Published: May 2022

Cellulose, the primary component of the plant cell wall, has fueled the wood, textile, pulp and paper industries for centuries, and has recently been used for the production of renewable nanomaterials. The tight crystalline packing of glucan chains within cellulose fibrils is responsible for its superior mechanical properties but renders this material recalcitrant to biochemical and chemical breakdown and limits its use as a green resource. The presence of nanoscale dislocations within cellulose fibrils has been postulated for decades and is thought to be responsible for the production and size of cellulose nanocrystals (CNCs) following acid hydrolysis. However, dislocations have never been directly visualized and their prevalence and size have remained elusive. In this study, we have used super-resolution (SR) fluorescence microscopy to directly visualize and measure alternating crystalline and disordered regions within individual fluorescently labelled bacterial cellulose fibrils. The measured size of the crystalline regions ranges from 40 – 400 nm and shows striking overlap with the length distribution of bacterial CNCs produced through sulfuric acid hydrolysis, supporting the fringed micellar model for the supramolecular structure of cellulose fibrils. The disordered regions were found to be 20 – 120 nm in length and show heterogeneous accessibility, which directs fibril cleavage during the initial stages of cellulose acid hydrolysis. Two-colour SR imaging of cellulose fibrils and bound exoglucanases (Cel7A), in combination with degree of crystallinity measurements suggest that these dislocations are nanoscale in size, and do not result in amorphous cellulose pockets large enough to accommodate enhanced enzyme binding. Through characterization of disordered regions in cellulose fibrils, we have gained insight into the role of cellulose nanostructure in its breakdown by chemical and enzymatic means.
Predicting and rationalizing the Soret coefficient of binary Lennard-Jones mixtures in the liquid state

Published: May 2022

Thermodiffusion is a coupled heat and mass transport process, in which a temperature gradient initiates the separation of components in a mixture. It occurs in many natural and technical processes, but experimental measurements are indirect and expensive. Therefore, molecular simulations are valuable to quickly predict transport properties such as the Soret coefficient and provide insights into the underlying mechanisms on the molecular level. In the present work, the thermodiffusion behavior of binary Lennard-Jones mixtures in the liquid state was investigated by combining the individual strengths of non-equilibrium molecular dynamics (NEMD) and equilibrium molecular dynamics (EMD) simulations. On the one hand, boundary-driven NEMD simulations are useful to quickly predict Soret coefficients because they are easy to set up and straightforward to analyze. However, careful interpolation is required because the mean temperature in the measurement region does not exactly reach the target temperature. On the other hand, EMD simulations attain the target temperature precisely and yield a multitude of properties that clarify the microscopic origins of Soret coefficient trends. A detailed analysis of the Soret coefficient suggests a straightforward dependency on thermodynamic properties, whereas its dependence on dynamic properties such as the Onsager coefficients is by far more complex. Furthermore, a limit of applicability of a popular theoretical model, which mainly relies on thermodynamic data, was identified by virtue of an uncertainty analysis in conjunction with efficient empirical Soret coefficient predictions, which use model parameters of the simulated systems instead of simulation outputs. Finally, the present study underscores that a combination of predictive models and EMD and NEMD simulations is a powerful approach to shed light onto the thermodiffusion behavior of liquid mixtures.
3D and 2D aromaticies: Like oil and water? The case of benzocarborane derivatives and 3D/3D fusions

2D/2D fusion of aromatic halves leading to a global aromatic is found in many polycyclic aromatic hydrocarbons. 3D/3D aromaticity is also found in fused boranes that follow the Jemmis’ mno rule, but 2D/3D aromaticity is difficult or impossible to achieve.
Selective reductions of ketones in the presence of aldehydes with Chiralidon a superabsorbed alcohol dehydrogenase - a "green" metal free alternative to the Luche-reduction
Authors: Jeromin Guenter , Huber Eugen
Published: May 2022

The selective reduction of a keto group in the presence of an aldehyde group with a superabsorbed alcohol dehydrogenase in an organic solvent is described. Remarkably a high preference for the reduction of the keto group was found. For example the 4-acetylbenzaldehyde was reduced with Chiralidon-R to the chiral alcohol (R)-1-(4-formylphenyl)ethanol with 96.5% yield.

