| 1 | Fabrication of on-chip probes for double-tip scanning tunneling microscopy显示文摘A reduction of the interprobe distance in multiprobe and double-tip scanning tunneling microscopy to the nanometer scale has been a longstanding and technically difficult challenge.Recent multiprobe systems have allowed for significant progress by achieving distances of~30 nm using two individually driven,traditional metal wire tips.For situations where simple alignment and fixed separation can be advantageous,we present the fabrication of on-chip double-tip devices that incorporate two mechanically fixed gold tips with a tip separation of only 35nm.We utilize the excellent mechanical,insulating and dielectric properties of high-quality SiN as a base material to realize easy-to-implement,lithographically defined and mechanically stable tips.With their large contact pads and adjustable footprint,these novel tips can be easily integrated with most existing commercial combined STM/AFM systems. | Maarten Leeuwenhoek Freek Groenewoud Kees van Oosten Tjerk Benschop Milan P.Allan Simon Groblacher | 2020 | Microsystems & Nanoengineering2020，6，1： | 1 |

| 3 | 多效唑对亚热带低寒带桃“Flordaprince”物候循环的影响显示文摘Allan,p,George,A.P,Nissen,R.J,Rasmussen,T.S.和Morley-Bunker,M.J,1993。多效吐对亚热带澳大利亚的低寒带桃“Flordaprince”物候循环的影响。园艺科学,53:73-84。将低寒带桃“Flordaprince”种植在亚热带澳大利亚,用多效吐处理两次以矮化树体,或使用氮处理来强化树体。疏花之后,调整并统一单株果实数,使每棵树的果实具有充分空间。多效唑能显著地抑制竞争性的春梢生长,引起果实提早成熟,并使产量增加,果实增大,品质提高。多效吐减少根的春季生长,而导致秋季根的大量生长。在乔化树中,果实生长的第二阶段稍长,使得种子和胚的生长推迟,胚中干物质较多。淀粉储藏量以根中为最大,其次是根干、枝和叶。在硬核期和果实成熟阶段,淀粉储藏量降到最低水平,但在枝梢伸长生长结束之后,又会升高,到落叶时,再次达到峰值。叶分析显示,整个季节中N、P和K的浓度降低,而Ca和Mg的浓度升高。多效唑处理树中,K的水平显著低于乔化树,而Ca、Mg水平显著高于乔化树。 | P.Allan A.P.George R.J.Nissen T.S.Rosmussen M.J.Morley-Bunker 孙建明 覃淑君 | 1997 | 绵阳经济技术高等专科学校学报1997，14，3： | 0 |
| 4 | Discrepancies in Simulated Ocean Net Surface Heat Fluxes over the North Atlantic显示文摘The change in ocean net surface heat flux plays an important role in the climate system.It is closely related to the ocean heat content change and ocean heat transport,particularly over the North Atlantic,where the ocean loses heat to the atmosphere,affecting the AMOC(Atlantic Meridional Overturning Circulation)variability and hence the global climate.However,the difference between simulated surface heat fluxes is still large due to poorly represented dynamical processes involving multiscale interactions in model simulations.In order to explain the discrepancy of the surface heat flux over the North Atlantic,datasets from nineteen AMIP6 and eight highresSST-present climate model simulations are analyzed and compared with the DEEPC(Diagnosing Earth's Energy Pathways in the Climate system)product.As an indirect check of the ocean surface heat flux,the oceanic heat transport inferred from the combination of the ocean surface heat flux,sea ice,and ocean heat content tendency is compared with the RAPID(Rapid Climate Change-Meridional Overturning Circulation and Heat flux array)observations at 26°N in the Atlantic.The AMIP6 simulations show lower inferred heat transport due to less heat loss to the atmosphere.The heat loss from the AMIP6 ensemble mean north of 26°N in the Atlantic is about10 W m–2 less than DEEPC,and the heat transport is about 0.30 PW(1 PW=1015 W)lower than RAPID and DEEPC.The model horizontal resolution effect on the discrepancy is also investigated.Results show that by increasing the resolution,both surface heat flux north of 26°N and heat transport at 26°N in the Atlantic can be improved. | Chunlei LIU Yazhu YANG Xiaoqing LIAO Ning CAO Jimmy LIU Niansen OU Richard P.ALLAN Liang JIN Ni CHEN Rong ZHENG | 2022 | Advances in Atmospheric Sciences2022，39，11： | 0 |
