Provided is a method of manufacturing a hexagonal boron nitride multilayer according to an embodiment of the inventive concept, which includes providing a catalyst substrate including iron into a tube, using a heater to raise an internal temperature of the tube to 1400? C. or higher, and providing a boron nitride precursor into the tube to form a hexagonal boron nitride multilayer on the catalyst substrate.

A continuous method for manufacturing graphene films using a metal substrate, wherein a first surface of the metal substrate is heated such that a top layer of the first surface melts to form a molten metal layer, and devices for carrying out the same.

A chemical vapor deposition method comprises flowing a carrier liquid through a reactor. A fluid comprising one or more reactants is introduced into the carrier liquid. The fluid is at a first temperature and first pressure and is sufficiently immiscible in the carrier liquid so as to form a plurality of microreactors suspended in the carrier liquid. Each of the microreactors comprise a discrete volume of the fluid and have a surface boundary defined by an interface of the fluid with the carrier liquid. The fluid is heated and optionally pressurized to a second temperature and second pressure at which a chemical vapor deposition reaction occurs within the microreactors to form a plurality of chemical vapor deposition products. The plurality of chemical vapor deposition products are separated from the carrier liquid. A system for carrying out the method of the present disclosure is also taught.

Embodiments of the present disclosure provide for substrates having an oxide shell layer (e.g., a silica shell layer), methods of making an oxide shell layer, and the like.

Inventive techniques for forming unique compositions of matter are disclosed, as well as various advantageous physical characteristics, and associated properties of the resultant materials. In particular, particles comprising polymer matrices are characterized by having carbon disposed within the polymer matrix structure thereof. The carbon is primarily, or entirely, present at interstitial sites of the polymer matrix, and may be present in amounts ranging from about 15 wt % to about 90 wt %. The carbon, moreover, forms covalent bonds with both atoms of the polymer matrix and other carbon atoms present in, but not part of, the matrix. This facilitates substantially homogeneous dispersal of the carbon throughout the resultant material, conveying unique and advantageous properties such as strength-to-weight ratio, density, mechanical toughness, sheer strength, flex strength, hardness, anti-corrosiveness, electrical and/or thermal conductivity, etc. as described herein. In some approaches, the resultant materials may be powderized or pelletized.