Published: May 2022

We present an all-in-one acoustofluidics device for controlled acoustic field-mediated injection of surfactant stabilized water-in-oil droplets. The microfluidic channels and interdigitated transducer (IDT) channels are produced on the same master wafer and cast within one PDMS slab, making our acoustofluidics device simple to construct while retaining the same height for all channels. The IDTs with a curved, serpentine, paired and focusing geometry are easily embedded into the PDMS slab by filling the IDT channels with low melting point metal alloy. In this article, we propose the working mechanism of our embedded IDTs, which we call acoustoinjection, and carry out a precise characterization by laser doppler vibrometry (LDV) and infrared imaging to describe the injection of droplets within microfluidic channels. Although we observe that the device has acoustic resonance in the MHz frequency domain, we show that it operates most efficiently for acoustoinjection in the kHz frequency domain. In this frequency domain, our acoustofluidics device generates a pressure wave that causes destabilization of the surfactant-supported droplet interface enabling the injection of aqueous solution into the water-phase of the droplet with minimum heat generation. We show droplet injection for different surfactant concentrations, droplet passing speeds, and injection rates with high accuracy. This integrated device has the potential to serve as an alternative to electric field mediated picoinjection technologies by acoustic field-mediated and non-harmful manipulation of droplets with bio-content.
A Review on Removal of Carbon Dioxide (CO2) using Zeolitic Imidazolate Frameworks: Adsorption and Conversion via Catalysis
Authors: Abdelhamid Hani Nasser
Published: May 2022

Carbon dioxide (CO2) is one of the culprit causes of global climatic changes. Furthermore, the efficient separation of CO2 from other gaseous mixtures using ZIFs-based materials is vital for several processes such as flue gas separation, gas sweetening, and natural gas processing. Zeolitic imidazolate frameworks (ZIFs)-based materials are emerging adsorbents and catalysts for CO2 gas removal via adsorption and conversion into valuable chemicals. ZIFs-based adsorbents with high adsorption/conversion efficiencies and tunable properties can be achieved by judicious synthesis and fabrication methods. We reviewed ZIF-based materials for CO2 removal via adsorption and catalysis (e.g., cycloaddition, carboxylation, hydrogenation, N-formylation, electrocatalysis, and photocatalysis). In addition, recent development methods such as membrane synthesis and ways to improve the gas separation performance of ZIF membranes were highlighted. The prospective point of view to promote industrial applications and commercialization of ZIF-based materials was briefly discussed. Once challenges such as low performance and reproducibility for ZIFs-based materials are solved, scalability and cost-effectiveness should not become issues.
Heteromultivalency enables enhanced detection of nucleic acid mutations

Published: May 2022

Detecting genetic mutations such as single nucleotide polymorphisms (SNPs) is necessary to prescribe effective cancer therapies, perform genetic analyses, and distinguish similar viral strains. Traditionally, SNP sensing uses short oligonucleotide probes that differentially bind the SNP and wildtype targets. However, DNA hybridization-based techniques require precisely tuning the probe’s binding affinity to manage the inherent trade-off between specificity and sensitivity. To address this limitation, we generate heteromultivalent DNA-functionalized particles and demonstrate optimized hybridization specificity for targets containing one or two mutations. By investigating the role of oligo lengths, spacer lengths, and binding orientation, we reveal that heteromultivalent hybridization enables fine-tuned specificity for a single SNP and dramatic enhancements in specificity for two non-proximal SNPs empowered by highly cooperative binding. Capitalizing on these abilities, we demonstrate straightforward discrimination between heterozygous cis and trans mutations and between different strains of the SARS-CoV-2 virus. Therefore, heteromultivalent hybridization offers significant improvements over conventional monovalent hybridization-based methods and may significantly impact the fields of diagnostics, genetics, and public health.
Photochemical Synthesis of (2E,4Z)-5-(anthracen-9-yl)-2-cyanopenta-2,4-dienamide
Authors: AL-KAYSI RABIH O. , Almuzarie Raghad , Islam Imadul , Bardeen Christopher J.
Published: May 2022

