Singularity links with exotic Stein fillings

, 2014
In a recent paper of Akhmedov, Etnyre, Mark and Smith, it was shown that there exist infinitely many contact Seifert fibered 3-manifolds each of which admits infinitely many exotic (homeomorphic but pairwise non-diffeomorphic) simply-connected Stein ...

In Situ Extrusion Processing of Treated and Untreated Pineapple Leaf Fibre-Reinforced PLA Composites for Improved Impact Performance

Journal of Manufacturing and Materials Processing
Material extrusion (MEX) 3D-printed parts are primarily used for prototyping rather than functional components due to lower mechanical strength. To address this limitation and promote sustainability, current work explores the reinforcement of plant-based

Study of mechanical and physical properties of pineapple leaf fiber and coffee husk filler reinforced polymer composite using response surface method

Polymer Testing
In the search for structural materials that are strong, lightweight, and cheap, pineapple leaf, which is rich in cellulose and relatively inexpensive, seems to have good potential reinforcement in yarn production.

Pineapple leaf fiber-based nonwovens as sustainable thermal insulation liner for distribution packaging

Future Foods
Pineapple leaf fiber (PALF)-based nonwovens were developed as a bio-based thermal insulation liner in fresh produce packaging. Effects of key parameters-fiber composition and bonding methods- were systematically investigated in relation to their physical
