However, the high pull-off strength corresponding to the adhesive force matters when detaching fragile substrates. In this study, we present a vacuum-powered soft actuator with the dry adhesive, embeds oblique air chambers. The soft actuator performs coupled contraction and twisting by applying negative pneumatic pressure inward and exhibits not only high pull-off strength but also easy detachment. This effective detachment can be achieved thanks to twisting motion of soft actuator. The detachment performances of the actuator models are assessed using a 6-DOF robot arm. Results show that the soft actuators exhibit remarkable pull-off strength decrement from ~ 20 N cm−2 to ~ 2 N cm−2 due to the twisting. Finally, to verify a feasible application of this study, we utilize the inherent compliance of the actuators and introduce a glass transfer system for which a glass substrate on a slope is gripped by the flexibility of the soft actuators and delivers to the destination without any fracture.","PeriodicalId":21588,"journal":{"name":"Science and Technology of Advanced Materials","volume":" 39","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135191551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analysis of the structural properties revealed high mechanical stability with the 3.6% and 7.4% N-doped SWSiCNT. The calculated band gap of the N-doped SWSiCNT with 3.6% demonstrated a value of 2.56 eV which is within the photocatalytic range of 2.3 eV – 2.8 eV. The hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) potentials of the 3.6% N-doped SWSiCNT also showed good agreement with previous theoretical data. The studied material showed the best photocatalytic performance in both parallel and perpendicular directions by absorbing photons in the visible region. Therefore, the observed structural, mechanical, electronic and optical behaviors demonstrated by the 3.6% N-doped SWSiCNT exposed it as a better photocatalyst for hydrogen production under visible light.","PeriodicalId":21588,"journal":{"name":"Science and Technology of Advanced Materials","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135585023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In vivo and in vitro hemostasis studies suggested that BGNs has superior hemostatic properties to GZ (gauze) and GS (commercial gelatin sponge) and validated in vitro thrombosis, platelet adhesion, cytocompatibility and blood compatibility. The particles activated both endogenous and exogenous physiological coagulation pathways and could activate platelets and release Ca2+ to participate in the clotting pathway. Besides, the BGNs have good biocompatibility in vivo.

Spongy gelatin disks were prepared using gelatin solution concentrations ranging from 1% to 7% (v/w) within cylindrical tubes through programmed freezing, lyophilization, cutting, and dehydrothermal crosslinking and implanted in critical-sized defects of rat calvaria for up to 8 weeks. Analyses of disk implantation into rat calvaria defects by microfocus X-ray computed tomography and histomorphometry indicated that the bone volume was significantly larger in the 5% and 7% gelatin sponge groups than in the 1% and 3% gelatin sponge groups and tended to increase progressively from 5% to 7%. The histomorphometric analysis also showed that the largest number of new vessels was formed in the defect treated with 5% gealtin sponge compared to other gelatin sponges. Immunohistochemistry of matrix metalloproteinase (MMP) indicated that the gelatin concentration in the disks affected the appearance of MMP-2 and MMP-9 positive cells around the skeleton of the gelatin sponges. The degradation products of gelatin by MMP-9 and prolyl endopeptidase enhanced the formation of a capillary-like structure in human umbilical vein endothelial cells in vitro. These results suggested that the higher-density gelatin sponges tended to supply their own molecules via biodegradation, resulting in enhanced orthotopic osteogenesis through the expected function of gelatin molecules in angiogenesis and bone formation.","PeriodicalId":21588,"journal":{"name":"Science and Technology of Advanced Materials","volume":"10 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135821135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent progress towards high temperature localised emission relies on the application of strain to induce highly confined excitonic states. Here we propose an alternative paradigm based on curvature, rather than in-plane stretching, achieved through free-standing wrinkles of monolayer tungsten diselenide (WSe2). We probe these nanostructures using tip-enhanced optical spectroscopy to reveal the spatial localisation of out-of-plane polarised emission from the WSe2 wrinkles. Based on the photoluminescence and Raman scattering signatures resolved with nanoscale spatial resolution, we propose the existence of a manifold of spin-forbidden excitonic states that are activated by the local curvature of the WSe2. We are able to access these dark states through the out-of-plane polarised surface plasmon polariton resulting in enhanced strongly localised emission at room temperature, which is of potential interest for quantum technologies and photonic devices.","PeriodicalId":21588,"journal":{"name":"Science and Technology of Advanced Materials","volume":"14 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135820415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, based on previously reported OER catalyst materials of boron monosulfide mixed with graphene (r-BS+G), nickel foam (NF) is introduced as a supporting material for an r-BS+G electrocatalyst. The resulting r-BS+G-NF exhibits a very low overpotential at 10 (245 mV), 100 (308 mV), and 500 (405 mV) mA cm–2, with a low Tafel slope (56 mV dec–1). In addition, r-BS+G-NF exhibits high durability and can maintain high activity for more than 100 h at 100 mA cm–2. This is in sharp contrast to the catalyst without graphene (r-BS+NF), which shows lower durability. The results suggest that the unique morphology of the NF provides a large electrochemically active area and exposes more active sites on the surface of the prepared electrocatalyst, while the flexible graphene sheets play an important role as a support for effectively combining r-BS and NF. Consequently, the self-supporting structure can improve the OER performance as well as stability. Therefore, this study provides a promising strategy for use as an efficient and stable OER catalyst at high current densities.","PeriodicalId":21588,"journal":{"name":"Science and Technology of Advanced Materials","volume":" 17","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135813589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
