Published: December 2024

Soot is a short-lived climate forcing agent whose warming potential varies significantly during its atmospheric lifetime. The particles of soot have a complex fractal morphology, but in atmospheric aerosol models they are commonly represented as spheres. We show that taking the fractal morphology into consideration significantly accelerates the rate of aging of soot aerosol in the atmosphere because concave surfaces in fractal particles promote rapid capillary condensation of trace gas chemicals produced from the photochemical oxidation of volatile organic compounds, even when vapors of such chemicals are subsaturated. Our results suggest that by capillary condensation alone these chemicals can transform hydrophobic soot particles into cloud condensation nuclei within a few hours. Additionally, capillary condensation induces compaction of fractal soot even at a moderately elevated relative humidity, changing its transport and optical properties. Representing an important mechanism of atmospheric aging, capillary condensation has a profound effect on the evolution of direct and indirect climate impacts of soot, at a higher rate than previously recognized, and hence it must be incorporated into atmospheric aerosol models to improve their predictive power.

Published: December 2024

The preparation of regioisomers of small molecules is routine, but an analogous concept of positional isomerism is absent for extended materials. Crystalline frameworks such as zeolites and metal-organic frameworks (MOFs) can furnish well-defined active sites for heterogeneous catalysis, but their arrangement cannot be tuned in isolation. Here we show that a mobility-tuned synthesis approach permits selective synthesis of multiple different “structomers”, which are isostructural and compositionally identical but which feature different metal arrangements. High-fidelity access to each targeted metal arrangement was confirmed by operationally facile electron paramagnetic resonance analysis and validated by mass spectrometry. The performance of Rh centers in propene hydrogenation catalysis differs substantially for different metal arrangements within the framework, even though all Rh centers have identical primary coordination environments. For properties that depend on metal distances, structomer-selective synthesis thus presents a new paradigm for fundamental study and performance optimization.

Authors: Ren Yu-Feng , Chen Jin-Kui , Shu Wei
Published: December 2024

Allylic ethers are important functional motifs widespread in bioactive molecules and natural products and serve as versatile synthetic intermediates for value-added target molecules. Therefore, developing general and direct methods to allylic ethers from feedstocks is highly desirable. Direct cross-coupling of alkenes with free alcohols by allylic C-H functionalization under mild conditions represents the most ideal way for the synthesis of branched allylic ethers. Herein, a dual catalysis of visible-light and cobaloxime enables allylic C-H direct oxygenation of alkenes with alcohols to afford branched allylic ethers has been developed. Notably, exclusive regio- and chemoselective mono-etherification of C-H bond to give branched allylic ethers with primary, secondary, and tertiary free alcohols. Moreover, other oxygen-based nucleophiles, such as carboxylate and cyclic 1,3-diketones, are also compatible in the reaction, providing a mild and robust allylic oxygenation of more steric hindered C-H from easily available alkenes.

Authors: Gosselin Bryan , Dutour Raphael , Jabin Ivan , Bruylants Gilles
Published: December 2024

This study explores the use of lateral flow assays (LFAs), recognized for their simplicity and ease-of-use, as a tool for characterizing nanoparticles functionalized with various biomolecules (e.g., proteins, antibodies and nucleic acids). A half-strip model system was developed using ovalbumin (OVA) conjugated to gold nanoparticles (AuNPs). The characterization results obtained with LFAs were compared to those from traditional methods such as infrared spectroscopy and fluorescence labelling. The advantages of LFAs in characterizing such conjugated nanosystems were clearly demonstrated. The use of half-strip assays could not only confirm the presence of OVA on AuNPs but also enable the quantification of OVA bound per nanoparticle, offering a rapid and quantitative characterization method. Additionally, the assay showcased its versatility, as it was successfully applied to optimize the covalent coupling conditions of OVA on AuNPs, as well as to differentiate between covalently bound and adsorbed proteins. Furthermore, LFAs were employed to detect antibodies on functionalized nanoparticles, optimize their coupling to a newly developed organic coating, and confirm both the grafting of nucleic acids onto the surface and their pairing with complementary strands. These findings underscore the remarkable adaptability of LFAs for characterizing diverse nanoconjugates. Overall, LFAs stand out as a versatile and accessible tool for characterizing complex bioconjugated nanosystems, making them highly suitable for rapid Quality Control (QC) analysis and bioconjugation optimization.

