Waste coffee used as fuel storage

Scientists have developed a simple process to treat waste coffee grounds to allow them to store methane


2015-09-02
(Press-News.org) Scientists have developed a simple process to treat waste coffee grounds to allow them to store methane. The simple soak and heating process develops a carbon capture material with the additional environmental benefits of recycling a waste product. The results are published today, 03 September 2015, in the journal Nanotechnology. Methane capture and storage provides a double environmental return - it removes a harmful greenhouse gas from the atmosphere that can then be used as a fuel that is cleaner than other fossil fuels. The process developed by the researchers, based at the Ulsan National Institute of Science and Technology (UNIST), South Korea, involves soaking the waste coffee grounds in sodium hydroxide and heating to 700-900 °C in a furnace. This produced a stable carbon capture material in less than a day - a fraction of the time it takes to produce carbon capture materials. "The big thing is we are decreasing the fabrication time and we are using cheap materials," explains Christian Kemp, an author of the paper now based at Pohang University of Science and Technology, Korea. "The waste material is free compared compared to all the metals and expensive organic chemicals needed in other processes - in my opinion this is a far easier way to go." Kemp found inspiration in his cup of coffee whilst discussing an entirely different project with colleagues at UNIST. "We were sitting around drinking coffee and looked at the coffee grounds and thought 'I wonder if we can use this for methane storage?'" he continues. The absorbency of coffee grounds may be the key to successful activation of the material for carbon capture. "It seems when we add the sodium hydroxide to form the activated carbon it absorbs everything," says Kemp. "We were able to take away one step in the normal activation process - the filtering and washing - because the coffee is such a brilliant absorbant." The work also demonstrates hydrogen storage at cryogenic temperatures, and the researchers are now keen to develop hydrogen storage in the activated coffee grounds at less extreme temperatures.

Biodiversity belowground is just as important as aboveground

Biodiversity belowground is just as important as aboveground
2015-09-02
Although most of the world's biodiversity is below ground, surprisingly little is known about how it affects ecosystems or how it will be affected by climate change. A new study demonstrates that soil bacteria and the richness of animal species belowground play a key role in regulating a whole suite of ecosystem functions on Earth. The authors call for far more attention to this overlooked world of worms, bugs and bacteria in the soil. Ecosystem functions such as carbon storage and the availability of nutrients are linked to the bugs, bacteria and other microscopic ...

Cellular recycling complexes may hold key to chemotherapy resistance

2015-09-02
CAMBRIDGE, Mass. (September 2, 2015) - Altering the protein recycling complexes in human cells, including cancer cells, allows the cells to resist treatment with a class of drugs known as proteasome inhibitors, according to Whitehead Institute scientists. "This is why some cancers can be so difficult to treat with chemotherapy, because the cells can be in different states--some sensitive to treatment and some resistant to treatment, all in the same tumor," says Sandro Santagata, a former visiting scientist in the lab of Whitehead Member Susan Lindquist. Santagata is now ...

Male seahorse and human pregnancies remarkably alike

Male seahorse and human pregnancies remarkably alike
2015-09-02
Their pregnancies are carried by the males but, when it comes to breeding, seahorses have more in common with humans than previously thought, new research from the University of Sydney reveals. Seahorses are famed for being part of the only family in the animal kingdom (Syngnathidae) in which the male is responsible for pregnancy. What hasn't been known until now is the degree to which male seahorses nourish and protect their embryos in their brood pouch during the 24-day gestation period. Findings co-authored by Dr Camilla Whittington from the University's School of ...

Scientists discover a common diabetes drug could prevent hemorrhage and fatal blood loss

2015-09-02
A new study, published today in the British Journal of Pharmacology, by scientists from Royal Holloway, University of London, St George's, University of London and University of Surrey have identified that a drug related to commonly used diabetes treatments provides protection against terminal blood loss. Massive blood loss often leads to death, and when blood transfusions are unavailable, drugs are currently being tested that can keep people alive until they get to hospital. Understanding how these drugs work, and finding improved drugs, has up to now proved difficult. ...

When stroke patients undergo surgery to remove blood clots, what anesthesia works best?

2015-09-01
MAYWOOD, Ill. - In carefully selected patients, minimally invasive surgery is enabling physicians to stop strokes in their tracks. And as more stroke patients undergo such procedures, physicians are debating the best way to anesthetize them. Should patients be put under general anesthesia, rendering them unconscious and motionless? Or should they undergo conscious sedation, in which they remain conscious, but are sedated and do not feel pain? In the September, 2015 issue of the Journal of Stroke and Cerebrovascular Diseases, Loyola University Medical center anesthesiologists ...

Self-driving golf carts

2015-09-01
At the International Conference on Intelligent Robots and Systems in September, members of the Singapore-MIT Alliance for Research and Technology (SMART) and their colleagues will describe an experiment conducted over six days at a large public garden in Singapore, in which self-driving golf carts ferried 500 tourists around winding paths trafficked by pedestrians, bicyclists, and the occasional monitor lizard. The experiments also tested an online booking system that enabled visitors to schedule pickups and drop-offs at any of 10 distinct stations scattered around the ...

Surge in Bicycle Injuries to Riders Over 45

2015-09-01
The incidence of bicycle accidents has increased significantly in the U.S. in recent years, with many serious injuries occurring among riders older than 45, according to a new study led by UC San Francisco. The researchers used a national injury surveillance database to study trends in bicycle injuries from 1998 to 2013. They found that the rate of hospital admissions associated with bicycle injuries more than doubled during that timeframe, especially with head and torso injuries. Altogether, the proportion of injuries occurring to riders above age 45 rose 81 percent, ...

Ancient hybridization key to domestic dog's origin, wolf conservation efforts

2015-09-01
KNOXVILLE--The ancestry of man's best friend may be more complicated than its furry coat and soulful eyes betray. Understanding the evolutionary history of the domesticated dog may ultimately help protect endangered wolves, according to a study from the University of Tennessee, Knoxville. Vladimir Dinets, research assistant professor of psychology, has published an overview examining the confusing and often misunderstood system used to classify dogs and related animals such as wolves and jackals. He has proposed a logical and scientifically sound classification scheme ...

New international standards needed to manage ocean noise

2015-09-01
DURHAM, N.C. -- As governments and industries expand their use of high-decibel seismic surveys to explore the ocean bottom for resources, experts from eight universities and environmental organizations are calling for new global standards and mitigation strategies. Their goal is to minimize the amount of sound the surveys produce and reduce risks the surveys and other underwater human noise pollution poses to vulnerable marine life. Firms and agencies conducting the surveys would benefit from these new measures, the experts assert, because instead of having to navigate ...

The more the merrier for animals that synchronize their behavior

2015-09-01
BUFFALO, N.Y. - Social interaction could be the mechanism that allows animals living in groups to synchronize their activities, whether it's huddling for warmth or offering protection from predators. This social presence affects the daily rhythm of activity and rest, and the larger the group, the greater the likelihood of synchronization, according to a study published recently in the journal Biology Letters. "At least in mice, and perhaps in other animals, this study shows quite dramatic synchrony amongst groups of animals that can only be explained by social interactions," ...
