Positronium is the simplest bound state, built of an electron and a positron. Studies of
positronium in vacuum and its decays in medium tell us about quantum electrodynamics …

In this review article, we present arguments demonstrating that the advent of high sensitivity
total-body PET systems and the invention of the method of positronium imaging, open …

The number of biomedical applications of hydrogels is increasing rapidly on account of their
unique physical, structural, and mechanical properties. The utility of hydrogels as drug …

Sphingolipids contain in their polar heads chemical groups allowing them to establish a
complex network of H-bonds (through different single bondOH and single bondNHsingle …

The effects of increasing amounts of palmitoylceramide (pCer) on human red blood cell lipid
membranes have been studied using atomic force microscopy of supported lipid bilayers, in …

Lipid model membranes are important tools in the study of biophysical processes such as
lipid self-assembly and lipid–lipid interactions in cell membranes. The use of model systems …

Free volume voids in lipid bilayers can be measured by positron annihilation lifetime
spectroscopy (PALS). This technique has been applied, together with differential scanning …

The physics and mechanics governing the shape memory effect in shape memory polymers
is not fully understood at the nanoscale. A very recent publication highligths a possible link …

Profiles of various membrane characteristics are traditionally calculated from the middle
plane of the membrane towards the surface. In this approach, atomic positions near the …

Long-chain alkylresorcinols (ARs) are commonly found in plant and bacteria cells, and they
exhibit a wide variety of biological effects, including antifungal, antitumor, and antiphrastic …