Authors: Wheeler Mikhailey , Clark Allison , Kinsman Andrew , Kerton Francesca
Published: December 2024

Sustainable materials are a large research focus due to depleting resources and increasing environmental pollution. Therefore, bio-derived building blocks from renewable feedstocks are being pursued as an alternative to fossil-derivatives for producing polymers. Here, we have prepared a series of polyester and polyester-block-polycarbonate copolymers from a metal-free ring-opening copolymerization (ROCOP) of various terpene-derived cyclic anhydrides, epoxides (cyclohexene oxide (CHO) and propylene oxide (PO)), and carbon dioxide (CO2) under neat (solvent-free) conditions. Cyclic anhydrides were prepared via microwave-assisted Diels Alder reactions between terpenes and maleic anhydride (up to 90% yield). The ROCOP catalyst system consisted of triphenylborane (BPh3) with bis(triphenylphosphine)iminium chloride (PPNCl) and, after complete conversion of anhydride, resulted in polymers with moderate molecular weights (Mn up to 21 kDa), and good dispersities (between 1.05 and 1.75). Thermal analysis resulted in a single glass transition temperature (between 1.5 C and 101 C) indicating amorphic materials. 13C{1H} NMR spectroscopy revealed high stereoregularity with respect to substituent methyl groups and di-ester units and 2D DOSY NMR spectroscopy confirmed a single polymer chain was formed by sequential copolymerizations. Residual olefinic groups in the polymer backbone provides opportunity for post-polymerization functionalization and, therefore, further tailoring of macroscopic properties.
Downsizing Lactams via Rh-Catalyzed C–C Activation
Authors: Zhang Rui , Wen Kangmin , Dong Guangbin
Published: December 2024

Ring-contraction reactions are valuable transformations to access harder-to-synthesize smaller-sized rings from more available larger-sized precursors. Herein, we report an unprecedented lactam downsizing strategy by taking advantage of removable directing groups (DGs) and Rh-catalyzed C–C activation. A mild method for DG installation to common lactam substrates is developed by employing silylated amines and Ti catalysts, and the resulting amidine moiety can be converted back to lactams via acid mediated hydrolysis. The ring-contraction reaction exhibits a broad substrate scope, excellent functional group tolerance, and high selectivity for yielding γ-lactams, facilitating “6-to-5”, “7-to-5”, and “8-to-5” ring contractions. Additionally, through careful selection of DGs and ligands, preliminary results on selective “7-to-6” ring contraction has been obtained. Finally, density functional theory (DFT) calculations reveal the origin of the product selectivity.

Published: December 2024

Strained, multicyclic hydrocarbons are increasingly important structural motifs for drug discovery. In particular, substituted bicyclo[1.1.1]pentanes (BCPs) have risen to prominence as bioisosteres for the ubiquitous benzene ring. Despite their favorable pharmacokinetic properties, synthetic strategies towards BCPs suffer from significant drawbacks – namely an overreliance on [1.1.1]propellane – an operationally challenging starting material which complicates scale-up and hampers widespread adoption of these motifs. In this work, the synthesis of 2,2-dibromo BCPs is described, presenting a class of novel substituted BCPs and circumventing the need for [1.1.1]propellane-based precursors. Scalable access to these compounds is demonstrated in a simple and inexpensive process, and their applicability for medicinal chemistry campaigns is highlighted, including through development of an electrochemical method for BCP bridge arylation to afford direct access to valuable BCP building blocks.
Electronic Structure and Adsorption Stability of Ferrocene on Au (111) and Ag (111) Surfaces
Authors: Li Shuhao , Li Chunqing , Wang Feng
Published: December 2024

