8 p, 1.6 MB Synthesis of urea on the surface of interstellar water ice clusters. A quantum chemical study / Perrero, Jessica (Universitat Autònoma de Barcelona. Departament de Química) ; Rimola, Albert (Universitat Autònoma de Barcelona. Departament de Química)
Urea is a prebiotic molecule that has been detected in few sources of the interstellar medium (ISM) and in Murchison meteorite. Being stable against ultraviolet radiation and high-energy electron bombardment, urea is expected to be present in interstellar ices. [...]

36 p, 3.3 MB Tracing the Primordial Chemical Life of Glycine : a Review from Quantum Chemical Simulations / Rimola, Albert (Universitat Autònoma de Barcelona. Departament de Química) ; Balucani, Nadia (Università di Perugia) ; Ceccarelli, Cecilia (Université Grenoble Alpes) ; Ugliengo, Piero (Università degli Studi di Torino)
Glycine (Gly), NHCHCOOH, is the simplest amino acid. Although it has not been directly detected in the interstellar gas-phase medium, it has been identified in comets and meteorites, and its synthesis in these environments has been simulated in terrestrial laboratory experiments. [...]

42 p, 1.9 MB Ab-initio computational study on Fe2NiP schreibersite : bulk and surface characterization / Pantaleone, Stefano (Università degli Studi di Torino. Dipartimento di Chimica) ; Corno, Marta (Università degli Studi di Torino. Dipartimento di Chimica) ; Rimola, Albert (Universitat Autònoma de Barcelona. Departament de Química) ; Balucani, Nadia (Università degli Studi di Perugia. Dipartimento di Chimica, Biologia e Biotecnologie) ; Ugliengo, Piero (Università degli Studi di Torino. Dipartimento di Chimica)
Phosphorus is ubiquitous in planet Earth and plays a fundamental role in all living systems. Finding a reasonable prebiotic source of phosphorus is not trivial, as common sources where it is present nowadays are in the form of phosphate minerals, which are rather insoluble and nonreactive materials, making it unavailable for ready incorporation in living organisms. [...]

15 p, 2.4 MB Prebiotic peptide bond formation through amino acid phosphorylation : insights from quantum chemical simulations / Martínez-Bachs, Berta (Universitat Autònoma de Barcelona. Departament de Química) ; Rimola, Albert (Universitat Autònoma de Barcelona. Departament de Química)
Condensation reactions between biomolecular building blocks are the main synthetic channels to build biopolymers. However, under highly diluted prebiotic conditions, condensations are thermodynamically hampered since they release water. [...]

44 p, 6.2 MB Role of mineral surfaces in prebiotic chemical evolution. In silico quantum mechanical studies / Rimola, Albert (Universitat Autònoma de Barcelona. Departament de Química) ; Sodupe Roure, Mariona (Universitat Autònoma de Barcelona. Departament de Química) ; Ugliengo, Piero (Università di Torino. Dipartimento di Chimica and NIS)
There is a consensus that the interaction of organic molecules with the surfaces of naturally-occurring minerals might have played a crucial role in chemical evolution and complexification in a prebiotic era. [...]

15 p, 650.6 KB Formation versus Hydrolysis of the Peptide Bond from a Quantum-mechanical Viewpoint : the Role of Mineral Surfaces and Implications for the Origin of Life / Rimola, Albert (Università di Torino. Dipartimento di Chimica IFM) ; Ugliengo, Piero (Università di Torino. Dipartimento di Chimica IFM) ; Sodupe Roure, Mariona (Universitat Autònoma de Barcelona. Departament de Química)
The condensation (polymerization by water elimination) of molecular Building blocks to yield the first active biopolymers (e. g. of amino acids to form peptides) during primitive Earth is an intriguing question that nowadays still remains open since these processes are thermodynamically disfavoured in highly dilute water solutions. [...]
