“…These micrographs indicate 3D interconnected uniform mesostructures with obvious ultralarge-pore structure because of the introduction of swelling agent, which is consistent with the pore structure parameters from nitrogen adsorption-desorption isotherms ( Table 1). The structure of the honeycomb-like materials is in agreement with those of the MCFs materials previously reported [32,33]. These results indicate that the synthesized MCFs are promising materials for adsorption and separation applications in sample pretreatment.…”

h i g h l i g h t sTwo novel mesoporous cellular foams were synthesized and used as SPME coating. Four SPME fibers were prepared by sol-gel technology and immobilized resin method. New coating had excellent extraction ability to seven brominated flame retardants. g r a p h i c a l a b s t r a c t a r t i c l e i n f o a b s t r a c tTwo kinds of mesoporous cellular foams (MCFs), including mesoporous silica materials (MCF-1) and phenyl modified mesoporous materials (Ph-MCF-1), were synthesized and for the first time used as fibercoating materials for solid-phase microextraction (SPME). By using stainless steel wire as the supporting core, four types of fibers were prepared by sol-gel method and immobilized by epoxy-resin method. To evaluate the performance of the home-made fibers for SPME, seven brominated flame retardants (BFRs), including tetrabromobisphenol A (TBBPA), tetrabromobisphenol S (TBBPS) and related compounds were selected as analytes. The main parameters that affect the extraction and desorption efficiencies, such as extraction temperature, extraction time, desorption time, stirring rate and ionic strength of samples were investigated and optimized. The optimized SPME coupled with high performance liquid chromatography (HPLC) was successfully applied to the determination of the seven BFRs in water samples. The linearity range was from 5.0 to 1000 g L −1 for each compound except TBBPS (from 1.0 to 1000 g L −1 ), with the correlation coefficients (r 2 ) ranging from 0.9993 to 0.9999. The limits of detection of the method were 0.4-0.9 g L −1 . The relative standard deviations varied from 1.2 to 5.1% (n = 5). The repeatability of fiber-to-fiber and batch-to-batch was 2.5-6.5% and 3.2-6.7%. The recoveries of the BFRs from aqueous samples were in the range between 86.5 and 103.6%. Compared with three commercial fibers (100 m PDMS, 85 m PA and 65 m PDMS/DVB), the MCFs-coated fiber showed about 3.5-fold higher extraction efficiency.

“…Porous silica monoliths were produced through the calcination of porous hybrid polyHIPEs and nanocomposite polyHIPEs [34,39,50e54]. Solegel reactions in HIPEs containing an aqueous tetraethyl orthosilicate solution, but no organic monomers, were used to generate inorganic monoliths with highly interconnected porous structures termed Si-HIPEs [55]. Several approaches were used to generate macroporous carbons from macroporous polyHIPEs.…”

Here we report the first membrane-free biofuel cell obtained by using threedimensional carbonaceous foam electrodes. We first developed a new synthetic pathway to produce a new carbonaceous foam electrode material bearing porosity both in the meso and macroporous scale. We proved that by increasing the porosity of our three-dimensional foams we could increase the current density of our modified electrodes. Then, by choosing the right combination of enzyme and mediator, and the right loading of active components, we achieved high current densities for an anodic system. Finally, we combined the improved cathode and anode to build a new membrane-free hybrid enzymatic biofuel cell consisting of a mediated anode and a mediator-free cathode. This is a post-print version of the following article: Flexer, Victoria, Brun, Nicolas, Destribats, Mathieu, Backov, Rénal and Mano, Nicolas (2013) A novel three-dimensional macrocellular carbonaceous biofuel cell. Physical Chemistry Chemical Physics, 15 17: 6437-6445.
