Recent experiments and simulations suggest that photosynthetic systems and the surrounding protein environments operate optimally to achieve efficient and robust energy transfer.To clarify the optimal transfer conditions in photosynthetic systems and explore the optimal design principles for artificial energy transfer devices,we present three theoretical studies:1) Calculations of model exciton systems and realistic photosynthetic systems suggest that dissipation can help optimize energy transfer efficiency and that spatial correlations in environmental fluctuations are crucial for quantum coherence in quantum transport processes.

如今,非挥发性快闪存储器已广泛应用于各种便携式电子产品,增加存储容量和降低生产成本成为了快闪存储器发展的目标.然而当存储单元的尺寸进一步减小,接近物理极限时,通过减小单元尺寸来增加存储容量的方法就不可行了.
采用溶胶-凝胶水热法制备纳米二氧化钛及其稀土铒离子掺杂改性的产物,之所以要稀土铒离子掺杂对二氧化钛改性,是因为二氧化钛的带系为3.2eV,只能被波长较短的紫外线激发,而紫外线在太阳光中仅占3%-4%,太阳能利用率较低.
