1. 1. A short story of the long telomere : evidence in aging epidemiology

   Författare :Yiqiang Zhan; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Telomeres are the sequences of nucleotides at the end of chromosomes. Each time a cell divides, telomeres become shorter. The length of telomeres can be replenished by an enzyme, telomerase. Telomere shortening is hypothesized as the biological origin of aging. LÄS MER

3. 2. Image dipoles and polarons in organic semiconductors

   Författare :Yongzhen Chen; Mats Fahlman; Xianjie Liu; Yiqiang Zhan; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; Interface dipole; Polaron; Conjugated polymer; Photoelectron spectroscopy; N-type doping; Electron transport material;

   Sammanfattning : The rapid development of organic electronics depends on the synthesis of new π-conjugated molecules/polymers and the exploration of fundamental physics. However, most of the efforts have been concentrated on the former, leading to a lack of thorough understanding of many important concepts, which will become the ultimate limiting factor for overall performance and applications.
