    Abstract: While metal carboxylates are by no means rare or inaccessible, complete characterization with notable exception of acetates is largely neglected hence a deficiency within the carboxylate literature giving rise to discrepancies within the characterization data available thus, spectroscopic properties of synthesized sodium metal carboxylates of aceti...

    Abstract: Authentication of coins is frequently presenting complicated problem in numismatics practice. Metal composition only may not be enough to identify forgeries, notably when one deals with noble metals – silver, gold or electron. Isotopic ratios, providing in certain cases information regarding metallic ore source (geographical provenance), require a ... Show More
