Article Abstract

Density functional theorymolecular dynamics simulations were employed to give insights into the mechanism of voltage generation based on a water-filled single-walled boron-nitrogen nanotube (SWBNNT). Our calculations showed that (1) the transport properties of confined water in a SWBNNT are different from those of bulk water in view of configuration, the diffusion coefficient, the dipole orientation, and the density distribution, and (2) a voltage difference of several millivolts would generate between the two ends of a SWBNNT due to interactions between the water dipole chains and charge carriers in the tube. Therefore, this structure of a water-filled SWBNNT can be a promising candidate for a synthetic nanoscale power cell as well as a practical nanopower harvesting device.

Amphetamines are psychostimulants that are commonly used to treat neuropsychiatric disorders and are prone to misuse. The pathogenesis of amphetamine use disorder (AUD) is associated with dysbiosis (an imbalance in the body's microbiome) and bacterially produced short-chain fatty acids (SCFAs), which are implicated in the gut-brain axis. Amphetamine exposure in both rats and humans increases the amount of intestinal , which releases SFCAs.

This research explores the dynamical properties and solutions of actin filaments, which serve as electrical conduits for ion transport along their lengths. Utilizing the Lie symmetry approach, we identify symmetry reductions that simplify the governing equation by lowering its dimensionality. This process leads to the formulation of a second-order differential equation, which, upon applying a Galilean transformation, is further converted into a system of first-order differential equations.

Unveiling additive effects on molecular packing and charge transfer in organic solar cells: an AIMD and DFT study.

Additive assisted strategies play a crucial role in optimizing the morphology and improving the performance of organic solar cells (OSCs), yet the molecular-level mechanisms remain unclear. Here, we employ molecular dynamics (AIMD) and density functional theory (DFT) to elucidate the influence of typical additives of 1,8-diiodooctane (DIO) and 3,5-dichlorobromobenzene (DCBB) on molecular packing, electronic structures, and charge transport. It can be observed that both additives can enhance the stacking properties of the donor and acceptor materials, yet they have different effects on the local electrostatic environment.

Excitatory glycine receptors control ventral hippocampus synaptic plasticity and anxiety-related behaviors.

Excitatory glycine receptors (eGlyRs), composed of the glycine-binding NMDA receptor subunits GluN1 and GluN3A, have recently emerged as a novel neuronal signaling modality that challenges the traditional view of glycine as an inhibitory neurotransmitter. Unlike conventional GluN1/GluN2 NMDARs, the distribution and role of eGlyRs remain poorly understood. Here, we show that eGlyRs are highly enriched in the ventral hippocampus (VH) and confer distinct properties on this brain region.

Proto-SLIPS: Slippery Liquid-Infused Surfaces that Release Highly Water-Soluble Agents.

ACS Appl Mater Interfaces

Department of Chemistry, University of Wisconsin-Madison, 1101 University Ave., Madison, Wisconsin 53706, United States.

Slippery liquid-infused porous surfaces (or "SLIPS") can prevent bacterial surface fouling, but they do not inherently possess the means to kill bacteria or reduce cell loads in surrounding media. Past reports show that the infused liquids in these materials can be leveraged to load and release antimicrobial agents, but these approaches are generally limited to the use of hydrophobic agents that are soluble in the infused oily phases. Here, we report the design of so-called "proto-SLIPS" that address this limitation and permit the release of highly water-soluble (or oil-insoluble) agents.
