A‐Site Cationic Variation to Expand the Sacrificial Layer AVO3 Family Dissolving in Water

open access: yesAdvanced Materials Interfaces, EarlyView.
The visual art depicts atoms dissolving in water, symbolizing the etching of Sr1‐xCaxVO3 thin films. This study demonstrates a new family of water‐soluble materials, expanding the lattice parameter range available for epitaxial growth on sacrificial layers.

Hot exciton effect in photoluminescence of monolayer transition metal dichalcogenide

open access: yesNatural Sciences, Volume 3, Issue 1, January 2023., 2023
The hot excitons (green circle) could be scattered into the light cone by absorbing or emitting acoustic phonon. This acoustic phonon assisted photoluminescence accounts for the non‐lorentzian high energy tail in the PL spectrum and the hot exciton effect is signaificant to linear optical properties of transition metal dichalcogenides.

Comment on ‘Quantum principle of relativity’

open access: yesNew Journal of Physics, 2022
Recently Dragan and Ekert (2020 New. J. Phys . 22 033038) presented arguments that probabilistic dynamics inherent in the realm of quantum physics is related to the propagation of superluminal particles.

Lorentz-conformal transformations in the plane

open access: yesExpositiones Mathematicae, 2017
While conformal transformations of the plane preserve Laplace's equation, Lorentz-conformal mappings preserve the wave equation. We discover how simple geometric objects, such as quadrilaterals and pairs of crossing curves, are transformed under nonlinear Lorentz-conformal mappings.

Magnetic Actuation Under DC and AC Fields of Thermoplastic Polyurethane With Strontium Hexaferrite

open access: yesAdvanced Materials Technologies, EarlyView.
Magnetic thermoplastic polyurethane composites with strontium hexaferrite (SrFe12O19) are produced through a solvent‐free melt‐mixing technique. These composites display a magnetomechanical actuation mechanism, being able to deform (bend and twist) through DC and AC magnetic fields, showcasing their potential as a promising material for the fabrication

Relativity and irreversibility

open access: yesDiscrete Dynamics in Nature and Society, 2004
The Lorentz transformation is extended to the decaying states in a relativistic model of interacting fields. The nonlocal action is defined beyond the Hilbert space.

Frequency‐Selective Terahertz Wave Amplification by a Time Boundary in Huygens' Metasurface

open access: yesAdvanced Optical Materials, EarlyView.
In a free‐standing all‐dielectric Huygens' metasurface, ultrafast pulsed laser excitation is used to establish the time boundary for a coherent modulation to the electric and magnetic polarizability in the adiabatic limit. Amplification of THz waves at frequencies that can be continuously tuned have been achieved, showing an effective energy gain up to

Pedigree reconstruction for triploid apple cultivars using single nucleotide polymorphism array data

open access: yesPLANTS, PEOPLE, PLANET, Volume 5, Issue 1, Page 98-111, January 2023., 2023
Many economically, culturally, and historically important apple cultivars are triploids, which have three copies of each chromosome instead of the more typical two copies in diploids. Despite their prevalence and importance, there have been conflicting reports regarding their origin and their ability to beget diploids.

Amphiphilic Zeolitic Imidazolate Framework for Improved CO2 Separation in PIM‐1 Mixed Matrix Membranes

open access: yesAngewandte Chemie, EarlyView.
An improvement in compatibility between filler ZIF‐94 and polymer PIM‐1 in mixed matrix membranes (MMMs) was achieved through ligand exchange with undecylimidazole (umIm). The modified ZIF‐94 (ZIF‐94‐umIm) presents amphiphilic character and high CO2 adsorption (2.34 mmol g−1 at 90 kPa and 0 °C).

Gauge and Lorentz Transformation Placed on the Same Foundation

open access: yesAdvances in Mathematical Physics, 2011
We show that a “dynamical” interaction for arbitrary spin can be constructed in a straightforward way if gauge and Lorentz transformations are placed on the same foundation.
