Surface modification of silicon nanowires via drop-casting for high-performance Li-ion battery electrodes: SiNWs decorated with molybdenum oxide nanoparticles
The functionalization of molybdenum oxide (MoO3) nanoparticles is presented as a method to significantlyenhance the cycling stability of lithium-ion battery (LIB) anodes based on silicon nanowire (SiNW) arrays.Transition-metal ...
Superparamagnetic nanoparticles with efficient near-infrared photothermal effect at the second biological window
Superparamagnetic nanoparticles (iron oxide nanoparticles¿IONs) are suitable for hyperthermia after irradiating with radiofrequency radiation. Concerning the suitability for laser ablation, IONs present a low molar absorption ...
Spectroscopic ellipsometry of very rough surfaces
This work expands the use of spectroscopic ellipsometry to surfaces with roughness that is similar to or larger than the wavelength of the incident light. By using a custom-built spectroscopic ellipsometer and varying 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, ...
Comprehensive analysis of MAX phase and MXene materials for advanced photocatalysis, electrocatalysis and adsorption in hydrogen evolution and storage

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 ...
Ex Vivo Permeation of Carprofen Vehiculated by PLGA Nanoparticles through Porcine Mucous Membranes and Ophthalmic Tissues
(1) Background: Carprofen (CP), 2-(6-chlorocarbazole) propionic acid, is used as an anti-inflammatory, analgesic and anti-pyretic agent and it belongs to the family of non-steroidal anti-inflammatory drugs (NSAIDs). CP has ...
Reply to 'Comment on López-Yerena et al. 'Absorption and intestinal metabolic profile of oleocanthal in rats' Pharmaceutics 2020, 12, 134'
Recently, in February 2020, we published a study exploring the intestinal absorption and metabolism of oleocanthal (OLC) in rats. A single-pass intestinal perfusion technique (SPIP) was used, involving simultaneous sampling ...
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 ...
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 ...
Memantine loaded PEGylated biodegradable nanoparticles for the treatment of glaucoma
Glaucoma is a multifactorial neurodegenerative disease associated with retinal ganglion cells (RGC) loss. Increasing reports of similarities in glaucoma and other neurodegenerative conditions have led to speculation that ...
Multifunctional Serine Protease Inhibitor-Coated Water-Soluble Gold Nanoparticles as a Novel Targeted Approach for the Treatment of Inflammatory Skin Diseases
The overexpression and increased activity of the serine protease Kallikrein 5 (KLK5) is characteristic of inflammatory skin diseases such as Rosacea. The use of inhibitors of this enzyme¿such as 4-(2-aminoethyl)benzenesulfonyl ...
The Involvement of Peripheral and Brain Insulin Resistance in Late Onset Alzheimer's Dementia
Nowadays, Alzheimer's disease (AD) is a severe sociological and clinical problem. Since it was first described, there has been a constant increase in its incidence and, for now, there are no effective treatments since ...
PEGylated PLGA nanospheres optimized by design of experiments for ocular administration of dexibuprofen in vitro, ex vivo and in vivo characterization
Dexibuprofen-loaded PEGylated PLGA nanospheres have been developed to improve the biopharmaceuti-cal profile of the anti-inflammatory drug for ocular administration. Dexibuprofen is the active enantiomerof ibuprofen and ...
Memantine loaded PLGA PEGylated nanoparticles for Alzheimer's disease: in vitro and in vivo characterization
Background: Memantine, drug approved for moderate to severe Alzheimer's disease, has not shown to be fully efective. In order to solve this issue, polylactic-co-glycolic (PLGA) nanoparticles could be a suitable solution ...
Cationic supramolecular hydrogels for overcoming the skin barrier in drug delivery
A cationic bis‐imidazolium‐based amphiphile was used to form thermoreversible nanostructured supramolecular hydrogels incorporating neutral and cationic drugs for the topical treatment of rosacea. The concentration of the ...
Role of c-Jun N-Terminal Kinases (JNKs) in Epilepsy and Metabolic Cognitive Impairment
Previous studies have reported that the regulatory function of the different c-Jun N-terminal kinases isoforms (JNK1, JNK2, and JNK3) play an essential role in neurological disorders, such as epilepsy and metabolic-cognitive ...
