Polyacrylamide Molecular Weight and Charge Effects
Polyacrylamide (20 kg ha −1) was sprayed onto the soil in liquid form. Soil material was exposed to rainfall simulation in the laboratory. Infiltration rate was used as an indicator of soil surface sealing. Polyacrylamide increased infiltration rates on all three soils relative to the control.
Soil erosion affects soil productivity and environmental quality. A laboratory research experiment under simulated heavy rainfall with tap water was conducted to investigate the effects of anionic polyacrylamide (PAM) application rates (0, 0.5, 1.0, and 2.0 g m −2) and molecular weights (12 and 18 Mg mol −1) on runoff, soil erosion, and soil nutrient loss at a slope of 5°.

Soil Sci. 91: 917-924. Soil erosion caused by increasing runoff and soil disturbances is a severe problem on steep rocky slopes. One possible soil erosion control measure is the application of polyacrylamide
Polyacrylamide (PAM) has been demonstrated to reduce erosion under many conditions, but less is known about the effects of its application method on erosion and concentrations in the runoff water.

1 Introduction. Encapsulation is the process of entrapping bioactive molecules (e.g., vitamins, minerals, antioxidants, fatty acid, lutein, and lycopene) and living cells (e.g., probiotics) within carrier materials (Nedovic, Kalusevic, Manojlovic, Levic, & Bugarski, 2011).Encapsulation is the most effective technique to protect probiotic bacteria during processing and storage (Kanmani et al

Resveratrol is a naturally occurring polyphenol that provides several health benefits including cardioprotection and cancer prevention. However, its biological activity is limited by a poor bioavailability when taken orally. The aim of this work was to evaluate the capability of casein nanoparticles as oral carriers for resveratrol.
