The present invention relates to a silicon dioxide composite particle with far-infrared radioactivity, which is formed by the hydrolysis, condensation and polymerization of an organic silane precursor having the structure of the formula (I) with a tetra-alkoxysilane. The high stability of organic silane precursor compounds and the low biotoxicity of silicon dioxide composite particles make the present far-infrared radioactive silicon dioxide composite particles of great potential for extensive use in related bio-products.

Silica-including microcapsule resin particles including an outer shell constituted of a crosslinked polymer and a cavity partitioned with the outer shell, in which the silica-including microcapsule resin particles contain inside the cavity a porous structure in which silica particles are mutually connected, and have a volume average particle diameter of 0.5 to 100 μm.

Commercially beneficial carbon-containing fractions can be recovered from hydrothermal liquefaction reactions in various types of processors. Feedstock slurry from waste solids is placed into a pressurized processor where it is maintained at temperature and pressure for a predetermined period. On discharge from the processor the processed discharge is separated into liquid and solid fractions. Gaseous fractions including carbon dioxide can also be removed or off-taken from the processor. New molecular structures are created in this reaction, resulting in fractions including biogas, biofuels, biosolids and biocrude. Silica, phosphates, potash and low concentration nitrogen based fertilizer, along with carbonaceous material can also be recovered.

This invention refers to a technically and economically viable process for recovery of relevant metallic and non-metallic contents from mining residues, particularly the bauxite residue, using it in its integral form. Such a process route uses energy from microwaves, assisted leaching and logic sequencing of steps that allow a technically and economically viable removal of components from the bauxite residue, particularly the residue from the Bayer process. The invention also refers to a microwave reactor that is appropriate for performing the above-mentioned process, as well as to a method for heating a mining product.

A durable, hydrophobic and anti-scratching nano-coating for coating on a glass substrate or surface having a water contact angle of about 90° or more, a reduced coefficient of friction by 50% or more, and a reduced surface roughness compared to those of the glass substrate or surface without the nano-coating is provided, which includes a layer of fluorinated silica derived from sol-gel hydrolysis between one or more tetraalkoxysilanes having at least three alkoxy groups and one or more polyfluorinated silanes having at least a trialkoxysilane and from 15 to 17 fluorine atoms in the presence of a catalyst to a reaction mixture of the sol-gel hydrolysis between the one or more tetraalkoxysilanes and the one or more polyfluorinated silanes, and a solvent. A related method of fabricating the nano-coating via atomization of acid-containing or alkali-containing solution and sol-gel precursor solution onto the glass surface is also provided.

A pyrolysis method and a pyrolysis reactor for recovering silica from a polymer waste material containing silica, particularly a rubber or plastics waste material containing silica, using thermal decomposition for separating silica from at least one non-silica component of the polymer waste material, are disclosed. The waste material is delivered to a pyrolytic chamber, and heated to a decomposition temperature of at least one non-silica component of the waste materiel by microwave radiation. The decomposition temperature is selected such that the at least one non-silica component includes a higher microwave absorptivity than silica.
