Very long chain-saturated and-polyunsaturated fatty acids(VLC-SFA and VLC-PUFA, respectively) are a functionally important class of fatty acids containing 28 carbons or more in their acyl chain. They are synthesized by the elongation of very long fatty acids-4(ELOVL4) enzyme, expressed mainly in the brain, retina, skin, testes, and meibomian gland, where these fatty acids are found(Agbaga et al., 2008). Further, these organs exhibit tissuespecific VLC-PUFA and VLC-SFA biosynthesis and incorporation into complex lipids for specific functions. In the brain, skin, and Meibomian glands, the ELOVL4 mainly makes VLC-SFA, which are incorporated into complex sphingolipids. In the retina, the ELOVL4 makes VLC-PUFA that are incorporated into phosphatidylcholine, that are critical for visual function, while in testes and sperm, the VLC-PUFA are incorporated into sphingolipids that are critical for fertility(Yeboah et al., 2021). 展开更多

The electrocatalytic urea oxidation reaction(UOR)has emerged as an energy-efficient alternative to the traditional oxygen evolution reaction for hydrogen production,with mechanistic understanding being critical for the rational design of catalysts.This review systematically summarizes recent advances in in situ characterization techniques for elucidating the dynamic reaction mechanisms of UOR.Studies reveal that phase transitions,valence state migration,and electronic structure evolution of catalysts under operational conditions are key factors governing activity and stability.Techniques such as in situ X-ray diffraction,X-ray absorption spectroscopy,Raman spectroscopy,and Fourier-transform infrared spectroscopy enable real-time monitoring of catalyst reconstruction,intermediate evolution,and interfacial adsorption behavior,overcoming the environmental deviations inherent in conventional ex situ characterization.When combined with theoretical calculations,these methods provide direct evidence for identifying active-site configurations,reaction pathways,and rate-determining steps.In addition,special emphasis is placed on multimodal in situ strategies for deciphering synergistic effects in nickel-based catalysts,while current challenges,including non-alkaline systems,real wastewater environments,and multi-metal cooperation mechanisms,are critically discussed.Future research should focus on developing novel in situ approaches for complex systems and establishing a mutually reinforcing framework integrating theoretical prediction and experimental validation,thereby advancing UOR catalyst design from empirical exploration to mechanism-guided optimization. 展开更多

The InSight mission has obtained seismic data from Mars,offering new insights into the planet’s internal structure and seismic activity.However,the raw data released to the public contain various sources of noise,such as ticks and glitches,which hamper further seismological studies.This paper presents step-by-step processing of InSight’s Very Broad Band seismic data,focusing on the suppression and removal of non-seismic noise.The processing stages include tick noise removal,glitch signal suppression,multicomponent synchronization,instrument response correction,and rotation of orthogonal components.The processed datasets and associated codes are openly accessible and will support ongoing efforts to explore the geophysical properties of Mars and contribute to the broader field of planetary seismology. 展开更多

In recent years,with the increasing attention to issues related to carbon emissions,such as carbon tariffs and government netzero carbon emission policies,carbon emissions have become an important indicator that is being prioritized by governments worldwide.The Google Environmental Insights Explorer(EIE)tool has been developed to facilitate the collection and integration of data in this context.This study focuses on Tainan City and utilizes EIE to analyze greenhouse gas emissions from transportation.By using EIE,the study obtains data on greenhouse gas emissions from transportation activities in Tainan City.EIE utilizes data collected by Google and simulation functions to estimate data based on actual measurements of transportation activities.This tool saves time and resources by eliminating the need for on-site investigations while providing data that closely represent the real emissions from transportation activities in urban areas.Transportation vehicles contribute to greenhouse gas emissions in two ways:through direct combustion of fossil fuels and through the consumption of electricity in electric vehicles(EVs).The level of greenhouse gas emissions in a city’s transportation industry depends on factors such as transportation modes,fuel types,fleet age and energy efficiency,total distance traveled,and annual mileage.EIE estimates the greenhouse gas emissions from Tainan City’s transportation industry in 2022 to be 3,320,000 metric tons,including emissions from buses,motorcycles,cars,walking,railways,bicycles,and other modes of transportation. 展开更多

Lithium-ion batteries are at the forefront of modern energy storage technology.However,the accumulation of by-products such as ethylene and carbon dioxide during charging and discharging cycles reduces battery effective capacity and threatens large-scale safe performance.With significant advantages over ethylene carbonate(EC)electrolytes,fluorinated electrolytes can more effectively suppress internal gas evolution,thereby improving battery safety and cycling stability.To reveal the mechanism behind gas formation in lithium-ion batteries,our study investigated the transport behavior and interfacial products of fluorinated electrolytes under various operation conditions,including electrode material and electrolyte composition.Innovatively,we applied the reaction network integrator ReacNetGenerator to the analysis of the solid electrolyte interface(SEI)in lithium batteries,providing more molecular fingerprint information from the perspective of specific products.Using reactive molecular dynamics(MD)simulations with the ReaxFF force field and EChemDID,complemented by density functional theory(DFT)calculations,our results demonstrate that fluorinated electrolytes can effectively suppress the decomposition of LiPF_(6) to produce toxic gases PFs and PF_3.DFT analysis further reveals that highly fluorinated solvents(e.g.,FEMC)enhance the anti-reduction stability of PF_(6)~-through synergistic regulation of molecular orbital energy levels,thermodynamic electron affinity,charge transfer,and electrostatic potential distribution,thereby mitigating LiPF_(6) decomposition.Additionally,fluorinated electrolytes generate significantly more LiF components than non-fluorinated ones to promote the formation of a stable and durable solid electrolyte interface(SEI).Experimental validations via XPS and GC-MS confirm reduced CO_(2) generation and LiF-enriched SEI formation,aligning with simulation and DFT data.The findings provide valuable insights for the design of advanced electrolytes aimed at ensuring large-scale,safe energy storage solutions. 展开更多
