The matter discovered at RHIC has shown a number of very surprising properties. It is extremely dense and has an initial energy density well above that expected for the phase transition from ordinary hadronic matter into quark gluon plasma. [1–4] The dense matter is very opaque to colored particles, such as quarks or gluons, traversing it. This gives rise to the striking jet quenching observed ...

A simple and rapid column-switching ion chromatography with non-suppressed conductivity detection method was developed for simultaneous determination of L-carnitine, choline and mineral ions (free sodium, potassium, magnesium and calcium ions) in milk and powdered infant formula samples. On-line sample clean-up was achieved on the pretreatment column Dionex IonPac NG1 (50 mm 4 mm, i.d.), with p...

This work reports on the development of a Johnson noise electro-thermal (JET) technique to directly characterize the thermal conductivity of one-dimensional micro-/nanoscale materials. In this technique, the to-bemeasured micro-/nanoscale sample is connected between two electrodes and is subjected to steady-state Joule heating. The average temperature rise of the sample is evaluated by simultan...

in this paper, the detector of moving target in mimo radar with widely separated antenna in the presence of α-stable clutter is proposed. due to the complexity of unknown parameter estimation in the presence of target, the rao test is applied. the α-stable model is a general model that can applied to different environments with appropriate selection of parameters. the problem with this model is...

The new possibilities of aberration-corrected scanning transmission electron microscopy (STEM) extend far beyond the factor of 2 or more in lateral resolution that was the original motivation. The smaller probe also gives enhanced single atom sensitivity, both for imaging and for spectroscopy, enabling light elements to be detected in a Z-contrast image and giving much improved phase contrast i...

A three-layer poly (methyl methacrylate) (PMMA) electrophoresis microchip integrated with Pt microelectrodes for contactless conductivity detection is presented. A 50 μm-thick PMMA film is used as the insulating layer and placed between the channel plate (containing the microchannel) and the electrode plate (containing the microelectrode). The three-layer structure facilitates the achievement o...

A new flow transducer for measuring the flow rate of a conducting fluid in a microchannel is reported. In this paper, the measure of flow of such fluid under laminar flow conditions based on the change of electrical admittance is established with the aid of a pair of electrodes parallel to the line of flow in a glass-PDMS microfluidic device. This flow sensor is simple in design and can be inte...

A simple, rapid, accurate, and practical headspace gas chromatographic method is proposed for the determination of hydrogen peroxide residues in bleaching effluent. This method is based on the reaction of hydrogen peroxide with ceric sulfate, under acidic conditions, where hydrogen peroxide is converted to oxygen, which is then measured using headspace gas chromatography (HS-GC) coupled with a ...

This study demonstrates superposing several eddy current distributions enables one to size defects much deeper than the depth of penetration from eddy current signals. A probe developed in an earlier study of the authors is utilized for the demonstration. The probe consists of four large exciters and one detector; the uniqueness of the probe is to realize an eddy current distribution that does ...
