Sample holder setup showing plasma cleaning of holey carbon grids for TEM imaging, using Henniker Plasma system and JEOL-compatible adapter.

TEM Sample Plasma Cleaning

Below, we examine the effectiveness of plasma cleaning for microscopy using a Henniker Plasma Cleaner for holey carbon grid preparation in TEM and SEM applications. This work, summarised here, was completed with our HPT-100 Plasma Cleaning System and a JEOL-compatible TEM sample holder adapter.

Time-lapse and temperature-dependent images showing spiral fluid flow patterns inside a turbine or impeller system, with red dashed lines indicating changes in flow front position at various time intervals and temperatures ranging from 155°C to 295°C.

Recently, thin-film boiling, via the Leidenfrost effect, has been demonstrated as a promising concept for converting thermal energy to mechanical motion. In this 2019 published paper, the authors address two key challenges users face when working with Leidenfrost heat engine levitating rotors and their sustained rotation. Their aim, “to provide new opportunities for novel approaches for heat to motion conversion in extreme environments”.
