concentration of carrier is higher at interface than surrounding. So, the carrier diffuses.
The built-in potential by different work functions of the electrodes affects.
1. sp2-hybridization of the valence electrons of two carbon atoms lead to molecular π- and σ-bondings.
2. Electrons in π bond are less influenced by nuclear relatively.
The overlap of molecular orbitals (MO’s) in
particles of semiconductor material with the size so small that the electron energies that can exist within them are limited. These energy levels, defined by the size of quantum dots, in turn define the bandgaps. The dots can be grown to any needed size, allowing them to be tuned across a wide variety of bandgaps without changing the underlying material or construction techniques.[6] In typi
Ⅲ Flocculation
The purpose of flocculation is to uniformly mix coagulated water to produce either settleable or filterable floc and accelerate the rate of particle collisions, causing the agglomeration of electrolytically destabilized colloidal particles into settleable and filterable sizes.
Considerations of flocculation are:
1. Baffling to prevent of flow short-circuiting
2. Tapered
virus particles and virus within infected immune cells.
If infected with HIV, immune cell CD4+T-lymphocytes in our body are infected and destroyed by HIV. then immunity is decreased and results in various infectious diseases, tumors and death. This condition that begin to appear the body's immunity decreased, infectious disease and tumors is called AIDS, or Acquired Immune Deficiency Syndrome.
particles that can carry the drug molecules to the target safely.
5.2.2 Nanocarriers - Nanoparticles
Before starting with the functionalization of nanoparticles, it is important to keep in mind a range of useful properties we wish to have in any drug delivery across the BBB(Blood brain barrier). In this context, owing to their small size, customizable surface, improved solubility, targete

of the reported procedures for rod formation, seedmediated growth has been by far the most efficient and popular approach. The role played by the seed particle is also critical. Furthermore, the presence of small amounts or silver nitrate during the synthesis has a dramatic effect on the final shape and crystalline structure if the particles.

concentration, and oxygen demand are uniform throughout the tank. An advantage of the CMAS process is the dilution of shock loads that occur in the treatment of industrial wastewaters. The CMAS process is relatively simple to operate but tends to have low organic substrate concentrations(i.e., low F/M ratios)that encourage the growth of filamentous bacteria, causing sludge bulking problems.

Concentration reductions and constituent concentrations are difficult to achieve.
May not be effective for high constituent concentrations
Presence of significant heavy metal concentrations may inhibit microbial growth.
Volatile constituents tend to evaporate
