Disentanglement–Induced Bistability in a Magnetic Resonator

Advanced Quantum Technologies
Abstract Multi–stability in the response of a ferrimagnetic spin resonator to an externally applied driving is experimentally studied. The observed multi–stability cannot be derived from any master equation that linearly depends on the spins' reduced density operator.

Stimuli‐Responsive Hydrogels for Optical Applications: Mechanisms, Architectures, and Translational Challenges

Aggregate, Volume 7, Issue 6, June 2026.
The review discusses stimuli‐responsive hydrogels as soft optical materials that translate physical, chemical, and biological cues into refractive‐index, scattering, birefringence, diffraction, and transparency changes. It examines major stimulus classes and photonic architectures for biosensing, waveguiding, adaptive lenses, smart windows, and therapy.

Sleep‐like slow waves during resting‐state: A promising EEG biomarker of amyloid and neurodegeneration in preclinical Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION Growing evidence supports a critical role of sleep slow waves (SW) in Alzheimer's disease (AD). However, wake SW (sleep‐like SW potentially reflecting local intrusions of sleep) remain unexplored in AD. METHODS A total of 274 older adults with subjective cognitive decline (SCD) (INSIGHT‐preAD cohort, 76.6 ± 3.5 years) underwent (i)

Chemisorption of lanthanide single-molecule magnets on surfaces

Fundamental Research
Lanthanide single-molecule magnets (SMMs) have gained more attention compared to transition metal SMMs since the discovery of the seminal terbium(III) bis-phthalocyaninato SMM [TbPc2] in 2003.

Controlling of the single domain wall propagation in magnetic microwires by magnetostatic interaction

Journal of Science: Advanced Materials and Devices
Ultrafast magnetization switching through the single domain wall (DW) propagation has been reported in amorphous micrometric and submicrometric wires. However the performance of prospective devices utilizing DW propagation is determined by the degree to ...

Reversible I2 Uptake Induces Record‐High Spin‐Crossover Hysteresis in a Fe(II) Hofmann‐Type MOF

Chemistry – A European Journal, Volume 32, Issue 21, 1 June 2026.
Reversible iodine uptake in a flexible Fe(II) Hofmann‐type MOF [Fe(pz)Pd(CN)4] induces record‐wide SCO hysteresis. Gas‐phase I2 acts as internal chemical pressure, stabilizing both high‐spin and LS states without altering the framework, providing a general strategy for tunable bistability in coordination networks.

Soft Ferroelectrics in One Dimension: Ferroelectric Columnar Liquid Crystals

ChemPlusChem, Volume 91, Issue 6, June 2026.
Helical ferroelectric columnar liquid crystals (FCLCs) confine bistable axial polarization within individual columns. An electric field reversibly flips the macrodipole, enabling two nonvolatile states readable as “0” and “1.” This Cconcept highlights supramolecular locking and helical architectures that deliver genuine switching and long‐lived zero ...

Design of Two‐Segment Constant‐Force Compliant Mechanisms via Stiffness‐Matched Parallel Integration

Engineering Reports, Volume 8, Issue 6, June 2026.
This work presents a novel design for two‐segment constant‐force compliant mechanisms that achieve dual‐stage zero‐stiffness via stiffness‐matched parallel integration. Experimental results demonstrate constant forces of 4 N and 20 N with less than 5% variation, enabling extended operational ranges for precision applications such as robotic ...
