First person – Arijita Ghosh
No full textABSTRACT
First Person is a series of interviews with the first authors of a selection of papers published in Journal of Cell Science, helping early-career researchers promote themselves alongside their papers. Arijita Ghosh is the first author on “Leucine-rich repeat-containing 8B protein is associated with the endoplasmic reticulum Ca2+ leak in HEK293 cells”, published in Journal of Cell Science. Arijita is a PhD student in the laboratory of Amal Kanti Bera at the Indian Institute of Technology Madras, Chennai, India, investigating the role of leucine-rich repeat-containing 8 proteins in cellular calcium homeostasis.</jats:p

Beyond national literatures: Empire and Amitav Ghosh
No full textScholarship on the writer Amitav Ghosh has addressed issues of nationalism, postcolonial identity, ecocriticism, testimony, subalternity, and historiography. But the idea of Ghosh as an Asian American author with a particular relationship to the United States and its national mythologies, has barely been considered. In this essay, I explore this neglected aspect of Ghosh’s œuvre by looking at the idea of America in his writing and by situating his work within what I term "the Bengali American grain". Reading his work alongside that of other Bengali American writers and arguing that it is more ambitious thematically and more anti-imperialistic, I probe Ghosh’s problematic relationship with the United States, asking how his hemispheric writing continues to extend and even alter the terrain often associated with Asian American literature
Electronic Structure of Cobalt-Corrole-Pyridine Complexes:Noninnocent Five-Coordinate Co(II) Corrole-Radical States
No full textTwo sets of complexes of Co-triarylcorrole-bispyridine complexes, Co[TpXPC](py)2 and Co[Br8TpXPC](py)2 have been synthesized, where TpXPC refers to a meso-tris(para-X-phenyl)corrole ligand with X = CF3, H, Me, and OMe and Br8TpXPC to the corresponding β-octabrominated ligand. The axial pyridines in these complexes were found to be labile and, in dilute solutions in dichloromethane, the complexes dissociate almost completely to the five-coordinate monopyridine complexes. Upon addition of a small quantity of pyridine, the complexes revert back to the six-coordinate forms. These transformations are accompanied by dramatic changes in color and optical spectra. 1H NMR spectroscopy and X-ray crystallography have confirmed that the bispyridine complexes are authentic low-spin Co(III) species. Strong substituent effects on the Soret maxima and broken-symmetry DFT calculations, however, indicate a CoII-corrole2- formulation for the five-coordinate Co[TpXPC](py) series. The calculations implicate a Co(dz2)-corrole("a2u") orbital interaction as responsible for the metal-ligand antiferromagnetic coupling that leads to the open-shell singlet ground state of these species. Furthermore, the calculations predict two low-energy S = 1 intermediate-spin Co(III) states, a scenario that we have been able to experimentally corroborate with temperature-dependent EPR studies. Our findings add to the growing body of evidence for noninnocent electronic structures among first-row transition metal corrole derivatives.</p
Electronic Structure of Manganese Corroles Revisited: X‑ray Structures, Optical and X‑ray Absorption Spectroscopies, and Electrochemistry as Probes of Ligand Noninnocence
No full textPresented
herein is a detailed multitechnique investigation of ligand noninnocence
in S = 3/2 manganese corrole
derivatives at the formal MnIV oxidation state. The Soret
maxima of Mn[TpXPC]Cl (TpXPC = meso-tris(p-X-phenyl)corrole, where X =
CF3, H, Me, and OMe) were found to red-shift over a range
of 37 nm with increasing electron-donating character of X. For Mn[TpXPC]Ph, in contrast, the complex Soret envelopes were found
to be largely independent of X. These observations suggested a noninnocent
corrole•2–-like ligand for the MnCl complexes
and an innocent corrole3– ligand for the MnPh complexes.
Single-crystal X-ray structures of three Mn[TpXPC]Cl
complexes revealed skeletal bond-length alternations indicative of
a noninnocent corrole, while no such alternation was observed for
Mn[TpOMePC]Ph. B3LYP density functional theory (DFT)
calculations on Mn[TPC]Cl yielded strong spatial separation of the
α and β spin densities, consistent with an antiferromagnetically
coupled MnIII-corrole•2– description.
By comparison, relatively little spatial separation of the α
and β spin densities was found for Mn[TPC]Ph, consistent with
an essentially MnIV-corrole3– description.
X-ray absorption of near-edge spectroscopy (XANES) revealed a moderate
blue shift of 0.6 eV for the Mn K-pre-edge of Mn[TpCF3PC]Ph and a striking enhancement of the pre-edge intensity,
relative to Mn[TpCF3PC]Cl, consistent
with a more oxidized, i.e., MnIV, center in Mn[TpCF3PC]Ph. Time-dependent DFT calculations indicated
that the enhanced intensity of the Mn K-pre-edge of Mn[TpCF3PC]Ph results from the extra 3dz2 hole, which mixes strongly with the Mn 4pz orbital. Combined with similar results on
Fe[TPC]Cl and Fe[TPC]Ph, the present study underscores the considerable
potential of metal K-edge XANES in probing ligand noninnocence in
first-row transition-metal corroles. Cyclic voltammetry measurements
revealed highly negative first reduction potentials for the Mn[TpXPC]Ph series (∼−0.95 V) as well as large
electrochemical HOMO-LUMO gaps of ∼1.7 V. The first reductions,
however, are irreversible, suggesting cleavage of the Mn–Ph
bond

Ep. #040 - Amitav Ghosh
No full textThis recording and transcript form part of a collection of podcasts conducted by the Cultures of Energy at Rice University. Cultures of Energy brings writers, artists and scholars together to talk, think and feel their way into the Anthropocene. We cover serious issues like climate change, species extinction and energy transition. But we also try to confront seemingly huge and insurmountable problems with insight, creativity and laughter.Cymene and Dominic define (finally!) professionalism and offer a brief review of Leonardo DiCaprio’s soon to be released climate change documentary, Before the Flood. Then (11:43) we are very pleased to welcome to the podcast acclaimed novelist, Amitav Ghosh, author of The Shadow Lines (1988), The Hungry Tide (2004) and The Ibis trilogy (2008-2015), among many other works. We talk about his latest work of non-fiction, The Great Derangement: Climate Change and the Unthinkable (University of Chicago Press, 2016) and why he thinks it has proven so difficult to bring climate change into literature. We discuss the worldview of the novel and how its emphasis on creating believable narratives has excluded precisely the kinds of unlikely anthropocenic encounters that are becoming increasingly frequent across the world. Amitav argues that before an alternate world can become a reality, it needs to become an imaginative reality and this is why the arts are so crucial to coming to terms with the Anthropocene. We also discuss “serious” art’s fear of being deemed merely “illustrative” and how this may be linked to a Cold War aversion to the aesthetics of socialist realism. Now, Amitav warns, the world has risen up as a protagonist even as our means of representation aren’t up to engaging it. He predicts that the mansions of serious fiction will suffer a similar fate to the mansions of Miami beach as our waters rise. We talk about what is really being denied in climate change denial and how the privileges and comforts of a carbon-fueled lifestyle is something which neither the West nor Asia is prepared to give up. We close with Amitav’s own next novel project and how climate change inspires him personally and artistically
