abstract = {In this report, a first-principles investigation of the Fe<inf>3</inf>O<inf>4</inf> (001) surface using Density Functional Theory (DFT) with Hubbard U and inter-site V corrections (DFT + U + V) is presented. By considering the DFT and DFT + U approaches, a semi-metallic nature is observed, while by applying the DFT + U + V method, a pronounced gap is created at the Fermi level, in agreement with the insulating nature of the surface. Furthermore, Cu$^textrm2+$ adsorption simulations were performed, revealing that the incorporation of both U and V parameters is crucial for accurately modeling the adsorption processes, which are essential for catalysis and environmental applications. These findings highlight the importance of considering both on-site and inter-site electron interactions to achieve a comprehensive understanding of the surface chemistry of transition metal oxides, with an impact on applications of the Fe<inf>3</inf>O<inf>4</inf> (001) surface chemistry. © 2025 The Authors},

abstract = {In this work, an electrochemical biosensor is prepared based on few-layer bismuthene hexagons (FLBHs) and a water-soluble BODIPY (BDP) derivative (BDP-NaSO<inf>3</inf>) for early infection diagnosis. In particular, the detection in advance of a virus sequence in nasopharyngeal swab samples was developed. The combination of the FLBHs and BDP-NaSO<inf>3</inf> facilitates the direct, sensitive, and specific detection of gene viruses without the need for any prior amplification step. This work demonstrates that the FLBHs provide an improved electrochemical platform for immobilizing thiolated DNA capture probes that increase the sensitivity of the biosensor, while BDP-NaSO<inf>3</inf> serves as a newly powerful electrochemical indicator of the hybridization event. As a proof of concept, SARS-CoV-2 was selected as the model virus. The developed biosensor demonstrated selective, rapid, and straightforward detection of the specific sequence RNA-dependent RNA-polymerase (RdRp) of SARS-CoV-2 with a detection limit of 4.97 fM and a linear range from 16.6 fM to 100 fM. Furthermore, this platform successfully detects the virus directly in nasopharyngeal swab samples with a viral load of at least 19 Cts without being subjected to any prior amplification stage. Finally, the high stability of the biosensor response, which has been working under ambient conditions for over one month, the selectivity and rapidity for specific virus detection, and the requirement of low-volume samples for the determination are remarkable characteristics that make it ideal for its potential application in clinical diagnosis in point-of-care settings. © 2025 The Royal Society of Chemistry.},

abstract = {This work presents a comprehensive reaction and kinetic model of the pyrite thin films formation by sulfuration of Fe monosulfides when a molecular sulfur (S<inf>2</inf>) atmosphere is used. This investigation completes the results already published on the explanation and interpretation of the sulfuration process that transforms metallic iron into pyrite. It was previously shown that the monosulfide species (i.e., orthorhombic and hexagonal pyrrhotite phases) are intermediate phases in the sulfuration reaction. Based on experimental data we now show that the sulfuration of pyrrhotite to pyrite takes place in two distinct stages: (i) conversion of orthorhombic pyrrhotite to pyrite (Fe<inf>1-x</inf>S$^textrmO$ → FeS<inf>2</inf>) while the hexagonal pyrrhotite (Fe<inf>1-x</inf>S$^textrmH$) phase remains unaltered, and (ii) final transformation of hexagonal pyrrhotite to pyrite (Fe<inf>1-x</inf>S$^textrmH$ → FeS<inf>2</inf>). Both processes occur via interstitial sulfur diffusion through the previously formed pyrrhotite layer. Consequently, the monosulfide is sulfurated at the internal Fe<inf>1-x</inf>S/FeS<inf>2</inf> interface. The reaction mechanism at each stage has been validated using the corresponding kinetic model to fit the experimental data on time evolution of Fe<inf>1-x</inf>S and FeS<inf>2</inf> layers thicknesses and some of the film transport properties. The concluding global reaction mechanism proposed in some of our former papers and completed here (Fe → Fe<inf>1-x</inf>S → FeS<inf>2</inf>) can explain the resulting microstructure of the pyrite films (i.e., Kirkendall effect and formation of a porous layer in the film). Simultaneously, it also justifies the presence of intrinsic defects, such as iron and sulfur vacancies, and the accumulation of interstitial sulfur at the film grain boundaries. The conductivity of pyrite films is tentatively explained using a two-band model where the changes in the Seebeck coefficient and the S/Fe ratio during the pyrite recrystallization stage can be successfully explained. © 2025 The Authors.

