Unique Phosphorus-based Avenues for the Tuning of Functional Materials
(American Chemical Society, 2023-03-07) Asok, Nayanthara; Gaffen, Joshua R.; Baumgartner, Thomas
Recent ground-breaking advances in synthetic chemistry have transformed main-group molecules from simple lab curiosities into powerful materials for a range of applications in all realms of life. Electron-accepting or -deficient materials in particular, have been the focus for development since their generally limited availability and stability have been a key limiting factor towards establishing new practical applications. In addition to the general requirements for the design of these materials, a deeper understanding of their inherent electronics and molecular interactions is a requisite for the successful expansion of their utility. Previously, the incorporation of electron-deficient main-group elements, such as boron into a conjugated organic framework was considered an effective route toward the synthesis of high-performing electron-accepting materials. However, challenging conditions such as the need for bulky substituents for kinetic stabilization, air-free, and moisture-sensitive synthesis, and restricted storage abilities have led to the investigation of other elements across the periodic table to be used in a similar vein. Lately, heavier main-group elements such as Si, Ge, P, As, Sb, Bi, S, Se, and Te have also proven to be advantageous for electron-accepting materials as they exhibit polarizable molecular orbitals that are easily accessible to electrons or nucleophiles. This has laid the foundation for materials chemistry research on a variety of applications including, optoelectronic devices such as OLEDs, organic photovoltaics, energy storage such as batteries and capacitors, fluorescent sensors with both biological and physiological applications, organocatalysis and synthesis, and many more. Among the main group element-based materials, organophosphorus species are privileged as their frontier orbitals are easily altered by chemical modification or/and structural and geometrical manipulations at the phosphorus center itself, without the need for kinetic stabilization, or through electronic modification of the conjugated system. The five-membered phosphorus-based heterocycle, phosphole, is a particularly interesting motif in this context and extensive studies on the corresponding materials have uncovered the rich fundamentals of the σ*-π* interaction that imparts intriguing accepting properties, while sustaining morphological and physiological stability for utilization in real-life scenarios. Moreover, beyond the σ*-π* interaction in phospholes that is key to many of their acceptor properties as a material, the use of phosphorus also gives rise to easily accessible, low-lying antibonding orbitals. They pave the way toward Lewis acidic phosphorus species that, despite being considered as electron-rich species in general, open up several possibilities for intriguing chemical reactivity through hypervalency. Herein, we representatively discuss some recent advancements through the various approaches that leverage the unique structures and electronics of organophosphorus species toward the design of materials with outstanding electronic, chemical, and structural properties and reactivities for the functional material world.
Black Movement and Freedom: Questions of Cyclescapes, Cycling Planning, and Minstrelsy
(2025-04-30) Ismail, Sabat; Ali, Muna-Udbi
This paper investigates the following central question: What are the outcomes of the historical and ongoing restrictions placed upon the Black diaspora's physical movement? Related to my research question, I consider what the literature and archives have to say about Black experiences with movement and I engage with cycling-related scholarship on class and race, particularly as it relates to Black communities. I explore this in this paper to sufficiently contextualize the subject-matter I am engaging with. I argue that the historical and ongoing restrictions of the movement of the Black diaspora is subjectivity-producing and provides an alternative lens to better understanding anti-Blackness, and liberatory ways of understanding and engaging with movement. Additionally, to contribute to advancing an underexplored research topic in Black Geographies and further the growing scholarship on cycling and racism. Additionally, I explore the experiences of cycling and Black communities and conduct a research analysis on late nineteenth-century minstrel and other anti-Black imagery featuring bicycles. This paper focuses on Canada and the United States, bringing cycling and transportation research into conversation with Black studies and Black geographies. I draw on archival materials from the late 1800s to early 1900s, alongside a counter-archival and discourse analysis. My sources include journalism, transportation planning data, and academic literature in social geography, anthropology, and history—all centred on cycling in North America.
Water chemistry and sediment core data from small, shallow lakes of the Taiga Plains (Northwest Territories, Canada)
(2025) Korosi, Jennifer; Coleman, Kristen; Thienpont, Joshua; Palmer, Michael
Lake browning has been widely projected for northern lakes affected by permafrost thaw, but the inherent heterogeneity in permafrost landscapes coupled with a paucity of data for many regions makes it challenging to develop circumpolar-scale assessments. This dataset provides surface water chemistry from 35 small, shallow (0.5-3 m) lakes in discontinuous permafrost peatlands of the Taiga Plains (Northwest Territories, Canada), which were distributed across two Level IV ecoregions (Cameron Uplands, Tathlina Plain). This dataset also provides a comparison subfossil diatom assemblages between present-day (2012-2018) and ~1850 in 23 Taiga Plains lakes distributed across three Level IV ecoregions (Cameron Uplands, Tathlina Plain, South Mackenzie Plain).
‘Homing’ and the Desire for ‘Homing’: Reading/Teaching Kamila Shamshie’s Kartography Through a Migrant’s Experience
(Mahanirban Calcutta Research Group, 2024-12) Bhattacharya, Indira Chakraborty
The first attempt that one should make while talking about Refugee Studies or Migration Studies especially while teaching to any group of migrant youngsters about any particular text is to define under which category does that particular text fall, i.e., whether the text has been written by any migrant author who pens his/her experience as a migrant, or the content of the text is about migrants and their experiences in a particular place. The texts are roughly classified by scholars as into sub-categories of Migration Literature or "Ecriture Migrante/Ecriture Immigrantes" within the discipline of Literature. In a classroom before teaching these migrant texts it is necessary to build trust between the migrant student, the institutional system and the teacher to develop a sense of inclusivity that might make the migrant student a little more comfortable about reading migrant literatures and corelate with its relevance.
A quantum Murnaghan--Nakayama rule for the flag manifold
(2024-06-08) Benedetti, Carolina; Bergeron, Nantel; Colmenarejo, Laura; Saliola, Franco; Sottile, Frank
In this paper, we give a rule for the multiplication of a Schubert class by a tautological class in the (small) quantum cohomology ring of the flag manifold. As an intermediate step, we establish a formula for the multiplication of a Schubert class by a quantum Schur polynomial indexed by a hook partition. This entails a detailed analysis of chains and intervals in the quantum Bruhat order. This analysis allows us to use results of Leung--Li and of Postnikov to reduce quantum products by hook Schur polynomials to the (known) classical product.
