Soliton ratchets [PDF]

, 2001
The mechanism underlying the soliton ratchet, both in absence and in presence of noise, is investigated. We show the existence of an asymmetric internal mode on the soliton profile which couples, trough the damping in the system, to the soliton ...

Electro‐Chemo‐Mechanical Coupling in Hf0.5Zr0.5O2 Ferroionic Heterostructures

Advanced Functional Materials, Volume 36, Issue 37, 7 May 2026.
Schematic of a ferroionic HZO heterostructure where epitaxial interfaces enable dynamic oxygen‐vacancy exchange, coupling ionic and ferroelectric degrees of freedom. Vacancy‐mediated polarization modulation biases HZO polymorphism, suppresses leakage, and enhances piezoelectric response, yielding distinct butterfly‐loop evolution and diode‐like ...

Effect of ions added by mordant and brightener on the signal structure and energy storage properties of natural dye-based DSSCs

Journal of Chemical Research
It has been observed experimentally that the output voltage profiles are exponential of two types: rising or decaying; the structure of these profiles is controlled by the mobility of charges: ions and electrons. A comparison between the arrival times of

Canonical interacting quantum fields on two-dimensional de Sitter space

Physics Letters B, 2017
We present the P(φ)2 model on de Sitter space in the canonical formulation. We discuss the role of the Noether theorem and we provide explicit expressions for the energy-stress tensor of the interacting model.

Visual Behavior in Inline Speed Skating: An Eye‐Tracking Evaluation for Performance Analysis

European Journal of Sport Science, Volume 26, Issue 5, May 2026.
ABSTRACT This study analyzed oculomotor behavior (fixations and saccades) in 19 competitive inline speed skaters (5 males, 14 females; aged 10–26 years) from the Aragonese Skating Federation (Spain), comparing high‐performance (N1) and intermediate (N2) groups. Participants completed optometric assessments and eye‐tracking during 200 m time trials on a

Viscoelasticity and Stokes-Einstein relation in repulsive and attractive colloidal glasses

, 2007
We report a numerical investigation of the visco-elastic behavior in models for steric repulsive and short-range attractive colloidal suspensions, along different paths in the attraction-strength vs packing fraction plane. More specifically, we study the

Different Routes for Camellia Sinensis–Mediated Synthesis of Iron Oxide Nanoparticles: Structural, Thermal, and Magnetic Properties

ChemistrySelect, Volume 11, Issue 19, 20 May 2026.
Different green‐assisted routes (After Synthesis—ASR; Green Subsequent—SSR; Green in situ—ISSR) using Camellia sinensis to produce functionalized iron‐based oxide nanoparticles with controlled and distinct structural and magnetic properties. ABSTRACT Green‐assisted iron oxide nanoparticles (NPs) were synthesized using Camellia sinensis extract (green ...

Hole Polaronic Confinement in (111) Yttria‐Stabilised Zirconia

Small, Volume 22, Issue 25, 4 May 2026.
Ultrathin epitaxial YSZ(111) films unexpectedly develop p‐type mixed conduction and amplified electromechanical coupling under oxidizing conditions. Combined transport measurements and first‐principles modeling reveal that nanoscale confinement and ordered dopant–vacancy complexes stabilize localized O 2p hole polarons at the surface. A canonical ionic
