Trapping and manipulation of microscale and nanoscale particles is demonstrated using the sole action of hydrodynamic forces. We developed an automated particle trap based on a stagnation point flow generated in a microfluidic device. The h...
Piezoelectric activity of relaxor-PbTiO(3) based single crystals and polycrystalline ceramics at cryogenic temperatures: Intrinsic and extrinsic contributions [0.03%]
弛豫型PbTiO₃铁电单晶和多晶陶瓷的低温压电性：内在与外在贡献

A strategy for rapid and facile detection of melamine in food and other substances is described. Unmodified gold nanoparticles enable a colorimetric signal output that is amplified through integration by precipitation formation via a chemic...
Water film thickness-dependent conformation and diffusion of single-strand DNA on poly(ethylene glycol)-silane surface [0.03%]
单链DNA在聚乙二醇硅烷表面水膜上的构象和扩散行为受水膜厚度调控
