Formation of hollow silver nanoparticles under irradiation with ultrashort laser pulses.

We have studied the formation of cavities in spherical silver nanoparticles embedded in silica, irradiated with fs laser pulses that produce an intense electronic excitation. Experimentally determined aspect ratio, i.e.

Increased Absorption of Thyroxine in a Murine Model of Hypothyroidism Using Water/CO Nanobubbles.

Thyroxine (T4) is a drug extensively utilized for the treatment of hypothyroidism. However, the oral absorption of T4 presents certain limitations. This research investigates the efficacy of CO nanobubbles in water as a potential oral carrier for T4 administration to C57BL/6 hypothyroid mice.

Characterization and Performance Enhancement of Cement-Based Thermoelectric Materials.

Thermoelectric materials enable the direct conversion of thermal to electrical energy. One application of this is ambient heat energy harvesting where relatively stable temperature gradients existing between the inside and outside of a building could be utilized to produce electricity. Buildings can thus change from energy consumers to energy generators.

Inelastic scattering of electrons in water from first principles: cross sections and inelastic mean free path for use in Monte Carlo track-structure simulations of biological damage.

Modelling the inelastic scattering of electrons in water is fundamental, given their crucial role in biological damage. In Monte Carlo track-structure (MC-TS) codes used to assess biological damage, the energy loss function (ELF), from which cross sections are extracted, is derived from different semi-empirical optical models. Only recently have first results for the ELF and cross sections in water become available.

Efficient ab initio calculation of electronic stopping in disordered systems via geometry pre-sampling: Application to liquid water.

Knowledge of the electronic stopping curve for swift ions, S(v), particularly around the Bragg peak, is important for understanding radiation damage. Experimentally, however, the determination of such a feature for light ions is very challenging, especially in disordered systems such as liquid water and biological tissue. Recent developments in real-time time-dependent density functional theory (rt-TDDFT) have enabled the calculation of S(v) along nm-sized trajectories.
