	The teams of Professor Lu Junling, Professor Yang Jinlong, and Professor Wei Shiqiang of the University of Science and Technology of China cooperated with atomic layer deposition to accurately construct the single-site Fe1(OH)x species on the surface of Pt metal nanoparticles supported by SiO2 for the first time, and then formed a novel Fe1(OH)x-Pt single-site interface catalyst structure. The result was published...

	The microstructure of the active layer of the heterojunction organic solar cells has an important effect on the performance of the device. To date, a variety of optimization methods can control the microstructure of the active layer, solvent additive method is simple convenient and can greatly enhance photovoltaic performance which is a significant morphological control method. However, the mechanism of action of ...

	For the development of new optoelectronic materials, alternating conjugated electron donor-acceptor (D-A) polymers have been intensively studied in recent years. Normally, the molecular design strategy is to devise new electron-rich and -deficient frameworks. Zhang et al. (Institute of Chemistry, Chinese Academy of Sciences) have recently disclosed a new bis-amide acceptor (BPD), and successfully utilized BPD to s...

	Zhang et al. (Institute of Chemistry, Chinese Academy of Sciences) mainly focused on the “structure-property” relationships of conjugated polymers. Recently, they introduced three novel DPP-based polymers through fine-tuning the structures of conjugated backbone. The results of calculations and UV-vis spectra demonstrated that the structures of polymers have remarkable influences on energy levels, molecular conf...

	Heme iron and non-heme iron are two forms of iron resources in diet,and approximately 70％of the total iron exists in the form of heme iron. Moreover, supplementation of heme iron is the first choice to treat iron deficiency anemia. Early in 1955, heme-derived iron was first reported to be absorbed by enterocytes. However, it is still unknown clearly the mechanism of heme iron absorption, which is mainly due to th...

	In natural photosynthesis, water oxidation reaction is catalyzed by μ-oxido-Mn4Ca cluster in photosystem II (PSII). It has been reported that the active site for natural PSII is CaMn4O5 cluster with three Mn and one Ca forming a distorted CaMn3O4 cubane and the fourth Mn ion bonding to this cubane by additional μ-oxido ligand. In order to reveal the mechanism of oxygen formation, synthesis of CaMn4O5 cluster mim...
