Using the first-principles calculations, we have designed a series of single transition metal (TM = Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Nb, Mo, Ru, Rh, Pd and Pt) anchored graphyne systems (TM-TEB). Notably, Ni-TEB and Pd-TEB emerge as promising candidates for OER/ORR bifunctional electrocatalysts, exhibiting lower overpotentials (<em>η</em>_OER, <em>η</em>_ORR) of (0.47, 0.44 V) and (0.36, 0.30 V), respectively, which rival ideal performance of IrO₂ for OER (0.56 V) and Pt for ORR (0.45 V). The superior catalytic activity is attributed to the favorable interactions between the active sites and the oxygen-containing intermediates, facilitating the adsorption and desorption during the catalytic process. The “acceptance-backdonation” mechanism effectively explains these interactions, originating from the moderate <em>p</em>-<em>d</em> orbital hybridization that governs electron transfer and redistribution between TM and adsorbed oxygen atom. This can be quantitatively elucidated through the surface-to-intrinsic descriptors analysis, including adsorption free energy (Δ<em>G</em>_ads), the number of <em>d</em> electrons (<em>θ</em>_e), ICOHP, charge transfer (ΔCharge), <em>φ</em> and <em>ε</em>. These intriguing results may inspire further exploration of bifunctional catalysts for energy storage and conversion applications.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"26 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143056545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There was significant orientation difference between adjacent lamellar α, and multiple slip may occur during the slip process. The microscopic fracture propagation pattern of basket-weave structure resembled a \"sawtooth\", signifying a high resistance to crack propagation and a robust capacity to inhibit propagation.

The role of local vacancy‐induced physicochemical properties on vanadium‐redox electrochemistry (VRE), encompassing kinetics, and stability, remains profoundly unveiled. Herein, for the first time, it is revealed that vacancies induce atomic‐scale polarization in TMOEs and elucidate its mechanism in VRE. Attributable to local polarization, particularly by cation vacancy, the activated nearest‐coordinated Mn sites prominently augment the adsorption competence of the V<jats:sup>2+</jats:sup>/V<jats:sup>3+</jats:sup> couple and expedite its round‐tripping by forming an intermediate *Mn–O–V bridge. It is also affirmed that the anion vacancies are vulnerable to microstructure reconfiguration by feeble hydroxyl adsorption and thus performance degradation over long‐term cycling, in contrast to cation vacancies. Accordingly, the VRFB employing cation‐vacancy‐functionalized electrode delivers an energy efficiency of 80.8% and a reliable 1000‐cycle lifespan with a negligible decay of 0.57% per cycle at 300 mA cm<jats:sup>−2</jats:sup>, outclassing others. The findings shed light on the fundamental rules governing the utility and evolution of vacancies in TMOEs, thereby moving a step closer toward their deployment in a wide range of sustainable energy storage schemes.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"16 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143056409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using glycerol as a cryoprotectant prevents ice crystal formation in gelatin‐derived hydrogel pores during storage at −20 °C. The hygroscopic properties provided by glycerol effectively preserve the structural and self‐healing features of the shell over time, supporting large‐scale production of off‐the‐shelf containers. As a proof‐of‐concept, the ability to manipulate the internal content, and real‐time analysis of internal pH, oxygen, and protein levels is shown. The nature of these capsules allows them to closely emulate the elasticity and self‐healing of natural cell membranes, enabling in situ modulation of the internal content without compromising the capsule structural integrity.

As a result, CrN/Cr/CrN and CrN coatings perform better corrosion resistance and durability than Cr/CrN/Cr coating. This is attributed to the superior chemical inertness and high compactness of CrN, which can block the penetration of the electrode effectively. All the coatings perform <em>p</em>-type semiconductors owing to the chromium oxides, and CrN/Cr/CrN coating shows the lowest acceptor density (<em>N_A</em>) owing to limited carrier transport caused by the interface effects between layers. Moreover, CrN/Cr/CrN coating has the lowest interfacial contact resistance (ICR) after PSP tests, which is attributed to the good corrosion resistance of the outer CrN layer and the inner Cr layer with high electron mobility.

However, these steels are susceptible to microstructural damage even at intermediate strain rates, which can compromise their performance in automotive application. This research aims to investigate the stress-strain response, internal temperature rise, and damage evolution in HSLA steels under quasi-static and intermediate strain rates. The initial microstructure of two different grades of HSLA steels, HR340 and HR550, are characterized using Electron Backscatter Diffraction (EBSD) data. During uniaxial tensile tests at various strain rates, a high-speed infrared thermal camera is utilized to capture the rise of the instantaneous surface temperature within the gauge section of the specimens. A new, thermodynamically consistent rate-dependent crystal plasticity formulation is developed. The damage evolution is governed by a thermodynamic driving force that accounts for various effects (i.e., temperature, void nucleation, and void growth). A power-law based damage formulation is proposed to account for the effects of strain rates and internal temperature rise on the damage evolution. The constitutive model is implemented into a crystal plasticity (CP) formulation to study the effects of damage, temperature and texture evolution on localized deformation in HSLA steel. The constitutive model is calibrated using experimental stress-strain data and temperature evolution measurements at different strain rates. The new model not only accurately predicts the softening/post-necking behaviour and failure of HR340 and HR550 but also accurately captures temperature variations in the material, aligning well with experimental results. The texture evolution prediction by the developed model also demonstrated good agreement with experimentally observed texture evolution at different strain rates. This study highlights the significant influence of strain rate and internal temperature rise on the damage, dislocation density evolution and microstructural behavior of HSLA steels. The model serves as a robust physics-based foundation for future investigative studies.","PeriodicalId":340,"journal":{"name":"International Journal of Plasticity","volume":"53 1","pages":""},"PeriodicalIF":9.8,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143056778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the intricate synergistic effect between H and He, the experimental results have not exhibited satisfactory consistency and, sometimes were contradictory. Via summarizing the previous results, it is suggested that the mechanism of the H-He synergistic effect is highly correlated with the H/He ratios. Based on this perspective, multi-beam ion irradiation experiments with four distinct H/He ratios were implemented on China Low Activation Martensitic (CLAM) steel, a candidate structural material for fusion reactors. The results showed that a low H/He ratio contributed to the dispersion of cluster nucleation, resulting in high-density small dislocation loops, whereas a high H/He ratio promoted the growth of defect clusters. Irradiation-induced hardening was observed to increase at low H concentrations and decrease at high H concentrations. The present study proposed that the H-He synergistic effect can be viewed from the perspective of the formation of H₂ molecules. The disparate responses of materials to the H-He synergistic effect may originate from the different H critical concentrations for the formation of H₂ molecules. This critical concentration should be determined by the factors such as material composition and irradiation conditions.","PeriodicalId":344,"journal":{"name":"Journal of Alloys and Compounds","volume":"130 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143057136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
