Influence of Polymer Processing on the Double Electrical Percolation Threshold in PLA/PCL/GNP Nanocomposites

open access: yesSensors, 2022
For the first time, the double electrical percolation threshold was obtained in polylactide (PLA)/polycaprolactone (PCL)/graphene nanoplatelet (GNP) composite systems, prepared by compression moulding and fused filament fabrication (FFF).

h-BN Modification Using Several Hydroxylation and Grafting Methods and Their Incorporation into a PMMA/PA6 Polymer Blend

open access: yesNanomaterials, 2022
Hexagonal boron nitride (h-BN) has recently gained much attention due to its high thermal conductivity and low electrical conductivity. In this study, we proposed to evaluate the impact of the modification of h-BN for use in a polymethylmethacrylate ...

Peculiar Morphologies Obtained for 80/20 PLA/PA11 Blend with Small Amounts of Fumed Silica

open access: yesNanomaterials, 2021
This work highlights the possibility of obtaining peculiar morphologies by adding fumed silica into 80/20 polylactic acid/polyamide11 (PLA/PA11) blends. Two kinds of fumed silica (A200 and trimethoxyoctylsilane modified R805 fumed silica) were dispersed (

THE INFLUENCE OF GENOTYPE, SOIL TILLAGE AND FERTILISATION ON CARBON SEQUESTRATION IN MAIZE [PDF]

open access: yesJournal of Applied Life Sciences and Environment, 2023
The increase in the concentration of greenhouse gases in the Earth’s atmosphere, especially that of CO2, is a major concern because it is the main source leading to global warming, and its impact on climate change is still widely studied.

Exploring Hybrid: A (hybrid) SIG to discuss hybrid conferences

open access: yesCHI Conference on Human Factors in Computing Systems Extended Abstracts, 2022
In this special interest group (SIG), we follow up on previous conversations around hybrid models for conferences, conducted in open sessions by the ACM Special Interest Group on Computer-Human Interaction (SIGCHI) Executive Committee (EC). The COVID-19 pandemic led to a sudden shift to virtual conferences; as we start to go back to in-person events ...
