Published: November 2024

Leaf blight affecting medicinal plants like Piper longum, Tylophora indica, and Hibiscus subdariffa is a major issue in West Bengal, causing significant damage year-round. Effective management of this disease is crucial. Several chemical fungicides and Trichoderma isolates were evaluated against the disease of these plants under field condition. Carbendazim and mancozeb were found to be effective in Piper longum in terms of higher disease control (47.50 & 41.47%) with lower per cent disease incidence (49.87 & 51.47%) and per cent disease index (25.34 & 28.25%) over the control. Although all the Trichoderma isolates were not effective as chemical fungicides but Trichoderma isolate-3 was found to have more efficiency in disease control (35.23%) compared to other two isolates. Mancozeb was treated as the most effective fungicide in T. indica to control the disease (45.07%) with lower disease incidence (54.87%) and disease severity (27.34%) compared to other treatment and control plot. In contrary in H. subdariffa carbendazim was found the most effective fungicide with lowest disease incidence (47.89%) and disease severity (23.37%) resulting higher disease control (47.81%) compared to control. It was followed by cupper oxychloride and mancozeb comparatively with higher disease incidence (49.79 & 51.43%) and disease severity (25.89 & 31.78%). Whether all the Trichoderma isolates did not show significant efficacy as fungicides but Trichoderma isolate-3 showed comparatively good result in disease control (34.32%) over other two isolates and control plot. So, the aforementioned respective fungicides could be used in the control of leaf blight disease of respective medicinal plant. But to control the disease with bio agents more efficient Trichoderma culture need to be investigated.

Authors: Menezes Márcia Barbosa de 
Published: November 2024

Resumo: Este artigo tem por objetivo apresentar os caminhos, os desafios e as transformações alcançadas por uma docente do campo matemático que resolve fazer uma incursão em outra área do conhecimento completamente diferente da sua formação inicial – cartesiana, ao ingressar no mundo das Ciências Humanas através do espaço acadêmico do Núcleo de Estudos Interdisciplinares Sobre a Mulher – NEIM/UFBA. Neste percurso, a docente percebe as nuances patriarcais que envolvem a vida das mulheres, aprisionando-as às teias das construções socioculturais. Assim, a docente se reinventa e passa a se engajar numa luta social/acadêmica, buscando contribuir em processos formativos sócio culturais e políticos que visam desestabilizar os estereótipos de gênero, de raça, de classe social e outros marcadores que atingem particularmente as mulheres nos espaços das Ciências Exatas e Tecnológicas.

Published: November 2024

Resumo: Este artigo apresenta o discurso proferido por Carla Akotirene na celebração dos 40 anos do Núcleo de Estudos Interdisciplinares sobre a Mulher (NEIM/UFBA) em maio de 2023 e realiza reflexões em diálogo com as epistemologias feministas sobre as pautas levantadas, tendo como fio condutor a crítica ao feminismo acadêmico. O esforço de afirmação enquanto intelectual negra é problematizado ao longo das análises a partir de Gonzalez (1984), Collins (1990), hooks (1995) e Kilomba (2019). A tensão na busca por validação da intelectualidade, devido aos sistemas múltiplos de subordinação (Crenshaw, 2002) aprofundam a discussão e demonstram prejuízos materiais, teóricos e políticos. Esta é uma oportunidade de ampliar o debate sobre gênero e raça, mais que isso, valorizar os avanços alcançados, sinalizar as emergências no campo e efetivar uma ética antirracista para a transformação entre teoria e práxis no feminismo acadêmico do Brasil.
Palavras-chave: feminismo acadêmico; estudos feministas; intelectualidade negra; antirracismo; NEIM/UFBA.

AbstractObjectiveWe investigated the contribution to sporadic focal epilepsies (FE) of ultrarare variants in genes coding for the components of complexes regulating mechanistic Target Of Rapamycin (mTOR)complex 1 (mTORC1).MethodsWe collected genetic data of 121 Italian isolated FE cases and 512 controls by Whole Exome Sequencing (WES) and single‐molecule Molecular Inversion Probes (smMIPs) targeting 10 genes of the GATOR1, GATOR2, and TSC complexes. We collapsed “qualifying” variants (ultrarare and predicted to be deleterious or loss of function) across the examined genes and sought to identify their enrichment in cases compared to controls.ResultsWe found eight qualifying variants in cases and nine in controls, demonstrating enrichment in FE patients (P = 0.006; exact unconditional test, one‐tailed). Pathogenic variants were identified in DEPDC5 and TSC2, both major genes for Mendelian FE syndromes.InterpretationOur findings support the contribution of ultrarare variants in genes in the mTOR pathway complexes GATOR and TSC to the risk of sporadic FE and a shared genetic basis between rare and common epilepsies. The identification of a monogenic etiology in isolated cases, most typically encountered in clinical practice, may offer to a broader community of patients the perspective of precision therapies directed by the underlying genetic cause.

