Automatic identification of artistic pigments by Raman spectroscopy using fuzzy logic and principal component analysis [PDF]
, 2006 This work offers an automatic identification system of Raman spectra of artistic pigments. The proposed methodology is based on a fuzzy logic system, and uses principal component analysis to reduce redundancies in data and the correlation operator as an ...

Identification of Novel Pigmentation Modulators by Chemical Genetic Screening [PDF]
Journal of Investigative Dermatology, 2007 There is a continual need for compounds that effectively modulate melanin synthesis. To identify novel pigmentation modulators and their cellular targets, chemical genetic screenings were performed with triazine-based combinatorial libraries that include various linkers as intrinsic components of the small molecules in the library.

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics
Advanced Materials, EarlyView.“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.
