GaSb-based interband cascade lasers (ICLs) emitting at a center wavelength of 6.12 µm 20 °C in continuous-wave operation up to maximum operating temperature 40 are presented. Pulsed measurements based on broad area devices show improved performance by applying the recently published approach adjusting Ga 1 − x $_{1-x}$ InxSb layer thickness active region reduce valence intersubband absorption. ...

Tarnish and Corrosion behavior of three Commercial dental amalgams namely Am.1, Am.2, Am.3, have been investigated by utilizing in vitro tests. The corrosion and/or dissolution rate of the three dental amalgams were studied in 0.9 wt% NaCl Solution, artificial saliva and Ringers solution. Potentiodynamic polarization technique was employed to study cathodic and anodic polarization behavior, fro...

the lethality of pulsed ultra-violet (uv) rich light for the inactivation of pathogenic bacteria has been investigated. a low pressure xenon filled flash lamps that produced uv intensities have been used. the pulsed operation of the system enable the release of electrical energy stored in the capacitor into the flash lamp within a short time and produces the high current and high peak power req...

in this study, an attempt was made to minimize the corrosion rate and maximize pitting potential of dissimilar metal welded joints of a387-gr91/aisi316 steels. process parameters of the pulsed current gas tungsten arc welding (pcgtaw) including of peak current (p), background current (b), pulse frequency (f), and on time percentage (o) were chosen as the influencing factors on corrosion behavio...

The study presents the corrosion behaviour and wear response of pulsed electric current sintered binderless TiC 50 N , 70 30 90 10 based ceramic composites, consolidated by spark plasma sintering (SPS), relative densities were evaluated using Archimedes principle. microstructural evolutions samples examined through various microscopy techniques, their susceptibility to in aggressive chloride en...

The scanning droplet cell (SDC) allows for automatized electrochemical experiments leading to time-saving and reproducible experimental conditions. Its implementation non-aqueous battery research is discussed, the necessary adaptations be operated inside an Ar-filled glovebox in complete absence of oxygen moisture are described. Due importance use Li metal electrodes next-generation high-energy...

Abstract YAG (Yttrium Aluminum Garnet) was successfully prepared through cathodic electrodeposition process using applying different current densities to the mixture of YCl3 and AlCl3 dissolved in water/ethanol 1:1 solution. Hydroxide precursors were cathodically grown on the cathode surface (at different current densities) and then the obtained hydroxide powder was heat-treated at 1100 °...
