, two different additive-free electrodes consisting of an LTO NW array on titanium (LTO–Ti) and an LTO NW array on FSG (LTO–FSG) were prepared; they exhibited discharge capacities of 158 and 154 mA h g−1, respectively. The capacities remained approximately stable even after 500 cycles at a 20C charge/discharge rate, revealing outstanding cycling stability of the electrodes. The high-rate performance of the additive-free LTO–FSG electrode revealed excellent rate capability. Finally, the flexible LTO–FSG electrode was used to assemble an FLIB. This novel approach of preparing an additive-free and flexible hybrid electrode enabled the fabrication of a high-power, thin, and lightweight FLIB that exhibited no physical deterioration or performance loss.
Bioaccumulation of Chromium, Manganese, Nickel and Lead in the Tissues of the Moggel, Labeo umbratus (Cyprinidae), From Witbank Dam, Mpumalanga

This paper focuses on the extent of Cr, Mn, Ni and Pb bioaccumulation in the different tissues of a cyprinid fish, namely the moggel (Labeo umbratus) from Witbank Dam in the Upper Olifants River catchment, The dependence of bioaccumulation on size, gender and seasons was specifically addressed. Bioaccumulation of Cr, Mn, Ni and Pb varied between the gills, liver, muscle and skin. The gills generally had the highest metal concentrations, due to their intimate contact with the environment and their importance as an effector of ionic and osmotic regulation. The liver, in its role as a storage and detoxification organ, can also accumulate high levels of metals. Muscles and skin accumulated much less metal concentrations. These two organs must be included in biomonitoring programmes because they are consumed hy the general public. Accumulation of the metals decreased with an increase in fish length Therefore the smaller the fish the higher the body load of metals due to various bioaccumulation processes. The accumulation of Cr, Mn and Ni in the different tissues of male and female fish did not differ markedly It is suggested that the male testes and female ovaries should also be compared, in order to obtain further data on the differences of accumulation of metals between males and females The highest tissue concentrat ions of Cr, Mn, Ni and Pb with the exception of the muscle and skin tissues, were recorded in the summer of 1995. The higher metal concentrations in the summer, compared to autumn and winter, can possibly he attributed to a varied water temperature.

Halloysite Nanotube as Multifunctional Component in Epoxy Protective Coating

The current research explores the use of halloysite nanotube as a multifunctional filler in epoxy coating for carbon steel. Epoxy monomer loaded halloysite was incorporated into epoxy coating along with amine hardener immobilized mesoporous silica. The waterproofing, self-healing, anticorrosive abilities, and stability under weathering of the coating were evaluated. The halloysite nanotubes are able to impart better waterproofing property to the coating. The released epoxy monomer encapsulated inside the halloysite cavity upon reaction with amine curing agent immobilized in mesoporous silica recovers the damage and thereby facilitates self-healing in epoxy coating. Apart from offering healing ability to the coating, the halloysite nanotubes are able to protect the coatings for a longer period from severe weathering conditions.
Multi-Sincronização em menssage sequence charts

Message Sequence Charts (MSC) is a visual trace language, extensively used in academy and industry, to describe the communication behavior of system components and their environment. The MSC syntax and semantics are now a standard defined by the International Telecommunication Union (ITU). The motivation for this work has originated from an effort to model scenarios of mobile device applications for the purpose of automatic test generation, in the context of a collaboration project between Centro de Informática of the Universidade Federal de Pernambuco (CIn-UFPE) and Motorola Inc. Modeling some applications which involved multi-synchronization with the standard MSC has resulted in diagrams difficult to understand or with a behavior different from the intended one. We propose an extension to MSC in order to allow messages to be synchronous. The proposed synchronous messages denote events that are instantaneous (we abstract the real time duration for a communication to be established) and may involve multiple instances. Our extension is conservative in the sense that it allows diagrams to contain both synchronous and asynchronous messages. We developed a transformation algorithm which takes an extended MSC diagram and generates a diagram in the standard MSC. This transformation algorithm implements synchronous messages as a sequence of asynchronous messages following a particular handshake protocol. A second contribution of this work is the definition of a semantics for MSC (both the standard and our extension) using the process algebra CSP. The semantics is defined in an algebraic way: instances and messages of an MSC diagram are CSP processes running in parallel. The formalisation of MSC in CSP allows us to show the equivalence between an extended MSC diagram and its corresponding standard diagram (generated by the transformation algorithm). Moreover, modelling MSC as a CSP process allows us to reason about MSC diagrams by using the rich set of algebraic laws of CSP, as well as its tools, like FDR and CSP-prover. Finally, for validating this proposed strategy, an example has been development to illustrate the synchronous notation and the transformation from the extended notation to the standard one. Furthermore, we show the PTK Tool, and its use for in test case generation from MSC models.
Milkfat globules: Physico-chemical properties as a function of size

