title: L’evoluzione tecnologica in Radioterapia: modulazione volumetrica del fascio ed Adaptavtive Radiation Therapy

description: Le innovazioni in radioterapia sono volte all’aumento del gradiente di dose tra neoplasia e tessuto sano attraverso un miglioramento sia dell’erogazione del fascio sia del controllo dell’errore. La più importante novità nel delivering è la modulazione volumetrica della intensità del fascio. La novità nel controllo dell’errore è rappresentata dalla Adaptative Radiation Therapy (ART), che prevede l’adattamento della distribuzione di dose ad un target mobile o deformabile, seguendo il movimento d’organo (IGRT) e la deformazione e cambio di volume di tumore e degli organi a rischio. La posizione iniziale del target viene riprodotta attraverso il movimento del lettino, il movimento elettronico del fascio, il movimento del braccio dell’acceleratore e la modifica dell’apertura del collimatore. La ART off line individua e corregge errori sistematici che possono avere origine in diverse fasi del processo e si propagano fino alla fine dello stesso, presentandosi in modo identico e ricorrente in ciascuna frazione attraverso il monitoraggio (IGRT) del posizionamento del paziente durante le prime frazioni, allo scopo di adattare i margini di trattamento e/o i piani di trattamento per le restanti sedutesu base individuale. La ART on line corregge errori random (di “esecuzione”), che possono variare di giorno in giorno, poiché si possono presentare in modo diverso per ciascuna frazione del trattamento, attraverso il monitoraggio (IGRT) del posizionamento del paziente durante tutte le frazioni per la misura e la correzione giornaliera degli errori di setup del paziente.

title: In vitro modelling of Streptococcus intermedius biofilm on titanium dental implants

description: Streptococcus intermedius is part of healthy oral flora; it is an opportunist pathogen in endogenous/systemic infections. This strain exhibits a tropism toward different typical biofilm diseases, e.g. periodontititis and peri-implantis. The aim of this study was to determine the biofilm colonization kinetics produced in vitro on titanium dental implants. Biofilm formation was evaluated by a PCR real-time protocol in order to determine the number of S. intermedius cells on the titanium implant surface. The in vitro model showed a striking fast progression of biofilm formation. Coating of salivary proteins on the implant surface peaked after 4 hours. The highest concentration of bacteria on the implant surface was at its highest after 4 hours as well. This indicates that the biofilm reached maturation within 5 hours.

title: Fast neutrons available through beam-target reactions driven by TW lasers

description: Laser accelerated deuterons with energy ranging from 0.1 to 2 MeV were exploited as drivers of the $7$Li(d,n)$8$Be nuclear fusion reaction. Deuterons were emitted by CD$2$ plasma produced with focused laser intensity of ~ 3x10$16$ W/cm$2$. Deuterons accelerated upstream the laser beam impinged on a LiF catcher target producing there D-Li neutrons with energy &gt; 13 MeV. Time-resolved signals of scintillation detectors were analysed with respect to the arrival time of fast neutrons at five scintillation detectors positioned around the target chamber. This analysis made it possible to determine energy of both the fusing deuterons and fusion neutrons. The energy spectrum of deuterons was also determined from the time-resolved charge density of ions derived from ion collector signals. Besides the neutrons produced through the 7Li(d,n)8Be fusion reaction, neutrons produced via the $2$H(d,n)$3$He reactions driven by the laser - CD$2$-plasma interaction were observed. The total dose of neutrons was determined employing high-sensitive bubble detectors (BD-PND). Since only a small fraction of generated fast deuterons were hitting the LiF catcher target, the maximum yield of neutrons from both the primary and secondary targets was ~ 3.5x10$8$ neutrons/shot, which gives a normalized yield of about 5.8x10$5$ neutrons/J. This value should still grow up when increasing the area of the catcher LiF target.

title: Metallic nanoparticles in thin foils for laser ion acceleration

description: Metallic nanoparticles have been obtained by 10$10$ W/cm$2$ Nd:YAg laser ablation in liquid at different irradiation conditions. The nanoparticles were based on Au, Ag, Ti and Cu with means size ranging between 10 nm and 100 nm at different concentrations. Nanoparticles were analyzed with optical absorption spectroscopy in the wavelength range 300-1000 nm. The resulting solutions have been deposited or embedded on different thin polymeric substrates (mylar, nuclepore, polyethylene). The laser irradiation of the prepared thin targets produces a backward plasma emission characterized by ion acceleration. Plasma was monitored in vacuum through ion collectors employed in time of flight configuration. The measurements reveal a significant ion acceleration enhancement of proton and carbon ions in the case of metal nanoparticles with respect to the case without, due to the increment of the laser energy deposition in the prepared targets for Surface Plasmon Resonant (SPR) absorption effect.

