Look, a ToSsphere! : Behind the checkbox of Terms of Service
- 2023
-
Artistic workabstract
- In this project, I attempt to go behind the checkbox and unpack what is it that we agree on when we check ‘I have read and agree on ToS’ boxes. By engaging with ToS at different scales – zooming in and out – through reading, translating, and transposing, I explore what each mode of engagement reveals, what questions they lead to, and how these explorations could inform designers.

Correlated electron behavior of metalorganic molecules: insights from density functional theory and exact diagonalization studies.
-
Other publication (other academic/artistic)abstract
- The proper description of electronic structure of correlated orbitals in the metal centers of functional metalorganics is a challenging problem. In this letter, we apply density functional theory and exact diagonalization method in a many body approach to study the ground state electronic conguration of iron porphyrin (FeP) molecule. Our study reveals that FeP is a potential candidate for realizing a spin crossover due to a subtle balance of crystal elds and hybridization of the Fe d-orbitals and ligand N p-states. Moreover, the mechanism of switching between two close lying electronic congurations of Fe-d orbitals is revealed. This hybrid method can generally be applied to properly describe the electronic and related low energy physics of the whole class of correlated metal centered organometallic molecules.

Controlling electronic structure and transport properties of zigzag graphene nanoribbons by mono- and difluorinated edge functionalization
-
Other publication (other academic/artistic)abstract
- In this work, we report a detailed study of the electronic structure and transport properties of mono- and di-fluorinated edges of zigzag graphene nanoribbons (ZGNR) using density functional theory (DFT). The calculated formation energies at 0K indicate that the stability of the nanoribbons increases with the increase in the concentration of di-fluorinated edge C atoms along with an interesting variation of the energy gaps between 0.0 to 0.66 eV depending on the concentration. This gives a possibility of tuning the band gaps by controlling the concentration of F for terminating the edges of the nanoribbons. The DFT results have been reproduced by single band tight binding as well as density functional tight binding methods. Using non-equilibrium Green functional method, we have calculated the transmission coecients of several mono and di-fluorinated ZGNR as a function of unit cell size and degree of homogeneous disorder caused by the random placement of mono and di-fuorinated C atoms at the edges.

Attention effects on vicarious modulation of nociception and pain

- The observation of others' facial expressions of pain has been shown to facilitate the observer's nociceptive responses and to increase pain perception. We investigated how this vicarious facilitation effect is modulated by directing the observer's attention toward the meaning of pain expression or the facial movements. In separate trials, participants were instructed to assess the "intensity of the pain expression"(meaning) or to "discriminate the facial movements" in the upper vs lower part of the face shown in 1-second dynamic clips displaying mild, moderate, or strong pain expressions or a neutral control. In 50% of the trials, participants received a painful electrical stimulation to the sural nerve immediately after the presentation of the expression. Low-level nociceptive reactivity was measured with the RIII-response, and pain perception was assessed using pain ratings. Pain induced by the electrical stimulation increased after viewing stronger pain expressions in both tasks, but the RIII-response showed this vicarious facilitation effect only in the movement discrimination task at the strongest expression intensity. These findings are consistent with the notion that vicarious processes facilitate self-pain and may prime automatic nociceptive responses. However, this priming effect is influenced by top-down attentional processes. These results provide another case of dissociation between reflexive and perceptual processes, consistent with the involvement of partly separate brain networks in the regulation of cortical and lower-level nociceptive responses. Combined with previous results, these findings suggest that vicarious pain facilitation is an automatic process that may be diminished by top-down attentional processes directed at the meaning of the expression.

Depth distribution of alkali metal ions on supported graphene in the presence of water

Journal article (peer-reviewed)abstract
- The interaction of alkali ions with multilayer graphene is critical in many applications, for example in energy storage devices. This requires a detailed understanding of ion interactions with carbonaceous layers. The mechanism of ion intercalation into graphene can be different from that observed for hard graphite. In this paper, we present an investigation of the vertical alkali ion (Na, K, Cs) distribution on multilayer graphene deposited onto SiO2 in vacuum and in the presence of water vapor using Standing Wave Ambient Pressure Photoemission Spectroscopy. It was found that Cs, K, and Na ions do not intercalate into multilayer graphene under vacuum conditions. The most likely reasons for this behavior are the reversibility of the process due to large inter-sheet spacing or lack of time for intercalation. When exposed to water vapor, Na ions intercalate soft carbon whereas Cs ions do not. This is a clear indication for the difference in the intercalation mechanisms on hard graphite and soft graphene.
