At DOE sites, significant amounts of Job Control Waste (JCW) need to be disposed. This JCW is generated and contaminated with polychlorinated biphenyls (PCBs) during clean-up operations. A commercial, plant-based absorbent material, “Toxi-dry”, is used extensively for decontamination and decommissioning of DOE waste sites and is classified a hazardous JCW after use. In this investigation, 1,2,4...

Chitin-silica represents a potentially useful superdisintegrant in many pharmaceutical applications. The "intimate" association between chitin and silica, without evidence of chemical reaction, creates an insoluble, hydrophilic, highly absorbent inert material. The new superdisintegrant is characterized by superiority in water uptake and water penetration, with no gelling hindrance effects, as ...

Magnetic porous microspheres are widely used in modern wastewater treatment technology due to their simple and quick dye adsorption and separation functions. In this article, we prepared porous polymethylmethacrylate (PMMA) microspheres by the seed-swelling method, followed by in situ formation of iron oxide (Fe₃O₄) nanoparticles within the pore. Then, we used diazo-resin (DR) to encapsulate th...

Abstract Super absorbent polymer is a new type of functional material that has been researched in recent decades. Due to its special structure and water-absorbing water-retaining properties, it broad field drought resistance, soil improvement crop protection. It conditioner agricultural drought-resistant water-saving materials. Combining with fertilizers prepare forestry slow-release functions,...

in order to investigate the effects of super absorbent polymer application on reduction of drought stress to corn, a split plot arrangement based on randomized complete block design with three replications was conducted at research field of agriculture faculty of ferdowsi university of mashhad during growing season of 2010-11. the main plot treatments were 1) application of 40 kg.ha-1 super abs...

Electrospun polystyrene materials have been employed as oil absorbents, but they have visible drawbacks such as poor strength at low temperature and unreliable integrity because of brittleness and insufficient cohesive force among fibers. Butyl acrylate can polymerize into flexible chains, and its polymer can be used as elastomer and adhesive material. Thereby it is possible to obtain the mater...

BACKGROUND: Drought stress and climate changes cause damage led to reduction in agricultural production. OBJECTIVES: Evaluation the impact of different levels of super absorbent polymer (SAP) on reducing the effects of drought stress on some physiological traits and activity of some antioxidant enzymes in wheat crop. METHODS: Current research...

Abstract Absorbent packaging is a form of food designed to absorb excess liquid and moisture that may be present in products. This article provides bibliometric analysis the literature on food-absorbent packaging. The was conducted using Scopus database, 121 documents were selected for study. According study’s findings, number publications absorbent has grown over time. As productive countries,...

Application strategies for avian repellents are needed to maintain efficacious repellent concentrations throughout the period of needed crop protection. We investigated the repellency of an ultraviolet (UV) feeding cue in the absence of postingestive consequences, the combination of the UV feeding cue and an UV-absorbent, postingestive repellent (i.e., a repellent that causes negative postinges...
