Environmental Risk Assessment and Anti‐Corrosion Efficacy of Safe‐by‐Design Nitrite‐Based Nanomaterials for Maritime Applications

open access: yesNano Select, EarlyView.
The environmental behavior and impact of anti‐corrosion nanoadditives, ZnAl‐NO2 and MgAl‐NO2 layered double hydroxides (LDH), are assessed under marine conditions. These nanomaterials show instability in water but exhibit no or low toxicity to most tested marine species.

Mechanical Performance Under Compressive Load of Carboxylated Nitrile Rubber and Kraft Lignin Composites

open access: yesPolymer Composites, EarlyView.
Lignin dispersion in carboxylated nitrile rubber (XNBR) is enhanced at 7% carboxylic acid, significantly improving the composite's compressive mechanical performance for sealing applications. ABSTRACT Lignin is a promising biobased material that enhances the sustainability of rubber composites as a reinforcing filler.

Influence of Hornification Treatment and Fiber Length on the Performance of Recycled Polypropylene Composites

open access: yesPolymer Composites, EarlyView.
Study of the influence of hornification treatment and jute and mallow fiber length on the physical, thermal, and mechanical properties of recycled polypropylene (PP) composites. ABSTRACT The growing accumulation of plastic waste has driven its reuse in the development of new composites, with natural fibers emerging as promising reinforcements. However,

Agricultural Price Seasonality and Market Failure: Examining the Net Seller Household and the Net Benefit Ratio Definition [PDF]

open access: yes
On the basis of a household typology distinguishing between net sellers, net buyers and self sufficient, the Net Benefit Ratio (NBR), defined by Deaton (1989), is used to approximate households' first order welfare variations when price change.

Order Independence and Rationalizability [PDF]

open access: yes, 2005
Two natural strategy elimination procedures have been studied for strategic games. The first one involves the notion of (strict, weak, etc) dominance and the second the notion of rationalizability.
