Evaluation of Force Fields for Molecular Dynamics Simulations of Platinum in Bulk and Nanoparticle Forms [PDF]
J. Chem. Theory Comput. 2021, 17, 7, 4486-4498, 2021 Understanding the size- and shape-dependent properties of platinum nanoparticles is critical for enabling the design of nanoparticle-based applications with optimal and potentially tunable functionality. Toward this goal, we evaluated nine different empirical potentials with the purpose of accurately modeling faceted platinum nanoparticles using ...

Local charge transfer doping in suspended graphene nanojunctions [PDF]
APL 100, 023306 (2012), 2012 We report electronic transport measurements in nanoscale graphene transistors with gold and platinum electrodes whose channel lengths are shorter than 100 nm, and compare them with transistors with channel lengths from 1 \textmu{}m to 50 \textmu{}m. We find a large positive gate voltage shift in charge neutrality point (NP) for transistors made with ...

An attention-based deep learning network for predicting Platinum resistance in ovarian cancer [PDF]
arXiv, 2023 Background: Ovarian cancer is among the three most frequent gynecologic cancers globally. High-grade serous ovarian cancer (HGSOC) is the most common and aggressive histological type. Guided treatment for HGSOC typically involves platinum-based combination chemotherapy, necessitating an assessment of whether the patient is platinum-resistant.

Proximity-induced superconductivity in platinum metals [PDF]
Phys. Rev. B 68, 132502 (2003), 2003 The diamagnetism of platinum metals (N: Rh, Pt, Pd), which is induced by the proximity effect of a superconductor (S: Nb), has been investigated for N-S double layers. Notwithstanding the strong spin fluctuation in platinum metals, the screening distance \rho in N increases with a decrease in temperature and reaches a value which is expected in ...

Ultrafast electron dynamics in platinum and gold thin films driven by optical and terahertz fields [PDF]
, 2021 We investigate the ultrafast electron dynamics triggered by terahertz and optical pulses in thin platinum and gold films by probing their transient optical reflectivity. The response of the platinum film to an intense terahertz pulse is similar to the optically-induced dynamics of both films and can be described by a two-temperature model. Surprisingly,
