Special Issue Information

Dear Colleagues,

Sensitive materials and sensing technology are at the interface of human society and the physical world. The unique compositions and structures render these materials responsive to ambient stimuli, such as chemical, light, temperature, electric voltage or current, mechanical stress, magnetic field, etc. Additionally, sensing technology offers various methods of utilizing these materials in solving the analytical problems of medicine, environment, food, industries, and security. The newly emerging nanotechnology and multidisciplinary intersection provide new opportunities in sensitive materials and sensing technology.

The scope of this Special Issue encompasses but is not limited to:

  • The design and synthesis of sensitive materials with novel sensing properties;
  • The design, fabrication, and optimization of (bio)sensors with an outstanding sensing performance;
  • Novel (bio)sensing concepts, mechanisms, and detection methods;
  • Advances of instrumental analysis, lab-on-a-chip, nanopores, etc.

The crevice corrosion of the 7075-T651 aluminium alloy was investigated using in situ electrochemical impedance spectroscopy (EIS), potentiodynamic polarization curves (PC), and H+ sensors in acidic NaCl solution with different contents of NaNO3. In the solution without NaNO3, the pH in the crevice increased rapidly and gradually reached a relatively stable status. The corrosion of the aluminium alloy in the crevice was inhibited and crevice corrosion could not be initiated. In the solution with NaNO3, the pH increased rapidly at the initial immersion period and then decreased gradually. The corrosion of the aluminium alloy inside the crevice could be enhanced and the corrosion of the aluminium alloy outside crevice could be inhibited. This triggered crevice corrosion in the solution with NaNO3. The inhibited corrosion outside the crevice can be attributed to the improved passive film of the specimen outside the crevice by nitrate. The accumulated secondary products of ammonia inside the crevice led to selective dissolution of copper, which triggered the nucleation of pitting corrosion and promoted the corrosion of the specimen inside the crevice.
