A Simple Method for Measuring Fine-to-Ultrafine Aerosols Using Bipolar Charge Equilibrium.
Robert T Nishida, Tyler J Johnson, Joshua S Hassim, Brian M Graves, Adam M Boies, Simone Hochgreb
Jan 15, 2020
Low-cost methods for measuring airborne microparticles and nanoparticles (aerosols) have remained elusive despite the increasing concern of health impacts from ambient, urban, and indoor sources. While bipolar ion sources are...
A dynamic charge-charge interaction modulates PP2A
Xinru Wang, Dimitriya H Garvanska, Isha Nasa, Yumi Ueki, Gang Zhang, Arminja N Kettenbach, Wolfgang Peti, Jakob Nilsson, Rebecca Page
Apr 01, 2020
The recruitment of substrates by the ser/thr protein phosphatase 2A (PP2A) is poorly understood, limiting our understanding of PP2A-regulated signaling. Recently, the first PP2A:B56 consensus binding motif, LxxIxE, was...

Kernel charge equilibration
Abstract
State-of-the-art machine learning (ML) interatomic potentials use local representations of atomic environments to ensure linear scaling and size-extensivity. This implies...
Long-lived and disorder-free charge transfer states enable endothermic charge separation in efficient non-fullerene organic solar cells.

Oct 06, 2020
Organic solar cells based on non-fullerene acceptors can show high charge generation yields despite near-zero donor-acceptor energy offsets to drive charge separation and overcome the mutual Coulomb attraction between electron...
Kinetics versus Charge SeparationSeparation
Oxygen-deficient iron oxide thin films, which have recently been shown to be highly active for photoelectrochemical water oxidation, were surface-functionalized with a monolayer of a molecular iridium water oxidation cocatalyst....
Development of a Charge Estimator for Piezoelectric Actuators
Morteza Mohammadzaheri, Mohammadreza Emadi, Mojtaba Ghodsi, Issam Bahadur, Musaab Zarog, Ashraf Saleem
Jan 01, 2020
Charge of a piezoelectric actuator is proportional to its displacement for a wide area of operating. Hence, a charge estimator can estimate displacement for such actuators. However, existing charge estimators take a sizable...

Biomolecular and electrochemical charge detection by a micromechanical electrometer
A micromechanical electrometer is applied to the label-free detection of biomolecular interactions and electrochemical charge sensing. The primary element of the electrometer is a micromechanical variable capacitor to modulate...
Microscopic origins of charge transport in triphenylene systems
Ian R. Thompson, Mary K. Coe, Alison B. Walker, Matteo Ricci, Otello M. Roscioni, Claudio Zannoni
Jun 05, 2018
We study the effects of molecular ordering on charge transport at the mesoscale level in a layer of ≈9000 hexa-octyl-thio-triphenylene discotic mesogens with dimensions of ≈20×20×60nm3. Ordered (columnar) and...

Extensive layer clouds in the global electric circuit
A fair weather electric field has been observed near the Earth’s surface for over two centuries. The field is sustained by charge generation in distant disturbed weather regions, through current flow in the Global Electric...

Screened Coulomb interactions with non-uniform surface charge
The screened Coulomb interaction between a pair of infinite parallel planes with spatially varying surface charge is considered in the limit of small electrical potentials for arbitrary Debye lengths. A simple expression for the...
Modelling charge transport in data DNA using transfer matrices with diagonal terms
There is increasing evidence that DNA can support a considerable degree of charge transport along the strand by hopping of holes from one base to another, and that this charge transport may be relevant to DNA regulation, damage...
Vapour-Deposited Cesium Lead Iodide Perovskites
Eline M Hutter, Rebecca J Sutton, Sanjana Chandrashekar, Mojtaba Abdi-Jalebi, Samuel D Stranks, Henry J Snaith, Tom J Savenije
Nov 01, 2018
Metal halide perovskites such as methylammonium lead iodide (MAPbI3) are highly promising materials for photovoltaics. However, the relationship between the organic nature of the cation and the optoelectronic quality remains...

Review of Richard Kearney and Brian Treanor (eds.), Carnal Hermeneutics, New York
Samuel R. R. Underwood
Jan 04, 2019
Carnal Hermeneutics is a collection of essays published in 2015 in the “Perspectives in Continental Philosophy” series by Fordham University Press. The contributors fall into two categories: established French philosophers...

Positive charge loading at protein termini is due to membrane protein topology, not a translational ramp
In the great majority of genomes, the use of positive charge increases, on average, approaching protein N-termini. Such charged residues slow ribosomes by interacting with the negatively charged exit tunnel. This has been...

The binding energy and dynamics of charge-transfer states in organic photovoltaics with low driving force for charge separation.

Mar 13, 2019
Recent progress in organic photovoltaics (OPVs) has been enabled by optimization of the energetic driving force for charge separation, and thus maximization of open-circuit voltage, using non-fullerene acceptor (NFA) materials....
