Statistical analysis of sustainable production of algal biomass from wastewater treatment process, Indu Ambat et al, Biomass and Bioenergy , Vol.120. Algal biodiesel is one of the most promising renewable and eco-friendly source of energy for transportation, when algae is produced from wastewater. During the process, both goals of biodiesel production and wastewater treatment could be achieved simultaneously. However, the optimal condition for algae production remained unanswered. Algal biodiesel could be produced from various wastewater treatments. In this study the relationship between biomass production versus lipid productivity in various wastewater sources is statistically analysed. A green composite hydrogel based on cellulose and clay as efficient absorbent of colored organic effluent, Qiyang Wang et al, Carbohydrate Polymers , Vol.210. This work has developed a convenient way of constructing wood cellulose and clay green composite hydrogel as efficient adsorbent of coloured organic effluent. The simple procedure and cost effective wood cellulose as raw material for the composite absorbent construction presented in this research are favourable for industrial applications. Phosphonium-Enhanced Chitosan for Cr(VI) Adsorption in Wastewater Treatment, Sebastian Sessarego et al, Carbohydrate Polymers , Vol.211. Adsorption is a commonly used method for industrial wastewater treatment because of its low-cost, easy operation and high efficiency. In this work, chitosan was crosslinked and functionalised with a low-cost phosphonium salt, tetrakis(hydroxymethyl)phosphonium sulfate (THPS), to enhance its adsorption capacity for Cr(VI). WOOD PANEL Application of surface chemical functionalized cellulose nanocrystals to improve the performance of UF adhesives used in wood based composites - MDF type, Hossein Khanjanzadeh et al, Carbohydrate Polymers , Vol.206. The aim of this research was to investigate the effect of functionalised cellulose nanocrystals (CNC) on the performance of urea-formaldehyde (UF) adhesive for the production of medium density fiberboard (MDF). Surface modification of CNC was performed using 3- Aminopropyltriethoxysilane (APTES). Some physical and thermal properties of reinforced and neat UF as well as formaldehyde emission and some mechanical (modulus of rupture (MOR), modulus of elasticity (MOE) and internal bond strength (IB)) and physical properties (thickness swelling (TS) and water absorption (WA)) of the resulting MDF panels were determined. Quasi-static and dynamic response of oriented strand boards based on balsa wood waste, G.Barbirato et al, Composite Structures , Vol.219. This work presents an evaluation of the performance of Oriented Strand Boards (OSB) panels based on balsa wood (Ochroma Pyramidale) waste agglomerated with castor oil polyurethane resin. In this study, were evaluated OSB panels with different densities (300 kg/m 3 , 400 kg/m 3 and 650 kg/m 3 ), with 10 mm thickness and castor oil polyurethane resin in different contents (11% and 15%). The OSB panels were preliminary characterised by physical and quasi- static mechanical tests to identify the class of application of this material according to the recommendations of standard EN 300: 2002. Subsequently, the OSB panels were characterised by low velocity impact tests.
