In this study, the use of a 3D printer for sample holder fabrication and polymer sample preparation for positron analysis was explored. Custom printed 3D holders may be rapidly made and modified for a variety of thin-film, crystalline, or other diver

We have studied the interaction of the positron with chiral left-or right-handed quartz crystals. In Doppler-broadening experiments, using a mono-energetic positron beam there is a differential depth profile for positrons implanted in LH or RH z-cut

Positron annihilation spectroscopy measures free volume in membranes at the sub-nanometer scale (0.1–1 nm). In this study, we used positron annihilation age–momentum correlation (AMOC) spectroscopy coupled to a variable mono-energy slow positron

Positron annihilation spectroscopy (PAS) is a novel method that provides molecular-level information about complex macromolecular structure in a manner different from, but complementary to, conventional physical and chemical methodology. This paper p

The development of the microstructure of carbon molecular sieve membranes (CMSMs) was examined using a variable monoenergy slow positron beam (VMSPB). To vary the structure of the CMSMs fabricated by pyrolyzing a Kapton precursor, different pyrolysis

We have studied alcohol- and water-induced swelling and sorption of PBI and PBI/ZIF-8 nano-composite membranes and characterized both dry and wet membranes by positron annihilation lifetime spectroscopy (PALS). The degrees of membrane swelling after
