We study the electrochemistry of single layer graphene edges using a nanopore-based structure consisting stacked and Al(2)O(3) dielectric layers. Nanopores, with diameters ranging from 5 to 20 nm, are formed by an electron beam sculpting process on This leads unique edge which, along atomically thin nature embedded electrode, demonstrates electrochemical current densities as high 1.2 × 10(4) A/cm(2). The offers capability exchange at individual edge, isolated basal plane activity. also...
Interfacial water molecules are the most important participants in hydrogen evolution reaction (HER). Hence, understanding behavior and role that interfacial plays will ultimately reveal HER mechanism. Unfortunately, investigating is extremely challenging owing to interference caused by bulk complexity of environment. Here, behaviors different cationic electrolytes on Pd surfaces were investigated electrochemistry, situ core-shell nanostructure enhanced Raman spectroscopy theoretical...
Rapid and automated detection of acute myocardial infarction (AMI) at its developing stage is very important due to high mortality rate. To quantitatively diagnose AMI, Myo, CK-MB, cTnI are chosen as three biomarkers, which usually detected through an immunosorbent assay, such the enzyme-linked assay. However, approach poses many drawbacks, long time, cumbersome process, need for professionals, difficulty realizing automatic operation. Here, a multichannel digital microfluidic (DMF) thermal...
Abstract Magnetic resonance (MR) technology has been widely employed in scientific research, clinical diagnosis and geological survey. However, the fabrication of MR radio frequency probeheads still face difficulties integration, customization miniaturization. Here, we utilized 3D printing liquid metal filling techniques to fabricate integrative for experiments. The 3D-printed probehead with micrometer precision generally consists coils, customized sample chambers circuit interfaces. We...
We report ZnO inverse opal- and nanowire (NW)-based enzymatic glucose biosensors with extended linear detection ranges. The opal sensors have 0.01–18 mM range, which is 2.5 times greater than that of NW 1.5 other reported sensors. This larger range because reduced diffusivity through the geometry. an average sensitivity 22.5 μA/(mM cm2), diminished by 10% after 35 days, are more stable whose decreased 7 days.
Large-scale graphene oxide (GO) with adjustable resistivity was synthesized from graphite via an electrochemical method using KCl solution as effective electrolyte. During the exfoliation process, electrostatic force intercalates chloride ions between expanded layers on anode. These form small gas bubbles in reaction. It is believed that expand gap sheets and produce a separating adjacent layers. This overcomes Van der Waals exfoliates starting graphite. Because electrochemically oxidized by...
An atmospheric window is greatly significant in the radiative cooling field. In this study, we preliminarily design a thermally tunable metamaterial emitter that can be used as an internal and external emission switch for mid-infrared (3.5–5 8–14 μm). The proposed has multilayer metal–dielectric–metal micropyramid structure with thermochromic VO2 spacers. Its broadband thermal tunability are due to resonance of hybridization separate magnetic polaritons, surface plasmon phase-transition...

However, two major limitations spectral congestion high radio frequency power deposition are generally encountered conventional Carr-Purcell-Meiboom-Gill-based...
Abstract The photoanode plays a critical role in influencing the performance of dye‐sensitized solar cells (DSSCs). In this work, Y 0.80 Yb 0.18 Er 0.02 OF nanorods (YYEOF NRs) are synthetized by simple hydrothermal method and incorporated into TiO 2 film to form bi‐layer consisting nanoparticles (NPs) on bottom top. Owing improved light collection efficiency electron transport rate, resultant YYEOF NRs advantageous as dopants for DSSCs. Following assembly an integrated DSSC, enhanced...
A novel non-lithographic, contamination-free technique for the fabrication of graphene field effect transistors (GFET) is presented. The GFET was modified with C reactive protein aptamer. Iron nanoparticles were immobilized on channel surface by using an aptamer-target (CRP)-aptamer sandwich method. Bistability signal obtained backgate voltage up/down sweeping. bistability phenomenon caused target induced NPs adsorption demonstrates a high sensitive biosensing
