Cracks in Magnetic Nanocrystal Films: Do Directional and Isotropic Crack Patt...
In this letter, we show that the use of nanocrystals enables new insights into the scaling law of crack patterns. Directional and isotropic crack patterns made of γ-Fe2O3... -
Magnetic measurement of strain-induced martensite formation in Fe–30Ni steel
This investigation focuses on deformation-induced plasticity in Invar-type steel alloys. The effect is being studied in an austenitic model alloy, containing 30 wt-% of nickel.... -
Ligand-Induced Anisotropy of the Two-Photon Luminescence of Spherical Gold Pa...
Here we report on the visible luminescence properties of individual spherical gold particles in solution, obtained by two-photon excited fluorescence correlation spectroscopy... -
Self-supporting soft carbon fibers as binder-free and flexible anodes for hig...
Sodium batteries are considered as the most promising candidates for next generation power source. Carbon materials are the most viable anode material for sodium ion batteries.... -
A Multi-Wall Carbon Nanotube Tower Electrochemical Actuator
Patterned multiwall carbon nanotube arrays up to four millimeters long were synthesized using chemical vapor deposition. Electrochemical actuation of a nanotube array tower was... -
Hyperspectral photoacoustic spectroscopy of highly-absorbing samples for diag...
ABSTRACTPhotoacoustic spectroscopy has been used to measure optical absorption coefficient and the application of tens of wavelength bands in photoacoustic spectroscopy was... -
Flexible Piezotronic Strain Sensor
Strain sensors based on individual ZnO piezoelectric fine-wires (PFWs; nanowires, microwires) have been fabricated by a simple, reliable, and cost-effective technique. The... -
Ionic Screening of Charged-Impurity Scattering in Graphene
We have studied the ionic screening effect on the charge transport properties of graphene field effect transistors. By increasing the ionic concentration, we found dramatic... -
Contact Geometry and Conductance of Crossed Nanotube Junctions under Pressure
We explored the relative stability, structure, and conductance of crossed nanotube junctions with dispersion corrected density functional theory. We found that the most stable... -
Carbon Nanotubes as Injection Electrodes for Organic Thin Film Transistors
We have investigated the charge injection efficiency of carbon nanotube electrodes for organic semiconducting layers and compared their performance to that of traditional noble... -
Charge Transport in Dual Gated Bilayer Graphene with Corbino Geometry
The resistance of dual-gated bilayer graphene is measured as a function of temperature and gating electric fields in the Corbino geometry which precludes edge transport. The... -
Suppression of Auger Processes in Confined Structures
We explore how the size and shape of the microscopic confinement potential affects the nonradiative Auger decay rate of confined carriers. Calculations conducted in the... -
Chitosan-coated filter paper with superhydrophilicity for treatment of oily w...
ABSTRACTThe separation of oil and water mixtures is an important issue in acidic and alkaline conditions. In this paper, the chitosan (CS)-coated filter paper was successfully... -
Monolayer Suppression of Transport Imaged in Annealed PbSe Nanocrystal Arrays
We use correlated electrostatic force, transmission electron, and atomic force microscopy (EFM, TEM, and AFM) to visualize charge transport in monolayers and up to five layers... -
Two Distinct Buckling Modes in Carbon Nanotube Bending
By using controlled SPM manipulation, carbon nanotubes have been continuously bent into a series of increasing angles, and two distinct buckling modes corresponding to “abrupt”... -
Effect of Hydrocarbon Chain Length of Amphiphilic Ruthenium Dyes on Solid-Sta...
We studied the influence of the hydrophobic hydrocarbon chain length of amphiphilic ruthenium dyes on the device performance in solid-state dye-sensitized solar cells. We found...
