BACKGROUND Insect repellents are prophylactic tools against a number of vector-borne diseases. There is growing demand for repellents outperforming DEET in cost and safety, but with the current technologies R&D of a new product takes almost 10 years, with a prohibitive cost of $30 million dollar in part due to the demand for large-scale synthesis of thousands of test compounds of which only 1 m...

Atmospheric analysis by open-path Fourier-transform infrared (OP/FT-IR) spectrometry has been possible for over two decades but has not been widely used because of the limitations of the software of commercial instruments. In this paper, we describe the current state-of-the-art of the hardware and software that constitutes a contemporary OP/FT-IR spectrometer. We then describe advances that hav...

This lab had two objectives. First, we wished to image a variety of fluorescing single photon sources using a confocal microscopy setup. Second, we wished to detect photon antibunching using a Hanbury Brown & Twiss setup in at least one of the samples. We were able to successfully image samples of Single Walled Carbon Nanotubes, Nanodiamonds, Gold Nanoparticles, and Colloidal CdSe Quantum Dots,...


 The number of industries in a certain region is increasing year by due to the needs people, and therefore intelligent industrialization automation can be used. Here air quality industry products manufactured are monitored using gas detectors (to detect toxic or gases) IR sensors count manufactured) where there no need for labor. Also see estimated time arrival delivery vehicle GPS used g...

The proliferative responses of T cells, depleted of alloreactive cells, were tested upon stimulation by antigens presented on allogeneic antigen-presenting cells (APC). Restriction molecules involved in these responses were identified by inhibition of T cell proliferation with monoclonal antibodies against A(A alpha A beta) and E(E alpha E beta) molecules of the APC. The responses to all three ...

Silicon-based photodetectors are attractive as low-cost and environmentally friendly optical sensors. Also, their compatibility with complementary metal-oxide-semiconductor (CMOS) technology is advantageous for the development of silicon photonics systems. However, extending responsivity silicon-based to mid-infrared (mid-IR) wavelength range remains challenging. In developing mid-IR infrared S...

background: radon is an odourless, colourless and tasteless gas and it is the first cause of lung cancer among non- smokers. the assessment of the level of radium in building materials helps in understanding the radiological implications. it has been observed that everyone has some levels of exposure to them. therefore measurement of radium and radon in the soil samples are important from publi...

background: due to volatility of radioactive iodine solutions, usually internal exposure would occur in personnel that are working in nuclear medicine centers. the activities in the thyroid of individual s who work in nuclear medicine centers of north west provinces of iran were measured using nai (sodium iodide) detectors. in every center, nearly 40 - 500 mci of 131 i and 50 - 600 μ ci of 125 ...
