This work is an extension of the time-resolved poro-elasto-plastic MohrCoulomb model by Fokker et al to include a more realistic constitutive model. Experiments on Slochteren sandstone revealed that the inelastic deformation contributes significantly in compressive deformation almost in all stages of loading and instigated the development of a...

To ensure a circular economy for plastics, insights in the environmental impacts of recycling and optimal recycling choices for specific plastic polymers are crucial. This was obtained by determining the environmental performance of 10 selected recycling technologies with varying TRL levels, using the chemical properties of the top 25 produced...

Increasing the stream of recycled plastic necessitates an approach beyond the traditional recycling via melting and re-extrusion. Various chemical recycling processes have great potential to enhance recycling rates. In this Review, a summary of the various chemical recycling routes and assessment via life-cycle analysis is complemented by an...

Crack closure effects during fatigue crack growth have been studied by many researchers with the finite element method, but appears difficult to accurately predict. Although quantification of crack closure may be a bridge too far, finite element models may help explaining observations from tests and give insight into trends. This paper studies...

Plastics (bulk, coatings, and glues), like many other commodities, including metal, wood, glass, and ceramics, are of essential importance to the wellbeing of today’s society. This will not be any different in the decades to come. We expect plastics to remain important due to their unique properties and the possibilities for mass production...

Two basic procedures are currently available to determine the critical condition of a flawed structure, at which unstable crack extension may occur. The first method based on elastic-plastic fracture mechanics is accurate but requires a time consuming elastic-plastic finite element analysis. The second method estimates the critical condition...

The hydroplasticization of coatings of acrylic copolymers with different amounts of methacrylic acid (MAA) was investigated to clarify the role of carboxylic acid functionalities on the change in polymer mobility due to water uptake. The coating T g as a function of water uptake was studied using dynamic mechanical analysis. The T g 's decreased...

Types of plastic waste in different aquatic environments were assessed to obtain a global framework of plastic waste transport and accumulation, relevant for plastic pollution mitigation strategies in aquatic environments. Packaging and consumer products were the most encountered product categories in rivers, while fishery items dominated in the...

BACKGROUND: In the present study, the rate of dermal transfer of pesticides to agricultural workers occurring via contact with sprayed hard surfaces was investigated. Cotton gloves were used as dosimeters to collect residues from hard surfaces contaminated by pesticides in greenhouses. Dosimeters, either dry or moistened, were in contact with...

GARField 1H NMR relaxometry experiments were done to study the drying process of two latices with different polymer Tg and to elucidate water mobility behavior during this process. It was found that the hard type latex, with a polymer Tg above room temperature, dries faster than the soft type latex, with a polymer Tg below room temperature....

Adverse outcome pathways (AOPs) are a recent toxicological construct that connects, in a formalized, transparent and quality-controlled way, mechanistic information to apical endpoints for regulatory purposes. AOP links a molecular initiating event (MIE) to the adverse outcome (AO) via key events (KE), in a way specified by key event...

In the small scale LNG infrastructure, composite materials are scarcely employed. Potentially, cost effective solutions for LNG applications could be developed thanks to the advantages of composite materials over metals such as weight savings, design flexibility and recyclability. The research presented in this paper focuses on the mechanical...

Perovskite solar cells (PSCs) have recently attracted the attention of the scientific community because of the rapid advances in their development. Most of the state-of-the-art devices contain mesoporous titanium dioxide (TiO2) as an electron transport layer. The drawback of such TiO2 layers is that it often needs high temperature sintering at...

This paper describes a combination of photonic annealing and compression rolling to improve the conductive properties of printed binder-based graphene inks. High-density light pulses result in temperatures up to 500 °C that along with a decrease of resistivity lead to layer expansion. The structural integrity of the printed layers is restored...

Localised buckles can occur in crasheswhen compressive stresses are dominant. However, due to their local appearance, they might be overlooked by a finite element analysis, meaning that local failure due to bucklingwill not be predicted. This could, for example, be catastrophic in the case of the crushing of a fuel tank or the impact on a ship...
