Modeling termination kinetics of non-stationary free-radical polymerizations
No full textPulsed-laser induced polymerization is modeled via an approach presented in a previous paper. An equation for the time dependence of free-radical concentration is derived. It is shown that the termination rate coefficient may vary significantly as a function of time after applying the laser pulse despite of the fact that the change in monomer concentration during one experiment is negligible. For the limiting case of t ≫ c-1 (kpM)-1, where c is a dimensionless chain-transfer constant, kp the propagation rate coefficient and M the monomer concentration, an analytical expression for kt is derived. It is also shown that time-resolved single pulsed-laser polymerization (SP-PLP) experiments can yield the parameters that allow the modeling of kt in quasi-stationary polymerization. The influence of inhibitors is also considered. The conditions are analyzed under which M (t) curves recorded at different extents of laser-induced photo-initiator decomposition intersect. It is shown that such type of behavior is associated with chain-length dependence of kt
Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
No full textThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region

Sustainability and Circularity: New Material Scenarios for Product Design
No full textThe concept of sustainability is a continually evolving threshold in step with technology and the ability it provides for understanding the environment. Various disciplines have always contributed by bringing essential concepts and tools to approach the growing complexity of the design project and its continuous dialogue with the environment.
The world we live in, now devastated in all its parts by depletion and pollution related to the choices of an unsustainable economy, needs adequate design solutions consistent with the concept of sustainability and circularity. Although it has been talked about for a long time, however, significant research and contributions are still needed on new material solutions that make new products possible and establish new design methods and practices.
It has been estimated that 80% of the environmental impact of a product or service is determined in the design phase, which is why product design has a great responsibility and must try to guide the transition towards a more sustainable and circular economy.
This Special Issue aims to bring together research on the development of materials and processes that can foster the development of innovative products that can promote a circular economy. It includes research on rethought and updated traditional materials; interactive, connected and smart materials; self-produced materials using alternative resources such as waste and scrap; upcycling processes, living biological materials or those that have lived, capable of self-generating and growing.
The contributions will highlight these different possible ways of closing the cycles through a virtuous integration between product design, material science and economy. The concepts of sustainability and circularity can be interpreted both in an environmental and a social sense.
We, therefore, welcome articles on recent or ongoing research in the field of materials for design that highlight valid alternatives to the current unsustainable and linear solutions
C*-algebras have a quantitative version of Pełczyński's property (V)
No full textsummary:A Banach space has Pełczyński's property (V) if for every Banach space every unconditionally converging operator is weakly compact. H. Pfitzner proved that -algebras have Pełczyński's property (V). In the preprint (Krulišová, (2015)) the author explores possible quantifications of the property (V) and shows that spaces for a compact Hausdorff space enjoy a quantitative version of the property (V). In this paper we generalize this result by quantifying Pfitzner's theorem. Moreover, we prove that in dual Banach spaces a quantitative version of the property (V) implies a quantitative version of the Grothendieck property
