Organometallic Polymers and Materials , Vol.28 (2). Metallo-terpyridine compounds and polymers exhibit unique optical, electrical, magnetic and antimicrobial properties. Recently, metallo-terpyridine-modified cellulosic films with interesting porous structure, that exhibit these properties, have been prepared. Herein we report the use of Cu-terpyridine-modified oxidized cellulose nanofibers (OXCNF-Cu-Tpy) as membranes for treatment of effluents of paper mills to produce re-usable water. Photoactive polymeric and hybrid systems for photocatalytic degradation of water pollutants , Maria Nowakowska & Krzysztof Szczubiałka, Polymer Degradation and Stability , Vol.145. The review presents recent developments in the synthesis of polymeric photosensitizers and hybrid photocatalysts of various physicochemical and photochemical properties and their possible application for the degradation of water pollutants. The mechanisms of their action are also presented. Dissolved oxygen control strategies for the industrial sequencing batch reactor of the wastewater treatment process in the papermaking industry, Yi Man et al , Environmental Science: Water Research & Technology , online. This paper proposes two strategies for controlling the dissolved oxygen concentration in the sequential batch reactor of the wastewater treatment process in the papermaking industry. Based on a previously developed sequential batch reactor simulation model, a fuzzy logic system and a neural network are integrated with a PID controller separately. Simulation results reveal the superiority of the developed fuzzy-PID control strategy in the dissolved oxygen control of the sequential batch reactor of the wastewater treatment process in the papermaking industry. WOOD PANEL Cellulose nanofiber board, Hossein Yousefi et al , Carbohydrate Polymers , Vol.187. A cellulose nanofibre board (CNF- board) with a nominal thickness of 3 mm was fabricated without adhesive or additive. To provide comparison, a cellulose fibre board (CF-board) was also fabricated. A novel cold pre-press apparatus was made to dewater highly absorbent CNF gel prior to drying. The specific flexural and tensile strengths of CNF-board obtained were higher than those of CF-board as well as some other traditional wood- based composites, polymers and structural ASTM A36 steel. Hydrothermal treatment of strand particles of pine for the improvement of OSB panels, Amélia Guimarães Carvalho et al , European Journal of Wood and Wood Product s, Vol.76 (1). The aim of this study was to evaluate the effect of hydrothermal treatment in strand particles of pine used for oriented strand boards (OSB) production. Strand particles of pine were hydrothermally treated at 130, 150 and 170 °C for 7 and 21 min, for the determination of chemical composition, pH, equilibrium moisture content, particles mass loss, and contact angle of these particles with phenol – formaldehyde resin. Stiffness modelling of particles in the core layer for the manufacturing of wood- reduced particleboard, Matthias Schneider et al , European Journal of Wood and Wood Products , Vol.76 (3). A great demand for wood material has led to an increase in the price of industrial wood in the past and will raise it even further in future. Industry and research have reacted to this increasing price of wood, for example, by developing weight- reduced particleboard. One approach to achieve this reduction in weight is to use suitable chip geometries in the core layer instead of lightweight, resource-saving filling materials. For this purpose, particle geometries were analysed with regard to this property within a project for the development of weight-reduced particleboards.
