Analysis of Phenomenon at Quantum Capacitance Limit of SNWFET using FETToy

In The proposed paper several interesting phenomenon that happens at Quantum Conductance Limit (QCL) like transconductance of One Dimensional-Silicon Nano Wire Field Effect Transistor (1D-SNWFET), mobile electron density and injection velocity is studied and simulated using Fettoy simulation tool. The selected gate material in silicon nanowire field effect transistor is SiO2 with K=3.9 and HFO2 with K=20. A coaxial SNWFET is simulated and the results illustrate the essential physics and peculiarities of 1D nanowire FETs, such as the saturation of channel conductance at full degenerate limit and the saturation of transconductance at the quantum capacitance limit and the full degenerate limit

Enzyme production from food wastes using a biorefinery concept

According to Food and Agricultural Organization (FAO), one-third of food produced globally for human consumption (nearly 1.3 billion tonnes) is lost along the food supply chain. In many countries food waste is currently landfilled or incinerated together with other combustible municipal wastes for possible recovery of energy. However, these two options are facing more and more economic and environmental stresses. Due to its organic- and nutrient-rich nature, theoretically food waste can be converted to valuable products (e.g. bio-products such as methane, hydrogen, ethanol, enzymes, organic acids, chemicals and fuels) through various fermentation processes. Such conversion of food waste is potentially more profitable than its conversion to animal feed or transportation fuel. Food waste valorisation has therefore gained interest, with value added bio-products such as methane, hydrogen, ethanol, enzymes, organic acids, chemicals, and fuels. Therefore, the aim of this review is to provide information on the food waste situation with emphasis on Asia–Pacific countries and the state of the art food waste processing technologies to produce enzymes