The adsorption behavior and electronic structure of ferrocene (Fc) on Au(111) and Ag(111) surfaces were investigated using density functional theory (DFT). Two Fc conformers, eclipsed (E-Fc) and staggered (S-Fc), were studied in vertical (⏊) and parallel (||) orientations at three adsorption sites—top (T), hollow (H), and bridge (B). Fc preferentially adsorbs in a vertical configuration through the lower Cp ring on hollow sites, with adsorption energies of -0.87 eV (E-Fc) and -0.88 eV (S-Fc) on Au(111) and -0.79 eV for both conformers on Ag(111). These results confirm that Fc adsorptions are more stable on Au(111) than Ag(111), with negligible stability differences between the two conformers in vertical configurations. Parallel configurations are generally less stable; S-Fc cannot stably adsorb parallel on either surface, and E-Fc(||) exhibits significantly weaker adsorption energies (-0.82 eV on Au(111) and -0.62 eV on Ag(111)) than vertical configurations. Electronic structure analysis reveals that Fc acts predominantly as an electron donor on both metal surfaces. A distinctive region-specific charge transfer is observed in vertical configurations, where electrons flow from top-layer Au atoms to the Cp ring of Fc, forming an electron circuit that enhances adsorption strength. This feature is absent in parallel configurations, where charge transfer occurs uniformly from Fc to the surface, resulting in weaker adsorption. These findings underscore the impact of adsorption geometry and surface type on Fc’s stability and electronic interactions, offering valuable insights into its behavior on metallic surfaces. While results for Fc/Ag(111) are included in supplementary materials, the primary focus is on Fc/Au(111). This study provides a basis for exploring Fc-surface interactions in applications such as corrosion inhibition and catalysis.
Properties of o-Carborane Triads: Non-covalent σ…π Interactions and Intermolecular Charge Transfer
Authors: Zhang Yang , Lalancette Roger , Galoppini Elena
Published: December 2024

Two ortho-carborane triads, p-BrPh-oCB-PhEPy (3), where p-BrPh is p-bromobenzene, and DMA-oCB-PhEPy (4), where DMA is p-N,N-dimethylaniline, PhEPy is 1-(p-phenylethynyl)pyrene, were studied in solution, as single crystals, and in the solid state (photophysical measurements). Both compounds exhibited aggregation-induced emission (in solution, or in the solid state). The crystal structures of both triads exhibit interactions between pyrene units and the carborane (CB) moiety, resulting in intermolecular charge-transfer between the pyrene units and the o-carborane moiety. This interaction significantly influences crystallization, leading to distinctive crystallographic packing patterns. Remarkably, these molecules display multiple emissive species, positioning them as potential candidates for single molecule white-light emission and thermally-activated delayed fluorescence (TADF).
Linear-Scaling Local Natural Orbital-based Full Triples Treatment in Coupled-Cluster Theory
Authors: Jiang Andy , Schaefer III Henry , Turney Justin
Published: December 2024

We present an efficient, asymptotically linear-scaling implementation of the canonically O(N^8) coupled-cluster method with singles, doubles, and full triples excitations (CCSDT) method. We apply the domain-based local pair natural orbital (DLPNO) approach for computing CCSDT amplitudes. Our method, called DLPNO-CCSDT, uses the converged coupled-cluster amplitudes from a preceding DLPNO-CCSD(T) computation as a starting point for the solution of the CCSDT equations in the local natural orbital basis. To simplify the working equations, we t1-dress our two-electron integrals and Fock matrices, allowing our equations to take on the form of CCDT. With appropriate parameters, our method can recover more than 99.99% of the total canonical CCSDT correlation energy. In addition, we demonstrate that our method consistently yields sub-kJ mol^-1 errors in relative energies when compared to canonical CCSDT, and, likewise, when computing the difference between CCSDT and CCSD(T). Finally, to highlight the low scaling of our algorithm, we present timings on linear alkanes (up to 30 carbons and 730 basis functions) and water clusters (up to 131 water molecules and 3144 basis functions).
Accounting for the Vibrational Contribution to the Configurational Entropy in Disordered Solids with Machine Learned Forcefields: A Case Study of Garnet Electrolyte Li7La3Zr2O12
Authors: Yang Jack , Yin Ziqi , Li Sean
Published: December 2024

