Summary: Through stable isotope analysis, this study identified sea cucumber as the most important extractive co-cultured species in the IMTA system, followed by suspension-feeding bivalves, with cultured seaweeds having the least impact on waste reduction. The lack of isotopic consistency between IMTA and control feeders suggests minimal contribution of aquaculture waste to the neighboring coastal environment.

Summary: This study reveals past regional ice-mass changes near Petermann Glacier in NW Greenland through relative sea level data obtained from marine bivalves. The research found that there was ice loss at Petermann Glacier at or before 9,000 years ago, followed by further mass loss around 6,000 years ago. The study speculates that regional ice caps regrew during the mid-Holocene in response to cooling and increased precipitation.

Summary: This study investigated the effects of vanadium on sea urchin embryo development and proteolytic activity of gelatinases. The results showed that vanadium exposure caused morphological aberrations, reduced embryonic cell distribution, and altered embryo volume. Additionally, vanadium affected the expression and activity of gelatinases, particularly MMP-14. These findings suggest that an integrated approach combining morphology, proteolytic activity, and MMP-14 expression is important for studying the effects of vanadium.

Summary: The warming in the Antarctic Peninsula is causing significant impacts on the cryosphere and ecosystems. The coastal systems are highly diverse and influenced by Antarctic seaweeds and bird colonies. Laboratory experiments showed that different leachates from seaweeds and penguin guano had either suppressing or enhancing effects on aerosol particle production, with the guano leachate resulting in high ice nucleating particles. Further studies on ocean-atmosphere coupling are needed to understand the poorly understood climate feedback processes.

Summary: The spatial distribution and energy spectrum of neutron yield were investigated using neutron activation analysis and MCNP simulation, with results extended to a 3D mapping of neutron yield distribution in KSTAR. The analysis showed significant differences in neutron yields between the inner and outer vessel of KSTAR, with a decrease in neutron yield proximity to the vacuum vessel wall.

Summary: A study conducted in 2019 investigated the presence of organotin pollution in components of benthic ecosystems in the Barents Sea and the Fram Strait. The results showed moderate contamination of the studied samples with organotin compounds, with the highest concentrations found in sediment samples. The study also revealed active transformation of organotin compounds in sediment and algae, with accumulation in the soft tissues of molluscs.

Summary: The co-contamination of NO3 and V(V) is a serious environmental issue, for which the understanding of degradation pathways and electron competition sequence is limited. This study found that vanadium leads to the accumulation of NO and N2O, while NO3 and NO2 promote vanadium activation. The carbon metabolism analysis revealed that glycolysis, pentose phosphate, and TCA cycle pathways provide sufficient energy for pollutants reduction.

Summary: The study of Bitlis ignimbrites in eastern Turkey revealed different mineral compositions and color changes in black, red, and grey levels. Utilizing Neutron Activation Analysis and Confocal Raman spectrometr methods, distinctive features and compositions were determined, including an abundance of Fe-Ti oxides and hydroxides in intermediate levels. Additionally, the Raman spectroscopy method identified the presence of fayalite and provided insights into the mineralogy and composition of the ignimbrites.

Summary: This study analyzed the bioaccumulation of 13 heavy metals in 11 different seaweed species. The results showed that different seaweed species had varying capacities for heavy metal bioaccumulation. The study also revealed that the consumption of certain seaweed species may pose a moderate to high health risk for children. Additionally, the study identified As and Cr as the limiting factors for seaweed consumption.

Summary: George Hevesy and Hilde Levi are well-known as the original discoverers of neutron activation analysis. However, there were many other researchers in Europe who, knowingly or unknowingly, discovered neutrons and conducted experiments on neutron-induced radioactivity. This synopsis provides a historical timeline of several parallel experiments that took place in a very short period of time. Eventually, it was Hevesy and Hilde who first used the powerful technique of neutron activation analysis in the field of analytical chemistry.

Summary: In this study, the phase evolution and reactions of vanadium hexacyanoferrate (VHCF) cathode in aqueous Zn-ion battery were investigated. The results revealed that VHCF electrode was gradually converted into zinc hexacyanoferrate and vanadium oxides (VOx) through multiple charge-discharge cycles. The redox behavior of VOx enhanced the specific capacity of the electrode. In addition, the presence of decavanadate anion, the intermediate of VHCF transformation, during electrochemical reaction was confirmed.

Summary: An instrumental neutron activation analysis method combined with Compton suppression spectrometry was developed for the simultaneous determination of Cl, Br, and I in salmon muscle and skin at nanogram levels. The extraction of organohalogens in lipids was optimized using different solvent systems, and an acetone-hexane (1:1) system was selected for its high efficiency and low contamination. The study also included the development of lipid fractionation procedures and characterization techniques using nuclear magnetic resonance and mass spectrometry. Results showed high levels of triacylglycerols in both muscle and skin.
