BitCoin, Cryptocurrency, and Blockchain Technology — FACTOM

Quoted: “The Factom team suggested that its proposal could be leveraged to execute some of the crypto 2.0 functionalities that are beginning to take shape on the market today. These include creating trustless audit chains, property title chains, record keeping for sensitive personal, medical and corporate materials, and public accountability mechanisms.

During the AMA, the Factom president was asked how the technology could be leveraged to shape the average person’s daily life.”

Kirby responded:

“Factom creates permanent records that can’t be changed later. In a Factom world, there’s no more robo-signing scandals. In a Factom world, there are no more missing voting records. In a Factom world, you know where every dollar of government money was spent. Basically, the whole world is made up of record keeping and, as a consumer, you’re at the mercy of the fragmented systems that run these records.”

Preamble: Bitcoin 1.0 is currency — the deployment of cryptocurrencies in applications related to cash such as currency transfer, remittance, and digital payment systems. Bitcoin 2.0 is contracts — the whole slate of economic, market, and financial applications using the blockchain that are more extensive than simple cash transactions like stocks, bonds, futures, loans, mortgages, titles, smart property, and smart contracts

Bitcoin 3.0 is blockchain applications beyond currency, finance, and markets, particularly in the areas of government, health, science, literacy, culture, and art.

Morphing material could allow robots to switch between hard and soft states

Posted by in category: materials

Kurweil AI

A new Terminator T-1000 robot-style material made of wax and foam — and capable of switching between hard and soft states — could be used to build morphing surgical robots that move through the body to reach a desired location without damaging organs or vessels along the way.

Robots built from the material, described in a new paper in the journal Macromolecular Materials and Engineering, could also be used in search-and-rescue operations to squeeze through rubble looking for survivors, says Anette Hosoi, an MIT professor of mechanical engineering and applied mathematics who led the research team.

A graphene replacement made from plastic

Posted by in category: materials

Kurzweil AI

A team of Korean researchers has synthesized hexagonal carbon nanosheets similar to graphene, using a polymer. The new material is free of the defects and complexity involved in producing graphene, and can substitute for graphene as transparent electrodes for organic solar cells and in semiconductor chips, the researchers say.

Professor of Chemistry Turns India’s Plastic Trash into Useable Roadways

Scenes from the movie Slumdog Millionaire accurately depict India’s latest consumer-influenced economy. Tree groves are littered with a rainbow color of plastic bags like some kind of ominous carnival wreckage. Plastic bottles, candy wrappers, and other ‘garbage’ liters the streets in a land where city officials have long forsaken their duties of providing a pristine infrastructure to its inhabitants, but a professor of chemistry in Madurai, India thinks that the trash lining his country’s roads and fields could be utilized as a ‘wonderful resource,” transforming common plastic liter, from thicker acrylics to bottles and grocery bags, into a substitute for bitumen in asphalt.

The ‘Plastic Man,’ as Rajagopalan Vasudevan is known in India, travels throughout the country instructing engineers how to apply his technology to recycle the trash copiously littering streets from Punjab to Tamil Nadu. To date, more than 3000 miles of plastic roads have been laid in at least 11 states.

A transistor material intended to replace silicon by 2024

Posted by in categories: engineering, materials

Kuzweil AI

USC Viterbi School of Engineering researchers have developed a flexible, transparent, energy-efficient, lower-cost hybrid design that could replace silicon as the traditional transistor material used in electronic chips.

The new design, described in a paper recently published in Nature Communications, combines carbon nanotube thin-film transistors with thin-film transistors comprised of indium, gallium and zinc oxide (IGZO).

Electrical engineering professor Dr. Chongwu Zhou and USC Viterbi graduate students Haitian Chen, Yu Cao, and Jialu Zhang developed this energy-efficient circuit by integrating carbon nanotube (CNT) thin film transistors (TFT)

The inclusion of IGZO thin film transistors was necessary to provide power efficiency to increase battery life. If only carbon nanotubes had been used, the circuits would not be power-efficient.