Accounting for lattice vibrations to accurately determine the phase stabilities of site-disordered solids is a long-standing challenge in computational material designs, due to the high computational cost associated with sampling the vast configurational space to obtain the converged thermodynamic quantities. One example is the garnet electrolyte Li7La3Zr2O12, the high-temperature and high-ion-mobility cubic phase of which is disordered in its Li+ site occupations, such that both the vibrational and configurational entropic contributions to its phase stability cannot be ignored. Understanding the subtle interplay between vibrational and configurational entropies in this material will therefore play a critical role in the rational manipulation of dopants and defects to stabilise cubic Li7La3Zr2O12 at room temperature for practical applications. Here, by developing machine learned forcefields based on an equivariant message-passing neural network SO3krates, we follow a strict statistical thermodynamic protocol to quantify the phase stability of cubic Li7La3Zr2O12 through structural optimisations, as well as molecular dynamic simulations at 300 and 1500 K, for a total of 70,120 configurations of cubic Li7La3Zr2O12. Although this only covers a tiny fraction of the configurational space (7x10^34 configurations in total), we are able to deterministically show the vibrational contributions to the total configurational free energy at 1500 K are significant (on the order of 1 eV/atom) in correctly ordering the stability of the cubic Li7La3Zr2O12 over its tetragonal counterpart, thanks to the high data efficiency, accuracy, stability and good transferability of the transformer-based equivariant network architecture behind SO3krates. Therefore, our work opens up new avenue to accelerate the accurate computational designs of disordered solids, such as solid electrolytes, for technologically important applications.

Numerical investigation of electrocoalescence-induced fluid demixing between parallel plates
Authors: Tiktaş Aslı
Published: December 2024

The efficient separation of dispersed phase droplets from a continuous phase in multiphase flow systems is essential for industries such as petroleum refining, pharmaceuticals, and food production. Conventional methods, relying on gravitational and buoyancy forces, are often inadequate for small droplets due to their weak influence. Electrocoalescence, utilizing electrical forces to enhance droplet coalescence, has gained attention as a promising alternative. However, most studies have focused on simplified models, limited electrical potentials, or axis-symmetric configurations, overlooking the effects of varying electrical potentials on droplet behavior in complex flows. This study bridges that gap by developing a numerical solver that couples the phase-field method with the Navier-Stokes equations to simulate electrocoalescence of two-dimensional droplets in laminar phase flow between parallel plates. The solver provides detailed insights into multiphase flow dynamics, including contact line behavior and interface tracking under different electrical potentials. The novelty of this work lies in its systematic evaluation of how varying electrical potentials affect droplet deformation, separation time, and interface dynamics, which are often not fully addressed by standard commercial solvers. The findings indicated that increasing electrical potentials from 50 kV to 100 kV leads to droplet deformation, with the droplet deformation index (DDI) increasing from 0.35 to 0.52. Additionally, phase separation time decreases by 20%, from 0.15 seconds to 0.12 seconds, as electrical potential increases. The increasing electrical potentials lead to asymmetric droplet shapes and instability, accelerating separation by disrupting the formation of stable liquid bridges. These findings offer valuable insights into optimizing electrocoalescence processes for industrial applications. In this study, a multi-objective optimization process was conducted using the Non-dominated Sorting Genetic Algorithm II (NSGA-II), with the aim of minimizing droplet deformation and phase separation time. The optimization results revealed that the ideal initial contact angle for minimizing deformation was 123.45°, while the optimal contact angle for minimizing separation time was 145.67°. These results highlight the potential of optimizing system parameters to improve the efficiency and stability of electrocoalescence processes in various industrial applications.The current study provides a deeper understanding of the interaction between electrical forces and multiphase flow dynamics, laying the groundwork for advancements in phase separation technologies across various industries.

DIFFERENCE SEXUELLE: CIXOUS, DERRIDA
Authors: Ruiz Bustamante Carmen
Published: December 2024

Dans cet article, je passe en revue quelques réflexions d’Hélène Cixous sur la différence sexuelle, dans le but de montrer que dans ses essais des années 1970, on peut trouver des éléments autour de la question du genre qui permettent de pousser plus loin les réflexions de Derrida sur le phallogocentrisme. En montrant la complexité et l’hétérogénéité de ses réflexions, qui ne sont pas toujours en accord les unes avec les autres, mon intérêt est de montrer la voie que Cixous ouvrirait à la déconstruction du phallogocentrisme, lorsqu’elle invite à remarquer le caractère androcentrique du désir de présence qui sous-tend la métaphysique.

