Delicate architecture of active material enables improving the performacne of lithium ion batteries. Environmental‐friendly Fe2O3 anode has high theoretical specific capacity (1007 mAh g−1) in lithium ion batteries, but suffers from structural collapsing and poor electronic conductivity. Her...
Label‐free super‐resolution effect of nonlinear reverse saturation absorption (NRSA) thin films was investigated through difference method, where a sub‐diffraction‐limit spot signal was constructed by intensity subtraction of two spots obtained under different laser intensities. By using ann...
D.W. DE KORT,
H. DE JONG,
There exists a strong motivation to increase the spatial resolution of magnetic resonance imaging (MRI) acquisitions so that MRI can be used as a microscopy technique in the study of porous materials. This work introduces a method for identifying novel data sampling patterns to achieve under...
The interactions between plant roots and soil are an area of active research, particularly in terms of water and nutrient uptake. Because noninvasive, in vivo studies are required, tomographic imaging appears an obvious method to use, but no one imaging modality is well suited to capture th...
This letter considers the “Portrait of a Mathematician” attributed to Mary Beale in the 1680s as a likely candidate for a portrait of Robert Hooke made during his lifetime. It closely matches the physical descriptions of Hooke made by his biographers who knew him, Richard Waller (d. 1715) a...
