The role of the interactions at the tungsten disulphide surface in the stability and enhanced thermal properties of nanofluids with application in solar thermal energy
(Multidisciplinary Digital Publishing Institute (MDPI), 2020)
Transition metal dichalcogenides (TMCs) exhibit unique properties that make them of interest for catalysis, sensing or energy storage applications. However, few studies have been performed into nanofluids based on TMCs for ...

Understanding the active sites of boron nitride for CWPO: An experimental and computational approach
(Elsevier, 2021)
Hexagonal boron nitride (h-BN) has been explored as a catalyst for degrading persistent organic pollutants in wastewater by Catalytic Wet Peroxide Oxidation (CWPO). Herein, the superior activity of the h-BN on the ...

Mixed monolayer of a nucleolipid and a phospholipid has improved properties for spectroelectrochemical sensing of complementary nucleobases
(Elsevier, 2021)
A mixed monolayer of 1,2-dipalmitoyl-sn-glycero-3-(cytidine diphosphate) nucleolipid (DG-CDP) and 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) was transferred from the air–water interface onto an gold (1 1 1) electrode ...

Citrate and Polyvinylpyrrolidone Stabilized Silver Nanoparticles as Selective Colorimetric Sensor for Aluminum (III) Ions in Real Water Samples
(MDPI, 2020)
The use of silver nanoparticles stabilized with citrate and polyvinylpyrrolidone as a sensor for aluminum ions determination is proposed in this paper. These non-functionalized and specific nanoparticles provide a highly ...

Multivalent Calixarene-Based Liposomes as Platforms for Gene and Drug Delivery
(MDPI, 2021-08)
The formation of calixarene-based liposomes was investigated, and the characterization of these nanostructures was carried out using several techniques. Four amphiphilic calixarenes were used. The length of the hydrophobic ...

Metalloenzyme-Inspired Ce-MOF Catalyst for Oxidative Halogenation Reactions
(American Chemical Society, 2021)
The structure of UiO-66(Ce) is formed by CeO2–x defective nanoclusters connected by terephthalate ligands. The initial presence of accessible Ce3+ sites in the as-synthesized UiO-66(Ce) has been determined by X-ray ...

Transient Sub-nanosecond Soft X-ray NEXAFS Spectroscopy on Organic Thin Films
(American Chemical Society, 2020)
We demonstrate visible pump soft X-ray probe near-edge X-ray absorption fine structure (NEXAFS) spectroscopy measurements at the carbon K edge on thin molecular films in the laboratory. This opens new opportunities through ...

Influence of the surfactant degree of oligomerization on the formation of cyclodextrin: surfactant inclusion complexes
(Elsevier, 2020)
Supramolecular complexation is an attractive strategy to modulate the performance of surfactants, e.g., by host-guest interactions. Here, we investigate the interaction of single-chained, di-, tri-, and tetrameric cationic ...

Formaldehyde tert-butyl hydrazone as a formyl anion equivalent: asymmetric addition to carbonyl compounds
(Royal Society of Chemistry, 2020)
The asymmetric 1,2-addition of formyl anion equivalents to carbonyl compounds is a powerful synthetic tool that ideally provide access to highly functionalizable a-hydroxy aldehydes in an enantioselective fashion. In ...

Π-Complexation for olefin/paraffin separation using aluminosilicates
(Elsevier, 2020)
The purification of the α-olefins though challenging, is mandatory step for their use in the chemical industry. Since adsorptive separation using zeolites is one of the most promising alternatives for olefin/paraffin ...
