Abstract
Lignocellulosic ethanol production process, pretreatment, saccharification, fermentation, purification is divided into four steps.
The goal of the preprocessing step, after separating from the other ingredients, such as lignin and cellulose, which have the characteristics of hard and complex structures belonging to the upstream process, the microorganisms in the process of sacc
organic light emitting diode(OLED)
LED's emissive electroluminescent layer is composed of a film of organic compounds.
This layer of organic semi-conductor material is formed between two electrodes, where at least one of the electrodes is transparent.
OLED can be used in many display devices.
Active matrix OLED has an integrated electronic backplane made from thin film transistor
2000 B.C - The first recorded (The Susruta Samhita, Sanskrit writing) water purification began with the Egyptians. It is said that impure water should be boiled over a fire, heated in the sun, have a hot iron dipped into it or purified by filtration through sand and course gravel.
A major step in the development of desalination technologies came in the 1940s during World War II when various m

Digestion tank production gas is a biogas produced by artificial anaerobic digestion of organic wastes with bacteria in the digestion tank. This can be divided into mergence gas which produce bio-gas by putting more than two of them together, among the organic waste gas, waste water gas, livestock· sewage gas, sewage sludge gas, depending on the type of organic waste. Because they are artificial