Fractions of native milkfat globules with selected sizes (average diameter from 1 to 7 μm) can be separated by microfiltration of raw whole milk using a new patented process. Properties of different native fat-globule populations were thus characterized. The small native fat globules (SFG) naturally present in milk (from submicronic to 3 μm) contain more medium-chain fatty acids and less stearic acid than large fat globules (LFG, >5 μm). The crystallization temperature of fat globules and the thickness of triglyceride crystalline subunits increase with fat-globule diameter. Using these selected fractions of fat globules in milk products, new functional properties are observed: cheeses with SFG contain more water and have a more melting texture; butter made from LFG is more yellow and has a more unctuous texture. New applications are still to be developed to take advantage of the properties of each globule-size class.

AIM: Emotional intelligence is the ability to perceive emotions, to access and generate emotions so as to assist thought, to understand emotions and emotional knowledge, and to reflectively regulate emotions so as to promote emotional and intellectual growth(Mayer &amp; Salovey, 1997). Achievement Motivation typically refers to the level of one's motivation to engage in achievement behavior based on such parameters as need for achievement, expectancy for success, and the incentive value of success(Jackson, Ahmed & amp; Heapy, 1976). The present study is aimed to investigate emotional Intelligence and achievement motivation among college students. METHOD: The study was done on 100 College students out of 50 males and 50 females were selected through purposive sampling technique. Emotional Intelligence quotient scale (Dr Dalip singh Dr NK Chadha, 2003) and Ray’s Achievement Motivation scale (John Ray, 1990) were used to collect data. Data were analyzed by using mean, S. D, independent sample t -test, pearson product moment correlation RESULT: Results of study showed that there is no significant difference in the level of Emotional Intelligence among college students across their gender. There is no significant difference in the Achievement motivation among college students based on their gender. There is no significant relationship between Emotional intelligence and Achievement motivation among college students.
Andromonoicia funcional em espécies do gênero Solanum L. (Solanaceae)

A andromonoicia funcional presente no genero Solanum lhe confere um carater peculiar, onde flores hermafroditas com estilete curto se comportam como masculinas e flores hermafrodita com estilete longo como formadoras de frutos. Com o objetivo de analisar a biologia reprodutiva de Solanum paniculatum L. , Solanum stramoniifolium Jacq. e Solanum torvum Sw. , foi investigado aspectos morfofuncionais de suas flores e o sistema reprodutivo. O trabalho foi realizado em areas antropizadas nas proximidades do campus da Universidade Federal Rural de Pernambuco - UFRPE (8°01'05"S e 34°56'48"W) e na borda da mata do Parque Estadual de Dois Irmaos - PEDI (8°07'30"S e 34°52'30"W). Foram realizadas analises de viabilidade polinica, razao polen/ovulo, morfometria, biologia floral e distribuicao dos morfos nas inflorescencias/individuo/especie. Alem de cruzamentos intra e inter morfos, nos tratamentos manual de autopolinizacao e polinizacao cruzada, sendo feitas lâminas para analise e observacao do crescimento do tubo polinico. As especies apresentam tanto flores que possuem o estilete ultrapassando o cone das anteras quanto flores em que o estilete fica abaixo do nivel das anteras. Alem disso, possuem diferencas morfologicas significativas apenas ao nivel do estilete, apresentando polimorfismo a nivel do estilete. Para S. paniculatum o valor medio do estilete foi de 1,2 cm (± 0,06) para flores de estilete longo e 0,4 cm (± 0,06) para flores de estilete curto. Ja para S. stramoniifolium, o valor medio do estilete foi de 0,9 cm ( ± 0,06) para flores que possuem estilete ultrapassando o cone das anteras e 0,31 cm ( ± 0,07) para flores de estilete curto. Quanto a especie S. torvum o valor medio do estilete foi de 0, 9 cm ( ± 0,17) para flores de estiletes longos e 0,3 cm (± 0,07) para flores de estilete curto. Existe um padrao definido quanto a proporcao de flores de estilete longo e/ou estilete curto numa inflorescencia ou mesmo nos individuos, onde mais de 80% das flores possuem estiletes que ultrapassam o cone das anteras. Geralmente, flores de estilete longo de S. stramoniifolium encontra-se em posicoes basais das inflorescencias e as flores de estilete curto em posicoes distais. Esse padrao nao foi obervado em S. paniculatum e S. torvum. Os morfos analisados oferecem viabilidade polinica acima de 97% e alta taxa de razao polen/ovulo.