title: Study of Faraday cups for fast ion beams provided by a LIS source

description: Faraday cups are widely utilized to characterize ion and electrons beams. Owing to the secondary electron emission (SEE) induced by the collision of beams with collectors, wrong measurements could emerge from these detectors. To overcome this problem a polarized grid is utilized in front the cup collector at a negative voltage with respect to the collector. Unfortunately, the high voltage connection of the Faraday cups is hard to obtain. Then, in this work we want to study the secondary emission on different Al ion collector designs having tilted surfaces with respect to beam axis. Tests were performed using ion beams accelerated by a power supply up to 40 kV. The results by the modified collector surfaces were compared to the ones performed with a simple flat collector. The results we obtained point out that the secondary electron emission enhanced on incident beam energy and on the angle with respect to the normal direction of the surface. The ratio of the SEE to angle value results constant for the accelerating voltage and the possibility to design an ion collector able to reset the SEE seems not to be reached.

title: High Voltage System for the Generation of High Energy X-rays: synchronization and improvement

description: The x-ray (3 keV - 25 keV) are produced by high voltage discharge applied inside plasma source interaction chamber by focusing a laser beam. The control system is based on a high voltage power supply and an LC-inverter circuit with Thyratron, the generation of the trigger signal increasing the efficiency of the system. Analysis of the system, a possible layout with solid-state element and preliminary results of synchronization between high voltage discharge and Laser beam Nd-YAG are presented and discussed.

title: Realization and characterization of graphitic contacts on diamond by means of laser

description: This work deals with the realization and characterization of integrated graphitic contacts on diamond by means of laser irradiation (graphitization), in order to obtain good quality ohmic electrodes for nuclear radiation detectors to be used in high energy physics experiments. Unlike the conventional method used for the electrode production, which requires numerous steps and very well controlled environmental conditions, this alternative technique presents many advantages: the contacts are realized in air at room temperature in a single step. In this study, the characteristics of several graphitic structures realized on a diamond surface by changing the radiation-matter interaction parameters have been evaluated in order to define the best experimental conditions to create graphitic electrodes with low resistivity. The obtained results are promising: contacts perfectly adherent, with good charge collection properties, stable and resistant to ionizing radiation.

title: SiC detectors for fast diagnostic of high intensity laser-generated plasmas

description: SiC detectors, with 80 micron depletion layer, can be used with success in order to detect the radiations emitted from hot plasmas generated by fast and intense laser pulses. Due to the high energy gap with respect to the Si detectors, SiC doesn’t detect the high visible intensity radiation emitted from plasmas but it detects very well UV, X-rays, electrons and ions with high signal-to-noise ratio also at room temperature. It can be employed in two regimes: that of proportionality with the energy deposited in the sensitive volume and that of time-of-flight triggered by the laser shot. In both cases it permits to monitor photons, electrons and ions plasma emitted, giving information on their energy distribution. In particular the electron and ion spectra can be elaborated to permit the measurement of particle energy and of the equivalent plasma temperature. Some investigations performed at Physics Department of Messina University will be presented and discussed.

title: Comparative photoemission study between nanocrystalline diamond films and nanodiamond layers

description: Diamond films exhibit interesting properties, such as a wide bandgap (5.5 eV) and very low electron affinity which favours the electron photoemission. Diamond based cold photocathode is well known and demonstrated, due also to its chemical stability and mechanical robustness. In this work, a comparative study on photoemission of nanocrystalline diamond (NCD) film and nanodiamond (ND) layers obtained by microwave plasma enhanced chemical vapour deposition and pulsed spray technique, respectively, is presented and discussed evidencing advantages and drawbacks. The first technique permits to obtain thin NCD films at high deposition temperature (650-900 °C) with excellent homogeneity and adhesion; whereas the second one allows to deposit thin ND layer at a temperature of 120 °C with poor adhesion and low uniformity. Both NCD film and ND layers have been characterized by Raman spectroscopy, atomic force microscopy (AFM) and photoemission measurements.

