Of course, with Martin being one of just two starting rookie running backs this season, that accomplishment isn't exactly back-of-the-bubble-gum-card material.
Natural ramie fibers contain gum-like material that has to be removed before most application.
The textiles were also observed using a scanning electron microscope, and the enzyme-treated sample showed a smoother surface, suggesting that the gum-like material was mainly removed by pectate lyase PEL168P.
The fibers were also observed using an SEM, and the sample after biochemical treatment showed the smoothest surface in our experiments, suggesting that the gum-like material could be mostly removed by the combined method.
The DLF is produced from waste engine lubrication oil purified from dust, heavy carbon soot, metal particles, gum-type materials and other impurities.
Gum-like materials from natural ramie fibers are soluble at high temperature and alkaline conditions, so chemical degumming is usually performed with alkaline treatment at high temperature, which causes serious environmental pollution.
Ms. Romero also favors chewing gum, another everyday material related to rubber — and to Mexico, since chicle sap comes from a tree in the Yucatán.
ATR FTIR and Raman methods showed the characteristic bands of lithopone and lead white as a ground material, gum Tragacanth as a binder, and chrome oxide green, mars yellow, mars red as a pigment.
The other important NWFPs are bamboo and rattan and to a lesser extent tanning barks, fibres for rope-making, scented woods and barks, gums, resins, roofing materials, dyeing materials, birds nests, honey and beeswax, lac and medicinal plants.
