Hydrophilic Janus Micelles from an ABC Triblock Copolymer
We describe the creation of an amphiphilic triblock copolymer that drives lateral phase separation within micelle coronas. The design combines a hydrophobic poly(lactide) (PLA) core ‑forming block with two distinct hydrophilic ...
Characterization of high-intensity storms in the Metropolitan Area of Barcelona (2014–2022)
Urban coastal areas along the Mediterranean are exposed to short-duration convective rainfall, producing infrastructure disruptions and flood-related impacts. This study analyzes 45 rainfall episodes in the Metropolitan ...
Analyse d’une alerte massive arrivée tardivement lors des inondations survenues à Valence (Espagne) le 29 octobre 2024.
Les inondations survenues le 29 octobre 2024 au sud de Valence (Espagne) ont entraîné un lourd bilan humain (229 personnes décédées) et matériel (22 milliards d’euros de dégâts). Les intensités des pluies ont entraîné des ...
Decoding the Conformation of Polylactic Acid in Block Copolymer Micelles
Understanding how molecular features dictate the self-assembly of amphiphilic block copolymers into well-defined nanostructures is essential for the rational design of advanced soft materials. However, the large number of ...
Rheotaxial growth of semiconductor thin films
The efficiency of thin film solar cells depends to a large extent on the crystalline grain size. The increase of the latter can be obtained by rheotaxy, i.e. the growth of thin films on a liquid metallic layer. In this ...
Roadmap on Optics and Photonics for Security and Encryption
In 1994, Javidi and Horner published a paper in Optical Engineering that highlighted the ability of free space optical systems to manipulate sensitive data for authentication purposes. The underlying idea was effective yet ...
Analysis of the behavior of highly focused, radially coherent Dirichlet sources
We introduce a novel class of electromagnetic light sources that exhibit radial coherence, a degree of coherence characterized by a Dirichlet kernel, and with radial or azimuthal polarization. We provide a mathematical ...
Method for reducing specular reflections in Mueller matrix imaging
Mueller matrix polarimetry has emerged as a powerful tool for non-destructiveoptical analysis of biological tissues and bioorganic materials, offering detailed insights intopolarization-specific properties such as ...
Enhancing hydrogen evolution: Carbon nanotubes as a scaffold for Mo2C deposition via magnetron sputtering and chemical vapor deposition
This study presents an innovative approach to fabricating carbon nanotubes (CNTs) through magnetron sputtering and chemical vapor deposition (CVD). These CNTs serve as a robust structural scaffold for the deposition of ...
The minimal chemotactic cell
The movement of cells and microorganisms in response to chemical gradients (chemotaxis) has played an essential role in the evolution of many biological processes. Cellular navigation works via the holistic assembly of ...
Rapid amyloid-β clearance and cognitive recovery through multivalent modulation of blood–brain barrier transport
The blood‒brain barrier (BBB) is a highly selective permeability barrier that safeguards the central nervous system (CNS) from potentially harmful substances while regulating the transport of essential molecules. Its ...
Meteorological factors and incidence of COVID-19 during the FIRST wave of the pandemic in Catalonia (Spain): A multi-county study
The transmission of coronaviruses can be affected by several factors, including the climate. Due to the rapid spread of COVID-19 and the urgent need for rapid responses to contain the pandemic, it is essential to understand ...
C60 fullerene as an on-demand single photon source at room temperature
Single photon sources are fundamental for applications in quantum computing, secure communication, and sensing, as they enable the generation of individual photons and ensure strict control over photon number statistics. ...
Responsive brushes and gels as components of soft nanotechnology<br />
Progress in the development of generic molecular devices based on responsive polymers is discussed. Characterisation of specially synthesised polyelectrolyte gels, “grafted from” brushes and triblock copolymers is reported. ...
Thermoplasmonic Polymersome Membranes by In Situ Synthesis
Thermoplasmonic nanoparticles, known for releasing heat upon illumination, find diverse applications in catalysis, optics, and biomedicine. Incorporating plasmonic metals within organic vesicle membranes can lead to the ...
Efficient flexible electrodes for lithium-ion batteries utilizing well-dispersed hybrid Mo2C nanoparticles on vertically-oriented graphene nanowalls
Flexible lithium-ion batteries (LIBs) have gained significant interest as potential power source solutions for wearable and flexible electronic devices. However, the fabrication of flexible LIBs with optimal flexibility, ...
Spin-orbit entanglement driven by the Jahn-Teller effect
Spin-orbit entanglement in 4d and 5d transition metal systems can enhance electronic correlations, leading to nontrivial ground states and the emergence of exotic excitations. There is also an interest to investigate ...
Floods in the Pyrenees: A global view through a regional database
This paper shows the first systematic datasetof flood episodes referring to the entire Pyrenees massif,named PIRAGUA_flood, which covers the period 1981–2015 (available at http://hdl.handle.net/10261/270351, lastaccess: ...
Internal variability of the winter North Atlantic Oscillation longitudinal displacements
The winter North Atlantic Oscillation (NAO), one of the leading modes of atmospheric variability in the Northern Hemisphere and key driver of surface climate anomalies, was long considered to be spatially stable. Yet, its ...
Challenges for drought assessment in the Mediterranean region under future climate scenarios
Droughts can have strong environmental and socio-economic impacts in the Mediterranean region, in particular for countries relying on rain-fed agricultural production, but also in areas in which irrigation plays an important ...
