Summary of "Multifunctional diesel exhaust emission soot coated sponge for water treatment."

We demonstrated that a pollutant and waste, diesel exhaust emission soot (DEES) can be used as an absorbent to remove oil and organic pollutants from wastewater. The diesel exhaust emission soot coated sponge (DEES sponge) was prepared using the dip-coating method. Prepared DEES sponge was found hydrophobic in nature as the contact angle between water drop and its surface was recorded to be 147°. The DEES sponge showed high absorption capacity with various oils, without any surface modifications and pretreatments. Highest oil absorption capacity was found to be 39 g/g for engine oil. Excellent separation efficiency was recorded (max. 98.5% for engine oil). It shows promising recyclability having 95% efficiency even after 10 cycles. DEES sponge also demonstrated the capability to be used as an adsorbent due to its ability to absorb pollutants like methylene blue (MB), ciprofloxacin, and detergent from the water. It was able to adsorb 93% of the dye MB from its aqueous solution having concentration of 15 μM.

Sterile, gelatin-base surgical sponge applied topically as an adjunct to hemostasis when the control of bleeding by conventional procedures is ineffective to reduce capillary ooze or is impractical. (From AMA Drug Evaluations Annual, 1994, p797)

Specialized regions of the cell membrane composed of pits coated with a bristle covering made of the protein CLATHRIN. These pits are the entry route for macromolecules bound by cell surface receptors. The pits are then internalized into the cytoplasm to form the COATED VESICLES.

TRANSPORT VESICLES formed when cell-membrane coated pits (COATED PITS, CELL-MEMBRANE) invaginate and pinch off. The outer surface of these vesicles is covered with a lattice-like network of COP (coat protein complex) proteins, either COPI or COPII. COPI coated vesicles transport backwards from the cisternae of the GOLGI APPARATUS to the rough endoplasmic reticulum (ENDOPLASMIC RETICULUM, ROUGH), while COPII coated vesicles transport forward from the rough endoplasmic reticulum to the Golgi apparatus.

Vesicles formed when cell-membrane coated pits (COATED PITS, CELL-MEMBRANE) invaginate and pinch off. The outer surface of these vesicles is covered with a lattice-like network of the protein CLATHRIN. Shortly after formation, however, the clathrin coat is removed and the vesicles are referred to as ENDOSOMES.

Tablets coated with material that delays release of the medication until after they leave the stomach. (Dorland, 28th ed)
