Abstract A scratch test is used to measure the adhesion between corrosion product film (CPF) and carbon steel in deionized water under different pH and temperatures. The fuzzy feature model is modified to minimize errors between calculation and scanning electron microscopy (SEM) results. Findings illustrate that the m…
A list of species of the water mitegenus Lebertia Neuman, 1880 known from Turkey is provided, based on bibliographical data and results from recent field work, mainly in the Southwestern part of the country. We describe one new species, Lebertia martinisp. n. and report new 28 locality records from 6 provinces for the…
Abstract We study the photoluminescence and photoluminescence excitation intensities of single‐walled carbon nanotubes. To derive the chirality fractions of semiconducting tubes from these optical methods requires a thorough analysis of the experimental parameters and the lifetimes of the excitonic states. We obtain t…
The paper describes an experimental study aimed at standardizing brazing procedure for joining Glidcop to OFE Cu for its application in upgraded photon absorbers of 2.5 GeV synchrotron radiation source, Indus-2. Two different brazing routes, involving brazing with silver base (BVAg-8) and gold base (50Au/50Cu) alloys,…

We present a method of selectively removing metallic single-walled carbon nanotubes (SWCNTs) from as-grown arrays on quartz substrates. The process utilizes an external silicon piece as a temporary global top gate to increase the resistance of the semiconducting SWCNTs while current is passed through the metallic SWCN…
In this investigation, tungsten oxide (WO 3 ) thin films have been deposited on unheated glass substrates by RF magnetron sputtering of tungsten target at constant oxygen partial pressure of 6 × 10 −2 Pa, sputtering power of 150 W and at different substrate bias voltages in the range from 0 to -150 V. The structural a…
We measured the intensity and angular distribution of the transmitted ions and neutrals in function of time (deposited charge) when 3 keV Ar7+ ions were inserted into capillaries of 200 nm diameter in a polymer foil. The fraction of neutrals was relatively large compared to other lower charge states. Interesting dynam…
This paper details the application of ANN in hardfacing technique to determine the optimal process parameters for submerged arc welding (SAW). The planned experiments are conducted on the semiautomatic submerged arc welding machine. The relationships between process parameters (arc current, arc voltage, welding speed,…
Self-assembled colloidal nanoparticle (NP) clusters are one of the bottom-up processing products to construct complex two- and three-dimensional optical materials. We show metal NP clusters chemically linked by a light-sensitive organic ligand to build up nanophotonic hybrid structures. NPs are spheres identical in si…
It is difficult to detect the signal of giant magneto-impedance (GMI) magnetic sensors with the signal-to-noise ratio (SNR) less than 0 dB by the conventional detection methods. In this paper, a novel detection circuit of a GMI sensor is presented, which directly samples the conditioned signals from the GMI sensor int…
The properties of asphalt modified by styrene–butadiene–styrene, polyvinyl acetate and waste crumb rubber separately in a wide range of polymer loadings were studied in this paper. In analysing the relationship between polymer loading and modified asphalt properties, we found that the ductility of polymer modified asp…
Abstract The transport properties of the junction assembled by zigzag graphene nanoribbons (ZGNRs) and Au electrode (Au/ZGNR) are investigated using first‐principles calculations. It is found that the Au/ZGNR junction behaves as a typical diode with Schottky barrier at the contact. Our results indicate that although t…
We report novel results on multiple photoionization of the N 2 molecule by femtosecond x-ray pulses from the Linac Coherent Light Source free electron laser. Ion spectroscopy reveals the ionization and dissociation dynamics, including a molecular mechanism of frustrated absorption that suppresses the formation of high…
This guide for a laboratory course presents an integrated set of experiments relying entirely on the use of unique enzyme, aspartate transcarbamylase, which exhibits all of the catalytic and regulatory properties characteristic of allosteric enzymes. A comprehensive study of this enzyme and its diss
Recently, model experiments using PMMA specimens and electric detonators were carried out to observe the propagation of cracks between two charge holes in blasting by Nakamura et al. [12]. The applicability of the guide hole method using a circular hole having two notches between the charge holes was examined. Control…
Abstract We report on the fabrication of a transparent photostable cell circuit composed of drive and resistor diodes which are face‐to‐face connected to each other with different device area. The diodes consisted of e‐beam evaporated p‐NiO on sputter‐deposited n‐ZnO for p/n diode formation on indium‐tin‐oxide glass.…
From heat capacity ( C p ) measurements on a single crystal sample of the spin ( S ) 1/2 two-leg spin-ladder material Cu(DEP)Br 2 above a critical magnetic field ( H c0 ) where the energy gap between the singlet ground state and the excited magnetic state closes, we have observed a peak anomaly, which is indicative of…
Zinc Aluminum Oxide(ZAO) thin films were deposited on glass substrates by DC reactive magnetron sputtering in an Ar+O 2 gas mixture using commercial available Zn metal (99.99% purity) and Al (99.99% purity) targets of 2 inch diameter and 4 mm thickness. The films were characterized and the effect of aluminum (Al) conc…
We present in this contribution results of two-step annealing, when the CdTe:Cl doped samples are at first annealed under Cd overpressure to remove inclusions and the re-annealed under Te overpressure to restore the high resistivity state. Investigation of samples after Cd rich annealing by infrared microscope has pro…
