"FINDING ORDER IN DISORDER"

"在无序的世界里寻找有序"

We are currently focused on:

1. The atomic structure of metallic glasses

2. The structure/properties tuning under high pressure

3. The disorder-order transition in metallic glasses

4. The polyamorphic transitions in metallic glasses

5. The structural heterogeneity of metallic glasses

6. The high pressure and high/low temperature properties of metallic glasses

7. The novel materials synthesis under high pressure and/or high temperature

8. Development of novel techniques dedicated to amorphous materials

Techniques we are mainly using:

1. Materials synthesis techniques:

Arc/induction melting, Suction/injection copper mold casting, Melt spinning.

2. Materials characterization techniques:

2.1 Synchrotron radiation techniques

     X-ray diffraction,

     Pair distribution function,

     X-ray absorption spectroscopy,

     X-ray resonant inelastic scattering spectroscopy,

     X-ray imaging

     X-ray small angle scattering

     X-ray photo correlation spectroscopy

     X-ray emission spectroscopy

2.2 Microscopic structure characterization

     Scanning electron microscopy (SEM)

     High resolution electron transmission microscopy (HRTEM)

     Atomic force microscopy (AFM)

2.3 Laser Raman spectroscopy

2.4 Electrical and magnetic properties measurement using PPMS

2.5 Mechanical properties testing (tension, compression, micro/nano-indentation),

2.6 Ultrasonic measurement,

2.7 Density measurement,

2.8 Differential scanning calorimetry (DSC)

2.9 Simulation (Reverse Monte Carlo, Molecule Dynamics, etc.)

3. Extreme conditions techniques:

3.1 High pressure (Diamond anvil cell (DAC), Multi-anvil Press, Paris-Edinburgh cell, Dynamic compression in DAC, Four-probe resistance measurement in DAC)

3.2 Low temperature (Cryostat)

3.3 High temperature (Laser heating, Resistive heating)
