Level of decoupling between economic growth and environmental pressure on Earth-system processes
Ensuring economic growth without challenging the Earth's resiliency is crucial to achieving sustainable development. Capitalizing on the planetary boundaries framework as the limits to growing safely, here we present a ...
Preparation and applications of organo-silica hybrid mesoporous silica nanoparticles for the co-delivery of drugs and nucleic acids
Combination therapies rely on the administration of more than one drug, with independent mechanisms of action, aiming to enhance the efficiency of the treatment. For an optimal performance, the implementation of such ...
High-Compression Crash Simulations and Tests of PLA Cubes Fabricated Using Additive Manufacturing FDM with a Scaling Strategy
Impacts due to drops or crashes between moving vehicles necessitate the search for energy absorption elements to prevent damage to the transported goods or individuals. To ensure safety, a given level of acceptable ...
Experiencias culturales novedosas para la Barcelona actual
El llamado ‘turismo cultural’ necesita con urgencia un espacio de refl exión que controle, evalúe y desarrolle nuevos contenidos y ofertas culturales para tratar de dinamizar un tipo de turismo que necesita nuevos escenarios. ...
Estrategias de precios "online" en hoteles de lujo de Barcelona

Tool for Greener Tourism: Evaluating Environmental Impacts
Travel and tourism are essential to global economies, generating social, economic, and environmental impacts. However, there is a lack of standardized methodologies to assess the environmental footprint of tourist destinations ...
Cluster and Kill: the Use of Clustering-Triggered Emission Materials for Singlet Oxygen Photosensitization in Antimicrobial Photodynamic Therapy
The emergence of light-based technologies is revolutionizing modern medicine and healthcare by enabling precise disease diagnosis and treatment through various luminescent agents and imaging techniques. Despite challenges ...
In Vitro and In Vivo Antimicrobial Activity of Hypochlorous Acid against Drug-Resistant and Biofilm-Producing Strains
The aims of this study were as follows. First, we determined the antimicrobial efficacy of hypochlorous acid (HClO) against bacterial, fungal, and yeast strains growing planktonically and growing in biofilms. Second, we ...
From propenolysis to enyne metathesis: tools for expedited assembly of 4a,8a-azaboranaphthalene and extended polycycles with embedded BN
The synthesis of BN-containing molecules, which have an interesting isosteric relationship to their parent all-C cores, has drawn a great deal of attention as an avenue to alter and tune molecular function. Nevertheless, ...
A Double Payload Complex between Hypericin and All-trans Retinoic Acid in the β-Lactoglobulin Protein
Combined therapies are usually used to treat acne vulgaris since this approach can tackle various foci simultaneously. Using a combination of spectroscopic, computational, and microbiological techniques and methods, herein ...
Fair value versus historical cost-based valuation for biological assets: predictability of financial information
There is an intense debate on the convenience of moving from historical cost (HC) toward the fair value (FV) principle. The debate and academic research is usually concerned with financial instruments, but the IAS 41 ...
BrainBike peptidomimetic enables efficient transport of proteins across brain endothelium
Protein therapeutics cannot reach the brain in sufficient amounts because of their low permeability across the blood–brain barrier. Here we report a new family of bicyclic peptide shuttles, BrainBikes, capable of increasing ...
Nanostructured AABB Zn (II) Phthalocyanines as Photodynamic Agents for Bacterial Inactivation
In this work, the ability of amphiphilic Phthalocyanine (Pc) photosensitizers (PS) (Zn(II)Pcs PS1, PS2, and PS3) to assemble into cationic nanoparticles in water and to photo-inactivate bacterial strains is demonstrated. ...
Enzymatic production of defined chitosan oligomers with a specific pattern of acetylation using a combination of chitin oligosaccharide deacetylases
Chitin and chitosan oligomers have diverse biological activities with potentially valuable applications in fields like medicine, cosmetics, or agriculture. These properties may depend not only on the degrees of polymerization ...
Tailored mechanical performance of fused filament fabricated 316L steel components through printing parameter optimization
