Fast electro-optical switching controlled by light in nematic LC-based cells are considered. Using a two-wave mixing technique involving diffraction and selfdiffraction of light beams on induced phase dynamic grating, we observe fast flashes of light with generation of many diffracted orders at the output. Such flashe…
This thesis concerns the use of muon-spin spectroscopy (muSR) to investigate novel magnetic behaviours in a wide range of materials. Muon sites in each of these materials are determined using density functional theory (DFT), which strongly aides the analysis of the muSR results. Firstly, an investigation of the M_1/3N…

La contaminación por microplásticos y nanoplásticos constituye un problema emergente de salud pública debido a su amplia distribución ambiental, su capacidad de ingresar al organismo humano y sus posibles efectos sobre diferentes sistemas biológicos. El objetivo de este estudio fue sistematizar una experiencia comunit…
Delays in concrete transportation and placement can reduce workability; therefore, a retarding admixture is required to maintain concrete consistency. This study aimed to analyze the effect of adding Sika Plastiment VZ at dosages of 0.15%, 0.20%, and 0.25% on slump, fresh concrete temperature, density, strength ratio,…
The pyrochlore iridate $Pr_2Ir_2O_7$ remains metallic at low temperatures where its family members insulate. Recently, scanning tunneling spectroscopy experiments have revealed an inhomogeneous mixture of Kondo-screened and Kondo-destroyed regions when its surface is produced by cleaving at room temperature while it r…
Understanding the magnetic interactions that promote high TC in topological quantum materials is essential to effectively design materials whose magnetic configuration persists at high temperatures and are thus practical to integrate into commercial spintronic devices. Here we provide evidence of the origin of the hig…
Quantum dots are tunable semiconductor nanocrystals that can be produced at industrial scales. We present the first ab initio calculation of the scattering of dark matter on electrons bound in quantum dots. The momentum-dependence of a quantum dot's electronic response depends on its morphology and on the dark matter…
Cancer therapy is often limited by the systemic toxicity and dose-dependent adverse effects of conventional chemotherapeutic agents such as doxorubicin (DOX). In this study, a folic acid-functionalized molecularly imprinted polymeric complex based on poly(HEMA) crosslinked with ethylene glycol dimethacrylate was synt…
These Mathematica notebooks contain the code used to generate all non-diagrammatic figures in "Dynamical metastability and transient topological magnons in interacting driven-dissipative magnetic systems."
The mutual exclusion of ferroelectricity and metallic conductivity is a long-standing tenet because itinerant electrons screen long-range Coulomb forces that stabilize the bulk polar order. Here, we break this paradigm by heavily doping a non-polar covalent semiconductor of cubic silicon carbide (3C-SiC) with nitrogen…
Colorimetric biosensing devices represent an important class of point-of-care (POC) diagnostics due to their ability to provide visible test outputs, their ease of integration with smartphone-based sensing, and their portability for field testing. In the context of agrifood safety, there is a growing need for portable…
This paper extends a recently proposed Variational Quantum Algorithm framework for nonlinear elasticity to a broader class of constitutive nonlinearities involving rational powers of the stretch. One-dimensional incompressible Ogden and Mooney-Rivlin models are employed as representative examples to demonstrate the pr…
Skyrmions in 2D magnets are promising candidates for nonvolatile, low-power, and high-density spintronic memories. However, their experimental realization at the 2D limit remains challenging, owing to the difficulty in engineering the required chiral magnetic interactions. Here, we report the creation and direct imagi…
Microorganisms remain a major cause of infectious diseases, emphasizing the need for alternative and complementary antimicrobial strategies. In this context, plant-derived materials have attracted increasing attention for their antimicrobial and protective properties. Chitosan, a biocompatible and cationic biopolymer,…
This study compares three reduced-order modeling (ROM) approaches for flow simulations of generalized Newtonian fluids described by the Carreau rheological model. All three methods rely on offline snapshot generation in the rheological parameter space using the full-order model (FOM), followed by a proper orthogonal d…
At weak coupling, finite-momentum superconductivity is typically associated with broken time-reversal or inversion symmetry of the Fermi surface. Here, we show that lattice-scale pair-density-wave order in rhombohedral multilayer graphene can arise from layer/orbital-dependent pairing interactions, band chirality, and…
Spin-orbit torque (SOT) provides an efficient route for manipulating magnetization in spintronic devices, and its accurate quantification is essential. Here, we investigate Co/Gd-based synthetic ferrimagnets using complementary magnetotransport and magneto-optical techniques. We use a Sagnac magneto-optical interferom…
We discuss the problem of assessing the electronic and vibrational dimensionality of a semiconductor nanostructure: How thin and/or wide must a nanostructure be in order to induce electron and phonon confinement? Clarifying the physical justification for common criteria found in the literature, we view the electron co…
Micro- and nanoplastics (MNPs) are emerging atmospheric pollutants, yet the processes controlling their transfer from the ocean to the atmosphere remain poorly constrained. Sea spray aerosol (SSA), produced when bubbles generated by breaking waves burst at the ocean surface, provides a plausible pathway for transferri…
