4D‐Printed Spin Crossover Metamaterials with Giant Programmable Positive or Negative Thermal Expansion

Advanced Materials, EarlyView.
Spin crossover composite filaments are implemented for the rational design of 4D‐printed mechanical metamaterials. The obtained bi‐material structures guided by a theoretical analysis based on analytical calculations and Finite Element Analysis simulations exhibit giant programmable positive or negative deformation with coefficients of thermal ...

Ferromagnetism of Molecular Beam Epitaxy‐grown Ultra‐thin Cr2Ge2Te6 Films Down to the Monolayer Limit on Si Substrates

Advanced Materials, EarlyView.
Uniform monolayer Cr2Ge2Te6 films are achieved on Si substrates by molecular beam epitaxy. Intrinsic ferromagnetism with perpendicular magnetic anisotropy is established in the films by anomalous Hall effect and superconducting quantum interference device measurements, albeit with strong magnetic fluctuations characteristic of its 2D nature.

The influence of the long-lived quantum Hall potential on the characteristics of quantum devices [PDF]

, 2005
Novel hysteretic effects are reported in magneto-transport experiments on lateral quantum devices. The effects are characterized by two vastly different relaxation times (minutes and days).

Hysteretic Behavior of Steel Reinforced Concrete Columns Based on Damage Analysis

Applied Sciences, 2019
With the aim to model the seismic behavior of steel reinforced concrete (SRC) frame columns, in this research, hysteresis and skeleton curves were obtained based on the damage test results of SRC frame columns under low cyclic repeat loading and the ...

Understanding Operando Water Management in Hydroxide‐Exchange‐Membrane Fuel Cells

Advanced Materials Interfaces, EarlyView.
Effective water management is vital for high‐performance hydroxide‐exchange‐membrane fuel cells. Using a custom water‐flux station, this study quantifies how membrane thickness, microporous layers, and operating conditions dictate internal water transport.

Streamflow Hysteresis Analysis Through a Deep‐Dive Budget of the St Venant Equation Momentum Terms

Water Resources Research
Hysteretic conditions, characterized by non‐unique relationships and temporal phasing of flow variables, are common in unsteady open‐channel flows. Hysteresis effects can lead to significant discharge estimation errors when using traditional, unique ...

Evolution of Materials and Device Stacks for HfO2‐Based Ferroelectric Memories

Advanced Materials Interfaces, EarlyView.
This review summarizes engineering strategies for HfO2 based ferroelectric memories with focus on FeCAP and FeFET structures. It describes how dopant design, stress effects, and interface engineering improve the bulk ferroelectric response. It further discusses how channel engineering supports reliable memory characteristics and scalable integration ...

Hysteresis and hierarchies: dynamics of disorder-driven first-order phase transformations

, 1992
We use the zero-temperature random-field Ising model to study hysteretic behavior at first-order phase transitions. Sweeping the external field through zero, the model exhibits hysteresis, the return-point memory effect, and avalanche fluctuations. There

Hysteretic behavior of an ATPase from the archaebacterium, Halobacterium saccharovorum

Journal of Biological Chemistry, 1989
The membrane-bound detergent-activated ATPase from Halobacterium saccharovorum was purified at a physiological salt concentration (4 M NaCl) in the presence of nonionic detergents. The preparation contains putative subunits of 110, 71, 31, 22, and 14 kDa.