abstract = {The interface of ice with solids plays an exceptionally important role on a wide variety of natural phenomena, such as the melting of permafrost, sliding of glaciers or frost heaving, as well as on many important technological applications such as windmills, car tires, or aircrafts. In this work, we perform a systematic computer simulation study of ice premelting and explore the thickness and structure of quasi-liquid layers formed at the interface of ice with substrates of different hydrophilicities. Our study shows that interfacial premelting occurs systematically on neutral substrates of whatever hydrophilicity, forming films of limited thickness for substrates with contact angles larger than ca. 50° but exhibiting complete interfacial premelting at smaller contact angles. Contrary to most experimental studies, we focus not only on the premelting behavior with temperature, but also with pressure, which is a matter of relevance in important situations such as ice friction. Our study is cast within a rigorous framework of surface thermodynamics, which allows us to show that the premelting film structure is a function of a single thermodynamic variable. By this token we are able to relate properties measured along an isobar, with premelting films at arbitrary temperature and pressure. Our results are also exploited to study ice adhesion, with a view to the understanding of icephobicity. We find that adhesion strength in atomically smooth surfaces is 1 to 2 orders of magnitude larger than those found in experiments, and conjecture that the reason is substrate roughness and the presence of organic adsorbents. Our theoretical framework also allows us to exploit our results on interfacial premelting in order to gain insight into heterogeneous ice nucleation. Our results show that apolar smooth substrates of whatever hydrophilicity are unlikely nucleators, and that too large hydrophilicity conspires also against ice nucleation. Furthermore, we exploit our statistical-thermodynamic framework to shed light on the nature of the surface intermolecular forces promoting interfacial premelting, and provide a model to predict quasi-liquid layer thickness as a function of the substrate’s hydrophilicity with great potential applications in fields ranging from earth sciences to aircraft engineering. © 2025 American Chemical Society.},

abstract = {The interplay between substrate interactions and electron-phonon coupling in two-dimensional (2D) materials presents a significant challenge in understanding and controlling their electronic properties. Here, we present a comparative study of the structural characteristics, phonon dynamics, and electron-phonon interactions in bulk and monolayer NbSe<inf>2</inf> on epitaxial bilayer graphene (BLG) using helium atom scattering (HAS). High-resolution helium diffraction reveals a (9 × 9)0° superstructure within the NbSe<inf>2</inf> monolayer, commensurate with the BLG lattice, while out-of-plane HAS diffraction spectra indicate a low-corrugated (3√3 × 3√3)30° substructure. By monitoring the thermal attenuation of the specular peak across a temperature range of 100 to 300 K, we determined the electron-phonon coupling constant (λ<inf>HAS</inf>) as 0.76 for bulk 2H-NbSe<inf>2</inf>. In contrast, the NbSe<inf>2</inf> monolayer on graphene exhibits a reduced λ<inf>HAS</inf> of 0.55, corresponding to a superconducting critical temperature (T<inf>C</inf>) of 1.56 K according to the MacMillan formula, consistent with transport measurement findings. Inelastic HAS data provide, besides a set of dispersion curves of acoustic and lower optical phonons, a soft, dispersionless branch of phonons at 1.7 meV, attributed to the interface localized defects distributed with the superstructure period, thus termed Moiré phonons. Our data show that Moiré phonons contribute significantly to the electron-phonon coupling in monolayer NbSe<inf>2</inf>. These results highlight the crucial role of the BLG in the electron-phonon coupling in monolayer NbSe<inf>2</inf>, attributed to enhanced charge transfer effects, providing valuable insights into substrate-dependent electronic interactions in 2D superconductors. © 2025 American Chemical Society.},

The films exhibit improved crystalline quality when deposited in pure N<inf>2</inf> at 100 °C. Rutherford Backscattering Spectrometry reveals non-stoichiometric films with Cu/N ratios close to 3. The work function showed by the films deposited in N<inf>2</inf>/Ar is approximately 4.45 eV, while for those deposited in pure N<inf>2</inf>, the values range from 4.30 to 4.62 eV. Optical properties show a high absorbance and a variable refractive index depending on the deposition conditions. Lastly, the Cu<inf>3</inf>N films deposited at 100 °C in pure N<inf>2</inf> exhibit enhanced photocurrent and photosensitivity of 3.78 × 10$^textrm−8$ A and 9644.9 %, respectively, at 10 V and using AM1.5G as light source.

