Bioethanol, which is produced from renewable raw materials, has lower emissions than fossil fuels [4].
A simple distillation device is made by assembling some used materials and electronic components to produce coconut liquid bioethanol.
In addition, the cost of producing bioethanol from coconut is also relatively lower than other raw materials such as corn or sugarcane, making it more economical to be widely applied [6].

Introduction Turning has been used for centuries mainly for cutting various types of metallic materials.
A growing demand for machining these intractable materials requires new advanced turning technologies [1].
Active materials, in particular piezoelectric or magnetostrictive materials, are used widely to make actuators because they can easily convert high-frequency electrical energy into mechanical vibration [4].

This paper presents a numerical strategy to model nonlinear damage behavior of RC members based on level of material.
For steel material in RC members, we adopt bilinear kinematic hardening model.

Electrode material as an important part of supercapacitors has also drawn considerrable attention, many researches have been foused on electrode material.
Among polymers, polyaniline has emerged as the one of the most promising class of active materials for electrochemical capacitor, due to its high capacitive characteristics, low cost, easy processing and environmental friendliness.
