To investigate the effect of ligand on the TFT properties, we focused on the In2O3 NCs films cured at 150 °C. Both the ligand molecules OA and BET were conserved on the NCs surface in the TFT devices at a curing temperature of 150 °C. The TGA curves confirmed no weight loss at 150 °C (Figure. 4). Moreover, the FTIR spectrum of the thin films cured at 150 °C also supported the existence of the ligand molecules OA and BET with high intensity peaks of the alkyl group Csp3-H and carboxylate group COO-

Dark Matter was first proposed by Fritz Zwicky in the 1930’s when he observed the motions of galaxies and he noticed that the amount of visible objects could not account for the observations he made. There had to be some “invisible” mass holding these galaxies together. It is known that 25% of our universe is made up dark matter versus 4% of the visible matter we know and interact with every day. The leading candidates for dark matter are MACHOs and WIMPS. Gravitational lensing is one of the ways

Introduction It is difficult to determine the birth of nuclear medicine due to the many contributions made my scientists of carious fields. However, most notably, during bla blah Understanding the uses, benefits and side effect of nuclear medicine is crucial due to its significant and ongoing contribution to the medical field. Throughout this paper focus will be placed on how radioactivity has benefited the detection, control and at times, complete elimination of cancer. Background Nuclear medicine
