Gain-swept superradiance applied to the stand-off detection of trace impurities in the atmosphere.
نویسندگان
چکیده
We show that gain-swept superradiance can be used to detect low (parts per million) concentrations of various gases at distances on the order of kilometers, which is done by using pulse timing to create small regions of gain at positions that sweep toward a detector. The technique is far more sensitive than previous methods such as light detection and ranging or differential absorption light detection and ranging.

Stability-indicating UFLC method for uncoupling and estimation of impurities in clopidogrel, aspirin and omeprazole in their tablet dosage form using PDA detection
In this paper a fast and novel stability-indicating ultra fast LC method for separation and estimation of impurities in clopidogrel and aspirin in their combined tablet dosage form and omeprazole was developed. The separation of USP related substances of clopidogrel (A, B and C), aspirin (D), omeprazole (A, B and C) and few other unknown impurities was detected by using ultra fast liquid chroma...
متن کاملEffect of impurities on the optical properties of KTP single crystals grown from flux
In the present work, KTP crystals have been grown by spontaneous nucleation technique in flux medium using K6P4O13 flux. 0.4-1 °C/h cooling rates were applied in the spontaneous nucleation process. The presence and amount of impurities has been determined by using XRF. The optical transmission spectra of impure KTP crystals in the UV–visible region are discussed. The transmission cut-off is cle...

Blood selenium and trace minerals play an important role in animal’s health and production. The aims of this study were to determine selenium effect on blood glutathione peroxidase (GPX) activity, trace minerals and weight gain in lambs. Twelve female Makuei breed were studied for 63 days in groups of control, nanoselenium (NanoSe) and sodium selenite (NaSe). Mean concentrations of GPX, Cu and ...
متن کاملApplication of Rapid and Sensitive Real Time PCR Technique in Detection of DNA Impurities in Recombinant Interferon
Background & Objective: Interferon belongs to a family of cytokines, which has the most important role in the innate immune response to virus infections. While producing recombinant interferon in biological host, some pieces of host nucleic acids remain in product. Because of limitations in previous techniques for detection of these impurities, the objective of this study is to use rapid ...

In this research, the high-energy planetary mill was employed to produce nanocrystalline Ti-50Al(γ)(at%) powders. Initial powders were mechanically alloyed in 99.9999% and 90% purities of Argon and also Air atmosphere with alloying times up to 50h. The effect of impurity of Argon atmosphere on the microstructure and the rate of phase transformation of Ti-50Al were investigated during mechanical...
