Surface Modification of Sisal Fibers for Enhanced Interface and Performance in Bio‐Based Polyurethane Composites

open access: yesPolymer Engineering &Science, EarlyView.
Schematic representation of the processing of sisal fibers (Agave sisalana) and their incorporation into bio‐based polyurethane composites. The fibers are extracted from the plant and subjected to surface modification via corona discharge and alkaline (NaOH) treatments.

Arbuscular mycorrhizal fungal inoculation increases the bioavailability of zinc and iron in wheat grain

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Bread wheat is an important crop that supplies calories and nutrients to the global population. Enhancing the concentrations and bioavailability of essential micronutrients in wheat is crucial for human nutrition, and we investigated whether arbuscular mycorrhizal (AM) fungi can contribute to the biofortification of wheat.

Molar incisor hypomineralisation: current knowledge and practice

open access: yesInternational Dental Journal, EarlyView., 2020
Background Molar incisor hypomineralisation (MIH) is a common developmental dental condition that presents in childhood. Areas of poorly formed enamel affect one or more first permanent molars and can cause opacities on the anterior teeth. MIH presents a variety of challenges for the dental team as well as functional and social impacts for affected ...

Effect on compressive strength of epoxy-modified mortar with further dry-curing [PDF]

open access: yes, 2015
The percentage of concrete porosity will affects the strength and performance of the concrete. It is believed that, with an additional curing, the porosity of the concrete becomes lower and the strength will increase.
