Silver nanoparticles can be coated on common polyurethane (PU) foams by overnight exposure of the foams to nanoparticle solutions. Repeated washing and air-drying yields uniformly coated PU foam, which can be used as a drinking water filter where bacterial contamination of the surface water is a health risk. Nanoparticles are stable on the foam and are not washed away by water. Morphology of th...

In this paper, the results of an experimental study on textile thermal drying after wet processing pretreatments are presented. The mass variation of the studied samples as a function of drying time was determined using the gravimetric method at three different temperatures: 100°C, 110°C and 120°C. A polynomial model was found and established to follow the drying phenomenon of wet textile fabri...

BACKGROUND The objective was to investigate the effect of placing mats on concrete slatted floors on performance, behaviour, hoof condition, dirt scores, physiological and immunological variables of beef steers, and to compare responses with animals on out-wintering pads. Continental crossbred beef steers [n = 360; mean (±SD) initial live weight 539 kg (42.2)] were blocked by breed and live wei...

Abstract Porous cellulose nanofibril (CNF) foam was prepared by stabilizing bubbles with CNF and a surfactant then drying the stabilized wet in convection oven. The consistency of carboxymethylated (CMCNF) addition amount were controlled effects these factors on dry properties investigated. An adequate (0.02–0.04 wt%) CMCNF higher than 0.5 wt% yielded foams excellent stability. When dried at 60...

The modified aloe polysaccharide (MAP) juice developed under optimized condition was investigated to assess the effect of foaming process parameters and its optimization followed by evaluating best drying conditions for developing MAP powder from foamed non-foamed juice. selected optimizing were soy protein isolate (SPI%), carboxymethyl cellulose (CMC%), whipping time (WT) with variation in exp...

Nanofibrillated cellulose (NFC) from wood is an interesting material constituent of high strength and high aspect ratio, which easily forms networks through interfibril secondary bonding including hydrogen bonds. This has been exploited in preparation of new materials, which extend the range of properties for existing cellulosic materials. The objective is to explore processing-structure and st...
