The present disclosure provides a method of preparing unsaturated hydrocarbons by black body photocatalytic (thermal radiative catalytic) conversion of saturated hydrocarbons. In this method, a saturated hydrocarbon reaction gas is introduced into a reaction furnace, and the saturated hydrocarbon is catalyzed to convert under heating and illumination conditions to prepare the unsaturated hydrocarbons. The photocatalysis is combined to the conventional thermal catalysis to improve the catalytic performance, accelerate the reaction speed, increase the conversion rate, and/or improve the selectivity of the catalytic reaction.

At least one a first one of the photonic crystal materials may be configured to have a response to an external stimulus different from at least a second one of the photonic crystal materials, the different response resulting in a change in the reflected wavelength of the first photonic crystal material that is an optically detectable difference from the second photonic crystal material.

The present invention provides a new class of organic/inorganic hybrid materials having [ER]rings interconnected by E' atoms. In an embodiment a class of materials called high organic group content periodic mesoporous organosilicas (HO-PMO's) with [SiR]rings interconnected by O atoms is described. The measured dielectric, mechanical and thermal properties of the materials suggest that an increased organic content achieved by the [SiR]rings of a high organic group content periodic mesoporous organosilica leads to superior materials properties potentially useful for a wide range of applications including microelectronics, separation, catalysis, sensing, optics or electronic printing.

The present invention provides a synthetic strategy for creating a new class of materials called hybrid mesoporous, macroporous, or mesoporous-macroporous organometaloxide materials, exemplified but not limited to hybrid mesoporous organosilicas. This strategy involves taking a pre-assembled mesoporous material having a porous framework and then attaching an organic, inorganic or biological guest molecule to the pore walls of the framework material through two or more chemical linkages. The unusual combination of inorganic and organic components organized into a material with mesoscale porosity and having bridge bonded organic, organometallic, or biological functionalized surfaces suggests a myriad of uses for these composite materials, such as the controlled release and uptake of chemicals and drugs, chiral separations and catalysis, electronic printing and microelectronic packaging, thermal and acoustical insulation.

This invention describes methods of synthesis and applications of a composite material of a colloidal crystal and a substrate. The method includes steps of (a) providing a substrate having a surface with a surface relief pattern; and (b) applying a liquid dispersion containing colloidal particles onto the surface and spinning the substrate whereby colloidal particles are swept across the surface and self-assemble in void spaces on the surface defined by the relief pattern. The resulting composite material (substrate with colloidal crystal) may be used in various applications such as chromatography, for use in lab-on-chip based devices, micro-reactors and the like. The material may be infiltrated by a material and the composite inverted to remove the colloidal particles to produce an inverted colloidal crystal pattern on the substrate. The material may be selected such that the inverted colloidal crystal pattern is a photonic crystal.
