Exploring low-cost and high-performance nonprecious metal catalysts (NPMCs) for oxygen reduction reaction (ORR) in fuel cells metal-air batteries is crucial the commercialization of these energy conversion storage devices. Here we report a novel NPMC consisting Fe3 C nanoparticles encapsulated mesoporous Fe-N-doped carbon nanofibers, which synthesized by cost-effective method using carbonaceous pyrrole, FeCl3 as precursors. The electrocatalyst exhibits outstanding ORR activity (onset...
Abstract Poor cycling stability and safety concerns regarding lithium (Li) metal anodes are two major issues preventing the commercialization of high‐energy density Li metal‐based batteries. Herein, a novel tri‐layer separator design that significantly enhances batteries is presented. A thin, thermally stable, flexible, hydrophilic cellulose nanofiber layer, produced using straightforward paper‐making process, directly laminated on each side plasma‐treated polyethylene (PE) separator. The...

Despite a large number of publications describing biosensors based on electrochemical impedance spectroscopy (EIS), little attention has been paid to the stability and reproducibility issues sensor interfaces. In this work, faradaic EIS analyses aptamer/mercaptohexanol (MCH) self-assembled monolayer (SAM)-functionalized gold surfaces in ferri- ferrocyanide solution were systematically evaluated prior after aptamer-probe DNA hybridization. It is shown that data exhibited significant drift,...
Abstract A homemade gold electrode is modified with a carbon nanotubes/gold nanoparticles nanocomposite to perform selective and sensitive electrochemical detection of dengue toxin. This nanostructured composite offers large specific surface reactive interface allowing the immobilization biological material. Dengue antibodies are immobilized on via covalent bonding for toxin detection. The porous tridimensional network nanotubes enhances signal overall performance sensor. After optimization,...
Matrix Metalloproteinase-7 (MMP-7) is a proteolytic enzyme overexpressed in different pathological conditions, including cancer, infection, and cardiovascular diseases, relevant diagnostic biomarker potential drug target. Here we demonstrate rapid selective detection of MMP-7 with limit-of-detection 6 pg/mL dynamic range from 1 × 10−2 to 103 ng/mL using peptide decorated gold nanoparticle/carbon nanotube electrochemical sensor. The sensor could be operated diluted human serum synthetic...
Recent developments in the fabrication of hollow spheres have allowed our group to prepare a new type macroporous ceramics: sphere ceramics ( HSC s). Alumina were first produced by centrifugal spray‐drying particle‐stabilized foam slurry. The obtained sintered together form at high temperatures. effect sintering temperature on linear shrinkage, porosity and compressive strength samples was investigated. When increased from 1400°C 1600°C, shrunk increasingly decreased 59% 42%, which lead an...
Biocatalysis is now a well-established branch of catalysis and the growing toolbox natural, evolved designer enzymes enabling chemistry previously deemed inaccessible. However, most enzyme methodologies have been developed for functional group interconversions, such as conversion ketone to an amine or alcohol, do not result in generation significant 3D molecular complexity. The application enzyme-triggered reaction cascade has potential transform simple substrates into complex sp3-rich...
Aluminum hydride (AlH3), with gravimetric hydrogen capacity exceeding 10 wt. %, has shown a great potential as an alternative energy storage material. Due to its high reactivity, the practical utilization of AlH3 relies on safe storage, handling, and transportation. During would be slowly released through reaction moisture oxygen under ambient conditions. When mixed other fuels during transportation, heat generated from interparticle friction may lead temperature rise, resulting in rapid...
Despite the increasing popularity of microfabricated biosensors due to advances in technologic and surface functionalization strategies, their successful implementation is partially inhibited by lack consistency analytical characteristics. One main causes for discrepancies absence a systematic comprehensive approach functionalization. In this article gold electrodes aimed at biosensor development have been systematically characterized terms pretreatment, thiolated molecule binding,...
Rapid and reliable antibiotic susceptibility testing (AST) platform is highly desired to select the right antibiotics treat infectious disease at early stage. Here, we demonstrate rapid ASTs using nanoscale silicon ion-selective field-effect transistor sensors. Our sensors profile bacterial metabolic kinetics by monitoring metabolism induced acidification in growth media with absence presence of different antibiotics. AST results could be determined from profiles a total assay time less than...

As the signals of potentiometric-based DNA ion-selective field effect transistor (ISFET) sensors differ largely from report to report, a systematic revisit this method is needed. Herein, hybridization target and probe on sensor surface its dependence coverage ionic strength were systematically investigated by plasmon resonance (SPR). The maximum potentiometric signal that could be registered an ISFET was estimated based SPR measurements, without considering buffering effects any side...
