Cassava bagasse, a high-fiber coproduct of cassava starch processing, was used to produce lignocellulose nanofibers (LCNF) apply as reinforcement in films. LCNF-reinforced cast films were evaluated for changes structural, thermal and mechanical properties compared with control reinforced commercial grade nanoclay (Nclay). Five different types cast-films produced: no-reinforcement control, two LCNF-reinforced, Nclay-reinforced, each at 0.65 1.3% w w-1. The LCNF morphology showed the...
Abstract Mahogany is one of the most valuable woods and was widely used until it included in Appendix II Convention on International Trade Endangered Species as endangered species. wood sometimes traded under different names. Also, some similar belonging to Meliaceae family are “mahogany” or being a “mahogany pattern”. To investigate feasibility use near infrared spectroscopy for discrimination, mahogany ( Swietenia macrophylla King.), andiroba crabwood Carapa guianensis Aubl.), cedar...
Microfibrillated cellulose as a reinforcement agent has been investigated extensively due to their unique characteristics, which can reorder the structure of polymers and hydrogels leading improved mechanical properties with minimal disadvantages in terms targeted original applications. However, effect using macro- micro-fibrillated onto polyvinyl alcohol is still unknown, because ability for both be produced from freeze-thawing mechanisms – hydrogen bonding - there potential synergism....
Topological variety of robust networks from nanofibrils enables the formation strong and tough particle constructs ubiquitously.
ABSTRACT Six fillers from forestry wastes (wood, bark, cones and needles young pine trees, kraft lignin, recycled paper sludge industry wastes) were incorporated into polyurethane (PU)‐based foams prepared via free‐rise pouring method. Variable filler contents (1, 5, 10 wt %) NCO/OH ratios (0.6, 0.9, 1.2) investigated. A simple mixture (1:3) of castor oil crude glycerin (byproduct biodiesel production) was used as biobased polyol. The foam composites investigated through spectroscopy,...
We report herein for the first time how a co-electrospinning technique can be used to overcome issue of orienting cellulose nanocrystals within neat matrix. A home-built apparatus was fabricated that comprised high-voltage power supply, two concentric capillary needles, and one screw-type pump syringe. Eucalyptus-derived dissolved in N-methylmorpholine oxide (NMMO) at 120 °C diluted with dimethyl sulfoxide (DMSO) which external needle as shell solution. nanocrystal suspension obtained by...
Abstract By seeding fungus on top of industry residues, a mycelium can grow and form compact network structure; however, it may not develop due to lack optimal nutrients from the substrate. Consequently, peach-palm residues be potential alternative; so, test this hypothesis, work evaluates effect as substrate for growth based Lentinula edodes . They were also supplemented with cassava bran various sources nitrogen-ammonium sulphate, potassium nitrate, soy flour—to analyse its effects...
The effectiveness of tannic acid as antimicrobial and wound healing for burns have been shown a century; however, uncontrolled target dosage may result in undesirable side-effects. Remarkably, polyphenols compounds crosslinked with polymeric materials produce strong composite containing the beneficial properties this tannin. However, investigation crosslink structure its antibacterial regenerative are still unknown when using nanocellulose by mechanical defibrillation; additionally, due to...
