Abstract
Radiation causes damage to the human body, the environment, and electronic equipment. Shielding against neutron and gamma rays is particularly difficult because of their strong ability to penetrate materials. Conventional gamma ray shields are typically made of materials containing Pb. However, they pose problems in that Pb is a heavy..... More

Abstract
Si/SiO_x composite anodes were prepared using a facile solution reaction-based method. Their initial capacity was significantly improved to 1.3 times that of SiO_x by incorporating 3 wt% silicon nanoparticles into the SiO_x. The capacity retention of the Si/SiO_x anodes after 50 charge-discharge cycles was significantly enhanced, to 99%, compared with..... More
