Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , Safety of 1,10-Decanediol, 112-47-0, Name is 1,10-Decanediol, molecular formula is C10H22O2, belongs to alcohols-buliding-blocks compound.

Nanoindentation determination for mechanical properties of submillimeter boron carbide particles simulating fuel debris fragments
It is essential to characterize fuel debris fragments that are to be retrieved from reactors at the Fukushima Daiichi power station prior to their large-scale retrieval. Using nanoindentation (NI) test, we have determined the mechanical properties of boron carbide (B4C) particles currently used to simulate hard covalent materials as included in the debris. We also examined the measurable minimum size among the particles sized to three types and found suitable sample preparation methods. While the minimum size was limited to 1000 m among the particles fixed with grease in molding process, it was brought down to 500 m by alternative polyvinyl alcohol (PVA) films. Indentation moduli of these successfully measured B4C particles are consistent with a referential value of 431 GPa with a difference of 3.5%. Furthermore, the hardness values of the particles are slightly lower than a referential value of 21.8 GPa within uncertainty of 9%. The particle surfaces were polished enough with only the roughest #240 abrasive papers, and surface flatness was a key issue for the successful indentation but not surface roughness. As a result of the detachment caused during polishing, both 500 m particles and 100 m particles fixed with the grease were insufficiently flattened, and then the indenter was slipped on the inclined surfaces during the NI tests. The values of modulus and hardness are at the minimum for the 100 m particles at decreasing rates of 46% and 42% to the referential values. The thin uniform PVA films reduced the projection amount of the 500 m particles from the surrounding resin and prevented the particle detachment during polishing. Residual resin was distinguished from an underlaying B4C particle using the NI tests. (C) 2021 Elsevier B.V. All rights reserved.
