1.搭建以金刚石对顶砧为主体的综合极端超高压环境。验证了理论预测的超高压下镧氢体系的近室温超导特性，超导转变温度达到了260K。在国际上首次解决了超高压下的磁测量问题-实现了金刚石对顶砧中NV中心自旋量子态的相干调控，利用这种技术首次发现了永磁材料Nd₂Fe₁₄B的常温高压下的铁磁淬灭行为。利用金刚石对顶砧并辅以高压中子、拉曼等手段发现多种高压磁有序及超导的竞争与协作行为，发现了多种新型高压超导体。发现了多种无机及有机材料在高压下的发光行为，实现了不发光-到发光的0-1的转变，为新的聚集发光及半导体发光理论做出了重要贡献。

2. 在高温高压条件下合成多种新型功能化硬质/超硬材料，如超硬-超导电物质特性以及多种超硬半导体材料，通过高压中子衍射/同步辐射等手段确定其精确的晶体结构及高压力学行为，探索超硬相的内在物理结构模型；突破了传统力学强化的瓶颈，提出了通过高压实现晶体强化的力学理论。

3. 在绵阳研究堆搭建国内第一套集成低温、气体高压的中子衍射样品环境；利用原位高压中子衍射技术研究新能源气体笼型水合物的高压结构以及反应动力学模型，提出了客体分子尺寸、极性与水分子在形成水合物过程中相互作用的物理机制，为水合物在能源和环境领域的应用提供了重要的理论依据。发现水的液-液相变行为，对于深刻认识氢键具有重要意义。
