Significance Silica particles with a population of nearly free silanols damage cellular membranes and initiate inflammatory reactions. Nearly are found on the surface both fractured quartz amorphous silica particles, their occurrence initiates toxicity silica, thus revisiting ancient paradigm whereby crystallinity is critical for toxicity. This finding resolves lingering questions about origin variability particles. The discovery biological activity opens perspectives prevention silicosis...
Water is a molecule always present in the reaction environment photocatalytic and biomedical applications of TiO2 better understanding its interaction with surface nanoparticles crucial to develop materials improved performance. In this contribution, we first studied nature structure exposed facets three commercial samples (i.e., P25, SX001, PC105) by electron microscopy IR spectroscopy adsorbed CO. The morphological information was then correlated water adsorption properties, investigated...
Cholesterol, the essential building block of cellular membranes, has proven to be a useful tool for increasing biocompatibility and bioavailability drug delivery systems in cancer treatment. Resveratrol, natural polyphenolic compound with promising anticancer properties, faces significant limitations due its low solubility bioavailability, hindering clinical utility. Therefore, present study, we aimed design cholesterol-functionalized cyclodextrin nanosponges (Chol-NSs) tunable cholesterol...
HCN in the gas form is considered as a primary nitrogen source for synthesis of prebiotic molecules extraterrestrial environments. Nevertheless, research mainly focused on reactivity and its derivatives aqueous systems, often using external high-energy supply cosmic rays or high energy photons. Very few studies have been devoted to chemistry phase at gas/solid interphase, although they represent more common scenarios outer space. In this paper we report about highly pure 150-300 K range...
Understanding the interaction between hydrogen cyanide (HCN) and silicate surfaces is crucial for elucidating prebiotic processes occurring on interstellar grain cores as well in cometary meteoritic matrices. In this study, we characterized adsorption features of HCN crystalline forsterite (Mg2SiO4) surfaces, one most abundant cosmic silicates, by combining experimental infrared spectra at low temperatures (100–150 K) with periodic DFT simulations. Results showed coexistence both molecular...
MoS2/TiO2-based nanostructures have attracted extensive attention due to their high performance in many fields, including photocatalysis. In this contribution, MoS2 were prepared via an situ bottom-up approach at the surface of shape-controlled TiO2 nanoparticles (TiO2 nanosheets and bipyramids). Furthermore, a multi-technique by combining electron microscopy spectroscopic methods was employed. More detail, morphology/structure vibrational/optical properties slabs on anatase bipyramidal...
The photoreduction of the Mo6+/SiO2 system with CO was investigated in situ, employing a recently developed experimental setup allowing for acquisition transmission FT-IR spectra under simultaneous UV irradiation. Carbon monoxide, besides acting as reducing agent such processes, is also useful probe molecule able to detect coordinatively unsaturated sites exposed on surface. unprecedented quality spectroscopic data, obtained function reduction time, allowed us better rationalize different...

Asteroids are the most ancient bodies of a planetary system, mostly formed during accretion protoplanetary disk. They can be made either rocky and metallic materials, they sources important species which fundamental for emergence life on planets. In our history, heavy late bombardment (4.0−3.8 Gya ago), large quantity meteorites (the asteroids that impact planet) fall onto earth crust, bringing several interstellar complex organic molecules, as well other (like phosphorus),...
