A catalyst containing, on average, two Cu atoms per cluster (Ag11.192Cu2.808) delivers a CH4 faradaic efficiency of 17.1% at -1.6 V vs. RHE-dramatically higher than both the over-doped analogue Ag10.463Cu3.537 (11.16%) and the undoped Ag14 parent (∼0%). Density-functional-theory calculations reveal that introducing one to two Cu atoms optimally raises the Cu valence state, strengthening *CO adsorption and thereby accelerating the *CO → *CHO step that governs CH4 formation. These results demonstrate that 'less is more': beyond a critical Cu loading, the cooperative electronic advantages are diminished and activity declines.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"14 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144311659","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}

Beyond providing comparable electronic and redox properties to their fluoroarene analogues, the use of N-heterocycles allows for facile protonation of aromatic nitrogen atoms, thus providing a framework for tuneable reagents with varying Lewis basicity. The synthesized protonated borates were further examined as Brønstead-Lowry acids through pKa bracketing and evaluation of the kinetic accessibility of their protons by variable temperature NMR. Finally, we report the synthesis of onium and alkali metal salts of these borates through deprotonation by a variety of bases providing useful starting points for future applications.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"626 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144311660","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}

We developed peptide agonists utilizing β-sheet structures from FasL and TRAIL as scaffolds to induce oligomerization of CD95 and death receptor 5 (DR5) receptors. Computational design coupled with AlphaFold3 analysis identified four lead peptides: W10 and AP (targeting CD95) and EIA and EPR (targeting DR5). Bio-layer interferometry demonstrated nanomolar to micromolar binding affinities, while circular dichroism revealed conformational transitions upon target engagement. Target specificity was confirmed through colocalization and oligomerization studies, validating nanocluster formation. These peptides exhibited micromolar IC50 values against colorectal and breast cancer cell lines. Mechanistic investigations revealed enhanced nuclear translocation of NF-κB associated with apoptotic pathways. This ligand-derived scaffold approach introduces a novel strategy for developing TNFR peptide agonists with significant therapeutic potential against treatment-resistant malignancies.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"12 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144304836","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}

As a promising alternative, dual-ion batteries (DIBs), also known as anion-shuttle batteries, have gained attention for their high operational voltage and ultrafast charging capabilities. Unlike conventional rocking-chair batteries, DIBs utilize both cations and anions as charge carriers, reducing rate-limiting steps and eliminating long-range ion migration. This review provides a comprehensive analysis of the critical factors influencing DIB performance, with a particular focus on anion solvation structures, diffusion kinetics, electrolyte stability, and interfacial charge transfer mechanisms. We also explore how interface engineering enhances charge transfer efficiency and extends battery lifespan. In particular, we examine the role of the cathode electrolyte interphase (CEI) and solvation dynamics in stabilizing the electrode-electrolyte interface. By providing a comprehensive understanding of chemistry and dynamics in DIBs, this review sheds light on the future research directions for advancing sustainable DIBs technology.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"103 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144304832","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}

Here, we present a general strategy to systematically optimize interfacial electrocatalysts by engineering monomer composition and sequence of hetero-oligomer monolayers. These monolayers are prepared by electrochemically sequencing the addition of well-known catalytic complexes Ru(II)-qpyL1L2 (qpy = quaterpyridine, L1 = 9-(4-(pyridin-4-yl) phenyl)-9H-carbazole, L2 = 4-vinylpyridine) and Ru(II)-bdaL1L2 (bda = 2,2'-bipyridine-6,6'-dicarboxylate) onto self-assembled monolayers. The quantitatively engineering conductance, catalytic current densities, and overpotentials are studied as a function of molecular length, composition, and sequence. The catalytic current densities of homo-oligomer monolayers are enhanced by at least 20% as a function of the molecular lengths. The catalytic current density of the alternating hetero-heptamer monolayer is 10 and 2.4 times higher than those of the self-assembled and homo-heptamer monolayers, respectively. Our work opens up a simple and efficient pathway to optimize and enhance the catalytic performance of well-known interfacial molecular materials.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"5 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144304835","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}
