A transmission electron microscope was used to study the morphology of austenite and ferrite in austempered ductile iron obtained through conventional and two-step austempering process. In this investigation, two compositions of ductile iron with carbon equivalent 4.3% (alloy 1) and 3.1% (alloy 2) were selected. Both alloys were austenitized for 60...

Atom-probe tomography (APT) is a unique analysis tool that enables true three-dimensional (3-D) analyses with sub-nano scale spatial resolution. Recent implementations of the local-electrode atom-probe (LEAP) tomograph with ultraviolet laser pulsing have significantly expanded the research applications of APT. The small field-of-view of a needle-sh...

Investigations have been made to optimize various factors including pH, temperature, and substrate for enhanced polyhydroxybutyrate (PHB) production in Botryococcus braunii which serves as a pioneer for production of bioplastic (PHB). Polyhydroxybutyrate is a natural, decomposable polymers accumulated by the microorganism under different nutritiona...

Gold being the most biocompatible metal nanoparticle has become an important biosynthesized drug to be studied in recent field of bioscience. The fungus Aspergillus fischeri has been isolated from fruit crop and thus exploited for the synthesis process. Synthesized GNPs were characterized by UV–visible spectroscopy showed absorption spectra in the ...

In the last two decades, the third-dimension has become a focus of attention in electron microscopy to better understand the interactions within subcellular compartments. Initially, transmission electron tomography (TEM tomography) was introduced to image the cell volume in semi-thin sections (similar to 500 nm). With the introduction of the focuse...

The natural gabbro samples were deformed at temperature ranging from 700 to 1150 °C with strain rate steps of 1 × 10−4, 2.5 × 10−5, 6.3 × 10−6 s−1. The mechanical data show that sample experiences gradual transition from semi-brittle flow to plastic flow, corresponding to a systematically decreasing stress exponent n with the increasing temperature...

The project applied analytical facilities to characterize the composition and mechanical properties of osteoporosis in maxillary bone using an ovariectomized rat model. It was found that osteoporotic jaw bone contained different amount of trace elements in comparison with the normal bone, which plays a significant role in bone quality. The knowledg...

Despite the widespread use of silica nanoparticles (SiO2 NPs) in biological and medical fields, their adverse effects have not been clearly elucidated. In this study, spherical SiO2 NPs with a 50 nm diameter were used to study their interaction with HaCaT cells. SiO2 NPs were found to be readily internalized into HaCaT cells and localized in the cy...
