  2. Lanthanum strontium manganite - Wikipedia

    en.wikipedia.org/wiki/Lanthanum_strontium_manganite

    Lanthanum strontium manganite (LSM or LSMO) is an oxide ceramic material with the general formula La 1−x Sr x MnO 3, where x describes the doping level. It has a perovskite -based crystal structure, which has the general form ABO 3 .

  3. Strongly correlated material - Wikipedia

    en.wikipedia.org/wiki/Strongly_correlated_material

    The perovskite structure of BSCCO, a high-temperature superconductor and a strongly correlated material.. Strongly correlated materials are a wide class of compounds that include insulators and electronic materials, and show unusual (often technologically useful) electronic and magnetic properties, such as metal-insulator transitions, heavy fermion behavior, half-metallicity, and spin-charge ...

  4. Metal–organic framework - Wikipedia

    en.wikipedia.org/wiki/Metal–organic_framework

    The aluminum oxide layer serves both as an architecture-directing agent and as a metal source for the backbone of the MOF structure. [33] The construction of the porous 3D metal-organic framework takes place during the microwave synthesis, when the atomic layer deposited substrate is exposed to a solution of the requisite linker in a DMF /H 2 O ...

  5. Sol–gel process - Wikipedia

    en.wikipedia.org/wiki/Sol–gel_process

    The method is used for the fabrication of metal oxides, especially the oxides of silicon (Si) and titanium (Ti). The process involves conversion of monomers in solution into a colloidal solution ( sol ) that acts as the precursor for an integrated network (or gel ) of either discrete particles or network polymers .

  6. Oxide dispersion-strengthened alloy - Wikipedia

    en.wikipedia.org/wiki/Oxide_dispersion...

    The oxide particles instead are stable in the matrix, which helps prevent creep. Particle stability implies little dimensional change, embrittlement, effects on properties, stable particle spacing, and general resistance to change at high temperatures. [5] Since the oxide particles are incoherent, dislocations can only overcome the particles by ...

  7. Charge ordering - Wikipedia

    en.wikipedia.org/wiki/Charge_ordering

    Charge ordering (CO) is a (first- or second-order) phase transition occurring mostly in strongly correlated materials such as transition metal oxides or organic conductors. Due to the strong interaction between electrons, charges are localized on different sites leading to a disproportionation and an ordered superlattice.

  8. Strengthening mechanisms of materials - Wikipedia

    en.wikipedia.org/wiki/Strengthening_mechanisms...

    The dislocations in a material can interact with the precipitate atoms in one of two ways (see Figure 2). If the precipitate atoms are small, the dislocations would cut through them. As a result, new surfaces (b in Figure 2) of the particle would get exposed to the matrix and the particle-matrix interfacial energy would increase.

  9. Metallic bonding - Wikipedia

    en.wikipedia.org/wiki/Metallic_bonding

    Therefore, plasmons are hard to excite on a bulk metal. This is why gold and copper look like lustrous metals albeit with a dash of color. However, in colloidal gold the metallic bonding is confined to a tiny metallic particle, which prevents the oscillation wave of the plasmon from 'running away'. The momentum selection rule is therefore ...
