Supramolecular self-assembly at the solid-solid interface enables the deposition and monolayer formation of insoluble organic semiconductors under ambient conditions. The underlying process, termed as the organic solid-solid wetting deposition (OSWD), generates two-dimensional adsorbates directly from dispersed three-dimensional organic crystals. This

Despite the rising health and safety concerns of e-cigarettes, a universal e-cigarette testing method is still in its early developmental stage. The aim of this study was to develop an e-liquid Reference Material that can be used to improve accuracy

Although high-frequency ultrasound imaging is gaining attention in various applications, hardly any ultrasound contrast agents (UCAs) dedicated to such frequencies (>15 MHz) are available for contrast-enhanced ultrasound (CEUS) imaging. Moreover, the composition of the limited commercially available UCAs for high-frequency

Human and mouse oocytes were cryopreserved by a slow freeze, rapid thaw method, using propanediol (PROH) as the cryoprotectant. A simulated cryopreservation was also included in the study to detect the level of damage attributable to the PROH alone. Comparison

Eighty-five human embryos fertilized in vitro were frozen and thawed with 1,2 propanediol as a cryoprotective agent. The effects of viability of in vitro culture duration, stage, and morphologic appearance of embryos were examined after thawing. Survival was higher for
