Abstract:
<abstract><p>This study investigated how permanent charges influence the dynamics of ionic channels. Using a quasi-one-dimensional classical Poisson–Nernst–Planck (PNP) model, we investigated the behavior of two distinct ion species—one positively charged and the other negatively charged. The spatial distribution of permanent charges was characterized by zero values at the channel ends and a constant charge $ Q_0 $ within the central region. By treating the classical PNP model as a boundary value problem (BVP) for a singularly perturbed system, the singular orbit of the BVP depende

AbstractIn this work, we consider ionic flow through ion channels for an ionic mixture of a cation species (positively charged ions) and an anion species (negatively charged ions), and examine effects of a positive permanent charge on fluxes of the cation species and the anion species. For an ion species, and for any given boundary conditions and channel geometry,we introduce a ratio _(Q) = J(Q)/J(0) between the flux J(Q) of the ion species associated with a permanent charge Q and the flux J(0) associated with zero permanent charge. The flux ratio _(Q) is a suitable quantity for measuring an e

Electret filter composed of permanently charged electret fibers is a good material for environmental protection. A novel kind of electret melt-blown nonwovens (EMNs) doped with nano-tourmaline was developed by corona charging in this paper. The structure of web, mechanical properties, surface charge density and filtration efficiency of samples were discussed. The results showed that the structure of EMNs became loose and the initial surface charge density was increased markedly. Furthermore, the EMNs exhibited higher filtration efficiency and lower pressure drop, especially the content of nano

In this work, the dependence of reversal potentials and zero-current fluxes on diffusion coefficients are examined for ionic flows through membrane channels. The study is conducted for the setup of a simple structure defined by the profile of permanent charges with two mobile ion species, one positively charged (cation) and one negatively charged (anion). Numerical observations are obtained from analytical results established using geometric singular perturbation analysis of classical Poisson–Nernst–Planck models.

Two different degradation mechanisms of the devices under negative bias stress (NBS) are identified. At low V G,s for a short t s, NiO bulk traps trapping/de-trapping electrons are responsible for decrease/recovery of the leakage current, respectively. At higher V G,s or long t s, the device transfer characteristic curves and threshold voltage (V TH) are almost permanently neg

Abstract In an isothermal liquid, only the Coulomb force which is the force acting on the free charges, can contribute to permanent electrohydrodynamic motion. In the absence of a direct charge injection, pumping can be achieved due to the charges associated with the heterocharge layers of finite thickness in the vicinity of the electrodes which are based on the process of dissociation of a neutral electrolytic species and recombination of the generated ions. This type of pumping is referred to as pure conduction pumping. The conduction pumping mechanism is experimentally investigated here wit

The capacitor dielectric is the silicon oxide gate insulation. Smaller devices have less capacitance and require less charge per volt and are therefore mo

Abstract:
The predominant class of molecular systems considered so-far towards applications in the realm of quadratic nonlinear optics has been derived from the all-pervading "molecular diode" template as exemplified by paranitroaniline-like molecules. The underlying basic paradigm consists in the dipolar anchoring of an interacting couple of electron donor and acceptor groups to a conjugated π electron linkage(1). The virtue of such a configuration is to provide a significant electronic charge displacement in the ground state which is further enhanced upon directional optical excitation towards the cha

Abstract:
Harmful algal blooms (HABs) threaten recreational waters and public supplies across the US, causing detrimental economic and environmental effects to communities. HABs can be mitigated with dissolved air flotation (DAF) treatment, which requires addition of pH-sensitive charged chemicals to neutralize algae, allowing them to attach to microbubbles and float to the surface. During HAB events and photosynthesis, algae raise the pH to levels that are not ideal for DAF. Traditionally, pH is reduced with a strong acid; however, this adds operational cost and permanently adjusts the water’s pH. This

Abstract:
We examine the interplay between monetary policy, bank risk-taking, and financial stability in a quantitative macroeconomic model with endogenous risk-taking by banks and systemic crises. Banks’ access to leverage depends on their charter value, which is itself affected by movements in the real interest rate. We find that permanent shifts in the long-term real interest rate have a significant impact on banks’ leverage and on their investments in systemically risky assets, while transitory movements have a more limited impact. We show that in the presence of systemic risk-taking, the systemic c

Abstract:
Under the United Nations Charter, the U.N. Security Council has several important functions and powers, not least with regard to taking binding actions to maintain international peace and security. The ten elected members have the opportunity to influence this area and others during their two-year terms on the Council. In this paper, we aim to illustrate some of these opportunities, identify potential guidance from prior elected members’ experiences, and outline the key procedures that incoming elected members should be aware of as they prepare to join the Council. In doing so, we seek in part
