High-Impact Polystyrene Reinforced with Reduced Graphene Oxide as a Filament for Fused Filament Fabrication 3D Printing.

Graphene and its derivatives, such as graphene oxide (GO) or reduced graphene oxide (rGO), due to their properties, have been enjoying great interest for over two decades, particularly in the context of additive manufacturing (AM) applications in recent years. High-impact polystyrene (HIPS) is a polymer used in 3D printing technology due to its high dimensional stability, low cost, and ease of processing. However, the ongoing development of AM creates the need to produce modern feedstock materials with better properties and functionality.

Nanocomposite Cellulose Fibres Doped with Graphene Oxide and Their Biocidal Properties.

The paper presents a method of obtaining composite cellulose fibres (CEL) doped with graphene oxide (GO) and the influence of GO nanoparticles on the structure and properties of the obtained fibres. Composite fibres (GO/CEL) were prepared using wet method from 5% CEL solutions in 1-ethyl-3-methylimidazolium acetate (EMIMAc) containing GO (0; 0.21; 0.

Parasitic zoonoses; public health and veterinary perspectives.

The importance of parasitic zoonoses continues to increase on both local and global scales as interactions between people and animals become more frequent through global travel, intensification of agriculture, habitat devastation, and changes in world trade patterns. A current and real threat is the potential for a deliberate introduction of a zoonotic disease through the prospect of bioterrorism. Parasitic zoonoses represent significant problems in public health, animal agriculture and conservation, and the meat industry.
