Published: December 2020

A horticultura demanda alta produtividade, necessitando de qualidade e uniformidade inicial de suas mudas com implicação direta desde o seu desenvolvimento até o plantio definitivo. Entre as espécies hortícolas, destaca-se a couve-flor que apresenta forma e sabor característico, sendo muito consumida no país o ano inteiro. Assim, o objetivo deste trabalho foi avaliar a emergência de plântulas e a produção de mudas de couve-flor em diferentes substratos e regime de irrigação. O experimento foi conduzido na estufa, em delineamento inteiramente casualizado, organizado em esquema fatorial 7x3 (sete composições de substratos: nas proporções volumétricas de 1:0:0; 0:1:0; 0:0:1; 1:1:1; 1:1:0; 1:0:1 e 0:1:1, com os substrato comercial Carolina Soil®, casca de arroz carbonizada e areia, respectivamente) e (três regimes de irrigações: 1; 2 e 3 vezes por dia, por trinta minutos cada, em sistema Deep Film Technique), com quatro repetições, sendo cada unidade experimental composta por oito sementes/plântulas. A semeadura ocorreu em bandejas plásticas alveoladas de 204 alvéolos, com irrigação diária nos regimes hídricos supracitados. As contagens das plântulas emergidas ocorreram diariamente até aos 21 dias após a semeadura (DAS). Avaliaram-se, nesta ocasião, o índice de velocidade, o tempo médio, a velocidade média e a frequência de emergência, aos 37 DAS, foram avaliados a altura da parte aérea, o comprimento radicular, o número de folhas e a estabilidade do torrão. Verificou-se que a interação entre as composições de substratos e os regimes de irrigação promoveram boas condições para a emergência de plântulas, bem como para a formação de mudas de couve-flor. Recomendando-se as composições de substratos 1:0:0 e 1:1:0, entre duas a três irrigações de trinta minutos cada, em sistema Deep Film Technique.

“Um jeito negro de ser e viver”: (re) inventando a vida no contexto da pandemia da covid-19 – o que dizem as crianças negras e suas mães
Authors: Franco Nanci Helena Reboucas , Figueiredo Soares Maria Patricia 
Published: December 2020

O artigo tem como objetivo analisar como a vida das crianças negras de um Centro Municipal de Educação (CMEI) em Salvador - e de suas mães - tem sido (re) inventadas no contexto da pandemia da Covid-19. Para tanto, discute-se o racismo, elemento estruturante da sociedade, documentas legais que amparam as crianças e as infâncias destacando o direito à vida e a educação, fazendo um contraponto com as narrativas dos sujeitos da pesquisa. Do ponto de vista teórico-metodológico é uma abordagem qualitativa de cunho exploratório, respaldada por Rosemberg (1996), Cavalleiro (2003), Dias (2007), Abramovicz (2016), Nunes (2016), Franco; Ferreira (2017), entre outros. Os resultados encontrados apontam que o pertencimento étnico-racial e as condições materiais de existência organizam a vida dos sujeitos da pesquisa. Conclui-se que as crianças negras e suas mães têm um “jeito negro de ser e viver” (MAKOTA VALDINA, 2005), ancorado nos valores civilizatórios afro-brasileiros (TRINDADE, 2010), e que isso impacta na forma como elas (re) inventam a vida, construindo estratégias individuais e/ou coletivas para ser/estar no mundo.
Active phytochemicals present in the Guava Tree (Psidium Guajava) leaf Extracts that grow in Uganda.
Authors:   , Serunjogi David 
Published: December 2020

Background: The Guava tree is small in the myrtle family (Myrtaceae), native to Mexico, Central America, the Caribbean, and northern South America. It contains a high content of organic and inorganic compounds like secondary metabolites such as antioxidants, polyphenols, antiviral compounds, and anti-inflammatory compounds. Such chemicals are produced by plants through primary or secondary metabolism whereas Guava products have been used as a source of medicine and while they have proved to work effectively, little is known about the composition of such plant origin products from Uganda. Methodology: The maceration method of extraction was used to obtain the guava extract. The leaves were crushed into a powder using a blender and 20g of the powder was added into differently labeled beakers containing 100mls of distilled water and 100mls of increasing concentration of methanol from 30%, 50%, and 70%. The analysis involved Saponins, Phenols and Tannins, Terpenoids, Flavonoids, and Glycosides, and Laboratory tests are done included the Ferric Chloride test, Shinoda test, Salkowski test, Concentrate H2SO4 test, and Foam test. Results and discussion: Phytochemicals (Saponins, Phenols and Tannins, Terpenoids, Flavonoids, and Glycosides) are present in the leaves of the guava tree (Psidium guajava) that grows in Uganda. Psidium guajava extract obtained using distilled water contained all the phytochemicals tested apart from terpenoids which showed a negative test result. Methanol of increasing concentrations can also be used to extract phytochemicals from the leaves. Conclusions and recommendations: It’s now evident that the Guava tree that grows in Uganda contains phytochemicals (secondary metabolites). Water and methanol of 30%, 50%, and 70% can be used for extraction. Future detailed studies in Africa should focus on the purification of these active secondary metabolites and also determine their concentration. Other parts of the plant such as its bark, roots, and fruits need to be studied.

