A question of belonging: Reading Jean Arasanayagam through nationalist discourse

Jean Arasanayagam's writing, arising from a unique confluence of what can be considered minoritized identities in Sri Lanka (Burgher and Tamil), provides critical insights into the ways in which a marginalized consciousness seeks to carve a niche for itself within an exclusive, majoritarian nationalist discourse. Such minority self-fashioning is often seen in terms of a paradigm of resistance that deconstructs the dominant or hegemonic national discourse and renders identity mobile and fluid. However, we argue that Arasanayagam's writing, rather than being "post-national", is heavily invested in the idea of national belonging. Through close readings of a selection of poems, drawn from her earliest published work to recent writing, we explore the ambiguities and contradictions arising out of Arasanayagam's desire for a self-identity in what can be loosely termed a Sri Lankan national imaginary.

Data_Sheet_1_Ligand Structure Determines Nanoparticles' Atomic Structure, Metal-Ligand Interface and Properties.PDF

<p>The nature of the ligands dictates the composition, molecular formulae, atomic structure and the physical properties of thiolate protected gold nanomolecules, Au_n(SR)_m. In this review, we describe the ligand effect for three classes of thiols namely, aliphatic, AL or aliphatic-like, aromatic, AR, or bulky, BU thiol ligands. The ligand effect is demonstrated using three experimental setups namely: (1) The nanomolecule series obtained by direct synthesis using AL, AR, and BU ligands; (2) Molecular conversion and interconversion between Au₃₈(S-AL)₂₄, Au₃₆(S-AR)₂₄, and Au₃₀(S-BU)₁₈ nanomolecules; and (3) Synthesis of Au₃₈, Au₃₆, and Au₃₀ nanomolecules from one precursor Au_n(S-glutathione)_m upon reacting with AL, AR, and BU ligands. These nanomolecules possess unique geometric core structure, metal-ligand staple interface, optical and electrochemical properties. The results unequivocally demonstrate that the ligand structure determines the nanomolecules' atomic structure, metal-ligand interface and properties. The direct synthesis approach reveals that AL, AR, and BU ligands form nanomolecules with unique atomic structure and composition. Similarly, the nature of the ligand plays a pivotal role and has a significant impact on the passivated systems such as metal nanoparticles, quantum dots, magnetic nanoparticles and self-assembled monolayers (SAMs). Computational analysis demonstrates and predicts the thermodynamic stability of gold nanomolecules and the importance of ligand-ligand interactions that clearly stands out as a determining factor, especially for species with AL ligands such as Au₃₈(S-AL)₂₄.</p