Where Is My Country?: From Everyday Life to the Emigration Complex in Brian Friel’s Philadelphia, Here I Come!
Authors:   The Education University of Hong Kong, Chang Hawk
Published: December 2024

Arguably, Brian Friel’s 1964 work Philadelphia, Here I Come! is one of the most influential
plays in 20th-century Irish literature, as it focuses on emigration, a pivotal political and
cultural phenomenon that recurs in both modern and contemporary Irish history. Crucially,
Friel invents a protagonist with split personalities, Public Gar and Private Gar, representing
the conflicted mentality of a migrant who finds it necessary to leave their motherland.
By reading Friel’s Philadelphia, Here I Come! from the perspective of migration, this paper
examines the necessity of departure for Gar and the difficulty of his arrival. I argue that Gar’s
conflicts are not accidental but are consistent with a typical Irish mentality. However, the
play suggests that the Irish protagonist’s endeavor to shun troubles via voluntary emigration
can hardly promise a better tomorrow.

É consenso global e nacional a necessidade de reinvenção coletiva para promoção de um futuro mais justo e sustentável e a educação tem importância primordial nesse processo. Para transformar escolas em locais educacionais protegidos, inclusivos, promotores de equidade, bem-estar individual e coletivo, é preciso repensar a educação atual para transformar o mundo em um lugar mais justo, equitativo e sustentável. Os desafios de implementação e aprimoramento educacional são proporcionais a diversidade da realidade brasileira. O trabalho em questão se propõe a realizar uma pesquisa documental acompanhando o estabelecimento das metas brasileiras e suas estratégias. Por meio de um estudo comparativo identificamos as estratégias descritas no contexto mundial a partir das diretrizes da UNESCO em relação às nacionais, descritas nos indicadores brasileiros dos Objetivos de Desenvolvimento Sustentável 4 (ODS4) e finalmente, associamos a inclusão, prevista na Meta IV do Plano Nacional de Educação. Concluímos que as metas brasileiras estão alinhadas às proposições globais, com as devidas adequações mediante seus recursos econômicos, políticos e sociais.

Este estudo tem como objetivo analisar os desafios e as possibilidades da pedagogia freireana na construção de práticas pedagógicas na Educação Infantil, tendo como norte a seguinte questão norteadora: quais as contribuições de Paulo Freire para o processo educativo de crianças sob uma perspectiva da Alfabetização Científica? O trabalho articula saberes populares e conhecimentos científicos no contexto da Educação Infantil e da realidade local. Para tanto, a metodologia da pesquisa, de caráter qualitativo, foi organizada em duas fases: a primeira de caráter teórico em que parte de estudos bibliográficos sobre as articulações entre a pedagogia freireana, a Alfabetização Científica, e a Educação Infantil. E a segunda, de caráter empírico, em que, a partir de um curso formativo com educadores(as) de uma escola municipal do Alto Sertão Alagoano foi realizado o processo de Investigação Temática para localização de problemas vivenciados pela comunidade, servindo como ponto de partida para elaboração das propostas pedagógicas. Como objeto de análise, tomou-se duas propostas educativas de um Caderno de Atividades, baseado em um Tema Gerador, o qual contempla temáticas sobre: “Práticas de plantio” e “A água e o cultivo de alimentos”. Dentre os resultados, foi identificado que as ideias de Paulo Freire demonstraram contribuir para a (re)invenção de um trabalho pedagógico com as crianças, que tenha como mote sua emancipação e não sua domesticação. E, pela interação entre educadores(as)/crianças e crianças entre crianças é fortalecido processos de construção de leituras compartilhadas dos contextos sociais e culturais em que estes sujeitos se inserem de modo a transformar a si próprios(as) e o seu mundo.