AbstractObjectivesTo describe CSF‐defined neuronal intermediate filament (NIF) autoimmunity.MethodsNIF‐IgG CSF‐positive patients (41, 0.03% of 118599 tested, 1996–2019) were included (serum was neither sensitive nor specific). Criteria‐based patient NIF‐IgG staining of brain and myenteric NIFs was detected by indirect immunofluorescence assay (IFA); NIF‐specificity was confirmed by cell‐based assays (CBAs, alpha internexin, neurofilament light [NF‐L]), heavy‐[NF‐H] chain).ResultsSixty‐one percent of 41 patients were men, median age, 61 years (range, 21–88). Syndromes were encephalopathy predominant (23), cerebellar ataxia predominant (11), or myeloradiculoneuropathies (7). MRI abnormalities (T2 hyperintensities of brain, spinal cord white matter tracts. and peripheral nerve axons) and neurophysiologic testing (EEG, EMG, evoked potentials) co‐localized with clinical neurological phenotypes (multifocal in 29%). Thirty patients (73%) had ≥ 1 immunological perturbation: cancer (paraneoplastic), 22; systemic infection (parainfectious [including ehrlichosis, 3] or HIV), 7; checkpoint‐inhibitor cancer immunotherapy, 4; other, 5. Cancers were as follows: neuroendocrine‐lineage carcinomas, 12 (small cell, 6; Merkel cell, 5; pancreatic, 1 [11/12 had NF‐L‐IgG detected, versus 8/29 others, P = 0.0005]) and other, 11. Onset was predominantly subacute (92%) and accompanied by inflammatory CSF (75%), and immunotherapy response (77%). In contrast, CSF controls (15684 total) demonstrated NIF‐IgG negativity (100% of test validation controls), and low frequencies of autoimmune diagnoses (20% of consecutively referred clinical specimens) and neuroendocrine‐lineage carcinoma diagnosis (3.1% vs. 30% of NIF cases), P < 0.0001. Median NF‐L protein concentration was higher in 8 NF‐L‐IgG‐positive patients (median, 6718 ng/L) than 16 controls.InterpretationNeurological autoimmunity, defined by CSF‐detected NIF‐IgGs, represents a continuum of treatable axonopathies, sometimes paraneoplastic or parainfectious.

AbstractOrganic near‐infrared (NIR) detectors have potential applications in biomedicine, agriculture, and manufacturing industries to identify and quantify materials contactless, in real time and at a low cost. Recently, tunable narrow‐band NIR sensors based on charge‐transfer state absorption of bulk‐heterojunctions embedded into Fabry‐Pérot micro‐cavities have been demonstrated. In this work, this type of sensor is further miniaturized by stacking two sub‐cavities on top of each other. The resulting three‐terminal device detects and distinguishes photons at two specific wavelengths. By varying the thickness of each sub‐cavity, the detection ranges of the two sub‐sensors are tuned independently between 790 and 1180, and 1020 and 1435 nm, respectively, with full‐width‐at‐half‐maxima ranging between 35 and 61 nm. Transfer matrix modeling is employed to select and optimize device architectures with a suppressed cross‐talk in the coupled resonator system formed by the sub‐cavities, and thus to allow for two distinct resonances. These stacked photodetectors pave the way for highly integrated, bi‐signal spectroscopy tunable over a broad NIR range. To demonstrate the application potential, the stacked dual sensor is used to determine the ethanol concentration in a water solution.
Design Guidelines for Thermal Comfort and Energy Consumption of Triple Glazed Fluidic Windows on Building Level
Authors: Su Lingqi , Fraaß Mathias , Wondraczek Lothar 
Published: December 2020

