(Institute of Electrical and Electronics Engineers Inc., 2020)
-
(Elsevier, 2020)The dolomite coastal aquifer of Balanegra (SE Spain) is the only source of irrigation water in an area of flourishing intensive agriculture. This scenario has consequently led to a severe exploitation of the water resources. ...
-
(Amer Geophysical Union, 2016)Within large uncertainties in the precipitation response to greenhouse gas forcing, the Southeast Pacific drying stands out as a robust signature within climate models. A precipitation decline, of consistent direction but ...
-
Anthropogenic marine debris over beaches: Spectral characterization for remote sensing applications (Elsevier Inc., 2018)Anthropogenic Marine Debris (AMD) is one of the most important pollutants in the oceans. Millions of tons of debris across oceans have created a critical environmental problem. This study presents a novel method aimed to ...
-
(Elsevier B.V., 2019)The intensive management of tree plantations has replaced and fragmented native forests worldwide. A direct consequence of this activity is the creation of new edges, which generate changes in microclimatic conditions in ...
-
(Elsevier, 2020)Silver nanoparticles (Ag NPs) with anti -bacterial effects against the biofilm-producing bacteria Klebsiella pneu- moniae ( K. pneumoniae ) were synthesized using the marine seaweed Gracilaria corticata ( G. corticata ). ...
-
(Univ Fed Rio de Janeiro, 2020)The rise of nanotechnology has allowed the development of several inorganic nanoparticles with strong biocidal properties against bacteria, fungi, and viruses. Among them, silver nanoparticles (AgNPs) stand out as one of ...
-
(Elsevier, 2020)In this study graphene/chitosan nanoparticles (GR/CS NCs) were developed. The homogenous combination of GR and CS was confirmed by FTIR spectroscopy. The combination of CS with GR sheets reduced the XRD intensity of the ...
-
(Elsevier, 2019)In the present investigation functional chitosan/silver nanocomposites (CS/Ag NCs) were successfully synthesized and found to possess favorable antibacterial activity against extended spectrum beta-lactasame (ESBL) producing ...
-
(Elsevier, 2020)Nickel oxide nanoparticles (NiO NPs) were prepared by a chemical reduction method. The physical and morphological observations of NiO NPs were assessed by powder X-ray diffraction, thermogravimetric analysis, Fourier ...
-
(Springer, 2017)The addition of metal-based nanoparticles on carbon nanotubes (CNT) is a relevant method producing multifunctional materials. In this context, CNT were dispersed in an ethanol/water solution containing copper acetate for ...
-
(Springer, 2018)In situ formation of a Cu-(m-phenylenediamine) (Cu-mPD) oligomer complex from copper chloride during the interfacial polymerization process was successfully employed to produce modified thin-film composite reverse osmosis ...
-
(SAGE Publications Inc., 2019)Warfarin and acenocoumarol are used in various cardiovascular disorders to improve the prognosis of patients with thromboembolic disease. However, there is a lack of substantial efficacy and safety data on antithrombotic ...
-
(Elsevier, 2014)In this workwegive a lower bound for the groundstate degeneracy of the antiferromagnetic Ising model in the class of stack triangulations, also known as planar 3-trees. The geometric dual graphs of stack triangulations ...
-
(Amer Physical Soc, 2015)We describe the features of magnonic crystals based upon antiferromagnetic elements. Our main results are that with a periodic modulation of either magnetic fields or system characteristics, such as the anisotropy, it is ...
-
(SAGE, 2015)The addition of metal particles, for instance, silver or copper, into polymer matrices is a relevant strategy producing novel antimicrobial materials. By using two particles with diameters around 10nm and 45 mu m, and ...
-
(MDPI, 2015)Metals, such as copper and silver, can be extremely toxic to bacteria at exceptionally low concentrations. Because of this biocidal activity, metals have been widely used as antimicrobial agents in a multitude of ...
-
(BioMed Central Ltd., 2019)© 2019 The Author(s).Background: Healthcare-associated infections (HAIs) have a major impact on public health worldwide. Particularly, hospital surfaces contaminated with bacterial pathogens are often the origin of both ...
-
(Sociedad Chilena de Infectologia, 2019)This manuscript includes the antiinfective therapeutic resources for immunocompromised patients under chemotherapy by cancer or hematopoietic stem cells transplant (HSCT) receptors. The document presents the antimicrobial ...
