Specifically, electrical performance predictions for A-CNT CMOS FETs at various technology nodes are built based on a theoretical model and experimental results, and then, the criteria for ideal A-CNTs are outlined by evaluating the energy-delay product (EDP) advantage of CNT FETs over similar node commercial silicon (Si)-based CMOS transistors. The fine requirements for A-CNT materials are estimated for 90 nm, 22 nm, 7 nm, and 3 nm node CNT CMOS FETs, which present significant advantages in terms of energy efficiency over Si CMOS transistors. The criteria will guide the development of CNT materials for future ICs and provide a comprehensive assessment of the opportunities and challenges in CNT electronics.</p></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"79 ","pages":"Pages 97-111"},"PeriodicalIF":21.1,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142228914","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}

However, the development of direct methane SOFCs is primarily hindered by the poor coking tolerance of the state-of-the-art Ni-based cermet anodes. Herein, we efficiently construct nano-interfaces in the anode by infiltrating a Ni<sub>0.6</sub>Y<sub>0.064</sub>Zr<sub>0.336</sub>O<sub>2-δ</sub> (NYZ) catalyst onto the traditional Ni-based cermet anode to effectively enhance the coking tolerance.

The roughened anode demonstrates significantly improved fuel oxidation activity and coking tolerance, due likely to the formation of nano-interfaces. Specifically, when applied in the Ni-YSZ-based anode-supported SOFCs, a high peak power density of 1.785 W cm<sup>−2</sup> and a stable operation of ∼ 240 h with no observable degradation is achieved at 750 °C in nearly dry methane (3 % H<sub>2</sub>O). A density functional theory study suggests that the excellent coking tolerance is attributed to the formation of OH species on Ni/YSZ nano-interfaces, which would further interact with intermediate carbon species to generate COH intermediates.</p></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"79 ","pages":"Pages 28-35"},"PeriodicalIF":21.1,"publicationDate":"2024-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142228909","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}

In the case of acute and chronic liver injury, the disrupted liver microenvironment induced by activated hepatic stellate cells (aHSCs) would suppress immune surveillance and license the re-multiplication of disseminated tumor cells (DTCs). Herein, a cyclic peptide pPB modified nanovesicle with aHSCs targeting capability was constructed as CP-SB-siRNA to co-deliver hydrophobic SB431542 and nucleic acid drug CXCL12 siRNA. Due to the TGF-β signaling inhibition of SB431542, CP-SB-siRNA significantly suppressed the expression levels of genes coding the uppermost fibrosis-associated proteins including <em>α-sma</em>, <em>Col-1</em> and <em>Col-3</em> in aHSCs. On the other hand, the gene and protein expression level of metastasis-associated chemokine CXCL12 was significantly decreased. In addition, CP-SB-siRNA could regain the function of NK cells and attenuate the breast cancer proliferation through CXCL12-CXCR4 axis. On both breast cancer spontaneous metastasis with fibrosis mouse model and breast cancer via hematogenous metastasis with fibrosis mouse model, CP-SB-siRNA successfully reversed hepatic fibrosis by regressing aHSCs, and thereby restored the liver microenvironment, ultimately inhibiting breast cancer hepatic metastasis. This nanomaterial vector, featuring targeting and drug co-delivery functionalities, exhibited a great potential to restrain breast cancer hepatic metastasis based on the relationship among aHSCs, NK cells and DTCs.</p></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"79 ","pages":"Pages 1-15"},"PeriodicalIF":21.1,"publicationDate":"2024-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142228907","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}

For 4D printed smart materials, all the changes programmed in the materials follow a mathematical model that allows scientists to predict and design the desired behaviors of the structures, using parameters such as the material distribution and the spatial gradients of the metric tensor. We finally conclude with the discussion of future challenges and opportunities for this ever-growing technology.

Here, inspired by mushroom gills, we propose a mechanism for the snap-through buckling induced by geometric frustration, and we construct a snap-through metamaterial (STM) to address this problem. By analyzing the bifurcation buckling phenomenon, the STM is improved with higher energy-dissipation efficiency. Experiments demonstrate that the STM adaptively dissipates energy and mitigates impacts, achieving up to 33% reduction, in a reusable, self-recoverable, and rate-independent manner, leading to comprehensive performance. Employing a preloading strategy further enhances its impact mitigation capability as required. Notably, the STM exhibits a remarkable load-bearing capacity of up to 55 times higher than those of previous designs. The proposed design strategy of STMs paves the way for the development of interaction-based metamaterials, enabling applications in advanced dampers, mechanical waveguides, soft robotics, and low-frequency energy harvesters.</p></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"77 ","pages":"Pages 11-18"},"PeriodicalIF":21.1,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141943242","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}
