Wed 26 Mar 2014. Scientists develop silicon cells capable of absorbing infrared radiation from the sun. Researchers have developed a silicon photovoltaic cell capable of turning infrared radiation into electricity. The sun is an inexhaustible source of energy which well-exploited, could solve many of the energy suply problems we have today. The photovoltaic cell, commonly known as solar cell, is a device capable of turning solar light into electricity. However, there are many obstacles that prevent a massive use, such as a relatively high cost (0.02 euros per watt generated) and the low efficiency of silicon based solar cells, around 17 per cent.

Mon 24 Mar 2014.Y-90 provides new, safe treatment for metastatic breast cancer. Y-90 radioembolization can shrink liver tumors, relieve painful symptoms, boost the excellent of life and potentially extend survival. The therapy is not limited by tumor size, shape, place or quantity, and it can ease the severity of disease in patients who can not be treated effectively with other approaches. More

Mon 17 Feb 2014.Physicists reveal novel magnetoelectric effect that makes it possible to control magnetism with an electric field, ie "switching mechanism". The novel mechanism may provide a new route for using multiferroic materials for the application of RAM (random access memories) in computers and other devices, such as printers. The researchers studied a new predicted state of the multiferroic bismuth ferrite, a compound that can change its electrical polarization when under a magnetic field or magnetic properties when under an electric field. Because of these effects, bismuth ferrite interests researchers who want to design novel devices—based on magnetoelectric conversion. The "coupling mechanism" in bismuth ferrite between magnetic order and electrical polarization order is required for this phenomenon to be clearly understood. More

Sun 16 Feb 2014.Carbon nanotube fibers outperform copper in carrying electrical current. On a kg-per-kg basis, carbon nanotube-based fibers have greater capacity to carry electrical current than copper cables of the same mass, according to new research. While individual nanotubes are capable of transmitting nearly 1,000 times more current than copper, the same tubes coalesced into a fiber using other technologies fail long before reaching that capacity. But a series of recent tests showed the wet-spun carbon nanotube fiber still handily beat copper, carrying up to four times as much current as a copper wire of the same mass. More
