The best material to keep carbon dioxide from natural gas wells from fouling the atmosphere may be a derivative of asphalt, according to Rice Univ. scientists. The Rice laboratory of chemist James Tour followed up on last year’s discovery of a “green” carbon capture material for wellhead sequestration with the news that an even better compound could be made cheaply in a few steps from asphalt.
Researchers have demonstrated, for the first time, a method to successfully predict pressure-dependent chemical reaction rates, an important breakthrough in combustion and atmospheric chemistry that is expected to benefit auto and engine manufacturers, oil and gas utilities and other industries that employ combustion models.
The Center for Nanoparticle Research at the Institute for Basic Science has succeeded in proposing a new method to enhance fuel cell efficiency with the simultaneous removal of toxic heavy metal ions. The direct methanol fuel cell (DFMC) has been a promising energy conversion device for electrical vehicles and portable devices. However, the inevitable carbon monoxide (CO) poisoning is one of the main factors reducing its performance.
In 2007, Google unleashed a fleet of cars with roof-mounted cameras to provide street-level images of roads around the world. Now Massachusetts Institute of Technology spinout Essess is bringing similar “drive-by” innovations to energy efficiency in homes and businesses.
Hydrogen fuel is a promising source of clean energy that can be produced by splitting water into hydrogen and oxygen gas. The reaction is difficult but achievable with the help of a catalyst. However, current catalysts lack the efficiency required for water splitting to be commercially competitive. Recently, however, scientists have identified one such catalyst, iron-doped nickel oxide.
A team from the University of Arizona and eight Southwestern electric utility companies has built a pioneering web portal that provides insight into renewable energy sources and how they contribute to the region’s electricity grid.
A new catalytic process is able to convert what was once considered biomass waste into lucrative chemical products that can be used in fragrances, flavorings or to create high-octane fuel. A team of researchers from Purdue Univ.'s Center for Direct Catalytic Conversion of Biomass to Biofuels, or C3Bio, has developed a process that uses a chemical catalyst and heat to spur reactions that convert lignin into valuable chemical commodities.
The 50,000-sf New Technology and Learning Center for Bristol Community College, Fall River, Mass., brings together disparate programs—chemistry, biology, medical and dental education—holding energy-dense uses, including 18 fume hoods, high plug loads and specific ventilation and lighting requirements.
With the recent news about Ebola, MERS, extremely drug-resistant TB and other emerging and re-emerging diseases, the world-wide need for high-containment laboratories is at an all-time high. These laboratories are highly complex buildings that serve as a barrier between the dangerous pathogens handled in the laboratory and the surrounding environment.
In the fight against global warming, carbon capture is gaining momentum, but standard methods are plagued by toxicity, corrosiveness and inefficiency. Using a bag of chemistry tricks, Cornell Univ. materials scientists have invented low-toxicity, highly effective carbon-trapping “sponges” that could lead to increased use of the technology.
People who own all-electric cars where coal generates the power may think they are helping the environment. But a new study finds their vehicles actually make the air dirtier, worsening global warming. Ethanol isn't so green, either. The study examines environmental costs for cars' entire lifecycle, including where power comes from and the environmental effects of building batteries.
The Internet is a massive place, linking billions of devices which share data that should exceed the zettabyte mark by 2016. Even as data transfer grows, the number of devices connected to the Internet will soon experience a geometric rise as well.
Differences in local market conditions and policies, and other factors, particularly the size of the system, can lead to wide disparities in what consumers across the U.S. pay to install solar energy systems on their homes or small businesses, according to a recent study published by Lawrence Berkeley National Laboratory. This translates into thousands of dollars difference in the price of comparable solar energy systems around the U.S.
Stanford University's Precourt Institute for Energy, Precourt Energy Efficiency Center and TomKat Center for Sustainable Energy have awarded eight seed grants totaling about $1.5 million for promising new research in clean technology and energy efficiency.
The discovery of a new form of ice could lead to an improved understanding of our planet’s geology, potentially helping to unlock new solutions in the production, transportation and storage of energy. Ice XVI, the least dense of all known forms of ice, has a highly symmetric cage-like structure that can trap gaseous molecules to form compounds known as clathrates or gas hydrates.
Scientists are developing a new kind of “smart window” that can block out heat when the outside temperatures rise. The advance could one day help consumers better conserve energy on hot days and reduce electric bills.
During the 2014 R&D 100 Awards event, R&D Magazine expanded the banquet to hold four technology panels during the day. The last panel of the day focused on energy/environmental solutions and the innovation behind four R&D 100-winning technologies and the complexity of bringing such technologies to the market.
A groundbreaking research project by the GW4 Alliance aims to clean up water from a Cornish tin mine, using algae to harvest the precious heavy metals and produce biofuel at the same time. GW4 brings together the South West and Wales’ four leading, research-intensive universities: Bath, Bristol, Cardiff and Exeter.
A new electrode design for lithium-ion batteries has been shown to potentially reduce the charging time from hours to minutes by replacing the conventional graphite electrode with a network of tin-oxide nanoparticles. Batteries have two electrodes, called an anode and a cathode. The anodes in most of today's lithium-ion batteries are made of graphite.
An efficient method to harvest low-grade waste heat as electricity may be possible using reversible ammonia batteries, according to Penn State Univ. engineers. Low-grade waste heat is an artifact of many energy-generating methods. In automobiles, waste heat generated in winter is diverted to run the vehicle heating system, but in the summer, that same waste heat must be dissipated to the environment.
Stanford Univ. engineers have invented a revolutionary coating material that can help cool buildings, even on sunny days, by radiating heat away from the buildings and sending it directly into space. The heart of the invention is an ultra-thin, multi-layered material that deals with light, both invisible and visible, in a new way.
As solar panels become less expensive and capable of generating more power, solar energy is becoming a more commercially viable alternative source of electricity. However, the photovoltaic cells now used to turn sunlight into electricity can only absorb and use a small fraction of that light, and that means a significant amount of solar energy goes untapped. A new technology epresents a first step toward harnessing that lost energy.
The use of renewable energy in the U.S. could take a significant leap forward with improved storage technologies or more efforts to “match” different forms of alternative energy systems that provide an overall more steady flow of electricity. Historically, a major drawback to the use and cost-effectiveness of alternative energy systems has been that they are too variable. This lack of dependability is costly and inefficient.
Researchers at KU Leuven’s Centre for Surface Chemistry and Catalysis have successfully converted sawdust into building blocks for gasoline. Using a new chemical process, they were able to convert the cellulose in sawdust into hydrocarbon chains. These hydrocarbons can be used as an additive in gasoline, or as a component in plastics.
Who knew Blu-ray discs were so useful? Already one of the best ways to store high-definition movies and television shows because of their high-density data storage, Blu-ray discs also improve the performance of solar cells, according to new research from Northwestern Univ.