AbstractThere has been a growing trend for buildings with large glazing size. As a trade‐off, this comes with enhanced solar heat input and/or reduced thermal insulation. Several approaches are being followed to reduce the energy consumption in these buildings, including the prolific field of smart windows. In a previous report, a fluidic window device for thermal harvesting and air‐conditioning was introduced. Using this example, the impact of a building's window‐to‐wall ratio on the triple glazed fluidic window's energy consumption and user thermal comfort is evaluated, providing design guidelines for large‐scale implementation of such smart windows with real‐world buildings. The analysis shows that the proposed window design reduces the primary energy demand as compared to using a conventional air‐conditioning system. Building simulation results indicate that the system enables satisfying thermal comfort for buildings with different window‐to‐wall ratios. Although a higher window‐to‐wall ratio improves the heat pump efficiency, it requires more heating and cooling energy. On‐device photovoltaic modules may be used for changing this relationship. In this case, the proposed device may become self‐sufficient once the transfer efficiency is high enough. It is argued that similar considerations should be applied to other types of smart window technologies.

Published: December 2020

AbstractDirect printing of conductive material on ultrathin organic films such as molecular monolayers in a non‐invasive and high‐yielding manner can potentially offer a route to unprecedented merging of molecular electronics with printed electronics. This paper reports on an approach to fabricate arrays of molecular tunnel junctions via automated direct printing of liquid‐metal microelectrode comprising eutectic gallium‐indium onto self‐assembled monolayers of n‐alkanethiolates, as a proof‐of‐concept. The printing design enables production of 350 molecular tunneling junctions per chip of 2 cm × 2 cm template‐stripped substrate and 2800 molecular tunneling junctions per batch of 4 in. diameter Si wafer, which exhibit high yields of working junctions (>80%). Printed molecular junctions have uniform geometrical contact area of ≈4.7 × 103 µm2 and guarantees reproducibility in tunneling performance. The junctions exhibit exponential decay of current density (J, A cm−2) as a function of molecular length, obeying the simplified Simmons model, and single, narrow log‐normal distributions of current density (σlog|J| = ≈0.2–0.5). Importantly, there are no significant differences in tunneling decay coefficient and charge injection current density not only between collections of junctions per printed electrode, but also between batches. Results reported herein promise high‐throughput fabrication of molecular‐scale devices via printed molecular electronics.
Oxidative Chemical Vapor Deposition of Conducting Polymer Films on Nanostructured Surfaces for Piezoresistive Sensor Applications

Published: December 2020

AbstractIn this study, a novel, fully polymeric setup for piezoresistive sensing is prepared and tested. Monolayers of polystyrene (PS) nanospheres are assembled on flexible polyethylene naphthalate substrates. Subsequently, thin layers (≈50–100 nm) of poly(3,4‐ethylenedioxythiophene) (PEDOT) are deposited conformally around the spheres by oxidative chemical vapor deposition (oCVD). Voltage−current characteristics and direct resistance measurements are performed to test the electrical properties of the samples in their unstrained state and their piezoresistive response during bending. Substrate deposition temperature (Tsub) and film thickness (tPEDOT) are used as parameters to alter properties of the PEDOT thin films; increased Tsub and tPEDOT lead to samples exhibiting lower intrinsic resistance. The electrical conductivity of the samples is estimated to range as high as tens of S cm−1. Dopant exchange of the oCVD‐PEDOT layer (intrinsically, chlorine‐doped) is performed by putting the samples in 0.5 m sulfuric acid, which decreases their resistance by ≈1/3. Regarding the piezoresistive properties of the devices, acid treatment, higher Tsub and tPEDOT (thus, lower intrinsic resistance) yield samples with increased response. As a result, gauge factors as high as 11.4 are achieved. Due to their flexibility and low‐cost, the proposed structures can be readily employed as skin‐inspired or wearable electronic devices.

