Mapeamento das teses brasileiras relacionadas à formação continuada de professores que ensinam matemática: período 2007-2018
Authors: Silva Anderson Adelmo , Bianchini Barbara Lutaif 
Published: October 2020

Neste artigo temos por objetivo apresentar o mapeamento das teses brasileiras produzidas no período de 2007 a 2018 que abordaram, direta ou indiretamente, a formação continuada de professores que ensinam matemática. Analisamos vinte e oito teses produzidas em diferentes programas de pós-graduação por meio de seus títulos, palavras-chave, resumos e dados catalográficos. Apresentamos resultados referentes à área de concentração dos programas de pós-graduação, tipo de Universidade, ano de publicação, região do país, modelo de formação (presencial, semipresencial ou EaD), sujeitos, identificação de categorias do conhecimento docente e relação com a identidade docente. A análise revelou que vinte e duas teses foram realizadas em programas de Universidades Paulistas distribuídas em particulares e públicas (estadual e federal). Com foco na relação entre academia e escola básica, concluímos que há um interesse pontual da academia e não um espaço consolidado de produção de conhecimento para ambos os setores. Evidenciamos, ainda, que a formação continuada é utilizada como estratégia para o desenvolvimento do Conhecimento pedagógico e o Conhecimento pedagógico do conteúdo, em sua grande maioria (22 casos), ocorreu de forma presencial. Em relação aos sujeitos, observamos um equilíbrio entre o número de formações para os professores especialistas e generalistas, treze para cada e apenas uma trabalhou com os dois tipos de professores, ou seja, é uma tendência oferecer as formações separadamente. Uma lacuna é de que as teses estudadas não abordaram o Conhecimento do conteúdo, o Conhecimento dos alunos e o Conhecimento dos fins educacionais, assim como seus fundamentos filosóficos e históricos.

Abstract. Recent studies have shown the importance of new particle formation (NPF) to global cloud condensation nuclei (CCN) production, as well as to air
pollution in megacities. In addition to the necessary presence of low-volatility vapors that can form new aerosol particles, both numerical and
observational studies have shown that the dynamics of the planetary boundary layer (BL) plays an important role in NPF. Evidence from field
observations suggests that roll vortices might be favorable for inducing NPF in a convective BL. However, direct observations and estimates of the
potential importance of this phenomenon to the production of new aerosol particles are lacking. Here we show that rolls frequently induce NPF bursts
along the horizontal circulations and that the small clusters and particles originating from these localized bursts grow in size similar to
particles typically ascribed to atmospheric NPF that occur almost homogeneously at a regional scale. We outline a method to identify roll-induced
NPF from measurements and, based on the collected data, estimate the impact of roll vortices on the overall aerosol particle production due to NPF
at a boreal forest site (83 % ± 34 % and 26 % ± 8 % overall enhancement in particle formation for 3 and 10 nm
particles, respectively). We conclude that the formation of roll vortices should be taken into account when estimating particle number budgets in
the atmospheric BL.
Identification of lower-order inositol phosphates (IP5 and IP4) in soil extracts as determined by hypobromite oxidation and solution 31P NMR spectroscopy

Published: October 2020

Abstract. Inositol phosphates (IPs) are a major pool of identifiable
organic phosphorus (P) in soil. However, insight into their distribution and
cycling in soil remains limited, particularly of lower-order IP (IP5
and IP4). This is because the quantification of lower-order IP
typically requires a series of chemical extractions, including hypobromite
oxidation to isolate IP, followed by chromatographic separation. Here, for
the first time, we identify the chemical nature of organic P in four soil
extracts following hypobromite oxidation using solution 31P NMR
spectroscopy and transverse relaxation (T2) experiments. Soil samples
analysed include A horizons from a Ferralsol (Colombia), a Cambisol and a
Gleysol from Switzerland, and a Cambisol from Germany. Solution 31P nuclear magnetic resonance (NMR)
spectra of the phosphomonoester region in soil extracts following
hypobromite oxidation revealed an increase in the number of sharp signals
(up to 70) and an on average 2-fold decrease in the concentration of the
broad signal compared to the untreated soil extracts. We identified the
presence of four stereoisomers of IP6, four stereoisomers of IP5,
and scyllo-IP4. We also identified for the first time two isomers of
myo-IP5 in soil extracts: myo-(1,2,4,5,6)-IP5 and
myo-(1,3,4,5,6)-IP5. Concentrations of total IP ranged from 1.4 to
159.3 mg P per kg soil across all soils, of which between 9 % and 50 %
were comprised of lower-order IP. Furthermore, we found that the T2
times, which are considered to be inversely related to the tumbling of a
molecule in solution and hence its molecular size, were significantly
shorter for the underlying broad signal compared to for the sharp signals
(IP6) in soil extracts following hypobromite oxidation. In summary, we
demonstrate the presence of a plethora of organic P compounds in soil
extracts, largely attributed to IPs of various orders, and provide new insight
into the chemical stability of complex forms of organic P associated with soil
organic matter.

