The researchers from this country has developed the world's smallest computer "Michigan Micro Mote"? |
| Answer» Researchers at the University of Michigan (UM) in the US have developed the world's smallest computer "Michigan Micro Mote". It measures just 0.3 mm and could help find new ways to monitor and treat cancer. In addition to the RAM and photovoltaics, the new micro computing device has processors and wireless transmitters and receivers. Since they are too small to have conventional radio antennae, they receive and transmit data with visible light. A base station provides light for power and programming, and it receives the data. Designed as a precision temperature sensor, the computer can report temperatures in minuscule regions - such as a cluster of cells - with an error of about 0.1 degrees Celsius. | |

The researchers from this institute have developed cheaper organic solar cells using vitamin B12 derivative, recently. |
| Answer» The researchers at the Indian Institute of Science Education and Research (IISER) Bhopal have developed cheaper and more flexible organic solar cells using a synthetic derivative of vitamin B12. An organic solar cell is made up of acceptor and donor materials. The donor absorbs light from solar radiation and the harvested energy is passed to the electrodes with the help of the acceptor. In the present study, the researchers synthesized the donor using an artificial aromatic chemical (corrole) which has a similar structure to the corrin ring in vitamin B12. The artificially synthesised corrole (Cor-BODIPY) absorbs light much like porphyrin in natural chlorophyll. Currently, corroles are used as sensors, catalysts and in biomedical imaging. This is the first study wherein a corrole has been utilised for a bulk heterojunction solar cell as a donor material. | |
