Summary: The reaction pathways and potential energy profiles of the reaction between methyl formate (MF, HC(O)OCH3) and NO2 were theoretically explored, and the temperature- and pressure-dependent rate constants were calculated. The results showed that the reaction pathways are pressure independent, and the H-abstraction channel is more favored. The detailed reaction kinetics in this study will be helpful for the development of kinetic models for other ester-based fuels.

Summary: The hydrogen bond formed between water molecules and oxygen functional groups is crucial for the moisture content of lignite. Deep eutectic solvent (DES) with abundant hydrogen bond acceptors and donors is employed to enhance the removal of moisture in lignite. The DES-assisted hydrothermal treatment (DES-HT) has higher dehydration efficiency than the conventional method, leading to a more effective removal of both total moisture content and molecular water content in lignite.

Summary: The rapid economic growth leads to increased demand for energy, resulting in resource scarcity and environmental pollution caused by fossil fuel combustion. Electrochemical energy conversion and storage techniques such as rechargeable batteries, fuel cells, and water electrolysis offer promising solutions to these issues. However, improving their electrochemical performance is still challenging due to limited understanding of their reaction mechanisms. Therefore, in situ tracking and capturing intermediates for mechanism verification is significant.

Summary: A deep eutectic solvent (DES) synthesized by ChCl and ZnCl2 was used to improve hydrothermal dewatering (HD) by reducing moisture and oxygen content in lignite. The combustion performance of upgraded coals was greatly influenced by changes in physicochemical structure. Thermogravimetric analysis was conducted to investigate the effects of DES addition, upgrading temperature, and the molar ratio of ChCl and ZnCl2 on combustion performance. The results showed that DES addition shifted and delayed the combustion curves towards higher temperatures, indicating improved combustion reactivity and reduced spontaneous combustion tendency.

Summary: Modulating functional groups on molecules can achieve novel electron transport properties in single-molecule electronics. In this work, viologen derivatives with three attached organic radicals including sp2 hybridized O•, NH•, and CH2• are studied for their spin transport properties. The results show excellent spin filtering efficiency (SFE) with α spin conductance being about 100 times larger than β spin conductance within a low-bias window. The findings also demonstrate the tunability of SFE by altering alkyl chain length and applied bias, providing a new strategy for developing viologen-based radical systems as single-molecule spin switches.

Summary: This study investigates the normal Raman spectra and surface-enhanced Raman spectra (SERS) of aniline molecules adsorbed on silver electrodes. Anharmonic effects and the coupling effect between vibrational modes are considered. The results demonstrate that the amino wagging vibrational mode plays a significant role in the anharmonic Raman spectra. The excited state energy gap and pre-resonance Raman spectra of aniline-silver cluster complexes are also examined, suggesting a potential charge-transfer enhancement mechanism.

Summary: Surface-enhanced Raman spectroscopy (SERS) is widely usedfor efficient identification and characterization of DNA structures. The SERS signals of the adenine group show high detection sensitivity in various biomolecular systems. However, there is still no consensus on the interpretation of certain types of SERS signals of adenine and its derivatives on silver colloids and electrodes. This study introduces a new photochemical azo coupling reaction for adenyl residues, which selectively oxidizes adenine to azopurine in the presence of silver ions, silver colloids, and nanostructured electrodes under visible light irradiation. The resulting azopurine is found to be responsible for the SERS signals. This photoelectrochemical oxidative coupling reaction is facilitated by plasmon-mediated hot holes and regulated by positive potentials and solution pH, providing new insights into the study of azo coupling in the photoelectrochemistry of adenine-containing biomolecules on plasmonic metal nanostructure electrodes.

Summary: Abuse of dopings is a serious issue in competitive sports globally. Traditional doping detection methods are costly, bulky, and time-consuming. This study proposed a strategy using liquid phase extraction and surface-enhanced Raman spectroscopy for ultrasensitive and quick detection of multiple dopings. The method successfully detected four dopings in human saliva and urine, with detection limits ranging from 5 to 50 ng/mL. The synchronous detection of dopings at a concentration of 100 ng/mL in saliva and urine was achieved within one minute. This strategy demonstrates the advantages of SERS in on-site and rapid detection of multiple drugs.
