Electrospun and solution blown three-dimensional carbon fiber nonwovens for application as electrodes in microbial fuel cells
关键字：Electrospinning, microbial fuel cells, Carbon fiber
Three-dimensional carbon fiber electrodes prepared by electrospinning and solution blowing are shown to be excellent electrode materials for bioelectrochemical systems such as microbial fuel cells or microbial electrolysis cells. The bioelectrocatalytic anode current density is shown to reach values of up to 30 A m2, which represents the highest reported values for electroactive microbial biofilm...

04 Effect of Cl/Ni molar ratio on the catalytic conversion of polypropylene into Cu-Ni/C composites and their application in catalyzing "Click" reaction
关键字：Carbon materials, Catalysis, Composites, Polypropylene
A one-pot approach to prepare Cu–Ni/C heterogeneous composites by carbonization of polypropylene (PP) using combined catalysts of Ni2O3 and CuCl was proposed. TEM, SEM, TGA and Raman measurements were performed to investigate the effects of Cl/Ni molar ratios on the yield and morphology of the resultant carbon materials. The yield of carbon materials in Cu–Ni/C first increased and then decreased...

Supercritical Carbon-Dioxide-Assisted Deposition of Pt Nanoparticles on Graphene Sheets and Their Application as an Electrocatalyst for Direct Methanol Fuel Cells
关键字：graphene ， supercritical carbon dioxide ，Electrocatalyst
A combination of graphene with metal particles is particularly attractive due to the enhanced performance of the hybrid materials. However, direct loading of uniform metal
nanoparticles such as Pt on graphene remains a challenge due to the hydrophobic nature of graphene. We herein demonstrate that Pt nanoparticles with uniform size and high dispersion were deposited on graphene surfaces via a faci...

“Reactive” probe for hydrogen sulfite: Good ratiometric response and bioimaging application
关键字：Ratiometric probe, Hydrogen sulfite, Intramolecular charge transfer, Selectivity, Bioimaging application
4-(1H-Phenanthro[9,10-d]imidazol-2-yl)benzaldehyde (P-1) was prepared as a new ratiometric optical probe for hydrogen sulfite. Upon the addition of HSO3?, it displayed large emission wavelength shift ( 120 nm) and the detection limit was determined to be as low as 2 M. In addition to its high selectivity for hydrogen sulfite rather than other common anions, P-1 was successfully applied t...

Application of corncob-based activated carbon as electrode material for electric double-layer capacitors
关键字：corncob-based activated carbon; electrode material; electric double-layer capacitor
To investigate the influence of expansion pretreatment for materials on carbon structure, activated carbons(ACs) were prepared from corncob with/without expansion pretreatment by KOH activation, the structure properties of which were determined based on N2 adsorption isotherm at 77 K. The results show that the expansion pretreatment for corncobs is beneficial to the preparation ...

Application of Micro or Nano-sized Natural Polymeric Adsorbents in Heavy Metal Treatments
关键字：Chitin or chitosan nanofibrils，protein microspheres，heavy metals，biosorption，sorption behavior
Toxic heavy metal species are mobilized from industrial activities and fossil fuel consumption
and eventually are bioaccumulated through the food chain, leading to both ecological and health
problems. Recently, micro or nanoscopic materials including microspheres, nanobeads,
nanocomposites, magnetic nano adsorbents, and nanofibrous matrices, are of great interests to be
developed as efficient ...

Synthesis and characterization of a pentaerythritol-based amphiphilic starblock copolymer and its application in controlled drug release
关键字：star-like amphiphilic copolymer,RAFT polymerization,controlled drug release
A star-like amphiphilic copolymer was synthesized via RAFT polymerization by using a pentaerythritolbased
compound (PTDBA) as a chain transfer agent with Styrene and DMAEMA as monomers. The polymer
structure was characterized by FTIR, 1H NMR, 13C NMR and SEC/MALLS. After the retardation period,
the molecular weight of PS-CTA and PMMA-CTA increased linearly with monomer conversion. The
amphiphi...
