Publication number: 20150340091Abstract: 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.Type: ApplicationFiled: December 20, 2013Publication date: November 26, 2015Applicant: UNIVERSITY OF MAINE SYSTEM BOARD OF TRUSTEESInventors: Yifeng ZHU, Jianhui YUE

Patent number: 9068291Abstract: A system and method for hardwood pulp liquid hydrolysate conditioning includes a first evaporator receives a hardwood mix extract and outputting a quantity of vapor and extract. A hydrolysis unit receives the extract, hydrolyzes and outputs to a lignin separation device, which separates and recovers a quantity of lignin. A neutralization device receives extract from the lignin separation device and a neutralizing agent, producing a mixture of solid precipitate and a fifth extract. The solid precipitate is removed from the fifth extract. A second evaporator removes a quantity of acid from the fifth extract in a vapor form. This vapor may be recycled to improve total acid recovery or discarded. A desalination device receives the diluted extract, separates out some of the acid and salt and outputs a desalinated solution.Type: GrantFiled: November 13, 2013Date of Patent: June 30, 2015Assignees: Red Shield Acquisition, LLC, University of Maine System Board of TrusteesInventors: Darrell Waite, Richard Arnold, James St. Pierre, Hemant P.

Publication number: 20150167243Abstract: A scalable, energy efficient process for preparing cellulose nanofibers is disclosed. The process employs a depolymerizing treatment with one or both of: (a) a relatively high charge of ozone under conditions that promote the formation of free radicals to chemically depolymerize the cellulose fiber cell wall and interfiber bonds; or (b) a cellulase enzyme. Depolymerization may be estimated by pulp viscosity changes. The depolymerizing treatment is followed by or concurrent with mechanical comminution of the treated fibers, the comminution being done in any of several mechanical comminuting devices, the amount of energy savings varying depending on the type of comminuting system and the treatment conditions. Comminution may be carried out to any of several endpoint measures such as fiber length, % fines or slurry viscosity.Type: ApplicationFiled: June 13, 2013Publication date: June 18, 2015Applicant: University of Maine System Board of TrusteesInventors: Michael A.

Publication number: 20150033983Abstract: Building materials are generated by the simple mixing of cellulose nanofiber (CNF) slurry with typical wood-derived material such as wood meal, optionally with mineral particulate materials, and dried. Particle boards are made with wood meal particulates; wallboards are made with wood particulates and mineral particulates; paints are made with pigment particulates; and cement is made with aggregate particulates. The particle board samples were tested for fracture toughness. The fracture toughness was found to be from 20% higher up to ten times higher than the typical value for similar board, depending on the formulation. For cases of 20% by weight cellulose nanofibers and 80% wood, the fracture toughness was more than double that of typical particle board. The process sequesters carbon and oxygen into the building product for its lifespan—typically decades—and avoid releasing CO2 into the atmosphere.Type: ApplicationFiled: July 30, 2014Publication date: February 5, 2015Applicant: University of Maine System Board of TrusteesInventors: Michael A.