However, their strong tendency to crystallize has hindered both the study and practical applications of amorphous Bi and Bi-Sb alloys.

Structural characterization and electrical resistivity measurements (2-300 K) revealed that, while amorphization and superconductivity were not achieved, melt-spun samples exhibited an order of magnitude higher conductivity than thermally evaporated ones. Moreover, ion-induced disorder further improved electrical conductivity, particularly in Bi<inf>90</inf>Sb<inf>10</inf>, highlighting its potential for thermoelectric applications. © 2025 Author(s).},

abstract = {Friction forces are essential for cell movement, yet they also trigger numerous active cellular responses, complicating their measurement in vivo. Here, we introduce a synthetic model designed to measure friction forces between biomimetic membranes and substrates. The model consists of a vesicle with precisely controlled properties, fabricated via microfluidics, encapsulating a single ferromagnetic particle that is magnetically driven to rotate. The rotation of the particle generates a confined rotational flow, setting the vesicle membrane into motion. By adjusting the magnetic field frequency and vesicle size, the rotation frequency of the vesicle can be finely controlled, resulting in a rolling vesicle that functions as an effective tribological tool across a wide frequency range. At low frequencies, molecular contact between the membrane and substrate dominates frictional interactions, which enables determination of the contact friction coefficient. At higher frequencies, lubrication becomes predominant, causing the vesicles to slip rather than roll. Adjusting membrane fluidity and incorporating specific ligand-receptor interactions within this model will enable detailed studies of frictional forces in more complex biomimetic systems, providing key insights into the mechanisms of cell movement and mechanotransduction. © 2025 the Author(s).},

Relaxation to thermal equilibrium is the most important dissipative process, being a key concept for the design of heat engines and refrigerators, contributing to the study of foundational questions of thermodynamics, and being relevant for quantum computing through the process of algorithmic cooling. Despite their importance, the dynamics of these processes are far from being understood. We show that the free relaxation to thermal equilibrium follows intrinsically different paths depending on whether it involves the temperature of the system to increase or to decrease. Our theory is exemplified using the recently developed thermal kinematics based on information geometry theory, utilizing three prototypical examples: A two-level system, the quantum harmonic oscillator, and a trapped quantum Brownian particle, in all cases showing faster heating than cooling under the appropriate conditions. A general understanding is obtained based on the spectral decomposition of the Liouvillian and the spectral gap of reciprocal processes. © 2025 authors.},

abstract = {Connecting two half-filled quantum dots to two superconducting leads induces a competition of bonds, with the dots forming either an interdot exchange bond or two individual Yu-Shiba-Rusinov (YSR) screening bonds with the leads. Defining a qubit using these singlet-parity bonding states provides dot-charge-noise protection, attributed to the chargeless nature of the screening quasiparticles, and magnetic noise protection, as the bonds guard against magnetic polarization. In this paper, we propose embedding a double-quantum-dot (DQD) Josephson junction in parallel with a transmon to enable circuit-quantum-electrodynamics (cQED) measurements and operation of a YSR-bond qubit. We demonstrate that, under realistic parameters, two-tone spectroscopy of the DQD can be performed, revealing a significant parameter regime suitable for qubit operation. Additionally, coherent manipulations of the bond states can be achieved through dot gates and single-shot readout is enabled by measurements of a capacitively coupled resonator. Finally, we analyze noise sources and estimate gate noise on couplings as the primary source of qubit decoherence. Since this qubit is protected against nuclear Overhauser fields and does not rely on spin-orbit interactions for operation, a broader range of material platforms becomes available compared to current Andreev spin qubits. © 2025 authors.