Authors: Foot‐Seymour Vanessa , Foot June , Wiseheart Melody 
Published: February 2019

SummaryDespite the prevalence of the spacing effect in the psychological literature, the impact of lesson timing has not yet been fully explored in real classrooms. The current study examined whether spacing could improve long‐term retention of both factual and critical thinking curriculum‐based teaching materials for children. Students 9 to 12 years old were taught to judge the credibility of websites in either three consecutive days of lessons or one lesson per week. Thirty‐five days after the final lesson, students were tested on factual knowledge and applied their knowledge to evaluating a new website. Students in the spaced condition remembered more facts from the lessons and were better able to explain their website ratings than students in the massed group.

AbstractHighly efficient conductors are strongly desired because they can lead to higher working performance and less energy consumption in their wide range applications. However, the improvements on the electrical conductivities of conventional conductors are limited, such as purification and growing single crystal of metals. Here, by embedding graphene in metals (Cu, Al, and Ag), the trade‐off between carrier mobility and carrier density is surmount in graphene, and realize high electron mobility and high electron density simultaneously through elaborate interface design and morphology control. As a result, a maximum electrical conductivity three orders of magnitude higher than the highest on record (more than 3,000 times higher than that of Cu) is obtained in such embedded graphene. As a result, using the graphene as reinforcement, an electrical conductivity as high as ≈117% of the International Annealed Copper Standard and significantly higher than that of Ag is achieved in bulk graphene/Cu composites with an extremely low graphene volume fraction of only 0.008%. The results are of significance when enhancing efficiency and saving energy in electrical and electronic applications of metals, and also of interest for fundamental researches on electron behaviors in graphene.

AbstractThe manganese dissolution leading to sharp capacity decline as well as the sluggish reaction kinetic are still major issues for manganese‐based materials as aqueous zinc‐ion batteries (ZIBs) cathodes. Here, a potassium‐ion‐stabilized and oxygen‐defect K0.8Mn8O16 is reported as a high‐energy‐density and durable cathode for neutral aqueous ZIBs. A new insight into suppressing manganese dissolution via incorporation of K+ ions to intrinsically stabilize the Mn‐based cathodes is provided. A comprehensive study suggests that oxygen defects improve electrical conductivity and open the MnO6 polyhedron walls for ion diffusion, which plays a critical role in the fast reaction kinetics and capacity improvement of K0.8Mn8O16. In addition, direct evidence for the mechanistic details of simultaneous insertion and conversion reaction based on H+‐storage mechanism is demonstrated. As expected, a significant energy output of 398 W h kg−1 (based on the mass of cathode) and an impressive durability over 1000 cycles with no obvious capacity fading are obtained. Such a high‐energy Zn‐K0.8Mn8O16 battery, as well as the basic understanding of manganese dissolution and oxygen defects may open new opportunities toward high‐performance aqueous ZIBs.

AbstractMultifunctional nanodrugs integrating multiple therapeutic and imaging functions may find tremendous biomedical applications. However, the development of a simple yet potent theranostic nanosystem with a high payload and microenvironment responsiveness enhancing imaging‐guided cancer therapy is still a great challenge. Herein, a kind of MnCO‐entrapped mesoporous polydopamine nanoparticles are developed, which reach a 1.5 mg payload per gram carrier and exhibit marked theranostic capability through effective CO/Mn2+ generation and photothermal conversion inside the H+ and H2O2‐enriched tumor microenvironment, for a magnetic resonance/photoacoustic bimodal imaging‐guided tumor therapy. The multifunctional nanosystem exhibits a biocompatibility highly desirable for in vivo application and superior performance in inhibiting tumor growth and recurrence via combination CO and photothermal therapy.

Published: February 2019

AbstractCompared to the most studied 2D elements and binary compounds, ternary layered compounds with more adjustable physical and chemical properties have exhibited potential applications in electronic and optoelectronic devices. Here, 2D ternary layered BiOI crystals are synthesized first with a domain size up to 100 µm via space‐confined chemical vapor deposition. The photodetectors based on the as‐grown BiOI nanosheets demonstrate high sensitivity to 473 nm light. The Ion/Ioff ratio and detectivity of BiOI photodetectors can reach up to 1 × 105 and 8.2 × 1011 Jones at 473 nm, respectively. Particularly, the contact and dark current of the photodetectors can be controlled by 254 nm ultraviolet light irradiation due to the introduction of oxygen vacancies. The facile synthesis of large‐area atomically thin BiOI and its controllable performance by ultraviolet light irradiation suggest that 2D BiOI crystal is a promising material for fundamental investigations and optoelectronic applications.

