La producció d’oxigen singlet i la seva reactivitat tenen implicacions rellevants en camps que van des de la ciència dels polímers fins a la teràpia fotodinàmica. La recerca s’ha centrat principalment en el desenvolupament ...
Lipid Nanoparticles for the Posterior Eye Segment
This review highlights the application of lipid nanoparticles (Solid Lipid Nanoparticles, Nanostructured Lipid Carriers, or Lipid Drug Conjugates) as effective drug carriers for pathologies affecting the posterior ocular ...
Wireless pulsed nanophotoelectrochemical cell for the ultrafast degradation of organic pollutants
An urgent demand exists for advanced-technologies to efficiently remove persistent organic pollutants from water, while minimizing energy consumption. Here, we introduce an innovative wireless nanophotoelectrochemical ...
Optomechanical Crystals for Spatial Sensing of Submicron Sized Particles
Optomechanical crystal cavities (OMC) have rich perspectives for detecting and indirectly analysing biological particles, such as proteins, bacteria and viruses. In this work we demonstrate the working principle of OMCs ...
Drug-Loaded Supramolecular Gels Prepared in a Microfluidic Platform: Distinctive Rheology and Delivery through Controlled Far-from-Equilibrium Mixing
It is shown here that controlled mixing of a gelator, drug, solvent, and antisolvent in a microfluidic channel leads to faster setting gels and more robust materials with longer release profiles than the physical gels of ...
PrionW: a server to identify proteins containing glutamine/asparagine rich prion-like domains and their amyloid cores
Prions are a particular type of amyloids with the ability to self-perpetuate and propagate in vivo. Prionlike conversion underlies important biological processes but is also connected to human disease. Yeast prions are the ...
Tandem Mn-I Exchange and Homocoupling Processes Mediated by a Synergistically Operative Lithium Manganate
Pairing lithium and manganese(II) to form lithium manganate [Li2Mn(CH2SiMe3)4] enables the efficient direct Mn-I exchange of aryliodides, affording transient (aryl)lithium manganate intermediates which in turn undergo ...
Effect of substituents on the 1O2 production and biological activity of (N^N^N)Pt(py) complexes
Twelve (N^N^N)platinum pyridyl complexes, (N^N^N)Pt(pyF), were synthesised and investigated for their singlet oxygen generation and potential biological activities. They exhibited 1IL and 1MLCT absorption transitions at ...
Three-dimensional Si / vertically oriented graphene nanowalls composite for supercapacitor applications
Three-dimensional (3D) carbon nanostructures are promising architectures to improve both specific capacity and power density of electrochemical energy storage systems. Their open structure and porosity provide a large space ...
Direct evidence of a graded magnetic interface in bi-magnetic core/shell nanoparticles using electron magnetic circular dichroism (e-MCD).
nterfaces play a crucial role in composite magnetic materials and particularly in bimagnetic core/shell nanoparticles. However, resolving the microscopic magnetic structure of these nanoparticles is rather complex. Here, ...
Nanotherapeutics against malaria: A decade of advancements in experimental models
Malaria, caused by different species of protists of the genus Plasmodium, remains among the most common causes of death due to parasitic diseases worldwide, mainly for children aged under 5. One of the main obstacles to ...
Depinning and Collective Dynamics of Magnetically Driven Colloidal Monolayers
We study the collective dynamics of interacting paramagnetic colloids transported via a magnetic ratchet effect above a modulated periodic potential. Upon increasing the modulation frequency, the particles undergo a series ...
