Evolution of self-assembled Bi2O3/LDHs nanostructures to mixtures of mixed oxides and their photocatalytic efficiency under UV and solar light

Katsumata K-I, Puscasu M., Seftel E., Grosu E.F., Ikeda K., Cool P., Carja G., Technical University Gheorghe Asachi of Iasi, RO

Self-assemblies of nanoparticles of Bi2O3 and the clay matrices of layered double hydroxides (LDHs) were fabricated using the manifestation of the structural memory effect of the LDHs in Bi(NO3)3 aqueous solutions, at room temperature. Nanoparticles [...]

Drug delivery system based on inorganic layered materials

Cunha V.R.R., Petersen P.A.D., Petrilli H.M., Constantino V.R.L., University of Sao Paulo, BR

Layered Double Hydroxides (LDHs) are well known inorganic carriers which have been explored during the development of new materials for medicinal and pharmacological applications. The solubility and chemical stability of guest species can be increased [...]

Layered nanocomposites of plate-like particles and polymers

Zhang Y., Evans J.R.G., University College London, UK

Clay-polymer nanocomposites have emerged as a new class of material in recent years because a low addition of clay (<5 wt.%) in a polymer matrix causes significant improvement in material properties. They represent the low [...]

On-demand release of corrosion-inhibiting molecules from layerd double hydroxide film formed on magnesium alloy

Ishizaki T., Teshima K., Saito N., National Institute of Advanced Industrial Science and Technology (AIST), JP

Magnesium is one of the lightest engineering materials. Thus, it is expected that magnesium and its alloys are applied to aerospace, aircraft, automobile, and railway. However, they have a defect which is extremely low corrosion [...]

Preparation and Characterization of New Lanthanide materials: Layered Double Hydroxide Intercalated by Luminescent Polyoxometalate Anions with Dawson-like [Eu(H2O)3(a2-P2W17O61]7- and Keggin-like [Eu2(H2O)2(PW11O39)]4-

Zhang C., Howell R.C., Xu W., Luo Q-H, Akins D.L., Francesconi L.C., Hunter College, US

Dawson-like [Eu(a1-P2W17O61]7-and Keggin-like [Eu2(PW11O39)2]8-were first isolated and x-ray crystallized in our group. In relation to previous work, we are interested in synthesizing new lanthanide materials by incorporating the title polyoxometalates (POMs) anions into layered double [...]
