•Kubo-Greenwood modelling of FDSOI MOSFETs down to deep cryogenic temperatures.•Single set of mobility parameters needed for drain current transfer characteristics description.•Neutral scattering ...mobility found at small gate length due to increased impact of neutral defects.•Closed-form analytical expression for Coulomb scattering has been developed.
A comprehensive Kubo-Greenwood modelling of FDSOI MOS devices is performed down to deep cryogenic temperatures. It is found that a single set of mobility parameters is only necessary to fit the capacitance and drain current transfer characteristics versus temperature for long channel devices. In contrast, in short channel transistors, the neutral scattering mobility component µN is found to decrease at small gate length due to the increased impact of neutral defects close to source/drain ends whatever the temperature. Moreover, a closed-form analytical expression for the Coulomb scattering has been developed, useful for device compact modelling.

•New PLLA-based copolymers with ABA architecture have been successfully synthesizied.•Copolymerization of PLLA leads to better mechanical and barrier properties.•The B aliphatic ...central block facilittes compostability process.
Novel poly(lactic acid)-based chain extended triblock copolymers have been successfully synthesized in melt. The new polymers are characterized by a triblock ABA architecture, where A, is poly(lactic acid) and B is an ad hoc synthesized random biobased aliphatic copolyester poly(propylene/neopentyl glycol succinate). PLLA homopolymer has been also prepared for the sake of comparison. The samples under study were deeply characterized from the molecular, thermal and structural point of view. Mechanical and barrier properties and compostability were also investigated, in order to assess the potentiality of these materials in food packaging applications. The results obtained show that copolymerization leads to better mechanical response and barrier properties with respect to poly(lactic) acid homopolymer. Moreover, the presence of the central B block in the main polymer chain facilitates the process of compostability.
Wheat flour replacement by rice flour is a key strategy in gluten-free batter production. Rice flour needs hydrocolloids to offset the development of the network of the mix. In this context, the aim ...of this work was to analyze the influence of chitosan (0–1 g/100 g of batter) addition on the microstructural, rheological and thermal properties of wheat:rice flours batters (100:0; 70:30, 30:70 and 0:100 (g/g)). Results showed that increasing replacement of wheat flour by rice one decreased the consistency (K) and the yield stress (τ0), and increased the flow behavior index (n) because of the absence or lower gluten content. However, the addition of only 0.25 g/100 g chitosan to rice flour formulation (0:100 (g/g)) increased its viscosity (from 371 to 1006 mPa s), exhibiting a rheological behavior similar to wheat flour formulation (100:0 (g/g) (1050 mPa s)). Chitosan enhanced consistency and structural agglomeration, and the interaction among ingredients, especially in batters with high content of rice flour (30:70 and 0:100 (g/g)). Lastly, chitosan incorporation did not significantly modify thermal properties, excepting in rice-flour batters (0:100 (g/g)), reducing Tm, ΔHm, and thus, increasing the bound water content (from 17 to 32 g/100 g).
•Chitosan (CH) increases viscosity in rice flour-based batters.•CH addition to rice flour based-batters improves structural agglomeration.•CH addition to wheat-rice flours batters do not influence their thermal behavior.

Taralli
is a bakery snack food, typical of the south of Italy, that has currently become very popular worldwide as a savory snack or bread substitute. However, few studies have focused on its ...physical and sensory characteristics. The present work aims to select sensory and instrumental information that is able to characterize
Taralli
with similar formulation and size. For sensory characterization purposes, conventional profiling was applied on samples from different producers. All samples were also subjected to physical analysis of appearance and textural proprieties. Three samples of the set, differing only in storage time, were evaluated to assess changes in sensory characteristics during this period and a discrimination test (triangle test) was also applied for this purpose. The test results confirmed that the sensory analysis allowed a description of the entire range of characteristics resulting from stimulation of senses by physicochemical properties of the food. This methodology was effective in evaluating the quality characteristics and identify differences between
Taralli
samples during different storage times. Instrumental tests were also applied to assess food quality. The results revealed that a combined approach allowed obtaining more information about the product characteristics and definition of quality standards. This study also suggests the use of physical parameters obtained by simple and rapid instrumental tools can support sensory analysis, especially for evaluations that are fatiguing, when decisions made with the sensory data are critical or to provide objective reference standards that are suitable for training purposes.
In the future hadron facility FAIR, the HESR ring will supply antiprotons in the momentum range 1.5-15 GeV c as projectiles to study charm, strangeness and a wide range of other Physics topics. For ...all these reactions it will be necessary to use internal targets and in particular, for the production of systems with double strangeness, a solid 12C target will be used. Inserting a solid target inside an antiproton ring creates two main problems: a large background on the detectors due to the overwhelming amount of annihilations and a strong depletion of the beam due to all the hadronic and Coulomb interactions of the antiprotons with the 12C nuclei. The width of the target plays a crucial role in minimizing these unwanted effects. Two wire-shaped prototypes have been already realized, starting from a thin diamond disk. The wire shape has been obtained by using a femto-edge laser. One prototype has been submitted to irradiation by protons of 1.5 MeV and to simultaneous Back-Scattering control to test the impurity level, the 12C density, the radiation hardness and possible phase modifications during irradiation. Both the prototypes have been submitted to Micro-Raman spectroscopy in order to scan the carbon phases along the width. The results show performances which satisfy the experimental requirements.
Research on dough rheology has been carried out for several years. Although many studies have considered the quality attributes of bread made from frozen dough, the use of additives and yeast in the ...formulation can mask the dough structure changes due to freezing. The objective of this study was to assess, by using texture profile analysis (TPA), Kieffer method and rheometer measurements, the influence of freezing and storage time on dough viscoelastic performance. As the aim of these experiments was only focused on the assessment of dough viscoelastic behaviour, no yeast or additives were incorporated to the samples’ composition. The obtained data showed that the longer the storage time at −18
°C, the lower the dough’s positive viscoelastic performance such as hardness, springiness, adhesiveness,
σ
max,
ε
H, storage and loss modulus. The observed changes of the non-fermented frozen dough rheological properties after thawing may be attributed to the damage on the gluten cross-linking, mainly produced by the ice crystallization.
A brief review of the double hypernuclei physics and state of the art of the todays available data is reported. The production of the prototype of diamond target is illustrated together with the ...tests to check its impurity level, the surface density, the radiation hardness and the phase modification. Finally the devised way to optimize the interaction between the bunch and the target, minimizing the detector damage, through the so-called “steering beam” technique is presented.