Ethanol glasses were created by physical vapor deposition (PVD) of ethanol molecules as thin films onto a cooled, gold-coated copper substrate in a high-vacuum chamber, at temperatures below ethanol glass transition temperature (T<inf>g</inf> = 97 K). The films, about 1 μm thick, were analyzed using a two-beam laser interferometer to determine their thickness and density. FTIR spectrometry was used to characterize different ethanol phases over a temperature range close to the glass transition and melting points. Results show that varying densities of solid ethanol form with changes in condensation temperature, reaching maximum density around 110 K. When deposition occurs above T<inf>g</inf>, a crystalline phase called “plastic crystal” forms. However, PVD glasses deposited at temperatures slightly below T<inf>g</inf> exhibit an increase in the devitrification temperature (T<inf>on</inf>), suggesting that these samples form more kinetically stable, amorphous ethanol structures. © 2025 Elsevier B.V.},

abstract = {Sphingomyelin (SM) is the most abundant sphingolipid in mammalian cells. It contains a phosphorylcholine headgroup, which makes SM an analog of the (glycerol-containing) phosphatidylcholines. Palmitoyl (C16:0) SM bilayers in excess water exhibit a thermotropic transition from the ripple to the fluid phase centered at ≈41 °C. In phosphatidylcholines, as in most phospholipids, the ripple-to-fluid transition is fully reversible and virtually free of hysteresis. In this paper, however, the corresponding transition was assessed in aqueous SM by infrared (IR) spectroscopy, a technique detecting molecular vibrations. Vibrational spectra as a function of temperature revealed thermotropic phase transitions. When the samples were successively heated up and cooled down, a clear hysteresis was detected. The cooling transition started at the same temperature as the heating one, but the end-point, in terms of IR band position, was clearly different. Hysteresis was particularly visible in the shift of the IR Amide I band, associated with the lipid polar headgroup, and it was rate-independent, within a wide range of heating/cooling rates (from 5.5 °C/min to less than 0.05 °C/min). Atomistic computer simulations of the molecular dynamics provided information consistent with the IR data. In addition, it showed that the in-plane arrangement of SM bilayers displays a significant amount of hexatic order, and that the hexatic order parameter, reflecting primarily polar headgroup ordering, exhibited the same kind of hysteresis described by IR. Rate-independent hysteresis allows the development of durable memories; therefore, the observations in this paper could lead to novel applications of lipid assemblies. © 2025 Author(s).},

abstract = {We explore the Mott transition in orthorhombic diamond lattices relevant to (ET)Ag4(CN)5 molecular compounds. The noninteracting phases include nodal line, Dirac and/or Weyl semimetals depending on the strength of spin-orbit coupling, and the degree of dimerization of the lattice. Based on an extension of slave-rotor mean-field theory which accounts for magnetic order, we find a transition from a semimetal to a paramagnetic Mott insulator at a critical onsite Coulomb repulsion Uc, which becomes Néel ordered at a larger Ucm>Uc. The resulting intermediate Mott phase is a U(1) quantum spin liquid (QSL) consisting on spinons preserving the nodal structure of the nearby semimetallic phases. While the QSL can be regarded a nodal-line Mott insulator (NLMI) in the absence of spin-orbit interaction (SOI), it behaves as a Dirac Mott insulator for nonzero SOI. An analysis of the Green's function in the NLMI shows how the zeros follow the spinon nodal-line bands carrying the topology while the poles describe the Hubbard bands. Our results are relevant to recent observations in (ET)Ag4(CN)5 molecular compounds in which the ambient pressure Néel ordered Mott insulator is gradually suppressed until semimetallic behavior arises at larger pressures. © 2025 American Physical Society.},

