Technology.am (Oct. 8, 2009) — Researchers led by Robyn Whittaker, at the University of Auckland, looked at four studies: two of text-message only programs and two that used the Internet along with mobile phones to keep up a stream of stop-smoking support.
Studies included about 2,600 smokers of all ages. After pooling study data, reviewers found that participants in text-message programs were about twice as likely not to smoke after six weeks as smokers in control groups.
People in mixed-media programs — cell phone plus Web — were significantly more likely to …
Technology.am (Oct. 8, 2009) — The researchers at North Carolina State University are working to make Dunaliella algae as a fuel source because they grow quickly and can be grown throughout the year, they don’t use up freshwater supplies and can be cultivated in areas where they won’t compete with traditional food crops, such as corn or soybeans.
They provide the potential to create 100 times as much feedstock per acre as conventional crops, says professor Dr. Bill Roberts, at North Carolina State University. They got a $2 million …
Technology.am (Oct. 8, 2009) — University of Missouri researchers are developing a nuclear energy source that is smaller, lighter and more efficient.
“To provide enough power, we need certain methods with high energy density,” said Jae Kwon, assistant professor of electrical and computer engineering at MU.
“The radioisotope battery can provide power density that is six orders of magnitude higher than chemical batteries.”
Kwon and his research team have been working on building a small nuclear battery, currently the size and thickness of a penny, intended to power various …
Technology.am (Oct. 2, 2009) — Taiwanese scientists at north Taiwan’s Hsinchu city, have developed hydrogen-powered mobile phone chargers that can recharge a mobile phone battery in two hours without being plugged.
Hydrogen is a recyclable material. They are hoping that hydrogen-powered device can replace current cell phone recharge systems in 2012.
Taiwan is under pressure to develop new energy sources, as it imports about 98 percent of its energy.
Technology.am (Oct. 2, 2009) — If a bird collides with a plane the consequences can be fatal, not only for aircraft but also for the creature itself. The impact can deform the structure of the aircraft fuselage, causing stresses in the material which can later turn into cracks.
Now sensors in the aircraft skin will detect such damage at an early stage and simplify maintenance and repair work. If they discover any dents or cracks they will send a radio message to a monitoring unit.
The sensors can …
Technology.am (Sept. 29, 2009)– Clemson University researchers have been awarded a $470,000 National Science Foundation grant to study making plug-in hybrid electric vehicles (PHEVs) more efficient to reduce fossil fuel use. They will study integrating the vehicles with infrastructure where they act as probes that generate continuous detailed traffic data.
The hybrid electric vehicles will work with the Vehicle Infrastructure Integration (VII) system, also known as IntelliDrive. It’s an initiative that will improve traffic operations and safety in the future by linking vehicles to their physical surroundings.
The VII systems providing detailed …
Technology.am (Sept. 27, 209) — Gerard Wysocki, a Princeton and Rice University researcher has demonstrated a new method of identifying the gas using lasers and sensors to detect nitric oxide gas, a key player in pollution and human physiology.
In the air, nitric oxide is a serious pollutant. In the body, it plays a role in heart rate, blood flow, nerve signals and immune function. It is so potent that a few molecules of it per billion or trillion molecules of air promote smog, acid rain and depletion of …
Technology.am (Sept. 25, 2009) — SolarCity has announced the installation of four chargers arrayed along the stretch of highway 101 between San Francisco and Los Angeles.
All the four charging stations are located in Salinas, Atascadero, Santa Maria, and San Luis Obispo.
SolarCity has announced the installation of charging stations along highway 101 between San Francisco and Los Angeles. There are four chargers arrayed along the stretch of highway and are located in Salinas, Atascadero, Santa Maria, and San Luis Obispo.
All of the charging stations produce 240V at 70 …
Technology.am (Sept. 24, 2009) — At the Frankfurt Motor show in Germany, Brabus has unveiled the Ultimate High Voltage Concept Electric Car.
The sporty little car is a new model that is an updated version of the Brabus’s electric Smart ED concept.
The sporty little car will do the 0 – 60 km/h (38.5 mph) sprint in 3.7 seconds and 0 – 100 km/h (62 mph) in 9.8 seconds.
These performances are possible due to 61kW (82hp) and 280Nm of peak torque achieved at 0 rpm.
The car features lithium ion batteries and a …
