Self-Healing and Anti-Corrosion Coatings

Brief

An innovative method to make highly efficient coatings

Technology Overview

Self-healing coatings are a beneficial solution to existing corrosion issues in various industries, especially in oil & gas fields. The present invention includes the fabrication of a self-healing polymer coating incorporated with corrosion inhibitor encapsulated mesoporous carbon (MeC) based nanocontainer for the corrosion protection of metal structures. A corrosion inhibitor was added directly into the pores of mesoporous carbon and then covered by a polyelectrolyte layer to prevent the unwanted release. Pores of mesoporous carbon are effectively filled with a sufficient amount of benzotriazole, and they get released at the damaged area occurring by the triggering action of corrosion. This helps in diminishing the propagation of corrosion processes through the metal surface.

Brief

Providing access to fresh water in areas of scarcity

Technology Overview

Water is one of the most important resources in the world, however there is scarce access to fresh water in some locations. The developed device can be used for collecting water from the atmospheric moisture with no without energy input except for solar radiation. The device is comprised of a water absorbing material, a protection wall and a water container. When the water absorbing material is below phase separation temperature, hydrogen bonds are formed with water molecules resulting in the absorption of water from the air.

Brief

Enhancing the structure of molybdenum disulfide

Technology Overview

Sulfur-containing compounds are by-products from oil and gas production. Molybdenum disulfide is the preferred catalyst for hydro-desulphurization, which is the catalytic chemical process to remove sulfur from natural gas or other refined chemical products. However, molybdenum disulfide is limited to the surface area of the material. The developed process expands the surface area of the material by increasing the porosity and internal cavities of the material.

Brief

Single-atom and sub-1 nm probe for highly focused electron and ion beam microscopy and nano-probe microscopy.

Technology Overview

Nano-probes are the most critical parts in all scanning probe microscopes, like atomic force microscopes and scanning tunneling microscopes, as the resolution of the microscope is a direct function of the probe apex size, where optimum resolution can be achieved by having extremely sharp probes. These atomically sharp nano-probes can be used for characterizing and manipulating, bio and chemical molecules, nanomaterials. In electron and ion microscopes like scanning electron microscope (SEM), and ultra-high resolution transmission electron microscope (UHTEM), nanoprobes
are used as a source of electrons and ions where highly focused electron and ion beams can be produced.

Brief

Sustainable solution for product packaging and other applications

Technical Overview

Convenience, safety, low price, and good aesthetic qualities are among the major factors that make plastics useful for numerous applications. Synthetic polymers that are produced from petrochemical products have low recovery/reproduction rates and are not easily degraded in the environment. The developed method in the present technology is used to make a biodegradable composite using an aqueous mixture comprised of partially hydrolyzed cellulose in a dissolution media; combing the mixture with a solution of aliphatic polyester in a polar organic solvent;
removing solvent and dissolution media to form a wet biodegradable composite; and drying the wet biodegradable composite to form a dry biodegradable composite.

Innovative Self-Cleaning and Antifogging Coatings for Glass Substrates

Brief

Antifogging glass technology to tackle dirt and grim on glass

Technology Overview

The fabrication of (titanium dioxide) TiO2 coatings deposited by e-beam evaporation was achieved, with the ability to induce the production of self-cleaning superhydrophilic glass without the need for UV irradiation. After being annealed at 500 °C, the non-porous films exhibited radiation-free superwetting behavior. The superhydrophilic and antifogging
properties, which can be reactivated by a thermal treatment or prolonged through UV exposure, confirmed the excellent potential of these materials for self-cleaning application, both outdoors and indoors. The deposition of a 20 nm layer did not alter the optical and mechanical properties of the glass. In addition, film adhesion to the substrate and photocatalytic activity proved to be very effective. The prepared 20 nm coating (20-TiO2-GLASS) shows enhanced antifogging properties compared to bare glass and the commercial self-cleaning glass

Multi-chamber reactor for converting waste oil into biofuel

Technology Overview

Biodiesel is an important alternative fuel that includes a fatty acid methyl or (ethel) esters produced from trigylcerides as the product of vegetable, lipid, animal, trapped grease, or recycled cooking oil. However, production of biodiesel is limited due to current production methods. The developed multi-chamber continuous tubular reactor for the transesterification of oil can improve production. The multi-chamber design operates in a helical flow pattern to enhance mass transfer and increase conversion.