In this short note we describe the photochemical synthesis of (2E,4Z)-5-(anthracen-9-yl)-2-cyanopenta-2,4-dienamide (4) from the corresponding (2E,4E)-5-(anthracen-9-yl)-2-cyanopenta-2,4-dienamide (3) and subsequent purification by precipitation from aqueous surfactant. Compound like 4 belongs to a family of anthracene derivatives capable of forming crystals that can photo-mechanically deform with light. Synthesis of 3 was achieved with high yields and in less than one minute via secondary amine-catalyzed Knoevenagel condensation between commercially available (E)-3-(anthracen-9-yl)acrylaldehyde (1) and 2-cyanoacetamide (2). Photochemical conversion of a solution of the 3 in acetonitrile using light > 475 nm from a commercial blue LED leads to a mixture of 4 (87%) and unconverted 3 (13%) due to the presence of a photostationary state from overlapping absorption spectral regions. Pure 4 ( >99%) was later obtained by precipitating an organic sol1ution of the photoproduct from aqueous surfactant Sodium Dodecyl Sulfate (SDS). Pure 4 was collected in the form of acicular micro crystals that are photomechanically responsive to UV light. The products were analyzed using 1H NMR, 13C NMR, IR, UV-Vis, and HPLC.
Mussel-Inspired Surface Coating to Stabilize and Functionalize Supramolecular J-Aggregate Nanotubes Composed of Amphiphilic Cyanine Dyes
Authors: Zhang Yipeng , Lou He , Zhang Wei , Wang Mingfeng
Published: May 2022

We report a mussel-inspired strategy of polydopamine coating to stabilize and functionalize J-aggregate nanotubes formed by supramolecular self-assembly of an amphiphilic cyanine dye called C8S3 in aqueous media. Optimization of the coating condition by changing the incubation time in a slightly basic media of dopamine with different concentrations leads to conformal wrapping of the polydopamine layer with controllable thickness on the surface of the nanotubes. Compared to noncoated pristine C8S3 nanotubes, these polydopamine-coated nanotubes show enhanced stability against dilution, heating and photobleaching. Moreover, the polydopamine layer wrapping around the nanotubes serve as an adhesive for adsorption of a variety of metal ions and electroless deposition of the metal nanoparticles. Such stabilized and functionalized nanotube composites may offer a robust synthetic J-aggregate system to mimic the structure and function of light-harvesting complexes and reaction centers in photosynthetic systems.
Vaping Cannabinoid Acetates Leads to Ketene Formation
Authors: Strongin Robert , Munger Kaelas , Jensen Robert
Published: May 2022

Delta-8 THC acetate is a relatively new psychoactive cannabis product that is available online and in vape shops across the US since it is currently unregulated. Because it contains a similar substructure to vitamin E acetate, which has been shown to form the poison gas ketene during vaping, we investigated potential ketene formation from delta-8 THC acetate, as well as other cannabinoids acetates, CBN acetate and CBD acetate, under vaping conditions. Ketene was consistently observed in vaped condensates from all three acetates as well as from a commercial delta-8 THC acetate product purchased online.
Plasmon Manipulation by Post-Transition Metal Alloying
Authors: Fonseca Guzman Maria , King Melissa , Mason Noah , Ross Michael
Published: May 2022

The design of new plasmonic materials is essential for continued progress in light manipulation at nanometer length scales. Often, multimetallic nanoparticles exhibit superior catalytic, mechanical, or corrosion-resistant behavior compared to their unary counterparts. Despite these advantages, designing multimetallic plasmonic materials remains challenging because, except for Au, Ag, and Al, most metallic elements exhibit poor plasmonic behavior. Here, we describe a strategy for manipulating the plasmon resonances of noble metal nanoparticles by post-transition metal alloying. We show how the metallic properties of post-transition metals can be imparted onto the noble metals, enabling tunable higher energy plasmon resonances that maintain high extinction coefficients and enter into the ultraviolet. Importantly, theoretical analysis suggests that post-transition metal alloying with Bi, Ga, and In could enable analogously tunable plasmon resonances. Consequently, post-transition metal alloying provides a general strategy for realizing a new chemically diverse class of tunable plasmonic materials.

Searching for an assessment method for the 21st century. Student board game design and rubrics
Authors: Moncada Morales Rosa Natalia , Serratos Vázquez Maaría del Carmen
Published: May 2022

Within the booming context of teaching learners the so-called 21st-century skills, tutoring teachers in novel teaching methods, approaches, and evaluation strategies, coupled with the massive trending use of games and gamification tactics, merge a necessity for teachers to be able to join together a series of requirements if they want to keep up-to-date as a part of the 21st century educational curriculum.

