Abstract: The surface hydrophobization of cellulose nanocrystals (CNCs) by carboxylic acids, biodiesel, or plant oils was conducted via there herein disclosed green process using an one-pot synthetic method. In the process, an aqueous lactic acid syrup served as a solvent to provide a stable and well-dispersed water suspension of CNCs and participated in esterification reactions to produce an intermediate product of polylactic acid (PLA) oligomer grafted CNCs (CNC-g-PLA). This solvent and intermediate product system allows for an in situ solvent exchange from water to lactic acid without prior drying of the CNCs and a subsequent efficient esterification reaction of CNCs with carboxylic acids or esters having a long hydrocarbon chain (FAs). Another advantage of the disclosed process is the ability to reuse the reagents in the subsequent reaction in order to reduce the production cost.
Abstract: Bio-derived glycerides formed from a reaction between waste glycerol and biodegradable or bio-derived fatty acid esters such as crude biodiesel or soybean oil triglycerides are useful as dust suppressants, binders, and stabilizing agents.
Abstract: An optical sensor system, comprising refractory plasmonic elements that can withstand temperatures exceeding 2500° C. in chemically aggressive and harsh environments that impose stress, strain and vibrations. A plasmonic metamaterial or metasurface, engineered to have a specific spectral and angular response, exhibits optical reflection characteristics that are altered by varying physical environmental conditions including but not limited to temperature, surface chemistry or elastic stress, strain and other types of mechanical load. The metamaterial or metasurface comprises a set of ultra-thin structured layers with a total thickness of less than tens of microns that can be deployed onto surfaces of devices operating in harsh environmental conditions. The top interface of the metamaterial or metasurface is illuminated with a light source, either through free space or via an optical fiber, and the reflected signal is detected employing remote detectors.

Abstract: The overall thermal performance of a building UATotal can be empirically estimated through a short-duration controlled test. Preferably, the controlled test is performed at night during the winter. A heating source, such as a furnace, is turned off after the indoor temperature has stabilized. After an extended period, such as 12 hours, the heating source is briefly turned back on, such as for an hour, then turned off. The indoor temperature is allowed to stabilize. The energy consumed within the building during the test period is assumed to equal internal heat gains. Overall thermal performance is estimated by balancing the heat gained with the heat lost during the test period.
Abstract: The ink of the present invention is an oil dispersion of pigment particles. The pigment particles are designed to have no or insignificant response to applied electric fields. The ink comprises a carrier liquid having a concentration of pigment particles disposed in the carrier liquid. A surfactant is included in the carrier liquid, wherein the surfactant is adsorbed on the pigment particles only when activated. The pigment particles having adsorbed the surfactant do not generate a reactive level of particle charge so that the pigment particles move with and not independently from the carrier liquid under an applied electrical field. The surfactant is activated by the application of at least one of heat and solvent to the carrier liquid so that the surfactant molecules adsorb onto the pigment particles.
Abstract: A multi-stage FWI workflow uses multiple-contaminated FWI models to predict surface-related multiples. A method embodying the present technological advancement, can include: using data with free surface multiples as input into FWI; generating a subsurface model by performing FWI with the free-surface boundary condition imposed on top of the subsurface model; using inverted model from FWI to predict multiples; removing predicted multiples from the measured data; using the multiple-free data as input into FWI with absorbing boundary conditions imposed on top of the subsurface model; and preparing a multiple free data set for use in conventional seismic data processing.

Abstract: A data storage apparatus includes a cache memory module and a NAND flash memory module including a cache memory mirror and a user data storage zone. The cache memory module is connected to the cache memory mirror via a path and electrically connected to the user data storage zone via another path. The cache memory module receives a write command that includes user data from a host, writes a copy of the user data into the user data storage zone in a write-back mode, and writes another copy of the user data cache memory mirror in a write-through mode. If some of the user data are lost from the cache memory module before they are written into the user data storage zone, the user data written in the cache memory mirror are copied and written into the cache memory module when the data storage apparatus is initiated again.

Abstract: The vertical vibration isolation system of the present invention includes a bearing base, a guide rail assembly and a plurality of buckling elements. The bearing base has an upper platform that can move along a vertical direction. The guide rail assembly surrounds the bearing base and has a plurality of arc-shaped sliding channels. The top portion of each buckling element can move with the upper platform, while the bottom portion of each buckling element is slidably connected to the corresponding arc-shaped sliding channel. The vertical displacement of the upper platform would cause different degrees of buckling of the buckling elements and also induces sliding motion of the bottom portion of the buckling elements along the arc-shaped sliding channels. Accordingly, the vertical vibration isolation system can provide nonlinear restoring force by buckling and sliding mechanisms so as to exhibit vertical vibration isolation effect.
