Thermal Conductivity Characterization of Hafnium Diboride-Based Ultra-High-Temperature Ceramics
We evaluated the thermal conductivity of HfB2-based ultra-high-temperature ceramics from laser flash diffusivity measurements in the 25°–600°C temperature range.

Hafnium Reactivity with Boron and Carbon Sources Under Non-Self-Propagating High-Temperature Synthesis Conditions
Kinetic studies of the homogeneous and heterogeneous reactions, heat transfer model analyses, and their association with the investigation of microstructural phenomena were used to postulate the mechanism involved in the…

Near-Infrared Fluorescent Labeling of Tissue Transglutaminase Substrates for Imaging Tumor Boundaries
A novel strategy is developed to optically image tumor boundaries by cross-linking near-infrared fluorescent-labeled tissue transglutaminase substrates into tumor boundary tissue.

Plastic Flow Behavior of Inconel 718 Under Dynamic Shear Loads
The plastic deformation behavior of nickel–iron alloy Inconel 718 in shear was measured at strain rates of 0.01 s−1 and up to 3000 s−1 .

Thick Protective UHTC Coatings for SiC-Based Structures: Process Establishment
A new process to form thick and dense ultra-high-temperature ceramic (UHTC) composite coatings over SiC surfaces is described. Coatings of ZrB2/SiC/(ZrC) thicker than 100 μm are formed by a reaction-bonded…

High-Index-Contrast AlGaAs Waveguide Scattering Loss Reduction Via Oxidation Smoothing of Sidewall Roughness
The propagation loss of single mode high index contrast AlGaAs ridge waveguides is reduced nearly three orders of magnitude through application of a nonselective wet oxidation sidewall roughness smoothing technique.

Microscopic Theory of Electron Spin Relaxation in N@ C60
Here, we present a microscopic theory of electron spin relaxation in N@C60. The theory combines (1) the spin-orbit interaction of N 2p electrons, which mixes the ground-state 4S with excited 2P and 2D states.

Laboratory Determination of the Rate Coefficient for Three-Body Recombination of Oxygen Atoms in Nitrogen
A laser-based measurement of the rate coefficient for O-atom three-body recombination at room temperature is reported. The experiment employs the pulsed output of a fluorine laser at 157.6 nm to…

Electric Power from Artificial Muscles
In this work, as a novel process for use of renewable energy, the authors would like to discuss the possibility of an artificial muscle actuator based on a dielectric electroactive…
