Abstract Acoustic tweezers use ultrasound for contact-free manipulation of particles from millimeter to sub-micrometer scale. Particle trapping is usually associated with either radiation forces or acoustic streaming fields. based on single-beam focused vortices have attracted considerable attention due their selective capability, but proven difficult three-dimensional (3D) without a complex transducer array and significant constraints the trapped particle properties. Here we demonstrate 3D...
Photolithography is the technology of choice for mass patterning in semiconductor and data storage industries. Superlenses have demonstrated capability subdiffraction-limit imaging been envisioned as a promising potential nanophotolithography. Unfortunately, patterns generated by current superlenses exhibited poor profile depth far below requirement photolithography. Here, we report an experimental demonstration sub-50 nm resolution nanophotolithography via smooth silver superlens with high...
The O 2 -reaction chemistry of 1:1 mixtures (F 8 )Fe II (1; F = tetrakis(2,6-diflurorophenyl)porphyrinate) and [(L Me N )Cu I ] + (2; L , -bis{2-[2-( ′, ′-4-dimethylamino)pyridyl]ethyl}methylamine) is described, to model aspects the occurring in cytochrome c oxidase. Spectroscopic investigations, along with stopped-flow kinetics, reveal that low-temperature oxygenation 1/2 leads rapid formation a heme-superoxo species III -(O \documentclass[12pt]{minimal} \usepackage{amsmath}...
This paper investigates the mechanism of self-stabilizing, three-dimensional Mie particle manipulation in water via an acoustic tweezer with a single transducer. A carefully designed lens is attached to transducer form vortex, which provides angular momentum on trapped polymer sphere and leads fast-spinning motion. The can find equilibrium positions spontaneously during by slightly adjusting its relative position, velocity, spinning axis. motion greatly enhances low-pressure recirculation...
NO and CO may complement each other as signaling molecules in some physiological situations. We have examined the binding of to human heme oxygenase-1 (hHO-1), an enzyme that oxidizes biliverdin, CO, free iron, determine whether inhibition hHO-1 by can contribute interplay CO. An Fe<sup>3+</sup>-NO hHO-1-heme complex is formed with or donors NOC9 2-(<i>N,N</i>-diethylamino)-diazenolate-2-oxide·sodium salt. Resonance Raman spectroscopy shows ferric forms a 6-coordinated, low spin NO. The...
Mutation of His-39, one the axial ligands in rat outer mitochondrial membrane cytochrome b5 (OM cyt b5), to Val produces a mutant (H39V) capable carrying out oxidation heme biliverdin when incubated with hydrazine and O2. The reaction proceeds via formation an oxyferrous complex (FeII-O2) that is reduced by ferric hydroperoxide (FeIII-OOH) species. latter adds hydroxyl group porphyrin form meso-hydroxyheme. observation catalase does not inhibit H39V consistent coordinated (FeIII-OOH), which...
Amorphous boron nitride thin coatings (∼0.2 μm) have been formed on Nicalon and C‐Nicaion (pre‐carbon‐coated Nicalon) yarns via dip coating in boric acid solution followed by heating nitriding NH 3 gas at 1000°C. X‐ray photoelectron spectroscopy (XPS) Auger electron spec‐troscopy (AES) studies shown the formation of nitride. The was rich contains oxygen. N/B O/B ratios range from 0.6 to 0.8 0.1 0.25, respectively. Tensile strength measurements revealed that BN‐coated C‐Nicalon yarn...
The membrane-bound NO reductase from the hyperthermophilic denitrifying archaeon Pyrobaculum aerophilum was purified to homogeneity. enzyme displays MQH2:NO oxidoreductase (qNOR) activity, consists of a single subunit, and contains heme nonheme iron in 2:1 ratio. combined results EPR, resonance Raman, UV-visible spectroscopy show that one hemes is bis-His-coordinated low spin (gz = 3.015; gy 2.226; gx 1.45), whereas other adopts high configuration. also center, which oxidized...

The dielectric-barrier-discharge (DBD) plasma actuator is a popular technology for active flow control; however, the influence of heat generated by on its performance seldom mentioned. In this work, an experimental investigation conducted to evaluate interaction between spontaneous generation and alternating-current DBD (AC-DBD) actuator. characteristics AC-DBD are examined temporally in quiescent air, including profile induced flow, capacitance properties, power consumption, light emission,...
In cytochrome c oxidase synthetic modeling studies, we recently reported a new μ-η2:η2-peroxo binding mode in the heteronuclear heme/copper complex [(2L)FeIII−(O22-)−CuII]+ (6) which is effected by tridentate copper chelation (J.
