A Lagrangian Approach for Calculating Microsphere Deposition in a One-Dimensional Lung-Airway Model

JOURNAL OF BIOMECHANICAL ENGINEERING-TRANSACTIONS OF THE ASME, 137(9).

By: M. Vaish n & C. Kleinstreuer n

author keywords: lung-equivalent trumpet model; OPENFOAM solver; radial force function; microsphere transport; total lung deposition
MeSH headings : Air; Humans; Lung / metabolism; Microspheres; Models, Biological
TL;DR: Using the open-source software openfoam as the solver, a novel approach to calculate microsphere transport and deposition in a 1D human lung-equivalent trumpet model (TM) is presented and a new radial force has been developed which generates particle trajectories toward the wall.

Tuning Open-Circuit Voltage in Organic Solar Cells with Molecular Orientation

ACS APPLIED MATERIALS & INTERFACES, 7(24), 13208–13216.

By: B. Kitchen n, O. Awartani n, R. Kline*, T. McAfee n, H. Ade n  & . Brendan T. O'Connor  n

author keywords: solar cells; organic electronics; open-circuit voltage; molecular orientation
TL;DR: The results suggest that, in the BHJ OPV cell, the hole energy level in the charge transfer state is defined in part by the orientation distribution of the P3HT at the interface with PCBM, which is comparable to an archetypal bulk heterojunction (BHJ) device. (via Semantic Scholar)
