This paper presents results from a study of fibres extracted from Zostera marina eel-grass collected from the Baltic coast. This species of sea-grass is shown to contain small diameter (around 5 μm) fibres composed of ∼57% cellulose, ∼38% of non-cellulosic polysaccharides (mainly xylan) and ∼5% of residual matter so-called Klason lignin. This composition is quite different to that of commonly u...

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...

Bio-reduction of composite materials is the modern approach to facilitate researchers avoid toxic chemical exposure during reduction process. In this study, green graphene oxide using Abutilon indicum (Tamil name: Thuthi) plant leaves extracted from various solvents were used as filler material (0.3, 0.6 and 1 wt.%) in glass fibre epoxy composite. Compression moulding process was adopted fabric...

plastics are well-established for convenient and safe packaging and distribution of food and feed goods. at present, this special sector of the plastic market displays remarkably increasing quantities of its annual production. caused by the ongoing limitation and strongly fluctuating prices of fossil feedstocks, classically used for plastic production, there is an evident trend to switch toward...

the aim of the present study was to assess the bio-trickling filter startup for the treatment ofwastewater produced by pegah dairy company at psychrophilic condition. the startup time of a bio-tricklingfilter is directly proportional to the concentration of microbial population. abio-trickling column with a height of150 cm was packed with lava rocks with the liquid recirculated through the pack...

many materials have been introduced for apexification each having their own advantages and disadvantages. this case report aims to present a new method of apexification using a combination of deproteinized bovine bone mineral (dbbm) and enamel matrix derivative (emd). after irrigating the canal of the maxillary right canine with 2.5 % sodium hypochlorite, a mixture of bio-oss and emd was packed...

Bio-based products are paving a promising path towards greener future and helping win the fight against climate change global warming mainly caused by fossil fuel consumption. This paper aims at highlighting acoustic, thermal, mechanical properties of hemp-based biocomposite materials. Change in sound absorption as result hemp fibers particle reinforcement discussed this paper. The thermal char...

The clay–microbial consortium is ubiquitous in the soil near mining area and plays an important role transport of heavy metals. In this study, Chlorella sorokiniana FK was separated from lead–zinc mine tailings. montmorillonite– system as a typical case applied to study Pb(II) biomineralization presence usually co-existent Ca(II) further reduce migration transformation environment. showed good ...

This study proposed the use of polyaniline–alkaline copper carbonate composites as anti-corrosion and anti-biofouling concrete additives established a set high-dispersion preparation methods for this composite additive. The effects in were investigated marine environments via specimens, actual sea suspension experiments, mechanical property tests, biological attachment avoidance tests. experime...
