comparison of the effects of two substrates and additives on pulse current electrodeposition of au nanoparticles showed that using indium-tin oxide instead of cu and cysteine instead of potassium iodide can improve morphology, current efficiency, photocatalytic effect and increase the number of nanocrystals. the examinations using the field-emission scanning-electron-microscope (fe-sem) showed ...

We have developed highly efficient white top-emitting organic light-emitting devices (TOLEDs) with broad emission by modifying both anode and cathode. To alleviate the undesirable microcavity effect and obtain “broad” white emission, CFxcoated Ag anode with modified reflectivity and an index-matching layer (SnO2) capped on thin Ca/Ag cathode with a maximal transparency of 80% were employed. A t...

All-AlGaN based high electron mobility transistors (HEMTs) are promising for increasing the power density in both RF and devices, improving overall efficiency. Nitrogen (N) polar GaN/AlGaN HEMTs offer lower contact resistance compared to its metal-polar counterpart. In this work, we report metal organic chemical vapor deposition (MOCVD)-based growth of N-polar AlGaN channel HEMT structures with...

BACKGROUND Macrophages play a major role among the inflammatory cells that invade muscle tissue following an injury. Low-level laser therapy (LLLT) has long been used in clinical practice to accelerate the muscle repair process. However, little is known regarding its effect on macrophages. OBJECTIVE This study evaluated the effect of LLLT on the mitochondrial activity (MA) of macrophages. M...

in the present study, the treatment of tannery wastewater was performed by electrocoagulationmethod (ec) using aluminium and steel electrodes. response surface methodology (rsm) with three factors; current density (i), electrolysis time (t) and ph, with each factor at five levels, was used to optimize the factors for higher chemical oxygen demand (cod) and total suspended solids (tss) removal. ...

The present study explores the use of carbon dots coated with Iron (II, III) oxide (Fe3O4) for its application as an anode in microbial fuel cells (MFC). Fe3O4@PSA-C was synthesized using a hydrothermal-assisted probe sonication method. Nanoparticles were characterized XRD, SEM, FTIR, and RAMAN Spectroscopy. Different concentrations Fe3O4- (0.25, 0.5, 0.75, 1 mg/cm2) onto graphite sheets (Fe3O4...

The research aimed to apply the Taguchi method for techno-economical evaluation of Cr+6 removal using the electro-coagulation process with the aid of two different coagulants (FeCl3 and PAC). Taguchi orthogonal array L27 (313) was applied for analyzing the effect of four variables including initial pH, reaction time, current density and coagulant types in an attempt to improve the chromium remo...

Hybrid Si/III-V, Fabry-Perot evanescent lasers are demonstrated, utilizing InGaAsP as the III-V gain material for the first time to our knowledge. The lasing threshold current of 300-mum-long devices was as low as 24 mA, with a maximal single facet output power of 4.2 mW at 15 degrees C. Longer devices achieved a maximal single facet output power as high as 12.7 mW, a single facet slope efficie...
