Abstract (sommario):

This report summarizes the results in light quark spectroscopy achieved in last few years. The variety of experimental approaches, from kaon decays to fix target experiments and high statistics studies at e + e - colliders lead to radical progress in this field. Topics of interest include low energy pion pion scattering, scalars, higher excitations in meson spectra and exotics. The impact of these results on the understanding of nonperturbative QCD as well as further prospects are discussed.

Abstract (sommario):

Kiwifruit firmness was estimated by scattering 864 nm laser light through the fruit to exiting angles at 20 to 55° around the circumference of the fruit from the incident beam. The intensity of scattered light emitted from the fruit increased with decreasing firmness, especially at larger angles. The intensity changes were modelled using an inverse power law relationship between the intensity and a distance factor D = sin(θ / 2), where θ is the exiting angle. With increasing firmness the proportionality constant S increases and the power coefficient of D, – n, decreases. The logarithm of S gave the best linear regression results against stiffness and rupture force; two standard measures of fruit firmness, with R2 values of 83% and 79%, respectively.

Abstract (sommario):

Measured light scattering properties can be used to improve quantitative spectroscopic analyses of turbid samples. Instruments currently used to measure scattering coefficients are not optimised for portability. A hand-held, dual-wavelength instrument was developed and validated for rapid measurement of reduced scattering coefficients in tandem with near infrared spectra. Tissue simulating phantoms composed of Intralipid and dye were used to model clinically relevant optical properties. Time-dependent intensity profiles of diffusely reflected near infrared pulsed laser light were collected from phantoms and processed to estimate scattering coefficients. In turbid solutions, optical scattering was measured at 850 nm and 905 nm with coefficients of variation of 14.1% and 11.6% over a clinically-relevant reduced scattering coefficient range of 1 mm−1 to 6 mm−1. This dual-wavelength scattering measurement provides a practical method for measuring optical scattering. A 35% precision improvement in quantification of an absorbing dye is shown by incorporating the measured reduced scattering coefficients when processing NIR spectra. We discuss the new instrument, methods for estimating the scattering coefficient from the measured temporal profiles and, finally, how the reduced scattering coefficient is used to correct NIR measurements. Correction of near infrared spectra using optical scattering measurements offers one direction for improving practical non-invasive biomedical quantification techniques.

Abstract (sommario):

Molecular endofullerenes are supramolecular systems consisting of fullerene cages encapsulating small molecules. Although most early examples consist of encapsulated metal clusters, recently developed synthetic routes have provided endofullerenes with non-metallic guest molecules in high purity and macroscopic quantities. The encapsulated light molecule behaves as a confined quantum rotor, displaying rotational quantization as well as translational quantization, and a rich coupling between the translational and rotational degrees of freedom. Furthermore, many encapsulated molecules display spin isomerism. Spectroscopies such as inelastic neutron scattering, nuclear magnetic resonance and infrared spectroscopy may be used to obtain information on the quantized energy level structure and spin isomerism of the guest molecules. It is also possible to study the influence of the guest molecules on the cages, and to explore the communication between the guest molecules and the molecular environment outside the cage.

Abstract (sommario):

To construct robust calibrations of wood properties by near infrared spectroscopy, one must independently evaluate the spectral contributions of light absorption and light scattering. However, the light propagation in wooden cellular structures is difficult to interpret because these structures are complex, heterogeneous, and anisotropic. This study investigates the reduced scattering coefficients of softwood and hardwood (with ring-porous or diffuse-porous vessels) at 846 nm by time-resolved spectroscopy. It also evaluates the effect of wooden cellular structure and air-dry density on the light propagation. After determining the reduced scattering coefficients, we observed cross-sectional microscopic images of the wood samples. Eighty-five percent of the variation in the reduced scattering coefficients was explainable by the air-dry density, area ratio of the cell wall, and the median pore area. Monte Carlo simulations of the light propagation through wood revealed that most of the photon transport occurs in the cell-wall substance.

Abstract (sommario):

This paper introduces some applications of time-of-flight or time-resolved spectroscopy to cellulosic materials like wood. Time-of-flight or time-resolved spectroscopy uses short pulses of light illumination where a portion of the light is scattered but most of the light propagates through the sample. By using such technique, we could know that the light scattering contribution to near infrared spectra in wood is significant because it is a complex and highly scattering medium due to its cellulosic structure.

Abstract (sommario):

The energy efficiency of heterogeneous catalytic processes may be improved by using mid-infrared light to excite gas-phase reactants during the reaction, since vibrational excitation of molecules has been shown to increase their reactivity at the gas-catalyst interface. A primary challenge for such light-enabled catalysis is the need to ensure close coupling between light-excited molecules and the catalyst throughout the reactor. Thus, it is imperative to understand how to couple infrared light efficiently to molecules near and inside catalytic material. Heterogenous catalysts are often nanoscale metal particles supported on high surface area, porous oxide materials and exhibit feature sizes across multiple scattering regimes with respect to the mid-infrared wavelength. These complex powders make a direct measurement of the scattering properties challenging. Here, we demonstrate that a combination of directional hemispherical measurements along with the in-line transmission measurement allow for a direct measurement of the scattered light signal. We implement this technique to study the scattering behavior of the catalytic support material γ-Al2O3 (with and without metal loading) between 1040 and 1220 cm−1. We first study how both the mean grain size affects the scattering behavior by comparing three different mean grain sizes spanning three orders of magnitude (2, 40, and 900 µm). Furthermore, we study how the addition of metal catalyst nanoparticles, Ru, or Cu, to the support material impacts the light scattering behavior of the powder. We find that the 40 µm grain size scatters the most (up to 97% at 1220 cm−1) and that the addition of metal nanoparticles narrows the scattering angle but does not decrease the scattering efficiency. The strong scattering of the 40 µm grains makes them the most ideal support material of those studied for the given spectrum because of their ability to distribute light within the reactor. Finally, we estimate that less than 100 mW of laser power is needed to cause significant excitation for testing mid-infrared catalysis in a Harrick Praying Mantis diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) reactor, a magnitude easily available using commercial mid-infrared lasers. Our work also provides a mid-infrared foundation for a wide range of studies of light-enabled catalysis and can be extended to other wavelengths of light or to study the scattering behavior of other complex powders in other fields, including ceramics, biomaterials, and geology.
