摘要： A method of assembling a floating wind turbine platform includes forming a base assembly of the floating wind turbine platform in either a cofferdam or a graving dock built in water having a first depth. The base assembly includes a keystone and a plurality of buoyant bottom beams extending radially outward of the keystone, wherein longitudinal axes of each of the plurality of bottom beams are coplanar. The cofferdam or the graving dock is flooded and the assembled base assembly is floated to an assembly area in water having a second depth. A center column and a plurality of outer columns are assembled or formed on the base assembly, a tower is assembled or formed on the center column, and a wind turbine is assembled on the tower, thereby defining the floating wind turbine platform.

The provided methods and compositions allow for the production of composites with unexpectedly superior properties including improved impact resistance, tensile modulus of elasticity, tensile strength, and flexural modulus of elasticity as compared to previously known composites. In some embodiments, the present invention provides methods including the steps of providing cellulose nanofibrils, associating the cellulose nanofibrils with a maleic-anhydride (MA) copolymer to form a nanofibril-MA copolymer blend, preparing the nanofibril-MA copolymer blend for addition to a matrix polymer, and forming a composite by associating the nanofibril-MA copolymer blend with the matrix polymer, wherein the amount of cellulose nanofibrils in the composite is between 3% and 50% by weight of the composite.

摘要： The present invention describes tunable methods of treating cellulosic materials with a composition that provides increased hydrophobicity and/or lipophobicity to such materials without sacrificing the biodegradability thereof. The methods as disclosed provide for binding of saccharide fatty acid esters on cellulosic materials, including that the disclosure provides products made by such methods. The materials thus treated display higher hydrophobicity, lipophobicity, barrier function, and mechanical properties, and may be used in any application where such features are desired.

摘要： To improve the write performance of PCM, the disclosed technology, in certain embodiments, provides a new write scheme, referred to herein as two-stage-write, which leverages the speed and power asymmetries of writing a zero bit and a one bit. Writing a data block to PCM is divided into two separated stages, i.e., write-0 stage and write-1 stage. Without violating power constraints, during the write-0 stage, all zero bits in this data block are written to PCM at an accelerated speed; during the write-1 stage, all one bits are written to PCM, with more bits being written concurrently. In certain embodiments, the disclosed technology provides a new coding scheme to improve the speed of the write-1 stage by further increasing the number of bits that can be written to PCM in parallel.

摘要： Strong, light-weight composite laminates are made by impregnating layers of paper with a cellulose nanofiber (CNF) slurry, laying the coated papers up in a plurality of layers or stack, and subjecting the stack to pressure and heat for a period of time sufficient to cause the CNF to impregnate, reinforce, and bond the paper layers into a composite. The resulting composite has impressive mechanical strength and exhibits a substantially homogeneous composition throughout its depth. The composite should have good strength to weight properties, and be recyclable or compostable.
