Our results confirm that acoustic cavitation in organic solvents generates free radicals which enable or are involved in secondary reactions. During the ultrasonication process, the addition of small molecules induces the formation of different carbon nanostructures mainly depending on the chemical nature of the molecule, as observed by transmission electron microscopy (TEM). Raman spectroscopy analysis confirms that small molecules act as radical scavengers reducing the damage caused by cavitation to graphene sheets producing long nanoribbons, squared sheets, or carbon nanoscrolls. Importantly, this strategy allows the production of different carbon nanostructures in liquid-phase making them readily available for their chemical functionalization or for their incorporation into hybrids materials enabling the development of new advanced biological applications.","PeriodicalId":157396,"journal":{"name":"Open Material Sciences","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121988831","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}

SC store energy based on two mechanisms: double layer capacitance (non-Faradaic) and pseudocapacitance (faradaic). Porous carbon materials have been extensively used as electrodes in SC, where their great surface area and pore size distribution have been the main properties for capacitance improvement. Nevertheless, these properties have shown limitations since they cannot be highly increased without losing electric conductivity, which is detrimental for the power requirements of SC. An alternative approach to increase capacitance has been the surface modification of carbon materials by introducing faradaic contributions. In this mini review, the effect of surface area, porosity, surface modification by doping or functionalization, and introduction of electroactive oxides are discussed to show how these factors influences the intrinsic capacitance values of different carbon materials; and some examples from our work are provided. The manipulation of such properties, on carbon materials (porosity and /or surface chemistry) not only are useful for devices such as SC, but also are very useful for a wide variety of Bio-applications (Bio-sensors, labelling and drug delivery, impregnation with microorganisms for its use as biochar, or for bio-fuel cells, etc.)","PeriodicalId":157396,"journal":{"name":"Open Material Sciences","volume":"443 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131399410","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}

Exposure of tracheal rings to SWCNTs did not modify the smooth muscle tone per se; however,when the ringswere pre-treated with the contractile agent acetylcholine (ACh), all SWCNTs concentrations (0.1-10 μg/mL) induced a transient contractile effect similar to that induced by ACh alone. Interestingly, the NO production was not modified by SWCNTs regardless of the presence of ACh 10 μM. Thus, the data suggest that NO is not involved in the airway smooth muscle contraction induced by SWCNTs. Further investigations are required to understand the effects, mediator(s) and mechanisms of action induced by this type of porous nanomaterial, as well as their fine interactions with the respiratory system structures.","PeriodicalId":157396,"journal":{"name":"Open Material Sciences","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115790810","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 photothermal sensitizing with mesoporous PSi NPs was demonstrated to be efficient for the hyperthermia of cancer cells and tumors in small animal models. The sonosensitizing properties of bare PSi NPs and dextran-coated ones were revealed by both the physical studies and biomedical experiments, which indicated a good prospect for their applications in sonodynamic therapy of cancer.
