To support the goal of making the system available worldwide it had to be simple enough for field researchers to use consistently able to be transported in backpacks to locations without electricity
In the same forests the team also placed traps configured with decoys bearing a 4000-volt charge to electrocute
if the voltage was applied to the decoys. According to Domingue the light-scattering properties of the beetle's shell--which the team experimentally demonstrated using a white laser--made the nano-bioreplicated decoys more lifelike and therefore more attractive to males than the non-textured 3d printed decoy.
The holy grail of wireless communications is to go both fast and far said lead researcher Edward Knightly professor and chair of Rice's Department of Electrical and Computer Engineering.
It was made possible by the Rice-based Nanojapan program through which American undergraduates conduct summer research internships in Japanese labs. Even a single molecule of a foreign substance can contaminate graphene enough to affect its electrical and optical properties
Unfortunately (and perhaps ironically) that includes electrical contacts. Traditionally in order to measure conductivity in a material one has to attach contacts
and then do said electrical measurements Kono whose lab specializes in terahertz research. But our method is contact-less.
Laser pulses generated coherent bursts of terahertz radiation through a built-in surface electric field of the indium phosphide substrate that changed due to charge transfer between the graphene and the contaminating molecules.
and study effects of the focused laser beam has on these materials. â#Micropatterns â#drawnâ##on Mos2 films could enhance electrical conductivity
Interestingly they also found that the electrical conductivity and photoconductivity of the modified material had increased by more than 10 times and about five times respectively.
Further researchthe fast growing field of electronics and optoelectronics demands precise material deposition with application-specific optical electrical chemical and mechanical properties.
Use of porous silicon oxide reduces forming voltage, improves manufacturabilityrice University's breakthrough silicon oxide technology for high-density next-generation computer memory is one step closer to mass production thanks to a refinement that will allow manufacturers to fabricate devices at room temperature with conventional
The basic concept behind resistive memory devices is the insertion of a dielectric material--one that won't normally conduct electricity--between two wires.
When a sufficiently high voltage is applied across the wires a narrow conduction path can be formed through the dielectric material.
It can be manufactured at room temperature has an extremely low forming voltage high on-off ratio low power consumption nine-bit capacity per cell exceptional switching speeds and excellent cycling endurance.
First the porous material reduced the forming voltage--the power needed to form conduction pathways--to less than two volts a 13-fold improvement over the team's previous best and a number that stacks up against competing RRAM technologies.
and just drop down electrodes without having to fabricate edges Tour said. When we made our initial announcement about silicon oxide in 2010 one of the first questions
Tour said the latest developments with porous silicon oxide--reduced forming voltage elimination of need for edge fabrication excellent endurance cycling
's power plants. Our technique allows one to specifically remove carbon dioxide at the source. It doesn't have to be transported to a collection station to do the separation he said.

Coal-fired power plants produce a lot of pollution so any measures that will reduce our combustion of coal will also help us to fight air pollution.
This will be particularly important for China he said which has been plagued by skyrocketing air pollution from coal power plants used to fuel its industrial expansion.
Experts estimate that a quarter of a million people die prematurely each year in China because of air pollution from the country's coal-fired power plants.
when solar power was more of a novelty source of energy for individuals who were too far from power lines to get conventional electricity from the grid.
Today we build large power plants that can supply entire cities with renewable electricity. In fact today we install the equivalent of 100 large coal-fired power plants--the same capacity in renewables--every year he said.
However we haven't started phasing out the coal-fired power plants so this needs to happen too.
The good news is that the WG III report presents a full range of options for action.

That has Dong leading a research team that includes Namrata Vaswani an Iowa State associate professor of electrical and computer engineering;
whether an intervention had a significant effect said Baraniuk the Victor E. Cameron Professor of Engineering in the Department of Electrical and Computer Engineering and director of Rice's RDLS.
and moving parts and electrical engineers to design control systems Linden said. Tests have shown that each of the eight fiber-optic cables can produce between 80 and 90 watts of energy meaning the whole system can deliver up to 700 watts of energy into the reaction chamber said Linden.
In late December tests at CU-Boulder showed the solar energy directed into the reaction chamber could easily boil water
Corn cubs and sugar canes are in fact plant parts that can also be used directly as food so there is a great public resistance to accept producing this kind of bioethanol.
#Electrical generator uses bacterial spores to harness power of evaporating watera new type of electrical generator uses bacterial spores to harness the untapped power of evaporating water according to research conducted at the Wyss Institute of Biologically Inspired
Its developers foresee electrical generators driven by changes in humidity from sun-warmed ponds and harbors.
and that movement can be harvested to generate electricity. If this technology is developed fully it has a very promising endgame said Ozgur Sahin Ph d. who led the study first at Harvard's Rowland Institute later at the Wyss Institute
But until now no one has tapped that energy to generate electricity. As Sahin pursued the idea of a new humidity-driven generator he realized that Mahadevan had been investigating similar problems from a physical perspective.
Then he built a simple humidity-driven generator out of Legosâa miniature fan a magnet and a spore-coated cantilever.
As the cantilever flips back and forth in response to moisture it drives a rotating magnet that produces electricity.
If changes in humidity could be harnessed to generate electricity night and day using a scaled up version of this new generator it could provide the world with a desperately needed new source of renewable energy.

you can't use solar panels for that. I'm keenly interested in renewable energy. We started looking around
We have demand for both thermal energy as well as electricity. This fuel can be used to drive generators, much more efficient than the steam process.
and instead of purchasing electricity generated outside our state from fossil fuels, we're pouring our dollars into our local economy.
We're pretty comfortable that this technology is able to produce electricity at 12 cents per kilowatt-hour.
Firm electrical power. You can't do that with solar you can't do that with wind.
how can we accelerate the decline to achieve the elusive $1/watt price where clean technologies are price-competitive with fossil fuels?
We think that even at $1. 50 a watt, this will go viral, he said.

In the U s.,49 percent of the water used in the industrial market goes to generate power for thermal power plants:
A big power plant uses a boatload of water. The primary use is to cool those processes--the big hyperbolic cooling towers.
It takes about 5 million gallons a day of water for a 1, 000 megawatt power plant.
Why is there such water demand from power plants? Can't they reuse it? JF: Often what happens is the water that leaves the plant is less than
but a lot more expensive than a coal power plant. Early on, it needed incentives to get started. Similarly
