Summary: This study aimed to investigate the reliability of Delta-Delta PCO2 and Delta ScvO(2) in defining fluid responsiveness in septic patients undergoing volume expansion (VE). The results showed that these parameters were significantly correlated with changes in CI after VE and could predict fluid responsiveness effectively.

Summary: Solid-state NMR is used to generate CO2 adsorption isotherms, allowing the differentiation between chemi- and physisorbed components and investigation of their respective adsorption mechanisms. The proposed method is validated by comparing with volumetric measurements, and the obtained isotherm curves provide advanced analysis of the sorbents.

Summary: This article reports on the development of a new Rh-Ru cocatalyst decorated on an alkaline earth-doped NaTaO3 surface for photocatalytic CO2 reduction to produce CH4 using water as an electron donor. The researchers achieved about 10% selectivity (electronic efficiency) for CH4 formation under ambient conditions, accompanied by O2 evolution as the oxidation product of H2O.

Summary: This study found that photosynthesis, respiration, and organic matter degradation were the main driving mechanisms of CO2 absorption and release in Lake Poyang. The water-level fluctuations inherent to floodplain-lakes may also have an impact on C cycling processes and CO2 exchange rates.

Summary: In this study, the minimum miscible pressure (MMP) between crude oil and CO2 system in the study area was predicted to be 29.6 MPa using a long-slim-tube displacement experiment method, which helps realize miscible flooding in ultra-low permeability reservoirs and enhance oil recovery.

Summary: This paper studies the feasibility and optimization parameters of nitrogen injection development of fractured reservoirs through experiments, showing that nitrogen injection can increase early production but gas channeling needs to be avoided. Gas-water alternate flooding can reduce injection pressure and improve recovery.

Summary: This study used molecular dynamics simulations to investigate the microscopic process of CO2 injection into shale nanopores with a coexistence of oil and water bridges. The results confirmed that CO2 can break through water bridges in shale nanopores to improve the mobility and recovery of crude oil. Four major mechanisms of CO2 breaking through water bridges were summarized. The research also emphasized the importance of proper regulation of CO2 injection and shut-in to avoid reinjection of recovered oil.

Summary: This study reports the development of an image-free ultrasound device - ARTSENS Plus - that can measure various vascular health markers, including local and regional arterial stiffness, central and peripheral blood pressure, and vessel dimensions, in one examination. The device's functionality and accuracy were validated through a preclinical study, demonstrating its ability to perform reliable evaluations of vascular health.

Summary: This review introduces two extremely important technologies, atmospheric pressure CO2-based modified atmosphere packaging (MAP) and high pressure CO2 non-thermal pasteurization (HPCD), for controlling microorganisms. CO2-based MAP delays the growth of microorganisms by replacing the surrounding air, while HPCD achieves sterilization using subcritical or supercritical CO2. However, there are still challenges to overcome in both technologies. The action mechanism of CO2 on microorganisms, including the changes in pH, proteins, enzymes, and cell membrane, needs further exploration.

Summary: Ophicarbonates play an important role in the recycling of CO2 and H2O between Earth's surface and interior. Laboratory experiments show that ophicarbonates can coexist with melt under certain conditions, and the amount of CO2 released or retained during subduction depends on the temperature and pressure conditions. Comparing with the P-T paths of subducting slabs, it is found that significant amounts of CO2 will be released in hot subduction zones, while significant amounts of CO2 will be retained in cold subduction zones. In ancient subduction zones, ophicarbonates may have been more significant in deep carbon fluxes.
