Brazil world leader in sugarcane and ethanol knowledge and technology

 
Mini 018FAPESP – Brazil is the largest producer of ethanol from sugarcane in the world and occupies the leadership in technology for its production. The advances in technology have meant that its productivity is outstanding and the costs of production much lower than those of its international competitors. This leadership is due to the long work of many years undertaken by researchers in institutions of higher education and research and in private enterprises, which has resulted in a valuable baggage of knowledge and technology on sugarcane and its derivatives and on the process of ethanol manufacture.

A new use for rice — lithium ion batteries

1Researchers in Korea report that rice husks — the tough, protective layer covering a rice kernel — are ideal sources of silicon for high-capacity lithium battery anodes. Their findings are published in PNAS Early Edition.

Husks protect rice kernels from bacteria and insects, while allowing air and moisture to penetrate through tiny pores in layers of silica. This three dimensional structure maintained its shape even as the researchers processed the silica husks into purified silicon.

Grassroot-level innovations may hold the key to global challenges

By Duncan Garde, Agustina Memoli and Paulina Polak

rice farmerThe Guardian – Low tech, grassroot-level innovations may hold the key to overcoming some of the resource challenges we face today; and we might be missing them. The solutions below are some exceptional examples of grassroots level innovations. The question is – how many other potential world changing solutions have remained in obscurity at source, never replicating sufficiently to make a significant change? ….>>Continue Reading<<

Plant-powered planes show promise

11BBC – To the eye, there was nothing remarkable about the aging Falcon 20 jet as it took off from Ottawa International airport in Canada at the end of October in 2012. But the twin-engined, 10-seater plane was in the process of making aviation history.

After a short flight that saw it climb to 30,000 ft (9,000m) over the capital city, the plane touched back down at the airport to secure its world first.

Three-dimensional fruit

4. FapespReturnable packaging, custom-tailored to properly hold fruit such as persimmons, mangos, papayas and strawberries, thus reducing losses in their shipment after harvest, was developed by the National Institute of Technology (INT) in partnership with the Center for Food Technology at the Brazilian Agricultural Research Corporation (Embrapa). Losses of fruits and vegetables as a result of the systems currently in use, such as wooden, cardboard or plastic crates, is close to 39%, according to data from Embrapa. “We created the packaging according to the shape of the fruit,” says Marcos Henrique Garamvolgyi, project designer in the industrial design division of the INT. The process of developing the packaging involves making a digital image of the fruit using a 3D scanner and performing tests with samples printed on rapid prototype machines, allowing for the creation and testing of containers even outside of the fruit harvest periods. The packaging is made of plastic and vegetable fiber and its base is fordable so it can be returned to the producer. The tray is thin and the cavities are the exact size of the fruit.

How to build science capacity

By Lim Chuan Poh
Nature – Last year, Singapore celebrated 20 years of government investment in science and technology. From 1991 to 2010, public expenditure on research and development doubled, from 0.4% to 0.8% of the gross domestic product. The number of research scientists in the public sector quadrupled, to nearly 13,000.
One great success is our scholarship programme. Since 2001, it has enabled talented young Singaporeans to pursue education and training — from the undergraduate level to the postdoctoral — in leading universities and labs around the world. These students then return to Singapore to continue their research for up to six years. Working abroad, they see first hand that a rich milieu is crucial to the pursuit of excellent science. They bring back new networks and collaborations.
