Abstract Background Ecological protection of slope surfaces by vegetation is one the effective methods to reduce soil erosion. However, surface often has problems poor structure and low water use efficiency, which not conducive plant growth. Super absorbent resin (SAR) as a new type retention agent can effectively improve slopes. The study was designed evaluate effect mechanism SAR on aggregate...

Introduction Many analysts 1,2,3 identify carbon dioxide (CO 2) capture and separation as a major roadblock in efforts to cost effectively mitigate greenhouse gas emissions via sequestration. An assessment 4 conducted by the International Energy Agency (IEA) Greenhouse Gas Research and Development Programme cited separation costs from $35 to $264 per tonne of CO 2 avoided for a conventional coa...

Over the past 50 years, absorbent hygiene products such as baby diapers and incontinence products have become essential features of modern day life. Through innovation and enhanced technology, their design, composition and performance have been dramatically upgraded from their early forms, and they have transformed the lives of millions of people, improving their quality of life. Skin health re...

BACKGROUND: Nutrient management plays an important role for obtaining satisfactory yields and to increase crop productivity. Also keep soil moisture under drought stress is an important factor to produce economical production, so super absorbent polymer has great role to achieve mentioned goal. OBJECTIVES: Present study was conducted to evaluate the effect of ...

decreasing water loss and increasing the irrigation times are basic methods to develop agriculture, success in natural recourse projects, minimize the stress to planted bushes in natural fields and increase the productivity of soil and water sources. the use of super absorbent is one of these strategies to achieve these goals. the main purpose of this research was to study the effect of super a...

conserving water resources and protecting them from pollution are of high account in the natural cycle of our life. this study has tried to determine the refining potential and capacity of water hyacinth (eichhornia crassipes) in order to remove the cadmium from water, studying the influence of factors such as initial concentration of cadmium, contact time, absorbent mass, and ph. results have ...

This study reports a preparation method of a new moisture swing sorbent for CO2 capture from air. The new sorbent components include ion exchange resin (IER) and polyvinyl chloride (PVC) as a binder. The IER can absorb CO2 when surrounding is dry and release CO2 when surrounding is wet. The manuscript presents the studies of membrane structure, kinetic model of absorption process, performance o...
