The vertical migration of M. incognita juveniles introduced at 20 cm from the roots was studied in five natural soils, 100% silica sand, 95% silica sand with 5% clay, 90% silica sand with 10% clay, and 95% silica sand with 5% clay as a concentrated layer. In natural soils the percentage of juveniles capable of migrating 20 cm and penetrating the roots decreased when the percentage of clay and s...

Water-dispersible Fe(3)O(4) nanoparticles have been prepared by a simple solution method, in which the particle size (3-11 nm) can be tuned by simply adjusting the reaction temperature and time; the formation mechanism of Fe(3)O(4) nanoparticles is proposed and their low cytotoxicity has also been proved.

A novel rhodamine-oxaldehyde (RHO) functionalized β-NaYF4:Yb(3+)/Er(3+) upconversion nanoparticle (UCNP) for specific detection of cysteine (Cys) in aqueous solution was achieved through a Förster resonance energy transfer (FRET) process. Based on self-assembling interaction, hydrophobic upconversion nanoparticles could be modified with α-cyclodextrin to make them water dispersible.

New amphiphilic ABC triblock copolymers have been designed and self-assembled into water-dispersible and biodegradable polymer micelles, which exhibit good antibacterial activities without quaternary ammonium moieties or the loading of any external antibiotics due to the increased local concentration of cationic charge in the polymer micelles compared to the un-self-assembled individual polymer...

A simple and scalable method has been developed for directly forming water-dispersible van der Waals solids involving mixing aqueous solution of graphene oxide (GO) with hexagonal boron nitride (BN) or molybdenum disulphide (MoS2) in N-methylpyrrolidone. The GO acts as an amphiphile in stabilising the colloidal solutions of the heterolaminar material in water.

Water dispersible single- and bilayered graphene sheets are produced by a direct exfoliation from graphite flakes in the presence of pyrene-labeled single stranded DNAs, and the immobilized DNA on the graphene surface is further hybridized with a gold nanoparticle labeled complementary DNA to generate gold nanoparticle-graphene nanocomposites.

Lamotrigine is a substituted asymmetric triazine. It is a white to pale cream-coloured powder. It is slightly soluble in ethanol and chloroform, and very slightly soluble in water. The pKa of lamotrigine at 25°C is 5.7. Each Lamictal Dispersible/Chewable tablet also contains calcium carbonate, hydroxypropyl cellulose, aluminium magnesium silicate, sodium starch glycollate, povidone, saccharin s...