Authors: Almeida Santos Lizandra , Oliveira Reis Daniel , Fabricante Juliano Ricardo 
Published: October 2020

O presente trabalho teve como objetivo avaliar e comparar a composição, riqueza e diversidade epifítica entre forofíticos específicos no Parque Nacional Serra de Itabaiana, SE. Através de dois distintos grupos forófitos (Mangifera indica L. e espécies arbóreas nativas), todas os indivíduos das espécies epifíticas foram contabilizadas e com esses dados foram realizadas as análises estatísticas. No total foram amostrados 491 indivíduos sendo 163 nas mangueiras e 328 nas nativas, A diversidade medida pelo índice de Shannon-Wiener (H’) para o forófitos da espécie Mangifera indica foi de H’ = 1,7 e nas nativas foi de H’ = 2, 27, o valor de equabilidade também foi maior nas nativas (J’ = 0,83) quando comparado com as mangueiras (J’ = 0,71). O teste de permutação ANOSIM demostrou diferenças significativas na composição de espécies epifíticas entre os dois grupos forofíticos, tanto por Jaccard (p ? 0,01), como por Bray-Curtis (p ? 0,01). Tais resultados sugerem que a presença de forófitos não nativos afeta a composição, riqueza e a diversidade de espécies epifíticas.

AbstractNanostructured silver stands out among other plasmonic materials because its optical losses are the lowest of all metals. However, nanostructured silver rapidly degrades under ambient conditions, preventing its direct use in most plasmonic applications. Here, a facile and robust method for the preparation of highly stable nanostructured silver morphologies is introduced. 3D nanostructured gyroid networks are fabricated through electrodeposition into voided, self‐assembled triblock terpolymer scaffolds. Exposure to an argon plasma degraded the polymer and stabilized the silver nanostructure for many weeks, even in high humidity and under high‐dose UV irradiation. This stabilization protocol enables the robust manufacture of low‐loss silver nanostructures for a wide range of plasmonic applications.
Two‐Dimensional Electromechanically Transformable Metasurface with Beam Scanning Capability Using Four Independently Controllable Shape Memory Alloy Axes
Authors: Shah Syed Imran Hussain , Sarkar Anirban , Phon Ratanak , Lim Sungjoon 
Published: October 2020

AbstractThe advancements in wireless technology, especially in radar detection, where accurate target information is critically needed, have set new standards for antenna subsystems that demand higher gain and full scanning coverage in both the azimuth and elevation planes while maintaining lower cost and design simplicity. The conventional phased array usually requires complex feeding circuitry with large spatial occupancy that renders the system bulky and expensive; therefore, a reconfigurable metasurface may be a suitable alternative. Earlier research outcomes have shown different kinds of reconfigurability in designing metasurfaces for beam steering. Designing electrically reconfigurable metasurfaces using PIN diodes, varactor diodes, etc., is a well‐known approach; however, these methods suffer from poor isolation of switches, limited power handling due to nonlinearities, high cost, and complicated biasing networks. This work proposes a novel electromechanically transformable metasurface working as a beam‐steering surface with a wider tuning range in the azimuth plane and a simplified independent switching mechanism. The incorporation of four shape memory alloy (SMA) actuator springs allows swift movements in eight different directions. The electrical control of the pitches of the four springs oriented along the four different SMA axes enables adequate mechanical transformation of the 2D metasurface to obtain beam coverage capability.

