Understanding the Role of Hydrogen and Oxygen in Electronic Phase Changes of Nickelates

Advanced Functional Materials, EarlyView.
The reversible exchange of hydrogen and oxygen in solids is key to their electronic and electro‐chemical functionality. A combination of methods is employed to study the interaction of hydrogen with a prototypical quantum material in a non‐destructive and time‐dependent manner.

Measuring the gap between elicited and revealed risk for investors: An empirical study

FINANCIAL PLANNING REVIEW, Volume 5, Issue 4, December 2022., 2022
Abstract Financial advisors use questionnaires and discussions with clients to determine investment goals, elicit risk preference and tolerance and establish a suitable portfolio allocation for different risk categories. Financial institutions assign risk ratings to their financial products.

Tautological systems and free divisors [PDF]

, 2019
We introduce tautological system defined by prehomogenous actions of reductive algebraic groups. If the complement of the open orbit is a linear free divisor satisfying a certain finiteness condition, we show that these systems underly mixed Hodge ...

Synthetic Active Liquid Crystals Powered by Acoustic Waves

Advanced Materials, EarlyView.
A fully synthetic active liquid crystal, energized by an acoustic field, is presented. This system exhibits active nematic behavior, tunable topological defect dynamics, and persistent hydrodynamic vortices at high activity levels. The material maintains stable properties while enabling precise activity control in a wide range.

Modeling and PDC fuzzy control of planar parallel robot

International Journal of Advanced Robotic Systems, 2017
Many works in the literature have studied the kinematical and dynamical issues of parallel robots. But it is still difficult to extend the vast control strategies to parallel mechanisms due to the complexity of the model-based control. This complexity is

Advancement in Colloidal Metasurfaces: Approaches for Scalable Photonic Devices

Advanced Materials Interfaces, EarlyView.
This perspective explores colloidal metasurfaces composed of plasmonic and emitting nanoparticles assembled by laser interference lithography and template‐assisted self‐assembly methods. Precise design strategies achieve directional emission, low‐threshold lasing, and tunable photonic bandgaps.

Algebraic treatment of the Pais-Uhlenbeck oscillator and its PT-variant

, 2019
The algebraic method enables one to study the properties of the spectrum of a quadratic Hamiltonian through the mathematical properties of a matrix representation called regular or adjoint.

Enhancing the Efficiency of Polariton OLEDs in and Beyond the Single‐Excitation Subspace

Advanced Optical Materials, EarlyView.
Organic light‐emitting diodes (OLEDs) are transforming lighting with eco‐friendly manufacturing and flexible applications. However, since 75 % of excited states (triplets) are non‐emissive, recent research has focused on triplet harvesting. This work proposes a predictive polariton‐based model, exploring conditions for OLED enhancement and showing that

The Frequency‐Domain Lattice Boltzmann Method (FreqD‐LBM): A Versatile Tool to Predict the QCM Response Induced by Structured Samples

Advanced Theory and Simulations, EarlyView.
FreqD‐LBM simulates the oscillatory flow at the surface of a QCM‐D resonator in the presence of structured adsorbates. It derives shifts of frequency and bandwidth (equivalent to dissipation) on different overtones. Applications include rough surfaces, adsorbed rigid particles, adsorbed viscoelastic particles, spheres floating freely above the surface,