Ja as flores de estilete curto nao formaram tubo polinico em nenhum tratamento. Diante do exposto, as especies podem ser enquadradas como andromonoicas funcionais, onde flores de estilete curto atuam como masculinas e flores de estilete longo como hermafroditas, possuindo a capacidade de reproducao.
Forecasting CO2 emissions in the Persian Gulf States.

The Persian Gulf States (Bahrain. Iran, Iraq, Kuwait, Qatar, Saudi Arabia and United Arab Emirate) have dominated the oil and gas sector since the discovery of oil in the region. They are the world largest producers of crude oil, producing about 35 and 25 percent of the world natural gas and crude oil respectively. The use of fossil fuels is directly linked to the release of CO2 into the environment. CO2 accounts for 58.8 percent of all greenhouse gases released via human activities, consequently, presenting a malign impact on the environment through climate change, global warming, biodiversity, acid rain and desertification among others. Due to its importance, the data on CO2 emission obtained from US EIA from 1980 – 2010 was regressed using least square techniques and projections were made to the year 2050. Results indicated that each country’s p-value was less than 0.05 which implies that the models can be used for predicting CO2 emissions into the future. The data shows the emission of CO2 by countries from the highest to the lowest in 2016 as: Iran (590.72 Mtonnes; 7.58 tonnes of CO2/person) > Saudi Arabia (471.82 Mtonnes; 18 tonnes of CO2/person) > UAE (218.58 Mtonnes; 41.31 tonnes of CO2/person) > Iraq (114.01 Mtonees; 3.71 tonnes of CO2/person) > Kuwait (92.58 Mtonnes; 36.31 tonnes of CO2/person) > Qatar (68.26 Mtonnes; 37 tonnes of CO2/person) > Bahrain (33.16 Mtonnes; 27.5 tonnes of CO2/person)". The sequence from the country with highest emission (Iran) to the country with lowest emission (Bahrain) will remain the same until 2050. A projection depicting a 7.7 percent yearly increase in CO2 emission in the Persian Gulf States.
Metallic nanoparticle-based strain sensors elaborated by atomic layer deposition

Platinum nanoparticle-based strain gauges are elaborated by means of atomic layer deposition on flexible polyimide substrates. Their electro-mechanical response is tested under mechanical bending in both buckling and conformational contact configurations. A maximum gauge factor of 70 is reached at a strain level of 0.5%. Although the exponential dependence of the gauge resistance on strain is attributed to the tunneling effect, it is shown that the majority of the junctions between adjacent Pt nanoparticles are in a short circuit state. Finally, we demonstrate the feasibility of an all-plastic pressure sensor integrating Pt nanoparticle-based strain gauges in a Wheatstone bridge configuration.
An Investigation of Secondary Formations of High Temperature Solid Oxide Fuel Cells

