  • Patent number: 9815910
    Abstract: Hydrophobic CNCs were successfully prepared by grafting amine- and thiol terminated hydrocarbons to CNCs that have been previously coated with plant polyphenols. Hydrocarbons of various chain lengths can be used to tune the hydrophobicity of the modified CNCs. After the surface modification process, CNCs can be easily redispersed in nonpolar solvents highlighting the potential of the hydrophobic CNCs in, for example, CNC reinforced nanocomposites and non-aqueous formulations.

  • Patent number: 9574987
    Abstract: A sample of porous material is placed in a calorimeter cell and a pressure in the cell is increased starting from a pressure value of a first step by filling the cell with a wetting fluid. Measurements are taken of a heat flow to the cell and a fluid volume at each step. Then, the pressure in the cell is decreased to the pressure value of a first step with continued measurements of the heat flow to the cell. Increase and following decrease of the fluid pressure in the cell are repeated at least once. Then a temperature in the cell is decreased below a wetting fluid crystallization point. Once the fluid has been fully crystallized in sample pores, the temperature in the cell is increased above a wetting fluid melting point. Wetting limiting angle of the pores filled with fluid, and pore sizes are determined based on the results of heat flow measurements with due consideration of heat effect of fluid compression.

  • Patent number: 9394176
    Abstract: A method for forming a carbon nanotube film is disclosed. More than one carbon nanotube array is transferred onto a surface of more than one substitute substrate. The substitute substrates are arranged side by side to contact and combined side surfaces of the plurality of carbon nanotube arrays with each other by van der Waals attractive force to form an assembling array. The assembling array is larger than the carbon nanotube array. Carbon nanotube segments are drawn from the assembling array.

  • Patent number: 9345119
    Abstract: In particular embodiments, the present disclosure provides targets including a metal layer and defining a hollow inner surface. The hollow inner surface has an internal apex. The distance between at least two opposing points of the internal apex is less than about 15 ?m. In particular examples, the distance is less than about 1 ?m. Particular implementations of the targets are free standing. The targets have a number of disclosed shaped, including cones, pyramids, hemispheres, and capped structures. The present disclosure also provides arrays of such targets. Also provided are methods of forming targets, such as the disclosed targets, using lithographic techniques, such as photolithographic techniques. In particular examples, a target mold is formed from a silicon wafer and then one or more sides of the mold are coated with a target material, such as one or more metals.

  • Patent number: 9309122
    Abstract: The preparation of graphene, mono-, bi- and multi-layers from graphite-based precursor materials, for example, pencil lead or graphite, by a method of mechanical thinning on the surface of a planar substrate with controlled roughness, followed by sonication in order to collect the graphene deposited on the substrate in a liquid medium. The bearing force during thinning by mechanical friction enables the number of graphene sheets deposited on the surface of the substrate to be controlled.
