When ruthenia met titania: achieving extraordinary catalytic activity at low temperature by nanostructuring of oxides
(Royal Society of Chemistry, 2015)
Nanostructured RuOx/TiO2(110) catalysts have a remarkable catalytic activity for CO oxidation at temperatures in the range of 350-375 K. On the other hand, the RuO2(110) surface has no activity. The state-of-the-art DFT ...

Microheterogeneous catalysis
(MDPI, 2010)
The catalytic effect of micelles, polymers (such as DNA, polypeptides) and nanoparticles, saturable receptors (cyclodextrins and calixarenes) and more complex systems (mixing some of the above mentioned catalysts) have ...

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 ...

Electrochemical STM study of the adsorption of adenine on Au(111) electrodes
(Elsevier, 2013)
An electrochemical scanning tunneling microscopy (EC-STM) study of the adsorption of adenine on Au(111) electrodes was undertaken in the pH range between 1 and 7, aiming at achieving a deeper knowledge on the structure and ...

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 ...

Electromembrane Extraction Based on Biodegradable Materials: Biopolymers as Sustainable Alternatives to Plastics
(Elsevier, 2023)
Green and environmentally friendly approaches are increasingly necessary when developing new analytical methodologies. Electromembrane extraction (EME) has contributed to this by offering new alternatives to the traditional ...

Impact of the number of fitted Debye-Waller factors on EXAFS fitting
(IOP Publishing, 2013)
EXAFS fit applied to asymmetric systems may imply the fit of parameters for many scattering paths. We illustrate on some examples how fitting too many independent DWs may lead to incorrect distances and mask some structural ...

Exploring the potential as molecular quantum-dot cellular automata of a mixed-valence Ru2 complex deposited on Au(111) surface
(Royal Society of Chemistry, 2023-03-21)
A key requirement for the implementation of molecular quantum dot cellular automata (mQCA) is the ordered attachment of molecules on surfaces. In this work we explore by means of stateof- the art quantum chemistry ...

Visible Light-Driven H2 Production over Highly Dispersed Ruthenia on Rutile TiO2 Nanorods
(American Chemical Society, 2016)
The immobilization of miniscule quantities of RuO2 (∼0.1%) onto one-dimensional (1D) TiO2 nanorods (NRs) allows H2 evolution from water under visible light irradiation. Rod-like rutile TiO2 structures, exposing preferentially ...

Comprehensive Experimental and Theoretical Study of the CO + NO Reaction Catalyzed by Au/Ni Nanoparticles
(American Chemical Society, 2019)
The catalytic and structural properties of five different nanoparticle catalysts with varying Au/Ni composition were studied by six different methods, including in situ X-ray absorption spectroscopy and density functional ...
