Electronic symmetry breaking by charge disproportionation results in multifaceted changes in the electronic, magnetic and optical properties of a material, triggering ferroelectricity, metal/insulator transition and colossal magnetoresistance. Yet, charge disproportionation lacks technological relevance because it occurs only under specific physical conditions of high or low temperature or high pressure. Here we demonstrate a voltage-triggered charge disproportionation in thin molecular films of a metal-organic complex occurring in ambient conditions. This provides a technologically relevant molecular route for simultaneous realization of a ternary memristor and a binary memcapacitor, scalable down to a device area of 60 nm. Supported by mathematical modelling, our results establish that multiple memristive states can be functionally non-volatile, yet discrete-a combination perceived as theoretically prohibited. Our device could be used as a binary or ternary memristor, a binary memcapacitor or both concomitantly, and unlike the existing 'continuous state' memristors, its discrete states are optimal for high-density, ultra-low-energy digital computing.
Localized atomistic disorder in halide-based solid electrolytes (SEs) can be leveraged to boost Li mobility. In this study, Li transport in structurally modified LiHoCl, via Br introduction and Li deficiency, is explored. The optimized Li Ho Cl Br achieves an ionic conductivity of 3.
SiGe alloy nanocrystals (NCs) are a class of benign semiconductors that show size and composition-tunable energy gaps and promising optical properties because of the lattice disorder. The random distribution of elements within the alloys can lead to efficient light-matter interactions, making them attractive for Si-compatible optoelectronic devices, transistors, charge storage, and memory applications. However, the fabrication of discrete, quantum-confined alloys has proved a challenging task.
US courts regularly assess fines, fees, and costs against criminal defendants. Court-related debt can cause continuing court involvement and incarceration, not because of new crimes, but because of unpaid financial obligations. We conducted an experiment with 606 people found guilty of misdemeanors in Oklahoma County, Oklahoma.
Gliadin nanoparticle (GNP) is a promising foaming agent, but its application is hindered by the limited foam stability under low acidic conditions. Herein, we attempted to tune the foam stability of GNP by coating it with flaxseed gum (FG) and investigated the structure, interfacial behaviors, and foam functionality of gliadin-FG (GFG) particles at pH 4.5.
- This study analyzes data from the Nationwide Emergency Department Sample to understand characteristics and costs associated with emergency department visits for facial lacerations from 2019.
- Findings reveal over 2.5 million ED visits, primarily unintentional injuries, with scalps being the most common injury site, predominantly affecting adult males who often have private insurance.
- Most encounters occurred during summer months (June-August) in large urban areas and at teaching hospitals, highlighting the demographic and economic factors involved in facial laceration treatment in the U.S. emergency departments.
