Abstract

Bone scaffolding is an alternative solution to bone therapy, which is currently being developed in tissue engineering. This effort aims to produce a bone scaffold with a shape and specification according to bone therapy's needs. 3D printing is a scaffold fabrication method with promising prospects because it can produce scaffolding with physical characteristics as needed, both pore and physical. The method used in this article is a formal review to review various national and international literature using articles from 2000 to 2020 with the keywords "scaffold," "3D-printing", "bone," and "natural sources." The results of this article present various aspects regarding the use of 3D printing for scaffolding. Some aspects that are considered are how 3D printing works, the type of material used, and the scaffold's characteristics. It aims to get a clearer picture of the use of 3D printing, both its prospects/potential, application challenges, and future developments.

Abstract

The use of solar energy to satisfy renewable energy in Indonesia has great potential. To improve the efficiency of solar collectors, some researchers proposed solar collectors that equipped by nanofluids as working fluids. CuO-based nanofluids are known as nanofluids that have excellent conductivity. The purpose of this study is to synthesise CuO nanofluids through egg white mediation methods, and it will be applied to simple distillation systems. Generally, the synthesising process is arranged based on the modification of the sol-gel method, and by the calcination, it will leave metal oxides, namely CuO-nanoparticles. The calcination temperature variation used is 150℃; 300℃; 500℃ and 700℃. According to Debye-Scherrer equations, it is known that, in optimal condition, we obtain CuO crystallite by the size is 42 nm. The use of CuO nanofluids can increase the conductivity of fluids and can increase the effectiveness of ethanol distillation by 81%.
