Silver nanoparticles-composing alginate/gelatine hydrogel improves wound healing in vivo
Polymer hydrogels have been suggested as dressing materials for the treatment of cutaneous wounds and tissue revitalization. In this work, we report the development of a hydrogel composed of natural polymers (sodium alginate ...
YAT2150: Overcoming limitations of traditional amyloid dyes in aggregation studies
Amyloid fibrils, which are aggregates of misfolded proteins characterized by β-sheet-rich structures, are implicated in several neurodegenerative and systemic pathologies, including Alzheimer’s and Parkinson’s diseases and ...
Association of platelet-rich plasma and auto-crosslinked hyaluronic acid microparticles: approach for orthopedic application
Platelet-rich plasma (PRP) associated with high molecular weight hyaluronic acid (HA) has been clinically used for tissue regeneration in orthopedics. Despite the recognized beneficial clinical outcomes (e.g., early pain ...
Insights into interface and bulk defects in a high efficiency kesterite-based device
This work provides a detailed analysis of a high efficiency Cu2ZnSnSe4 device using a combination of advanced electron microscopy and spectroscopy techniques. In particular, a full picture of the different defects present ...
Optimization, biopharmaceutical profile and therapeutic efficacy of pioglitazone-loaded PLGA-PEG nanospheres as a novel strategy for ocular inflammatory disorders.
PURPOSE: The main goal of this study was to encapsulate Pioglitazone (PGZ), in biodegradable polymeric nanoparticles as a new strategy for the treatment of ocular inflammatory processes. METHODS: To improve their ...
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 ...
Kinetico-mechanistic insights into the photodynamic process of AuI complexes with the CNC6H4NNC6H5 (iso-Ph) azobenzene ligand
A family of neutral isocyanide monoazo AuI complexes [AuCl(iso-Ph)], [Au(C6F5)(iso-Ph)] and [Au(C[triple bond, length as m-dash]Cpy)(iso-Ph)] (iso-Ph being CN–C6H4–N[double bond, length as m-dash]N–Ph) and a closely related ...
The long cross-over dynamics of capillary imbibition
Spontaneous capillary imbibition is a classical problem in interfacial fluid dynamics with a broad range of applications, from microfluidics to agriculture. Here we study the duration of the cross-over between an initial ...
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. ...
Diabetic Retinopathy and Ocular Melanoma: How far we are?
Diabetic retinopathy causes vascular damage to retinal neurons, presenting characteristics of chronic inflammation. The development of new therapies capable of combating vision loss involves knowledge of inflammatory retinal ...
Manipulation of competing ferromagnetic and antiferromagnetic domains in exchange biased nanostructures
Using photoemission electron microscopy combined with x-ray magnetic circular dichroism we show that a progressive spatial confinement of a ferromagnet (FM), either through thickness variation or laterally via patterning, ...
Utilizing biomass-based graphene oxide-polyaniline-Ag electrodes in microbial fuel cells to boost energy generation and heavy metal removal
Although regarded as environmentally stable, bioelectrochemical fuel cells or, microbial fuel cells (MFCs) continue to face challenges with sustaining electron transport. In response, we examined the performance of two ...
Innovative strategies to treat skin wounds with mangiferin: fabrication of transferosomes modified with glycols and mucin
im: The moisturizing properties of glycerol, the penetration enhancing capability of propylene glycol and the bioadhesive properties of mucin were combined to improve the carrier capabilities of transfersomes and the ...
Nonideal optical response of liquid crystal variable retarders and its impact on their performance as polarization modulators
Liquid crystal variable retarders (LCVRs) will be used for the first time in a space instrument, the Solar Orbiter mission of the European Space Agency, as polarization states analyzers (PSAs). These devices will determine ...
The combined use of gold nanoparticles and infrared radiation enables cytosolic protein delivery
Cytosolic protein delivery remains elusive. The inability of most proteins to cross the cellular membrane is a huge hurdle. Here we explore the unique photothermal properties of gold nanorods (AuNRs) to trigger cytosolic ...
Rapid quantification of 3D ultrasound fields with wavefront sensing and Schlieren tomography
The rapid and precise characterization of three-dimensional (3D) pressure fields inside water is paramount for ultrasound (US) applications in fields as relevant as biomedicine and acoustic trapping. The most conventional ...
Electrodeposition of nanostructured Bi2MoO6@Bi2MoO6-x homojunction films for the enhanced visible-light-driven photocatalytic degradation of antibiotics
Complex tunable visible-light-driven Aurivillius-phase-based micro- and nanostructured photocatalysts were fabricated following a novel, scalable, easily implemented sequential process based on electrochemical deposition ...
Effect of a Balanced Concentration of Hydrogen on Graphene CVD Growth
The extraordinary properties of graphene make it one of the most interesting materials for future applications. Chemical vapor deposition (CVD) is the syntheticmethod that permits obtaining large areas ofmonolayer graphene. ...
Flavonoid ‐ enriched plant ‐ extract ‐ loaded emulsion : a novel phytocosmetic sunscreen formulation with antioxidant properties. antioxidants
The aim of this study was to develop a phytocosmetic sunscreen emulsion with antioxidant effect, containing a blend of flavonoid-enriched plant extracts. In vitro sun protection factor, antioxidant activity, skin irritation, ...
In vitro evaluation of degradable electrospun polylactic acid/bioactive calcium phosphate ormoglass scaffolds
