Eloy Peña-Asensio from QuantumGrain together with researcher Elisa Simó-Soler from the University of Valencia have published an article on planetary defense in the prestigious journal Acta Astronautica combining a scientific approach with a political-legal focus.

An important reentry event was recorded from Spain on Feb. 16th, 2021 starting at 5h57m36s TU by several stations of the Spanish Fireball and Meteorite Network (SPMN).

Formamide formation through the reaction of NH₂ with H₂CO, the main synthetic route in the gas-phase, has been computed on interstellar water ice surfaces, indicating that the ice stabilizes the intermediate rather than the product.

By accounting for the rate constants of the different elementary physico-chemical steps (diffusion, chemical reactions and desorption) we have identified that formation of acetaldehyde on water icy mantles is not so favourable as it is normally assumed.

Quantum chemical calculations help us investigating the adsorption of S-bearing species on a crystalline water ice model, highlighting the importance of dispersive forces in determining the strenght of their interaction.

We have found by experimental means that surfaces of chondritic meteorites catalyse Fischer-Tropsch (FT) reactions. By feeding the meteoritic samples with H2 and CO gases the typical FT products have been identified.

The structural, energetic, and vibrational properties of bulk and surfaces of Fe2NiP Schrebersite, a P-containing mineral found in meteorites, have been characterized computationally.

Ab initio molecular dynamics simulations show that the reaction of energy released by the H2 formation by H + H reaction is quickly absorbed in part by the ice surface, the remaining energy being used to promote H2 desorption.

Molecular simulations suggest that silicate nanoclusters with water either molecularly adsorbed or dissociated forming SiOH groups can be the responsible of the anomalous microwave emission (AME).

Solid-state computational simulations reveal that aggregation of nanosized proto-silicates can result with the formation of silicates that present physico-chemical features of those present in the diffuse interstellar medium.
