Furthermore, we have studied the effect of the number of carboxylic groups on photovoltaic properties. The absorption spectra of the novel sensitizers extended up to the red region (900 nm). The electrochemical studies reveal that the oxidation potentials are aligned below the iodine-based redox potential, feasible for easy regeneration and the LUMO of all sensitizers lie above the TiO2 conduction band, which is a favour for easy electron injection. The overall efficiency (η) of the GS16, GS17, and GS19 is 1.13%, 2.71%, and 1.59% with short circuit current (JSC) of 3.74 mA cm−2, 7.08 mA cm−2, 6.27 mA cm−2, open-circuit voltage (VOC) of 0.42 V, 0.54 V and 0.39 V and fill factor (FF) of 0.70, 0.70 and 0.65 respectively. The highest efficiency of 2.71% was observed in GS17, bearing the two anchoring groups compared to one and three carboxylic acid-containing sensitizers (GS16 and GS19).

In this study, we aim to capture the chemical changes of Pt surfaces brought on by an applied potential, which can probe the catalytic efficacy under varying applied bias. Through a combined experimental and reactive molecular dynamics (MD) simulation approach, we uncover the effect of charge build up on the surface of the Pt electrode, which can be directed towards capacitive and faradaic processes. In the case of a moderately acidic pH shown here, the potential dependence of simulated electrodic processes align well with the experimental results from electrochemistry and in situ surface enhanced Raman spectroscopy (SERS). Using reactive MD and SERS based studies, we are able to probe into the interfacial water structure and the formation of the Helmholtz layer. At reductive potentials of ∼0.3-0.0 V vs RHE, we simulate phenomenon such as under potential hydrogen adsorption and hydrogen evolution/oxidation reaction. Together, the investigation establishes a framework for quantitative exploration of catalytic processes in electrolytes at very high spatial and temporal resolution.","PeriodicalId":74385,"journal":{"name":"Oxford open materials science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41934676","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}

Graphene-based materials have acquired a huge share of interest in the scope of biosensor fabrication for early and accurate cancer diagnosis. Herein, we have insights reviewed the various routes and technologies for synthesized graphene, and graphene-based materials including 3D graphene (i.e., hydrogels, foams, sponges, porous), and 0D graphene (i.e., quantum dots). Moreover, we have introduced the different types of graphene/graphene-based materials biosensors (i.e., electrochemical biosensors, optical biosensors, field-effect transistors biosensors, electrochemiluminescence biosensors, and microfluidics biosensors) and their merits and applications for cancer pre-stage detection.","PeriodicalId":74385,"journal":{"name":"Oxford open materials science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49405945","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}

Developing novel solid-state electrolytes with high ionic conductivity and good interfacial contact is an urgent need. Here, to this end, a solid-state hybrid electrolyte is developed by mixing high-entropy lithium-containing metal oxide (Lix(Mg0.2Co0.2Ni0.2Cu0.2Zn0.2)1-xO, HEOLi) matrix and poly(ethylene oxide)-lithium salt binder and casting on PTFE substrate. By virtue of the low lithium-ion migration energy barrier of the HEOLi (0.36 eV) and the strong interaction between the oxygen vacancies of the HEOLi and the lithium salt anions, a biphasic transport of lithium ions in both inorganic and polymeric phases of the hybrid electrolyte is achieved, yielding a high ionic conductivity of 3 × 10−4 S cm−1 at 30 °C. The Li/Li symmetric cells with the hybrid electrolyte show a low overpotential of 45 mV and a long cycle life of more than 2500 h. Furthermore, coupled with the LiFePO4 cathodes and metallic lithium anodes, solid-state full cells with the hybrid electrolyte deliver a high capacity of 150 mAh g−1, stable cycle performance, and high safety. Consequently, hybrid electrolytes based on high-entropy metal oxides have broad application prospects in solid-state electrochemical energy storage and are expected to achieve lithium-metal batteries with high safety, high energy density, and long life.","PeriodicalId":74385,"journal":{"name":"Oxford open materials science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46587293","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}

Bones and teeth are vital organs that are susceptible to various disorders due to environmental, traumatic, genetic factors, and inherent malignant disorders. Most of the implants/prostheses normally used are cast and have a standard size and shape. Additive manufacturing has opened opportunities to replace these hard tissues with customized implants, prostheses, or the whole additive manufactured organ itself while considering anatomical/structural parts and functional aspects of the body. It helps to visualize and mimic internal organs/models, pre-planning via simulation, anatomical demonstration, treatments, and surgical teaching/training to technical staff by medical professionals. The current review covers additive manufacturing applications for the possible treatment of osteosarcoma, bone tumors, traumatic fracture, congenital anomalies, dental diseases, vertebral and cranial abnormalities, etc. from toe to head highlighting printing of long bones, short bones, cartilages, teeth, and more based on the general classification of bones shape i.e. the external shape and size of different bones with some case studies. The article has also touched upon the additive manufacturing competitive edge over the conventional methods in terms of complexity, easiness, cost-effectiveness, reduced time. However, the internal structures have not been addressed so far in additive manufacturing which could be a new corner to enhance the properties of bones and teeth in the future.","PeriodicalId":74385,"journal":{"name":"Oxford open materials science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46674419","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}