AbstractOne of the critical issues in spintronics‐based technologies is to increase the data storage density. Current strategy is based on shrinking the devices size down to tens of nanometers, or several nanometers, which is reaching its limit. A new proposal is to use multi‐level cells (MLCs) to store more than two bits in each cell. In this work, the multi‐level switching is realized in CoFeB/MgO/CoFeB based nano‐scale single perpendicular magnetic tunnel junctions (p‐MTJs) with three or four stable resistance states. A large range of writing currents for each state is obtained, accompanying with a good repeatability of set‐reset operations between different states. The developed multi‐domain model perfectly matches the experimental results, reflecting the magnetic behaviors during multi‐level switching. Furthermore, current‐driven domain wall (DW) motion is revealed in the circular p‐MTJs, where the DW position can be reversibly manipulated by applied current. To design high‐performance multi‐level p‐MTJs, the parameter diagrams are calculated, suggesting various feasible strategies to improve the multi‐level switching through materials optimization and devices geometry. In summary, the demonstration of multi‐level switching in single p‐MTJ shows the high potential of realizing the new generation of p‐MTJ‐based multi‐level spintronic devices, such as multi‐level memories and spin‐neuron devices.
Anion Selection Criteria for Water‐in‐Salt Electrolytes

Published: December 2020

AbstractWater‐in‐salt electrolytes have enabled the development of novel high‐voltage aqueous lithium‐ion batteries. This study explores the reasons why analogous sodium electrolytes have struggled to reach the same level of electrochemical stability. Solution structure and electrochemical stability are compared for 11 sodium salts, selected among the major classes of salts proposed for highly concentrated electrolytes. The water environment established for each anion is related to its position in the Hofmeister series and a surprisingly strong correlation between the chaotropicity of the anion and the resulting electrochemical stability of the electrolyte is found. The search for suitable sodium salts is complicated by the fact that higher salt concentrations are needed than for their lithium equivalents. Reaching such a high concentration of >25 mol kg−1 with one or a combination of multiple sodium salts that have the desired properties remains a major challenge. Hence, alternative approaches such as multisolvent systems should be explored. The water solubility of NaTFSI can be increased from 8 to 30 mol kg−1 in the presence of ionic liquids. Such a ternary electrolyte enables stable cycling of a 2 V class sodium‐ion battery based on the NaTi2(PO4)3/Na2Mn[Fe(CN)6] electrode couple for 300 cycles at 1C with a Coulombic efficiency of >99.5%.

Published: December 2020

AbstractAll‐inorganic perovskite solar cells (PSCs) have recently received growing attention as a promising template to solve the thermal instability of organic–inorganic PSCs. However, the thermodynamic phase instability and relatively low device efficiency pose challenges. Herein, highly efficient and stable CsPbI1.5Br1.5 compositional perovskite‐based inorganic PSCs are fabricated using an organic dye, fluorescein isothiocyanate (FITC), as a passivator. The carboxyl and thiocyanate groups of FITC not only minimize the trap states by forming interactions with the under‐coordinated Pb2+ ions but also significantly increase the grain size and improve the crystallinity of the perovskite films during annealing. Consequently, perovskite films with superior optoelectronic properties, prolonged carrier lifetime, reduced trap density, and improved stability are obtained. The resulting device yields a champion efficiency of 14.05% with negligible hysteresis, which presents the highest reported efficiency for inorganic CsPbI1.5Br1.5 solar cells reported thus far. In addition, FITC can be generally adopted as attractive passivator to improve the performance of CsPbI2Br‐ and CsPbIBr2‐based PSCs. Furthermore, with a comprehensive comparison of mixed‐halide inorganic perovskites, it is demonstrated that CsPbI1.5Br1.5 compositional perovskite is a promising candidate with the optimal halide composition for high‐performance inorganic PSCs.

AbstractAlthough extensive efforts have been made to stabilize metal sodium anodes and prevent dendrite formation, it is still difficult to achieve long‐term stability at large area capacity and high current density due to a series of complex failure modes, including uneven Na nucleation and subsequent dendrite formation. Herein, an oxygen‐containing carbonized coconut framework (O‐CCF) with a 3D tubular structure is designed to inhibit dendrite growth. The 3D tubular structure can regulate the uniform distribution of electric field, making Na+ diffuse evenly on the electrode surface. The oxygen functional groups with sodiophilicity contribute to the adsorption of Na+ and reduce the Na nucleation energy on the surface of O‐CCF. The interaction of 3D tubular structure and oxygen functional groups enable Na stripping/plating over 10 000 cycles at 50 mA cm−2, as well as cycling stably for 1000 cycles with coulombic efficiency of 99.6% at 5 mA cm−2 and high areal capacity of 10 mAh cm−2. As a proof of concept, full cells of O‐CCF//Na‐Na3V2(PO4)3 (NVP) and Na‐O‐CCF//Fe7S8 are assembled and exhibit outstanding electrochemical performance. This work presents a promising strategy for fabrication of safe Na metal anodes.
