On quantum gravity

open access: yes, 2019
The creation of matter by the structure of the basic quantum fields causes an unbalance within the scalars of the flat Higgs field. The result is Newtonian gravity, scalar vectors that act like a push force.

Shaping Magnetic Liquid Metals Into 3D Leakage‐Free, Shape‐Programmable Structures and Electronics

open access: yesAdvanced Electronic Materials, EarlyView.
This research addresses the fluidity‐induced leakage challenge in the 3D patterning of liquid metals (LMs) by utilizing magnetic liquid metals (MLMs). These 3D MLM structures prevent LM leakage, enable shape programmability and reconfigurability, and exhibit self‐healing and enhanced compression resistance.

Dynamics of Fricke–Painlevé VI Surfaces

open access: yesDynamics
The symmetries of a Riemann surface Σ∖{ai} with n punctures ai are encoded in its fundamental group π1(Σ). Further structure may be described through representations (homomorphisms) of π1 over a Lie group G as globalized by the character variety C=Hom(π1,

Multiscale Coupling Between Macroscopic Mechanics and Atomic Assembly (MM–AA) of Soft‐Lattice Halide Perovskites

open access: yesAggregate, EarlyView.
This review clarifies the multiscale coupling mechanisms between macroscopic mechanics (e.g., surface tension, fluid shear, interfacial stress) and atomic assembly, highlighting the importance of mechanical regulation in suppressing solute aggregation and guiding crystal orientation.

From the Fibonacci Icosagrid to E8 (Part I): The Fibonacci Icosagrid, an H3 Quasicrystal

open access: yesCrystals
This paper introduces a new kind of quasicrystal by Fibonacci-spacing a multigrid of a certain symmetry, like H2, H3, T3, etc. Multigrids of a certain symmetry can be used to generate quasicrystals, but multigrid vertices are not a quasicrystal due to ...

Smart Bioinspired Material‐Based Actuators: Current Challenges and Prospects

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
This work gathers, in a review style, an extensive and comprehensive literature overview on the development of autonomous actuators based on synthetic materials, bringing together valuable knowledge from several studies. Furthermore, the article identifies the fundamental principles of actuation mechanisms and defines key parameters to address the size
