Agave, commonly known as “maguey” is an important part of the Mexican tradition and economy, mainly used for production alcoholic beverages, such tequila. Industrial exploitation generates by-products, including leaves, bagasse, fibers, that can be re-valorized. Agave composed cellulose, hemicellulose, lignin, fructans, pectin, well simple carbohydrates. Regarding functional properties, fructan...

this paper describes the effects of reinforcement by randomly distributed nylon fibers and addition of nanoclay on some engineering properties of a typical asphalt concrete. the properties of asphalt concrete reinforced by different percentages of 25 mm nylon fibers have been compared with those of the mixtures containing different percentages of nanoclay and those in which both the fibers and ...

the performance of asphaltic pavements during their service life is highly dependent on the mechanical properties of the asphaltic layers. therefore, in order to extend their service life, scientists and engineers are constantly trying to improve the mechanical properties of the asphaltic mixtures. one common method of improving the performance of asphaltic mixtures is using different types of ...

Halloysite nanotubes (HNTs) are proven nanocontainers and nanocarriers. Silver nitrate (Ag) zinc sulfate nanoparticles (Zn) known for their antimicrobial properties. This study incorporated Ag Zn-coated HNTs in electrospun polylactic acid (PLA) nanofiber composite. An efficient 'green' method of coating Zn on the HNT surface was used to metal coat HNTs. The resulting PLA fibers were characteriz...

Abstract The prevention of bacteria colonization by immobilizing proteins with antimicrobial activity onto cotton fabrics was investigated. Such coatings have potential applications in medical dressing materials used wound care and healing. Two lysozyme hydramacin-1 (HM-1) were surface immobilized through two linkers (3-aminopropyl) triethoxysilane (APTES) citric acid the presence water soluble...

in this research the possibility of vine pruning fibers in combination with wood fibers was studied in order to fabricate medium density fiberboard. vine pruning fibers content in three levels of 0/100, 30/70 and 60/40 (weight percent) and press time in three levels of 4, 5 and 6 minutes were as variable factors. one layer panels with a density of 0.65 g/cm3 and thickness of 15 mm were made. th...

introduction: to recognize the myelinated nerve fibers of the external and extreme capsules in human brain. materials and methods: 10 adult and normal brains (20 hemispheres) from both sexes were studied using 15 mm serial secions in all three cardinal planes after fixation and processing. these sections were stained by klüver – barrera and heidenhin – woelcke methods. results: some fibers from...

The application of fibers to reinforce cementitious materials is a well-known subject. At first, asbestos fibers are used in industrial process to produce fiber reinforced cement sheets. Thereafter, various types of synthetic fibers are produced and used as asbestos substitutes. The aim of the present work is to evaluate the effect of synthetic fibers on the flexural behavior of cementitious co...

Cellulose nanofibers (CNF) are renewable, biodegradable, and non-toxic biopolymers; however, they have not been widely adopted as an additive by the food industry. In this study, CNF functionality was improved through chemical modification. Antioxidant antimicrobial were produced esterification of with phenolic acids. esterified vanillic or cinnamic acid using two different esterifying agents: ...
