Experimental Determination of Damage Threshold Characteristics of Ir Compatible Optical Materials∗

Determination of the electrical percolation threshold of Polystyrene-Graphene Oxide nanocomposite using the experiment and simulation methods

Carbon nanostructures via adding to a polymer matrix, while improving the electrical, mechanical and optical properties of the nanocomposites, are widely used in the industry, medicine, and agriculture. The authors presented several investigations on a new type of gamma dosimeter based on the polymer-carbon nanostructures nanocomposite. In this research, the electrical percolation threshold of ...

Using Temperature of IR Sources for Assessing Photochemical and Aphakic Retinal Hazard

Introduction Blue light is a part of the spectrum with the highest energy content, which can reach the retina. The damage that it can cause to the retina is called photochemical or blue-light retinal injury. For the retinal injury assessment of the photochemical and aphakic retinal hazards in the wavelength range of 300-700 nm, use of effective spectral radiance limits (W.m-2.sr-1) seems to be ...

Transmission of CO2 Laser Radiation Through Glass Hollow Core Microstructured Fibers

In this chapter we would like to highlight and analyze the main problems of transmission and propagation of CO2 laser radiation in the hollow core microstructured fibers (HC MFs). It is well known that there is a strong need for the fiber delivery systems for 10.6 μm CO2 lasers due to a wide range of CO2 laser applications in medicine, spectrometry, industry, military applications and in other ...

Evaluation and Determination of the Salt Tolerance Threshold of Some Fenugreek (Trigonella foenum-graecum) Ecotypes at Seedling emergence Stage

Extended Abstract Introduction: Fenugreek, is a medicinal plant that has been considered as a salt tolerant crop. This research was conducted to investigate the effects of salt stress on seedling emergence characteristics and determination of the salt tolerance threshold, declivity of emergence and salt tolerance index of some fenugreek ecotypes. Material and Methods: Seeds of five ...
