摘要： An apparatus for fabricating a graphene membrane includes a first section having a first fluid chamber for housing a suspension of graphene platelets in a fluid. A second section is positionable adjacent the first section. The second section has a second fluid chamber and a porous support housed in the second fluid chamber for supporting a porous substrate. When the first section is positioned adjacent to the second section and the porous substrate is supported by the porous support, the first fluid chamber and the second fluid chamber are in fluid communication via the porous substrate. The apparatus further includes a pressurizer for creating a pressure differential between the first fluid chamber and the second fluid chamber and thereby forcing the fluid through the porous substrate and into the second fluid chamber and lodging the graphene platelets in the pores of the porous substrate.

摘要： Hybrid materials are disclosed including molecular/protein crystals integrated with synthetic polymers. The disclosed materials combine the structural order and periodicity of crystals, the adaptiveness and tunable mechanical properties of polymeric networks, and the chemical versatility of protein building blocks. Some of the properties of the disclosed materials include the following: 1) allows crystals-which are typically rigid and brittle—to expand and contract reversibly; 2) incorporates polymers to increase the mechanical toughness of the crystals and allow self-healing; 3) reversibly expand/contract crystal lattices and mobilize the protein components therein may provide a new means to improve X-ray diffraction quality and explore otherwise inaccessible protein structural states using 3D protein crystallography; 4) creation of chemically and mechanically differentiated domains within single crystals. Some example embodiments combine the properties of hydrogels (flexibility, adaptability, elasticity, self-healing), crystals (structural order) and proteins (chemical and genetic tailorability).

摘要： A preparation method of a high-absorptivity chitosan/bamboo activated carbon composite aerogel include: evenly mixing a chitosan suspension and bamboo activated carbon; dropwise adding glacial acetic acid and stirring to form a solution; dropwise adding a glutaraldehyde solution, and stirring until cross-linking of chitosan is completed; and freezing the obtained liquid in shape, and then performing freeze-drying by means of a vacuum freeze dryer to obtain a chitosan/bamboo activated carbon composite aerogel. The natural, environmentally friendly and degradable chitosan is used as the raw material, bamboo activated carbon is adhered to the chitosan, and the freeze-drying technique is used to prepare the aerogel, so that the bamboo activated carbon is uniformly dispersed and fixed in the three-dimensional space of the aerogel, and the prepared composite aerogel has a high specific surface area and a high porosity, and a high PM2.5 adsorption capacity.

摘要： This invention provides for removal of toxic heavy metal contamination from water using inositol hexakisphosphate. Inositol hexakisphosphate (InsP6 or IP6 aka phytic acid) is a ubiquitous polyphosphorylated carbohydrate with numerous biological and industrial functions including chelation of cations. IP6 hexa-citrate (IP6-citrate) was synthesized and characterized for use as metal chelator in the purification of water. The synthesized IP6-citrate was used to modify the surface of cellulose and the IP6-citrate-modified cellulose subsequently used to remove Pb, Cr and Cd from aqueous solutions. Atomic Absorption Spectrometry and differential pulse anodic stripping Voltammetry were used to test the levels of the heavy metals in water samples before and after the application of IP6-citrate-modified cellulose. The use of IP6-citrate modified cellulose decreased the amount of Cd, Cr and Pb in the water samples by 95-99%. IP6-citrate modified cellulose was superior to IP6-cellulose alone.
