Phase relations in the Ti-C-SiC system are studied with the aim of optimizing Ti3SiC2 synthesis. The optimal starting-mixture compositions for the synthesis of phase-pure Ti3SiC2 powder can be represented by the formula 3Ti + (1 − z)C + (1 + z)SiC, where z = 0.2–0.6. In the temperature range 1630–1670 K under dynamic vacuum, the excess silicon vaporizes from the sample. The processes

Silicon carbide (SiC, Sigma-Aldrich) particles of size 10–15 µm were dispersed in a glass chaer (0.3 m diameter and 0.6 m high) by blowing 1 g of SiC powder for 10 s at 300 kPa. After dispersion, the particles were allowed to settle on the sample mounted on a 45° tilted stage for 30 min.
Tedizolid (TR 700; Torezolid; DA-7157) is a novel oxazolidinone, acting through inhibition of bacterial protein synthesis by binding to 23S ribosomal RNA (rRNA) of the 50S subunit of the ribosome. - Mechanism of Action & Protocol.
For deuteration, the starting materials were either synthesized or purchased from Sigma-Aldrich. To prepare CD 3 ND 2 , methylamine anhydrous gas ≥98% was dissolved in D 2 O. The lead (II) acetate trihydrate (99%) was dissolved in D 2 O three times for an exchange reaction and subsequently dried in a vacuum oven for several hours.
