An antiviral filament and an antiviral three-dimensionally printed component including an antiviral polymer including a base polymer, and an antiviral agent incorporated in the base polymer, wherein the antiviral agent exhibits a phase transition temperature of 200 degrees Centigrade or greater. A method of fabricating a three-dimensional component including feeding an antiviral filament into an extrusion nozzle, the antiviral filament comprising an antiviral polymer; applying heat and pressure to the antiviral filament to melt the antiviral filament in the extrusion nozzle; extruding the antiviral filament from the extrusion nozzle; depositing the extruded antiviral filament into layers; and forming a three-dimensional component from the layers of extruded antiviral filament.

The present invention relates to compounds which can be used to control plant development. Indeed, the present invention discloses a new class of pyrabactin analogues which have a physiological effect onfor exampleseed germination, and/or stomatal closure, and/or have developmental effects on root and shoot development and organogenesis. Hence, the latter compounds can be used to control plant development such asfor exampleincreasing the tolerance of plants to drought stress or to control physiological phenomena such as pre-harvest sprouting, tolerance to pathogens etc.
