Abstract Poly(lactic acid) (PLA) is a biodegradable and biocompatible polyester widely used in biomedical applications. Unfortunately, this biomaterial suffers from some shortcomings related with the absence of both bioactivity antibacterial capacity. In work, composites PLA either graphene oxide (GO) or thermally reduced (TrGO) were prepared by melt mixing to overcome these limitations. GO TrGO inhibited attachment proliferation Escherichia coli Staphylococcus aureus bacteria depending on...
Here we report the biological synthesis of CdS fluorescent nanoparticles (Quantum Dots, QDs) by polyextremophile halophilic bacteria isolated from Atacama Salt Flat (Chile), Uyuni (Bolivia) and Dead Sea (Israel). In particular, a Halobacillus sp. DS2, strain presenting high resistance to NaCl (3-22%), acidic pH (1-4) cadmium (CdCl2 MIC: 1,375 mM) was used for QDs biosynthesis studies. synthesize in presence concentrations process related with their capacity generate S2- these conditions....
Understanding biological interaction with graphene and hexagonal-boron nitride (h-BN) membranes has become essential for the incorporation of these unique materials in contact living organisms. Previous reports show contradictions regarding bacterial sheets on metals. Here, we present a comprehensive study bacteria copper substrates coated single-layer h-BN. Our results demonstrate that such graphitic coatings substantially suppress between underlying Cu substrates, acting as an effective...
A four-port optical circulator based on two-dimensional square lattice photonic crystals is reported. It simple besides the brief framework. The crystalline geometrical structure of makes 90° non-reciprocal transmissions electromagnetic waves with low insertion loss and high levels isolation by diligence magneto-optic crystals. novel because it uses a resonant cavity design. Also, in comparison to prior models, proposed utilizes crystal cylindrical ferrite section π/4 Faraday angle. finite...
La regulación del trabajo en plataformas digitales es una de las asignaturas pendientes estados- nación sur global, donde factores diferente índole juegan contra para lograr mejorar condiciones quienes laboran dentro. El caso México se distingue por ser regiones socioeconómicas como Uber, tiene uno sus mayores mercados a nivel mundial. Sin embargo, iniciativas que han presentado ante el Congreso la Unión visto afectadas falta interés los conductores y consecuencia ausencia organización...
The deposition of Cu onto SiO2 has been carried out by electron beam evaporation in order to study the interface formation X-ray photoelectron spectroscopy and angle resolved spectroscopy. Shifts binding energy 2p3/2 Si 2p bands, as well LMM kinetic energy, have observed during growth. These changes are indicative a modification coordination number or M–O–M′ cross-linking bonds at interface. Moreover, different states Cu+ Cu2+ (tetrahedral octahedral) detected. Apart from numbers, new...
Biomarkers are the primary indicators of human health. Measurements traditionally rely on targeted binding and assays, which, in turn, specific “labels” that define biomarker or molecule interest. While selective specific, label‐based approaches limit range biomarkers a technology can detect. Technologies detect analyze broad offer versatility, especially rapid repurposing for new targets. Optical technologies label‐free sensing enable noninvasive, minimal‐contact, wearable point‐of‐care...
Abstract A photonic crystal (PhC) based optical component paves a path to the upcoming all-optical computer processors. All components can be realized with help of PhCs. In particular, gates have played major part in development half adders which has lead bloom computing technology. this paper, PhC adder is proposed and brief analysis carried out for different structures lattice patterns. The efficiency device analyzed by providing proper distinct space output power between logical ‘0’ ‘1’...
