Abstract Wafers of Tb-doped GdAlO 3 / ? -Al 2 O eutectic were fabricated by the micro-pulling-down method using an Ir crucible with a 25 × mm die. A prototype X-ray phase imaging detector was developed CMOS sensor fiber optic plate and wafer. spots 8.24 ? m period observed detector. nylon ball diameter 4 also carried out. It that change approximately occurs at air–nylon interface. This techniqu...

The application of molecularly imprinted polymers (MIPs) as molecular scavengers for ambient plasma ionization mass spectrometry has been reported for the first time. MIPs were synthesized using methacrylic acid as functional monomer; nicotine, propyphenazone, or methylparaben as templates; ethylene glycol dimethacrylate as a cross-linker; and 2,2'-azobisisobutyronitrile as polymerization initi...

Abstract The controlled splashing of metal droplets plays a decisive role in the kinetics basic oxygen furnace (BOF) process. In this work, mathematical model was developed for predicting size distribution spherical ejected at an impingement zone. Harmonic oscillators are used to describe ejection sites, and upper limit droplet population is calculated through force balance. validated against l...

Using a graphite crucible as the counter-electrode, platinum microprobes with an aspect ratio of 30 and a tip apex radius less than 100 nm were fabricated by an electrochemical discharge etching process. The "neck-in" structure on the platinum wire induced by the electrical discharge at the liquid-air interface plays a key role in the probe shape and the voltage of the following pure electroche...

Thorough mixing of the starting materials is the first step of a crystal growth procedure. This holds true for almost any standard technique, whereas the intentional separation of educts is considered to be restricted to a very limited number of cases. Here we show that single crystals of α-Li2IrO3 can be grown from separated educts in an open crucible in air. Elemental lithium and iridium are ...

We report on the Czochralski method for single silicon crystal growth and discuss heat and mass transfer and defect formation in the crystal. A re ector was used for separation of the heating and cooling areas in the furnace enabling us to speed up crystal growth. The melt ow to stabilize the temperature distribution in a crucible was controlled using transverse magnetic elds in a large-scale s...

Sampling, sample recovery, laboratory preparation and analysis and performing calculations all introduce errors into a final test result. Even without any mistakes, random errors will remain. The precision of a method -the size of likely random errors from all sources from sampling tech­ niques through data reduction -is determined by analyzing the differences between simultaneous measurements....
