To improve the low compactness and limited size of powder metallurgy (P/M) aluminum alloy materials, cold rolling deformation on P/M was carried out in this work. And microstructure mechanical properties during were investigated from multi-dimensional multi-scale perspectives. The results indicate that gradually evolved original equiaxial structure to fiber after rolling. Also, grain decreased with an increase cumulative reductions. When reduction increased 0 80%, relative density tensile...
Detection limit of sodium fluorescein in plant cells can reach 0.14 μg cm<sup>−3</sup> based on LRET from UCNPs to SF.
This paper proposed a novel low-pressure sintering process contraposing to characteristics of pre-alloyed aluminum powders and analyzed its feasibility. The low pressure was set 0.1 MPa in this study. Meanwhile, 0 10 were as control group. With gas-atomized 2024 raw material, the microstructure tensile properties specimens sintered under three orders magnitude (0 MPa, MPa) at two representative temperatures (525 °C 575 °C) compared. results showed that it difficult for pressureless densify...
Upconversion NaLuF<sub>4</sub> nanoprobes with intense visible fluorescence and good biocompatibility have been successfully constructed for assessing the irritation of trace organic molecules in jellyfish cells based on LRET process.
Upconversion nanoparticles (UCNPs) based on NaYF 4 nanocrystals with strong upconversion luminescence are synthesized by the solvothermal method. The emission color of these can be easily modulated doping. These employed as fluorescence donors to pump fluorescent organic molecules. For example, efficient resonant energy transfer (LRET) achieved controlling distance between :Yb 3+ /Er UCNPs and Rhodamine B (RB). emit green light at wavelength ~540 nm while RB efficiently absorb red 610 nm....
Nanotechnology is receiving increasing attention due to its fantastic advantages and potential applications in nanofood nanomedicine. However, the safety of touching manufactured nanoparticles still uncertain for human beings. Here, we track inorganic digestive system mouse through upconversion fluorescence X-ray imaging, try demonstrate whether or not will penetrate enter blood system. Lanthanide-doped nanoparticles, which can convert infrared light visible are simultaneously sensitive...
Abstract In order to solve the problem of edge cracking as‐sintered 2024 aluminium alloy during cold rolling, initiation mechanisms were studied. The results indicate that “herringbone” crack parallel rolling direction and “zigzag” perpendicular easily formed rolling. former mainly occurred early stage was related poor plasticity stress state at end rolled plate, whereas latter appeared in a sample with reduction more than 60%, because grains subjected three‐direction shear stress, which...
