A co-assembly method for synthesizing inverse photonic structures is described. The method includes combining an onium compound with a sol-gel precursor to form metal oxide (MO) nanocrystals, where each MO nanocrystal has crystalline and amorphous content. The MO nanocrystals are combined with templating particles to form a suspension. A solvent is evaporated from the suspension to form an intermediate or compound product, which then undergoes calcination to produce an inverse structure.

Disclosed herein are embodiments of high Q, temperature stable materials with low dielectric constants. In one aspect, a low loss dielectric material includes one or more transition metal oxides based on the (Zn, Ni, Co)O—Al.sub.2O.sub.3—TiO.sub.2 system comprising an aluminate comprising one of cobalt (Co) or nickel (Ni) crystallized in a spinel structure. The low loss dielectric material additionally comprises one or more of: a titanate comprising the one of Co or Ni crystallized in a spinel structure, an aluminum oxide and a titanium oxide crystallized in a rutile structure.

A composition includes aluminum hydroxide gel and a conjugate of at least one CysA13(33-40) peptide linked to the keyhole limpet hemocyanin (KLH). Maleimidobutyric acid Nhydroxysuccinimide ester (SM) serves as cross-linking agent. The composition can produce an effective and specific immune response against Aβ40. The antibodies produced are specific for Aβ40 without significantly binding to Aβ42. The composition can increase the response against Aβ40 compared with the response produced by other conjugates that include CysAβ(33-40) peptide and KLH, and are bound or conjugated by other crosslinking agents.

Methods for preparing a layered metal nanocomposite and a layered metal nanocomposite. The method includes mixing a magnesium salt and an aluminum salt to form a Mg.sup.2+/Al.sup.3+ solution. The Mg/Al has a molar ratio of between 0.5:1 to 6:1. Then a diamondoid compound is added to the Mg.sup.2+/Al.sup.3+ solution to form a reactant mixture. The diamondoid compound has at least one carboxylic acid moiety. The reactant mixture is heated at a reaction temperature for a reaction time to form a Mg/Al-diamondoid intercalated layered double hydroxide. The Mg/Al-diamondoid intercalated layered double hydroxide is thermally decomposed under a reducing atmosphere for a decomposition time at a decomposition temperature to form the layered metal nanocomposite.
