摘要： Dried nanocrystalline cellulose (NCC), in particular films of NCC, of controlled water dispersibility and a method to control the dispersibility of dried NCC by controlling electrolyte solution ionic strength and ion valency is described. Neutral M-NCC suspensions containing monovalent counterions (e.g., M=Na+, K+, NH4+, Et4N+) produced by neutralization of acid-form NCC (H-NCC) with the appropriate hydroxide, are readily dispersible in water when fully dried; this is in contrast to H-NCC. The dispersion of dried M-NCC in aqueous media is effectively prevented by a combination of (1) increased electrolyte concentration and ionic strength, and (2) higher valency of the cation component of the dissolved salt. Additionally, pre-treatment of dried M-NCC films with an electrolyte solution having a polyvalent cation, for example a divalent or trivalent cation is sufficient to prevent the subsequent dispersion of the M-NCC film in pure water.
摘要翻译：描述了干燥的纳米晶纤维素（NCC），特别是NCC的膜的受控水分散性，以及通过控制电解质溶液的离子强度和离子价态来控制干燥的NCC的分散性的方法。通过用合适的氢氧化物中和酸形式NCC（H-NCC）产生的含有一价抗衡离子（例如M = Na +，K +，NH 4 +，Et 4 N +）的中性M-NCC悬浮液在完全干燥时容易分散在水中; 这与H-NCC相反。干燥的M-NCC在水性介质中的分散体通过（1）增加的电解质浓度和离子强度的组合和（2）溶解盐的阳离子组分的更高的价态被有效地预防。另外，用具有多价阳离子（例如二价或三价阳离子）的电解质溶液预处理干燥的M-NCC膜足以防止M-NCC膜随后在纯水中分散。

摘要： Dried forms of nanocrystalline cellulose (NCC) with controllable redispersibility in water are provided; lightweight and easily transportable dried acid-form nanocrystalline cellulose which can be resuspended for use in a desired application can be produced by maintaining the humidity content of the NCC within a specific, low, range; evaporated acid-form NCC suspensions with moisture contents below this range are non-dispersible and therefore can be subsequently fixed in permanently dried form; the second form is produced by exchanging the proton of the acid-form NCC for neutral monovalent counterions and freeze-drying the NCC to give a solid product which rapidly disperses when placed in water; properties similar to those of the original suspension are also obtained with a brief sonication treatment.

摘要： A new method to control the iridescence color of solid nanocrystalline cellulose (NCC) films by ultrasound and high-shear (mechanical) energy input to the NCC suspension prior to film formation is provided. As the energy input to the NCC suspension increases, the resulting film color shifts from the ultraviolet region towards the infrared region of the electromagnetic spectrum; this wavelength shift lies in the opposite direction to that caused by the addition of electrolytes to NCC suspensions prior to film formation. No additives are required to achieve the changes in color; color changes can also be effected by mixing two suspensions exposed to different levels of sonication.
摘要翻译：提供了一种通过在成膜之前通过超声和高剪切（机械）能量输入到NCC悬浮液来控制固体纳米晶体纤维素（NCC）膜的彩虹色的新方法。随着对NCC悬浮液的能量输入的增加，所得到的膜颜色从紫外线区域向电磁光谱的红外区域移动; 这种波长偏移与在成膜之前向NCC悬浮液中加入电解质所引起的方向相反。不需要添加剂来实现颜色的变化; 也可以通过混合暴露于不同程度的超声处理的两种悬浮液来实现颜色变化。

摘要： A new method to produce solid nanocrystalline cellulose (NCC) films containing patterns by differential heating of aqueous suspensions of NCC has been discovered. When acid-form NCC suspensions are dried by heating to temperatures above 50° C., darkening of the NCC can occur, while neutral forms of NCC can produce iridescent chiral nematic films by heating to temperatures up to 105° C. Placing materials of different thermal conductivity beneath the container containing an evaporating NCC suspension results in watermark-like patterns of different iridescent colour imprinted within the film structure. Other colloidal rod-like particles can be employed in place of nanocrystalline cellulose (NCC), for example chitin or chitosan.

摘要： A new method to control the dispersibility of dried nanocrystalline cellulose (NCC) by controlling solution pH and ionic strength is provided; when stable, non-reswellable acid-form NCC (H-NCC) films are placed in concentrated sodium hydroxide solutions, they swell but do not disperse; while sodium-form NCC (Na-NCC) or other NCC films having neutral monovalent counterions readily disperse in pure water, Na-NCC films placed in hydrochloric acid and sodium chloride as well as sodium hydroxide solutions of sufficient ionic strength swell, but do not disperse; similar properties are observed for freeze-dried NCC products. The dispersibility of these NCC films is a function of the ionic strength and the identity of the electrolyte solutions to which they are exposed. NCC films are envisaged that have barrier properties in an electrolyte solution but that disintegrate or disperse when rinsed with pure water at the end of their useful lifespan.

摘要： There is provided a method for processing data sets in a processor. The processor has a pipelined data path including an input, an output, and at least one discrete stage. The pipeline is configured to enable one or more data sets, each comprising one or more data items, to enter the pipeline from the input, propagate through the pipeline, and exit the pipeline through the output. Each discrete stage represents an operation to be performed on the data item occupying the discrete stage. The method comprises defining one or more non-overlapping sections of the pipeline corresponding to portions of the pipeline occupied by the data items of at least one data set. In addition, the method comprises providing one or more logic units, each dedicated to control the progress of the data items of the at least one data set through the pipeline as the section advances through the pipeline.
