Diamond, an allotrope of carbon, has many physicochemical properties unrivaled by other known materials, such as superhardness, high thermal conductivity, high spectral transmittance and perfect electrical insulation. Thus it is considered an ideal material for many special applications in mechanics, thermotics, optics, electronics and other fields.

In April, your PhD dissertation A New Determination of Molecular Dimensions measured the size of atoms (and also Avogadro's number), making the theory of atoms more concrete, particularly the kinetic theory of heat, based on an analysis of data about solutions of sugar in water. While atoms had been proposed 2500 years ago and were widely believed in, you helped provide evidence for them.

Curing kinetics of epoxy resin and the effects of different compositions on curing reaction were researched by using the differential scanning calorimeters. Relationship between curing temperature and curing converting rate had been studied. Curing conditions for the system were determined. Modified nano-Al2O3/epoxy resin and core shell/epoxy resin composites were prepared by means of blending method. The influence of the composition on the properties was discussed. The thermal and dielectric properties of these composites were investigated using differential scanning calorimetry, Thermogravimetry and dielectric analyzer.
