High-pressure high-temperature synthesis of NdRe.

In this study, we report the synthesis of a new cubic neodymium-rhenium metallic alloy NdRe through the utilization of high pressure and laser heating in a diamond anvil cell. NdRe crystallizes in the space group with a lattice parameter equal to 7.486 (2) Å and Z = 8 at 24 (1) GPa and 2,200 (100) K.

An examination of differences in epigenetic methylation of saliva type samples based on collection method.

In the context of forensic casework, it is imperative to both establish a DNA profile from biological specimens and accurately identify the specific bodily fluid source. To achieve this, DNA methylation markers have been developed for the differentiation of blood, semen, vaginal epithelial secretions, and saliva samples. Saliva, alternatively referred to as oral fluid, is recognized for its heterogeneous cellular composition, characterized by a mixture of epithelial, leukocytic, and bacterial cells.

The synthesis of novel lanthanum hydroxyborate at extreme conditions.

The novel structure of lanthanum hydroxyborate LaBO(OH) was synthesized by the reaction of partially hydrolyzed lanthanum and boron oxide in a diamond anvil cell under high-pressure/high-temperature (HPHT) conditions of 30 GPa and ∼2,400 K. The single-crystal X-ray structure determination of the lanthanum hydroxyborate revealed: , = 6.555(2) Å, = 17.
