Rapid detection of olive oil blends using a paper-based portable microfluidic platform
(Elsevier, 2021)
This paper presents an application of a portable microfluidic platform based on a filter paper on which multi-walled carbon nanotubes were deposited to quickly determine the quality of olive oil by measuring electrical ...
Field Effect and Local Gating in Nitrogen‐Terminated Nanopores (NtNP) and Nanogaps (NtNG) in Graphene
(Wiley, 2021)
Functionalization of electrodes is a wide‐used strategy in various applications ranging from single‐molecule sensing and protein sequencing, to ion trapping, to desalination. We demonstrate, employing non‐equilibrium Green′s ...
Ultrafast humidity sensor based on liquid phase exfoliated graphene
(IOP Publishing, 2020)
Humidity sensing is important to a variety of technologies and industries, ranging from environmental and industrial monitoring to medical applications. Although humidity sensors abound, few available solutions are thin, ...
NMR-based metabolomics for frauds detection and quality control of oregano samples
(Elsevier, 2021)
In this work 1H NMR metabolomics has been employed for quality control of oregano samples. NMR data and morphological analysis (MA) were combined by PCA, obtaining a model able to individuate non-marketable samples, and ...
Bio-membrane based on modified cellulose, lignin, and tannic acid for cation and oxyanion removal: Experimental and theoretical study
(Institution of Chemical EngineersElsevier, 2021)
Two optimized methods, based on epoxy-amino reactivity of the Cellulose fibres (Cell) modified with diethylenetriamine (Cell‒DETA), (3-Glycidyloxypropyl)trimethoxysilane (Cell-Glymo), Lignin modified with epichlorohydrine ...
Waste Jute Fabric as a Biosorbent for Heavy Metal Ions from Aqueous Solution
(Springer, 2020)
The influence of the chemical composition on the biosorption potential of waste jute fabric for Ni2+, Cu2+, and Zn2+ was investigated. The raw jute fabric was treated with sodium hydroxide or sodium chlorite to selectively ...
Ionic diffusion in iPP: DC electrical conductivity
(Elsevier, 2020)
This study provides a new insight into the relationships between absorption and adsorption processes that occur during the treatment of iPP in aqueous solutions of metal-chloride salts, as well as the impact of these ...
Electrochemically deposited iridium-oxide: Estimation of intrinsic activity and stability in oxygen evolution in acid solution
(Elsevier, 2021)
Hydrated iridium oxyhydroxide (IrOx) films were electrochemically deposited from an alkaline oxalic solution at constant anodic potentials and by applying a potential cycling protocol, in both cases with variation of the ...
Hybrid material based on subgleba of mosaic puffball mushroom (Handkea utriformis) as an adsorbent for heavy metal removal from aqueous solutions
(Elsevier, 2021)
The alkali treated subglebal tissue of the mosaic puffball (Handkea utriformis) (Sa) and Sa modified with hydroxyapatite (Sa-HAp), obtained by successive ionic layer adsorption and reaction (SILAR) method, were used for ...
Photocatalytic hydrogen evolution over surface-modified titanate nanotubes by 5-aminosalicylic acid decorated with silver nanoparticles
(Elsevier B.V. and The Society of Powder Technology Japan, 2020)
The efficiency of titanate-nanotubes-based photocatalysts towards hydrogen production was studied in the presence of the sacrificial agent, 2-propanol. The highest hydrogen production rate (~120 lmol h 1 g 1 ) was observed ...
