The time-temperature indicator (TTI) developed by immobilizing laccase on electrospun fiber film with high specific surface area. The activation energycoloration of laccase TTI can be adjusted by pHaddition level of laccaseNaN3. This TTI exhibits high accuracy, stability, temperature reversibilitylow cost. The intelligent food packaging developed by this TTI can reduce the food wastethe food safety risk in traditional packaged foods.

An integrated solar photovoltaic-driven electrochemical water treatment technology have been developed with many advantages such as high energy independence, versatilityportability. The technology consists of photovoltaic systemelectrocatalytic/electrosorption processes, regarded as an innovative, energy-efficient water treatment system to remove organic pollutantscharged ions.
