The sensors contain innovative distributive mechanisms, which enable online situation awareness and adaptive learning based on artificial intelligence.

If these walls could talk… actually, they can. A new project that goes by the acronym GENESI (Green sEnsor Networks for Structural monItoring) is working to give infrastructure the ability to tell us how it feels.

GENESI researchers are creating various sensor that fit inside buildings, tunnels, and bridges. This novel generation of green wireless sensor networks’ main aim is to allow structures to communicate their status.

The sensor device itself combines a low power node platform with a multi-source energy harvester, a small factor fuel cell, and an energy efficient radio. Each sensor has the ability to monitor vibrating strain, displacement, temperature, and soil moisture.

Researchers have investigated a strategy to prevent this “polysulfide shuttling” phenomenon by creating nano-sized sulfur particles, and coating them in silica (SiO₂), otherwise known as glass.

Lithium-sulfur has been a hot topic in battery technology recently. Because of its ability to produce 10 times the amount of energy as a conventional battery, we’ve seen novel innovations such as the all solid state lithium-sulfur battery. Now, the li-sulfur battery is getting a glass coating to further improve its performance.

Researchers at the University of California, Riverside have applied a glass cage-like coating, along with graphene oxide, to the li-sulfur battery. This innovation was developed in order to overcome one of the major issues in commercializing the battery – polysulfides, which cause the battery’s capacity to decrease over its lifetime.

The cathode material traps the polysulfides in a very thin glass cage. Researchers used an organic precursor to construct the trapping barrier.

In an effort to promote the use of alternative energy, the first solar-powered plane is well on its way to making its round-the-world tour.

After 13 year of invention and ingenuity, Swiss pilots Piccard and Andre Borschberg are beginning preparations to launch the tour in less than a week.

Casey Emilius, ECS’s Meetings Coordinator, spotted an article in Inhabitat on an amazing feat in student ingenuity out of Nigeria.

College student Segun Oyeyiola has transformed a Volkswagen Beetle into a wind- and solar- powered car with just $6,000. By using mostly scrap parts donated by friends and family, Oyeyiola was able to keep costs down and skyrocket the renewable efficiency of the car.

The car is fortified by a strong suspension system to hold the weight of the solar panel on the roof and the wind turbine under the hood – which takes advantage of the airflow produced by the car while it’s in motion.

If you haven’t embraced solar energy yet, it may be about time to do so. After all, it is cheaper than grid energy in 42 of the 50 largest cities in the United States.

According to the study “Going Solar in America: Ranking Solar’s Value in America’s Largest Cities,” a fully financed solar system costs less than residential grid energy purchased in over 80 percent of the largest U.S. cities. Additionally, 9.1 million single-family homeowners live in a place where their utility bill outpaces what solar would cost.

The falling cost of solar panels and solar fuel cells is largely driven by, in part, research into new materials and developments in the sciences. Check out a few interesting reads on solar energy from the ECS Digital Library:

• “Photobioelectrochemistry: Solar Energy Conversion and Biofuel Production with Photosynthetic Catalysts” (It’s open access!)
• “The Role of Energy Levels in Semiconductor-Electrolyte Solar Cells“
• “Photoelectrolysis and In Situ Storage of Solar Energy” (Throwback to 1989!)

When it comes to battery research and technology, people are constantly looking toward the lithium-ion battery to see the next big breakthrough. However, researchers at the chemical company BASF are showcasing and older battery type as a strong competitor against the li-ion.

BASF researchers are taking the nickel-metal hydride battery (NiMH) and giving it a boost to lead to cheaper electric cars. The assumption for electric car makers it that improvements in the lithium-ion battery will make cars cheaper and extend their driving range. While that may be true, the NiMH may also be able to do this with a little improvement.

The chemical company has already been able to double the amount of energy these old battery types can store, thus making them comparable to the lithium-ion. Researchers also state that there is still much room for improvement – with the potential to increase energy storage by an additional eight times.

Further, the batteries are set to cost roughly half as much as the cheapest lithium-ion battery.

The newly developed silicon nanofiber structure allows the battery to be cycled hundreds of times without significant degradation.

Electric cars and personal electronics may get the battery boost they need with this new development in lithium-ion batteries.

Researchers from the University of California, Riverside have created silicon nanofibers that are 100 times thinner than human hair, which will provide the potential to boost the amount of energy that can be delivered per unit weight of the batteries.

The research has been detailed in the paper “Towards Scalable Binderless Electrodes: Carbon Coated Silicon Nanofiber Paper via Mg Reduction of Electrospun SiO₂ Nanofibers.”

This from University of California, Riverside:

The nanofibers were produced using a technique known as electrospinning, whereby 20,000 to 40,000 volts are applied between a rotating drum and a nozzle, which emits a solution composed mainly of tetraethyl orthosilicate (TEOS), a chemical compound frequently used in the semiconductor industry. The nanofibers are then exposed to magnesium vapor to produce the sponge-like silicon fiber structure.

The researchers are also investigating the textured graphene surfaces for 3D sensor applications.

The infamous wonder material is becoming even more wonderful with this new development from the University of Illinois at Urbana-Champaign (UIUC).

Scientist from UIUC have developed a novel process to transform flat graphene from 2D to 3D with a simple and commercially available single-step process. The process uses thermally activated shape-memory polymer substrates to texture the graphene and “crumple” it to give it an increased surface space.

With the easy of this process and the increased surface space of the material, there is a potential for electronics and biomaterials to advance at a much faster rate.

For the past several years, there has been one image that has been central to the climate change debate: the infamous “hockey stick” graph.

Since the graph appeared in the paper “Northern hemisphere temperatures during the past millennium: Inferences, uncertainties, and limitation,” Michael Mann has been hard at work defending his research.

“The hockey stick graph became a central icon in the climate wars,” Mann said at the Feb. 11 meeting of the American Association for the Advancement of Science. “The graph took on a life of its own.”

The graph gained notoriety when the Intergovernmental Panel on Climate Change published the image and starting using it to drive home the message of climate change. The graph still remains an ever-present part of the climate debates.
