At LBNL we are investigating the use of gaseous ion sources for induction linac applications such as heavy ion inertial fusion. Typical requirements for the ion source is to produce 20 μs pulses with a rise-time of 2 μs. The current density should be greater than 100 mA/cm2 at a duty cycle of 10 Hz [1]. Noble gases such as krypton, neon and xenon will be used. The source used for the measuremen...

The different weight ratios of Pd to Pt, i.e., 16:4, 10:10, 4:16 in Pd-Pt/C and (20 wt. %)/C electrocatalysts with low metal loading were synthesized for glycerol electrooxidation an air breathing microfluidic fuel cell (MFC). performance on Pd-Pt (16:4)/C anode electrocatalyst was found best among all the tested. single when tested at a temperature 35°C using (16:4)/C, showed maximum open cir...

the present study investigated oil/water demulsification and treatment of oily wastewater originated from port waste reception facilities by electro coagulation using aluminum electrodes in a batch reactor. the efficiency of al electrodes in removing ss, cod, and oil & grease from wastewater with different current densities and operational times were investigated. the characteristics of th...

This study presents biotreatment of textile wastewaters using electrocoagulation and ozone processes. Ozonation process gave better results than electrocoagulation process. For electrocoagulation, optimum working conditions were found as follows: pH, 6.5; electrode type, iron electrode; current density, 20 mA/cm2; and reaction time, 15 min. Under these circumstances, values determined for elect...

BACKGROUND Discharge of grey wastewater into the ecological system causes the negative impact effect on receiving water bodies. METHODS In this present study, electrocoagulation process (EC) was investigated to treat grey wastewater under different operating conditions such as initial pH (4-8), current density (10-30 mA/cm2), electrode distance (4-6 cm) and electrolysis time (5-25 min) by usi...

Graphene nanosheets have been synthesized from commercial expandable graphite by heating in a microwave oven and dispersing in ethanol by ultrasonication. Scanning and transmission electron microscopy and electron energy-loss spectroscopy and atomic force microscope showed that the nanosheets were about 2 nm in thickness and 10 microm in diameter. The field emission of the graphene sheets has b...

In this paper we present the effect of thickness variation of hole injection and hole blocking layers on the performance of fluorescent green organic light emitting diodes (OLEDs). A number of OLED devices have been fabricated with combinations of hole injecting and hole blocking layers of varying thicknesses. Even though hole blocking and hole injection layers have opposite functions, yet ther...

The application of synthetic colors in textile industries and their entry into the water and groundwater is an environmental problem because of being very toxic material. The synthetic colors which are used in textile dyeing (plyacrilic and polyester) are usually dispersing colorants. They derive the azo and anthraquinone chemicals. Electro-Fenton process is an efficient technique which can deg...
