Preparation and Characterization of Hydroxyapatite/Zinc Composites with Alginate for Bone Scaffold Application

Autor: Jane Ramadhani, Gusti Umindya Nur Tajalla, Ade Wahyu Y.P. Parmita, Riska Rachmantyo, Arie Wibowo

Publikováno v: Advances in Science and Technology.

Studies on hydroxyapatite are plentiful since the compounds are alike to the bone and sometimes combined with Zn to fabricate a longstanding structure and improve cell regeneration. However, construct a 3D model of HAp-Zn through sintering required h

Optimization of calcination temperature of lithium aluminium titanate phosphate for solid electrolytes of lithium-ion battery application

Autor: Arie Wibowo, Riska Rachmantyo, Radian Febi Indrawan, Bambang Sunendar Purwasasmita

Publikováno v: 3RD INTERNATIONAL CONFERENCE ON CHEMISTRY, CHEMICAL PROCESS AND ENGINEERING (IC3PE).

Solid electrolytes such as lithium aluminium titanate phosphate (LATP) are attractive for production of safer Lithium-Ion Battery (LIB). Unfortunately, exploitation of LATP as solid electrolytes in LIB is hindered by their low conductivity. Previousl

Effect of PEG addition and temperature on hard chromium coating using eco-friendly trivalent chromium

Autor: Ahmad Zein Eko, Aditianto Ramelan, Riska Rachmantyo, Lidya, Firmansyah Sasmita, Akmal Fauzi, Adhi Setyo Nugroho

Publikováno v: 1ST INTERNATIONAL SEMINAR ON ADVANCES IN METALLURGY AND MATERIALS (i-SENAMM 2019).

Commonly, electro deposition of chromium is carried out by using Chromium trioxide (CrO3) solution. CrO3 contains hexavalent chromium or Cr(VI) ions which is toxic and carcinogenic. Some countries such as Japan, America and the European Union includi