A viticultura brasileira apresenta uma enorme gama de variedades e de regiões produtoras. A variedade ‘Bordô’ possui destaque na produção nacional dada a sua destinação para a produção de vinhos de mesa tintos e sucos naturais, que possuem mais apreço pelos brasileiros. A região do Planalto Norte Catarinense possui condições edafoclimáticas favoráveis para a viticultura, entretanto, carece de informações sobre o manejo necessário na região. Com isso, o presente ensaio buscou avaliar o efeito do manejo da desfolha da no desempenho agronômico da videira ‘Bordô’ cultivada no planalto norte catarinense. Para isso foram realizados cinco tratamentos, determinados em blocos ao acaso, que consistiam em diferentes épocas de desfolha, sendo eles, T1 = Plena florada, T2 = Grão chumbinho, T3 = Grão ervilha, T4 = Mudança de cor e T5 = Testemunha. O trabalho foi realizado no município de Canoinhas/SC, em vinhedo comercial de variedade Bordô sob porta enxerto “VR 043-43”, com espaçamento 3,0 x 1,5 m, conduzidas em manjedoura, em sistema de poda mista, no ciclo 2022/2023. Foram avaliadas as variáveis massa de cacho, comprimento do cacho, número de bagas por cacho, o diâmetro de baga, índice de compactação, massa de 50 bagas, sólidos solúveis, acidez total titulável e pH. Dentre as variáveis analisadas, o tratamento T5 apresentou maior massa de cacho e pH, a massa de 50 bagas obteve menores valores em grão chumbinho e grão ervilha, enquanto os tratamentos T3 e T4 apresentaram maior acidez total. Com isso, verifica-se que o manejo da desfolha em conjunto com o desponte padrão resulta em uma redução excessiva da área foliar, ocasionando pouca ou nenhuma interferência nas variáveis analisadas. Dessa forma, novos ensaios de desfolha associados ou não a outros manejos do dossel vegetativo devem ser realizados na região.

Os meios de cultura são preparações que contém as fontes nutricionais necessárias para o crescimento e multiplicação de organismos, devendo suprir as necessidades mínimas para cultivo in vitro. Teve-se como objetivo comparar diferentes meios de cultura tendo tubérculo como fonte principal de nutrientes no crescimento de Fusarium sp. Os tubérculos foram adquiridos no mercado popular e foram utilizados, individualmente, para preparação dos meios de culturas. O diâmetro das colônias foi avaliado diariamente tomado no reverso das placas, através da mensuração, em dois sentidos, dos diâmetros perpendiculares. O delineamento experimental foi inteiramente casualizado, 4 tratamentos e 6 repetições. Os dados obtidos foram submetidos à análise de variância (ANOVA) e as médias comparadas pelo Teste de Tukey em nível de 5% de probabilidade. Em todos os meios ocorreu esporulação. O meio de batata-doce promoveu maior velocidade de crescimento micelial.

A couve-manteiga (Brassica oleracea L. var. Acephala), pertencente à família Brassicaceae, é uma cultura que possui grande valor econômico, no entanto, a qualidade e produtividade do cultivo de couve-manteiga pode ser afetada devido a ocorrência de surtos populacionais de insetos praga. Dentre os insetos praga associados a cultura da couve, destaca-se a Ascia monuste orseis (Latrielle, 1819) (Lepidoptera: Pieridae), conhecida popularmente como curuquerê-da-couve. Atualmente, a maneira mais utilizável de reduzir as populações desse inseto-praga é através do uso periódico de inseticidas químicos, porém o controle químico traz efeitos deletérios, tais como a contaminação ambiental e o risco à saúde humana. Uma alternativa que vem sendo foco de pesquisas é o uso do controle comportamental, através do uso de semioquímicos com a utilização de plantas armadilhas (interação inseto/planta). Diante disso, esse trabalho teve como objetivo avaliar a preferência de oviposição de A. monustes orseis entre B. oleracea var. acephala e C. spinosa (mussambê), com o  uso de plantas armadilhas. A pesquisa foi desenvolvida em condições de campo, nas dependências do Laboratório de Entomologia Agrícola e Florestal (LEAF). O experimento ocorreu entre o mês de setembro a outubro de 2024, as avaliações foram feitas a cada 3 dias, totalizando 10 avaliações. Em números totais ocorreram 29 posturas e 689 ovos ao longo das 10 avaliações, sendo 28 posturas e 677 ovos apenas no mussambê. Sendo assim, o mussambê possívelmente apresenta compostos volatéis que atuam como aleloquímicos na atratividade da A. monuste orseis, tornando essa espécie um hospedeiro alternativo a ser utilizado como planta armadilha no manejo da praga em cultivos B. oleracea var. acephala.
