Development of Cellulosic Bioplastic‐Based Biocomposites for Biodegradable Packaging Applications: Effect of High Acetyl Content and High Filler Loading

open access: yesPolymer Engineering &Science, EarlyView.
Schematic representation of the development of cellulosic bioplastic‐based biocomposites via reactive extrusion and injection molding, demonstrating improved oxygen and water vapor barrier properties for biodegradable packaging applications. ABSTRACT Cellulosic bioplastics have attained significant interest because of their biodegradability and ...

Improving Welding Behavior of ETPU Bead Foams by Surface Modification with Plasticizers

open access: yesJournal of Polymer Science, EarlyView.
Tributyl citrate (TBC) and stearic acid (SA) modify ETPU beads through different diffusion mechanisms. TBC diffuses the bead structure directly after coating, whereas SA remains on the surface until melting and subsequent diffusion during heating. The resulting plasticization improves bead fusion, allowing RF processing at reduced temperature and ...

Influence of calcination temperature on the durability of metakaolin concrete and limitations of conventional testing methods

open access: yesStructural Concrete, EarlyView.
Abstract Incorporating metakaolin (MK) as a partial cement replacement offers a viable pathway to reduce carbon emissions while improving concrete performance. However, its durability behavior remains inconsistent, and the applicability of durability test methods to MK‐based concrete is not well established.

Hydrothermal syntheses of zeolite N from kaolin [PDF]

open access: yes, 2012
Zeolite N, an EDI type framework structure with ideal chemical formula K12Al10Si10O40Cl2•5H2O, was produced from kaolin between 100oC and 200oC in a continuously stirred reactor using potassic and potassic+sodic liquors containing a range of anions ...

High temperature fracture behavior and damage evolution of recycled aggregate concrete produced from metakaolin modified parent concrete

open access: yesStructural Concrete, EarlyView.
Abstract The increasing use of recycled aggregate concrete (RAC) offers significant environmental benefits by reducing construction and demolition waste; however, its fracture performance and damage evolution under elevated temperatures remain insufficiently understood, particularly when recycled aggregates are derived from metakaolin modified parent ...

Effect of kaolin particle size and loading on the characteristics of kaolin ceramic support prepared via phase inversion technique

open access: yesJournal of Asian Ceramic Societies, 2016
In this study, low cost ceramic supports were prepared from kaolin via phase inversion technique with two kaolin particle sizes, which are 0.04–0.6 μm (denoted as type A) and 10–15 μm (denoted as type B), at different kaolin contents ranging from 14 to ...

Evolutionary Mechanisms of Coagulation Factors in Cetaceans During Aquatic Adaptation

open access: yesIntegrative Zoology, EarlyView.
Compared with Bos taurus, T. truncatus showed shorter prothrombin time and thrombin time but prolonged activated partial thromboplastin time, indicating pathway‐specific remodeling of coagulation. Evolutionary analyses identified 18 positively selected genes and accelerated F11 evolution, while functional assays revealed increased coagulation factor ...

Post‐Occlusion Application of Skin Protective Creams Does Not Affect Occlusion‐Induced Barrier Changes: A Randomized Controlled Experimental Study

open access: yesContact Dermatitis, EarlyView.
Post‐occlusion application of protective creams did not consistently reduce occlusion‐induced skin barrier impairment after glove use. Protective efficacy probably depends on formulation and timing, with only immediate pre‐irritant application showing a significant reduction in SLS‐induced barrier disruption.