KASEMAN, BRIAN J., M.S., March 2012, Mechanical Engineering An Investigation of Secondary Formations of High Temperature Solid Oxide Fuel Cells Director of Thesis: David J. Bayless Solid Oxide Fuel Cells (SOFCs) are aimed to operate using coal syngas but the gas may have a negative impact on the component materials. The gas contains impurities such as phosphorus could react with an anode component gadolinia doped ceria (GDC). Nextcells with a Ni-GDC interlayer were operated at 0.7V in coal syngas containing 10 and 20ppm PH3 at 800 and 900°C for 42 hours. The power density reduced by 92% at 800°C when exposed to both PH3 concentrations. Degradation was determined to be caused by ohmic, activation, and concentration polarizations. X ray diffraction (XRD) and X ray photoelectron spectroscopy (XPS) show the formation of CePO4. It is determined that phosphorus species are detrimental to the Ni-GDC interlayer in accelerated testing. Additionally, the main components of coal syngas (hydrogen, nitrogen, carbon monoxide, carbon dioxide, and steam) may form secondary phases with the silver (Ag) current collector. SOFCs with anode Ag current collectors were operated in coal syngas at 850°C for 100 hours. XRD did not detect any secondary formations of Ag. Coal syngas is not believed to have an affect on the Ag current collector. The migration of Ag through the scandia stabilized zirconia (ScSZ) electrolyte by electroand thermomigration was also investigated. SOFCs were operated at 0.7V in H2 at 900°C for 200 hours to activate these migration mechanisms. Secondary Electron Microscope (SEM) showed Ag at the
Phytochemicals in Fruits and Vegetables

Fruits and vegetables are the most important sources of phytochemicals. Phytochemicals use for both human diets and natural antimicrobial agents in food preservation. Their benefits for health are mainly due to high antioxidant activity. Antimicrobials of plant origin are known as secondary metabolites that could play a role not only individually or jointly against food‐borne pathogens but also contribute to food flavor. Phytochemicals have a strong effect on control and prevention of natural spoilage processes and growth of microorganisms, including pathogens causing food safety issues. Microorganisms are always associated with harvested plants and slaughtered animals, the basic unprocessed materials of the food industry. Since foods consumed by humans undergo several pro‐ cessing treatments, it is important to understand the effect of such treatments on the phytochemical composition of foods.
THE HEXACO PERSONALITY MEASURE AS A PREDICTOR OF JOB PERFORMANCE AND JOB SATISFACTION

The study aimed to examine the relationship between personality traits according to the Six Factor Personality Inventory (HEXACO), and job performance and job satisfaction. A total of 852 people (433 women and 419 men) from 154 different professions participated in the study. The age range of the participants was between 20 and 74, and they were working at a job for a period between 1-40 years. Participants answered the HEXACO Personality Inventory long form and evaluated their job performance and job satisfaction on a scale between 1 and 5. To predict job performance and job satisfaction, the data was analyzed by multiple linear regression. The sub-dimensions of Modesty, Fairness, Social Self-Esteem, Liveliness, Perfectionism, Diligence and the factors of Extraversion, Conscientiousness predicted job performance, and sub-dimensions of Modesty, Liveliness, Social Boldness, Forgiveness, Patience, Diligence and the factors of Extraversion, Agreeableness, and Conscientiousness predicted job satisfaction. Afterwards, job performance and job satisfaction levels of the participants were grouped as low, moderate, high. Total HEXACO scores of these groups were compared by MANOVA for sub-dimensions and factors. Job performance groups differed in the factors of Honesty-Humility, Extraversion, Conscientiousness, Openness to Experience, and job satisfaction groups differed in the factors of Extraversion, Agreeableness, and Conscientiousness. As for the sub-dimensions, groups that were high in job performance and job satisfaction differed from the groups that were low in many personality traits.
Structural and Raman spectroscopic studies of the two M 0.50SbFe(PO4)3 (M = Mg, Ni) NASICON phases

Structures of the two M 0.50SbFe(PO4)3 (M = Mg, Ni) phases, abbreviated as [Mg0.50] and [Ni0.50], were determined at room temperature from X-ray diffraction (XRD) powder data using the Rietveld analysis. Both compounds belong to the NASICON structural family. XRD patterns of [Mg0.50] and [Ni0.50] phases were easily indexed with a primitive hexagonal unit cell [P $\overline 3 $ space group, Z = 6] similar to that already obtained for La0.33Zr2(PO4)3. Obtained unit cells parameters are [a = 8.3443(1) Å, c = 22.3629(1) Å], and [a = 8.3384(1), c = 22.3456(1) Å], respectively, for [Mg0.50] and [Ni0.50] phosphates. In both samples, the [Sb(Fe)(PO4)3] − NASICON framework is preserved and a partially-ordered distribution of Sb5+ and Fe3+ ions is observed. Raman spectroscopic study was used to obtain further structural information about the nature of bonding in [Mg0.50] and [Ni0.50] phases.
Ionic liquid pretreatment of lignocellulosic biomass

