Studi tentang smart materials cukup menyita perhatian dalam beberapa tahun terakhir, salah satunya yaitu tentang Shape Memory Alloys (SMA). Banyak penelitian yang telah dilakukan untuk mengembangkan SMA menggunakan paduan Ni-Ti, namun karena paduan terseb... see more

Cu2+ doped ZnO by green synthesis was successfully prepared by using a combination of the Sol-Gel-Sonochemical method. Duck egg albumen was used as an additive, a substitute for chemical additives, such as monoethanolamine (MEA) and diethanolamine (DEA). ... see more

Shape memory alloys (SMAs) are metal alloys with a reversible ability to recover their shape at a certain temperature after being deformed. This ability referred to as Shape Memory Effect (SME). The application of SMAs such as Ni-Ti and Cu-Zn-Al alloys us... see more

Cet article présente une étude sur la détermination du coefficient linéaire de dilatation thermique et de la capacité calorifique, dans l’intervalle de température [25-400°C] de deux alliages d’aluminium, Al-Zn-Mg et Al-Zn-Mg-Cu dans trois différents état... see more

Tetrahydropyran (THP) represents an O-containing hetero-cyclic compound that can be used as a promising solvent or monomer for polymer synthesis. In this work, Cu–ZnO/Al2O3 catalysts have been prepared by a facile precipitation–extrusion method and used f... see more

Wastewater containing heavy metals can potentially harm the human and living organisms and also damage the environment and ecosystem. Wastewater containing total copper (Cu) and zinc (Zn) over the normal threshold will result in Wilson's disease and diges... see more

Electric Arc Furnace (EAF) slag containing larnite, gehlenite, wuestite, montcellite and calcite as the main crystal phases was alkali activated using the alkali activator prepared by the mixing of two solutions, sodium silicate and NaOH. Alkali Activated... see more

Os metais pesados são importantes poluentes ambientais e a sua toxicidade é um problema de importância crescente, geralmente, em solos localizados próximos a complexos industriais, perímetros urbanos e em áreas rurais de intensa tecnologia, sendo que, as ... see more