In the quest to find activities that motivate English language students at the Language Center in the Autonomous Metropolitan University at Iztapalapa and Azcapotzalco campuses, it was decided to use a game-oriented activity. In many cases, a game-based approach has been used as a pedagogical activity that transmits knowledge; however, the possibility to create knowledge and to use games as evaluation tools has been set aside. Having analyzed learners’ perspective on the overall activity, it was decided that the assessment strategy needed deeper examination so that an implementation model could be proposed. It was considered that the rubrics used had the opportunity to be enriched. Thus, the types of rubrics and their characteristics were further investigated so that the rubrics initially used could be re-elaborated and improved. After the theoretical research, it was concluded that even though rubrics pose a positive assessment tool, they do need thorough planning and evaluation.

In diesem Beitrag werden in einem ersten Schritt die Inhalte und Ziele eines Seminars an der Universität Wien zum Aufbau von „Curriculumkompetenz“ bei angehenden DaF/DaZ-Lehrkräften erläutert. Zu Beginn, in der Mitte und am Ende des Wintersemesters 2020/21 reflektierten die SeminarteilnehmerInnen über die Entwicklung ihrer persönlichen Curriculumkompetenz im Rahmen von Online-Befragungen, die das Erhebungsinstrument für die Daten der in diesem Beitrag fokussierten Längsschnittstudie sind. Anschließend werden die Ergebnisse der drei Online-Befragungen präsentiert und diskutiert. Es zeigt sich, dass Studierende in ihrer universitären Ausbildung kaum je mit Fragen der Curriculumtheorie, Curriculumforschung sowie Curriculumentwicklung in Berührung kommen. Im Zuge der Leistungsbeurteilung mussten die Studierenden in sogenannten „Teacher Design Teams“ selbst DaF/DaZ-Curricula erstellen, was sich ihnen als eine ertragreiche Aufgabe darstellte. Als schwieriger hingegen gestaltete sich für sie die Curriculumforschung, die sie in ihren Seminararbeiten durchführen mussten.

Published: May 2022

Existe un gran número de estrategias de aprendizaje que se utilizan en los cursos de lenguas extranjeras (LEX). Frecuentemente, se le otorga prioridad al desarrollo de habilidades gramaticales, de comprensión lectora o de vocabulario, dejando a un lado el sentir de los estudiantes y su motivación para aprender. El uso de tándems virtuales se considera como una de las herramientas que favorece la motivación en el aprendizaje del inglés como LEX. Estos consisten en un grupo de sesiones virtuales entre estudiantes que desean aprender una lengua extranjera, en donde intercambian conocimientos y vocabulario de una manera natural. El presente trabajo tiene como objetivo identificar cambios en la motivación de los alumnos al utilizar los tándems virtuales de lengua. Se siguió una metodología cualitativa, a través del análisis del discurso en varios padlets y un grupo focal a 21 sujetos, en donde se les hicieron algunas preguntas relacionadas con su participación en el proyecto y sus experiencias. Los resultados se analizaron siguiendo como referencia los constructos del modelo de Gardner y Lambert (1972) y se encontró que el uso de tándems virtuales de lenguas favorece a la actitud, el interés, y, sobre todo, la motivación que tienen los estudiantes ante el aprendizaje del inglés como LEX.

Comparative Analysis on Road Users’ Cost Using HDM-4 Software and Manual Technique: A Case of Addis Ababa-Adama Expressway
Authors: Kebebew Biniyam , Quezon Emer T.
Published: May 2022

Continuous changes in vehicle technology, road condition, traffic compositions initiate the change or updating of road users’ cost models. So that it needs to practice a continuous revision or update periodically for realistic estimation of costs and benefits. This paper presented the relationship and comparison between road users’ cost along Addis Ababa-Adama newly constructed expressway using the Highway Development and Management (HDM-4) Software and manually using formulations developed in the Portuguese model. The method started with data collection. All input data were collected from primary and secondary sources. The primary data utilized an interview, and secondary data were sourced out from pertinent documents, both published and unpublished. More data were gathered that related to vehicles. The vehicles using the road are classified based on the manual from the Ethiopian Road Authority as cars, utilities, small bus, large bus, small truck, medium truck, heavy truck, and truck trailer. The collected data have been input into the HDM-4 interface; the output of the analysis was vehicle operating costs, travel time, and road users’ cost as a summation. Using manual technique and HDM-4 Software, Birr 128.62/km/vehicle and Birr 139.23/km/vehicle, respectively, were found from road users’ costs analysis. The result shows the difference of Birr 10.61. Also, the correlation coefficient of 0.75 is determined, which shows that the two results of road users’ costs are highly related. As a result, the study reveals that the application of HDM-4 Software and the manual technique formulations from the Portuguese model can be adopted interchangeably to calculate Road Users’ Cost of road sections in Ethiopia. Hence, the study results are expected to be an eye-opener for a future similar project by the concerned agencies.

