The widely used Doyle-Fuller-Newman (DFN) model for lithium-ion batteries is too computationally expensive certain applications, which has motivated the appearance of a plethora simpler models. These models are usually posed in an ad hoc manner, leading to inconsistencies with DFN and multiple formulations same model, Single Particle Model (SPM) being very good example latter. In this work, we ...

Seit 1994 wurden vom BMBF finanzierte DFN-Forschungsprojekte zu Verzeichnisdiensten an der Universität Tübingen durchgeführt. In den ersten dieser Projekte stand der Aufbau und Betrieb eines Emailverzeichnisses für die deutsche Forschung1 im Vordergrund. Zum Aufrechterhalt dieser Dienste kamen in den Folgeprojekten weitere Aufgaben hinzu, wie z.B. der Aufbau des Verzeichnisdienst-Kompetenzzentr...

Abstract PHANGS–JWST mid-infrared (MIR) imaging of nearby spiral galaxies has revealed ubiquitous filaments dust emission in intricate detail. We present a pilot study to systematically map the filament network (DFN) at multiple scales between 25 and 400 pc NGC 628. MIRI images 7.7, 10, 11.3, 21 ? m 628 are used generate maps emission, while PHANGS–HST B -band yields attenuation features. quant...

Sympathetic ophthalmia is a bilateral uveitis that develops after penetrating injury to one eye. This study aimed to identify the inflammatory cellular sub-phenotypes and expression of pertinent inflammatory cytokines/chemokines in sympathetic ophthalmia (SO). Dalen-Fuchs nodules (DFN), granulomas, and non-granulomatous foci of inflammation were micro-dissected from 15 cases. RNA was extracted,...

      Many large oil and gas fields in the most productive world regions happen to be fractured. The exploration and development of these reservoirs is a true challenge for many operators. These difficulties are due to uncertainties in geological fracture properties such as aperture, length, connectivity and intensity distribution. To successfully address these challenges, it is paramount to im...

A Doyle–Fuller–Newman (DFN) model for the charge and discharge of nano-structured lithium iron phosphate (LFP) cathodes is formulated on basis that transport within nanoscale LFP electrode particles much faster than cell discharge, therefore not rate limiting. We present some numerical solutions to show relevant parameter values, a variety C-rates, it possible sharp fronts form intrude into fro...

BACKGROUND Migraine pain relief is reported by more than 50% of patients who receive low dose (3 mg) of sumatriptan. Currently, there is no two-step autoinjector of low-dose sumatriptan available on the market for acute migraine treatment. To fulfill this need, a fully assembled, single-dose, subcutaneous autoinjector (sumatriptan 3 mg; product-code DFN-11) was developed. The device allows for ...

Numerical simulations of microscopic transport processes in porous electrodes lithium-ion batteries demonstrate the presence spatially localized fluctuations physical quantities on microstructure scale. They can influence macroscopic battery characteristics (for example, degradation rates). These cannot be captured a straightforward manner by widely used electrode theory Doyle, Fuller, and Newm...
