LM thesis proposal Supervisor: Giacomo Baldi In the last years, phase-change non-volatile memory devices have risen important attention for technological applications [1]. They are made by phase-change materials (PCMs), a class of functional materials that are reversibly and rapidly switched between amorphous and crystalline states by electrical pulses in a short timescale of a few …

Inelastic neutron scattering study of the origin of two-level systems in the atomic dynamics of strong glasses
LM thesis proposal Supervisors: Marco Zanatta & Giacomo Baldi At the macroscopic scale, an amorphous solid can be considered as an isotropic continuum and sound wave propagation is well described by the usual elasticity theory. However, the thermal properties at low temperatures (below 1 K) are heavily affected by the presence of two-level states whose …

Materials for laser ablation propulsion applications in space science
LM thesis proposal Supervisors: Antonio Miotello & Michele Orlandi When a short and intense laser pulse hits a material, extreme thermodynamic conditions are reached, resulting in the ejection of mass from the irradiated region. This phenomenon is known as laser ablation. Despite the ablated mass is in general small, it leaves the target surface with …

Solar Chemistry: photosynthesis and photocatalysis under concentrated sunlight
LM thesis proposal Supervisors: Michele Orlandi (michele.orlandi@unitn.it) & Antonio Miotello (antonio.miotello@unitn.it) Solar chemistry, where sunlight is employed to drive complex chemical reactions, can be used for a variety of applications, from the photosynthesis of value-added products such as pharmaceuticals, to solar wastewater treatments. In particular, solid-state materials designed as catalytic platforms capable of performing multiple …

Efficient implementation and validation of the Hamiltonian adaptive resolution (H-AdResS) simulations method
LM thesis proposal Supervisor: Raffaello Potestio (raffaello.potestio@unitn.it) One of the most challenging issues in molecular simulations is to match the gap in the broad range of length and time scales which characterises soft matter systems. One method which proved capable of reducing this gap is the Hamiltonian adaptive resolution simulation (H-AdResS) scheme [1], which enables …

Studies on solvation of biomolecules by UV Resonance Raman spectroscopy with synchrotron light
LM thesis proposal Supervisor: Ines Mancini (ines.mancini@unitn.it) Solvation of DNA and proteins in ionic liquids and deep eutectic solvents is able to stabilize and preserve their structures. Raman spectroscopy allows to provide molecular information on several kind of macromolecular systems through the investigation of their vibrational dynamics. Thanks to the resonance effect, multi-wavelength UV Resonance …

Carbon dioxide dissociation through anharmonic vibrational energy transfer
LM thesis proposal Supervisors: Raffaello Potestio (raffaello.potestio@unitn.it) & Paolo Tosi (paolo.tosi@unitn.it) CO2 dissociation is a topic of growing interest, also because of its possible applications to solve energetic and environmental problems. The CO2 –> CO + O reaction can be initiated by the electronic impact excitation of CO2 into a dissociative state, producing CO or …

Sequence-property relation of lattice polymers studied through the zeroes of the partition function
LM thesis proposal Supervisor: Raffaello Potestio (raffaello.potestio@unitn.it) In spite of their simplicity, lattice models of polymers are capable of providing a substantial qualitative and even quantitative insight in the physics of real polymeric macromolecules. A still open problem is the design of polymers featuring desired characteristics, that is, to define a sequence of monomers with …
