Especially, active metals require the modification maximum to escape the natural corrosion or passivation. The retention of sound performance of the metals as well as extension of their lifetime can be achieved by surface modification of coating formation. Chemical coating is one of the simple and low-cost methods of coating with great versatility including pre-treatment and post-treatment. This paper includes the most widely used inorganic and organic chemical coating methods and their fewer details and their future outlooks.

The Cuu Long delta is affected strongly by mass water from rivers of the MeKong river system such as Tieu, Dai, Ham Luong, Co Chien, Cung Hau, Dinh An and Tranh De (Hau river). The estuaries of Cuu Long delta are large with a huge amount of sediment (about 100 million tons per year) and high tide (about 4.2m) made the large tidal flats with high level of biodiversity, which is an important resource for aquaculture.

Ebook "Herrera’s ‘Plasmogenia’ and other collected works: Early writings on the experimental study of the origin of life" collects three outstanding examples of the work of Mexican biologist Alfonso Luis Herrera (1868-1943), a pioneer in experimental origins of life research. Two of the collected works appear here in English for the first time. Herrera's works represent the attempt to deal experimentally with the issue of an autotrophic origin of life, a possibility that was widely accepted prior to Alexander I.
