SYNTHESIS OF BIODIESEL: A CONTEXTUALIZED EXPERIMENT PROPOSAL FOR THE GENERAL CHEMISTRY LABORATORY. The contextualized understanding of concepts in Chemistry by students from other areas is a challenging task. In this experiment, the synthesis of biodiesel is done by base catalyzed transesterification of refined soy oil with methanol at room temperature and common glassware found in any chemistr...

Long-tem digital preservation in e-Science domains

Scientists are facing an eminent data deluge, which imposes several challenges on the way that data is managed and analyzed. Several communities like in biology, medicine, engineering or physics, manage large amounts of scientific information. It usually includes large datasets of structured data (e.g., data captured by sensors), physical or mathematical simulations, and several highly speciali...

Why STEM Not TEM?

The TEM The TEM has a similar optical configuration to an optical microscope. A flood beam of electrons illuminates a thin sample. The electron transmitted through the sample are projected onto a viewing screen or camera for observation (Figure 1). Samples must be thin (around 100 nm) and the beam energies must be high. Electrons may either pass through the sample without being scattered or may...
