Tailoring Staircase-like Hysteresis Loops in Electrodeposited Tri-segmented Magnetic Nanowires: a Strategy toward Minimization of Interwire Interactions
A new strategy to minimize magnetic interactions between nanowires (NWs) dispersed in a fluid is proposed. Such a strategy consists of preparing trisegmented NWs containing two antiparallel ferromagnetic segments with ...
Precise Size Control of the Growth of Fe3O4 Nanocubes over a Wide Size Range Using a Rationally Designed One-Pot Synthesis
The physicochemical properties of spinel oxide magnetic nanoparticles depend critically on both their size and shape. In particular, spinel oxide nanocrystals with cubic morphology have shown superior properties in comparison ...
Enhanced visible-light-driven peroxymonosulfate activation for antibiotic mineralization using electrosynthesized nanostructured bismuth oxyiodides thin films
The search for non-specific catalysts capable of removing a wide range of organic contaminants remains a key challenge given their increasing presence in aquatic environments. In this ongoing exploration, this work proposes ...
Amyloids in Solid-State Nuclear Magnetic Resonance: Potential causes of the usually low resolution
Amyloids are non-crystalline and insoluble, which imply that the classical structural biology tools, ie, X-ray crystallography and solution nuclear magnetic resonance (NMR), are not suitable for their analysis. In the last ...
Perspectives of the Application of Non-Steroidal Anti-Inflammatory Drugs in Cancer Therapy: Attempts to Overcome Their Unfavorable Side Effects
Non-steroidal anti-inflammatory drugs (NSAIDs) express anti-tumoral activity mainly by blocking cyclooxygenase-2 involved in the synthesis of prostaglandins. Therefore, in the last few decades, many have attempted to ...
Enhanced diffusion and non-Gaussian dynamics in driven magnetic nanoparticles
We investigate the out-of-equilibrium dynamics of paramagnetic colloidal nanoparticles driven above a triangular lattice of cylindrical ferromagnetic domains. We use an external precessing magnetic field to create a dynamic ...
Sugar-lowering drugs for type 2 Diabetes Mellitus and Metabolic Syndrome Review of cassical and new compounds: Part-I
Diabetes mellitus (DM) is a metabolic disorder characterized by chronic hyperglycemia together with disturbances in the metabolism of carbohydrates, proteins and fat, which in general results from an insulin availability ...
Magnetic nanoparticles: from the nanostructure to the physical properties
Some of the synthesis methods and physical properties of iron oxide-based magnetic nanoparticles such as Fe3-xO4 and CoxFe3-xO4 are reviewed because of their interest in health, environmental applications, and ultra-high ...
On the use of Parylene C polymer as substrate for peripheral nerve electrodes
Parylene C is a highly flexible polymer used in several biomedical implants. Since previous studies have reported valuable biocompatible and manufacturing characteristics for brain and intraneural implants, we tested its ...
2D PEA2SnI4Inkjet-Printed Halide Perovskite LEDs on Rigid and Flexible Substrates
Lead-free PEA2SnI4-based perovskite LEDs are successfully inkjet-printed on rigid and flexible substrates. Red-emitting devices (λmax = 633 nm) exhibit, under ambient conditions, a maximum external quantum efficiency ...
Vortex properties in the extended supersolid phase of dipolar Bose-Einstein condensates.
We study the properties of singly quantized linear vortices in the supersolid phase of a dipolar Bose-Einstein condensate at zero-temperature modeling 164Dy atoms. The system is extended in the x−y plane and confined by a ...
Laser-induced forward transfer of conductive screen-printing inks
Laser-induced forward transfer (LIFT), unlike inkjet printing, presents few constrains concerning ink viscosity or loading particle size. This is clearly favorable for printed electronics applications, since high solid ...
Laser-induced forward transfer: fundamentals and applications
Laser-induced forward transfer (LIFT) is a digital printing technique that uses a pulsed laser beam as the driving force to project material from a donor thin film toward the receiving substrate whereon that material will ...
Integrating magnetic capabilities to intracellular chips for cell trapping
Current microtechnologies have shown plenty of room inside a living cell for silicon chips. Microchips as barcodes, biochemical sensors, mechanical sensors and even electrical devices have been internalized into living ...
Nanomedicines for the Delivery of Antimicrobial Peptides (AMPs)
Microbial infections are still among the major public health concerns since several yeasts and fungi, and other pathogenic microorganisms, are responsible for continuous growth of infections and drug resistance against ...
Iron Oxide Nanoparticles in Photothermal Therapy
Photothermal therapy is a kind of therapy based on increasing the temperature of tumoral cells above 42 C. To this aim, cells must be illuminated with a laser, and the energy of the radiation is transformed in heat. Usually, ...
Tunable circular dichroism through absorption in coupled optical modes of twisted triskelia nanostructures
We present a system consisting of two stacked chiral plasmonic nanoelements, so-called triskelia, that exhibits a high degree of circular dichroism. The optical modes arising from the interactions between the two elements ...
Emergence of the stripe-domain phase in patterned permalloy films
The occurrence of stripe domains in ferromagnetic permalloy (Py = Fe20Ni80) is a well-known phenomenon which has been extensively observed and characterized. This peculiar magnetic configuration appears only in films with ...
Arc-discharge synthesis of iron encapsulated in carbon nanoparticles for biomedical applications
The objective of the present work is to improve the protection against the oxidation that usually appears in core@shell nanoparticles. Spherical iron nanoparticles coated with a carbon shell were obtained by a modified ...
Snapshot circular dichroism measurements
Two coherent waves carrying orthogonal polarizations do not interfere when they superpose, but an interference pattern is generated when the two waves share a common polarization. This well-known principle of coherence and ...
