In the present research work, an anatase structure titanium dioxide nanoparticle was synthesized by hydrolysis of titanium isopropoxide in the presence and absence of ultrasonication. The resultant product suspension was peptized for getting narrow size distribution. The synthesized nanoparticles are used for preparation of nanofluids with different volume percent loading of nanoparticles in water ranging from 1% to 5%. The characterization of particles was carried out by TEM, XRD. Our result shows that the use of ultrasonic technique has a significant effect on the homogeneity and then size of TiO2nanoparticles. Viscosity of nanofluids was demonstrated with rheometer (TA instruments). Viscosity results confirmed Newtonian behavior of nanofluids and showing increasing trends with addition of nanoparticles in base fluids. The dispersion of nanoparticles in nanofluids is studied with unique method of UV visible spectrophotometer, which confirm good dispersion stability prepared nanofluid of 50 hrs.

Drug delivery system is a system that describes the journey of a drug to its target location. The main component of the drug delivery system is gelatin. The leaves of grass jelly-seaweed are needed as a raw material for gelatin. The main component of gelling agents in grass jelly leaves and seaweed is a low-methoxy pectin polysaccharide. Pectin from previous study is used as a synthesis material for hard capsule shells with the addition of other ingredients, which are Na-CMC, sorbitol, and water. The characterization results of capsule shells with variations in the composition of grass jelly-seaweed leaves 0: 4, 1: 3, 2: 2, 3: 1, and 4: 0 (A, B, C, D and E) have a disolving time of 12 minutes 45 seconds; 15 minutes 53 seconds; 23 minutes 10 seconds; 15 minutes 35 seconds and 18 minutes 12 seconds. The swelling degree test each of 200%; 266,7%; 303.3%; 586.7% and 643.3%. Furthermore, the shells of grass jelly-seaweed leaf capsules were tested for their material performance in the cefadroxyl disolving test with variations in sampling time of 10, 20, and 30 minutes. Keywords: Cefadroxyl, Drug delivery system, Green grass jelly leaves, Non-gelatin capsules, Seaweed

In this work, experimental methods used for the evaluation of stability of solids in liquids dispersions, are presented. For the characterization of dispersion components, modern analytical techniques, such as tensiometry, scanning and static turbidimetry, have been applied. The influence of selected surface active substances on the dispersion stability was demonstrated.

Mycobacteriophage R1 was originally isolated from a lysogenic culture of M. butyricum. The virus was propagated on a leucine-requiring derivative of M. smegmatis, 607 leu−, isolated by nitrosoguanidine mutagenesis of typestrain ATCC 607. Growth was accomplished in a minimal medium containing glycerol and glucose as carbon source and enriched by the addition of 80 μg/ ml L-leucine. Bacteria in early logarithmic growth phase were infected with virus at a multiplicity of 5, and incubated with aeration for 8 hours. The partially lysed suspension was diluted 1:10 in growth medium and incubated for a further 8 hours. This permitted stationary phase cells to re-enter logarithmic growth and resulted in complete lysis of the culture.

Amorphous materials are of current interest due to their desirable mechanical, electrical and magnetic properties. Furthermore, crystallizing amorphous alloys provides an avenue for discerning sequential and competitive phases thus allowing access to otherwise inaccessible crystalline structures. Previous studies have shown the benefits of using AEM to determine crystal structures and compositions of partially crystallized alloys. The present paper will discuss the AEM characterization of crystallized Cu-Ti and Ni-Ti amorphous films.Cu60Ti40: The amorphous alloy Cu60Ti40, when continuously heated, forms a simple intermediate, macrocrystalline phase which then transforms to the ordered, equilibrium Cu3Ti2 phase. However, contrary to what one would expect from kinetic considerations, isothermal annealing below the isochronal crystallization temperature results in direct nucleation and growth of Cu3Ti2 from the amorphous matrix.
