The objective of this paper deal with the physico chemical aspects of certain colouring plants namely. Bixa orellana Linn. (Leaves) and Lawsonia inermis Linn (Leaves). The determined data under the physico chemical, chromatographic and spectrophotometric studies can be taken as a pharmacopoeial standards.

A new class of compounds, called as ionic liquids, has recently emerged as potential substitute for volatile organic solvents. Ionic liquids possess certain special physico-chemical characteristics that render them very useful in different areas of research and development. In this review, the physico-chemical properties and the applications of ionic liquids in chemical processes are critically...

Present work focused on the seasonal variations in the physico-chemical parameters of the freshwater temple pondPrayagtirth at Trimbakeshwar in Nashik district during summer, monsoon and winter. A total 15 parameters were analysed and their seasonal variation is discussed. The correlation matrix of the various physico-chemical parameters are computed and analysed.

Djendjen River is one of the largest rivers in the region of Jijel (Algeria). Human activities such as urban discharges, industrial, agricultural, and livestock have significant effects on the quality of water. The present study attempts to evaluate the quality of water along the banks of the Djendjen River at different sampling sites, using physico-chemical and bacteriological methods. The col...

In this short writing I tried to describe my all-life positive experience with the University of Chemical Technology (UCT) Prague, starting from student age till now, adult age. At UCT, met many amazing people not only when was a but especially as researcher and an academic person. am very grateful for all collaborations them: firstly in field estimation various physico-chemical properties chem...

Silver nanoparticles were obtained via totally green synthesis from silver nitrate using glucose as reducing agent and sucralose as capping agent. Physico-chemical characterization of AgNPs was performed by UV-Visible absorption and transmission electron microscopy (TEM) in order to correlate biological/toxicological responses with AgNPs features. A detailed study of silver nanoparticles (AgNPs...

Microscopic and physico-chemical methods were used for a comprehensive surface characterization of different mechanically modified stainless steel surfaces. The surfaces were analyzed using high-resolution confocal microscopy, resulting in detailed information about the topographic properties. In addition, static water contact angle measurements were carried out to characterize the surface hete...

The effect of a Nd: YAG laser (1064 nm) has been studied on Ti6Al4V alloy in terms of optical and physical parameters for biomedical applications. The superior surface microhardness hardness (i.e. 377 VHN) is attributed to grain refinement associated with laser melting and rapid solidification. The electrochemical property, mainly pitting corrosion resistance, has been carried out in Hanks salt...
