Protein carbonylation modification is an irreversible post-translational modification (PTM) that plays a vital role in modulating protein function. The profiling of intracellular protein carbonylation can provide important information for the investigation of the molecular mechanisms of oxidative stress-related protein signaling networks and pathologies of related diseases. Here, we provide a meticulous description and systematic synthesis of recent research progress in protein carbonylation profiling assays development, especially for mass spectrometry-based chemoproteomic platforms for global profiling of protein lipoxidation. Oxidative stress has been regarded as the result of intracellular reactive oxygen species (ROS) exceeding the buffering capacity of antioxidant defenses, triggering oxidative damage towards lipids, DNA, and proteins. Protein carbonylation (PCO) can be produced either directly by amino acid side chain oxidation, protein backbone cleavage pathways, or indirectly via the formation of adducts between protein nucleophilic side chains and lipid peroxidation products or glycosylation products. We focus on the analysis and detection of protein carbonylation caused by lipid-derived electrophiles (LDEs), and highlight the recent development of protein LDEs profiling assays, especially for mass spectrometry (MS)-based chemoproteomic strategies. Due to the low relative abundance, poor chemical stability, and lack of specific physicochemical properties (e.g. absorption or fluorescence), many carbonylated proteins could not be detected directly, and their detection and quantification rely on the recognition with specific chemical probes. With these probes, mass spectrometry-based chemo-proteomic platforms emerge as powerful tools for comprehensive profiling of protein carbonylation, offering unparalleled sensitivity and specificity, facilitating the identification of protein targets and modification sites critical for elucidating the molecular mechanisms underlying disease progression.

The origin of homochirality in biomolecules is a pivotal issue in the origin of life field. It is central to our comprehension of the nature of life itself. Homochirality, a term describing the occurrence of molecules in specific chiral forms in three-dimensional space, is fundamental to biological activity. This concept is essential because the chirality of molecules impacts how they interact with one another and how they function within biological systems. Understanding the origin of homochirality not only illuminates the process of symmetry breaking in nature but also has significant implications for various areas within the life sciences.Recent years have witnessed extensive and profound developments in the field of the origin of homochirality. These studies have employed a combination of theoretical deduction, computational simulations, and experimental observations to explore this topic. This review provides a comprehensive review of current knowledge regarding the origin of biomolecular homochirality by examining three key aspects: the emergence of molecular chirality, the amplification, and the propagation of homochirality.Firstly, the emergence of homochirality in biological molecules is a crucial focus. Researchers investigate how and why certain chiral forms become predominant in nature. Secondly, the amplification of homochirality explores how initially minor chiral bias can be amplified to achieve a predominance of one chiral form over another. Finally, the propagation of homochirality involves studying how chiral properties flow through biological molecules and systems and are inherited through generations.By delving into these aspects, this review offers fresh perspectives and insights into the complex issue of homochirality. These insights will not only deepen our understanding of the intricate processes involved in the Origins of Life but also drive advancements in practical applications such as the development of chiral drugs, the design of chiral catalysts, and the synthesis of artificial lives.

All-solid-state batteries have the characteristics of high energy density, long cycle lifeand high safety, which is the development direction of the next generation of electrochemical energy storage. Solid-state electrolytes are the core components of all-solid-state batteries, and sulfide electrolytes have attracted extensive attention due to their advantages of high ionic conductivity and good mechanical ductility. As one of the most studied sulfide electrolytes in recent years, lithium-phosphorus-sulfur-chloride sulfide (LPSC) has high ionic conductivity and relatively low cost, but its practical application is limited by shortcomings such as poor stability and poor compatibility of positive and negative electrode materials. The composite solid-state electrolyte has good electrochemical and mechanical properties, and the composite solid-state electrolyte is prepared by modifying the LPSC with polymers, aiming to improve the interfacial compatibility and electrochemical stability of the LPSC. In this paper, the basic composition, recombination mode, modification strategy and ion transport mechanism of LPSC composite solid electrolyte are reviewed, and the future research direction and application prospect of LPSC composite electrolyte are prospected.

As a globally strategic resource, lithium resources are crucial for the development of new energy sources. Due to the similar physical and chemical properties of lithium and magnesium, lithium extraction from saline lakes with high Mg/Li ratios is a great challenge. Therefore, it is of great significance to reverse customize nanofiltration (NF) membranes with high performance according to targeted applications. This article discusses the separation mechanisms such as size exclusion, dehydration effect, Donnan effect, and dielectric exclusion, guiding composite film creation for excellent Li⁺/Mg²⁺ sieving from a theoretical direction. Besides, based on the above separation mechanisms, this paper first comprehensively summarizes existing models (non-equilibrium thermodynamic model, charge model, steric hindrance pore model, etc.) for evaluating composite film parameters, which effectively reduces the number of experiments for the preparation of high-performance NF film in the early stage. Finally, we discuss the importance of utilizing the synergy of principles and models to jointly guide the construction of NF membranes that can effectively separate Li⁺/Mg²⁺ and point out that in the future, the structural parameters of the customized NF membranes should be more precise, and the construction of the separation models should be more relevant to the real scenario, so as to better guide the synthesis of NF films with superior separation performance.

Protein chemical synthesis plays a crucial role in preparing proteins with specific sequences. Although this technology has been successfully applied to the synthesis of various proteins, the issues of solubility and refolding efficiency remain significant challenges for researchers when synthesizing hydrophobic and disulfide-rich proteins. The introduction of reversible chemical modification tags to the side chains or backbone of proteins offers an effective solution. Specifically, the introduction of solubilizing-tag during the protein synthesis process can significantly improve the water solubility of hydrophobic peptide segments, thereby facilitating subsequent protein synthesis and purification. The introduction of glycosylation modification effectively improves the folding of disulfide-rich proteins by stabilization of their folding intermediates. Moreover, these reversible modification tags can ultimately be removed by specific chemical or biological conditions, ensuring that the biological activity and structural integrity of the proteins are unaffected. This review delves into the types, introduction strategies and removal conditions of reversible modification tags and details their important applications in protein synthesis. These strategies not only expand the tools of protein chemical synthesis but also provide strong support for biomedical research and drug development, promising to drive further development in related fields.

Lithium metal batteries (LMBs) have attracted significant attention due to their remarkable energy density. Yet, challenges surrounding safety and cycling stability have existed as crucial factors impeding their practical application. The development of an efficient electrolyte, which stands as a vital component in LMBs, serves as a key strategy to tackle those issues. In this review, the fluorinated solvent for lithium metal batteries is summarized in detail for the follow three reasons: (1) because of the strong electron-withdrawing effect of fluorine atoms, the fluorination of electrolyte solvents can reduce the HOMO and LUMO energy level, facilitating the generation of a robust solid electrolyte interface layer enriched with LiF on the lithium metal anode's surface; (2) fluorination can alter the electrostatic potential distribution of electrolyte solvents, thereby modifying coordination sites and regulating solvation structures; (3) the fluorination of solvents can also enhance the temperature endurance and flame retardance of the electrolyte. According to the chemical structures, fluorinated carbonates, fluorinated ethers, fluorinated carboxylates, fluorinated siloxanes, and fluorinated nitriles are elucidated elaborately based on the degree of fluorination and position of fluorine substitution. The relationships between the chemical structures of fluorinated solvents and the solvation structure, interfacial compatibility, and cell performances are described systematically. This review summarizes and provides insights into the future development prospects on fluorinated solvents for lithium metal batteries.
