The OER activity of the optimal compositions Ru_0.38Ga_0.62Ox and Ru_0.71Cr_0.29O_x surpassed that of pristine RuO_x. However, a 50 h chronopotentiometric study revealed a decisive shift in the activity-stability relationship, with Ru_0.71Cr_0.29O_x maintaining a nearly constant operating potential, whereas Ru_0.38Ga_0.62O_x rapidly deactivated due to Ga³⁺ leaching. X-ray photoelectron spectroscopy and electron microscopy confirmed that Cr³⁺ acts as a valence-pinning agent, suppressing Ru oxidation, thereby reducing the density of oxygen vacancies and number of stable covalent Ru-O bonds.

The number of reports on synthesis of such nitrides grows permanently but their majority deals, in the last years, with synthesis at very high pressures where even characterisation of the products (structure, composition etc.) becomes vague. The number of binary nitrides and related ternary compounds or solid solutions, accessible as macroscopic samples using large volume HP-HT apparatuses, appears to have stabilised at a high but still monitorable level. Today, the Gretchen question is whether the outcome of the 25-years activity was rewarding, whether any of the nitrides recoverable at ambient conditions exhibits properties deserving transfer to the industry. An answer is not straight because the efforts needed to obtain reliable property data go beyond those invested during the synthesis and characterisation. Gathering of such data requires either laborious investment in samples quality or development/adaptation of non-traditional, for HP-HT research, <i>in-</i> and <i>ex-situ</i> techniques. Here, the exposé of the most notable novel nitrides and their HP-HT synthesis routes is followed by examples of several recent developments/adaptations of experimental approaches permitting access to mechanical and optoelectronic properties which were earlier difficult to measure due to imperfect polycrystalline, porous and eventually contaminated samples. The revealed promising properties allow us to hope that the efforts were not futile and, at least, a couple of the discovered HP-HT nitrides could find industrial applications.</p>","PeriodicalId":21588,"journal":{"name":"Science and Technology of Advanced Materials","volume":"27 1","pages":"2718044"},"PeriodicalIF":6.6,"publicationDate":"2026-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13715347/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149300326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although surface engineering approaches have been studied to induce cell adhesion, precise control over attachment and detachment, comparable to that of adherent cells, remains challenging. Here, we report a strategy to control cell adhesion and detachment using enzyme-responsive trans-activator of transcription peptide-poly(ethylene glycol)-lipid (Tat-PEG-lipid) conjugates and non-functional poly(ethylene glycol)-lipids (PEG-lipid). A collagenase-cleavable peptide sequence was inserted between the Tat peptide and the PEG chain, yielding Tat-Col-PEG-lipid constructs with PEG molecular weights of 20 and 40 kDa. These conjugates were incorporated into the cell membranes of CCRF-CEM cells, a human T-lymphoblastoid cell line, to induce adhesion via the Tat peptide. To regulate the interfacial structure, Tat-Col-PEG-lipid was co-assembled with a non-functional PEG(5k)-lipid, enabling precise control over the surface density to improve collagenase access. We demonstrated that the mixed PEG-lipid modification allows robust cell adhesion to substrates while enabling efficient detachment upon collagenase treatment. Notably, the use of Tat-Col-PEG-lipids with longer PEG chains (40 kDa) significantly improved the adhesion efficiency, enzymatic detachment, and cell viability compared to shorter PEG chains. Optimal mixing ratios of Tat-Col-PEG(40k)-lipids and PEG(5k)-lipids resulted in stable attachment and rapid collagenase-triggered release across different substrates, planar surfaces, and fibrous scaffolds. This hierarchical PEG-lipid modification approach provides a versatile and minimally invasive platform for the transient manipulation of suspended cells, with potential applications in gene delivery, cell processing, and regenerative medicine.</p>","PeriodicalId":21588,"journal":{"name":"Science and Technology of Advanced Materials","volume":"27 1","pages":"2713991"},"PeriodicalIF":6.6,"publicationDate":"2026-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13508557/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148831886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this challenge, we develop a hexagonal boron nitride (hBN)-supported chalcogen substitution process that yields crack-free Janus TMD monolayers with improved optical uniformity.

Transmission electron microscopy (TEM) combined with electron diffraction has been one of the most reliable methods for characterizing the chiral indices of CNTs.

In this work, a Python code is developed with assistance from an artificial intelligence model (Claude Code) for the auto-extraction of CNTs' chirality from TEM images. Precise and reliable measurement of the diameter was realized by using a new method to determine the average distance between the bright and dark fringes. Symmetry and geometry-based rules enabled measurements of layer lines in the Fourier transformation of TEM images with a sub-pixel resolution. As a result, an accuracy higher than 90% for CNTs with diameters ranging from 0.5 nm to 3.0 nm was achieved.
