thermaland electrical properties for three typical thermoelectric materials, Bi2Te3, SiGe, and single-crystal silicon, at room temperature
The only different between passive and active solid-state cooling is the utilization of a thermoelectric module (TEM) sandwiched between the processor and the passive or active heat sink.

The Barrett-Joyner-Halenda (BJH) method for calculating pore size distributions is based on a model of the adsorbent as a collection of cylindrical pores. The theory accounts for capillary condensation in the pores using the classical Kelvin equation, which in turn assumes a hemispherical liquid-vapor meniscus and a well-defined surface tension.
1. Introduction
1) Definition of preservation and food-spoilage micro-organisms
Food preservation is the process of treating and handling food to stop or greatly slow down spoilage (loss of quality, edibility or nutritive value) caused or accelerated by micro-organisms. Some methods, however, use benign bacteria, yeasts or fungi to add specific qualities and to preserve food (e.g., cheese, wine
(1) Project Objective
To develop a new commercial product that is valuable, feasible, and practical in the real market.
(2) Deciding The Market for The New Product
In this world, there are myriad markets, consumers, products. However, considering our company's technologies(internal factor) and marketability(external factor), we chose the market of kitchen utensils for our new product.
