Electroactive biomaterials are fascinating for tissue engineering applications because of their ability to deliver electrical stimulation directly to cells, tissue, and organs. One particularly attractive conductive filler for electroactive biomaterials is silver nanoparticles (AgNPs) because of their high conductivity, antibacterial activity, and ability to promote bone healing. However, production of AgNPs involves a toxic reducing agent which would inhibit biological scaffold performance. Thi...

Abstract The primary Waste Heat Boiler (WHB) in an ammonia plant experienced cap leaking and the outer tube rupture after ten months since the last repair and replacement (total retubing). The leaking cap and the outer tube materials are low carbon steel SA-204 Gr. B and SA-209 Gr. T1a. The inappropriate vertical part of the leaked cap, which is 2.4 mm shorter than the design, might trigger turbulence flow inside the cap and lead to flow-accelerated corrosion (FAC), as suggested by the appearanc...

Zinc oxide (ZnO) has been considered as one of the potential materials in solar cell applications, owing to its relatively high conductivity, electron mobility, stability against photo-corrosion and availability at low-cost. Different structures of ZnO materials have been engineered at the nanoscale, and then applied on the conducting substrate as a photoanode. On the other hand, the ZnO nanomaterials directly grown on the substrate have been attractive due to their unique electron pathways, whi...

The ability of music has a positive impact on the balance of thinking. The purpose of this study is to determine whether the musical ability has a direct effect on the ability of abstraction of native numbers of elementary school students at a low level. This is survey research as an evaluation stage for the development of elementary thematic learning models in Kota Bengkulu, Indonesia. The research sample was 95 elementary school students in Kota Bengkulu. The instruments of this research were ...

Alzheimer is one of degenerative disease that slowly destroys memory and cognitive ability. Currently, magnetic resonance imaging (MRI) technique combined with contrast agent is widely used to detect this disease at early stage because MRI offer better safety for patient with zero long term risk. To obtain accurate result, it is favorable that contrast agent has ability to accumulate effectively in the brain tissue that has been affected by Alzheimer. One of strategy to increase their target abi...

Seven out of 12 pieces of hangers for superheater pipe were failed after one year in service. Failure analysis has been conducted to find out the root cause of failure. Hanger material is ASTM A182 Grade F22 Class 1. Fractography examinations revealed that the fracture mode is due to mechanical fatigue. Tensile test results show a tensile strength of 1015 MPa which is far beyond the minimum standard requirement of 415 MPa. The hardness of the failed hanger is between 270 to 325 HB, and un-failed...

Heterogeneous fenton catalyst is one of the promising technologies for destruction of persistent and non-biodegradable pollutant in wastewater, such as dyes from textile industries. Previously, bacterial celluloses (BCs) were used as catalyst support of fenton catalysts to improve their catalytic activity. However, reusability of fenton catalyst@bacterial celluloses were not explored yet. Herein, fenton catalyst@bacterial celluloses were prepared using sol gel method with precursor concentration...

Hydraulics tubing austenitic stainless steel 316L for offshore instrument was failed due to pitting corrosions attack. This research aims to determine the root causes of tube leakage by visual examination of new and failed tube, scanning electron microscope (SEM) examination, deposits analysis by energy dispersive spectroscope (EDS), and microstructural analysis by light microscope. The examination results show that pitting corrosions were originated from surface defects as residences for deposi...
