In 2007, research was carried out to determine the type and amount of asbestos fibers in a Croatian factory with a long history of making asbestos-containing products.Since the 1970s, asbestos fibres have been considered carcinogenic in humans i.e as a known cancer-causing agent. In the environment, asbestos fibres are inactive and naturally resist biodegradation. In time, fibres can only be gr...

Plant metabolic engineering has recently enabled the synthesis of a range of polyhydroxyalkanoates as well as a protein-based polymer. These novel compounds can be harvested from plants as a renewable source of environmentally friendly polymers or can be used to change the physical properties of plant products, such as fibres.

The ability to accurately identify fibres is of importance to conservators, allowing the most appropriate methods of treatment to be employed. Our research has concentrated on the development of an ATR FT-IR spectroscopic technique for the characterisation of cellulosic (plant) fibres. Six species of fibre were examined, taken largely from the bast group (flax, hemp, jute and ramie), along with...

In this work, the mechanical characteristics of unidirectional bio-composite materials reinforced by two types natural fibres (sisal andjuncus) were studied in order to develop new materials. The effect fibres’ extraction methods and their assembly techniques on properties elaborated composites was investigated. This is based three extracting fibres: first uses water treatment alone over a long...

The physicochemical properties of plant fibres are determined by the fibre morphology and structural features of the cell wall, which is composed of three main layers that differ in chemical composition and architecture. This composition and hierarchical structure are responsible for many of the mechanical properties that are desirable for industrial applications. As interactions between the li...

The aim of the study was an evaluation of the influence of chicken feed supplementation with plant oils contain high amount of polyunsaturated fatty acids on histochemical characteristics of meat. Chickens Vedetta were divided into three experimental groups and they were fed with feed DKA-SFA; control group and with the addition of rapeseed oil of 2.75% and vitamin E 0.015%, as well as of 8.25%...

INTRODUCTION Esca disease has become a major threat for viticulture. Phaeoacremonium aleophilum is considered a pioneer of the esca complex pathosystem, but its colonisation behaviour inside plants remains poorly investigated. MATERIAL AND METHODS In this study, P. aleophilum::gfp7 colonisation was assessed six and twelve weeks post-inoculation in two different types of tissues: in the node a...

Plant cell walls form an organic complex composite material that fulfils various functions. The hierarchical structure of this material is generated from the integration of its elementary components. This review provides an overview of wood as a composite material followed by its deconstruction into fibres that can then be incorporated into biobased composites. Firstly, the fibres are defined, ...

Cellulose hydrogels are extensively applied in many biotechnological fields and are also used as models for plant cell walls. We synthesised model cellulosic hydrogels containing hemicelluloses, as a biomimetic of plant cell walls, in order to study the role of hemicelluloses on their mass transport properties. Microbial cellulose is able to self-assemble into composites when hemicelluloses, su...
