Magnetic Bistability for a Wider Bandwidth in Vibro-Impact Triboelectric Energy Harvesters [PDF]

Micromachines, 2023
Mechanical energy from vibrations is widespread in the ambient environment. It may be harvested efficiently using triboelectric generators. Nevertheless, a harvester’s effectiveness is restricted because of the limited bandwidth.

Covalent Organic Frameworks: A 2D Platform for Controlled Nanostructuring of Single Ion Magnets [PDF]

Structural Dynamics
Bulk magnetic materials play a crucial role in everyday life. Single molecule magnets (SMMs) and single ion magnets (SIMs), collectively known as molecular magnets (MMs), exhibit magnetic bistability and slow magnetization relaxation.

Magnetic Field Induced Orientational Bistability in a Ferronematic Cell [PDF]

Molecular Crystals and Liquid Crystals, 2002
The equilibrium states of a suspension of single-domain ferroparticles in a nematic liquid-crystalline homeotropic cell subject to an external magnetic field are studied. We predict the existence of magnetic field induced orientational bistability in such a system in a magnetic field ?102 Oe.

Enhanced Optical Bistability of a Metasurface Based on Asymmetrically Optimized Mirror-Induced Magnetic Anapole States

Applied Sciences
In the field of modern optical computing and communication, optical bistability plays a crucial role. With a weak third-order nonlinear coefficient, low switch thresholds of optical bistability from Si-based nanophotonic structures remain a challenge. In

Unstable slow oscillations couple with epileptogenic fast‐rhythm bistability in sleep‐related epilepsy: A stereoelectroencephalographic study [PDF]

Epilepsia, Volume 67, Issue 6, Page 2924-2939, June 2026.
We examined the functional relationship between large‐scale δ‐band phase synchrony and local epileptogenic β–γ‐band amplitude bistability during NREM sleep. Increased synchrony and strong bistability characterized the epileptogenic zone, with strongest effects during N2 sleep, when seizures most frequently occur.

Spin Crossover and Magnetic-Dielectric Bistability Induced by Hidden Pseudo-Jahn–Teller Effect

Magnetochemistry, 2020
In a semi-review paper, we show that the hidden Jahn–Teller effect (JTE) and pseudo-JTE (PJTE) in molecular systems and solids, under certain conditions lead to the formation of two coexisting stable space configurations with different magnetic and ...

Cethrene’s Catch-22: Is Trading Magnetism for Bistability Inevitable? [PDF]

Organic Letters
Cethrenes represent a promising platform for realizing all-organic magnetic photoswitches─provided that three requirements are met. The open form needs a thermally accessible triplet state to unlock magnetic properties, its energy relative to the closed form should lie within an accessible range, and the energy barrier between the two forms must be ...
