摘要： Formulations and methods for papermaking are disclosed herein using one or more volatile debonders, where the volatile debonder forms a solution or an emulsion with water in a paper precursor, and where the volatile debonder is evaporable from the paper precursor before the paper precursor is completely dried to form a paper sheet during papermaking. Two volatile debonders having different boiling points can be used, where they are miscible in water and in each other, and where one volatile debonder has a higher molecular weight and the other volatile debonder has a lower boiling point.

摘要： A method of making a measurement of binding affinity of a sample comprises the steps of: introducing the sample into a well having a bottom formed as a photonic crystal biosensor, wherein a portion of the sample becomes bound to the biosensor; making a measurement of the change in the shift in peak wavelength value as a function of time (kon) from the well as the sample is introduced into the well; simultaneously dispensing the sample to the well and aspirating the sample from the well and measuring the change in the shift in peak wavelength value as a function of time (koff) during the simultaneous dispensing and aspirating, and calculating an equilibrium association constant or an equilibrium dissociation constant for the sample from the values of kon and koff.

摘要： Disclosed herein are systems and methods for attaching particulate additives to a population of cellulose fibers dispersed in an aqueous solution. The cellulose fibers are treated with an activator that forms complexes with them. The particulate additive is attached to a tether that is capable of interacting with the activator, thereby forming a tether-bearing particulate additive. The tether-bearing particulate additive can be added to the activated suspension of cellulose fibers. The resulting interaction between the tether and the activator forms durable complexes that attach the particulate additive to the cellulose fibers. Using these systems and methods, useful additives like starches can be attached to cellulose fibers, imparting advantageous properties such as increased strength to paper products formed thereby. These systems and methods are particularly useful for papermaking involving virgin pulp fibers, recycled fibers, or any combination thereof.

摘要： A grating-based sensor is disclosed that has a grating structure constructed and designed for both evanescent resonance (ER) fluorescence detection and label-free detection applications. Some embodiments are disclosed which are optimized for ER detection in an air mode, in which the sample is dry. Other embodiments are optimized for ER detection in liquid mode, in which the sample is suspended in liquid medium such as water. One and two-dimensional gratings are also disclosed, including gratings characterized by unit cells with central posts, central holes, and two-level, two-dimensional gratings. A readout system for such sensors is also disclosed. One embodiment includes a first light source optimized for collecting label-free detection data, a second light source optimized for collecting ER fluorescence amplification data, and at least one detector. In one embodiment, the detector is an imaging system and includes a CCD camera for collecting both ER and label-free data. In other embodiments, the at least one detector takes the form of a spectrometer for collection of label-free data and a photomultiplier for collecting ER data. In other embodiments, a single light source such as a tunable laser or broad band light source is used.

摘要： Compositions and methods of producing an optically-enhanced paper-based material are disclosed. The composition can include an optical brightening agent and an additive having an aromatic portion, where the aromatic portion is associated with an optical brightening agent. The paper-based material can exhibit a higher capacity for the optical brightening agent relative to a paper-based material that lacks the additive. Techniques for increasing optical brightening agent retention in a paper-based material are also disclosed. The techniques include using an additive having an aromatic portion, where the aromatic portion associates with an optical brightening agent so that the retention of the optical brightening agent is improved.
