Article Synopsis
- The study explores the effects of turbulent convective flows in a laboratory setting, focusing on how periodic temperature changes in a Rayleigh-Bénard cell mimic natural processes driven by solar heating.
- Researchers analyze the unique characteristics of turbulent buoyancy-driven flows using cryogenic helium gas and temperature sensors to gain insights into heat flow dynamics.
- The findings aim to enhance understanding of energy budgets in ocean currents and weather patterns on Earth, potentially informing models for similar natural processes on other planets.
We have designed a supporting system to fix a sample holder of a scanning tunneling microscope in an UHV chamber at room temperature. The microscope will operate down to a temperature of 20 K. Low thermal conductance, high mechanical stiffness, and small dimensions are the main features of the supporting system.

At gaps smaller than one-third of the peak wavelength λ(m) given by Wien's displacement law, the near-field effect was observed. In comparison with blackbody radiation, hundred times higher values of heat flux were achieved at d≈1 μm.
