In the electromagnetic spectrum, structural damage to living tissues per unit of absorbed energy tends to increase with the decrease of a wavelength which is evident not only for ultraviolet and ionizing radiation but also for the infrared and visible light. By causing thermal damage after absorbing energies that would be harmless for radiofrequency electromagnetic fields (EMF), tissues are eve...

in this research, cobalt and nickel sulfide nanoparticles (nps) were grown on almcm-41 matrix by using ion exchange method. the prepared samples were irradiated by thermalized neutron that emitted from am-be source up to fluencies (7.9+e9n/cm2). after that, x-ray diffraction (xrd), uv-vis spectroscopy, fourier transform infrared (ftir), scanning electron microscopy (sem) and transmission electr...

A novel MEMS thermopile structure is presented, which consist of linearly arranged pand ntype polysilicon strips instead of the conventional loop-like configuration. It is shown that these devices sense the millimeter wave radiation beyond the infrared. The polarity and frequency dependence of the sensitivity prove that these strips behave as absorbing antennas towards the microwave/millimeter ...

A facility to generate high-intensity, ultra-short pulses of broad-band far-infrared radiation has been assembled and tested at Stanford.’ The device uses sub-picosecond relativistic electron bunches to generate coherent radiation through transition or synchrotron radiation in the far-infrared (FIR) regime between millimeter waves and wavelengths of about 100pm and less. Experimental results sh...

The paper analyses the selected optical parameters of protective optic filters used for protection of the eyes against hazardous radiation within the visible (VIS) and near infrared (NIR) spectrum range. The indexes characterizing transmission and reflection of optic radiation incident on the filter are compared. As it follows from the completed analysis, the newly developed interference filter...

ST25 is a key acupoint used in the treatment of ulcerative colitis by moxibustion stimulation, but the biophysical mechanism underlying its effects is still unknown. The aim of the present study was to explore the biophysical properties of ST25 acupoint stimulated by moxibustion in a rat model of ulcerative colitis. The infrared radiation intensity of fourteen wavelengths of ST25 showed signifi...
