Different Temperatures

Positron annihilation lifetime measurements have been performed on three molecular systems: propylene carbonate, salol and m-toluidine at the temperature range from 20 K up to 300 K. The time dependences of the orthopositronium lifetime and intensity have been observed at the temperature range between a solid state and the liquid state. These changes can be explained as transitions from the amorphous phase to one or two crystalline phases. The crystallization process from cooled liquid was observed in all three cases at different temperatures on the time scale up to 60 hours.

Solid-state nanopores have been developed as a prominent tool for single molecule analysis in versatile applications. Although controlled dielectric breakdown (CDB) is the most accessible method for a single nanopore fabrication, it is still necessary to improve the fabrication efficiency and avoid the generation of multiple nanopores. In this work, we treated the SiNx membranes in the air–plasma before the CDB process, which shortened the time-to-pore-formation by orders of magnitude. λ-DNA translocation experiments validated the functionality of the pore and substantiated the presence of only a single pore on the membrane. Our fabricated pore could also be successfully used to detect short single-stranded DNA (ssDNA) fragments. Using to ionic current signals, ssDNA fragments with different lengths could be clearly distinguished. These results will provide a valuable reference for the nanopore fabrication and DNA analysis.
