Typically, silver nanoparticles--particles that are 1 to 100
nanometers in diameter--are grown in a bulk chemical solution.
For comparison, a strand of human hair is about 50,000
nanometers thick.
Scientists can now view structures just 45 to 84
nanometers wide, Nobel Prize-winning physicist Eric Betzig of the Howard Hughes Medical Institute's Janelia Research Campus in Ashburn, Va., and colleagues report in the Aug.
Nanoscience is the study of structures and materials on the scale of
nanometers. To give you an idea of how long a
nanometer is, this printed page is about 75,000
nanometers thick.
Intel's latest chips have transistors with features as small as 14
nanometers, but it is unclear how the industry can keep scaling down further or what might replace silicon.
Scientists have known for decades that gases from pine trees can form particles that grow from just 1
nanometer in size to 100
nanometers in about a day.
said Tuesday it has developed what it claims to be the world's thinnest fiber, measuring 150
nanometers in diameter
PPG Industries has been granted a patent for a coating composition comprised of a continuous phase comprised of water and a dispersed phase comprised of a microgel having a mean particle size of greater than 50
nanometers to 900
nanometers and formed from reactants comprised of no more than 5% by weight, based on the total weight of the reactants, of a multi-ethylenically unsaturated compound, and a plurality of monoethylenically unsaturated compounds selected so as to provide a copolymer having a calculated Tg of greater than 100[degrees] C and comprised of a cycloaliphatic (meth)acrylate.
"The panorama combines exposures taken through Pancam filters centered on wavelengths of 753
nanometers (near infrared), 535
nanometers (green) and 432

Tokyo, Jan 23, 2012 - (JCN) - Teijin Fibers Limited, the core company of the Teijin Group's polyester fibers business, has decided to commercialize a new version of its Nanofront high-strength polyester nanofiber with a diameter of 400
nanometers, or 22,500 times smaller than the cross-sectional area of a strand of hair, an unprecedented achievement for a commercial polyester fiber.
Powerchip has been introducing 30-nanometer process with monthly output of 130,000 12-inch wafers, while Rexchip is being equipped with advanced process technologies at 40 and below
nanometers with output of 80,000 units a month.
The world s No.2 NAND flash memory maker behind Samsung Electronics Co has already ordered chip-making equipment from ASML to produce microchips with circuitry widths of less than 25
nanometers, the Nikkei said.
