How the Carrier Mobility and Seebeck Coefficient of Doped Semiconducting Polymers Are Controlled by Counterion Interactions and Mesoscale Order

Advanced Functional Materials, EarlyView.
Conventional doping of P3HT with F4TCNQ results in poor charge transport. However, when F4TCNQ is exchanged with LiTFSI, the transport characteristics are greatly enhanced. We find the increase in charge transport is directly related to an increase in the mesoscale ordering of P3HT, resulting in longer and better‐connected transport pathways.

Rationally Designed Bilayer Passivation Strategy for High‐Performance Vacuum‐Processed Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
A bilayer “Anchor‐and‐Seal” passivation strategy using EDAI2 and 4MeO‐PEAI effectively mitigates surface defects in vacuum‐processed perovskite films through synergistic hydrogen bonding and Lewis base coordination. This approach optimizes interfacial energy alignment and suppresses non‐radiative recombination, enabling vacuum‐deposited p‐i‐n ...

A Truly Second-Order and Unconditionally Stable Thermal Lattice Boltzmann Method

Applied Sciences, 2017
An unconditionally stable thermal lattice Boltzmann method (USTLBM) is proposed in this paper for simulating incompressible thermal flows. In USTLBM, solutions to the macroscopic governing equations that are recovered from lattice Boltzmann equation (LBE)

Solvent Co‐Intercalation Enabled Ca Storage in MoS2 for Ca‐Ion Batteries

Advanced Functional Materials, EarlyView.
Regulating electrolyte solvation levels enables otherwise non‐intercalatable Ca2+ ions to reversibly co‐intercalate into molybdenum disulfide (MoS2) as ether‐solvated species. The intercalation reversibility is strongly governed by solvent chain length, as demonstrated using diethylene glycol dimethyl ether (G2) and tetraethylene glycol dimethyl ether (

Lattice Boltzmann Method for the Generalized Black-Scholes Equation

Advances in Mathematical Physics, 2023
In this paper, an efficient lattice Boltzmann model for the generalized Black-Scholes equation governing option pricing is proposed. The Black-Scholes equation is firstly equivalently transformed into an initial value problem for a partial differential ...

Optimal preconditioning of lattice Boltzmann methods

Journal of Computational Physics, 2009
A preconditioning technique to accelerate the simulation of steady-state problems using the single-relaxation-time (SRT) lattice Boltzmann (LB) method was first proposed by Guo et al. [Z. Guo, T. Zhao, Y. Shi, Preconditioned lattice-Boltzmann method for steady flows, Phys. Rev. E 70 (2004) 066706-1]. The key idea in this preconditioner is to modify the

Entropic lattice Boltzmann methods: A review

Computers & Fluids, 2023
في أواخر التسعينيات وأوائل عام 2000، كان مفهوم نظرية H المنفصلة ووظائف Lyapunov كوسيلة لضمان استقرار حلال بولتزمان المشابك تحولًا في النموذج في بناء حلالين حركيين منفصلين وفتح الباب أمام مناقشات ووجهات نظر جديدة حول هذه المسألة. اقترح البناء الإنتروبي إعادة تنظيم مشغل تصادم الاسترخاء عن طريق تغيير كل من جاذب التوازن وعملية الاسترخاء من خلال إدخال ...

Exciton Binding Energy of Phosphorescent Emitter Molecules in Organic Light‐Emitting Diodes

Advanced Functional Materials, EarlyView.
Energy level alignment is key to efficient OLED design, yet determining LUMO energies remains challenging. A methodology based on field‐induced dissociation and kinetic Monte Carlo simulations is presented to extract LUMO energies of iridium‐based phosphorescent emitters from their exciton binding energy.

The Lattice Boltzmann equation for modelling arterial flows : review and application

, 2003
The lattice Boltzmann model (LBM) is a relatively new development in computational fluid dynamics. Here we review the technique with particular emphasis on its application to biological systems.
