Physical‐chemical Test Platform for Room Temperature,Far‐infrared Ray Emitting Ceramic Materials (cFIR)

Ceramic far‐infrared (cFIR) emitting materials are sources of room temperature FIR radiation that allow non‐thermal irradiation of biological tissue. In this study, we explored some interesting physical and chemical effects that have not been reported. We investigated the effects of cFIR irradiation of sorghum wine using gas chromatography with solid‐phase micro‐extraction (GC‐SPME) to demonstrate enhancement on volatility; monitored pH changes resulting from irradiation on acetic acid; and used UV spectroscopy to identify and quantify chemical changes. On the basis of the results, we deduced that cFIR possesses the ability of weakening hydrogen bond and exhibits chemical reduction change. The methods above provide a relatively convenient and cost‐effective test platform to demonstrate the application of cFIR as an effective alternative to biological assay.     

The Physical,Chemical and Biological Effects by Room Temperature Ceramic Far‐infrared Ray Emitting Material Irradiated Water: A Pilot Study

Far infrared ray (FIR) is non‐ionizing electromagnetic radiation with wavelengths of 4‐16 μm. Ceramic far infrared ray emitting materials (cFIR) are sources of FIR that exhibit only non‐thermal effects at room temperature. Certain physical, chemical and biological effects of cFIR irradiation were investigated in this study that heretofore has not been well characterized. We demonstrated that cFIR irradiation reduced the size of water clusters, and significantly increased the freezing temperature of water. We also observed an increase in the volatility of a complex mixture of alcohol, water and solutes and recorded elevated total phenol in green tea infusions prepared using cFIR irradiated water. The effects of cFIR irradiated water on living cells were also investigated. The MC3T3‐E1 murine osteoblast cells grown in the presence of cFIR irradiated water exhibited anti‐oxidative effects on H₂O₂‐mediated toxicity, as evidenced by late stage increase in intracellular alkaline phosphatase. The presence of cFIR irradiated water also resulted in significant decrease in COX‐2 production in the chondrosarcoma cell line, SW1353, in response to lipopolysaccharide induction. Based on our findings, the possible anti‐inflammatory effects of cFIR irradiated water and implications of our study with regard to bone and joint health were discussed.
