The Sc leads the way as a potential candidate as compared to rechargeable batteries (Low power density, flexibility deficient, igneous as well as toxic nature) because of high power and tunable energy densities, affordability, outstanding cyclic performance, and adaptability. Metal organic frameworks (MOFs) and conducting polymers (CNDPs) are the most fascinating and extensively used electrode materials in flexible assemblies. The structural adaptability, sustainable surface area, three-dimensional porous architecture, and dominant permeability toward additives attribute the MOFs as innovative candidates for flexible electrodes. Likewise, CNDPs contains outstanding specific redox active capacity and inherent elastic polymeric nature, working as supreme pseudo capacitive constituents for the basis of flexible energy storage devices. Although, both materials have various advantages yet certain challenges like the low conductive nature of pristine MOFs and the substandard flexible performance of CNDPs still needs consideration. In addition, a better understanding must be developed to clarify the impacts of recent development and insights that might be used to direct future prospects. This review depicts the current progression toward the structuration of flexible supercapacitors based on MOFs, CNDPs, and their composites. The highlights of current advancement and residual challenges have been presented along with the comparison of hybridization strategies, and analysis of results obtained with directions toward future prospects of flexible supercapacitor.","PeriodicalId":94299,"journal":{"name":"Applied materials today","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135220644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The review was executed in a manner that laid a foundation for effective optimisation strategies to improve the print resolution or shape fidelity and cell viability of EBB through bioink. However, before achieving this aim the shearing characteristic of the bioink (i.e., shear-thinning or thickening) was described by the Ostwald-de Waele and Herschel-Bulkley models, among other reported models. The dependence of bioink shearing characteristics on temperature and time was also discussed. Emphasis on how these dependencies can be influenced by cross‐linking of bioink molecules was further highlighted, which can be covalent (chemical‐, photo‐cross-linking, etc.) or noncovalent (physical cross‐linking, host‐guest inclusion, ionic interaction, etc.). Models from literature that can physically describe print resolution and cell viability in EBB were discussed and compared. Therefore, multivariable‐multiobjective optimisation strategies were proposed with these models.","PeriodicalId":94299,"journal":{"name":"Applied materials today","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135219475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For instance, isoporous membranes with progressively smaller pore sizes can be stacked to create a hierarchical pore network in which each length scale and the gradient of the pore network are deterministic by design. In this paper, we introduce a hierarchically-arranged multilayer isoporous air filter that comprises an ultrathin (thickness <1μm) nanoporous active filtration layer and a microporous support layer. To maximize airflow and thereby reduce pressure drop across the membrane, we engineered a gap between the nanoporous and microporous membranes by designing and fabricating microscale spacer structures akin to feed spacers used in spiral wound reverse osmosis membranes. We demonstrated that such hierarchical isoporous membranes with integrated spacers (HIM-S) can retain high filtration efficiency (>95%) for ultrafine, most penetrating particle size (MPPS) while simultaneously reducing the pressure drop across the membrane (by ∼86%).","PeriodicalId":94299,"journal":{"name":"Applied materials today","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135618931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The electrochemical corrosion tests indicate that the scratched RHEA coating exhibits a higher electrochemical stability and a lower corrosion rate than the bare titanium alloy. The effects of the localized plastic deformation on the corrosion behavior for the RHEA coating was investigated. A slab model for the RHEA surface was proposed for the first-principles calculation to explored the change of the electron work function (EWF) as a function of external stress.

In this research, we effectively suppress strontium segregation by applying an anodic current that drives the segregated strontium back to the perovskite lattice and mitigate electrode performance degradation. By monitoring the impedance of Sr2Fe1.5Mo0.5O6-δ (SFM) air electrode under open circuit voltage at high temperature with changing current densities over time, the degradation caused by strontium segregation is verified. The applied current successfully prevent the polarization resistance from increasing is observed. The cell with 0.8 A/cm2 of the applied current increase only 3% of polarization resistance as compared to the cell without applied current after testing at 800 ℃ for 24 h. The atomic ratio of strontium on the SFM electrode surface shows lower strontium content after undergoing applied current, which means that the strontium is indeed migrated back to perovskite lattice under the applied current and result in slower degradation of the SFM electrode.","PeriodicalId":94299,"journal":{"name":"Applied materials today","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136382794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most hydrogels showed limited ability for self-biomineralization and can not guide the formation of new bone. Herein, according to the challenges encountered in advancing materials to clinical research, an injectable collagen-hyaluronic acid (Col-HA) hydrogel embedded with calcium sulfate nanorods (CSN) was developed via a bio-orthogonal reaction between norbornene (Nb) and tetrazine (Tz). The formulated [email protected] composite hydrogels not only have the potential to enhance cell adhesion and proliferation, but also serve as the system to control Ca2+ release. This composite hydrogel displayed impressive injectability, allowing straightforward in situ injection and subsequent adaption of composite hydrogels to irregularly shaped bone defects. CSN-incorporated composite hydrogels facilitate self-biomineralization, thereby fast-forming bone-like hydroxyapatite (HAp) within the hydrogel. Furthermore, Ca2+ released in a steady and sustained way from the composite hydrogels stimulated the differentiation of preosteoblasts, and promoted in situ bone growth. Our findings suggested that [email protected] composite hydrogels can successfully mediate the optimized CSN degradation, effectively accelerate HAp formation, and boost in situ bone development via the minimally invasive application.","PeriodicalId":94299,"journal":{"name":"Applied materials today","volume":"204 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136097246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
