L-alanine potassium nitrate (LAPN) single crystal was grown by slow evaporation solution growth technique. The lattice parameters of the crystals were determined X-ray diffraction Fourier transform infrared (FT-IR) study reveals that functional groups present in crystal. UV-Vis-NIR studies carried out to find transmittance and other optical parameters. Vicker’s microhardness test estimate mecha...

This study is an initial investigation on the capability of multispectral imaging to capture subtle spectral information that would enable the automatic delineation between the eosinophilic esophagitis and other eosin stained tissue components, especially the RBCs. In the method, a principal component analysis (PCA) was performed on the spectral transmittance samples of the different tissue com...

This paper is the first multi-scale characterization of the fluidize-dried gum extracted from the fresh fruits of the plant Abelmoschus esculentus. It describes the physical, thermal, sorptional and functional properties of this natural gum. Elemental analysis, scanning electron microscopy (SEM), particle size analysis, X-ray powder diffraction (XPRD), thermo-gravimetric analysis (TGA), differe...

objective: some of the adverse effects of aspirin including peptic ulcers, gastrointestinal bleeding and aspirin resistance compelled researchers to find a suitable alternative with fewer adverse effects. in this clinical trial, we aimed to find the effective antiplatelet dose of garlic. materials and methods: this randomized controlled clinical trial (rct) was conducted on 62 healthy volunteer...

NiMoO(4) nanorods have been successfully synthesized by sonochemical method process by using Ni(CH(3)COO)(2) · 4H(2)O and (NH(4))(6)Mo(7)O(24) · 4H(2)O as starting materials. Some parameters including ultrasonic power, ultrasonic irradiation time, stirring effect, solvent effect, and surfactant effect were investigated to reach optimum condition. The as synthesized nanostructures were character...

The advancement of far-ultraviolet (FUV) coatings is essential to meet the specified throughput requirements of the Large UV/Optical/IR (LUVOIR) Surveyor Observatory which will cover wavelengths down to the 100 nm range. The biggest constraint in the optical thin film coating design is attenuation in the Lyman-Alpha Ultraviolet range of 100-130 nm in which conventionally deposited thin film mat...

Potassium tetraborate tetrahydrate (KTBTH) single crystals were grown by slow evaporation solution growth method at room temperature. The grown crystal was characterized by single crystal X ray diffraction analysis. FT – IR and FT – Raman spectra were recorded to identify the functional groups. Optical transmission and absorption spectral studies were carried out to test the transmittance of th...

The optical constants in the ir from lambda2.5 microm to 40 microm (4000-250 cm(-1)) of dry natural aerosol substances and of sea salt are presented. The aerosol substances were obtained from rain and snow water: dust and soot by sedimentation, and water soluble salts by evaporation. The spectra of the absorption index n' were derived from our published transmittance measurements of potassium b...

An integrating-sphere system has been designed and constructed for multiple optical properties measurement in the IR spectral range. In particular, for specular samples, the absolute transmittance and reflectance can be measured directly with high accuracy and the absorptance can be obtained from these by simple calculation. These properties are measured with a Fourier transform spectrophotomet...
