The system includes "concept functions", which are special functions which act on and deliver conc...

DNA origami is an interdisciplinary area where DNA can be used as a building block for making useful stuff at nanoscale. This work presents an open source software DNA pen (based on the recent work of Peng Yin and his group) which can be used (using free hand and digital molecular canvas) to draw an object at nanoscale. Software generates error free DNA sequences which can be used in the wet la...

For the past 20 years, THz pulsed time-domain imaging has been used to study internal structure of various paintings. The main advantage this technique is that it can nondestructively provide depth profiles, as well conditions preparation and support layers, which are important in conservation planning. We have applied artworks with linings, additional layers fabric or paper adhered back an ori...
