Nano-scale analysis of titanium dioxide fingerprint-development powders [PDF]

, 2008
Titanium dioxide based powders are regularly used in the development of latent fingerprints on dark surfaces. For analysis of prints on adhesive tapes, the titanium dioxide is suspended in a surfactant and used in the form of a small particle reagent ...

SCALe‐invariant Integral Surfaces [PDF]

Computer Graphics Forum, 2013
AbstractExtraction of skeletons from solid shapes has attracted quite a lot of attention, but less attention was paid so far to the reverse operation: generating smooth surfaces from skeletons and local radius information. Convolution surfaces, i.e. implicit surfaces generated by integrating a smoothing kernel along a skeleton, were developed to do so.

Surface oxygen vacancy trigger chlorite activation with BiOI for sulfamethoxazole degradation

Journal of Industrial Safety
A UV-induced modification method was employed to introduce photoexcited oxygen vacancies (OV-BiOI) into BiOI, creating a multiphase catalyst that effectively catalyzes chlorite to yield chlorine dioxide (ClO2), the primary reactive oxygen species (ROS ...
