    • Ion beam irradiation-induced amorphization of nano-sized KxLnyTa2O7-v tantalate pyrochlore 

      Lu, Fengyuan; Shen, Yiqiang; Dong, Zhili; Wang, Gongkai; Zhang, Fuxiang; Ewing, Rodney C.; Lian, Jie (2014)
      Nano-sized (~10–15 nm) tantalate pyrochlores KxLnyTa2O7-v (Ln = Gd, Y, and Lu) were irradiated with 1 MeV Kr2+ beams at different temperatures and their radiation response behaviors were studied by in situ transmission ...
    • Ion implantation in silicon to facilitate testing of photonic circuits 

      Reed, Graham T.; Milosevic, Milan M.; Chen, Xia; Cao, Wei; Littlejohns, Callum George; Wang, Hong; Khokhar, Ali Z.; Thomson, David J. (2017)
      In recent years, we have presented results on the development of erasable gratings in silicon to facilitate wafer scale testing of photonics circuits via ion implantation of germanium. Similar technology can be employed ...
    • Ion-dependent electroluminescence from trivalent rare-earth doped n-ZnO/p-Si heterostructured light-emitting diodes 

      Iwan, S.; Zhao, J. L.; Tan, S. T.; Bambang, S.; Hikam, M.; Fan, H. M.; Sun, Xiao Wei (2014)
      We have demonstrated rare earths (REs) doped ZnO-based heterojunction light-emitting diodes (LEDs) on p-Si substrates by ultrasonic spray pyrolisis (USP). Room-temperature electroluminescence was clearly observed from ...
    • Ion-induced synthesis of uniform single-crystalline sulphide-based quaternary-alloy hexagonal nanorings for highly efficient photocatalytic hydrogen evolution 

      Hu, Peng; Pramana, Stevin Snellius; Cao, Shao-Wen; Ngaw, Chee Keong; Lin, Jingdong; Loo, Say Chye Joachim; Tan, Timothy Thatt Yang (2013)
      Uniform single-crystalline quaternary sulphide nanoring photocatalysts are synthesized via the copper-ion-induced Kirkendall effect and is followed by a cation exchange reaction. The obtained Cu2+-doped ZnIn2S4 nanorings ...
    • Ionic Origin of Electro-osmotic Flow Hysteresis 

      Lim, Chun Yee; Lim, An Eng; Lam, Yee Cheong (2016)
      Electro-osmotic flow, the driving of fluid at nano- or micro- scales with electric field, has found numerous applications, ranging from pumping to chemical and biomedical analyses in micro-devices. Electro-osmotic flow ...
    • IONS and the Indian Ocean: reviving a listless initiative 

      P. K. Ghosh (2014)
      Despite an enthusiastic start in 2008, the only pan Indian Ocean Region maritime security initiative, IONS, had fallen into strategic inertia, threatened by creeping irrelevance. Will the growing interest of China and other ...
    • IP watermarking using incremental technology mapping at logic synthesis level 

      Cui, Aijiao; Chang, Chip Hong; Tahar, Sofiène (2008)
      This paper proposes an adaptive watermarking technique by modulating some closed cones in an originally optimized logic network (master design) for technology mapping. The headroom of each disjoint closed cone is evaluated ...
    • IP-enabled C/C++ based high level synthesis : a step towards better designer productivity and design performance 

      Sinha, Sharad; Srikanthan, Thambipillai (2014)
      Intellectual property (IP) core based design is an emerging design methodology to deal with increasing chip design complexity. C/C++ based high level synthesis (HLS) is also gaining traction as a design methodology to deal ...
    • IP-enabled wireless sensor network 

      Gao, Deyun; Foh, Chuan Heng; Yang, Oliver W. W.; Sun, Xusheng; Lai, Chin-Feng (2012)
      In wireless sensor networks (WSNs), the use of the IP technology has always been considered inadequate due to its high overhead in processing and memory usage. However, the use of IP technology in WSNs can provide basis ...
    • Iran : challenges for US intelligence and policy 

      Jervis, Robert. (2013)
      Dealing with Iran and its nuclear programmes challenges the skill and ingenuity of American intelligence and policymakers. Crafting a successful policy requires understanding Iran, but such judgements are politically as ...
    • Iran : how intelligence and policy intersect 

      Robert Jervis (2013)
      No issue is receiving more attention in American intelligence and policy-making circles than Iran and its nuclear program. Unfortunately, it is rare for intelligence in areas like this to be fully accurate and definitive, ...
    • The Iran nuclear deal : containment or appeasement? 

      Tan, Eugene E. G. (2015)
      The Lausanne agreement on Iran’s nuclear programme was hailed by all P5+1 parties as a positive step toward preventing Iran from developing its nuclear arsenal. While critics are doubtful, it could reduce the likelihood ...
    • Iran nuclear deal : expect limited US-Iran détente 

      Sumitha Narayanan Kutty (2015)
      The nuclear negotiations between Iran and the P5+1 countries have witnessed unprecedented diplomatic engagement between the United States and Iran. Contrary to expectations, a final nuclear deal will not achieve a ...
    • The Iran nuclear deal : rewriting the middle east map 

      James M. Dorsey (2013)
      The agreement to resolve the Iranian nuclear programme could rewrite the political map of the Middle East and North Africa, as well as strengthen the US pivot to Asia. It could also reintegrate Iran into the international ...
    • Iran Nuclear Deal: A Blessing in Disguise for ISIS? 

      Shahzeb Ali Rathore (2015)
      The Iran nuclear deal pursued by the United States will be capitalised by ISIS within the aggrieved Sunnis as just another alliance between the West and the Shiites, thus lending more support for the ISIS push for a ...
    • Iran's infrastructure projects: India, China competing? 

      Kutty, Sumitha (2016)
      With international sanctions lifted against Iran last week, New Delhi would be wise to step up its efforts to secure the contract for developing the Chabahar port in Iran. Time is no longer on its side as the writer observed ...
