Zirconia nanoparticles were prepared by the precipitation and ageing methods. The precipitation method was performed by adding ammonium solution to the aqueous solution of zirconium chloride at room temperature. The ageing method was performed by leaving ... see more

Zirconia (ZrO2), an inorganic material, is a very fascinating material due to its high mechanical strength and fracture toughness. The synthesis is carried out by using the co-precipitation method using optimum content of zirconium oxychloride octahydrate... see more

A low-temperature hydrothermal synthesis technique was employed as a medium to produce ceria-zirconia mixed oxides particles at temperatures of 200–300 °C and pressure of 10 MPa in a batch process. At these conditions, the average crystallite sizes of cer... see more

A study was carried out to compare the ballistic performance of high purity alumina and zirconia-toughened alumina (ZTA) using depth of penetration (DoP) test configuration against 7.62 mm armour piercing (AP) ammunition. The effect of tile thickness on t... see more

Sol-gel method has been used to coat multiwalled carbon nanotubes (MWCNTs) with zirconia at room temperature and the coated tubes were sintered at high temperature. The samples were characterised by Raman spectroscopy, x-ray diffraction, environmental sca... see more

Doping of lithium (Li+) cations results in stabilised zirconia, especially in tetragonal (t)crystal structure, i.e., Li+: t-ZrO2. It is useful to vary oxygen vacancies in Li+: ZrO2 powders. TheLi+: t-ZrO2 powder having 1-5 mol per cent Li+, are obtained b... see more

The suspension of hydrous colloidal zirconia particles (CZPs) was prepared from zirconium oxychloride solutions via thermal hydrolysis at acidic condition and at boiling point of 110 ºC for 72 h. Characterization of the obtained suspension and dried solid... see more

Technetium-99m (99mTc) plays a major role in diagnostic nuclear medicine and has not yet been replaced with any other radionuclides. It is available through the 99Mo/99mTc generator. The use of low-specific-activity 99Mo for 99Mo/99mTc generator applicati... see more

Biomassa adalah bahan organik yang dihasilkan melalui proses fotosintetik. Keberadaan lignin pada dinding sel akan menghambat selulosa untuk dikonversikan menjadi produk. Delignifikasi akan membuka struktur lignoselulosa agar selulosa menjadi lebih mudah ... see more
