Rapid, easy and catalyst-free preparation of magnetic thiourea-based covalent organic frameworks at room temperature for...

Published in Journal of chromatography. A

The complex and cumbersome preparation of magnetic covalent organic frameworks (COFs) nanocomposites on a small scale limits their application. Herein, a rapid and easy route was employed for the preparation of magnetic thiourea-based COFs nanocomposites. COFs were coated on Fe3O4 nanoparticles at room temperature without a catalyst within approxim...

Acclimation to medium-level non-lethal iron limitation: Adjustment of electron flow around the PSII and metalloprotein e...

Published in Biochimica et biophysica acta. Bioenergetics

The aim of this study was to investigate how acclimation to medium-level, long-term, non-lethal iron limitation changes the electron flux around the Photosystem II of the oceanic diazotroph Trichodesmium erythraeum IMS101. Fe availability of about 5× and 100× lower than a replete level, i.e. conditions common in the natural environment of this cyan...

Detection of inorganic arsenic in rice using a field-deployable method with Cola extraction.

Published in Analytical and bioanalytical chemistry

Rice is a staple food and known to accumulate inorganic arsenic (iAs), which is a class 1 carcinogen to humans. Arsenic field-deployable method kits, designed for water testing, are able to screen iAs in rice, to assure food safety and quick decision-making without the need for laboratory analysis. For the arsenic extraction within the field method...

Multi-Classification and Tree-Based Ensemble Network for the Intrusion Detection System in the Internet of Vehicles.

Published in Sensors (Basel, Switzerland)

The Internet of Vehicles(IoV) employs vehicle-to-everything (V2X) technology to establish intricate interconnections among the Internet, the IoT network, and the Vehicle Networks (IVNs), forming a complex vehicle communication network. However, the vehicle communication network is very vulnerable to attacks. The implementation of an intrusion detec...

Simultaneous measurement of labile As (III) and As (V) in soils combining DGT and HPLC-ICP-MS.

Published in The Science of the total environment

The speciation of arsenic (As) determines its biogeochemistry and ecotoxicity in soils. However, the approach to in situ monitor labile As (III) and As (V) in soils still requires more exploration. In this study, we developed a method for simultaneously obtaining in-situ data on labile As (III) and As (V) in soils using diffusive gradients in thin ...

Content, speciation and in vitro bioaccessibility of trace elements in seaweeds and derived food products

Seaweed products currently emerging in Europe are known to be potentially contaminated by toxic elements. The present study focused on the contents and bioaccessibility of trace elements in seaweed products available in Belgium. A total of 231 samples were collected in markets and As, Cd, Ni, Hg, Pb, I and Se concentrations were measured. Moreover,...

Biofortification of selenium in black soldier fly (Hermetia illucens) prepupae reared on seaweed or selenium enriched su...

Published in Journal of Insects as Food and Feed

Selenium (Se) is an essential trace element for livestock. The element can be supplemented to feed in inorganic or organic Se forms, where the chemical form in the diet affects the accumulation of Se in animal tissues. Insects are known to be natural bioaccumulators of different nutrients, but no studies have so far looked up on the capacity of ins...

Simple and reliable determination of total arsenic and its species in seafood by ICP-MS and HPLC-ICP-MS.

Published in Food chemistry

Quantitative, rapid, selective and sensitive methods for the determination of total arsenic (tAs) and six arsenic compounds (arsenite (As(III)), arsenate (As(V)), arsenobetaine (AsB), arsenocholine (AsC), monomethylarsonic acid (MMA), dimethylarsonic acid (DMA)) in seafood were developed. The measurement of the tAs concentration was performed using...