This thesis is concerned with the thermal treatment of lignocellulosic biomass using ionic liquids for the purpose of comminution via dissolution, for fractionating the biological composite and for obtaining aqueous solutions of carbohydrate monomers from the pulp via enzymatic hydrolysis. A major focus was the relationship between the choice of the anion and the effectiveness of the treatment. The synthesis of a range of 1-butyl-3-methylimidazolium ionic liquids with strongly hydrogen-bond basic anions was accomplished. Selected, process-relevant physicochemical properties were measured, such as the Kamlet-Taft solvent polarity, hygroscopicity and thermal stability. It was shown that 1-butyl-3-methylimidazolium acetate is not stable at 120°C, while other ionic liquids e.g. 1-butyl-3-methylimidazolium hydrogen sulfate exhibit very good long-term thermal stability. It was shown that hydrogen-bond basic 1-butyl-3-methylimidazolium ionic liquids attract more than stoichiometric quantities of water when exposed to air, suggesting that ionic liquid pretreatment under anhydrous conditions is difficult to achieve. Dissolution of air-dried wood chips in 1-butyl-3-methylimidazolium ionic liquids was attempted. It was shown that the large particle size and the moisture contained in the biomass hamper complete dissolution. The hydrogen-bond basicity of the ionic liquid, described by the Kamlet-Taft parameter ß, was correlated with the ability to expand as well as partially and anisotropically dissolve wood chips. Pretreatment of lignocellulosic biomass with 1-butyl-3methylimidazolium methyl sulfate, 1-butyl-3-methylimidazolium hydrogen sulfate and 1-butyl-3-methylimidazolium methanesulfonate was explored and high saccharification yields were reported. It was found that successful application of methyl sulfate and hydrogen sulfate ionic liquids requires addition of water and that comparatively high water contents are tolerated. Fractionation of lignocellulose into an insoluble cellulose fraction, a solubilised hemicellulose fraction and a lignin containing precipitate was achieved. The influence of water content, pretreatment
Synthesis and Coordination Chemistry of Hexadentate Picolinic Acid Based Bispidine Ligands.

The synthesis and CuII, NiII, ZnII, CoII, and GaIII coordination chemistry of the two isomeric hexadentate N5O ligands 6-[[9-hydroxy-1,5-bis(methoxycarbonyl)-7-methyl-6,8-bis(pyridin-2-yl)-3,7-diazabicyclo[3.3. 1]nonan-3-yl]methyl]picolinic acid (Hbispa1a) and 6-[[9-hydroxy-1,5-bis(methoxycarbonyl)-7-methyl-2,4-bis(pyridin-2-yl)-3,7-diazabicyclo[3.3. 1]nonan-3-yl]methyl]picolinic acid (Hbispa1b), picolinic acid-appended bispidines, are described. The two ligands are highly preorganized for octahedral coordination geometries and are particularly well suited for tetragonal symmetries, i.e., for Jahn-Teller labile ground states. This is confirmed by all data presented: solid-state structures, solution spectroscopy, electrochemistry, and CuII complex stabilities. Differences in the preorganization of the two isomers for the Jahn-Teller labile CuII centers are thoroughly analyzed on the basis of the crystal structures and an angular-overlap-model-based ligand-field analysis.
Moisture absorption properties of hardwood veneers modified by a sol-gel process

Abstract A new invisible nanolevel coating has been developed based on the sol-gel process for veneer finishes. The sol synthesis and its application as a protective agent is described. It could be demonstrated that a combination of organic light stabilizers and sol-gel deposits is feasible and that the resulting hybrid inorganic-organic thin films decrease moisture uptake of hardwood veneers.