Phytoplankton Diversity of a Demineralized Urban Wetland of Meghalaya State of Northeast India: The Spatio-temporal Variations and the Role of Abiotic Factors
Authors: Sharma Bhushan Kumar , Sharma Sumita
Published: May 2022

The authors analyze phytoplankton diversity of a small urban wetland of Meghalaya to assess biodiversity and limnology interest of small water bodies. This “slightly acidic-circumneutral, demineralized and soft water” subtropical wetland reveals diverse phytoplankton (64 species), indicates high desmid richness and highlights the speciose littoral constellations of up to 55-58 species per sample. Phytoplankton comprises dominant quantitative component of net plankton and registers Charophyta dominance; Chlorophyta > Bacillariophyta > Dinozoa > Chrysophyta > Cyanobacteria depict sub-dominance, and Euglenozoa and Cryptophyta show poor abundance at the littoral and semi-limnetic regions. The richness of phytoplankton and abundance of phytoplankton, Charophyta, Chlorophyta, Dinozoa, Chrysophyta and Cyanobacteria follow bimodal spatio-temporal variations. Closterium, Cosmarium, Staurastrum, Micrasterias, Netrium, Staurodesmus and Scenedesmus are notable genera, and 14 species collectively influence phytoplankton abundance. Phytoplankton registers high species diversity, lower dominance and high evenness. Amongst 15 abiotic factors, only the rainfall and sulphate exert notable influence individually, while the canonical correspondence analysis registers lower cumulative influence of the selected 10 factors on the littoral and semi-limnetic phytoplankton assemblages. This study merits interest for neglected biodiversity and ecology of small aquatic biotopes of India and urban wetlands in particular.
Frühkindliche Nahrungsverweigerung
Authors: Wilken Markus
Published: May 2022

Warum verweigert ein Säugling oder Kleinkind die Nahrung? Warum kommt es zur künstlichen Ernährung und wann bleibt diese bestehen? Was geht in einem Kind vor, wenn es sich von der Flasche oder dem Löffel abwendet? Hinter diesen Symptomen verbirgt sich eine komplexe Entwicklungsdynamik, die von einer nährenden Beziehung zur Nahrungsaversion führt. Aus dieser können lang anhaltende Fütterstörung und Sondendependenz entstehen. Das Verständnis der Entwicklung zur Nahrungsaversion in ihrer Komplexität ermöglicht es, gemeinsam mit dem Kind einen neuen Entwicklungspfad einzuschlagen.

Authors: Bazhenova Elena Igorevna , Kouzmina Ksenia Alexeevna , Tkacheva Irina Alexandrovna
Published: May 2022

The aim of the study is to prove that a secondary linguistic personality of students is dynamic, the level of its formation can be assessed and strengthened under certain pedagogical conditions in professionally oriented teaching a foreign (English) language to students of non-linguistic (socio-economic) specialties. In the article, the authors have analysed the phenomenon of a linguistic personality through understanding the process of a secondary linguistic personality formation. To achieve this aim, principles, conditions, criteria have been identified and the levels of a secondary linguistic personality formation have been described; a pedagogical experiment has been carried out. The scientific novelty lies in the development and description of a linguo-didactic model for the formation of a secondary linguistic personality of students in professionally oriented teaching a foreign (English) language to students of non-linguistic (socio-economic) specialties. As a result of the experimental study, the model of a secondary linguistic personality formation in professionally oriented teaching a foreign language to students of non-linguistic specialties has been validated.

