Abstract: A vanillin having a tetramer structure is revealed, comprising a first monomer, a second monomer, a third monomer, and a fourth monomer. Each of the monomers is constituted by C8H8O3. The vanillin includes a first intermolecular hydrogen bond between the first monomer and the fourth monomer, and a second intermolecular hydrogen bond between the second monomer and the third monomer to stabilize the tetramer structure.

Abstract: A knife structure, which comprises a knife body, a sheath for accommodating the knife body, an alert and rescue module, a plurality of LED light units disposed on the upper and lower edges of the sheath, a solar module and an energy-storing unit, wherein the alert and rescue module is disposed on the exterior of the sheath and includes an illumination module and a digital tool unit to aid in outdoor survival. Said digital tool unit is provided with a compass, a thermometer, a barometer, a music player and the like, and a solar module is disposed on the surface of the sheath for absorbing sunlight and heat to store electricity in the energy-storing unit to supply the required electricity.
