Infrared (IR) camouflage has garnered growing attention with progress in IR detection technology. The emergence of metamaterial with powerful electromagnetic field regulation ability provides an effective solution for th...

Through the integration of semiconductors or complex oxides into metal resonators, tunable metamaterials have been achieved by a change of environment using an external stimulus. Metals provide high conductivity to reali...

In view of the recent increased interest in light-induced manipulation of magnetism in nanometric length scales this work presents metal clusters as promising elementary units for generating all-optical ultrafast magneti...

Se sintetizaron zeolitas microporosas del tipo ZSM-11, con estructura MEL, por cristalización hidrotermal. Estos materiales fueron modificados con la incorporación de metales nobles como Au, Pt y Pd, por impregnación ...

Photoluminescence including fluorescence plays a great role in a wide variety of applications from biomedical sensing and imaging to optoelectronics. Therefore, the enhancement and control of photoluminescence has immens...

Abstract Limited studies have evaluated the influence of redox-related metals on the Alzheimer´s brain. We determined 15 metals in 241 human brain samples obtained from five biobanks. We examined the levels of metals in...

Multicomponent spinel films were deposited on Ag/Si substrates by magnetron sputtering. Two substrate temperatures were used. XRD diffraction measurements show that the layers are composed of three metals oxides (Mn2O3, ...

The common feature of various plasmonic schemes is their ability to confine optical fields of surface plasmon polaritons (SPPs) into subwavelength volumes and thus achieve a large enhancement of linear and nonlinear opti...

Background: Metal-associated free fatty acids (FFAs) on cardiometabolic diseases have rarely been studied. Objective: To investigate metallomics-FFAs relationship, and identify FFAs as potential mediators linking metals ...

Due to their promising properties, surface magneto plasmons have attracted great interests in the field of plasmonics recently. Apart from flexible modulation of the plasmonic properties by an external magnetic...

The interest in transition metal complexes as antitumor agents started in the 1960s with the serendipitous dis- covery of cisplatin. This drug was appr ov ed by the US FDA in the 1970s for its use as a chemotherapeutic a...

In this article, we develop a unified perspective of unidirectional topological edge waves in nonreciprocal media. We focus on the inherent role of photonic spin in nonreciprocal gyroelectric media, i.e. magnetized metal...

Abstract We proposed and analyzed a planar narrow-band absorber based on a bi-layer metal/dielectric structure. The planar absorber uses the Fabry-Pérot resonance and the inherent loss of the metals, for maximum light a...

We review conducting materials like metals, conducting oxides and graphene for nanophotonic applications. We emphasize that metamaterials and plasmonic systems benefit from different conducting materials. Reson...

El uso de productos naturales como suplementos nutricionales y fármacos requiere conocer con exactitud el contenido de algunos metales tóxicos para el hombre, tales como Cd, Pb, As y Hg. El D-OO3 es un principio activo...

Muchos vegetales suelen expresar una serie de péptidos ricos en ácido glutámico y cisteína, denominados fitoquelatinas o péptidos y-EC (y-glutamilcisteína), cuyo nivel se incrementa cuando aquellos son expuestos a ...

Waste from Electrical and Electronic Equipment (WEEE), such as small/big home appliances, TVs, computers and smartphones, has turnedinto a significant and growing pollution issue. WEEE is a complex mixture of materials a...

"High-temperature renewable and industrial heat applications require efficient and compact solutions to address their inherent intermittency. Latent heat thermal energy storage is one such solution, acting as a buffer be...

The global demand for materials and energy grows apace since the middleof last century and no stopping seems feasible in the next decades. Despiteincreasingly strict controls of emissions from anthropogenic sources, thed...

Entre las alteraciones que puede sufrir el complemento cromosómico de una especie, la aneuploidía (pérdida o ganancia de uno o varios cromosomas) reviste particular importancia por su relación etiológica con abortos...

Chitosan is increasingly used as an alternative to synthetic polymers due to its water solubility, biodegradability, and biological activity. In this work, chitosan samples from three suppliers were evaluated and charact...

In order to increase the flexibility of renewable energies and improve their integration into existing energy grids, efficient intermediate storage is necessary. High-purity hydrogen produced in a water electrolysis cell...

En las últimas décadas y con la finalidad de disminuir el problema de la contaminación acuática, sobre todo aquella causada por la presencia de metales pesados, se han buscado técnicas fisicoquímicas y biológicas ...
