摘要： This disclosure concerns a method of forming a porous material, comprising impregnating a porous polymer with a pore-forming agent in order to form an impregnated polymer, and at least partially carbonising the impregnated polymer at a temperature of about 150° C. to about 500° C. in order to form the porous material. The porous material is characterised by a crystallinity of about 10% to about 70% relative to the porous polymer. This disclosure also concerns the porous material thereof.

摘要： A method for producing a carbon nanomaterial (CNM) product includes: heating an electrolyte media to obtain a molten electrolyte media; positioning the molten electrolyte media between a high-nickel content anode and a cathode of an electrolytic cell; introducing a source of carbon into the electrolytic cell; applying an electric current to the cathode and the anode in the electrolytic cell; and collecting the CNM product from the cathode, in which the CNM product comprises a minimal relative-amount of at least 70 wt %, as compared to a total weight of the CNM product, of hollow nano-onion product, in which the high-nickel content anode is made of pure nickel or an alloy that comprises greater than 50 wt % nickel.

摘要： A biofabrication method for producing cellulose-based materials. The method includes providing active cellulose-producing bacteria such as Gluconacetobacter and culturing media in a container; combining organic additives or inorganic additives with the active cellulose-producing bacteria in the container to produce a cellulose hydrogel matrix composed of entangled bacteria-produced cellulose nanofibers; controlling a concentration of the additives in the cellulose hydrogel matrix; and exposing the cellulose hydrogel matrix in selected thermal environment to create a biofabricated functional material.
