Aggregation state and magnetic properties of magnetite nanoparticles controlled by an optimized silica coating
The control of magnetic interactions is becoming essential to expand/improve the applicability of magnetic nanoparticles (NPs). Here, we show that an optimized microemulsion method can be used to obtain homogenous silica ...
On Gaussian curvature and membrane fission
We propose a three-dimensional mathematical model to describe dynamical processes of membrane fssion. The model is based on a phase feld equation that includes the Gaussian curvature contribution to the bending energy. ...
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, ...
Comprehensive analysis of MAX phase and MXene materials for advanced photocatalysis, electrocatalysis and adsorption in hydrogen evolution and storage
Over the past twenty-five years, MAX phases and their derivatives, MXenes, have become a focal point in materials research. These compounds seamlessly blend ceramic and metallic properties, offering high thermal and ...
Towards the real-time measurement of Ultrasound Fields by combining Schlieren Tomography and Wavefront Sensing
Recent advances in ultrasound generation such as ultrasonic holography and acoustic tweezers require methods for the fast characterization of pressure fields. Typically, this can be achieved by using a hydrophone, but the ...
Stochastic modulation evidences a transitory EGF-Ras-ERK MAPK activity induced by PRMT5
The extracellular signal-regulated kinase (ERK) mitogen-activated protein kinase (MAPK) pathway involves a three-step cascade of kinases that transduce signals and promote processes such as cell growth, development, and ...
Nanostructured materials for photodynamic therapy: synthesis, characterization and in vitro activity
Three nanostructured vehicles are proposed as potential carriers for photosensitizers to be used in photodynamic therapy: spherical nanoparticles, hexahedral microparticles and cylindrical magnetic nanorods. A comparative ...
Optical security verification by synthesizing thin films with unique polarimetric signatures
This letter reports the production and optical polarimetric verification of codes based on thin-film technology for security applications. Because thin-film structures display distinctive polarization signatures, this data ...
Controlled formation of shape structures via electrochemical surface modification of Cu(111)
Electrochemical oxidation-reduction processes on copper electrodes and in the presence of different electrolyte anions have been widely explored for the preparation of tailor-made catalysts. Nevertheless, the effect of the ...
Laser-induced forward transfer: a method for printing functional inks
Laser-induced forward transfer (LIFT) is a direct-writing technique based in the action of a laser to print a small fraction of material from a thin donor layer onto a receiving substrate. Solid donor films have been used ...
Building a molecular PrussianBlueAnalogue FeII/CoIII cube around a Cs+ ion; a preferred, tight, robust, water soluble, and kinetically inert encapsulator
The preparation of a caesium inclusion complex of the molecular cube [{CoIII(Me3-tacn)}4{FeII(CN)6}4]}]4–, a mixed valent molecular Prussian Blue Analogue bearing bridging cyanido ligands, has been achieved by following a ...
Differentiation of Epoxide Enantiomers in the Confined Spaces of an Homochiral Cu(II) MOF by Kinetic Resolution
TAMOF-1, a homochiral metal-organic framework (MOF) constructed from an amino acid derivative and Cu(II), was investigated as a heterogeneous catalyst in kinetic resolutions involving the ring opening of styrene oxide with ...
Injection locking in an optomechanical coherent phonon source
Spontaneous locking of the phase of a coherent phonon source to an external reference is demonstrated in a deeply sideband-unresolved optomechanical system. The high-amplitude mechanical oscillations are driven by the ...
Transparent and conductive silver nanowires networks printed by laser-induced forward transfer
Networks of silver nanowires (Ag-NWs) can be electrically conductive and optically transparent at the same time. Thus, Ag-NWs are promising candidates for substituting transparent and conductive oxides like indium-tin-oxide. ...
