For over 40 years United Western Enterprises has been a national leader in the industry of photochemical etching with great appreciation for their consistent customer base. By integrating advanced technological equipment and updating a valuable re-certification status, this California based company made 2012 a year dedicated to customer needs. Camarillo, CA (PRWEB) December 18, 2012 If implementing new innovative machinery and being recertified to a vital ISO standard are on the annual...

Semiconductor Etching With Light
2012-09-29 05:28:50

redOrbit Staff & Wire Reports - Your Universe Online Researchers at one US university have developed a new, low-cost method of etching minute features onto semiconductor wafers while monitoring the process as it happens. University of Illinois electrical and computer engineering professor Gabriel Popescu and colleagues say that their method allows chipmakers to use a special microscope that uses two beams of light to precisely measure the topography. Their technique allows...

Gallium nitride (GaN) is a highly promising material for a wide range of optical and high-power electronic devices, which can be fabricated by dry etching with plasmas. However, the plasma-induced defects and surface residues that remain after such processes tend to degrade the optical and electrical properties of the devices. A team of Japanese researchers has developed and tested a new way to "heal" such defects. The team exposed plasma-damaged GaN to hydrogen (H) radicals at room...

Nano Art: Reloaded - Where Art And Science Collide
2012-04-03 04:38:20

Lee Rannals for RedOrbit.com [ Watch the Video ] Nanotechnology is a science that is being used by most of the Western culture on a daily basis, but the majority of people using do not even know it. People are unaware of the science that goes into making a device like a touchscreen smartphone that fits into a pocket, but Sameer Walavalkar is looking to change that. Nano Art: Reloaded is a project Walavalkar has created to combine both science and art, to bring nanoscale artwork to...

Butterfly Wings Inspire Water-repellent Surface Design
2011-11-22 04:14:46

The brilliant blue wings of the mountain swallowtail (Papilio ulysses) easily shed water because of the way ultra-tiny structures in the butterfly's wings trap air and create a cushion between water and wing. Human engineers would like to create similarly water repellent surfaces, but past attempts at artificial air traps tended to lose their contents over time due to external perturbations. Now an international team of researchers from Sweden, the United States, and Korea has taken...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
