Electrochemical POC device for fast malaria quantitative diagnosis in whole blood by using magnetic beads, Poly-HRP and microfluidic paper electrodes
© 2019 Elsevier B.V. Malaria, a parasitic infection caused by Plasmodium parasites and transmitted through the bite of infected female Anopheles mosquitos, is one of the main causes of mortality in many developing countries. ...
Development of Chitosan/Silver Sulfadiazine/Zeolite composite flms for wound dressing
Biopolymeric films with silver sulfadiazine (AgSD) are proposed as an alternative to the occlusive AgSD-containing creams and gauzes, which are commonly used in the treatment of conventional burns. While the recognized ...
Electrodeposited BiVO4-based photoanodes for an energy-efficient photo-assisted CO2-to-formate conversion
The development of efficient photoanodes that reduce external energy requirements for the electrochemical conversion of CO2 to formate is essential for the future implementation of this technology. In this work, we explore ...
Bismuth oxyiodide-based composites for advanced visible-light activation of peroxymonosulfate in pharmaceutical mineralization
The presence of pharmaceutical pollutants in water bodies represents a significant environmental and public health concern, largely due to their inherent persistence and potential to induce antibiotic resistance. Advanced ...
Electrodeposited manganese oxides as efficient photocatalyst for the degradation of tetracycline antibiotics pollutant
One of the important environmental challenges of the 21st century is the effective removal of pollutants from the aquatic environment. In this study, electrodeposited manganese oxides (MnyOx) films were applied as ...
Chemical vapour deposited ZnO nanowires for detecting Ethanol and NO2
Randomly oriented ZnO nanowires were grown directly onto alumina substrates having platinum interdigitated screen-printed electrodes via the chemical vapor deposition method using Au as catalyst. Three different Au film ...
Efficient spin pumping into metallic SrVO3 epitaxial films
Spin pumping across interfaces between metallic SrVO3, where V is a 3d1 ion, epitaxial thin films and ferromagnetic Ni80Fe20 is reported. Data shows an efficient spin pumping with a spin mixing conductance value (g↑↓ = ...
Adaptation of targeted nanocarriers to changing requirements in antimalarial drug delivery
The adaptation of existing antimalarial nanocarriers to new Plasmodium stages, drugs, targeting molecules, or encapsulating structures is a strategy that can provide new ...
The effect of anode support on the electrochemical performance of microtubular solid oxide fuel cells fabricated by gel-casting
Different cell configurations of anode-supported microtubular solid oxide fuel cells (mT-SOFCs) using samaria-doped ceria (SDC) as the electrolyte were fabricated. Several cells were processed varying the porosity and wall ...
Highly sensitive SnO2 nanowire network gas sensors
In this work we present a methodology for the localized growth of nanowires on prespecified areas of microhotplates that allows to independently adjust the device's resistance and its response to the gas. This is achieved ...
Magnetic nanoemulsions: comparison between nanoemulsions formed by ultrasonication and by spontaneous emulsification
Nanoemulsions are particularly suitable as a platform in the development of delivery systems. The type of nanoemulsion with a higher stability will offer an advantage in the preparation of a delivery system for lipophilic ...
Aggregation state and magnetic properties of magnetite nanoparticles controlled by an optimized silica coating
The control of magnetic interactions is becoming essential to expand/improve the applicability of magnetic nanoparticles (NPs). Here, we show that an optimized microemulsion method can be used to obtain homogenous silica ...
On Gaussian curvature and membrane fission
We propose a three-dimensional mathematical model to describe dynamical processes of membrane fssion. The model is based on a phase feld equation that includes the Gaussian curvature contribution to the bending energy. ...
Efficient flexible electrodes for lithium-ion batteries utilizing well-dispersed hybrid Mo2C nanoparticles on vertically-oriented graphene nanowalls