title: Aluminium treatments to modify the surface wetting properties

description: Different techniques of surface treatments are employed to modify the physical properties of aluminum surfaces. Experimental data report measurements of liquid wetting ability in aluminum surfaces treated with different techniques: lapping, sanding, chemical etching, laser ablation, ion implantation and nanoparticle deposition. Surfaces can be modifies as a function of the different treatment parameters enhancing or reducing the wetting ability. Treatment duration, roughness and morphology play important role in determine the properties from hydrophobic to hydrophilic behavior.

title: Mechanical performance of single lap polymeric joints welded by a portable diode laser

description: The polymer laser welding can be successfully used to join two or more parts of plastic surfaces and it can be used in several fields, such as the biomaterials and microelectronics. Thermoplastic materials are welded by a localized energy input without the use of any organic solvents and formation of particulate.The employment of a portable diode laser can personalize the welding joint area and it let to draw the welding geometry, like a pen in a very easy and fast process. In this research, we studied single lap joints made by biomedical grade polyethylene (UHMWPE) pure and filled with carbon nanomaterials, necessary to make the polymer laser absorbent, added in amount of 0,2% in weight.The joints were irradiated by a diode laser operating at 970 nm (fundamental harmonic), in repetition rate of 10Hz, with a maximum pulse energy of 200 mJ and a laser spot of . 4 mm2 (no focusing lens were employed). The portable laser was employed to realize four types of welding geometries (points, continuous and discontinuous lines, cross lines) in the overlapped area. The joints were characterized by mechanical shear tests and hardness Shore D test and observed by a morphological analysis (optical microscopy). The results suggested that the welding strength depends not only on the welded area, but also on the continuity of the welded geometry and on the stress direction. The points welding exhibits the worse mechanical performance, while is the cross lines welding the best one among these investigated.

title: Search for possible effects of temperature and electron environment on the α-decay lifetime

description: We report on recent experimental and theoretical findings on possible effects of temperature, metal electron environment and pressure on the -decay constant. Contrary to recent claims, a possible screening effect of free electrons in a metal lattice at low temperature has to be ruled out on the basis of the experiment, while we find that effects induced by means of state-of-the-art compression techniques, although much smaller than previously speculated, might however be measurable. Considerable effects are expected in ultra-high-density stellar environments.

title: Quorum Sensing: correlation in the bacterial world

description: We show that, in particular experimental conditions, the time course of the radiant fluxes, measured from a bioluminescent emission of a Vibrio harveyi related strain, collapse after suitable rescaling onto the Gumbel distribution of extreme value theory. We argue that the activation times of the strain luminous emission follow the universal behavior described by this statistical law, in spite of the fact that no extremal process is known to occur.

title: High intense pulsed magnetic field for focusing ion beams and stressing biological materials

description: High intensity magnetic fields are employed to focus ion beams and they represent novel stress to study the behaviour of biological samples. In this work we present the realization of a magnetic pulser formed by a capacitor of 150 nF (50 kV) connected to ground by means of a pulsed high-voltage switch and solenoids for high current. The capacitor and the solenoid form a LC circuit oscillating at 210 kHz, 30 s, at a maximum repetition rate of 2 Hz. The solenoids were realized by a copper wire by 8 mm (11 rings) and 5 mm (20 rings) in diameter. The corresponding inductances were 3.6 and 16 H and the maximum currents generated at 50 kV of charging voltage of capacitor reached values up to 12 and 4.5 kA. The measurements determined a magnetic field at the centres of solenoid of 0.85 T for the less inductive solenoid and 0.5 T for the other one. The current diagnostic was performed by two systems: a self-integrating Rogowski coil and an integrator connected to a current transformer, both suitable for pulses longer than 1s.

title: Therapeutic use of moderate magnetostatic fields

description: A big debate is still dividing the scientific community about detrimental or beneficial effects of Static Magnetic Fields (SMFs) exposure on living matter. The heterogeneous findings are depending on the different experimental set up used, i.e., magnetic induction from 10$-7$ to more than 10 T, homogenous or inhomogeneous field, time of exposure and on the biological samples, i.e., from in vitro cultured cells to living organisms. In spite of the amount of publications providing medical evidence for the beneficial effects of SMF exposure can exert on living matter, a researcher must kept his obligatory scepticism due to the difficulties comparing different measurements, to the commercial interests and to poor scientific rigor. Nevertheless, their use has gained wide community acceptance for pain relief but not for more serious diseases, such as cancer. In this mini-review we will discuss on the studies on the therapeutic use of moderate magnetic induction SMFs, focusing on those produced by permanent magnets.
