Integrating intermittent ultrasound with micro-nanobubbles for enhanced reduction of pathogenic bacteria during fresh-cut lotus root sanitation.

Drained agricultural peatlands are significant sources of greenhouse gas (GHG) emissions, particularly carbon dioxide (CO₂) and nitrous oxide (N₂O). Peat thickness typically varies widely between sites due to cultivation history, but its effect on soil conditions, plant growth, and GHG emissions are poorly understood and seldom considered in national GHG inventories and emission mitigation strategies. Here, we present a three-year study of a drained agricultural peatland in northern Finland, with peat depth ranging from 20 to 80 cm. We measured soil properties, plant growth and GHG fluxes, to evaluate how peat depth influences ecosystem processes and emissions. Plots with deeper peat exhibited more stable and shallow water table depth (WTD), and had higher peaks in soil nitrate concentrations, but these differences did not result in significant changes in soil moisture, plant growth, or GHG fluxes. However, we observed periods when drier conditions in mull soil limited ecosystem respiration (R e ), while WTD indicated a stronger negative effect on R e and a positive effect on CH₄ fluxes in plots with deeper peat layer. Our results suggest that peat depth alone does not improve GHG inventories since shallow-peated drained peatlands can have as high GHG emissions as the thicker ones, and hydrological parameters should be prioritized instead. However, mitigation measures such as rewetting can still be targeted towards fields with thicker peat layer, as larger soil organic carbon stocks can be affected, and rewetting is likely easier due to more stable WTD and higher water holding capacity. • Three-year study on Finnish agricultural peatland explores GHG fluxes across peat depths. • Nitrate concentrations were positively correlated with peat depth. • Water table dynamics differed between shallow and deep peat soils. • Peat depth did not significantly affect soil moisture, plant growth or GHG fluxes. • Categorizing peatlands by depth may not improve accuracy of GHG inventories.

• Sustainable aviation fuels are critical for reducing CO 2 emissions. • Limonene exhibits combustion properties similar to Jet A-1. • Laminar burning velocities measured at 1 bar and 358–438 K. • Tests included limonene, MURI 1 surrogate, and a 70/30 blend. • Pure limonene reached LBV of 70 cm/s, exceeding kerosene. Sustainable aviation fuels (SAFs) are a critical pathway for reducing carbon dioxide (CO 2 ) emissions from the aviation sector, yet the deployment of new SAF candidates requires a robust understanding of their fundamental combustion behavior. Limonene, a renewable terpene derived from pine and citrus biomass, has emerged as a promising candidate due to its favorable energy content and bulk properties relative to conventional Jet A-1. However, despite increasing interest, fundamental premixed combustion data for limonene—particularly laminar burning velocity and flame stability parameters—remain limited. The aim of this study is to address this gap through an experimental investigation of the premixed combustion characteristics of limonene. Laminar burning velocity measurements were performed in spherical and cylindrical constant-volume reactors at atmospheric pressure and unburned-gas temperatures of 358, 398, and 438 K using Schlieren imaging. Experiments were conducted for pure limonene, the Jet A-1 surrogate fuel MURI-1, and a 70/30 (vol./vol.) MURI-1–limonene blend over equivalence ratios from 0.7 to 1.4. The results show that pure limonene exhibits high laminar burning velocities, reaching peak values of approximately 70 cm s⁻ 1 , exceeding those of conventional kerosene surrogates. Flame stability analysis reveals that limonene flames become increasingly sensitive to stretch under fuel-rich conditions, as indicated by decreasing Markstein length and Lewis number. Blending limonene with MURI-1 yields intermediate burning velocities and improves flame stability through increased Markstein length, despite a modest reduction in flame thickness, with enhancements of up to 8% observed under rich conditions. These findings provide new fundamental combustion data for limonene and demonstrate combustion trends consistent with other SAF candidates, supporting its potential as a viable component for future ASTM-certified sustainable aviation fuel formulations and for the development of validated chemical-kinetic models.

Xenon is reemerging as a clinically attractive inhalational anesthetic because it combines rapid kinetics and cardiovascular stability with mechanism features that differ from GABAergic agents. Simultaneously, new membrane-biophysics and systems-neuroscience data are reshaping how models in anesthetic state transitions worked, which expands the future of how anesthetic agents are used. Contemporary work strengthens the view that xenon acts primarily via noncompetitive NMDA receptor inhibition, with additional effects on excitability-related ion channels. Whole-cortex modeling and high-density electroencephalogram studies link xenon sedation to reduced long-range coupling, slowed alpha peak frequency, increased damping of alpha-band dynamics, and a shift toward more stable population dynamics that track response better than gas concentration. Despite this, xenon's studies do not show a consistent reduction in postoperative neurocognitive disorders. However, xenon has been shown to accelerate early recovery anesthesia times. Though definitive outcome benefits remain unproven, xenon's value may represent a reemergent inhalational drug as the environmental carbon dioxide footprint is very attractive. Besides, the rapid recovery of xenon's general anesthesia, is also a distinct, quantifiable systems-level physiology that can guide depth monitoring and motivate targeted trials, improving the design and protocol of the studies in high-risk neurocognitive and brain-injury settings.

• Bespoke VLE apparatus designed for CO 2 solubility in amino acid salt solutions • CO 2 solubility in aqueous potassium glycinate up to T = 393 K at p ≤ 0.7 MPa • Density measurements for solvent up to T = 393 K at p ≤ 0.7 MPa with CO 2 loading • Glycine salts exhibit higher molar CO 2 uptake than MEA We report measurements of the solubility of CO 2 in aqueous potassium glycinate and of the density of the solution with and without CO 2 loading. The CO 2 solubility was measured with a bespoke static-synthetic vapour liquid equilibrium (VLE) apparatus, while densities were measured with a high-pressure vibrating-tube densimeter. The VLE apparatus was validated by means of measuring the solubility of CO 2 in a 7 mol·kg -1 aqueous ethanolamine solution, and the results were in good agreement with the literature. Three molalities of aqueous potassium glycinate were studied: (1, 2 and 3) mol·kg -1 . The CO 2 solubility measurements were made at temperatures between (313.15 and 393.15) K with pressures up to 0.65 MPa, while the density was measured at temperatures between (298.15 and 393.15) K with pressures up to 10 MPa.
