This growing interest stems from their tunable atomic structures, controlled stoichiometry, diverse coordination environments, enhanced orbital interactions, and high electronic and structural flexibility. Alloys are broadly classified into two categories: intermetallic compounds and solid-solutions based on their structure, phase and atomic arrangement. These structural characteristics play a pivotal role in determining electrochemical energy conversion performance. Consequently, compositionally engineered alloy nanostructures have emerged as promising candidates in this field. This review provides a detailed analysis of alloy-based electrocatalysts for energy conversion applications. We begin with a brief introduction to understanding hydrogen (H₂) production, associated problems and potential solutions. This is followed by an overview of alloys, intermetallic compounds and solid solutions, with emphasis on their structure and compositional features. Subsequently, we summarize recent advances in alloy catalysts in the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER). To reduce the cell voltage and enhance energy efficiency, the OER has been potentially replaced by alternative oxidation reactions including the urea oxidation reaction (UOR) and hydrazine oxidation reaction (HzOR), particularly in contaminate degradation assisted energy conversion systems. In the following section, we discuss solid solution and intermetallic compound catalysts for the HER, OER, OWS, UOR, and HzOR. We further compile and analyze the relationship between catalyst electronic structures, catalytic activity and reaction kinetics, highlighting how electronic modulation influences these energy systems. As a conclusion, we provide a summary of key insights, current challenges and future research directions for the advanced compositionally engineered metallic electrocatalysts. We anticipate that this review will provide valuable guidance to early career researchers and contribute to advancing electrocatalyst design toward the industrialization of energy conversion technologies and the development of sustainable green energy economy.</p>","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":" ","pages":""},"PeriodicalIF":4.3,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149177867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite its programmable, sequence-specific activity, uncontrolled or prolonged exposure to Cas9 can lead to severe genotoxicity, restricting its enormous clinical potential. To circumvent its non-specific and uncontrolled activities, Cas9 has been chemically modified for spatio-temporal and precision control. For developing such ChemComCas9, the WT Cas9 has been chemically modified using either its surface-exposed natural cysteine or by the installation of additional cysteine residues, or an unnatural amino acid has been incorporated for chemical modification. Such strategies include the incorporation of peptides, polymers, antibodies, stimuli-responsive moieties, and biorthogonal conjugation techniques that allow external control over Cas9 activation, localization, and activity. In addition, various short peptides have been either genetically fused or chemically conjugated for spatiotemporal regulation and probing. These approaches enable conditional activation of Cas9 in response to light, small molecules, or intracellular triggers, thereby minimizing off-target effects and increasing editing efficiency. In this review, we discuss a systematic evolution of chemically composed Cas9 (ChemComCas9) for precision genome engineering and gene therapy applications.</p>","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":" ","pages":""},"PeriodicalIF":4.3,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149177894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The N/O-containing groups in CAP partially reconstruct the Zn²⁺ solvation and water hydrogen-bond network, reducing water activity. Meanwhile, facet-selective adsorption of CAP on Zn(100), forms an adsorption-mediated interfacial layer that suppresses parasitic reactions and promotes compact Zn(100)-textured deposition. Consequently, Zn‖Zn symmetric cells operate stably for over 7000 h at 1 mA cm^-2/1 mAh cm^-2. Moreover, Zn‖ZVO full cells retain 82.45% capacity after 5500 cycles at 5 A g^-1.

This review first proposes an \"interface-energy-resource\" framework, systematically dissecting SIE applications in hydrogen production, lithium extraction, and power generation. Key challenges in each domain are analyzed, including carrier recombination and thermal management mismatch in hydrogen production, high Mg/Li ratio separation and membrane fouling in lithium extraction, and thermoelectric efficiency limitations and system losses in power generation. Moreover, this review highlights emerging materials (e.g., carbon, MXenes, ion-sieve membranes, Janus structures) tackling these challenges via cross-scale design.

However, the high chemical stability of CO₂ makes its efficient activation a central challenge. Molecular vibrational excitation can couple with reaction coordinates, thereby reducing the translational energy required to access transition-state regions and enhancing reactivity. Nonthermal plasma can generate vibrationally excited CO₂ under nonequilibrium conditions, offering a practical route to exploit vibrational activation in catalytic reactions. This Feature Article reviews how vibrational energy promotes CO₂ activation and examines the generation and relaxation of vibrationally excited CO₂ in plasma, together with its relevance to catalytic surface reactions. Particular emphasis has been placed on our mechanistic studies of plasma-catalytic CO₂ conversion, in which vibrationally excited CO₂ is proposed to couple with surface reaction coordinates and facilitate elementary steps that are difficult to achieve thermally.
