Abstract: Using a synchrotron radiation source and a diamond anvil cell, we measured the pressure dependence of the lattice parameters of a polycrystalline Ti3GeC2 sample up to a pressure of 51GPa. No phase transformations were observed. Like Ti3SiC2, and most other compounds belonging to the same family of ternary carbides and nitrides, the so-called MAX phases, the compressibility of Ti3GeC2 along the c axis is greater than that along the a axis. The bulk modulus is 197±4GPa, with a pressure derivative of 3.4±0.1. We also characterized Ti3GeC2 by infrared spectroscopy; four of the five expected infrared modes were observed for this material.

Abstract: A new route to 15-hydroxydehydroabietic acid derivatives from abietic acid ( 11 ), via abieta-8,13(15)-dien-18-oic acid ( 12 ), is reported. Utilizing this, the first synthesis of bioactive terpenes 3 , 6 , 9 and 10 , as well as natural diol 4 and lactones 7–8 was achieved. [Copyright &y& Elsevier]
