1. Modeling of Electron Cooling : Theory, Data and Applications
Abstract : The Vlasov technique is used to model the electron cooling force. Limitations of the applicability of the method is obtained by considering the perturbations of the electron plasma. READ MORE

2. Structure determination of beam sensitive crystals by rotation electron diffraction : the impact of sample cooling
Abstract : Electron crystallography is complementary to X-ray crystallography. Single crystal X-ray diffraction requires the size of a crystal to be larger than about 5 × 5 × 5 μm3 while a TEM allows a million times smaller crystals being studied. This advantage of electron crystallography has been used to solve new structures of small crystals. READ MORE

3. Ultrasensitive Cold-Electron Bolometer
Abstract : The Cold-Electron Bolometer (CEB) is an ultrasensitive device designed for the detection of cosmic microwave background radiation. The key to its sensitivity is the electron cooling of the absorber by the superconductor-insulator-normal metal (SIN) tunnel junction. READ MORE

4. 3D Electron Diffraction : Application and Development towards High-quality Structure Determination
Abstract : Electron crystallography has been proven to be effective for structure determination of nano- and micron-sized crystals. In the past few years, 3D electron diffraction (3DED) techniques were used for the structure solution of various types of complex structures such as zeolites, metal-organic frameworks (MOF) and pharmaceutical compounds.

5. Cold-Electron Bolometer with Superconductor-Insulator-Normal Metal Tunnel Junctions
Abstract : The Cold-Electron Bolometer (CEB) is an ultrasensitive device designed for the detection of radiation in the terahertz region of the electromagnetic spectrum. The key to its sensitivity is the electron cooling of the absorber by the superconductor-insulator-normal metal (SIN) tunnel junction. READ MORE
