In spite of the advent of extremely large telescopes in the UV/optical/NIR range, the current generation of 8-10m facilities is likely to remain competitive at ground-UV wavelengths for the foreseeable future. The Cassegrain U-Band Efficient Spectrog

Probing Reactivity with External Forces: The Case of Nitroacetamides in Water

Autor: Giovanni La Penna, Fabrizio Machetti

Publikováno v: Molecules, Vol 29, Iss 1, p 9 (2023)

Many computational methods have been applied to interpret and predict changes in reactivity by slight modifications of a given molecular scaffold. We describe a novel and simple method based on approximate density-functional theory of valence electro

Multi-scale theoretical approach to X-ray absorption spectra in disordered systems: an application to the study of Zn(II) in water

Autor: Stellato, Francesco, Calandra, Matteo, D'Acapito, Francesco, De Santis, Emiliano, La Penna, Giovanni, Rossi, Giancarlo, Morante, Silvia

We develop a multi-scale theoretical approach aimed at calculating from first principles X-ray absorption spectra of liquid solutions and disordered systems. We test the method by considering the paradigmatic case of Zn(II) in water which, besides be
