Pivotal role of Tc NMR spectroscopy in solid-state and molecular chemistry.

The radioelement Technetium (element 43) pertains to various domains including the nuclear enterprise (i.e., spent nuclear fuel (SNF) reprocessing and nuclear waste remediation) and nuclear medicine (i.

Route to Stabilization of Nanotechnetium in an Amorphous Carbon Matrix: Preparative Methods, XAFS Evidence, and Electrochemical Studies.

Technetium-carbon nanophases are obtained by thermal decomposition of pertechnetates with large organic cations under an argon atmosphere. Parallel carbonization of organic cations (hexamethyleneiminium and triphenylguanidinium), which occurs during the thermal decomposition of their pertechnetates, leads to the formation of X-ray amorphous solid products. An X-ray absorption fine structure study revealed that they have a crystal structure containing technetium-carbon bonds with a length of 1.

New Preparative Approach to Purer Technetium-99 Samples-Tetramethylammonium Pertechnetate: Deep Understanding and Application of Crystal Structure, Solubility, and Its Conversion to Technetium Zero Valent Matrix.

Tc is one of the predominant fission products of U and an important component of nuclear industry wastes. The long half-life and specific activity of Tc (212,000 y, 0.63 GBq g) makes Tc a hazardous material.

CRISPR/Cas9-mediated gfp gene inactivation in Arabidopsis suspension cells.

Targeted genome editing using CRISPR/Cas9 is a promising technology successfully verified in various plant species; however, it has hardly been used in plant cell suspension cultures. Here, we describe a successful knockout of a green fluorescent protein (gfp) reporter gene in Arabidopsis cell culture. We transformed seven transgenic suspension cell lines carrying one to three gfp gene copies with a binary vector containing genes coding for Cas9 and guide RNAs targeting the gfp gene.
