A safe method for the direct oxidation of methane and light alkanes to methanol and other oxygenates is disclosed. Selective catalytic oxidation can be a transformative technology for using increasing abundant natural gas, bio-gas and other sources of low value hydrocarbons via gas to liquid process.
The present invention provides decellularized cartilage (DCC) fragments or powder as a raw material component to be utilized for scaffolds and provides a microenvironment similar to that of native cartilage tissue. The DCC powder provides a platform technology upon which many cartilage, or even bone, tissue engineering scaffolds could be based.
KU researchers have invented a high-pressure reactor equipped with an internal ultrasonic mixer that is useful for preparing nanomaterials and for conducting reactions with ozone and other reactive gases. The apparatus facilitates the use of supercritical carbon dioxide (CO2) as a solvent, allowing the advantages of the solvent properties of the supercritical fluid and the agitation achievable using ultrasonic energy.
This invention provides a method for synthesizing a novel hydrogel that can switch its wettability and absorption for polar liquids and maintain its non-polar liquid repellency while requiring minimal heat input. The invention enables a separation method has the potential to reduce energy costs for some industrial processes and has been employed to separate immiscible polar-non-polar liquid mixtures (water and oil) and a completely miscible liquid mixture (ethanol and heptane) at room temperature.
This is a novel seedless floating growth technique for synthesis of a variety of hybrid nanostructures on graphene, primarily for electronic and optoelectronic applications.
Most ZnO-nanostructure devices are fabricated using time-consuming nanomanipulation or one-by-one fabrication techniques, making them unattractive for large-scale production. Despite advantages in manufacturing cost and scalability, solutions-based processing has not produced high performing ZnO thin-film devices. This novel solutions-based process produces ZnO devices with shorter response times, lower device biases, and high light sensitivity.
This novel process uses atomic layer deposition (ALD) to grow a tunnel barrier one atomic layer at a time. Placed between two electrically conducting materials, a tunnel barrier forms a tunnel junction. Electrons pass through the barrier by quantum tunneling. This process forms more uniform, thinner, and lower defect tunnel barriers. By improving the likelihood of quantum tunneling, this process creates higher performing tunnel junction devices.
The Surface Modified Ceramic Filter (SMCF) provides an inexpensive gravity filtration device for the removal of inorganic chemicals, organic chemicals, and pathogens from water. The surface modification is easily incorporated into traditional ceramic production methods, making this filter ideal for both industrial mass-production and remote operations in developing countries.
This invention uses a photoactive element between graphene electrodes to create a photovoltaic device that not only produces electricity from sunlight, but also transmits its infrared energy for use in an attached thermal energy device.
