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.
