background: cutaneous leishmaniasis caused by l. major is an important public health problem in endemic areas. the aim of this study was to explore the therapeutic effect of microwave and or infrared radiation in the treatment of lesion induced in balb/c mice by l. major inoculation. methods: the footpad lesion was induced in balb/c mice by inoculation of l. major promastigotes subcutaneously. ...

abstract background: in recent years, infrared thermography tools are used for viral disease detection. however, no study has been to evaluate the value of this device. the current study was designed to review the effectiveness of infrared thermography technique for diagnosis of viral diseases in international airports. materials and methods: this study was conducted as a systematic review. all...

In this letter, we present a nanophotonic device consisting of plasmonic nanopatch array (NPA) with integrated metal-organic framework (MOF) for enhanced infrared absorption gas sensing. By designing a gold NPA on a sapphire substrate, we are able to achieve enhanced optical field that spatially overlaps with the MOF layer, which can adsorb carbon dioxide (CO2) with high capacity. Experimental ...

We demonstrate a new class of semiconductor device: the optically triggered infrared photodetector (OTIP). This photodetector is based on a new physical principle that allows the detection of infrared light to be switched ON and OFF by means of an external light. Our experimental device, fabricated using InAs/AlGaAs quantum-dot technology, demonstrates normal incidence infrared detection in the...

The Anti–Collision device is a detection device meant to be incorporated into cars for the purpose of safety. As opposed to the anti–collision devices present in the market today, this system is not designed to control the vehicle. Instead, it serves as an alert in the face of imminent collision. The device is intended to find a way to implement a minimum spacing for cars in traffic in an affor...

We demonstrated that modulated infrared radiation can cause the resonant excitation of plasma oscillations in quantum well diode and transistor structures with high electron mobility. This effect provides a new mechanism for the generation of tunable terahertz radiation using photomixing of infrared signals. We developed a device model for a quantum well photomixer and calculated its high-frequ...
