In this paper, we introduce a novel – physico-chemical – approach for calibration of a digital camera chip. This approach utilizes results of measurement of incident light spectra of calibration films of different levels of gray for construction of calibration curve (number of incident photons vs. image pixel intensity) for each camera pixel. We show spectral characteristics of such corrected d...

A series of LiNbO3:Tb ([Tb] = 0.1–2.89 wt%) and a nominally pure near-stoichiometric (NSLN) crystals have been grown. Concentration dependences physico-chemical structure characteristics different composition has studied.

Silver nanoparticles (AgNPs) are extensively used in various industries due to their unique physico-chemical and antimicrobial properties. Many natural biomolecules in plants (inactivated plant tissue, plant extracts and living plant) such as proteins/enzymes, amino acids, polysaccharides, alkaloids, alcoholic compounds, and vitamins could be involved in bioreduction, formation and stabilizatio...

Natural polymers are widely used in pharmaceutical formulations. They are biodegradable and generally nontoxic in nature. In this review pharmaceutical application of rosin is characterized. Rosin is a natural non-volatile resinous mass obtained from Pinus palustris. Physico-chemical characteristics and ease of availability of rosin provide a platform to use it as a polymer for different drug d...
