Computer simulation and lab synthesis find best molecules

Chemistry professor Weitao Yang and two post doctoral associates proposed a computer-assisted way to find novel and superior materials. “linear combination of atomic potentials” (LCAP), is a property of all molecules. LCAP accounts for energy relationships between electrons and associated nuclei in the atoms making up all possible molecules. Using LCAP would enable targeted searches …

Self assembly advance: self assembled nanofold network

Efforts to link nanotubes have usually begun with the most familiar kind, cylinders whose structure is equivalent to one or more rolled-up sheets of a layered crystal like graphite. Now researchers at Lawrence Berkeley National Laboratory’s National Center for Electron Microscopy (NCEM) and the Christian Albrechts University of Kiel, Germany, have found a completely new …

Other tech: NTT achieves 2.5 Gbps packet transmission

NTT DoCoMo, Japan’s mobile phone giant, has achieved 2.5 gigabits-per-second packet transmission in a fourth-generation radio access field experiment. This speed is 6,510 times faster than the current third-generation FOMA mobile series, the Sankei Shimbun reported Friday.

Detection Of DNA On Nanotubes Offers New Sensing, Sequencing Technologies

Researchers at the University of Illinois at Urbana-Champaign who recently reported that DNA-wrapped carbon nanotubes could serve as sensors in living cells now say the tiny tubes can be used to target specific DNA sequences. Potential applications for the new sensors range from rapid detection of hazardous biological agents to simpler and more efficient forensic …

Other tech: Living taste cells made outside of the body

Researchers from the Monell Chemical Senses Center have succeeded in growing mature taste receptor cells outside the body and for the first time have been able to successfully keep the cells alive for a prolonged period of time (10-14 days). The establishment of a viable long-term model opens a range of new opportunities to increase …

other tech: Disposable Catheters, with MEMS sensors

A unique low cost disposable solid-state catheter that can measure swallowing pressure has been developed by a University of South Australia research team using intelligent manufacturing processes that eliminate the infection risks posed by existing catheters. Believed to be the first of its kind in the world, the catheter is one of the new products …

More space elevator development plans

In March 2006, LiftPort hopes to set up a HALE system in Utah’s Mars DesertResearch Station and maintain it for three weeks. Then, later in thespring, Laine says he wants to test a 2-mile (3.2-km) tether withrobots scaling to at least half way up. Laine aims to produce a functioning space elevator by 2018 – …

update on work towards a space elevator

A robotic lifter, measuring 5-foot-6 (170 centimeters) in length, grabbed onto the ribbon and pulled itself up to altitudes of more than 1,500 feet (460 meters), besting the previous record by 500 feet. Laine is gearing up for a test of a different type. In cooperation with the Mars Desert Research Station and a team …

other tech: Evanescent wave lithography enables optical imaging to smallest-ever level

Yongfa Fan, a doctoral student in RIT’s microsystems engineering Ph.D. program, accomplished imaging rendered to 26 nanometers a size previously possible only via extreme ultraviolet wavelength, Smith says. By capturing images that are beyond the limits of classical physics, the breakthrough has allowed resolution to smaller than one-twentieth the wavelength of visible light, he adds. …