The aim of the study is to substantiate the need to update educational materials on English teaching for international relations students using the example of the Institute of International Relations of the Kazan Federal University (IIR KFU) in 2022. The paper considers the particularities of English teaching based on an author’s textbook at the IIR KFU; sheds light on the specifics of working with international relations students in the new reality of 2022. The researchers describe in detail how the requirements of the Federal State Education Standard for the English Language are implemented and what additions are to be made to the teaching materials, using the example of the English textbook published by the IIR KFU educators. Scientific novelty of the work lies in determining new requirements for the content of the educational materials for the Bachelor’s degree programme in International Relations at the KFU in connection with changes in Russia’s international activities in 2022. Drawing on the experience of English teaching on the basis of texts related to the work of the European Union, the academic staff of the IIR KFU Department of Foreign Languages in the Field of International Relations are elaborating plans to structure English language teaching involving the materials on the work of international cooperation organisations as exemplified by BRICS, SCO, EAEU, in which Russia is a full member. As a result, a package of recommendations has been developed to update the practical base of texts for working with international relations students and publishing a new textbook.

Formalised elicitation of expert judgements has been used to help tackle several problematic societal issues, including volcanic crises and pandemic threats. We present an expert elicitation exercise for Piton de la Fournaise volcano, La Réunion island, held remotely in April 2021. This involved 28 experts from nine countries who considered a hypothetical effusive eruption crisis involving a new vent opening in a high-risk area. The tele-elicitation presented several challenges, but is a promising and workable option for application to future volcanic crises. Our exercise considered an “uncommon” eruptive scenario with a vent outside the present caldera and within inhabited areas, and provided uncertainty ranges for several hazard-related questions for such a scenario (e.g. probability of eruption within a defined timeframe; elapsed time until lava flow reaches a critical location, and other hazard management issues). Our exercise indicated that such a scenario would probably present very different characteristics compared to recent eruptions, and that it is fundamental to include well-prepared expert elicitations in updated civil protection evacuation plans to improve disaster response procedures.
Geology of a Neogene caldera cluster in the Borgarfjörður eystri–Loðmundarfjörður area, Eastern Iceland

Published: May 2022

The Borgarfjörður eystri–Loðmundarfjörður area in Eastern Iceland hosts several volcanic centres in a relatively small area. Large volumes of silicic, as well as an unusual amount of intermediate rocks, occur in this area, alongside other volcanic and sub-volcanic features that formed in the Miocene between 14 and 12:2 Ma. We compiled the first comprehensive geological map of the area and summarise the geology based on more than 40 years of fieldwork. We identify regionally extensive marker horizons that comprise intermediate (icelandite) and mafic (olivine basalt and porphyritic basalt) lavas. These marker horizons, along with new paleomagnetic data and some previous radiogenic dating, allow us to bracket a phase of magmatic activity that is one of the oldest in Eastern Iceland. We describe the prominent features of the volcanic centres, including remnants of collapse calderas in Njarðvík, Dyrfjöll, Breðuvík and other ignimbrite-producing vent structures in Kækjuskörð and Herfell. Notably, the area also contains extremely well exposed examples of volcanic vents, cone sheets, and unique caldera-lake sediments. We conclude with open questions to inspire future research on this understudied area.
Territorial Infrastructure: Drafting of a Calculation Evaluation Method
Authors: Negas Elsa , Seco Rui
Published: May 2022

This study proposes a method for calculating the level of urban infrastructure and basic urban services on a given territory. It aims to contribute to a more accurate knowledge of the territory and the city, through the creation of an assessment tool for the urban condition, with the goal of overcoming imprecision hindering urban planning and management. Urban infrastructure is here understood in a broad sense, integrating usual urban attributes —roads, pavements, electricity, water supply, sanitation, etc.—but also a set of urban services and equipment traditionally provided by city and urban environment—administration, representation, culture, health, education and security, among others—and also other conditions diagnosed as significant for the current evolutionary trend of extended urbanity, such as mobility—integrating roadways, public transport networks, soft mobility devices and infrastructures —and access to and integration in communication and information networks —voice and data communication, fix and mobile. The development of this calculation method takes into account different relative weights for this set of conditions in order to obtain a balanced assessment of the level of infrastructure. In the future, the next stage will consist of testing in the field in order to fine tune and validate its usability in different scenarios.

Ah, Iungui!
Authors: da Mata Renato José
Published: May 2022

Iungui é um menino que toca o coração de quem o conhece. De tanto ser ignorado, aprendeu a ficar invisível, escondeu suas asas, e fez morada segura na Arte. Por onde ele andou e viveu, precisou usar seus poderes quase mágicos para não sofrer demais. Ele era seu melhor companheiro. Por ser inteligente e criativo, reinventou-se, escondeu-se, manifestou-se em cores e desenhos, em arte de toda forma. Encantou e fez maravilhas até virar livro.
