Bio‐Based Polyurethanes: Mechanical Performance, Structure–Property Relationships, and Future Directions

Journal of Polymer Science, EarlyView.
This review examines bio‐based polyurethanes from renewable feedstocks, focusing on structure‐property relationships governing mechanical performance. It analyzes reinforcement strategies, benchmarks against petrochemical counterparts, and explores future directions, including non‐isocyanate routes and circular economy integration for sustainable high ...

Control failure risk, resistance and enzymatic activity of neurotoxic insecticides in Brazilian populations of Leucoptera coffeella (Lepidoptera: Lyonetiidae)

Pest Management Science, EarlyView.
Bioassays of 36 Leucoptera coffeella populations revealed resistance to neurotoxic insecticides, control failures of ≤62.9% and enzyme activity variation, with particularly high GST and low AChE levels. Abstract Background Leucoptera coffeella is a key pest of coffee crops in Brazil, causing significant damage by mining coffee leaves.

On the Origins of Out‐of‐Plane Auxetic Response in Paper

physica status solidi (b), EarlyView.
Paper can be auxetic! Paper can exhibit a range of out‐of‐plane Poisson's ratio (PR) values. Examining handsheets made from hardwood (HW) and softwood (SW) fibers, of a variety of weights (1, 3, or 5 g) and refining degrees (none, R, or R+), showed that the sign and magnitude of PR can be finely controlled by modifying network parameters.

Leveraging Life Cycle Assessment for Informing Packaging Eco‐Design and Eco‐Modulation

Sustainable Development, EarlyView.
ABSTRACT Eco‐modulation is designed to promote the adoption of eco‐design. However, in practice, its application is mostly concentrated on end‐of‐life (EoL) optimization. This study addresses the gap by proposing a framework to assess product–packaging systems as integrated units throughout the full life cycle.

Variables Affecting Impregnation during Kraft Pulping [PDF]

, 1982
Introduction The purpose of this report was twofold. First, a pulping aid was evaluated for its effects on pulp properties. Then, the pulping aid was used in conjunction with a reduction in the times to temperature for several cooks, to see if the ...

Evaluation Methodology, Numerical Verification and Retrofilling Procedure for Power Transformers to Ensure K‐Class Flame Retardancy and Environmentally Friendly

High Voltage, EarlyView.
ABSTRACT With increasing demands for fire safety and environmental friendliness, retrofilling transformers with alternative insulating liquids has become a growing trend. However, retrofilling power transformers remains uncertain, as more residual mineral oil compromises K‐class flame retardancy, and its impact on environmental performance has yet to ...

Drivers of phenological transitions in the seedling life stage

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant functional ecology research has primarily focused on juvenile and adult plants even though regeneration from seed can be the most consequential life‐history bottleneck with cascading influence on later stages of growth and reproduction.

From Tobacco to Ultraprocessed Food: How Industry Engineering Fuels the Epidemic of Preventable Disease

The Milbank Quarterly, EarlyView.
Policy Points Ultraprocessed foods (UPFs) are engineered to heighten reward and accelerate delivery of reinforcing ingredients, driving compulsive consumption and disrupting appetite regulation. This is a growing challenge for health policy. UPFs share key engineering strategies adopted from the tobacco industry, such as dose optimization and hedonic ...

A Research on the Strength of Kraft Paper

JAPAN TAPPI JOURNAL, 1966
A lot of researches have been announced about the relation between the tension given to sheet and the strength of accomplished paper in the process of drying sheet. These researches, however, every of them, are described that by adding a constant tension or threegraded tension to sheet in the process of drying it, it should be dried and, then analized.
