Nanodot-based smartphone battery that recharges in 30 seconds showcased

See on Scoop.itCuriosopernatura

Israeli startup StoreDot recently demonstrated the prototype of a nanodot-based smartphone battery it claims can fully charge in just under 30 seconds. With the company having plans for mass production, this technology could change the way we interact with portable electronics, and perhaps even help realize the dream of a fast-charging electric car.

‘In essence, we have developed a new generation of electrodes with new materials – we call it MFE – Multi Function Electrode,” StoreDot CEO Doron Myersdorf said. “On one side it acts like a supercapacitor (with very fast charging), and on the other is like a lithium electrode (with slow discharge). The electrolyte is modified with our nanodots in order to make the multifunction electrode more effective.”

 

The company says that unlike other nanodot and quantum-dot technologies that are heavy metal based, making them toxic, its nanodots are made from a vast range of bio-organic raw materials that are environmentally-friendly. These materials are also naturally abundant, and the nanodots employ a basic biological mechanism of self-assembly, making them cheap to manufacture.

 

Self-discharge characteristics are similar to those of lithium-ion cells and, for its first prototype, the company targeted the approximate capacity of a smartphone battery (around 2,000 mAh).

Clean Energy Can Provide Jobs And Security

A new report from the International Renewable Energy Agency (IRENA) says the renewable energy industry is responsible for 615,000 jobs in the United States. That’s hundreds of thousands of Americans working to provide this country with clean energy from wind, sun and plants. It’s the military vet in Kansas putting her hydraulics knowledge to work in her new job servicing 300-foot-tall wind turbines. It’s the former glass maker in Toledo, Ohio, who’s now manufacturing solar panels. It’s the farmer who’s got a new buyer in the biofuel plant just across the county line. It’s engineers and managers and truckers and technicians in nearly every state in the nation.

Renewable energy development is making a difference in this country, bringing sorely needed jobs and revenue to communities, while protecting clean air and clean water. Clean, renewable energy is working for us. That’s why so many Americans, from all political stripes, want to see more of it.

A recent national poll found that voters preferred investing in clean energy and efficiency over traditional fossil fuel energy by a margin of nearly 2-to-1. In Kansas, arecent poll found overwhelming support for clean, renewable energy and the government policies that encourage its growth. Roughly three-quarters of Republicans and Independents, and 82 percent of Democrats, support the state’s Renewable Portfolio Standard, which requires that utilities generate 20 percent of their energy from renewable sources by 2020. In fact, two-thirds of voters said they would support increasing the state’s standard to 25 percent. Nine out of ten poll respondents believed that using renewable energy is the right thing to do for the future of Kansas and the country.

Communities in Kansas are not alone in reaping the benefits of clean, renewable energy. According to preliminary analysis from Environmental Entrepreneurs (E2), more than 78,600 clean energy and clean transportation jobs were announced across the country in 2013. Over the past two years combined, E2 has tracked announcements that could create more than 186,500 jobs.

Federal tax policies–such as the production tax credit (PTC) for wind energy, as well as energy efficiency tax incentives for buildings, equipment and appliances— are saving money and creating tens of thousands of jobs while also reducing dangerous carbon pollution that causes climate change and health problems. Congress allowed clean energy tax credits to expire last year: it needs to renew them.

In addition to creating thousands of jobs in the wind energy industry alone, clean energy tax credits save billions of dollars for taxpayers by helping make our homes, schools and office buildings more efficient, and making everyday appliances and equipment use less energy. Energy efficiency, of course, is the cleanest energy of all—there’s nothing cleaner than the energy we don’t use—and it drives job growth as well. In Ohio, for example, utility efficiency efforts alone have created 3,800 jobs , and are expected to create 32,000 jobs by 2025. Federal energy efficiency standards for appliances have generated 340,000 jobs as of 2010, according to the American Council for an Energy Efficient Economy.

Clean energy is one of those issues that we can all rally around. We all want to breathe clean air and drink clean water. We all want to keep the lights on. We’d all like to avoid a future of more frequent, costly extreme weather, from crippling snowstorms in the South, and exhausting drought in the West, to dangerous hurricanes in the East and deadly floods in the Midwest. And we want a strong economy with good jobs, too.

Americans are looking to clean renewable energy because it provides so many of the solutions people are looking for—jobs, environmental protection, reliability, security. With the right policies in place to support the growth of renewable energy, we can continue to move toward a future of 100 percent clean energy.

Retina cells 3D printed for the first time

See on Scoop.itAmazing Science

The ability to arrange cells into highly defined patterns and structures has recently elevated the use of 3D printing in the biomedical sciences to create cell-based structures for use in regenerative medicine.


A group of researchers from the UK have used 3-D biomedical printing to successfully print new eye cells, making it the first time the technology has been used successfully to print mature central nervous system cells. The breakthrough could lead to the production of artificial tissue grafts made from the variety of cells found in the human retina and may aid in the search to cure blindness.


Experts at the University of Cambridge printed two types of cells – ganglion cells and glial cells – derived from adult rat retinas. Ganglion cells transmit information from the eye to parts of the brain, while glial cells provide support and protection for neurons.


Co-authors of the study Professor Keith Martin and Dr Barbara Lorber, from the John van Geest Centre for Brain Repair, University of Cambridge, said: “The loss of nerve cells in the retina is a feature of many blinding eye diseases. The retina is an exquisitely organised structure where the precise arrangement of cells in relation to one another is critical for effective visual function”.


In their study, the researchers used a single nozzle piezoelectric inkjet printer that ejected the cells through a sub-millimetre diameter nozzle when a specific electrical pulse was applied. The driving waveform was defined by a PC-driven generator. “We plan to extend this study to print other cells of the retina and to investigate if light-sensitive photoreceptors can be successfully printed using inkjet technology. In addition, we would like to further develop our printing process to be suitable for commercial, multi-nozzle print heads,” Professor Martin concluded. His goal is to make living tissues using multiple nozzles so that different types of cells could be printed from different nozzles at the same time.


The study has been detailed in a paper published in Biofabrication.
