the charge material - a molecular species that contains the desired element - is a gas at room temperature. (Liquids with an appreciable vapor pressure at or near room temperature may also be used.)
A standard gas handling system connects the external gas canister to the growth chamber.

chemical pathway revealed unexpected factors responsible for InP formation and crystallization, prompting discovery of the solution-liquid-solid (SLS) crystal-growth mechanism.4 The resulting insights enabled solution-phase synthesis of the crystalline III-V (13-15) compounds InP, InAs, and GaAs under comparably mild conditions from simpler organometallic precursors than were employed in eq 1.4 H
material or is curve . = bending strength) is lacking.
Iron frame concrete method of construction is making thereby.
Advantage of RC (Reinforced Concrete) structure is as following.
1) high economic performance
2) because resources expense is inexpensive than steel-frame structure) corrosion resistance that prevent corrosion of interior reinforcing rod because is alkalinity is security
What is Bioenergy?
Bioenergy is renewable energy made available from materials derived from biological sources. Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, wood waste, straw, manure, sugarcane, and many other byproducts from a variety of agricultural processes.
So, Why do we produce Bioenergy?
One reason governments
1] bioethanol process
① pretreatment of raw material
To increase the effectiveness of fibrin degradation, pretreatment is necessary. The purpose of pretreatment improves the efficiency of the reaction (hydrolysis) by converting cellulose and its chemical composition and physical form and especially improves the accessibility of the enzyme.
