The impact of Mn nonstoichiometry on the oxygen mass transport properties of La0.8Sr0.2MnyO3±δ thin films
Oxygen mass transport in perovskite oxides is relevant for a variety of energy and information technologies. In oxide thin films, cation nonstoichiometry is often found but its impact on the oxygen transport properties is ...
Engineering Cell-Derived Matrices: From 3D Models to Advanced Personalized Therapies
Regenerative medicine and disease models have evolved in recent years from two to three dimensions, providing in vitro constructs that are more similar to in vivo tissues. By mimicking native tissues, cell-derived matrices ...
On the Binding of Congo Red to Amyloid Fibrils
Amyloids are characterized by their capacity to bind Congo red (CR), one of the most used amyloid‐specific dyes. The structural features of CR binding were unknown for years, mainly because of the lack of amyloid structures ...
Physical and photocatalytic properties of sprayed Dy doped ZnO thin films under sunlight irradiation for degrading methylene blue
Dysprosium-doped zinc oxide (ZnO) thin films have been prepared through spray pyrolysis onto glass substrates. Cross-sections of the deposited thin films were assessed through Scanning Electron Microscopy (SEM), showing ...
The template effect of a SiF62- guest drives the formation of a heteroleptic Fe(II) coordination helicate
The anion SiF62− exerts a strong template effect, driving the exclusive assembly of two different bispyridylpyrazolyl ligands into a triple stranded Fe(II) dinuclear heteroleptic helicate, engendering a new class within ...
Integration of a non-precious pyrolyzed Cu-doped ZIF as an oxygen depolarized cathode in an advanced chlor-alkali electrolyzer
Oxygen reduction is the critical step in advanced chlor-alkali electrolysis, which has motivated extensive research in catalyst development for improved efficiency and durability. This study investigates the oxygen reduction ...
Heparin Administered to Anopheles in Membrane Feeding Assays Blocks Plasmodium Development in the Mosquito
Innovative antimalarial strategies are urgently needed given the alarming evolution of resistance to every single drug developed against Plasmodium parasites. The sulfated glycosaminoglycan heparin has been delivered in ...
Thermal noise and optomechanical features in the emission of a membrane-coupled compound cavity laser diode
We demonstrate the use of a compound optical cavity as linear displacement detector, by measuring the thermal motion of a silicon nitride suspended membrane acting as the external mirror of a nearinfrared Littrow laser ...
Polyamide fabric coated with a DHA-loaded chitosan hydrogel for a cosmeto-textile application
Cosmeto-textiles, which allow the administration of molecules when in contact with the skin, are increasingly being developed by cosmetic industries. We have designed an innovative approach for cosmeto-textile products, ...
Magnetic Nanoparticles Cross the Blood-Brain Barrier: When Physics Rises to a Challenge
The blood-brain barrier is a physical and physiological barrier that protects the brain from toxic substances within the bloodstream and helps maintain brain homeostasis. It also represents the main obstacle in the treatment ...
Dynamics of equilibration and collisions in ultradilute quantum droplets
Employing time-dependent density-functional theory, we have studied dynamical equilibration and binary head-on collisions of quantum droplets taking as a case of study droplets made of a 39 K - 39 K Bose mixture. The phase ...
Differential regulation of insulin signalling by monomeric and oligomeric amyloid beta-peptide
Alzheimer's disease and Type 2 diabetes are pathological processes associated to ageing. Moreover, there are evidences supporting a mechanistic link between Alzheimer's disease and insulin resistance (one of the first ...
Memantine for the treatment of dementia. A review on its current and future applications
Alzheimer's disease (AD) is a neurodegenerative disorder characterized by the presence in the brain of extracellular amyloid-β protein (Aβ) and intracellular neurofibrillary tangles composed of hyperphosphorylated tau ...
Ultra rapid in vivo screening for anti-Alzheimer anti-amyloid drugs
More than 46 million people worldwide suffer from Alzheimer's disease. A large number of potential treatments have been proposed; among these, the inhibition of the aggregation of amyloid β-peptide (Aβ), considered one of ...
Characterizing the Hard and Soft Nanoparticle-Protein Corona with Multilayer Adsorption
Nanoparticles (NPs) in contact with biological fluid adsorb biomolecules into a corona. This corona comprises proteins that strongly bind to the NP (hard corona) and loosely bound proteins (soft corona) that dynamically ...
Synergistic enhancement of Raney-Ni catalyst for methane dry reforming viaelectrochemically e ngineered CoNi co-catalyst
Dry reforming of methane (DRM) offers a promising route to convert biogas into syngas while capturing CO₂.However, the harsh reaction conditions (≥700 ◦C) lead to rapid deactivation of conventional Ni-based catalystsdue ...
Photocatalytic H2 production from ethanol aqueous solution using TiO2 with tungsten carbide nanoparticles as co-catalysts. International Journal of Hydrogen Energy 2020,
The effect of tungsten carbide as co-catalyst in the photocatalytic H2 production from ethanol aqueous solutions (25% v/v) is reported. The photocatalytic H2 production using WC/TiO2 systems, in which tungsten carbide NPs ...
Excluded Volume Causes Integer and Fractional Plateaus in Colloidal Ratchet Currents
We study the collective transport of paramagnetic colloids driven above a magnetic bubble lattice by an external rotating magnetic eld. We measure a direct ratchet current which rises in integer and fractional steps with ...
Solid-state organization of n-type carbazole-based semiconductors for organic thin-film transistors
The development of new organic semiconductors has been mainly led by the search for new π-conjugated cores, but recently the use of flexible side chains is attracting more and more attention to control the molecular packing ...
Enhancement of the Elastocaloric Performance of Natural Rubber by Forced Air Convection
We study the enhancement of the elastocaloric effect in natural rubber by using forced air convection to favour heat extraction during the elongation stage of a stretching–unstretching cycle. Elastocaloric performance is ...
