Synthesis and Structure Solution of Ba[SeCN]2

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The new quasi‐binary selenocyanate Ba[SeCN]2 was synthesized by the reaction of barium hydroxide with ammonium selenocyanate. Its crystal structure was determined from powder X‐ray diffraction (PXRD) data. Additionally, density functional theory (DFT) analysis and Raman spectroscopy were performed.

Phylogenetics and Biogeography of Cobra (Squamata: Naja) in Java, Sumatra, and Other Asian Region

open access: yesJournal of Experimental Life Science, 2017
The separation of Sumatra and Java occurred at the end of the Miocene (10 mya) to the end of Pliocene (1.8 mya). The existence of ecological variations and geographic barriers inhibits gene flow through the isolation of adaptation, geography ...

Longitudinal changes in peritoneal solute transport rate and the impact of lower glucose degradation product glucose dialysates

open access: yesTherapeutic Apheresis and Dialysis, Volume 29, Issue 3, Page 471-478, June 2025.
Abstract Introduction Peritoneal solute transfer rates (PSTR) are reported to increase with time. Changes in PSTR were reviewed in long‐term peritoneal dialysis (PD) patients to determine whether lower glucose degradation products (low GDP) dialysates prevented an increase in PSTR. Methods PSTR was determined with a 4‐h peritoneal equilibrium test with
