      Lin, Xiao; Xu, Yang; Hakro, Ayaz Ali; Hasan, Tawfique; Hao, Ran; Zhang, Baile; Chen, Hongsheng (2013)
      The fascinating optical properties of graphene are usually concluded in theory under the assumption that graphene is freestanding. However, in experimentally realizable devices, graphene is usually supported by a substrate, ...
    • Ab initio simulation of electronic and mechanical properties of aluminium for fatigue early feature investigation 

      Zhang, Shuai; Tan, Cher Ming; Cheng, Shuguang; Deng, Tianqi; He, Feifei; Su, Haibin (2014)
      Fatigue crack initiation and propagation are the central issues for understanding fatigue behaviours, and early detection of fatigue will be useful in industry before cartographic events occur. It has been found that surface ...

      In this paper we use variable reaction coordinate variational transition state theory (VRC-TST) to calculate the reaction rate constants for the two reactions, R1: (OH)3SiOCH2 + CH3 ⇌ (OH)3SiOC2H5, and R2: CH2OH + CH3 ⇌ C2H5OH. ...
    • Ab-initio study of donor-acceptor codoping for n-type CuO 

      Peng, Yuan; Zheng, Jianwei; Wu, Ping; Wang, Junling (2014)
      Single n-type dopant in CuO has either a deep donor level or limited solubility, inefficient in generating free electrons. We have performed ab-initio study of the donor-acceptor codoping to obtain n-type CuO. Our results ...
    • ABC transporter-dependent brain uptake of the 5-HT1B receptor radioligand [11C]AZ10419369 : a comparative PET study in mouse, rat, and guinea pig 

      Tóth, Miklós; Häggkvist, Jenny; Varrone, Andrea; Finnema, Sjoerd J; Doorduin, Janine; Tokunaga, Masaki; Higuchi, Makoto; Gulyás, Balázs; Halldin, Christer (2014)
      Background We have explored the possibility that the serotonin 1B receptor radioligand [11C]AZ10419369 is a substrate for adenosine triphosphate (ATP)-binding cassette (ABC) transporters, such as P-glycoprotein (P-gp), ...
    • ABC transporters, neural stem cells and neurogenesis : a different perspective 

      Lin, Tingting; Omedul Islam; Heese, Klaus (2006)
      Stem cells intrigue. They have the ability to divide exponentially, recreate the stem cell compartment, as well as create differentiated cells to generate tissues. Therefore, they should be natural candidates to provide a ...
    • Abc3-mediated efflux of an endogenous digoxin-like steroidal glycoside by magnaporthe oryzae is necessary for host invasion during blast disease 

      Patkar, Rajesh N.; Xue, Yang Kui.; Shui, Guanghou.; Wenk, Markus R.; Naqvi, Naweed Issak. (2012)
      Magnaporthe oryzae, which causes the devastating rice-blast disease, invades its host plants via a specialized infection structure called the appressorium. Previously, we showed that the ATP-Binding Cassette 3 transporter ...
    • The abduction of Libya’s prime minister : militias run rampant 

      Ahmed Salah Hashim (2013)
      On 10 October, 2013, Libyan Prime Minister Ali Zeidan was briefly abducted by one of Libya’s numerous militia groups but was released unharmed hours later. His abduction may have more to do with the peculiar dynamics of ...
    • Abdullah Azzam : would he have endorsed 9/11? 

      Muhammad Haniff Hassan; Mohamed Redzuan Salleh (2009)
      According to Al Qaeda, attacking Westerners, such as in the case of September 11, is theologically permissible. However, a study shows this view being contradicted by primary sources that belong to Abdullah Azzam, the ...
