Summary: A series of NaYF4:Yb3+, Tm3+@NaYF4:Yb3+, Er3+ core@shell nanocrystals with different sensitizer contents were synthesized to investigate the impact of sensitizer Yb3+ on upconversion luminescence. The results showed that as the Yb3+ content increased, the green upconversion luminescence decayed faster than the red, and the red to green upconversion luminescence ratio significantly increased in samples highly doped with Yb3+.

Summary: In this paper, the red-to-green emission ratio of NaYF4:Er3+/Yb3+ phosphors was adjusted through power density, pulse width, and frequency. It was found that the ratio increased with the increase of power density, pulse width, and frequency. The effect of power density on the ratio was not significant due to the combined effect of two-photon up-conversion processes and nonradiative relaxation process H-2(11/2)/S-4(3/2) -> F-4(9/2) (Er3+). The changes in ratio caused by pulse width and frequency were attributed to different non-steady-state up-conversion processes of red and green emissions.

Summary: Anisotropic rare earth ion (RE3+) doped fluoride upconversion particles have great potential in various fields, and a facile strategy to synthesize the particles was developed in this study. By controlling the synthesis time, NaYF4: Yb, Gd, Er, and NaYF4: Yb, Gd, Tm upconversion nanorods were successfully synthesized via microwave synthesis route, and their optical properties were compared with those prepared via solvothermal technique. The phase and morphology of the particles were found to change with the increase in synthesis time. Surface modification of the particles transformed their hydrophobicity to hydrophilicity, and the surface modification route influenced the upconversion luminescence and solvent-dependent emission properties. Furthermore, the laser power dependent studies revealed that the upconversion process is a multi-photon process.

Summary: We investigated the impact of methane seepage on the pore fluid and methane-derived authigenic carbonate (MDAC) chemistry in the ARAON Mounds in the Chukchi Sea. Our findings show that the high methane flux and related byproducts significantly alter the fluid chemistry and physical properties of the sediment columns. This research improves our understanding and prediction of pore fluid and MDAC chemistry in the Arctic Ocean, particularly in relation to methane seepage caused by global climate change.

Summary: The warming of the Arctic Ocean affects the input of dissolved organic matter (DOM) into the region, which in turn impacts the bacterial communities. Changes in DOM inputs alter the abundance, size, metabolism, and composition of Arctic bacteria. The increase in DOM fluxes and the diversification of DOM composition due to climate warming lead to enhanced CO2 emissions and the emergence of replacement bacterial communities in the Arctic Ocean.

Summary: Interactions between chemodiverse dissolved organic matter (DOM) and biodiverse microbes are influenced by numerous intrinsic and extrinsic factors, which are still not well understood. This study provides a comprehensive update and bridging of the interdisciplinary theme. Different ecosystems, such as algal-dominated aquatic ecosystems and ecosystems supplied by soil and vascular plants, have different types of DOM and microbial communities. Various microorganisms show evidence of being able to process different types of organics, but the chemical structure and bonds of the organics vary. Both intrinsic factors (such as DOM composition and structure) and extrinsic factors (such as sunlight and dissolved oxygen) play important roles in the interactions between DOM and microbes.

Summary: This study found that MoPtc1 and MoPtc2 in the rice blast fungus Magnaporthe oryzae are induced by calcium chloride and play a role in regulating MAPK signaling pathways. MoPtc1 is recruited by the adaptor protein MoNbp2 to deactivate Osm1 under hypoosmotic conditions. Additionally, MoPtc1 and MoPtc2 are localized in different cellular compartments during fungal development.

Summary: The associations of organic matter (OM) with iron (Fe) and phosphorus (P) differ between algae-dominated and macrophyte-dominated zones in shallow lakes, as a result of different sources and compositions of organic matter. The OM-Fe-P associations in the macrophyte-dominated zone have a higher C/Fe ratio and a lower P/Fe ratio compared to the algae-dominated zone. This is attributed to the higher production of aromatic organic matter from macrophytes, resulting in more resistant OM-Fe-P associations and lower internal loading of P in the macrophyte-dominated zone.

Summary: Alpine lake habitats are transforming into subalpine lakes due to climate change, resulting in increased vegetation. The introduction of terrestrial dissolved organic matter (TDOM) from watershed soil into subalpine lakes undergoes photochemical reactions and can alter the composition of dissolved organic matter (DOM) and affect bacterial communities. In this study, Lake Tiancai was chosen as a typical subalpine lake to investigate the transformation of TDOM through photochemical and microbial processes. The results showed that both processes caused a decrease in dissolved organic carbon and light-absorbing components over 107 days, with the photochemical process promoting chemodiversity. The microbial process had a smaller impact on TDOM transformation compared to the photochemical process. It was also found that light promoted the production of certain molecules associated with Bacteroidota, suggesting a potential influence on bacterial communities. Carboxylic-rich alicyclic molecules were generated in both processes, indicating the conversion of TDOM into a stable pool over time. This study provides insights into the response of high-altitude lakes to climate change in terms of the carbon cycle and lake system structure.
