Summary: Deciphering signaling pathways driving plant adaptation to drought, changes in water availability, and salt in the context of climate change is crucial. In this study, the effect of different osmotic treatments on the roots of Arabidopsis plants was investigated. Transcriptome analyses revealed specific and quantitative responses to osmotic and turgor pressure variations, highlighting the role of water-related biophysical parameters in shaping the root transcriptome under stress.

Summary: The ternary system water-ethylene glycol-dimethyl sulfoxide (H2O-EG-DMSO) was studied using differential scanning calorimetry in the temperature range of 188-298 K. Significant supercooling in the solution within a specific concentration range is explained by the spatial networks of H2O and EG.

Summary: In recent years, the use of constant volume cryopreservation in medicine and biotechnology has gained attention. This study provides experimental results on the temperature-pressure-molar concentration correlation for commonly used cryoprotectants in isobaric cryopreservation. It also reveals thermodynamic data for cryoprotectants in isochoric freezing. These findings are important for developing new isochoric cryopreservation protocols.

Summary: A high-performance InNi3C0.5/Ni-foam catalyst has been developed for the gas-phase hydrogenation of dimethyl oxalate (DMO) to ethylene glycol (EG). The catalyst exhibits a high turnover frequency of 636 h(-1) and effectively activates DMO while hindering over-hydrogenation of EG to ethanol. This catalyst shows promising potential for industrial applications with full DMO conversion and high EG selectivity.

Summary: This study highlights the importance of assessing sperm quality and developing a cryopreservation strategy for the spotted scat due to limited male population. Several cryoprotectants were screened and the combination of DMSO (5%) + EG (5%) showed the best results in terms of motility, viability, and morphology of post-thaw cryopreserved sperm. This protocol can be used for the long-term preservation of sperm in captive breeding programs.

Summary: Recycling toxic ethylene glycol (EG) solutions is crucial for saving costs and preventing environmental hazards. Electrodialysis (ED) with a modified cation exchange membrane (CEM) was used to remove salts from high-saline EG wastewater. The modified CEM significantly reduced the leakage of EG, providing new insights for the desalination of EG solutions.

Summary: Despite progress in coal-to-ethylene glycol technology, the obtained products differ from those produced by petroleum methods. Improving the thermodynamic performance of the system is important, and this study estimated thermodynamic data using the Benson group contribution method and calculated the values of reaction enthalpy, Gibbs free energy, and equilibrium constant in the system. Temperature was found to influence the production of dimethyl carbonate (DMC) in the dimethyl oxalate (DMO) synthesis reaction, and the DMC content affected the spontaneous formation of ethylene carbonate (EC) in the DMO hydrogenation reaction. The results showed that higher temperatures favored DMC generation, and certain limits on DMC content were identified.

Summary: Noble metal-free hydroxyapatite/graphite composite catalysts with transition metal nanoparticles were used for the hydrogenation reaction of dimethyl oxalate. CoCu/HAp/G exhibited the highest methyl glycolate selectivity of 99.3%. The increase of experimentally measured work function values was found to improve the turnover frequency and selectivity, and Cu+ ions played a role in maintaining the stability of selectivity with increasing reaction temperatures.
