| 1 | Multiscale computational understanding and growth of 2D materials:a review显示文摘The successful discovery and isolation of graphene in 2004,and the subsequent synthesis of layered semiconductors and heterostructures beyond graphene have led to the exploding field of two-dimensional(2D)materials that explore their growth,new atomic-scale physics,and potential device applications.This review aims to provide an overview of theoretical,computational,and machine learning methods and tools at multiple length and time scales,and discuss how they can be utilized to assist/guide the design and synthesis of 2D materials beyond graphene. | Kasra Momeni Yanzhou Ji Yuanxi Wang Shiddartha Paul Sara Neshani Dundar E.Yilmaz Yun Kyung Shin Difan Zhang Jin-Wu Jiang Harold S.Park Susan Sinnott Adri van Duin Vincent Crespi Long-Qing Chen | 2020 | npj Computational Materials2020，，1： | 4 |
| 2 | Bioactivity and constituents of several common seaweeds显示文摘Bioactivity and constituents of 8 common seaweeds from Dalian intertidal zone of northern Yellow Sea were investigated. In the anti-methicillin-resistant Staphylococcus aureus (MRSA) test, Symphyocladia latiuscula and Enteromorpha intestinalis showed obvious activities with MICs much lower than 1.0 mg·mL-1 . In the DNA damage repair test (DDRT), Chondrus ocellatu showed selective inhibitory activity against the DNA repair-defective E. coli strain vs. the wild-type E. coli strain; while Sym. latiuscula, Enteromorpha intestinalis and Sar. kjellmanianum showed significant anti-E. coli activity with MICs of 64-128 g·mL-1 . In the anti-Pyricularia oryzae test, Sym. latiuscula and Rh. confervoides strongly inhibited the germination of the spores of P. oryzae on agar plate. In the brine shrimp larvicidal test, Sym. latiuscula, Rh. confervoides and Sar. kjellmanianum exhibited potent toxicity against brine shrimp larvae, with LC50 much lower than 1 mg·mL-1 . The HPTLC analysis revealed their diversified secondary metabolites. The HPLC-DAD-MS analysis of the strongest species Sym. latiuscula and database searching showed that it can produce quite diversified metabolites, including halogenated ones, some of which may be new natural products. The results demonstrated the potentials of these seaweeds in the development of new antibiotics, antitumor drugs, agricultural fungicides and pesticides. | ZHANG Yi HAN JinYuan MU Jun FENG Yan GU XiaoJie JI YuanXi | 2013 | Chinese Science Bulletin2013，58，19： | 2 |
