Nanoscale chemical mapping of laser-solubilized silk
Meguya Ryu, Hanae Kobayashi, Armandas Balcytis +8
A water soluble amorphous form of silk was made by ultra-short laser pulse irradiation and detected by nanoscale IR mapping. An optical absorption-induced nanoscale surface expansi…

Orientational Mapping Augmented Sub-Wavelength Hyper-Spectral Imaging of Silk
Meguya Ryu, Armandas Balcytis, Xuewen Wang +6
Molecular alignment underpins optical, mechanical, and thermal properties of materials, however, its direct measurement from volumes with micrometer dimensions is not accessible, e…

Percolation threshold gold films on columnar coatings: characterisation for SERS applications
Armandas Balcytis, Tomas Tolenis, Xuewen Wang +4
Percolation of gold films of ~15 nm thickness was controlled to achieve the largest openings during Au deposition. Gold was evaporated on 300-nm-thick films of nanostructured porou…