abstract = {Upconverting particles (UCPs), renowned for their capability to convert infrared to visible light, serve as invaluable imaging probes. Furthermore, their responsiveness to diverse external stimuli holds promise for leveraging UCPs as remote multiparametric sensors, capable of characterizing medium properties in a single assessment. However, the utility of UCPs in multiparametric sensing is impeded by crosstalk, wherein distinct external stimuli induce identical alterations in UCP luminescence, hindering accurate interpretation, and yielding erroneous outputs. Overcoming crosstalk requires alternative strategies in upconverting luminescence analysis. In this study, it is shown how a single spinning NaYF<inf>4</inf>:Er$^textrm3+$, Yb$^textrm3+$ upconverting particle enables simultaneous and independent readings of temperature and viscosity. This is achieved by decoupling thermal and rehological measurements—employing the luminescence of thermally-coupled energy levels of Er$^textrm3+$ ions for thermal sensing, while leveraging the polarization of luminescence from non-thermally coupled levels of Er$^textrm3+$ ions to determine viscosity. Through simple proof-of-concept experiments, the study validates the capability of a single spinning UCP to perform unbiased, simultaneous temperature, and viscosity sensing, thereby opening new avenues for advanced sensing in microenvironments. © 2024 The Author(s).

abstract = {In the pursuit of enhancing cancer treatment efficacy while minimizing side effects, near-infrared (NIR) photothermal therapy (PTT) has emerged as a promising approach. By using photothermally active nanomaterials, PTT enables localized hyperthermia, effectively eliminating cancer cells with minimal invasiveness and toxicity. Among these nanomaterials, gold nanostars (AuNS) stand out due to their tunable plasmon resonance and efficient light absorption. This study addresses the challenge of measuring nanoscale temperatures during AuNS-mediated PTT by employing X-ray absorption spectroscopy (XAS) within 3D tumor spheroids. It also aims to investigate the heat generated at the nanoscale and the resultant biological damage observed at a larger scale, utilizing confocal microscopy to establish connections between AuNS heat generation, tissue damage, and their impacts on cellular structure. These nanoscale and microscale thermal effects have been compared with macroscopic values obtained from infrared thermography, as part of a multiscale thermal analysis. The findings underscore the efficacy of AuNS in enhancing PTT and provide insights into the spatial distribution of thermal effects within tumor tissues. This research advances the understanding of localized hyperthermia in cancer therapy and underscores the potential of AuNS-based PTT for clinical applications. © 2024 The Author(s).

abstract = {The optical constants of magnesium (Mg) based films, such as the complex refractive index, are poorly reported in the literature. Consequently, this work presents two self-consistent ellipsometry models capable of determining the optical constants of electron beam evaporated Mg thin films of different thicknesses within a wavelength range from 250 to 1600 nm. These models were validated by fitting spectroscopic ellipsometry measurements at three different incident angles and reflectance measurements. The optical constants of the thinnest film indicate absorption losses due to the influence of voids observed in Field Emission Gun-Scanning Electron Microscopy images. When these voids are considered in the ellipsometry model, a reduction in the extinction coefficient (k) from 4.4 to 3.6 at a wavelength of 800 nm is observed. Thicker films present a different morphology resulting in a drastic change in the optical response leading to reflectivity and k reduction. © 2025 Elsevier B.V.},

abstract = {The use of biodegradable active materials is being explored as a strategy to reduce food loss and waste. The aim is to extend the shelf life of food and to ensure biodegradation when these materials are discarded. The utilization of biodegradable polymers remains limited due to their inherent properties and cost-effectiveness. An alternative approach involves the fabrication of bionanocomposites, which offer a potential solution to address these challenges. Therefore, this study investigates the production of a polyhydroxybutyrate/biochar/clay/essential oil (Tepa:Eugenol) bionanocomposite with antioxidant and antimicrobial properties. The morphological, physicochemical, and antioxidant properties of the materials were evaluated in comparison to those of the original PHB. The materials obtained showed a porous surface with cavities, associated with the presence of biochar. It was also determined that it presented an intercalated–exfoliated morphology by XRD. Thermal properties showed minor improvements over those of PHB, indicating that the components did not substantially influence properties such as crystallization temperature, decomposition temperature, or degree of crystallinity; the melting temperature decreased up to 11%. In addition, the PHB/biochar_7/MMT-OM_3/EO_3 bionanocomposites showed a tendency toward hydrophobicity and the highest elastic modulus with respect to PHB. Finally, all essential-oil-loaded bionanocomposites exhibited excellent antioxidant properties against DPPH and ABTS radicals. The results highlight the potential of these bionanocomposites for the development of antioxidant active packaging. © 2025 by the authors.},