AbstractEfficient cleanup of viscous crude oil spill is a worldwide challenge due to its sluggish flowability at room temperature. Conventional oil remediation methods using physical absorbers, skimmers, and vacuum technologies either demonstrate low absorption efficiency or have severe operational restrictions. Inspired by the highly efficient and passive transpiration process in trees, a solar‐heated carbon absorber (HC‐Wood) with an inherited wood structure of aligned channels for rapid crude oil absorption is reported. The unique porous structure of the carbon absorber can extend the light absorption paths, guide the direction of heat transport, and decrease the resistance to oil flows, endowing the carbon absorber a large efficiency of solar absorption (>99% of the incident irradiation), excellent thermal management, and fast capillarity‐driven oil absorption behavior. The low tortuosity of the porous structure together with the efficient solar‐thermal conversion enable the absorber to demonstrate a crude oil absorption rate of 1550 mL m−2 in 30 s under 1 sun irradiation, which is 10 times faster than previously reported results for passive absorption of viscous crude oil. Given the unique structural design, low operating cost, and rapid oil absorption speed, this work provides a promising solution for addressing catastrophic large‐area viscous oil spills.

AbstractPerovskite solar cells (PSCs) have advanced rapidly with power conversion efficiencies (PCEs) now exceeding 22%. Due to the long diffusion lengths of charge carriers in the photoactive layer, a PSC device architecture comprising an electron‐ transporting layer (ETL) is essential to optimize charge flow and collection for maximum performance. Here, a novel approach is reported to low temperature, solution‐processed ZnO ETLs for PSCs using combustion synthesis. Due to the intrinsic passivation effects, high crystallinity, matched energy levels, ideal surface topography, and good chemical compatibility with the perovskite layer, this combustion‐derived ZnO enables PCEs approaching 17–20% for three types of perovskite materials systems with no need for ETL doping or surface functionalization.

AbstractFabrication of flexible and free‐standing graphene‐fiber‐ (GF‐) based microelectrode arrays with a thin platinum coating, acting as a current collector, results in a structure with low impedance, high surface area, and excellent electrochemical properties. This modification results in a strong synergistic effect between these two constituents leading to a robust and superior hybrid material with better performance than either graphene electrodes or Pt electrodes. The low impedance and porous structure of the GF results in an unrivalled charge injection capacity of 10.34 mC cm−2with the ability to record and detect neuronal activity. Furthermore, the thin Pt layer transfers the collected signals along the microelectrode efficiently. In vivo studies show that microelectrodes implanted in the rat cerebral cortex can detect neuronal activity with remarkably high signal‐to‐noise ratio (SNR) of 9.2 dB in an area as small as an individual neuron.
Synthetic Hilbert Space Engineering of Molecular Qudits: Isotopologue Chemistry
Authors: Wernsdorfer Wolfgang , Ruben Mario 
Published: February 2019

AbstractOne of the most ambitious technological goals is the development of devices working under the laws of quantum mechanics. Among others, an important challenge to be resolved on the way to such breakthrough technology concerns the scalability of the available Hilbert space. Recently, proof‐of‐principle experiments were reported, in which the implementation of quantum algorithms (the Grover's search algorithm, iSWAP‐gate, etc.) in a single‐molecule nuclear spin qudit (with d = 4) known as 159TbPc2 was described, where the nuclear spins of lanthanides are used as a quantum register to execute simple quantum algorithms. In this progress report, the goal of linear and exponential up‐scalability of the available Hilbert space expressed by the qudit‐dimension “d” is addressed by synthesizing lanthanide metal complexes as quantum computing hardware. The synthesis of multinuclear large‐Hilbert‐space complexes has to be carried out under strict control of the nuclear spin degree of freedom leading to isotopologues, whereby electronic coupling between several nuclear spin units will exponentially extend the Hilbert space available for quantum information processing. Thus, improved multilevel spin qudits can be achieved that exhibit an exponentially scalable Hilbert space to enable high‐performance quantum computing and information storage.
Rechargeable Aqueous Electrochromic Batteries Utilizing Ti‐Substituted Tungsten Molybdenum Oxide Based Zn2+ Ion Intercalation Cathodes

Published: February 2019

AbstractBatteries are used in every facet of human lives. Desirable battery architectures demand high capacity, rechargeability, rapid charging speed, and cycling stability, all within an environmentally friendly platform. Many applications are limited by opaque batteries; thus, new functionalities can be unlocked by introducing transparent battery architectures. This can be achieved by incorporating electrochromic and energy storage functions. Transparent electrochromic batteries enable new applications, including variable optical attenuators, optical switches, addressable displays, touch screen devices, and most importantly smart windows for energy‐efficient buildings. However, this technology is in the incipient state due to limited electrochromic materials having satisfactory optical contrast and capacity. As such, triggering electrochromism via Zn2+ intercalation is advantageous: Zn is abundant, safe, easily processed in aqueous electrolytes and provides two electrons during redox reactions. Here, enhanced Zn2+ intercalation is demonstrated in Ti‐substituted tungsten molybdenum oxide, yielding improved capacity and electrochromic performance. This technique is employed to engineer cathodes exhibiting an areal capacity of 260 mAh m−2 and high optical contrast (76%), utilized in the fabrication of aqueous Zn‐ion electrochromic batteries. Remarkably, these batteries can be charged by external voltages and self‐recharged by spontaneously extracting Zn2+, providing a new technology for practical electrochromic devices.
