A Density Functional Theory‐Genetic Algorithm Approach for the Structural Elucidation of Linear Diamantane Polyesters and their Nonlinear Optical Properties

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Diamondoid polyesters emit white light upon continuous infrared laser irradiation. The structures of the polyesters are microcrystalline as determined with solid‐state nuclear magnetic resonance spectroscopy combined with computational analyzes. We report a series of diamantane polyesters synthesized as head‐to‐head and side‐to‐side linear chain ...

Strain rate effect on the mechanical behaviour of a textile reinforced cement composite [PDF]

open access: yes, 2010
The static tensile behaviour of Textile Reinforced Cement Composites is known and can be modeled adequately. However, using these static material properties under dynamic loadings such as impact and seismic loadings, can cause over- or underestimation of

Microplastics in Agricultural Soil: Fate, Impacts, and Bioremediation by Earthworms

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
Microplastics enter the soil through various means, including the degradation of plastic film mulch, waste from cosmetics industries and municipalities, and the use of bioplastic seed coatings. These microplastics disrupt soil structure, microbial activity, enzyme function, and plant growth.

Film Blowing of Biobased Biodegradable Polyesters: Poly (Pentylene Adipate‐co‐Terephthalate) and Poly (Dodecylene Furanoate)

open access: yesMacromolecular Materials and Engineering, EarlyView.
Two novel biobased and biodegradable polyesters are explored as replacements for commercial PBAT and LLDPE in flexible film applications. Although some differences exist between these new materials and the commercial materials, nothing appears to disqualify these new materials as being acceptable as drop‐in replacements for flexible film applications ...

Harmfulness Score: A Data‐Driven Framework for Ranking Environmental Risks of Microplastics

open access: yesMacromolecular Rapid Communications, EarlyView.
Using machine learning and bibliometric sentiment analysis on over 100 000 abstracts, this study introduces the Harmfulness Score to rank environmental risks of microplastic polymers. Polystyrene and polyethylene emerge as top‐risk materials, supporting targeted regulation and evidence‐based policy recommendations.

Studio della propagazione della frattura in polibutene per tubi [PDF]

open access: yes, 2007
Il Polibutene-1 isotattico (i-PB1) è un materiale polimerico usato per la produzione di tubi per il trasporto di fluidi in pressione. In questo lavoro si sono studiati due tipi di i-PB1 prodotti da Basell che differiscono per grado di isotatticità.
