Study of biodegradable poly(butylene succinate‐co‐adipate) (PBSA) maleation: Analysis of grafting, thermal, and rheological behaviour

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Maleation of poly(butylene succinate‐co‐adipate) (PBSA): Effect of the initiator concentration on the grafting percentage. Abstract Herein, the effects of varied concentrations of an organic peroxide and maleic anhydride (MA) on the grafting percentage as well as the amount of gel content, rheological, and thermal properties of MA‐grafted‐poly(butylene

Study on the effect of co‐plasticization of post‐industrial starch for high‐impact thermoplastic starch development

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
High‐impact thermoplastic starch blends through the co‐plasticization methodology. Abstract This study analyzed the effect of employing plasticized or co‐plasticized post‐industrial starch in developing PBAT‐based thermoplastic starch (TPS) blends. In this work, the post‐industrial wheat starch was co‐plasticized with glycerol‐urea, glycerol‐citric ...

Form and load transfer aspects of foundation systems: Case‐based implementation and adaptation for buildings

open access: yesDeep Underground Science and Engineering, EarlyView.
Upon conceptualization of structural behavior, foundations in terms of their form are divided into linear (1D), planar (2D), and volumetric (3D). Regarding the load transfer mechanisms, linear foundation systems are considered vector‐acting, planar foundations are divided into section and surface‐acting, and volumetric ones are recognized as block ...

Geological and geotechnical challenges on the Great Dyke of Zimbabwe and their impact on hardrock pillar design

open access: yesDeep Underground Science and Engineering, EarlyView.
The Great Dyke of Zimbabwe is notable for its rich platinum group metal deposits but poses significant geological and geotechnical challenges due to its complex rock types and structural features. Traditional pillar design methods are insufficient for addressing these complexities; the study suggests incorporating advanced techniques such as machine ...
