Herein, the dual role of trichloroethylene (TCE) in liquid-phase hydrodechlorination with Pd catalysts supported on swellable organically modified silica (SOMS), is investigated. Batch experiments TCE-soaked Pd/SOMS showed 45% higher conversion after 4 h than dry Pd/SOMS, suggesting that TCE acts as a reactant and swelling-agent. Flow performed without ethanol (external swelling-agent) exhibite...

This study examined possible feasibility of canola (Brassica napus) straws in the production of particleboard. Three-layer experimental particleboards with density 0,7 g/cm3 were manufactured using different canola straws particle ratios (0%, 25%, 50%, 75% and 100%) and urea formaldehyde (UF) adhesive. Modulus of elasticity (MOE), modulus of rupture (MOR), internal bond strength (IB), water abs...

Central composite rotatable of response surface methodology experimental design was used to determine effect of mash quantity and roasting duration on physical, pasting and sensory properties of gari. Five levels of quantity (317, 400, 600, 800 and 882.2 g) and roasting time (37.1, 35, 40, 45 and 47.1 min) were used at a fixed roasting temperature (95oC). The responses were moisture, pH, bulk d...

In this study, 4-mm-thick medium-density fiberboard (MDF) panels were heat-treated at 140 °C for 30 or 60 min and at 180 °C for 30 or 60 min. Then, 10-mm-thick lightweight honeycomb paperboards made from kraft paper (130 g/m, cell diameter of honeycomb, 14 mm; compression strength, 0.21 N/mm) were faced with the untreated and heat-treated MDF panels (thickness: 4 mm) using a two-component polyu...

Abstract The wood-water interactions of modified beech wood ( Fagus sylvatica L.) were studied. Specimens thermally at 180 (TM 1 ), 200 2 ) and 220 °C 3 acetylated (Acet), melamine formaldehyde (MF) resin (Mel) modified. Afterwards, the water vapour characteristics, i.e. sorption isotherms, equilibrium moisture content (EMC), dimensional stability specimens conditioned 30, 65 90% RH liquid abso...

The nutrient composition and flour functionality of horse gram seeds were evaluated of their flour characteristics. The objective of the present study was to evaluate horse gram seed with the aim of quantifying physiochemical and functional properties information that might serve as a guide to exploit its potential and benefits for human and animal nutrition. The proximate compositions (%) were...

Due to the fact that many application processes take place at different temperature, better examining and understanding of swelling properties as a function of temperature is essential for such application. The temperature effect on the swelling properties of commercial polyacrylic acid (PAA) hydrogel beads was investigated as a function of time and temperature. Gel bead size, swelling equilibr...

Abstract The study of repairing materials is paramount importance, considering that damage during usage can significantly impact performance and bring inconvenience maintenance work. One highly sought-after material water-swellable elastomers, known for their effect in sealing damaged materials. In this study, agar/polyurethane dual-network hydrogel elastomers were prepared, which further modif...

wood is a naturally renewable material with both continuous and isolated pore systems. wood-composite panels have the privilege of offering a homogeneous structure to be used as constructional and structural materials. however, its nature makes it susceptible to biological wood-deteriorating agents, water absorption and thickness swelling, fire, etc. using nano-materials are very easy in the wo...