Multi‐Dimensional Organic Mass Cytometry: Simultaneous Analysis of Proteins and Metabolites on Single Cells
Authors: Xu Shuting , Liu Mingxia , Bai Yu , Liu Huwei 
Published: October 2020

AbstractMass cytometry is attracting significant attention for enabling spatiotemporal high‐throughput single‐cell analysis. As the first demonstration of the simultaneous detection of single‐cell proteins and untargeted metabolites, a multi‐dimensional organic mass‐cytometry system was established by a simple microfluidic chip connected to a nanoelectrospray mass spectrometer, providing useful heterogeneous information about the cells. A series of mass probes with online‐dissociated mass tags were developed, ensuring the semi‐quantification of cell‐surface proteins and the compatibility of endogenous metabolite detection at the single‐cell level. Six cell surface antigens and ≈100 metabolites from three ovarian‐cancer cell types and two breast‐cancer cell types were successfully monitored and contributed to highly sensitive and specific cell typing. Doxorubicin‐resistant cancer‐cell analysis confirmed the applications in distinguishing rare cell phenotypes. The proposed system is simple, extensible, and promising for cell typing, drug‐resistance analysis of tumor cells, and clinical diagnosis and therapy at the single‐cell level.

Published: October 2020

AbstractLead‐free halide perovskites have drawn wide attention as alternatives to their toxic and poorly stable lead‐based counterparts. Among them, double perovskites with Cs2AgInCl6 composition, often doped with various elements, have been in the spotlight owing to their intriguing optical properties, namely, self‐trapped exciton (STEs) emission and dopant‐induced photoluminescence. This interest has sparked different synthesis approaches towards both crystals and nanocrystals, and the exploration of many alloy compositions with mono‐ and trivalent cations other than Ag+ and In3+. In this Minireview we describe the recent developments on Cs2AgInCl6 bulk crystals and nanocrystals, their synthesis strategies, intrinsic optical properties, and tunable photoluminescence originating from different alloying and doping effects. We also discuss progress on computational studies aimed at understanding the thermodynamic stability, the role of defects, and the origin of photoluminescence in relation to the STEs and the direct band gap character.
Enantioselective, Visible Light Mediated Aza Paternò–Büchi Reactions of Quinoxalinones
Authors: Li Xinyao , Großkopf Johannes , Jandl Christian , Bach Thorsten 
Published: October 2020

Abstract3‐Substituted quinoxalin‐2(1H)‐ones and various aryl‐substituted or tethered olefins underwent an enantioselective, inter‐ or intramolecular aza Paternò–Büchi reaction upon irradiation at λ=420 nm in the presence of a chiral sensitizer (10 mol %). For the intermolecular reaction with 1‐arylethenes as olefin components, the scope of the reaction was studied (14 examples, 50–99 % yield, 86–98 % ee). The absolute and relative configuration of the products were elucidated by single‐crystal X‐ray crystallography. The reaction is suggested to occur by triplet energy transfer in a hydrogen‐bonded 1:1 complex between the imine substrate and the catalyst. The intramolecular cycloaddition, consecutive reactions of the product azetidines, and an alternative reaction mode of quinoxalinones were investigated in preliminary experiments.
Synthesis of β‐myrcene‐based macroporous nanocomposite foams: Altering the morphological and mechanical properties by using organo‐modified nanoclay
Authors: Kekevi Burcu , Mert Emine Hilal 
Published: October 2020

AbstractOrgano‐modified nanoclay incorporated high internal phase emulsions (HIPEs) were successfully used for the preparation of macroporous nanocomposite foams. Due to the aim of obtaining mechanically improved foams, HIPEs were prepared by using a monomer mixture composed of β‐myrcene and ethylene glycol dimethacrylate. Accordingly, two groups of macroporous nanocomposite foams were synthesized depending on the nanoclay type. The morphological analysis demonstrated that the pore openness of the resulting nanocomposites were significantly improved due to the decrease in the average cavity size and increase in the interconnected pore size. In terms of mechanical properties, it was found that filling 1 wt% of nanoclay which is surface modified by hydrogenated tallow lead to a 33% of increment in the compression modulus, as compared to the neat foam. However, loading 5 wt% of nanoclay having octadecylamine and aminopropyltriethoxysilane surface groups caused only 11% of increment in the compression modulus, as compared to the neat foam.
