Single-wall carbon nanotubes (SWCNTs) are effectively narrow ribbons of two-dimensional (2D) materials with atomically precise edges. They ideal systems to harness quantum transport straintronics (QTS), i.e., using mechanical strain control transport. Their large sub-band energy spacing (approximately 0.8 eV) leads transistors a single channel. We adapt an applied model study QTS in uniaxially strained quasimetallic-SWCNT transistors. The realistic device parameters based on existing...
Microwave-absorbing materials with wide bandwidth and high absorptivity are increasingly playing an important role in over-the-air (OTA) testing. In this work, a kind of pyramid absorbing material was prepared using flame-retardant absorbers as the filler. addition, coating used to further improve properties microwave-absorbing material. To obtain excellent microwave absorption performance (MWAP), high-frequency structure simulator (HFSS) adopted design structural materials. Here, total...
Previously we have demonstrated surface plasmon enhanced energy transfer between fluorophores and gold nanorods under two-photon excitation using fluorescence lifetime imaging microscopy (FLIM) in both solution intracellular phases. These studies that nanoparticle-dye combinations are appealing, not only Förster resonance (FRET) imaging, but also transfer-based sensing of bio-analytes. Here, apply this approach to study the internalization (GNRs) HeLa cells early endosome labeling marker...
We report a fluorescent probe for mRNA detection. It consists of gold nanorod (GNR) functionalized with fluorophore-labeled hairpin oligonucleotides (hpDNA) that are complementary to the target gene. This nanoprobe was found be sensitive oligonucleotide, as indicated by significant changes in both fluorescence intensity and lifetime. The influence surface density hpDNA on performance this investigated, suggesting high hybridization efficiency could achieved at relatively low loading hpDNA....
The enhancement factor (EF) of surface-enhanced Raman scattering (SERS) from two-dimensional (2D) hexagonal silver nanorod (AgNR) arrays were investigated in terms electromagnetic (EM) mechanism by using the discrete dipole approximation (DDA) method. dependence EF on several parameters, i.e., structure, length, excitation wavelength, incident angle and polarization, gap size has been investigated. "Hotspots" found distributed gaps between adjacent nanorods. Simulations AgNR different...
Abstract With the spectacular physical properties of electrical conductivity, mechanical strength and thermal carbon nanotube (CNT) fibers are favored in many fields such as energy storage devices, sensing, electromagnetic shielding structural reinforcement, especially flexible sensing devices. However, lower tensile CNT limit their further application stretchable strain sensors, when monitoring large deformation variables. Here, large-scale continuous production has achieved through...
We demonstrate that time-resolved fluorescence spectroscopy is a powerful tool to investigate the conformation states of hairpin DNA on surface gold nanoparticles (AuNPs) and energy transfer processes in Au-nanobeacons. Long-range quenching Cy5 by AuNPs has been found be good agreement with electrodynamics modeling. Moreover, time-correlated single-photon counting (TCSPC) shown promising for real-time monitoring hybridization kinetics Au-nanobeacons, up 60% increase decay time component 300%...
Single-wall carbon nanotubes (SWCNTs) are effectively narrow ribbons of 2D materials with atomically precise edges. They ideal systems to harness quantum transport straintronics (QTS), i.e. using mechanical strain control transport. Their large subband energy spacing ($\sim$ 0.8 eV) leads transistors a single channel. We adapt an applied model study QTS in uniaxially-strained quasi-metallic-SWCNT transistors. The device parameters based on existing experimental platform, channel lengths $L=$...
