The article presents information on a six-week project aimed at conserving and digitizing the rolled leaf manuscripts at the Asa Archives in Kathmandu, Nepal. The project was carried out by the Paper Conservators Asia Unlimited. The Asa Archives has more than 6,700 manuscripts on different topics. It has digitized almost all its collection of manuscripts except rolled palm leaf manuscripts. These rolled palm leaf manuscripts were not digitized for the fear of damaging them while opening. The Asa Archives has around 1000 catalogued and 300 uncatalogued rolled palm leaf manuscripts.

AbstractMolecular tiling has been developed as a novel technique for controlled molecular arrangements in two-dimensional plane. The π-A isotherm of a cyclophane derivative with eight alkyl chains has a limiting area apparently smaller than the cyclophane core, indicating that the cyclophane core was deformed at high pressures. In contrast, the equimolar-mixed monolayer of the cyclophane derivative and a guanidinium amphiphile on an aqueous naphthalene guest showed an isotherm with a limiting area comparable to the cyclophane core. A drastic increase in surface fluorescence due to the guest insertion was also observed. These results strongly indicate that the cyclophane derivative formed a rigid complex with the guanidinium amphiphile and aqueous naphthalene derivative. The formed complex can be a good candidate for a tiling unit.
